Abstract:
Loading into containers must consider the level of efficient use of container space. The use of empty space and the arrangement of goods in containers that have not been optimal are problems in the process of loading goods. In this regard, the plan for the preparation of goods to be made by researchers is assisted with a software that will facilitate the optimal arrangement of goods arranged in containers. The parameters are reviewed from the aspect of purpose, weight, volume, and type of goods to see whether the optimal use of goods. Cube IQ became the software chosen to help implement the system in this study by determining the coordinates and 3D visualization of the arrangement of goods in containers. Goods data and container data become the data used in the simulation process. Dimensions (length, width, height) define the required item data. While dimensions (maximum weight and volume of containers) defines the required container data. After simulating the Cube IQ software there was an increase in the use of container capacity by 88.35% while manually only 87.91%. The implication is a decrease in distribution costs per unit, which is 0.5%. The optimization results obtained are expected to be able to provide input in making decisions determining the optimal arrangement of goods and fleet numbers.AbstrakPemuatan ke dalam kontainer harus mempertimbangkan tingkat efisiensi penggunaan ruang kontainer.

Abstract:
This study aims to analyze the impact of agglomeration in the form of localization economies and urbanization economies on the productivity of manufacturing industrial companies in Indonesia. Unlike previous studies, this study will look at the effect of technology level on the relationship between productivity and agglomeration by classifying research samples into low-tech and high-tech industries. In addition, this study also improves the estimation technique by addressing the endogeneity problem that has the potential to arise in estimating the relationship between productivity and agglomeration to be overcome by using instrument variable (IV). The study was conducted in two stages of estimation using company-level panel data from 2010 to 2014. First, productivity was measured at the company level using Total Factor Productivity (TFP). Then, the company productivity is estimated together with the company and industry characteristic variables, including the agglomeration measurement variable which represents localization economies and urbanization economies. The regression results show a positive impact from localization economies and a negative impact from urbanization economies.AbstrakPenelitian ini bertujuan menganalisis dampak aglomerasi berupa localization economies dan urbanization economies terhadap produktivitas perusahaan industri manufaktur di Indonesia.

Abstract:
Global energy consumption increases every year. BP Statistics Review of World Energy 2019 shows that Indonesia's energy consumption increases by 4.9% in 2018, reaching 185.5 million tons of oil equivalent (TOE). Therefore, oil and gas companies must increase production to fulfill those needs. PT Pertamina EP is a subsidiary of PT Pertamina (Persero) which focuses on the upstream oil and gas sector. One of the activities carried out in the upstream business is drilling. Drilling materials are necessary to support the dynamic of drilling process. The mechanism used when there is a shortage of stock is to send the required material from another field that has the required material, or is called Inter Unit Assistance (BAU). In 2018 the costs incurred for transportation of BAU OCTG (Oil Country Tubular Goods) material amounted to Rp 45,733,340,000. Distribution center is an alternative for cutting distribution chains. We proposed allocation of facility such distribution center location decision using p-median optimization model to reduce the BAU transportation cost. This approach is implemented using math programming using AMPL and Gurobi. Distribution center functions as a material distribution center to meet the needs of the surrounding fields. By applying the scenario of building a distribution center, transportation costs can be reduced by 13% or Rp 6,167,325,000. AbstrakKonsumsi energi global cenderung meningkat setiap tahunnya. Data BP Statistical Review of World Energy 2019 menunjukkan konsumsi energi Indonesia meningkat sebesar 4,9% pada tahun 2018 dengan nilai mencapai 185,5 juta tonnes oil equivalent (TOE). Oleh karena itu perusahaan minyak dan gas bumi (migas) harus meningkatkan produksi untuk memenuhi kebutuhan tersebut. PT Pertamina EP adalah perusahaan yang fokus pada sektor hulu migas. Salah satu kegiatan yang dilakukan pada bisnis hulu adalah pemboran. Untuk Rencana pengeboran yang dinamis dibutuhkan ketersediaan material. Mekanisme yang dilakukan saat terjadi kekurangan stock adalah mengirim material yang dibutuhkan dari field lain yang memiliki ketersediaan material yang dibutuhkan, atau disebut Bantuan Antar Unit (BAU). Biaya yang dikeluarkan pada tahun 2018 untuk transportasi BAU material OCTG (Oil Country Tubular Goods) sebesar Rp 45.733.340.000. Biaya tersebut dibutuhkan untuk mendistribusikan material pada lokasi field yang tersebar di berbagai lokasi di pulau Jawa, Sumatera, dan Kalimantan. Dalam penelitian ini diusulkan untuk memanfaatkan penggunaan distribution center (DC) sebagai upaya untuk menghemat biaya transportasi BAU. DC berfungsi sebagai pusat distribusi material untuk memenuhi kebutuhan field di sekitarnya. Model optimasi p-median digunakan memilih lokasi fasilitas DC yang memiliki biaya transportasi paling minimal dengan mempertimbangkan jarak, biaya, dan permintaan material. Diasumsikan satu DC akan ditempatkan di setiap wilayah / pulau. Solusi optimal dari model p-median dihasilkan menggunakan software pemrograman matematis AMPL dengan menggunakan solver GUROBI. Hasil eksperimen didapatkan bahwa dengan penerapan skenario adanya DC, biaya transportasi dapat dipangkas sebesar 13% atau sebesar Rp 6.167.325.000.

Abstract:
Two-echelon location routing problem (2E-LRP) is a problem that considers distribution problem in a two-level / echelon transport system. The first echelon considers trips from a main depot to a set of selected satellite. The second echelon considers routes to serve customers from the selected satellite. This study proposes two metaheuristics algorithms to solve 2E-LRP: Simulated Annealing (SA) and Large Neighborhood Search (LNS) heuristics. The neighborhood / operator moves of both algorithms are modified specifically to solve 2E-LRP. The proposed SA uses swap, insert, and reverse operators. Meanwhile the proposed LNS uses four destructive operator (random route removal, worst removal, route removal, related node removal, not related node removal) and two constructive operator (greedy insertion and modived greedy insertion). Previously known dataset is used to test the performance of the both algorithms. Numerical experiment results show that SA performs better than LNS. The objective function value for SA and LNS are 176.125 and 181.478, respectively. Besides, the average computational time of SA and LNS are 119.02s and 352.17s, respectively.AbstrakPermasalahan penentuan lokasi fasilitas sekaligus rute kendaraan dengan mempertimbangkan sistem transportasi dua eselon juga dikenal dengan two-echelon location routing problem (2E-LRP) atau masalah lokasi dan rute kendaraan dua eselon (MLRKDE). Pada eselon pertama keputusan yang perlu diambil adalah penentuan lokasi fasilitas (diistilahkan satelit) dan rute kendaraan dari depo ke lokasi satelit terpilih. Pada eselon kedua dilakukan penentuan rute kendaraan dari satelit ke masing-masing pelanggan mempertimbangan jumlah permintaan dan kapasitas kendaraan. Dalam penelitian ini dikembangkan dua algoritma metaheuristik yaitu Simulated Annealing (SA) dan Large Neighborhood Search (LNS). Operator yang digunakan kedua algoritma tersebut didesain khusus untuk permasalahan MLRKDE. Algoritma SA menggunakan operator swap, insert, dan reverse. Algoritma LNS menggunakan operator perusakan (random route removal, worst removal, route removal, related node removal, dan not related node removal) dan perbaikan (greedy insertion dan modified greedy insertion). Benchmark data dari penelitian sebelumnya digunakan untuk menguji performa kedua algoritma tersebut. Hasil eksperimen menunjukkan bahwa performa algoritma SA lebih baik daripada LNS. Rata-rata nilai fungsi objektif dari SA dan LNS adalah 176.125 dan 181.478. Waktu rata-rata komputasi algoritma SA and LNS pada permasalahan ini adalah 119.02 dan 352.17 detik.

Abstract:
The performance of suppliers both directly and indirectly determines several critical points for the company such as: product prices, product availability in the market, and product quality. It is very important for companies to monitor and improve the quality of raw materials obtained from suppliers, because this will determine the performance of the company, especially on the quality of products produced. The quality monitoring system implemented in the company must be responsive and consider every critical aspect of the non-conformity that occurs, not only using the Supplier Correction Action Request (SCAR) form or the Vendor Corrective Action Request (VCAR) form or the Supplier Corrective and Preventive Action Request (SCPAR) form for all types of non-conformity found. In this study, samples were taken at 3 different companies in order to obtain valid data to analyze and evaluate the existing quality monitoring system to get a new quality monitoring system that more responsive to avoid repeated findings occur. The research method was conducted by classifying non conformity types based on the level of criticism using the Total Quality Management (TQM) approach, fishbone diagrams, Failure Mode and Effect Analysis (FMEA), and Quality Function Deployment (QFD) so that the quality monitoring system produced is more accurate, effective and efficient in handling raw material non-conformities that occur. AbstrakKinerja pemasok baik secara langsung maupun tidak langsung ikut menentukan beberapa point kritikal bagi perusahaan seperti: harga produk, ketersediaan produk di pasar, dan kualitas produk. Sangat penting bagi perusahaan untuk memonitor dan meningkatkan kualitas bahan baku yang diperoleh dari pemasok, karena hal ini akan menentukan performa bagi perusahaan terutama terhadap kualitas produk yang dihasilkan. Sistem monitoring kualitas yang diterapkan di perusahaan harus responsif dan mempertimbangkan setiap aspek kritikal ketidaksesuaian yang terjadi, tidak bisa hanya menggunakan Supplier Correction Action Request (SCAR) form atau Vendor Corrective Action Request (VCAR) form atau Supplier Corrective and Preventive Action Request (SCPAR) form untuk semua tipe non conformity atau ketidaksesuaian yang ditemukan. Dalam penelitian ini, dilakukan pengambilan sampel di 3 perusahaan yang berbeda dengan tujuan agar didapatkan data valid guna menganalisis mengenai sistem monitoring kualitas yang telah ada saat ini dan mengevaluasi untuk mendapatkan sistem monitoring kualitas baru yang lebih responsif sehingga tidak terjadi lagi temuan berulang. Metode penelitian dilakukan dengan mengklasifikasikan tipe non conformity berdasarkan tingkat kritikalnya menggunakan pendekatan Total Quality Management (TQM), penggunaan fishbone diagram, Failure Mode and Effect Analysis (FMEA), dan Quality Function Deployment (QFD) sehingga sistem monitoring kualitas yang dihasilkan lebih akurat, efektif dan efisien dalam penanganan ketidaksesuaian bahan baku yang terjadi.

Abstract:
The effect of import liberalization on industrial productivity can occur through increased access to inputs and technology transfer to imported products. Another factor that can affect productivity is product complexity. The calculation results of the 2010-2014 Product Complexity Index (PCI) based on the concept of diversity and ubiquity, showed the average 3-digit PCI ISIC was 0.0946 with a minimum value of -2.1324 and a maximum of 2.2157. This study aims to look at the effect of imported raw materials on the productivity of companies that produce more complex products. By using the 2010-2014 Large and Medium Industry Survey data and involving the firm's fixed effects and time, empirical results show that imports of raw materials significantly affect the productivity of companies that produce complex products by -0.0405. In addition, it is known that the manufacturing industry takes approximately one year to absorb technology in complex products so as to increase firm productivity. Firm-level productivity is calculated based on the Levinshon-Petrin (2003) estimated productivity to control selection and simultaneity bias.ABSTRAK Efek liberalisasi impor terhadap produktivitas industri dapat terjadi melalui peningkatan akses input serta transfer teknologi pada produk impor. Faktor lainnya yang dapat mempengaruhi produktivitas adalah kompleksitas produk. Hasil perhitungan Product Complexity Index (PCI) 2010-2014 berdasarkan konsep keragaman dan ubiquity, menunjukkan rata-rata PCI ISIC 3 digit adalah 0.0946 dengan nilai minimum -2.1324 dan maksimum 2.2157. Penelitian ini bertujuan untuk melihat pengaruh impor bahan baku terhadap produktivitas perusahaan yang lebih banyak menghasilkan produk kompleks. Dengan menggunakan data Survei Industri Besar dan Sedang tahun 2010-2014 serta melibatkan efek tetap perusahaan dan waktu, hasil empiris menunjukkan impor bahan baku mempengaruhi produktivitas perusahaan yang menghasilkan produk kompleks secara signifikan sebesar -0.0405. Selain itu, diketahui bahwa industri manufaktur memerlukan waktu kira-kira satu tahun untuk menyerap teknologi pada produk kompleks sehingga dapat meningkatkan produktivitas perusahaan. Produktivitas level perusahaan dihitung berdasarkan estimasi produktivitas Levinshon-Petrin untuk mengendalikan bias seleksi dan simultanitas.

Abstract:
In strategy competition, innovation must be clear and precise in accordance with consumer demand and expectations. Limited organizational resources require organizations to manage innovation clearly. The company's efforts to change or increase product output, both from its processes and services, are interpreted as innovation. This study aims to examine the effect of total quality management on company performance with two approaches, additional innovation and radical innovation. The hypothesis was tested from data collected from 108 food and beverage SMEs registered at the Indonesian Food and Beverage Entrepreneurs Association - GAPMMI using convenience sampling data processed with AMOS. The results of the study show that additional innovation as a TQM mediator has an influence on company performance. In addition, testing shows that radical innovation has no effect on company performance. Therefore, additional innovation is the best way that SMEs can choose as a TQM approach to influence company performance. This research can contribute to small and medium enterprises in the selection of innovations in the practice of TQM. This will help entrepreneurs get better company performance Key words: total quality management; incremental innovation; radical innovation; firm performance; SMEs AbstrakDalam kompetisi strategi, inovasi harus jelas dan tepat sesuai dengan permintaan dan harapan konsumen. Terbatasnya sumber daya organisasi menuntut organisasi mengelola inovasi dengan jelas. Upaya perusahaan untuk mengubah atau meningkatkan output produk, baik dari proses dan layanannya, ditafsirkan sebagai inovasi. Penelitian ini bertujuan untuk meneliti pengaruh manajemen kualitas total terhadap kinerja perusahaan dengan dua pendekatan, inovasi tambahan dan inovasi radikal. Hipotesis diuji dari data yang dikumpulkan dari 108 UKM makanan dan minuman yang terdaftar di Gabungan Pengusaha Makanan dan Minuman Indonesia – GAPMMI dengan menggunakan convenience sampling data diolah dengan AMOS. Hasil penelitian menunjukkan bahwa inovasi tambahan sebagai mediator TQM, memiliki pengaruh terhadap kinerja perusahaan. Selain itu, pengujian menunjukkan bahwa inovasi radikal tidak berpengaruh pada kinerja perusahaan. Oleh karena itu, inovasi tambahan adalah cara terbaik yang dapat dipilih oleh UKM sebagai pendekatan TQM untuk mempengaruhi kinerja perusahaan. Penelitian ini dapat berkontribusi untuk usaha kecil dan menengah dalam pemilihan inovasi dalam praktik TQM.

Abstract:
By following WHO guidelines, the minimum blood availability is 2% of the population. The total population of Indonesia in 2016 is 261.115.456, so ideally it takes 5.222.309 blood bags. In 2013-2015 for 36 months, there were 26 overstock events and 10 stockout events. The data shows that the frequency of over-supply is more frequent than over-demand. The high overstock has an impact on the high costs incurred by the City of Bandung PMI, if there is overstock there are two costs to be incurred, namely the cost of storing if the blood is still in good use and the cost of overstock if the blood is more than the expiration date. The purpose of this study was to determine the optimal value of inventory levels to reduce wastage of blood culling due to overstock occurring at PMI Bandung. The research method uses a quantitative approach to the optimization model of inventory policy, namely Uncertainty EOQ. The optimal amount of supplies that must be provided is at intervals of 8,705 - 9,375 blood bags with a large safety stock 403 blood bags and the ordering point is at the level of supplies of 5.706 blood bags. This proposal can provide a total inventory cost savings of Rp6.622.659.034/year. Keywords: Blood, Overstock, EOQ, Uncertainty Abstrak Sesuai dengan panduan WHO, ketersediaan darah minimal adalah 2% dari jumlah penduduk. Jumlah penduduk Indonesia tahun 2016 adalah 261.115.456 jiwa, maka idealnya dibutuhkan 5.222.309 kantong darah. Tahun 2013-2015 selama 36 bulan, terdapat 26 kejadian overstock dan 10 kejadian stoc-kout. Data tersebut menunjukan bahwa frekuensi over-supply lebih sering dibandingkan over-demand.

Abstract:
Perusahaan yang memiliki keinginan untuk memenangkan persaingan yang terus meningkat di era globalisasi, perlu terus menerus melakukan perbaikan metode pengendalian persediaan suku cadangnya. Metode existing di perusahaan memiliki beberapa kekurangan seperti belum mempertimbangkan standar deviasi demand dan service level yang dikehendaki oleh perusahaan. Tujuan kajian ini adalah melakukan perbaikan pengelolaan persediaan suku cadang dengan menerapkan model yang memiliki karakteristik pengadaan yang sesuai dengan perusahaan. Model Fixed Time Period (FTP) adalah model yang sesuai karena telah memenuhi karakteristik pengelolaan persediaan di perusahaan seperti pemesanan barang dengan interval waktu yang konstan dan demand yang berfluktuatif. Hasil menunjukkan bahwa jumlah pemesanan pada suku cadang bandsaw dengan menggunakan metode existing perusahaan di tahun 2018 selalu lebih tinggi quantity ordernya dibandingkan dengan menggunakan metode FTP. Berbeda dengan suku cadang bandsaw, suku cadang thermoc, jumlah order dengan metode FTP tidak selalu lebih rendah; bahkan metode FTP seringkali lebih tinggi atau pun sama quantity ordernya pada tahun 2018. Kata Kunci: Analisis ABC, Metode Fixed Time Period, Manajemen Inventori The company that has the desire to winning the increasing competition in the era of globalization need to improve the method of spare parts inventory control continually. Existing approaches in companies have several disadvantages such as not considering the standard deviation of demand and service level desired by the company. The purpose of this study is to improve the management of spare parts inventories by implementing a model that have right characteristics that are in line with the company. The Fixed Time Period (FTP) model is an appropriate model because it has fulfilled the characteristic of inventory management in companies such as ordering goods with constant time intervals and fluctuating demand. The results show that the number of orders on bandsaw parts using the existing company method in 2018 always has a higher order quantity than using the FTP method. Unlike bandsaw parts, thermoc parts, the number is not still lower; even the FTP method was often higher or equal to the order quantity in 2018.

Abstract:
: Regardless the benefits of imported inputs, uncertainties in foreign markets and highly sunk inisial costs (e.g. cost of searching foreign suppliers), become a barrier to entry for most of firm and causing persistent to use the imported input. However, the sunk cost entry give the information insentives about import activities for the importer. So, when importers are neighboring in a location, they pottentially induce knowledge spillovers to the other firms. The more importers at that location, the more knowledge is spread, so that it can potentially reduce initial import costs and increase the prospensity to import for other neighbors. This study uses dynamic panel data of Indonesian manufacturing firms from 2007 until 2015, to examine the determinant of decision to import, especially sunk cost and spillovers. The results of the GMM difference estimation indicate that firm who imported last year and two years earlier more likely to import input this year, both for domestic and foreign firms. This study also found a positive correlation between probability of importing input and the number of importer in the same region regardless of their industrial affiliation. However, this finding is limited only to indegenous firm which generated by agglomeration of indegenous importers.Keywords: decision to import, sunk cost of import entry, spillover, dynamic panel dataAbstrak : Terlepas dari manfaat imported input, ketidakpastian di pasar luar negeri dan biaya inisial yang tinggi dan sunk mencegah sebagian besar perusahaan untuk mengimpor dan menyebabkan perusahaan persisten mengimpor bahan baku. Namun, sunk cost entry tersebut sarat akan informasi terkait aktivitas impor, sehingga berpotensi menimbulkan knowledge spillover ketika importir berdekatan di satu lokasi tertentu. Semakin banyak importir di lokasi tersebut, semakin banyak informasi yang tersebar, sehingga dapat mengurangi biaya inisial impor dan meningkatkan kecenderungan untuk mengimpor bagi perusahaan lain. Penelitian ini mengunakan data panel dinamis perusahaan manufaktur di Indonesia (2007 - 2015) untuk mempelajari determinan keputusan impor bahan baku, terutama sunk cost entry dan import spillover. Hasil estimasi GMM difference menunjukkan perusahaan yang mengimpor satu dan dua tahun sebelumnya cenderung akan mengimpor bahan baku tahun ini, baik bagi perusahaan domestik maupun asing. Penelitian ini juga menemukan adanya hubungan positif antara keputusan impor dengan jumlah importir yang berada di satu kabupaten baik di industri yang sama maupun berbeda. Namun, temuan tersebut terbatas hanya terjadi bagi perusahaan domestik yang berasal dari aglomerasi importir domestik.Kata kunci: keputusan untuk impor, sunk cost import entry, spillover, data panel dinamis

Abstract:
: The research objectives is to analyze agglomeration over the company’s productivity of 2 important factors of agglomeration: interindustry (localization) and cross industry spillover (urbanization) and review its effect if those agglomeration derives from upstream or downstream industry. In addition to it, this research is determining on how geographic distance and economic distance against spillover strength. By means of the company‘s level panel data of heavy and medium industrial survey result by the National Statistical Bureau in local regency/municipality level ranging from 2008 to 2015 and 2010 output input table to see the vertical industry relation, the outcomes may show that both company accepting positive and significant impact on productivity spillover of the same industrial sector, and other industrial sector in the same region. Nevertheless, the more far the area geographically, the less its impact. Productivity spillover is also determined from upstream dan downstream industries concentrating in the same region. However, the economic distance effect is not identified on the upstream level. Hence, the policy implication of the research result is to encourage and shaping the downstream industries, facilitate technology transfer from upstream companies, and periodically evaluate industrial estates.Keywords: agglomeration, downstream, productivity, spillover, upstream.Abstrak : Penelitian ini bertujuan untuk menganalisis pengaruh aglomerasi terhadap produktivitas perusahaan dari dua faktor penting aglomerasi, yaitu intraindustry (lokalisasi) dan crossindustry spillover (urbanisasi) dan mengkaji bagaimana pengaruhnya jika aglomerasi tersebut berasal dari industri upstream atau downstream dari perusahaan tersebut. Selain itu penelitian ini juga ingin membuktikan pengaruh jarak geografis dan jarak ekonomi terhadap kekuatan spillover. Dengan menggunakan data panel level perusahaan dari hasil survei industri besar dan sedang BPS untuk tingkat kabupaten kota dengan rentang waktu tahun 2008-2015 dan Tabel input output 2010 untuk melihat hubungan vertikal industri, diperoleh kesimpulan bahwa perusahaan menerima dampak spillover produktivitas yang positif dan signifikan dari berkumpulnya perusahaan dari sektor industri yang sama, maupun dari sektor industri lain yang berada di wilayah yang sama. Namun makin jauh jarak geografisnya, pengaruh tersebut semakin kecil. Spillover produktivitas juga diperoleh dari perusahaan sektor upstream dan downstream yang berkumpul diwilayah yang sama dengan perusahaan tersebut. Makin dekat jarak ekonominya makin besar pengaruh spillover dari sektor downstream. Pengaruh jarak ekonomi ini tidak ditemukan pada sektor upstream. Dengan demikian implikasi kebijakan dari hasil penelitian yaitu mendorong terciptanya hilirisasi industri, memfalitasi transfer teknologi dari perusahaan upstream, dan melakukan evaluasi kawasan industri secara berkala.Kata kunci: aglomerasi, downstream, produktivitas, spillover, upstream.

Abstract:
: The purpose of this study is to optimize service time in a community health center. The average number of patients visiting is 100 to 300 per day. In certain units there is a heavy queue of patients which increases service waiting times, including registration units, inspection units, and pharmaceutical units. The initial observation data on the existing system shows the waiting time for patient services is 2,7 hours. This fact shows that the time of patient service on the existing system needs to be optimized so that the waiting time can be accelerated. This study offers a solution to optimize the service queue system using a simulation approach. The DMAIC (Define, Measure, Analyze, Improve, Control) Six Sigma method is used as a basis for analyzing the waiting time for services from an existing system. The results of the analysis are used in the simulation test to obtain improvement factors using several scenarios. The best simulation results are obtained with the scenario of adding operators in all units. Optimizing the waiting time of patient services using the best scenario simulation approach is shown by the decrease in waiting time of the queue system by 1,05 hours or 38,9% faster than the existing system.Keywords: System Optimizing; Public Health; Queue; Simulation; DMAIC Six SigmaAbstrak : Tujuan penelitian ini adalah untuk mengoptimalkan waktu tunggu pelayanan di sebuah pusat kesehatan masyarakat (Puskesmas). Rata-rata jumlah pasien yang berkunjung adalah 100 hingga 300 per hari. Pada beberapa unit tertentu terjadi antrian pasien yang padat sehingga meningkatkan waktu tunggu pelayanan, antara lain unit pendaftaran, unit pemeriksaan, dan unit farmasi. Data pengamatan awal pada sistem yang ada menunjukkan waktu tunggu pelayanan pasien adalah 2,7 jam. Fakta ini menunjukkan bahwa waktu pelayanan pasien pada sistem yang ada perlu dioptimalkan agar waktu tunggu dapat dipercepat. Penelitian ini menawarkan solusi optimalisasi sistem antrian pelayanan dengan menggunakan pendekatan simulasi.

Abstract:
Indonesia has great potential in developing the furniture industry sector. The abundance of raw materials and high labor numbers should be optimized to encourage the furniture industry in Indonesia in the international furniture trade. However, in reality, the Indonesian furniture industry has increasingly been eliminated in the arena of international furniture trade. Therefore, it is necessary to consider how the furniture industry actually manages the company. One of the influential factors in furniture exports is how to manage the supply chain or logistics of the furniture industry, where one of them is related to the process of packaging and stuffing of furniture products. As a representation, this study tries to describe how the packaging and stuffing process is carried out by UD Surya Abadi Furniture, one of the furniture industries located in Sukoharjo Regency, Central Java. This research is a descriptive study, where data is collected by observation, interview, and documentation techniques. The results of this study discuss the packaging procedures, materials used and feasibility tests, and how the procedures and benefits obtained from the stuffing process at UD Surya Abadi Furniture. The conclusion obtained is that the description of the packaging and stuffing process that is carried out is quite good with the use of materials that meet the standards. Nevertheless, the process of packaging and stuffing at UD Surya Abadi Furniture is still done with manual counting so that it is not optimal.

Abstract:
Vendor Managed Inventory (VMI) is an approach in managing inventory between supplier and consumer in an supply chain system. In VMI concept, supplier keeps its inventory at consumer’s warehouse, meanwhile inventory ownership belong to supplier until it is used by consumer. The advantage of VMI is to reduce inventory replenishment ordering process and to reduce the usage of consumer’s warehouse space. Some key factors to achieve VMI success are: coordination, communication, production system and inventory order reliability.When supplier is a subsidiary of consumer, coordination between the two usually puts them not at an equivalent level, especially when supplier’s infrastructure is not as good as that at consumer. This research is a case study at a pharmaceutical company and its supplier which acts as its subsidiary. Information and data gathered by deep interview to all parties responsible for supply chain, production, and inventory at supplier and consumer sides. The results show advantages and obstacles in applying VMI, thus long-term commitment is needed to reach a better performance.
