Analisa data nilai pH buah anggur menggunakan SPSS 24 yaitu uji kruskal wallis. Berdasarkan hasil analisa data didapat bahwa medan magnet ELF intensitas 300μT dan 500μT berpengaruh terhadap nilai pH buah anggur hitam. Nilai pH kelompok kontrol lebih tinggi dari kelompok eksperimen. Hal ini disebabkan karena intensitas di bawah 500μT menekan pertumbuhan mikroorganisme pembentuk asam didalam buah angggur hitam. Kata kunci: medan magnet ELF; analisa data; pH. ABSTRACTThe ELF magnetic field is an electromagnetic wave with a frequency of up to 300 Hz and is classified as non-ionizing radiation. This study used a randomized subject post-test only control group design, with the division of two groups of research subjects randomly selected. This study aims to determine the effect of exposure to ELF magnetic fields on the pH value of black grapes. In this study, there were two groups, namely the control and experimental groups, where the experimental group was treated with an ELF magnetic field with an intensity of 300μT and 500μT for 60 'and 120' for each intensity. The data analysis of the pH value of grapes used SPSS 24, namely the kruskal wallis test. Based on the results of data analysis, it was found that the ELF magnetic field with the intensity of 300μT and 500μT had an effect on the pH value of black grapes. The pH value of the control group was higher than the experimental group. This is because the intensity below 500μT suppresses the growth of acid-forming microorganisms in the black grapefruit.

Abstract:
ABSTRAKPandemi Covid-19 telah memberikan dampak yang signifikan dalam dunia pendidikan. Dampak pandemi Covid-19 ini menuntut peserta didik maupun pendidik untuk dapat beradaptasi dalam melakukan pembelajaran jarak jauh. Pada prosesnya, pembelajaran jarak jauh masih dianggap kurang efisien dalam pelaksanaannya terutama pada proses transfer materi ajar. Akibatnya banyak peserta didik yang mengabaikan pembelajaran. Salah satu upaya mengatasi permasalahan tersebut adalah dengan dilakukan pemilihan model dan metode pembelajaran yang sesuai dengan kondisi saat ini, sehingga perangkat pembelajaran yang digunakan perlu dilakukan pengembangan sebelum digunakan. Penelitian ini menggunakan jenis penelitian Research and Development (R&D) dengan model 4D yang terdiri dari empat tahapan yaitu Define, Design, Develop, dan Disseminate. Perangkat yang dikembangkan pada penelitian ini adalah silabus, RPP, LKPD, dan instrumen tes kemampuan generik sains. Kevalidan perangkat yang dikembangkan diperoleh berdasarkan validitas dari enam validator yaitu tiga validator ahli dan tiga validator praktisi, kemudian kevalidan perangkat dianalisis dengan menggunakan skala Likert. Selanjutnya, keefisienan perangkat ditentukan dari respon peserta didik dan respon guru. Berdasarkan hasil penelitian yang telah dilakukan, diperoleh nilai rata-rata validitas diatas 3.26 dengan kategori sangat baik. Pembelajaran daring yang dilakukan berdasarkan respon peserta didik menunjukkan bahwa peserta didik kurang puas sehingga pembelajaran daring yang dilakukan kurang efisien hal tersebut dikarenakan adanya beberapa kendala salah satunya adalah keterbatasan kuota internet peserta didik. Maka dapat disimpulkan perangkat pembelajaran fisika model berbasis masalah pada materi elastisitas valid tetapi kurang efisien untuk digunakan dalam pembelajaran daring. Kata kunci: perangkat pembelajaran, pembelajaran berbasis masalah, generik sains. ABSTRACTThe Covid-19 pandemic has had a significant impact on the world of education. The impact of the Covid-19 pandemic requires students and educators to be able to adapt in doing distance learning. In the process, distance learning is still considered inefficient in its implementation, especially in the process of transferring teaching materials. As a result, many students ignore learning. One of the efforts to overcome this problem is by selecting a learning model and method that is in accordance with the current conditions, so that the learning tools used need to be developed before use. This study uses a Research and Development (R&D) type of research with a 4D model consisting of four stages, namely Define, Design, Develop, and Disseminate. The tools developed in this study were the syllabus, lesson plans, student worksheet, and generic science proficiency test instruments. The validity of the developed device was obtained based on the validity of six validators, namely three expert validators and three practitioner validators, then the validity of the devices was analyzed using a Likert scale. Furthermore, the efficiency of the device is determined from the responses of students and teacher responses. Based on the results of the research that has been done, the average value of validity is above 3.26 with the very good category. Online learning that is carried out based on the responses of students shows that students are not satisfied so that online learning is not efficient because there are several obstacles, one of which is the limited internet quota of students. So it can be concluded that problem-based model physics learning tools on elasticity material are valid but less efficient for use in online learning. Keywords: learning tools, problem-based learning, generic science.

Abstract:
Development is to make nature an object of tourism exploitation, shifting to a culture-based tourism development model (halal tourism) and nature conservation (eco-tourism). As a national mainstay tourism area, NTB has a beautiful culture and nature as a tourist attraction, so the concept of sharia tourism has begun to be applied in NTB, but ecotourism has only just been initiated by the NTB provincial government. One of the problems that have slowed the progress of the ecotourism model is the absence of legal instruments as the basis for ecotourism policy in NTB. Discusses the government's legal policies in accommodating ecotourism development and the legal policy model of the NTB provincial government. The type of normative legal research and the approach method is the statutory approach. The study results show that, first, the Government's legal policies in efforts to develop ecotourism in the context of statutory regulations have provided guidelines for local governments that have ecotourism potential to develop optimally by providing several incentives and facilities for ecotourism actors. Second, the NTB provincial government legal policy model supporting ecotourism is to create a legal basis for policies in the form of provincial regional regulations on environment-based tourism through indications of regional tourism development programs that be stipulated in a Regional Long-Term Development Plan.Keyword: Legal Policy; Ecotourism; NTB Province.

Abstract:
During this pandemic, many aspects felt the impact of COVID 19, the economic aspect. Many companies have experienced losses from closing to bankruptcy and even bankruptcy. There are several ways that debtors can do so that they do not go bankrupt, one of which is by postponing debt payment obligations (PKPU). Therefore the author raises issues related to the delaying payment scheme for debtors' debt obligations to creditors during the pandemic. The research methodology is normative juridical because, in this problem, there are empty norms. Using a statue approach, a case approach, a historical approach, a comparative approach, and a conceptual approach. Data analysis techniques are descriptive techniques, interpretation techniques, evaluation techniques, and argumentation techniques. The results show that PKPU will result in restructuring, while bankruptcy will end in settlement (sale and asset distribution) of the debtor. PKPU is not intended for the benefit of the debtor only but also for the creditor's interest. PKPU is a deliberation between debtors and creditors to find the best solution for both, which the court supervises. The debtor can improve his financial position and submit a peace plan to pay off the debt. Therefore, it is hoped that the implementation of PKPU can help companies avoid the word bankruptcy and rise from the downturn caused by COVID 19.Keyword: Bankrupt; PKPU; Covid 19. ABSTRAKPada masa pandemi ini begitu banyak aspek yang merasakan dampak dari COVID 19 ini, salah satunya aspek ekonomi. Banyak perusahaan yang mengalami kerugian dari tutup hingga gulung tikar bahkan pailit. Ada beberapa cara yang dapat dilakukan debitur agar tidak pailit yaitu salah satunya dengan melakukan penundaan kewajiban pembayaran utang (PKPU), oleh sebab itu penulis mengangkat permasalahan terkait skema penundaan pembayaran kewajiban hutang debitur kepada kreditur dimasa pandemi. Metodologi penelitian adalah yuridis normatif, karena dalam permasalahan ini terdapat norma kosong. Menggunakan pendekatan Undang-Undang (statue approach), pendekatan kasus (case approach), pendekatan historis (historical approach), pendekatan komparatif (comparative approach), dan pendekatan konseptual (conceptual approach). Teknik analisis data yaitu dengan teknik deskripsi, teknik interprestasi, teknik evaluasi, dan teknik argumentasi. Hasil penelitian bahwa, PKPU akan menghasilkan restrukturisasi, sedangkan kepailitan akan berakhir pada pemberesan (penjualan dan pembagian asset) debitur. PKPU tidak dimaksudkan untuk kepentingan debitur saja, melainkan juga kepentingan kreditur. PKPU merupakan musyawarah antara debitur dengan kreditur untuk mencari solusi terbaik bagi keduanya, yang diawasi oleh pengadilan, sehingga debitur mampu memperbaiki posisi keuangannya dan mengajukan rencana perdamaian untuk membayar hutang. Oleh karena itu, diharapkan dengan dilakukannya PKPU dapat membantu perusahaan terhindar dari kata pailit dan dapat bangkit dari keterpurukan yang disebabkan oleh COVID 19 ini.

Abstract:
Air is an inseparable part of a country, a country's sovereignty over land and sea also means sovereignty over airspace. As an international community, it is only natural that Indonesia's airspace is used for the common interest of supporting population mobility and economic improvement. However, Indonesian sovereignty over airspace is still being violated by foreign aircraft. Air Defence Identification Zone (ADIZ) is a zone for identification of foreign aircraft before entering the airspace. The determination of ADIZ Indonesia needs to be accompanied by various preparations including improving positive laws regarding airspace security, completing air defense system infrastructure, and building an understanding of the concept of ADIZ Indonesia with neighboring countries directly bordering Indonesia. This paper uses a normative legal research method using a descriptive analysis approach, a legal material search technique uses a secondary data source obtained through a literature study, and a study analysis uses qualitative analysis. The results of the writing show that there are legal gaps and gaps in the determination of administrative sanctions fines, the lack of the number of radars belonging to the Indonesian Air Force under the National Defense Force in protecting Indonesian airspace, and the heavy-duty of the Ministry of Foreign Affairs to build the trust of neighboring countries amid the dynamics of the South China Sea territorial conflict if the government determines ADIZ Indonesia.Keywords: Airspace; Sovereignty; ADIZ. ABSTRAKUdara merupakan bagian yang tidak terpisahkan dari suatu negara, kedaulatan suatu negara akan daratan dan lautan juga berarti kedaulatan akan wilayah udara. Sebagai masyarakat Internasional, sudah sewajarnya wilayah udara Indonesia dimanfaatkan untuk kepentingan bersama guna mendukung mobilitas penduduk sampai peningkatan ekonomi. Namun kedaulatan Indonesia akan wilayah udara masih marak dilanggar oleh pesawat udara asing. Air Defence Identification Zone (ADIZ) merupakan zona identifikasi pesawat udara asing sebelum memasuki wilayah udara. Penetapan ADIZ Indonesia perlu dibarengi dengan pelbagai kesiapan meliputi penyempurnaan hukum positif mengenai pengamanan wilayah udara, melengkapi infrastruktur sistem pertahanan udara, dan membangun kesepahaman konsep ADIZ Indonesia dengan negara tetangga yang berbatasan langsung dengan Indonesia. Menggunakan metode penelitian hukum normatif dengan menggunakan pendekatan deskriptif analisis. Teknik penelusuran bahan hukum menggunakan sumber data sekunder yang didapat melalui studi kepustakaan. Analisis kajian menggunakan analisis kualitatif. Hasil penulisan menunjukan bahwa ada celah dan kekosongan hukum dalam penetapan denda sanksi administratif, kurangnya jumlah radar milik TNI AU dibawah Kohanudnas dalam melindungi wilayah udara Indonesia, dan tugas berat Kementerian Luar Negeri untuk membangun kepercayaan negara tetangga ditengah dinamika konflik teritorial Laut China Selatan apabila pemerintah menetapkan ADIZ Indonesia.

Abstract:
The development of law in Indonesia is determined by the political configuration between the legislature and the executive. Nearly 85 percent of the People's Representative Council tends to close or qualify with the executive. When the executive submits draft legislation, it is immediately approved by the Indonesian Parliament. The urgency of the research is to determine the influence of politics on the formation of law in Indonesia. What is the political configuration and character of Indonesian legal products and their re-actualization and formulation? The research method used is normative research through library research and a statutory approach. The research shows that currently, in Indonesia, the political dominance of the law is getting stronger. A political party that should be the incarnation of the people's will only appear to be a vehicle to gain or maintain power. This results in legal products produced only by political interests and certain groups, without paying attention to their suitability with the objectives of the State. The historical movement of the transition of Islamic law in Indonesia is full of various historical, philosophical, political, sociological, and juridical dimensions. In fact, Islamic law in Indonesia has fluctuated in line with the politics of law practiced by state authorities. This is based on the socio-cultural strength of the majority of the Muslim community in Indonesia. There is interaction in terms of political decisions, thus giving rise to various political decisions to benefit the Islamic community itself. In Indonesia, there is a determinant politics of law. This means that law is a variable that is influenced by politics. The situation and the political policies that took place greatly influenced the Islamic community's attitudes.Keywords: Politics; Law; Indonesia. ABSTRAKPerkembangan hukum di Indonesia ditentukan oleh konfigurasi politik yang terjadi antara legislatif dan eksekutif. Kecenderungan Dewan Perwakilan Rakyat hampir 85 persen merapat atau berkualisi dengan eksekutif, sehingga ketika eksekutif mengajukan draf perundang-undangan langsung di setujui DPR RI. Urgensi penelitian untuk mengetahui pengaruh politik terhadap pembentukan hukum di Indonesia. Bagaimana konfigurasi politik dan karakter produk hukum Indonesia, dan reaktualisasi dan formulasinya. Metode penelitian yang digunakan adalah penelitian normatif, melalui penelitian kepustakaan dan pendekatan perundang-undangan. Hasil penelitian, bahwa saat ini di Indonesia, dominasi politik terhadap hukum semakin menguat. Partai politik yang seharusnya menjadi penjelmaan kehendak rakyat, hanya terkesan menjadi kendaraan untuk memperoleh maupun mempertahankan kekuasaan. Hal ini berakibat pada produk hukum yang dihasilkan hanya sesuai dengan kepentingan-kepentingan politik dan golongan tertentu, tanpa memperhatikan kesesuaiannya dengan tujuan Negara. Pergerakan sejarah peralihan hukum Islam di Indonesia, penuh dengan berbagai macam dimensi historis, filosofis, politik, sosiologis dan yuridis. Faktanya, hukum Islam di Indonesia telah naik turun sejalan dengan politik hukum yang di praktekan oleh penguasa negara. Hal tersebut besumber pada kekuatan sosial budaya mayoritas masyarakat Islam di Indonesia. Adanya Interaksi dalam hal putusan politik, sehingga memunculkan berbagai keputusan politik bagi kepentingan masyarakat Islam itu sendiri. Di Indonesia terjadi politik determinan atas hukum. Artinya bahwa hukum adalah variabel yang terpengaruhi oleh politik. Situasi dan kebijakan politik yang berlangsung sangat mempengaruhi sikap yang harus di ambil oleh masyarakat Islam.

Abstract:
The aim of this research is to find the difficulties of students in solving word problems in the three-variable linear equation systems subject. Before they took a mathematical problem-solving exam, the learners were given reinforcement of prerequisite knowledge of the intended subject. The problem-solving test indicators used in this study were taken from Polya's problem-solving steps consisting of (1) recognizing the question, (2) making a plan for problem-solving (developing a plan), (3) implementing the plan for problem-solving, and (4) looking back. The research method used in this study was a qualitative descriptive. The subject in this study was 15 students who were 10 th graders of senior high school. The data were obtained from a student performance who took mathematical problems solving test. The result obtained from this study can be seen from the number of students whose achievement indicators formulate a plan of 49.6%, achievement in completing plans 14.1%, and achievement in checking solutions 2.2%. However, the indicators of understanding the problem area in the good category, namely 80%. The result of this study showed that the students were only able to solve the word problems for understanding the problem (good category) and devising the plan steps (mediocre category), whereas they got difficulties in solving the word problems in carrying out the plan and looking back (low category).

Abstract:
Mathematics is seen by some students as a subject which is not easy to learn. Thus, they need someone who can make mathematics easy, in this point, a teacher. Teachers as instructor are needed to be more innovative in developing instruction that can encourage students to get an ideal learning experience. Not just regarding approaches, teaching materials, and strategies, yet additionally needs to focus on the learning environment which promotes the learning process. One of the framework that offers learning which takes into a supportive learning environment is the Productive Pedagogies Framework. The purpose of this study is to look at the implementation of learning that utilized the Supportive Classroom Environment dimension of the Productive Pedagogies Framework. This study used qualitative method. There were 33 grade VII students (boys and girls) on average age of 13 years old from one of the Junior High Schools in Bandung participated in this study. The research findings revealed that (1) implementing Supportive Classroom Environment can further encourage students in upper group to achieve more optimal learning outcomes; (2) This learning can be said to encourage middle group students to get optimal learning outcomes; (3) This learning has not been able to encourage students in lower group. We concluded that implementing Supportive Classroom Environment can further encourage students in upper and middle groups.

Abstract:
Many students in the world have difficulty in solving word problems, including students in Indonesia. TIMSS has shown that only eight percent of Indonesian participants are able to solve word problems, this result is hugely lower than the international average of 18 percent. One of the factors that cause students' errors in solving word problems is mathematical resilience. Thus, this study aims to analyze students' misconceptions in solving word problems viewed by their mathematical strength. This study was conducted for sixth-grade students in one of the elementary schools in Bandung. This study was qualitative descriptive research. In this study, there were four steps: selecting the word problems, answering the issues, filling out a mathematical resilience questionnaire, and interviewing. Students were encouraged to respond to a three-word question within 30 minutes, filling out a mathematical resilience questionnaire followed by the interview. This study showed that the students' errors in solving word problems were including comprehension, transformation, and process skill errors. Based on mathematical resilience, students with a low level of resilience predominantly carried out comprehension errors. In contrast, students with a moderate level of resilience more dominant made transformation errors. Meanwhile, students with high resilience completed more questions correctly, although several students seemed to have made process skills errors. This study's limitation is the data obtained online so that the respondents completed the instrument exceeds the given time. Further researches are suggested to conduct directly in the classroom to maximize the accuracy of the study.

Abstract:
Sentiment analysis is an analysis with an objective to identify like, dislike, comments, opinion, or feedback on certain content which will be categorized into positive, negative, or neutral. In general selection, sentiment analysis widely known to be used to predict the winner on election process. This method tries to dig the people sentiment on their governor candidates during election, whether it’s positive, negative, or neutral opinion. The output of the positive sentiment is related to people acceptance towards one of the election nominee. That statement usually applied as a base reference for determining the result of the election process. In sentiment analysis, the importance of its fuzzy logics must be considered. Each of the people statement is assumed to have the level of positive, negative, or neutral percentage. The concept of fuzzy logic is developed and applied on one of this text mining method. This research is focusing on comparison analysis and fuzzy logic application in sentiment analysis method. Two method which discussed in this research are Fuzzy Naïve Bayes and Sentiment Fuzzy with convolutional neural network. This research is applied on PILKADA of Solo and Medan district case study. The data of the people opinion are acquired from twitter and collected on September 2020 to December 2020. The two methods which mentioned before are implemented on the acquired data and the output of these method application then compared. The conclusion of this research suggest that different approach will resulting in different output.

Abstract:
Investment can be defined as an activity to postpone consumption at the present time with the aim to obtain maximum profits in the future. However, the greater the benefits, the greater the risk. For that we need a way to predict how much the risk will be borne. Modelling data that experiences heteroscedasticity and asymmetricity can use the Asymmetric Power Autoregressive Conditional Heteroscedasticity (APARCH) model. This research discusses the time series data risk analysis using the Value at Risk-Asymmetric Power Autoregressive Conditional Heteroscedasticity (VaR-APARCH) model using the daily closing price data of Bitcoin USD period January 1 2019 to 31 December 2019. The best APARCH model was chosen based on the value of Akaike's Information Criterion (AIC). From the analysis results obtained the best model, namely ARIMA (6,1,1) and APARCH (1,1) with the risk of loss in the initial investment of IDR 100,000,000 in the next day IDR 26,617,000. The results of this study can be used as additional information and apply knowledge about the risk of investing in Bitcoin with the VaR-APARCH model.

Abstract:
The research purpose shown in this article is describing the time dependent reproduction number of coronavirus called by COVID-19 in the new normal period for 3 types areas, i.e. small, medium and global areas by considering the number of people in these areas. It is known that in early June 2020, Indonesia has claimed to open activities during the pandemic with the new normal system. Though the number of COVID-19 cases is still increasing in almost infected areas, normal activities are coming back with healty care protocols where public areas are opened as usual with certain restrictions. In order to have observations of spreading impact of COVID-19, the basic reproduction number (Ro) i.e. the reproduction number (Ro) is the ratio between 2 parameters of SIR model where SIR stands for Susceptible individuals, Infected individuals, and Recovered individuals respectively. The reproduction numbers are computed as discrete values depending on time. The used research method is finite difference scheme for computing rate of change parameters in SIR models based on the COVID-19 cases in Indonesia (global area), Jakarta (medium area) and Salatiga (small area) by considering the number of people in these areas respectively. The simple forward finite difference is employed to the SIR model to have time dependent of parameters. The second approach is using the governing linear system to obtain the values of parameter daily. These parameters are computed for each day such that the values of Ro are obtained as function of time. The research result shows that 3 types areas give the same profiles of parameters that the rate of changes of reproduction numbers are decreasing with respect to time. This concludes that the reproduction numbers are most likely decreasing.

Abstract:
Creativity is very necessary for learning mathematics, especially when solving geometry problems. This research aims to describe 4th year mathematics education students’ creativity in solving geometry problems. Creativity in this research is focused on fluency, flexibility, and originality of student anwer when solving geometry problems. This research is an explorative descriptive research through a qualitative approach. The participants were 7 fourth year mathematics education students of state University in Mataram, who have a high level of visual-spatial intelligence. The data was collected by written test and interview. The test consisted of two open-ended geometry problems about transforming 3-dimensional images into 2-dimensional images and making 2-dimensional images with a predetermined circumference. The problems are modification of the 2006 PISA test. The result showed that subjects with high visual-spatial intelligence levels met all indicators of creativity. In solving problems that meet the aspects of fluency, flexibility and originality, they combine mental rotation and mental visualization abilities and include using their visual experience by modifying the information obtained and the initial problem solving ideas obtained. This also enables them to produce original problem solutions. The results of this research can be used as an illustration and a guideline to assess students’ creativity with high visual-spatial intelligence level.

Abstract:
This research aims to obtain optimal value for the surface roughness of the material AISI P20 on the Electrical Discharge Machining (EDM) Sinking process. In the present research, the Taguchi method is used to investigate the significant influence of process variables on the machining performance and determine the combination of process variables on the EDM process. Orthogonal array L18 (21 × 33) based on the Taguchi method is chosen for the design of experiment. The experiment is replicated twice to finding out the influence of four process variables such as type of electrode, voltage gap, on-time, and off-time on the response performance. Machining performance is evaluated by surface roughness as a response variable that had quality characteristics, smaller is better. These experimental data were analyzed using the Signal-to-noise ratio and Analysis of Variance. The analysis results show that the surface roughness is influenced by the type of electrode and on time. Combination of process variables to obtain optimal surface roughness are using graphite electrodes, and setting values of gap voltage 40 volt, on-time 250 μs, and off-time 20 μs. This combination of process variables can be applied to the manufacturing process using EDM sinking in order to produce a good quality product that determined based on the surface roughness value.

Abstract:
In this paper, we studied a mathematical model of tuberculosis with vaccination for the treatment of tuberculosis. We considered an in-host tuberculosis model that described the interaction between Macrophages and Mycobacterium tuberculosis and investigated the effect of vaccination treatments on uninfected macrophages. Optimal control is applied to show the optimal vaccination and effective strategies to control the disease. The optimal control formula is obtained using the Hamiltonian function and Pontryagin's maximum principle. Finally, we perform numerical simulations to support the analytical results. The results suggest that control or vaccination is required if the maximal transmission of infection rate at which macrophages became infected is large.
