Dalam menghadapi jenis ancaman peperangan masa depan dengan tren teknologi Internet of Military Things (IoMT) dan Internet of Battlefield Things (IoBT) diperlukan pengadaan jenis alutsista yang sesuai meningkatkan keamanan nasional dibidang autonomus weapon jenis Unmanned Aerial Vehicle (UAV) yaitu loiteringmunition. Teknologi kunci dari loiteringmunition sendiri terdiri dari guidance, navigation, dan control system. Tiga teknologi ini yang membuat loiteringmunition bergerak secara otomatis dan sistem akuisisi target dibantu dengan teknologi Artificial Intelligent (AI). Agar manfaat program pengadaan loiteringmunition dapat dilaksanakan secara optimal oleh lembaga pemerintah Indonesia, perlu adanya strategi. Strategi optimalisasi pengadaan loiteringmunition yang dapat dilakukan melalui Forward Engineering, Reverse Engineering, kerja sama produksi/lisensi atau pengadaan dari luar negeri, sehingga nantinya mampu menciptakan kemandirian industri pertahanan dalam negeri. Berdasarkan analisa kelebihan dan kekurangan masing-masing strategi dan perhitungan skala prioritas menggunakan metode Simple Additive Weighting (SAW) maka dapat diambil keputusan berdasarkan skala prioritas dengan menempatkan strategi kerja sama produksi/lisensi sebagai prioritas utama dan dapat dijadikan strategi Indonesia dalam percepatan penguasaan teknologi loiteringmunition dan mampu menciptakan kemandirian industri pertahanan dalam negeri.

Estimasi sumberdaya merupakan bagian penting dalam eksplorasi bahan galian. Tujuan penelitian ini adalah melakukan perhitungan volume dan tonase batubara menggunakan metode USGS Circular. Kondisi geologi dianggap sederhana karena aspek tektonik yang tidak signifikan dilapangan, sehingga jarak titik informasi yang digunakan yaitu 500 meter (terukur), 1.000 meter (tertunjuk), 1.500 meter (tereka). Perhitungan sumberdaya dimulai dari cropline sampai batas ijin konsesi atau batas poligon daerah pengaruh terluar, dan dari hasil penelitian ditemukan arah sebaran seam batubara dari barat kearah timur dan arah kemiringan dominan ke selatan. Berdasarkan hasil penelitian diketahui bahwa estimasi volume dan tonase dengan metode USGS Circular untuk estimasi sumberdaya terukur dan tertunjuk Seam 1.000 adalah 2,07 juta m³ dan 2,7 juta ton (terukur), 3,8 juta m³ dan 5,02 juta ton (tertunjuk), 5,8 juta m³ dan 7,5 juta ton (tereka).

Kupang city, as the representative of East Nusa Tenggara Province, is the first most populous city in the province with the density of 63 peoples/km. It is the centre of trading, government, education, and other typical urban activities within the province. However, the unintegrated drainage system and the high level of land conversion has caused several sub-districts in Kupang city become prone to flooding. This research aims to map the flood-prone locations based on Geographic Information System by exploring thematic maps (rainfall, estimation of seawater inundation, historical of flooding, distance from river, slope, land aquifer, and land use) which can visualize flood zone in Kupang city. The result of this study indicates that Kelapa Lima is the most flood-prone sub-district compared to others, due to the dominance of settlement density, trade in services, and the existence of primary arterial road access which are not supported by an optimal irrigation.

Gudang atau warehouse berperan penting dalam sistem logistik suatu industri atau perusahaan. Namun demikian, pengetahuan tentang healthcare warehouse yang telah dikembangkan dalam beberapa tahun terakhir masih kurang. Untuk itu, maka artikel ini menyajikan integrated literature review pertama tentang healthcare warehouse melalui pencarian di penyimpanan dari basis data Scopus. Dengan menelusuri setiap artikel terkait dengan topik tersebut, didapatkan 24 artikel yang diterbitkan dari tahun 2013-2022 dan diklasifikasikan menjadi dua topik utama: goods warehouse sebanyak 4 artikel, dengan fokus healthcare yang terdapat pada fasilitas kesehatan, dan data warehouse sebanyak 20 artikel, yang memiliki fokus pada healthcare berisi berbagai jenis data, contohnya rekam medis, barang, dan data penyakit tertentu. Semua pengetahuan yang ada dalam studi ini dirangkum sehingga pembaca (baik akademisi maupun praktisi) dapat dengan mudah mengakses kontribusi utama dan informasi yang ada dalam setiap studi.

Biomass co-firing technology is one way to accelerate the transition to renewable energy in Indonesia. Co-firing is currently used for the mixed combustion of coal and biomass in steam power plants with a certain blending ratio. One of the PLTU’s that has implemented co-firing technology in Indonesia is PLTU XYZ. However, as the co-firing technology progresses, PLTU XYZ experiences a number of problems, both in technical and non-technical areas. This study aims to evaluate the most appropriate co-firing technology that can be used for PLTU XYZ. The method used in this study is the Analytical Hierarchy Process (AHP). The results of this study indicate that the most effective criteria are economic and environmental, with weights of (0.4383) and (0.3024) followed by technical (0.1904) and social (0.0689). The most appropriate biomass co-firing technology currently used for PLTU XYZ is direct co-firing with the highest weight (0.7080) followed by indirect co-firing (0.1753) and parallel co-firing (0.1165).

Unmanned aerial vehicle (uav) merupakan wahana udara tanpa awak yang dikendalikan dari jarak jauh. Pemanfaatan wahana udara tanpa awak ini salah satunya sebagai media pemantauan yang memiliki keunggulan pada nilai efektifitas kerjanya. Untuk melakukan pengamatan daerah perkotaan diperlukan rancangan pesawat uav yang dapat lepas landas dan mendarat secara vertikal (vtol) dan memiliki kecepatan tinggi dalam melakukan perpindahan dari satu tempat ke tempat yang lainnya. Tahap pertama dalam perancangan pesawat vtol uav ini adalah menentukan geometri pesawat sesuai kriteria yang telah ditentukan, kemudian dilakukan pemodelan dan analisis aerodinamik dengan menggunakan software solidwork. Hasil rancangan pesawat memiliki panjang fuselage 1,1849 meter, wing span 3 meter, dan berat 5,9 kg. Hasil analisis aerodinamik diperoleh CLmax sebesar 0,363125 pada sudut serang 4^o, nilai CDmax sebesar 0,199722 pada sudut serang 4^o, dan nilai efisiensi max sebesar 1,81815 pada sudut serang 4⁰.

Software testing in the field of software engineering is a life cycle process within a software project that verifies that the product or service meets quality expectations and validates that the software meets specifications and requirements. Software testing is intended to find defects in a program The growing complexity of today's software systems results in an increased need for sophisticated testing techniques. Performing software testing activities manually appears to be ineffective in terms of labor consumption, which demands a low speed of execution. and inadequate test coverage. In order to overcome this problem, an automated testing approach is needed with one of the methods that can be used, namely boundary value analysis combined with equivalence partitions, so that it can help the process of making test case scenarios. The input is invalid, so the application that is made still needs improvement.

Pollutant dispersion modeling in around Yogyakarta International Airport wasconducted using AERMOD software. There is a strong positive correlation between the number of aircraft and land transportation and the number of pollutants considered. The ambient air quality at the study site for all pollutants originating from the landing and take-off (LTO) cycle is still below quality standards, but for those sourced from the combination of the LTO cycle and land transport traffic for NO2 pollutants exceed the quality standard, while for CO and hydrocarbon pollutants it is still below quality standards.
