Abstract

Era Industri 4.0 telah membawa perubahan dalam segala aspek kehidupan, termasuk dalam bidang teknologi Militer. Saat ini telah diperkenalkan beberapa teknologi militer seperti sistem tanpa awak dan sistem robot kolaboratif dengan Big Data yang mampu mendeteksi ancaman dan serangan musuh. Meski merupakan negara yang kaya akan sumber daya alam, Indonesia tidak lepas dari konflik bersenjata. Papua menjadi wilayah dengan kejadian konflik bersenjata tertinggi di Indonesia. Organisasi Papua Merdeka (KKB) diklaim berada di balik setiap penyerangan yang terjadi. Penyerangan yang dilakukan KKB tidak hanya merugikan warga sipil, namun juga personel TNI dan Polri serta posko TNI dan Satpam. Kurangnya teknologi khusus di pos-pos militer dan penjagaan mengakibatkan ketergantungan pada kewaspadaan personel yang bertugas untuk mengantisipasi serangan. Berdasarkan situasi tersebut, penulis bertujuan untuk memperkenalkan robot penjaga yang dapat diterapkan di pos militer di Papua. Robot penjaga yang diusulkan dilengkapi dengan senjata SS7 dan terintegrasi dengan kamera yang memungkinkannya mengenali teman atau musuh. Proses mengenali kawan atau lawan mengimplementasikan pengolahan citra. Hasil pengenalan akan dikirimkan ke layar di pos militer melalui pengirim video

Abstract

This study aims to develop a prototype braking system for wind turbines used in wind power plants by utilizing a dummy load resistor. The background of this research is the necessity for an effective braking system to control the speed of wind turbines, especially under extreme wind conditions, which can cause damage to the system and electrical components. The designed braking system uses a dummy load resistor to reduce the rotational speed of the turbine by dissipating excess electrical energy as heat. Tests were conducted to evaluate the effectiveness of the system under various wind conditions and to measure performance parameters such as turbine speed stability and protection of electrical components. The results show that the uses of dummy load resistors are effective in diverting excess voltage with a set point of 14 volts, and at 300 rpm using voltage sensors, proximity sensor and MOSFETs as voltage control, which will be diverted to the dummy load resistor system. Thus, this research makes a significant contribution to the development of wind power technology, particularly in terms of safety and operational efficiency.

Abstract

Micro-hydro Power Plant is a small-scale power plant. Micro-hydro plants are built with enough water potential to generate electrical energy. A common problem with micro-hydro generating systems is that the output of the generator is not constant. This is caused by changes in connected loads. Thus causing frequent fluctuations in the frequency and voltage of the system that can cause damage to electrical equipment. Because it is used Load Frequency Control (LFC) to control the frequency can be more stable. To obtain optimal control parameters on micro hydropower systems used by Artificial Intelligence (AI) is Adaptive Neuro-Fuzzy Inference System (ANFIS). ANFIS data is retrieved from training data of PID controllers tuned using Ant Colony Optimization (ACO) and Bat Algorithm (BA). This study compared uncontrolled methods, PID-ZN control methods, PID-ACO method, PID-BA, PID-ACO-ANFIS, and PID-BA-ANFIS obtained the best control method. The result of this research is the control method of PID-ACO-ANFIS is the best control method with overshoot 0.00 and the fastest settling time is 0.00. The results showed that the smallest overshoot (0) in the PID-ACO-ANFIS model, the smallest undershoots (1,12x10-5) in PID-ACO-ANFIS and the fastest settling time (3.77 seconds) in the starting also at PID-ACO-ANFIS. The results of this study will be tried bengan other methods, which results may be better

Abstract

Konflik bersenjata di Papua yang sering terjadi membuat Papua berpredikat nomor 1 paling banyak terjadi konflik bersenjata di Wilayah Indonesia. Banyak orang mengklaim bahwa pelaku utama disetiap konflik bersenjata yang telah terjadi di Papua adalah Kelompok Kriminal Bersenjata (KKB). KKB sering melakukan aksi teror terhadap warga. Tidak hanya warga disekitar, namun juga para Personel TNI dan POLRI yang bertugas di Papua tidak luput dari serangan KKB. Terkadang Serangan KKB juga mentargetkan Pos Militer atau Pos Jaga. Kondisi Pos jaga yang belum terdapat teknologi apapun membuat serangan yang dilancarkan oleh KKB sulit diantisipasi. Jika terjadi serangan yang mentargetkan Pos, antisipasi serangan mengandalkan kesigapan personel yang bertugas. Kondisi ini dirasa perlu untuk menghadirkan teknologi dalam mengantisipasi serangan pada Pos Jaga. Penulis berkeinginan menghadirkan robot penjaga sebagai jawaban atas permasalahan yang terjadi. Robot penjaga yang diusulkan ini terintegrasikan dengan senjata SS2. Tembakan dari robot penjaga dapat dikendali secara jarak jauh. Kendali jarak jauh dari robot tersebut mengimplementasikan modul Lora Sx1278 yang diklaim dapat menjangkau hingga 500 meter. Hasil dari penelitian ini adalah banyaknya data memberikan pengaruh terhadap delay pengiriman. Delay terendah pada pengujian ke 10 dengan data yang dikirim sebanyak 10 kata dengan rata-rata delay dari 10x pengujian adalah 531 ms, sedangkan delay terendah pada pengujian ke 1 dengan data yang dikirim sebanyak 1 kata dengan rata-rata delay dari 10x pengujian adalah 81 ms. Pada pengujian Jarak pengiriman data pada modul lora SX1278 pada kondisi LOS menghasilkan jarak terbaik sebesar 350 meter, sedangkan pada kondisi NLOS pada jarak 100 meter.

Abstract

One of the conductors of water flow is an open channel, which we often encounter for irrigation and drainage purposes. Flow velocity (V) in an open channel depends on several parameters, namely longitudinal slope, cross-sectional geometric elements and obstacles that occur along the channel. Longitudinal slopes and geometric elements can be directly measured in the field or planned. The resistance value varies greatly depending on several factors, for example the material used for the body of the channel and other obstacles such as the presence of vegetation along the channel (vegetation). The resistance value in the channel is expressed by a resistance coefficient number such as the Chezy, Strickler and Manning resistance coefficient. This research aims to determine the resistance coefficient value in open channels, which is influenced by vegetation. The channel roughness coefficient used is the Manning roughness coefficient (n). Observations were carried out on a prototype open channel made from river stone masonry with dimensions of base width = 0.3 m, height = 0.5 m and channel slope = 1 : 1 with vegetation variations of 0%, 25%, 50%, 75%, and 100% of the channel length. Flow velocity was measured using a Currentmeter with 5 measurements for each variation in vegetation percentage. From the results of the analysis and changes, it was found that there was a slowdown in the flow velocity along with an increase in the percentage of vegetation relative to the length of the channel. For normal channels/without vegetation, the value "n" = 0.025 is obtained which corresponds to Manning's "n" value for stone masonry channels. Meanwhile, for the percentage of growth of 25%, 50%, 75% and 100%, there is an increase in the "n" value respectively as follows; 0.031, 0.043, 0.058, and 0.062
