Abstract

The location of the Community Service Program for the Food Security Scheme is in Kec. Kawalu, Tasikmalaya City which is 8 km from Siliwangi University. One of the livelihoods of the residents of Kec. Kawalu is a broiler breeder and has five breeders. The partners of this activity are micro and small breeder companies, namly Sejahtera Mandiri and Maju Bersama and they have been operating for more than two years. The number of employees who are members of the companies of Prosperous Mandiri and Maju breeders together are 4 and 5 people, respectively. In one maintenance period, the business group raises an average of 2000 chicks per cage. The period of rearing chickens until harvest is 30-35 days. During the brooding period (the period when chicks still need brooders or need heating until they are 15 days old), the breeders provide heating facilities with wood/rice husk fuel heaters. Monitoring the cage climate such as temperature and air quality is done manually with conventional temperature and air quality measuring instruments or by observing the activity and distribution of chicks approaching/away from the heater. The problem faced by partners is that there are still many broiler breeders who do not pay attention to the condition of the chickens for monitoring temperature and air quality on a regular basis, causing a high mortality rate of broiler chickens. The purpose of this activity is to increase the knowledge, insight and skills of the broiler breeder community in the district. Kawalu in using automatic control devices and monitoring the temperature and air quality of the cage remotely. The number of participants is 5 people from members of the broiler breeder group UMK Sejahtera Mandiri and Maju together in Lewiliang Village, Kec. Kawalu, the city of Tasikmalaya. The training will be held from 29 to 30 September 2022. This activity is carried out using training, practice, and mentoring methods. The training method is to provide material on procedures for using automatic temperature monitoring control devices and ammonia gas (derived from chicken manure). The practical method is carried out by practicing automatic temperature monitoring tools and ammonia gas. The results of the training showed that the participants' interest in this activity was categorized as very good, especially for the aspect of effectiveness and practicality of broiler chicken coop climate control tools in realizing community empowerment.

Abstract

Kec. Cibalong, Kab. Tasikmalaya is 32 km from Siliwangi University and has manganese ore deposits. Kec. Cibalong has smallholder manganese ore mining with the management carried out by local. Two micro and small scale mining companies (UMK), namely the Bara Abadi and Mangan Jaya Companies as partners for community service activities and are local companies that accommodate and facilitate the marketing of people's manganese ore mining products. Both companies have an average of ten workers as miners. During the manganese ore exploration process, it generates residual waste in the form of manganese ore tailings from leaching. Estimates based on information made by the two partners indicate that for every tonne of manganese ore produced, two tonnes of manganese ore tailings are removed. Based on current production levels, it can be estimated that approximately 1,200 tonnes of manganese ore mine tailings are produced annually in Setiawaras Village. These manganese ore tailings are abandoned on roadsides, reservoirs, vacant lots and mining areas. The problems faced by partners are (1) the accumulation of manganese ore mine tailings disturbs and narrows the land for manganese ore mining activities, (2) manganese ore mining tailings causes soil and groundwater pollution, (3) limited knowledge and skills of partners in processing manganese ore tailings products into quality printed roof tiles, (4) limited equipment for the production process of molded bricks from manganese ore mine tailings. The objectives of this program are (1) to increase the added value of manganese ore mining tailings through downstream processing of tailings into molded roof tiles for building materials, (2) to increase the knowledge, insight and skills of the partners group in the manufacture of molded roof tiles without burning from manganese ore mine tailings, and (3) equip production equipment to convert manganese ore mine tailings into molded tile products. The number of participants was 5 members of the Bara Abadi and Mangan Jaya companies in Setiawaras Village. The training was held from 24 to 25 September 2022. This activity is carried out using training, practice, and mentoring methods. The training method is to provide materials on the procedures for making printed roof tiles from a mixture of manganese tailings and plastic waste adhesive. The practical method is carried out by practicing the preparation of fine manganese tailings, adhesive from plastic waste, heating a mixture of manganese tailings and plastic waste using a drum, molding dough with tile molds. The results of the training showed that the participants' interest in this activity was very good, especially for the aspects of tile printing, practicality, and community empowerment. From the aspect of operating activities, it indicated that participants could use and operate the tile printer independently without assistance.

Abstract

Distributed photovoltaic (PV) generation has emerged as a key solution for enhancing the performance of medium-voltage (MV) distribution networks, particularly in isolated systems with limited conventional generation. This study investigates the impact of centralized and distributed PV integration on voltage profile and power losses in the 20 kV East Sumba distribution system. A steady-state load flow analysis using the Newton–Raphson method was performed in DIgSILENT PowerFactory under three PV penetration levels (20%, 50%, and 100% of peak load). The base-case condition shows significant undervoltage at remote buses and total active power losses of 474.47 kW, mainly due to long radial feeders and concentrated loading. The results indicate that centralized PV placement yields the strongest voltage recovery near the interconnection point at 100% penetration, whereas the minimum system power loss is achieved at 50% penetration. By contrast, distributed PV placement provides more uniform voltage support across remote buses, although with lower effectiveness in reducing total system losses. These findings reveal a clear operational trade-off between voltage improvement and loss minimization, implying that the preferred PV placement strategy should be selected according to the specific technical objective of the network. This study provides practical insights for planning and optimizing PV integration in weak and isolated MV distribution systems.

Abstract

The insulation condition of high-voltage equipment can be determined by measuring partial discharge (PD), which is an important indicator in insulation degradation. One of the PD detection methods that can be used is to use antennas as sensors in detecting electromagnetic waves generated from PD activities, especially in gas insulated switchgear (GIS) systems. This study focuses on designing and testing dipole antennas in the ultra-high frequency (UHF) frequency range of 300 Mhz-3 GHz to detect PD signals in GIS. Previous studies on dipole antennas with dimensions of 66×15 mm have reported a bandwidth of 336 MHz and a return loss of -22.4 dB at 1.3 GHz. The antenna was fabricated using an FR4-epoxy substrate with a thickness of 1.6 mm, a substrate radius of 102 mm, and a gap distance of 2 mm. Optimization of the antenna length and width significantly improved performance characteristics. Simulation results show that a dipole antenna with dimensions of 35×40 mm antenna produced a wider bandwidth of 989 MHz with a return loss of −28.47 dB at 1.4 GHz. Experimental validation using vector network analyzer (VNA) and PD testing on GIS confirmed that the optimized dipole antenna effectively detected PD activity at a voltage level of 16 kV.

Abstract

Kebutuhan energi listrik nasional terus meningkat seiring pertumbuhan penduduk dan industrialisasi. PLTU menjadi salah satu sumber utama energi listrik di Indonesia, akan tetapi PLTU menghasilkan emisi gas buang, khususnya sulfur dioksida (SO₂), yang berbahaya bagi lingkungan. Salah satu upaya pengurangan emisi adalah penerapan teknologi Circulating Fluidized Bed (CFB) dengan penambahan batu kapur (CaCO₃) sebagai agen penangkap sulfur. Penelitian ini bertujuan untuk menganalisis pengaruh variasi rasio campuran batu bara dan batu kapur terhadap efisiensi energi dan output daya listrik pada sistem PLTU berbasis CFB. Simulasi dilakukan dengan MATLAB Simulink menggunakan variasi rasio 100:0, 90:10, 85:15, 80:20, dan 70:30, serta efisiensi boiler antara 0,84–0,90. Hasil penelitian menunjukkan bahwa penambahan batu kapur menurunkan daya keluaran akibat sifat endotermik batu kapur, namun mampu menekan emisi SO₂ hingga lebih dari 80%.
