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

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

Gardu Induk Tasikmalaya menyalurkan energi listrik tegangan menengah 20 kV melalui empat transformator, salah satunya Transformator V yang menyuplai Penyulang TNJG. Penyulang ini sering mengalami gangguan hubung singkat yang menyebabkan trip dan pemadaman, serta berpotensi memicu trip relay incoming 20 kV sehingga berdampak pada penyulang lain. Oleh karena itu, diperlukan koordinasi proteksi arus lebih (OCR) yang tepat antara sisi incoming dan penyulang. Analisis dilakukan melalui perhitungan arus hubung singkat sebagai dasar penentuan setting relay. Hasil perhitungan menunjukkan perbedaan dengan setting eksisting, di mana nilai TMS hasil perhitungan pada Penyulang TNJG sebesar 0,212 s dan incoming sebesar 0,27 s. Seluruh nilai masih memenuhi standar IEC 60255, dan hasil simulasi menunjukkan koordinasi proteksi telah bekerja dengan baik dan selektif.

Abstract

Meningkatnya kebutuhan energi listrik di Pulau Nusa Penida menyebabkan penurunan profil tegangan pada beberapa penyulang jaringan distribusi 20 kV sehingga diperlukan upaya untuk meningkatkan kualitas tegangan melalui integrasi Distributed Generation (DG). Berdasarkan Rencana Usaha Penyediaan Tenaga Listrik (RUPTL) 2025–2034, PT PLN (Persero) merencanakan pembangunan Pembangkit Listrik Tenaga Surya (PLTS) berkapasitas 4,5 MW sebagai DG di Nusa Penida. Namun, penempatan DG yang tidak tepat dapat mengakibatkan permasalahan seperti aliran daya balik dan ketidakstabilan tegangan. Penelitian ini bertujuan menganalisis kondisi profil tegangan sebelum penempatan DG, menentukan lokasi optimal penempatan DG menggunakan metode Voltage Sensitivity Index (VSI), serta menganalisis pengaruh penempatan DG terhadap perbaikan profil tegangan pada sistem distribusi 20 kV Nusa Penida. Penelitian dilakukan menggunakan perangkat lunak DIgSILENT PowerFactory melalui simulasi aliran daya (load flow analysis) dengan tahapan pemodelan sistem berdasarkan data aktual PT PLN (Persero), analisis kondisi eksisting, perhitungan VSI untuk menentukan lokasi optimal, serta pengujian variasi kapasitas DG sebesar 15%, 30%, 45%, 60%, 75%, dan 90% dari beban maksimum penyulang dengan total kapasitas tetap mengacu pada RUPTL sebesar 4,5 MW. Hasil penelitian menunjukkan bahwa penyulang Bunga Mekar, Ceningan, dan Ped merupakan penyulang yang mengalami penurunan profil tegangan paling signifikan. Berdasarkan perhitungan VSI diperoleh lokasi optimal penempatan DG yaitu pada Bus Bunga Mekar 1 dan Bus Bunga Mekar 2, Bus Ceningan 4, Bus Ceningan 5, Bus Ceningan 6, serta Bus Ped 3. Variasi kapasitas DG yang menghasilkan perbaikan profil tegangan terbaik adalah sebesar 75% pada Bus Bunga Mekar 1, 90% pada Bus Bunga Mekar 2, 90% pada Bus Ceningan 4, 90% pada Bus Ceningan 5, 45% pada Bus Ceningan 6, dan 90% pada Bus Ped 3 dengan total kapasitas 4,5 MW. Setelah penempatan DG pada lokasi dan kapasitas tersebut, profil tegangan pada seluruh bus yang dianalisis meningkat dan berada dalam batas standar operasi sistem distribusi sebesar 0,90–1,05 p.u. Hasil penelitian ini menunjukkan bahwa metode VSI efektif digunakan untuk menentukan lokasi optimal DG dan mampu meningkatkan kualitas profil tegangan di sistem distribusi 20 kV Nusa Penida, sehingga dapat menjadi referensi dalam pengembangan integrasi pembangkit energi terbarukan pada jaringan distribusi.
