Abstract

The regeneration process in saturated dehydrator after working to drying the gas in the dehydration unit in the Natural Gas Liquified Extraction (NGLE) plant. This process is through the heating dehydrator process by flowing the regeneration gas into the dehydrator slowly (rump up temperature) until it reaches the heating temperature,and then holding the condition. Its condition is in accordance with the engineering design and followed by a rump down temperature which the dehydrator will be cooled down and ready for the dehydration process. This regeneration process works automatically in accordance with the engineering design which runs following the logic control that has been implemented into the Distributed Control System (DCS) in the Control Room. All order in DCS to obtain gas that has been moisture limited value which is allowed to be extracted. Regeneration gas was taken from the heat exchange between hot oil and regeneration gas in the regeneration gas heater package. This operation happend when the rump up temperature leaks the hot oil in the flange fitting of the regeneration gas heater package, its causes oil spillage (engineering design standart operation procedur). Its analysis case assumed the leakage is caused by thermal shock in the fittings of regeneration gas heater package in 2 % hot oil supply. To eliminate the thermal shock, a simulation of new models engineering design is initial by opening of the hot oil supply to the regeneration gas heater was changes with increasing its opening during stand-by conditions from 2% with a temperature at 45.72°C to 5% with a temperature at 51.61C in the Distributed Control System (DCS) logic control. The results goals with this implementation are no more hot oil leaks occur in the regeneration gas heater package. New models engineering design is stopping hot oil spillage, and maintaining operational continuity without having to spend money on repairing the regeneration gas heater package. process run in new models of engineering design, and this model becomes the new standard operating in start-up and commissioning plant process.

Abstract

Pembangkit listrik tenaga pikohidro merupakan solusi energi terbarukan yang berpotensi besar untuk diterapkan di wilayah terpencil dengan sumber daya air yang melimpah. Salah satu tantangan utamanya adalah mendesain sistem yang efisien dan ekonomis. Dalam penelitian ini, alternator mobil digunakan sebagai komponen kunci yang dapat mengisi aki secara otomatis dan berhenti saat pengisian penuh. Alternator menghasilkan tegangan 12V yang disalurkan ke aki berkapasitas 45 watt, yang kemudian dialirkan ke inverter DC to AC 350 watt untuk menghasilkan listrik. Kecepatan turbin diukur menggunakan tachometer dan mencapai kecepatan stabil sebesar 186.9 rpm, dengan stabilitas debit air dijaga melalui penampang air. Metode penelitian mencakup desain sistem, implementasi, dan pengujian performa pembangkit. Hasil penelitian menunjukkan bahwa sistem ini dapat berfungsi dengan baik, menghasilkan listrik secara stabil, dan memenuhi kebutuhan daya dengan efisiensi yang memadai. Kesimpulannya, penggunaan alternator mobil dalam pembangkit listrik tenaga pikohidro adalah solusi yang efektif dan efisien, serta menjadi alternatif yang layak untuk pengembangan energi terbarukan di daerah terpencil. Penelitian ini memberikan kontribusi signifikan dalam pengembangan teknologi energi terbarukan dengan memanfaatkan komponen yang mudah didapatkan.

Abstract

This research introduces the design of a multifunctional animal feed chopper machine using a gasoline engine as the driving system. The gasoline engine used is Ecolite TE160 5.5 HP which can provide reliable power and performance to drive the feed chopper machine. The test material used is banana stems which are effectively finely chopper to obtain consistent and high quality chopper results. This design methodology includes identification of needs, mechanical design, material selection and testing of the tool. The working method of this machine is to insert the banana stem into the input hopper where the chopper knife rotates using a gasoline engine as the driving source. The chopper blade is specially designed with sharpness and thickness that suits the needs needed to get maximum and effective chopper results. The frame of this multifunctional animal feed chopper machine uses L 35 mm x 35 mm x 2.5 mm profile steel with a size of 105 cm long x 35.5 cm wide x 72.5 cm high. From the data obtained, the engine rotation used is 2500 Rpm. The results of testing this machine can be concluded that the heavier the material to be chopper, the longer the chopper time obtained, the thickness obtained is consistently 1.3 cm thick. Overall the development of a multifunctional animal feed chopper machine represents a significant advancement in pemp technology

Abstract

Gambir merupakan komoditi ekspor unggulan Sumatera Barat. Usahatani gambir banyak dilakukan desa-desa sentra pada Kabupupaten Lima Puluh dan Pesisir Selatan. Namun, desa-desa sentra tanaman gambir di Sumatera Barat jauh dari kota dan menyulitkan petani menjual produk ke konsumen. Ketergantungan petani pada pasar dan pengumpul desa sering merugikan petani akibat struktur pasar yang tidak sempurna. Solusi permasalahan tersebut adalah menjual produk gambir mereka secara online menggunakan teknologi internet. Penggunaan teknologi internet membantu manusia dalam mencari informasi, proses jual beli secara online dengan menggunakan media website. Melihat potensi, permasalahan serta pentingnya penggunaan website Universitas Muhammadiyah Sumatera Barat melakukan kegiatan pengabdian masyarakat kepada kelompok tani Ngalau Jaya (mitra) yang memproduksi gambir selama ini. Tujuan kegiatan agar kelompok tani jaya memiliki website penjualan dan dapat mengoperasikan website tersebut untuk mempromosikan dan memasarkan produk gambir mereka. Metode kegiatan berupa pembangunan website, pelatihan dan pendampingan kepada kelompok tani Ngalau Jaya. Hasil kegiatan menunjukan melalui pembuatan website mitra dapat mempromosikan dan menjual produk gambir mereka secara langsung (online) ke pembeli. Pelatihan dan pendampingan membuat mitra mengerti cara mengoperasikan website. Mitra telah dapat menginformasikan website dan produk mereka kepada masyarakat atau pembeli gambir. Promosi dan penjualan secara online meninkatkan penjualan produk mitra.

Abstract

One of the processed products derived from coconut that has great demand in the world of health and beauty industry is virgin coconut oil or known as VCO. Most VCO is processed manually using conventional methods with unhygienic plastic containers and placement in open spaces by the home industries. This research is to develop a VCO-fermented tank that was able to maintain hygiene and low temperature during the fermentation process by using SS403 and teak wood insulation as the main materials. This research carries on by comparing the fermentation process and results between the conventional method and the new VCO tank. 41% VCO is produced from raw coconut milk using a new VCO tank which is 5% higher than the conventional method. The VCO fermented tank produced more VCO and was able to maintain lower temperatures compared to the conventional method and also can be operated with less procedure order.     Keywords: Fermentation Tank, Temperature Retaine, VCO, Virgin Coconut Oil

Abstract

The coconut frond cutter or coconut frond shredder is a device used to transform coconut fronds into small pieces, even turning them into a finely textured material. This study examines the design and development of a coconut-chopping machine that uses an 8 HP combustion motor. Structural analysis was performed on the machine frame by considering the maximum and minimum Von Mises Stresses. The analysis results show that the maximum Von Mises Stress in the frame is 1.670e+06 N/mm², while the minimum stress is 2.338e+04 N/mm². The displacement of the frame was observed at 2.642e-02 mm to 1.000e-30 mm. The safety factor of the frame was found to be 1.366e+02, indicating an adequate level of safety. Next, this study analyzed the shredding capacity of the machine. The analysis showed that the largest shredding capacity was 3619.30 kg/hour, which occurred at a high rotation of young fronds, producing fine shreds. Meanwhile, the smallest shredding capacity of 612.66 kg/hour occurs at low rotation of old fronds and produces coarse shreds. These results provide essential insights into using coconut shredding machines based on the rotation level and the processed material. This research contributes to the development of efficient and effective coconut processing technology.
