Abstract

Papua province has nine small islands that are inhabited, but there is no access to electricity on these islands. The solution is the use of sea wind as a source of energy for a small power plant. This study aims to determine the potential of sea wind as an alternative source of electrical energy on the north coast of Papua Province. Data Measurement is carried out using an HP-866B anomometer on a hill near the coast to maximize the sea wind. There are two methods used in this research: the minimum-maximum value to determine the wind speed range and linear regression to determine the distribution pattern of the wind. The range of the sea wind is 0.2–6.18 m/s. If the minimum speed is limited to 1.6 m/s, then the range of kinetic energy is 5.59–322.22 Joules/s, mechanical power is 5.59–322.22 Watts, and actual power is 0.57–33.13 Watts. Meanwhile, the pattern shows that the sea wind from the north coast of Papua Province blows with two trends: constant and increasing, specifically in the afternoon and evening. Based on that, the development of a wind power plant on the north coast of Papua Province can be carried out using a multi-turbine system to increase the actual power that can be obtained.

Abstract

Pada penelitian terdahulu, alat pengering yang dianalisis adalah pengering surya dengan kolektor sekunder, rak bertingkat dan exhaust fan. Penelitian tersebut berhasil mengatasi fenomena lambatnya proses pengeringan akibat terperangkapnya uap air yang keluar dari sampel (tumpukan gabah) pada rak pengering bawah pada rak pengering tengah dan atas. Selain itu temperatur udara dalam kabin pengering sudah tidak melebihi 70oC sehingga kualitas produk (gabah) yang dikeringkan terjamin. Kekurangan pada alat pengering tersebut adalah exhaust fan yang digunakan membutuhkan supply energi listrik sehingga efisiensi pengering masih rendah. Untuk mengatasi kekurangan tersebut, maka pada penelitian ini akan dilakukan modifikasi dengan mengganti exhaust fan dengan turbin ventilator. Penelitian ini dilaksanakan di Laboratorium Teknik Mesin, Fakultas Teknik, Universitas Cenderawasih karena telah memiliki peralatan penunjang yang sudah memadai. Metode yang digunakan adalah metode eksperimen yakni membuat sebuah pengering surya tipe rak bertingkat (3 tingkat) dengan kolektor sekunder dan turbin ventilator. Kemudian dilakukan pengujian untuk mengetahui karakteristiknya. Hasil penelitian menunjukkan bahwa penambahan turbin ventilator merupakan solusi untuk mengatasi penggunaan energi listrik pada solar dryer. Proses pengeringan pada rak pengering 2 (tengah) dan 3 (atas) tetap berlangsung dengan cepat karena turbin ventilator bisa bekerja seperti exhaust fan. Laju aliran massa udara keluar dari pengering juga baik sehingga temperatur dalam kabin pengering tetap terjaga (tidak melebihi 70oC). Waktu pengeringan gabah dari kadar air awal 24,8% menjadi kadar air akhir 14% adalah 5 jam (rak 1); 6 jam (rak 2) dan 6 jam (rak 3). Efisiensi pengeringan maksimum yang diperoleh adalah 27,35% (rak 1); 24,05% (rak 2); 22,95% (rak 3); 24,78% (rata-rata).

Abstract

The type of drying device known as a hybrid dryer is a tool that harnesses solar energy and the heat generated by a biomass fuel-powered heat exchanger. This study was conducted to assess the performance of the hybrid dryer by analyzing the parameters of the device itself and the dried material. The research was carried out experimentally using a solar collector and a biomass furnace (as a heat exchanger) to heat the air. The solar collector used consists of 0.35 mm thick, black-painted zinc, coated with 5 mm thick glass, and installed at a 20-degree angle. The heat exchanger pipe used has a diameter of 1.25 inches and is made of galvanized pipe. The tested sample is corn seeds with an initial moisture content of about 24.6%. The experimental results show that in the drying process using a solar dryer, the initial moisture content of 24.8% was successfully reduced to 14% at 5.50 h (rack 1), 6.50 h (rack 2) and 7.00 h (rack 3) with a thermal efficiency of 24.25%. Meanwhile, in the hybrid drying process, the required time is approximately 5.00 h (rack 1), 5.50 h (rack 2) and 6.00 h (rack 3), with a efficiency of the drying equipment used is 21.048±5.690% (hybrid) and 22.706±6.437% (solar).

Abstract

Pompa sentrifugal merupakan mesin fluida yang paling banyak kita gunakan dalam kehidupan seharihari. Dalam pengoperasiannya terdapat banyak kerugian yang ditimbulkan oleh instalasi maupun konstruksi pompa itu sendiri. Telah banyak penelitian yang dilakukan untuk meminimalkan kerugiankerugian tersebut termasuk penelitian yang kami lakukan yaitu berupa modifikasi pada bagian inlet pompa sentrifugal. Penelitian ini bertujuan untuk mengetahui pengaruh pemasangan induser pada locknut impeller terhadap karakteristik pompa sentrifugal tipe aliran radial. Disini yang dimaksud dengan karakteristik pompa adalah head, debit, dan efisiensi pompa. Metode yang digunakan adalah eksperimen. Kegiatan yang dilaksanakan pada penelitian ini meliputi: perancangan dan perakitan alat pengujian pompa sederhana, pembuatan spesimen, pengambilan data, analisis dan pembahasan serta kesimpulan. Pada penelitian ini terdapat empat jenis pengujian, yakni: 1) Pompa sentrifugal tanpa modifikasi (normal); 2) Pompa modifikasi ke-1 dengan induser, panjang 25 mm; 3) Pompa modifikasi ke2 dengan induser, panjang 50 mm; dan 4) Pompa modifikasi ke-3 dengan induser, panjang 75 mm. Penelitian menunjukkan bahwa modifikasi dapat memperbaiki karakteristik pompa sentrifugal yang menjadi objek penelitian dimana terjadi peningkatan head total (Htot), debit (Q) dan efisiensi (ηp). Karakteristik terbaik yang diperoleh pada pompa modifikasi ke-2 dengan induser panjang 50 mm, disusuloleh pompa modifikasi ke-3 dengan induser panjang 75 mm, pompa modifikasi ke-1 dengan induser panjang 25 mm dan yang terendah adalah pompa tanpa modifikasi (normal). Karakteristik pompa sentrifugal Peningkatan tersebut disebabkan karena modifikasi dapat meminimalkan gejala pra-rotasi, turbulensi, serta pemisahan aliran. Atau dengan kata lain modifikasi menyebabkan terjadinya perbaikan pola aliran pada bagian inlet pompa sentrifugal.

Abstract

Corn cobs, an abundant agricultural waste, represent a promising alternative energy source when converted into briquettes. This study aimed to characterize corn cob briquettes and determine the optimal adhesive type and concentration for enhanced performance. Charcoal was produced from corn cobs via pyrolysis in repurposed oil drums, then ground and sieved through a 60-mesh screen. The resultant charcoal was combined with either starch or sago starch adhesives at concentrations of 7.5%, 10%, 12.5%, and 15% and subsequently molded into honeycomb briquettes using a 4-inch diameter mold with 16 perforations, fabricated from galvanized iron pipes and operated with a hydraulic jack. Proximate analysis indicated moisture levels of 5.37–6.71%, ash levels of 30.64–39.16%, volatile matter levels of 20.61–23.07%, fixed carbon proportions of 32.53–42.44%, and calorific values between 2893 and 3727 kcal/kg. A Water Boiling Test conducted with 1 liter of water demonstrated that briquettes incorporating 7.5% sago starch adhesive achieved boiling within 36 minutes, indicating superior combustion efficiency. These findings confirm the potential of corn cob briquettes as a renewable energy source and underscore the critical role of adhesive formulation in optimizing biomass fuel performance.

Abstract

This study investigates the viability of corn byproducts as an alternative energy source via conversion into honeycomb charcoal briquettes. Discarded corn byproducts are transformed into briquettes to mitigate fossil fuel reliance, particularly in the Arso region. This research aims to assess the energy output of briquettes with varying perforation configurations (4, 8, and 12 holes) and a diameter of 5 inches. The Water Boiling Test (WBT) method, utilizing temperature measurement tools such as a K-type thermocouple and an infrared thermometer, was utilized for performance assessment. One liter of water was heated to its boiling point during the experiment. The results indicated that the 8-hole briquette had the quickest boiling time of 25 minutes, with a fuel consumption rate of 2.8 × 10⁻³ kg/s. In comparison, the 4 and 12-hole briquettes required 35 minutes, with an average fuel usage of 2.86 g/s. The maximum combustion temperature for the 4-hole briquette was measured at 589°C, while the 12-hole briquette reached a mere 427°C. These outcomes demonstrate that the 8-hole briquette possesses superior efficiency. A decrease in hole quantity adversely affects boiling speed, while an increase in holes results in greater fuel consumption. These findings highlight the importance of optimized briquette design in improving biomass fuel efficiency.

Abstract

This community service activity aims to introduce biomass stoves to communities in need, particularly those with abundant biomass waste. The biomass stove's performance has already been evaluated through prior research conducted on campus. This community service initiative will be carried out with the Berkat Rama farmer group in Bibiosi Village, a major corn production area near Cenderawasih University in Arso District, Keerom Regency. Based on preliminary site assessments, local farmers reported significant quantities of agricultural waste, specifically corn cobs, left after harvest. This waste has not been optimally utilized by farmers and is typically disposed of by burning. Motivated by this, our community service team from the Department of Mechanical Engineering at Cenderawasih University aims to introduce corn cob-fueled biomass stoves to the local community. The Community Service Program (PKM) was met with strong enthusiasm from participants, who actively engaged in the socialization session through to its conclusion. The community expressed a desire for more frequent activities of this kind to broaden their knowledge and skills, especially regarding appropriate technology applications. The final outcome of this community service is an increase in both knowledge and skills among members of the Berkat Rama farmer group, specifically in the fabrication and operation of the introduced biomass stoves. They also received training in operational safety for biomass stoves. The acquired knowledge and skills are expected to be applied and shared with other community members and farmers in the area.
