Abstract

Breeding ducks has several advantages, including: 1) the stages of raising ducks are easier; growth period; 2) duck growth is much faster, need 40 days to harvest; 3) marketing of meat and egg crops is easier; and 4) you can sell other parts to ducks, duck feathers for crafts and their droppings can be used as catfish feed. For laying ducks, their eggs can be harvested when they are 5 to 7 months old. Breeding ducks promises big enough profits that one of the livestock groups "Taret Jaya" has been raising broiler ducks since 2022. The community service partner is the Taret Jaya livestock group, located in Air Anyir village, Merawang sub-district, Bangka Regency. Based on the results of the survey to partner locations, there were several partner problems, including: manual counting of ingredients, limited knowledge of duck feed mixture ingredients, limited knowledge in making duck feed (fermentation process), and the mixing process in making feed was still manual. Currently, partners chop the feed ingredients using machetes and stir the feed ingredients using a hoe. The ingredients that have been stirred are then directly given to the ducks without going through a fermentation process. Through community service at this department level, the service team provides a solution that is offered in the form of a duck feed mixer machine. Mixing time with 50-60 kg of mixed material using a machine is 6 times faster than manually, namely around 5 minutes, compared to manual which takes 30 minutes. The service team has handed over to service partners, among other things: one unit of feed mixing machine, DOD duck seeds, feed making materials, and other supporting equipment for raising livestock. With this machine, partners can increase their livestock productivity.

Abstract

Stoves have experienced developments from time to time. One of the stove developments is a multifuel stove which is a type of stove that can use many types of fuel as fuel. Multifuel stoves have many important components that function to support the combustion process, one of which is the stove nozzle which functions to flow air into the combustion tube. In this study, tests will be conducted to find out the effect of variations in the diameter of the stove nozzle holes on the characteristics of the fire and water temperature during the water heating process. The method used in this test is a combination of experimental studies and literature studies. There are 5 variations of nozzle hole diameter that will be tested, namely 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, and 3.5 mm. The fuel used is used cooking oil. The desired fire characteristic is the longest flame length. The results of the tests that have been carried out are based on the highest average fire temperature is 716°C found in nozzles with a hole diameter of 2.5 mm, and the lowest average fire temperature is 557°C found in nozzles with a hole diameter of 1.5 mm. The longest flame duration was 1,295 seconds at the nozzle hole diameter of 1.5 mm, while the fastest flame duration was 832 seconds at the nozzle hole diameter of 3.5 mm. The variation of nozzle hole diameter has no effect on the color of the flame, which produces a blue color with a yellowish flame tongue. The longest water boiling time was 180 seconds for nozzle hole diameters of 1.5 mm, 3.0 mm, and 3.5 mm, while the fastest water boiling time was 150 seconds for nozzle hole diameters of 2.0 mm and 2.5 mm.

Abstract

The purpose of this study was to examine the implementation of the School Literacy Movement (SLM) as well as its challenges in high schools in Bangka Belitung. The study combined a descriptive method with a qualitative approach. Principals, instructors, librarians, and a number of student representatives from grades X through XII from three schools in Kab. Bangka Barat were the subjects of this study. In order to gather data for this study, observation, interviews, and documentation were used. The study's findings demonstrated that the SLM program had not been executed at SMA/MA in Kab. Bangka Barat in the most effective way possible. This was evident from the inadequate preparatory phase, which prevented the SLM program from being implemented to its full potential. The implementation of this SLM remained hampered by a number of challenges, according to this study. These included students' low reading interest, the school's limited supply of reading materials, its lack of time to give students reading assignments, and its inconsistent application. Also, it had not been shown how important parents of students were to the success of this program.

Abstract

Penggunaan bahan alami untuk menghasilkan biokomposit ramah lingkungan telah menjadi tren dalam beberapa tahun terakhir, dengan salah satu fokus utama pada polivinil alkohol (PVA). PVA dianggap sebagai pilihan potensial untuk plastik ramah lingkungan karena dapat terurai secara alami. Namun, harga PVA yang relatif tinggi mendorong pengembangan biokomposit yang diperkuat dengan serat alami untuk menurunkan biaya dan meningkatkan kekuatan. Penelitian ini mengeksplorasi penggunaan Phytoplankton sebagai bahan penguat dalam biokomposit PVA. Phytoplankton, yang kaya akan protein, dikenal sebagai bioindikator kualitas air dan memiliki potensi besar sebagai bahan baku biopolimer untuk plastik ramah lingkungan. Hasil penelitian menunjukkan bahwa penambahan Phytoplankton dapat mempengaruhi serapan air pada biokomposit. Pada PVA murni, serapan air meningkat secara konsisten dari 1,35% pada 30 menit hingga 8,90% pada 450 menit. Namun, penambahan Phytoplankton, baik 10 ml, 20 ml, maupun 30 ml, menyebabkan penurunan serapan air, dengan penurunan paling signifikan pada 30 ml. Hal ini mengindikasikan bahwa semakin banyak penambahan Phytoplankton, semakin rendah kapasitas serapan air PVA. Penelitian ini memberikan wawasan baru mengenai potensi Phytoplankton sebagai bahan penguat biokomposit dalam pengembangan plastik ramah lingkungan yang lebih efisien dan berkelanjutan.

Abstract

Desa Pergam merupakan salah satu desa yang terletak di Kecamatan Air Gegas Kabupaten Bangka Selatan Provinsi Bangka Belitung dengan luas wilayah 176,36 km2. Mata pencaharian penduduk antara lain sebagai petani, penambang, wiraswasta, pedagang, buruh bangunan, nelayan, dan ASN. Potensi desa Pergam sangat banyak, salah satunya adalah kerajinan tangan, anyaman berbahan bambu. Berdasarkan diskusi dengan calon mitra pengabdian, ketua PKK Desa Pergam, dan Kepala Desa Pergam didapatkan beberapa permasalahan mitra pengrajin anyaman bambu dalam menjalankan usahanya, antara lain: 1) pemotongan bambu dilakukan dengan gergaji secara manual; 2) pembelahan bambu dilakukan secara konvensional menggunakan golok; 3) mengiratkan bambu dilakukan secara konvensional menggunakan pisau. Diantara tiga permasalahan tersebut, proses yang paling rumit adalah mengirat bambu. Untuk mengiratkan satu ruas bambu berukuran panjang sekitar 80 cm memerlukan waktu 60 menit dan menghasilkan sekitar 50 lembar bahan anyaman. Proses ini tidak efsiensi karena memerlukan waktu yang cukup lama. Berdasarkan uraian diatas, mitra pengabdian mengusulkan pemanfaatan mesin irat bambu untuk meningkatkan produktivitas usaha mereka. Tim pengabdian kepada masyarakat prodi Teknik Mesin telah menyerahkan satu unit mesin irat bambu, yang diserahkan langsung kepada kepala Desa Pergam. Mesin tersebut mampu mengirat bambu berkisar 30 s.d 35 lembar dalam waktu 1 menit. Penggunaan mesin irat bambu lebih efisien dibandingkan dengan cara konvensional sehingga dapat meningkatkan produktivitas produk anyaman bambu.

Abstract

Elvira EV-1, as an electric vehicle (EVs) has become one of the latest developments that contributes to achieving sustainable and reliable transportation. These EVs were built to serve as a relevant solution for campus operational mobility. However, at the core of its framework system, Elvira EV-1 still uses a ladder-type chassis, which is inferior to other types of chassis in terms of torsional rigidity. Therefore, to enhance its mechanical performance, this study determined the best option of beam cross-section for the Elvira EV-1 chassis. There were three types of the selected beam section, namely rectangular, I-beam, and C-channel. The mechanical performance of each type of chassis was examined using the Frame Analysis module provided by Autodesk Inventor. The results show that the rectangular chassis experienced the highest bending stress of the other types of chassis due to its low moment of inertia, which is almost 26.27% higher. Nonetheless, with the same setup, the shear stress that occurred at the C-channel type of chassis was greater than its material. The chassis would fail under the load subjected to it. Similarly, I-beam chassis has the maximum torsional stress greater than the yield strength of the material due to low torsional rigidity. In addition, the mass of the chassis with rectangular section provided a more lightweight structure, about 36,92% lower than the other type of chassis. According to these findings, it can be concluded that the chassis with a rectangular section has promising performance to be an option as the Elvira EV-1 chassis.

Abstract

Multifuel stove is an innovation of conventional stove that has the advantage of being able to use various types of fuel. In its operation, multifuel stove consists of many important components, one of which is the combustion tube. This study aims to find out the effect of variations in the diameter of the combustion tube on the characteristics of the flame and water temperature during the heating process. The method used in this study is a combination of experimental studies and literature studies. The variations in the diameter of the combustion tube tested were 4, 5, and 6 inches using used oil and kerosene as fuel. The test results showed that increasing the diameter of the combustion tube tended to accelerate the extinguishing of the fire, this was influenced by a phenomenon called the quenching effect. Meanwhile, the flame temperature tended to be lower with increasing tube diameter. The color of the flame and the temperature of the water were not too influenced by variations in tube diameter and type of fuel. The highest flame temperature was recorded on a 4-inch cylinder with used oil fuel, reaching 719.2 °C, while the longest flame duration was 16.92 minutes on a 4 -inch cylinder with used oil fuel. In conclusion, the performance of used oil can exceed that of kerosene.
