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 increase in the area of agricultural land in Indonesia makes the need for fertilisers continue to increase. Compost is one type of natural organic that is widely known by farmers that comes from organic materials that undergo weathering processes due to interactions between microorganisms (decaying bacteria) that work in it. Elephant grass is one of the plants that can be used as compost and has enormous potential. The existing elephant grass chopping machine still uses a serrated blade. So that the chopping cannot be chopped properly. In this study, the elephant grass chopping machine will be modified into an elephant grass chopping machine that uses HSS (High Speed Steel) material blades and the machine is driven by a 1 hp electric motor. The purpose of this research is to change the elephant grass chopping machine with HSS (High Speed Steel) blades and to make cutting faster. The research method used is experimental research using the French method and the Reverse Enginering Method The design process of the elephant grass chopping machine uses the Solidwork application. The test material used is 1000gr for one test. The resulting average is perfectly chopped as much as 897 gr, not perfectly chopped as much as 17.7 gr left / in the tube 84 gr, with a time of 60.08 seconds. The production capacity of the machine is 56.06 kg/hour. The machine that has been made is able to chop elephant grass with product efficiency.

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.

Abstract

Bamboo processing is one of the activities in the home industry in many rural areas. Currently, bamboo craftsmen in Indonesia still slice and chop bamboo manually. The process of slicing and chopping bamboo manually often faces problems, including poor production quality. Modifying the bamboo splitting machine by adding slicing and chopping functions aims to increase the production efficiency of bamboo processing for skewer production and make the machine more optimal and multifunctional. The modification of the bamboo splitting machine with additional functions as a slicing and chopping machine uses two blades, namely a slicing blade designed to thin the bamboo to 3-4 mm and a chopping blade to chop or split the bamboo into several small sticks with a square profile of 3-4 mm, and an input hopper that adjusts to the average width of the test material. The results of bamboo slicing using the machine obtained 2 to 3 slices that meet the desired size, and the rest are residual slices that do not meet the desired size from one bamboo split. The results of bamboo chopping using the machine obtained 3 to 4 chopped bamboo that meet the desired size, and a few residual chopped bamboo that do not meet the size and defective chopped bamboo due to the bamboo entering the input hopper in a tilted position. The production capacity of the bamboo slicer is 1,816 slices/hour, and the production capacity of the bamboo chopper is 7,513 sticks/hour.

Abstract

Sahabat Farm adalah kelompok swadaya masyarakat (KSM) sebagai pengelola rumah maggot. Namun pengelolaan pakan maggot yang berkualitas dengan biaya terjangkau masih menjadi kendala dalam pengembangan budidaya maggot seperti yang dialami Sahabat Farm Bangka Belitung. KSM mengolah bahan pakan maggot dari limbah kulit jeruk secara manual membutuhkan waktu 60 menit untuk 30 kg limbah kulit jeruk. Kebutuhan pakan maggot 120 kg/hari tidak efektif jika dilakukan pembuburan kulit secara manual. Berdasarkan diskusi langsung dengan KSM Sahabat Farm, mereka membutuhkan mesin yang dapat mencacah kulit jeruk menjadi halus (pembuburan) sebagai pakan maggot. KSM Sahabat Farm mampu menghasilkan 60 kg per hari maggot dengan total 1,8 ton per bulan. 1 kg maggot membutuhkan 2 kg limbah organik. Sehingga, untuk memberi makan 60 kg maggot dibutuhkan 120 kg limbah organik perharinya. Tim pengabdian akan membuat mesin pembubur kulit jeruk dengan kapasitas mencapai 170 kg/jam. Maggot digunakan mitra sebagai pakan ikan, pakan unggas, dan dijual ke konsumen mendapatkan benefit yang menopang ekonomi keluarga. Melalui proposal pengabdian ini, tim pengabdian akan membuat dan menyerahkan mesin pembubur kulit jeruk ke mitra dan melakukan pendampingan penggunaan mesin. dengan mesin tersebut, diharapkan dapat meningkatkan produktiftivas mitra dalam memproduksi maggot

Abstract

Jurusan Teknik Mesin pada tahun 2024 telah melaksanakan melaksanakan pengabdian kepada masyarakat di desa Pergam Kecamatan Airgegas Kabupaten Bangka Selatan. Mitra pengabdian adalah Pemberdayaan Kesejahteraan Keluarga (PKK) Desa Pergam. Untuk lanjutan pengabdian tahun 2025 berdasarkan hasil wawancara dengan bapak Sukardi (kepala desa pergam) dan Ibu Nenih Sumarni (ketua PKK desa Pergam) adalah tentang pembuatan kompos. Saat ini dibutuhkan alat atau mesin untuk membantu dalam produksi kompos. Kendala saat ini yang dialami mitra yaitu pencacahan bahan-bahan untuk kompos masih dilakukan secara tradisional menggunakan pisau atau parang. Selain itu pengadukan untuk mencampur bahan kompos masih dilakukan secara manual sehingga memerlukan tenaga yang besar dan waktu yang cukup lama. untuk mencacah bahan kompos bisanya diperlukan waktu berkisar 30 menit sehingga tidak efektif. Tim pengabdian berencana membantu mitra dengan menyiapkan mesin pencacah bahan organik. Mesin yang akan dihibahkan merupakan mesin dari hasil penelitian mahasiswa program studi Teknik Mesin. Mesin tersebut diharapkan dapat digunakan untuk mencacah bahan-bahan organik untuk bahan pembuatan pupuk kompos. Melalui proposal pengabdian ini, tim pengabdian akan membuat dan menyerahkan mesin pencacah sampah organik ke mitra, melakukan pendampingan penggunaan mesin, dan sosialisasi cara membuat pupuk kompos.
