ABSTRAKDesa Mentaras Kecamatan Dukun Kabupaten Gresik merupakan salah satu sentral pertanian dan peternakan di kabupaten Gresik. Salah satu mata pencaharian yang ditekuni penduduk adalah beternak sapi dan kambing. Pakan memegang peranan yang sangat penting dalam rantai produksi peternakan. Masalah yang dialami peternak desa mentaras yakni proses penyajian pakan kepada ternak biasanya dilakukan secara langsung, tanpa perlakuan atau manipulasi sebelumnya. Hal ini dapat mengurangi efisiensi dalam penggunaan pakan hijauan. Penyajian pakan tersebut cenderung menghasilkan sisa makanan karena tidak habis dimakan maupun jatuh ke tanah. Kegiatan ini bertujuan untuk memberikan solusi pengolahan pakan ternak untuk mengatasi permasalahan yang dihadapi masyarakat Desa Mentaras. Metode pengabdian masyarakat ini adalah membuat mesin cacah rumput yang digunakan untuk mencacah rumput pakan ternak baik rumput basah maupun rumput kering. Setelah mesin tersebut selesai, kemudian dilakukan workshop penggunaan mesin untuk mencapai tujuan yang telah direncanakan. Hasil dari pengabdian ini diwujudkanlah mesin sesuai dengan konsep desain. Mesin ini menggunakan motor listrik berdaya 1 Hp dan mempunyai kecepatan putar motor 1420 RPM. Kapasitas produksi mesin ini yakni 100 kg/jam untuk pencacahan rumput basah dan 70 Kg/jam untuk pencacahan rumput kering. Dengan adanya mesin ini maka rumput ternak telah tercacah dengan ukuran 3-4 cm dan dapat ditambahkan bahan lainnya guna menambah gizi ternak, sehingga lebih sehat dan gemuk. Kata kunci: mesin cacah; pakan ternak; ternak. ABSTRACTMentaras Village, Dukun District, Gresik Regency is one of the centers of agriculture and animal husbandry in Gresik Regency. One of the livelihoods occupied by residents is raising cows and goats. Feed plays a very important role in the livestock production chain. The problem experienced by farmers in Mentaras village is that the process of serving feed to livestock is usually done directly, without any previous treatment or manipulation. This can reduce efficiency in the use of forage feeds. The presentation of the feed tends to produce food residue because it is not eaten or falls to the ground. This activity aims to provide solutions for animal feed processing to overcome the problems faced by the Mentaras Village community. This community service method is to make a grass chopper machine that is used to chop animal feed grass, both wet grass and dry grass. After the machine is finished, then a workshop on the use of the machine is carried out to achieve the planned goals. The result of this service is that the machine is realized according to the design concept. This machine uses an electric motor with a power of 1 HP and has a motor rotation speed of 1420 RPM. The production capacity of this machine is 100 kg/hour for chopping wet grass and 70 kg/hour for chopping dry grass. With this machine, the livestock grass has been chopped with a size of 3-4 cm and other ingredients can be added to increase the nutrition of the livestock, making it healthier and fatter. keywords: chopping machine; animal feed; livestock

The ignition system is a system that greatly affects the performance of a vehicle. Capacity Discharge Ignition (CDI) is a component in the ignition system that works to set the right ignition timing, therefore combustion can be maximized. This study aimed to compare the use of a factory CDI with a CDI from another vehicle, namely the 110 cc Shogun, to determine the performance of a 125 cc GL Max motorbike including torque, power, and fuel consumption to efficiency. The data collection was carried out at speeds of 25 km/hour to 65 km/hour for each gear with an increase of 10 km/hour. The results showed that the larger the gear or teeth, the value of torque, power, and efficiency will also increase. The best results were obtained in the 110 cc Shogun CDI variation with respective values of 7.96 Nm, 6.8 pk, and 81.14%. Meanwhile, the value of the most economical fuel consumption is still the standard CDI GL Max 125 cc with a value of 0.12 kg/pk.hour in the highest gear.

Pelton turbines are impulse turbines widely used in micro-hydro power systems operating under high-head and low-flow conditions. Their performance depends strongly on the quality of the water jet impacting the runner buckets, which is influenced by nozzle distance and valve opening. This study experimentally investigated the effects of nozzle distance (60, 70, and 80 mm) and valve opening (30°, 60°, and 90°) on the hydraulic power, turbine power, electrical power, and efficiency of a laboratory-scale Pelton turbine. Turbine rotational speed was measured using a tachometer, while voltage and current were measured using a multimeter to determine power output. The results showed that increasing the valve opening increased hydraulic, turbine, and electrical power due to higher flow rate and jet kinetic energy. However, the turbine efficiency showed non-linear behavior because it was influenced by the quality of the jet and the effectiveness of momentum transfer. The maximum turbine power of 10.52 Watts and electrical power of 10.58 Watts were obtained at a nozzle spacing of 80 mm and a valve opening of 90°. Meanwhile, optimum efficiency was achieved at a nozzle distance of 80 mm and a valve opening of 30%, indicating that optimum conditions do not always occur at maximum flow. The results of this study indicate that the combination of nozzle distance and valve opening significantly influences Pelton turbine performance and is important for optimizing laboratory-scale micro-hydro systems.

Wind energy is a potential renewable energy source in Indonesia, but the relatively low wind speed requires efficient turbine technology. The Savonius turbine has become an alternative choice for generating electrical energy. This research aims to determine the performance of the Savonius type-S turbine with blade numbers of 3, 5, and 7 at different wind speeds. The method used was an experiment conducted in a laboratory-scale wind tunnel simulator, with testing conducted across three blade configurations at wind speeds of 6, 7, and 8 m/s. The research results show that the 3-blade turbine achieves optimal torque at all wind speeds, with a maximum of 0.24 Nm at 8 m/s. The maximum wind power is obtained with the 7-blade turbine, reaching 167 watts at 8 m/s. The optimal turbine power also occurs with the 3-blade configuration, with the highest value being 10.30 watts at 8 m/s. The highest turbine efficiency is achieved by the 7-blade turbine, which is 31.85% at 8 m/s. Based on these results, it is concluded that the number of blades affects the performance characteristics of the Savonius type-S turbine. The 3-blade configuration produces the best torque and turbine power, while the 7-blade configuration excels in wind power and efficiency.

The manufacturing process is an activity of processing raw materials into products to increase added value. One of these products is chair furniture; to reduce errors and failures in its manufacture, it is necessary to do prototype model experiments first. This research conducts a simulation study and analysis of the chair design on stress, deformation and safety factor using the Finite Element Method approach with the help of ANSYS ADPL 18.0 static structural software where the chair design is made of 304 stainless steel, aluminum-T6, HCP 30 polymer foam in one chair structure by simulating several static load loading scenarios, boundary conditions, and even distribution on the surface of the chair. The simulation results show that the highest maximum stress distribution (von misses stress) is 3.5 Mpa at a pressure of 175 kg.f, for the lowest value of 1.5 Mpa at a pressure of 5 Kg.f and a deformation (displacement) of 0.145x10Ë‰4 mm occurs at a pressure of 175 Kg.f, while the lowest deformation value of 0.621x10Ë‰5 occurs at a pressure of 75 Kg.f, This is due to the loading increasing along with the applied pressure force, but still in the minimum safety factor standard position for static loads, so as not to damage the geometric structure.
