Abstract

Banjarwaru village is one of the villages in Cilacap district with the potential for wooden broom handle craft commodities. The processing of mahogany wood (Swietenia mahagoni) into broom handles produces wood waste that has not been utilized optimally. The accumulation of wood waste is caused by a lack of knowledge among the Banjarwaru village woodworking community regarding the potential dangers, benefits, and economic value of wood waste. Therefore, training in wood waste processing into value-added products such as particleboard is needed. The Community service team together with BUMDes Banjarwaru carried out mentoring activities as a solution method for utilizing wood waste. The mentoring activities carried out consist of educating the negative effects of wood waste on the environment, educating the potential and benefits of wood waste in another processed forms, and training in wood waste processing into particleboard. These series of activities succeeded in increasing the woodworking community understanding of wood waste by 81.6%. The success rate of mentoring reached 91,67% shown by 11 out of 12 mentoring participants understood the potential danger, benefits, and other processed forms of wood waste.

Abstract

Budidaya kepiting bakau (Scylla spp.) merupakan salah satu kegiatan ekonomi yang memiliki potensi tinggi di wilayah pesisir. Namun, keterbatasan lahan budidaya dan penggunaan sistem konvensional menjadi kendala dalam peningkatan kapasitas produksi. Kegiatan pengabdian kepada masyarakat ini bertujuan menerapkan sistem budidaya kepiting model tray berbasis energi terbarukan di Eduwisata Cigimbal Park, Kabupaten Cilacap. Sistem yang dikembangkan mengintegrasikan kompartemen tray bertingkat, Recirculating Aquaculture System (RAS), dan Pembangkit Listrik Tenaga Surya (PLTS). Metode pelaksanaan meliputi survei lokasi, perancangan dan instalasi sistem tray, pemasangan sistem filtrasi dan RAS, instalasi PLTS, serta pelatihan pengoperasian dan perawatan sistem kepada mitra. Hasil kegiatan menunjukkan bahwa sistem budidaya kepiting model tray berhasil diimplementasikan dengan baik dan mampu meningkatkan kapasitas budidaya dari 4 ekor/m² pada sistem floating crab box menjadi 12 ekor/m² pada area yang sama atau meningkat sebesar 200%. Integrasi RAS membantu menjaga kualitas air melalui sirkulasi dan filtrasi berkelanjutan, sedangkan PLTS menyediakan sumber energi yang ramah lingkungan untuk mendukung operasional sistem. Program ini menunjukkan bahwa penerapan sistem tray berbasis energi terbarukan berpotensi meningkatkan produktivitas budidaya, efisiensi pemanfaatan lahan, dan mendukung pengembangan ekonomi masyarakat pesisir secara berkelanjutan.

Abstract

Optimization of volute design is essential for the performance of centrifugal pumps and blowers. This study investigates the effect of volute tongue angle variation on air velocity and flow rate in volute casing design using flow simulations. The volute design was tested with tongue angles of 15°, 30°, 45°, 60°, and 75°, based on theoretical equations of flow rate and volute radius. Simulation results indicated that increasing the volute tongue angle enlarges the volute cross-sectional area. Generally, this enlargement decreases air velocity but increases the flow rate. A 75° tongue angle produced the highest flow rate of 4.860 m³/s, while the highest velocity, 21.35 m/s, was observed at 15°. This behavior aligns with the principle of mass conservation, where a larger cross-sectional area leads to reduced fluid velocity. These findings suggest that volute designs with larger tongue angles can optimize the flow capacity.

Abstract

In this research, the design process of the third generation of electric motorcycles (SEMOLI) is carried out, which is a development of the previous generation with the aim of developing electric vehicles using gearboxes, in order to add acceleration ratios to adjust to road or terrain conditions. as an alternative solution to the increase in fuel and the depletion of fossil energy sources. The results of this study support the national electric vehicle conversion program. The results can be used for the development of the automotive industry. The method used is research and development (R&D). The design process begins by calculating the design requirements for power transfer and frames. The frame simulation process produces a maximum stress of 149 MPa with a allowable stress of 163.2 MPa with a displacement of 2 mm. It is said to be safe to continue the manufacturing and fabrication process. The vehicle trial process produces a maximum vehicle speed of 55 km/h with an average energy consumption of 27 watts/hour.

Abstract

Background. BUMDes Banjarwaru Sejahtera is a business owned and managed by the people of Banjarwaru Village, Cilacap Regency. Some of the businesses that have been managed by BUMDes Banjarwaru Sejahtera include renting molen machines and making handicrafts such as broom handles and woven bamboo household crafts which produce an abundance of wood waste left over from the production process. So far, this wood waste has been sold to tofu craftsmen as fuel for the tofu production process. Purpose. People can use wood waste as added value by processing wood waste into handicrafts that have high economic value so that they can improve the welfare of the people of Banjarwaru village.

Abstract

The ever-increasing demand for electrical energy drives the utilization of renewable energy as a sustainable alternative source. Wind energy is one such potential renewable energy source. As a region situated on the southern coast of Java, Cilacap Regency possesses relatively stable wind characteristics, making it a promising location for the development of wind power plants. This study aims to analyze the wind energy potential in the Cilacap region using the Weibull distribution. The Weibull method was employed to determine the shape parameter (k) and scale parameter (c) based on wind speed data. The analysis results indicate an average wind speed of 6.225 m/s in the Cilacap region especially Teluk Penyu Beach, with Weibull parameters of k = 2.972 and c = 6.973 m/s. These values ​​reflect wind characteristics that are relatively stable and favorable for the development of small- to medium-scale wind power plants. The calculated wind power density (WPD) indicates that the coastal area of ​​Cilacap is suitable for harnessing wind energy as an alternative energy source.

Abstract

Semi-automatic water purification machines are urgently needed by the people around the Sitopong river, Cilacap Regency. Required application and testing of the YF-S201 type water flow sensor based on Arduino Uno. This is done so that the application of the water speed sensor in the river water purification machine can be maximized. The research method used is a literature study related to Arduino Uno and conducting experiments. The experiments were carried out in the form of testing the water flow velocity sensor, carrying out the process of calibrating the water flow sensor. Sensor testing was carried out 10 times after calibration. Based on the calibration results, an average volume of 329 ml was obtained from the desired volume of 330 ml so that an error of 0.3% was obtained. Whereas at the desired volume of 600 ml, the average volume of the calibration results is 598 ml, it can be seen that an error of 0.3% is obtained at a volume of 600 ml. Function test on the water filling process with 10 trials obtained an accuracy of 99.6% for a 330 ml volume bottle and 99.6 ml for a 600 ml volume bottle.
