Abstract

Ponggang Village is located in Serangpanjang District, Subang Regency, West Java. There is a natural beauty in Ponggang Village that is not yet known by many people, namely Curug Ponggang with its natural beauty and soothing atmosphere. To get to Curug Ponggang, there is only one main road access. However, the problem is that there are no lighting facilities on the road access with a road length of 700 meters and a road width of 1.2 meters so that with slippery and steep road access conditions, high vigilance is needed when crossing this road, especially at night or at night. foggy. Therefore, this study aims to examine the planning for the construction of Solar Street Lighting (PJUTS) on the Ponggang Curug access road to improve the comfort and safety of road users. There are 4 alternative concepts, where one selected alternative provides a total PJUTS budget plan for 15 years. The chosen alternative concept uses a PJU lamp post with one arm using a 50W LED Solar Light Model GW8833 lamp. Based on the research that has been done, it takes as many as 22 light points with each lamp post 33 meters apart and the pole height is 3 meters. It is hoped that the construction of these lamps can improve the quality of effective and efficient lighting in Curug Ponggang

Abstract

Fie Fie Joe animal shelter employees and visitors often physically contact animals while feeding, playing with, or cleaning animals and their cages. In order to prevent virus and bacteria transmission, animal shelters require everyone to wash their hands after visiting the outdoor area. The Fie Fie Jo shelter, however, faced two main problems. First, only one hand-washing station is available in their facility, allowing possible viruses or bacteria to be transmitted through physical contact with other people or objects before entering the indoor facility. Second, their staff took a long time to bathe the animals in their enclosures since there was no washing station in the outdoor area. Therefore, this outreach program aims to design and build a multi-purpose washing station for the outdoor area that can be operated by a foot pedal so that users do not need to touch the faucet physically. The washing station has additional features such as a large tub that can also be used for bathing animals, a tissue holder, and a garbage disposal to help make it easier and faster to bathe several animals simultaneously. The method used during the outreach program includes conducting a survey, performing a design process, and demonstrating how to use and maintain the multi-purpose washing station. To assess the success of this program, the Fie Fie Jo owner and employees were asked to fill out a questionnaire. The results showed that they were more than satisfied with the demonstration and performance of the washing station. The presence of the multi-purpose washing station can improve productivity and reduce the risk of viruses and bacterial contamination of the Fie Fie Joe animal shelter employees and visitors.

Abstract

UMKM Mulya PS Shop is a business that sells pet food. The problem faced by the Mulya PS Shop owner is that the shop still uses a sales and service system using manual methods, such as using notes. This problem results in an inaccurate number of orders and income results. As well as problems for consumers, where consumers have to come and order directly at the shop. This makes it difficult for consumers or customers who want to order remotely or outside the area. So based on the problems above, it is necessary to design an information system for making an Android-based goods ordering application and provide socialization of the Android-based goods ordering application to help Mulya PS Shop business owners have complete information and an easy and fast transaction system. By socializing the Android-based application information system, it can help accelerate technology transfer to Mulya PS stores. The application that has been created has fulfilled the purpose of service, namely helping MSME owners and customers, in the goods ordering system and transactions. And the socialization activities have been successfully carried out with good results and are very good at conveying the material and objectives. It is hoped that with this service activity, there will be integration between the Community Service Program and the final assignment courses.

Abstract

Air Conditioner pada umumnya digunakan sebagai pengkondisian udara di dalam ruangan agar mendapatkan kenyamanan termal. Pada sistem Air Conditioner (AC) ada kalor yang dibuang ke lingkungan pada saat refrigerant berada di kondensor tanpa dimanfaatkan. Mempertimbangkan bahwa energi panas yang terbuang di kondenser ini cukup besar, kaji eksperimental dilakukan untuk mengukur efek penggunaan kalor terbuang ini untuk memanaskan air dengan cara menambahkan Heat Exchanger (HE) pada bagian kondensor AC tipe split berukuran ¾ pk dalam meningkatkan kinerja Air Conditioner. Pengujian sistem AC dilakukan selama 60 menit untuk mendinginkan ruangan berukuran 3 m x 5 m hingga temerature di dalamnya mencapai 25,2oC. Dari hasil pengukuran didapatkan rata-rata Coefficient of Performance (COP) untuk AC yang dilengkapi dengan Heat Exchanger adalah 5,99, sedangkan untuk AC standar diperoleh nilai COP rata-rata sebesar 4,98. Hal ini berarti penambahan Heat Exchanger pada AC split dapat menghasilkan peningkatan COP sebesar 20,32%. AC dengan Heat Exchanger juga dapat memghasilkan air hangat dengan temperatur 45,9° C dalam waktu 60 menit.

Abstract

Pressure Reducing Valve (PRV) is a control valve designed to reduce upstream pressure to downstream pressure on fluid flow. When operating, a PRV is in an equilibrium condition because of the forces acting on it, such as fluid resultant force, membrane force, and spring force. On some working conditions, a PRV cannot operate because the equilibrium is unattainable by the spring that deflects further than the maximum allowable limit and unable to produce force balancing out other forces. Therefore, a modification on the spring wire diameter from 17 mm to 20 mm is conducted without altering other PRV parts dimension and geometry. The modified spring will be analysed through analytical analysis and simulation analysis with Ansys software. On the same working conditions with the enlargement of the spring wire diameter, the deflection that once was 99,28 mm decreases to 42,64 mm and does not exceed the maximum limit at 74,375 mm so the PRV can operate on said condition and the pressure drop range increases from 7 bar to 9 bar.

Abstract

Tarakanita Gading Serpong Senior High School aims to be an educational institution as well as a research center that adheres to the concept of education for sustainable development. Therefore, the staff of Tarakanita Gading Serpong High School wanted a teaching module that could serve as a learning tool for students, as well as a research instrument for the staff to study the use of renewable energy sources in the form of solar power. To meet their needs, a prototype of a small solar module that can simulate how a solar panel works and measure its output voltage, current, and electrical power was designed and built. The module is equipped with a 50 Wp polycrystalline solar panel, a solar charge controller to regulate the distribution of electric current, an 18 Ah battery to store energy, and an electrical load in the form of an 18-Watt light bulb.  The solar module is designed to be easily moved and operated indoors or outdoors. When the module is indoors, a 75 W Halogen UV lamp is used as a proxy for sunlight. Hopefully, this solar module can serve as an effective learning medium to introduce the use of solar power as a renewable energy source for Tarakanita Gading Serpong High School students.

Abstract

Ponggang Village, located in Subang Regency, West Java, possesses a tourist attraction in the form of Ponggang Waterfall. However, the management of Ponggang Waterfall as a tourist attraction still needs more attention. One of the challenges is that access to Curug Ponggang goes through a fairly steep trail, which still needs to be equipped with a railing to separate the road from the ravine, so the level of safety still needs to be improved. Therefore, the purpose of the service activities carried out by the Community Service Program team from the Faculty of Engineering at the Atma Jaya Catholic University of Indonesia is to design and build suitable railings on the access trail from Ponggang village to Curuk Ponggang to improve safety, comfort and smooth activities for village residents and visitors. The stair railing will be made from PVC pipe, steel wire, and jute rope. The existence of the railing will increase the potential of Ponggang Waterfall as a tourist attraction, especially for domestic tourists.

Abstract

According to the SNI 01-2721-1992 standard, the permissible moisture content for fish is around 40%. However, fresh fish naturally contains more than 40% water. To meet this standard, fish must undergo a drying process. In Indonesia, salted fish is commonly prepared by sun-drying the fish on bamboo mats. However, this method has several drawbacks, such as requiring large areas of land, heavy dependence on weather conditions, long drying times, and the risk of contamination by dust and dirt. One solution that has been developed is an artificial drying method using a greenhouse effect. In this activity, a drying tool shaped like a rectangular prism was designed and equipped with stones at the bottom to store heat and exhaust at the top. This tool was tested by comparing the mass of the fish before and after drying. The results showed that the fish's initial mass of 24.22 grams decreased to 21.28 grams after being dried for 2 days at an average temperature of 36.7°C.
