Abstract

Solar energy is one of the sustainable and environmentally friendly energy sources. However, this renewable energy is still not widely utilized by the people of Indonesia even though Indonesia, as a tropical country, has vast solar energy potential. Hence, It is essential to introduce and socialize solar energy potential to the general public. The partner of this community outreach program is Mekar Lestari Orphanage in South Tangerang. The orphanage care for children aged 3-16 years from various backgrounds. As a younger generation, it is hopeful that they can develop a mindset of solar energy as one of the renewable energy sources that can replace fossil fuels. In addition, the Mekar Lestari Orphanage in its social role requires a facility with adequate lighting. However, there was a lack of lighting in the front yard of the orphanage, making access to the facility difficult, especially at night. Therefore, a solar energy-based lighting system has been built and installed on the front gate of the orphanage. After installing the lighting system, socialization about the basic theory of solar energy and how the solar-powered lighting system works was conducted. The evaluation of the event, attended by representatives of staff and children living in the orphanage, showed that all participants gained new knowledge and a deeper understanding of solar energy. In addition, they learned new skills to operate and maintain solar lighting systems. From the positive feedback during the socialization, it is hopeful that this activity can provide education on the actual application of solar energy and help to improve lighting conditions in the orphanage.

Abstract

Aquarium cleaning is routine maintenance that must be done to maintain dissolved oxygen levels in the water to ensure the survival of aquatic biota. Maintaining cleanliness and water quality is key to preventing the water in the aquarium from becoming cloudy and emitting a foul odor due to increased ammonia levels in the water. However, aquarium cleaning is quite time-consuming and laborious, which becomes a problem for Jakarta Aquatics, which is engaged in selling and purchasing ornamental fish. As a solution, a prototype cleaning equipment that can simplify the process of maintaining the cleanliness of the water in the aquarium was designed and built. In general, the cleaning equipment designed consists of an acrylic screen that acts as a pseudo-base that collects fish waste at the bottom of the aquarium tank. Pumps are then used to remove water and waste from the aquarium easily, so there is no need to remove aquarium inhabitants during the cleaning process, thereby minimizing the possibility of fish death due to stress. The method used during the outreach program includes conducting a survey, performing a design process, and demonstrating on how to use and maintain the cleaning equipment. To assess the success of this program, Jakarta Aquatics owners and employees were asked to fill out a questionnaire. The questionnaire results showed that partners were more than satisfied with the equipment performance and the demonstration event. It is hoped that using this cleaning equipment in their aquariums can help improve the productivity of Jakarta Aquatics employees.

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

Indonesia is one of the countries affected by the COVID-19 pandemic. One of the most effective ways to prevent the spread of the COVID-19 virus is by regularly washing hands with soap for 20 seconds. With the pandemic conditions improving and the government lifting COVID restrictions, learning institutions can continue learning activities with the requirement that they obey strict health protocols. One of the private tutoring institutions in Tangerang that has resumed operations is Hikari Private Tutoring. With many people using the same facilities for educational activities, Hikari Private Tutoring is required to provide facilities for washing hands. Based on the inputs from Hikari Private Tutoring management, a touchless hand-washing facility was designed to minimize COVID-19 transmission. The hand washing facility also has an LCD to play videos of correct hand washing procedures and show how long the user has washed their hands. At the end of this activity, the manager and staff of Hikari Private Tutoring were asked to fill out a questionnaire. The results showed that they were satisfied with the functionality of the touchless hand-washing facilities. This hand-washing facility can hopefully help educate the public, particularly the staff and students of Private Tutoring, on the correct technique to wash their hands and prevent the spread of COVID-19.

Abstract

Penggunaan Printer 3D saat ini sudah semakin luas dan banyak macam bentuk yang dapat dibuat karena sistem layer-by-layer. Pada penelitian ini dilakukan pengukuran laju aliran volumetrik (debit) menggunakan material Thermoplastic Polyurethane (TPU) sebagai filamen printer 3D. TPU memiliki karakteristik material yang elastis. Pada eksperimen, dapat dibuktikan bahwa fluida TPU memiliki sifat non-newtonian, yaitu shear-thinning karena semakin besar temperatur dan kecepatan input yang diberikan pada fluida menyebabkan peningkatan debit outlet. Pengukuran laju aliran volumetrik (debit) fluida ditujukan agar dapat diketahui pengaruh viskositas fluida terhadap kestabilan debit aliran. Data hasil eksperimen dibandingkan dengan data hasil simulasi menggunakan perangkat lunak ANSYS Fluent 17.2. Data hasil simulasi belum dapat menunjukkan pengaruh viskositas terhadap debit aliran diakibatkan data yang dimasukkan pada perangkat lunak hanya berdasarkan dari jurnal dan lembaran data spesifikasi produk pabrik tertentu.

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.

Abstract

The traditional process of peeling a pineapple using a knife is complex and time-consuming. Therefore, a specialized peeler is needed to increase the productivity of honey pineapple peddlers located in the Cisauk area, South Tangerang. The objective of this service activity is to design a prototype of a pineapple peeler using press technology that can peel pineapples more quickly and efficiently, and produce more precise and uniform cuts. This pineapple peeler consists of a knife ring with a diameter of 11-12 cm. It is also equipped with a spring system with an inner diameter of 30 mm, an outer diameter of 41 mm, and a length of 206 mm which functions as part of the mechanism to automatically return the knife ring and pressing lever to their original position. The knife and spring components are made from food-grade Stainless Steel 316 and 304, rsepectively. The test results show that the prototype peeler can peel honey pineapple measuring 10-12 cm in diameter in an average time of 13.11 seconds. It is hoped that the use of this peeler can help increase the productivity of small pineapple peddlers, as well as reduce their burden and work risks.
