Abstract

Abstrak Tugas akhir ini membahas tentang pengaruh temperatur permukaan sel surya terhadap kapasitas daya keluaran dengan suatu hipotesis yang mengatakan pada pukul 12.00 – 16.00 output dalam kondisi optimal tetapi ada penurunan kinerja sel surya sebagai akibat dari meningkatnya temperatur pada rentang waktu tersebut. Penelitian ini dilakukan di rooftop Gedung P (Deli) Fakultas Teknik Elektro Universitas Telkom dengan mengambil beberapa data menggunakan alat ukur temperatur permukaan sel surya dan arus yang dihasilkan sehingga mendapatkan data yang lebih akurat dan kontinu. Pengambilan data temperatur dilakukan pada tiga titik untuk memperoleh nilai temperatur permukaan panel surya. Selain itu, penelitian juga mengambil data intensitas cahaya. Pada penelitian ini, diperoleh nilai intensitas yang sama namun memiliki nilai arus dan temperature yang berbeda. Nilai daya keluaran pada panel surya dari pukul 12.00 hingga 16.00 menunjukkan penurunan dengan rata-rata penurunan sebesar 2,8991 W setiap 15 menit atau setara 0,1932 W/menit. Dengan kesimpulan bahwa temperatur memiliki pengaruh terhadap besar kapasitas daya yang dihasilkan oleh panel surya dengan pengaruh rata-rata sebesar 2,42 W/oC. Semakin tinggi temperatur panel surya maka kinerja panel surya akan menurun. Kata Kunci : Sel surya, temperature, energi terbarukan Abstract This final project discusses the change in the temperature of the solar cell with respect to capacity of the output power with the hypothesis that at 12.00 – 16.00 the output is in optimal conditions but there is a decrease in the solar cell as a result of the temperature in the specified time span. This research was conducted on the roof of P Building (Deli), Faculty of Electrical Engineering, Telkom University by taking some data using solar cell temperature measurement device and the resulting current so as to obtain more accurate and continuous data. Temperature data collection was carried out at three points to obtain the surface temperature value of the solar panel. In addition, the study also took light intensity data. In this study, we obtained the same intensity value but had different values for current and temperature. The value of the output power on the solar panel from 12.00 to 16.00 shows a decrease with an average decrease of 2,8991 W every 15 minutes or the equivalent of 0,1932 W/minute. In conclusion that temperature has an influence on the power capacity generated by solar panels with an average effect of 2,42 W/oC. The higher the temperature of the solar panels, the lower the performance of the solar panels. Key word : solar cell, temperature, renewable energy

Abstract

Lontong is a traditional Indonesian rice-based food that is wrapped and boiled until cooked. It has a relativel  short shelf life at room temperature, typically lasting only 1 to 2 days before spoilage occurs. In an effort to prolong its shelf life, some individuals have illicitly used borax as a food additive, despite its prohibition due to serious health risks. This study presents the design and development of a borax detection device for lontong using a turmeric-based colorimetric test integrated with a TCS3200 color sensor and an Arduino UNO microcontroller. Samples were prepared with varying borax concentrations ranging from 0 g/g to 7 g/g. Turmeric paper was used as a reagent, which changes color from yellow to orange or brick red in the presence of borax. The TCS3200 sensor detects the color change and converts it into frequency signals, which are processed by the microcontroller. The estimated borax concentration is displayed on an LCD module. The system demonstrated detection reliability rates of 100%, 100%, 96%, 96%, 90%, 100%, 98%, and 96% corresponding to each borax concentration level.Key Words: borax, lontong, mikrokontroler, turmerik, sensor TCS3200.

Abstract

Stunting is a chronic nutritional issue that hampers children's growth, characterized by height below the standard set by the World Health Organization (WHO). The primary cause is prolonged malnutrition, especially during the first 1,000 days of life—from pregnancy until the child turns two. In Indonesia, stunting has become a national priority due to its long-term impact on human resource quality and the country’s future. According to the 2022 Indonesian Nutrition Status Survey (SSGI), national stunting prevalence stands at 21.6%, while West Java reports 20.2%. In Bandung Regency, including Dayeuhkolot area, stunted children are still found, often due to inadequate monitoring during pregnancy and low maternal awareness about nutritional health. Efforts to reduce stunting should not focus only on toddlers but also prioritize early prevention during pregnancy. Maternal health—encompassing nutritional status, blood pressure, weight, and mid-upper arm circumference (MUAC)—plays a crucial role in determining the risk of delivering low birth weight (LBW) babies, a major stunting risk factor. However, many pregnant women lack knowledge of how to use basic health measurement tools like MUAC tapes, weight scales, and blood pressure monitors. Through this community service program, the team will conduct health education and practical training sessions for pregnant women at Posyandu 08 Melati, Citeureup Village, Dayeuhkolot. The initiative aims to improve maternal health literacy, equip participants with skills to use health tools, and raise early detection awareness for stunting prevention. A participatory, community-based approach will be applied to ensure sustainable impact in line with the government’s national stunting reduction agenda.
