Abstract

Sumber Daya mineral Indonesia tersebar, salah satunya berada di Kabupaten Jombang. Kabupaten ini memiliki mineral Kaolinate. Kaolinite memiliki potensi untuk dijadikan bahan dasar pembuatan bata tahan api. Penelitian ini berhasil membuat bata tahan api dengan suhu pembakaran dengan rentang 900oC-1100oC yang kemudian dianalisis karakteristik termalnya. Karakteristik ini sangat penting karena bata tahan api difungsikan untuk mendistribusikan panas ketika proses peleburan atau pemanasan tungku. Analisis perhitungan Konduktivitas Termal terdapat pada sampel dengan kandungan fireclay sebesar 70% yakni sebesar 1.291(W.m/°C). Sedangkan pada fireclay sebesar 60% konduktivitas termal sebesar 1.271 (W.m/°C).

Abstract

Indonesia is a country with significant potential for developing solar energy. However, one of the challenges in the electricity sector is the reliance on fossil fuels as the primary energy source. To mitigate the impact of this dependence on fossil fuels, it is crucial to explore new sources of renewable electricity. Solar cells, which convert sunlight or ultraviolet (UV) rays into electrical current, offer a promising solution. Sunlight is a sustainable and abundant energy source, making it a viable option for future energy production. Due to the nature of solar cells, which depend on sunlight, the output they produce is variable and influenced by changing weather conditions. Therefore, energy storage solutions, such as lithium-ion batteries, are needed to store the electricity generated by solar cells. This study will examine the characteristics and efficiency of solar cell input on the capacity of lithium-ion battery storage systems, focusing on the relationship between sunlight intensity and the generated current and voltage. An off-grid photovoltaic (PV) system relies solely on solar energy, utilizing a series of photovoltaic modules. Consequently, sunlight intensity significantly impacts the solar cell's performance by affecting the voltage and current produced, which in turn influences the system's performance. This research aims to assess the efficiency, advantages, and disadvantages of comparing the output results between series and parallel configurations of solar cells to meet desired needs. Testing and data collection will be conducted using simulations with PV Syst and Meteonorm software.

Abstract

PT. Garuda Media Telematics is an internet service provider (ISP), this company really needs electrical energy to operate 24 hours a day. However, the electricity source distributed by PLN is not continuously available, sometimes sudden power outages will of course be a problem and loss for the company. Therefore, the use of Automatic Transfer Switch (ATS) and Automatic Generator Start (AGS) is the main technology in electrical automation systems to maintain power reliability. ATS operates on the front line when the power goes out, automatically switching from the main power source to a backup generator in a matter of seconds, ATS ensures that the electricity load will continue to be supplied without any interruption. Meanwhile, AGS will activate the electricity generator automatically when there is a power outage or disruption to the main power source. This system is important to ensure that the backup generator is activated when needed to meet the company's electricity needs.

Abstract

In our daily lives, we certainly cannot be separated from frozen processed foods that we usually find in supermarkets or other frozen food stores. There are many frozen processed foods that we can find on the market, one example is frozen chicken, frozen duck, frozen sausage and so on. PT. Phalosari Unggul Jaya is a company that focuses on the field of chicken, duck cutting and providing frozen processed or ingredients made from chicken. To meet the needs of frozen food in the community, PT. Phalosari Unggul Jaya now utilizes Air Blast Freezer technology or what is commonly called ABF, Air Blast Freezer is one of the food freezing tools in the world of refrigeration. In one ABF system, there are several supporting tools or components to support the running of this ABF system. One of the important tools or components for the running of the ABF ABF system is the condenser. The condenser is a tool in the refrigeration system of a cooling machine that functions as a heat transfer in the refrigerant that has a high temperature will be absorbed and then blown by the heat-inhibiting media in the condenser so that the refrigerant vapor condenses into liquid. The condenser is one of the important elements and its existence is very vital in a cooling system. The condenser acts as a heat evaporator from the refrigerant that has previously been compressed or compressed in the compressor for the refrigerant to be channeled back into the evaporator.

Abstract

An optimal attendance system is required to accurately record student attendance, which will ultimately affect their final grades. In the mentoring segment of the PAI-SPAI UPI Tutorial, a Google Apps Script-based attendance system implementing the Haversine formula is used. This research aims to analyse the attendance system to identify any issues that may cause data inaccuracies, rendering the system ineffective. The study employs qualitative and quantitative approaches, utilizing interviews, observations, literature reviews, and experiments. The results show that out of 5 Android devices and 5 iOS devices tested, 2 Android devices and 1 iOS device encountered issues preventing them from recording attendance. Additionally, the system's location accuracy and consistency were only 44.82%, which falls under the "moderately accurate" category, though it is close to the threshold of being "less accurate" (<40%). The research also identified a data overwriting issue, where existing attendance data was erased and replaced by newly submitted data within an extremely short timeframe. As a result, some participants who had already marked their attendance were not recorded. In conclusion, the attendance system used in the mentoring segment of the PAI-SPAI UPI Tutorial is still not optimal or effective, necessitating further development to improve its performance.
