Abstract

Since each refrigerant has different vaporization and condensation temperature and pressure, the capacity and working conditions of each system depend on the type of refrigerant used. The criteria for a suitable refrigerant for a refrigeration system are determined by its thermodynamic, chemical, and other factors. This research aims to analyze the capacity and scope of work of refrigerator components that use R-22 refrigerant to be replaced with HCR-22 in a 1.7 TR refrigeration fish refrigerator without having to replace components. This research was carried out from December to March, on a regular fishing vessel, Alalunga Vessel. The research was conducted by reviewing and analyzing the application of refrigerant HCR-22 and R-22 in the refrigerator unit. The results of the analysis of the capacity and scope of work of the components show that HCR-22 refrigerant has a higher advantage than R-22. These high advantages have a positive reaction to the refrigeration effect and refrigerant workload, which include an increase in heat absorption capability, a decrease in compressor and electric motor energy, a decrease in the compression ratio, an increase in the compressor coefficient achievement.

Abstract

The catch of fish is so large and often not completely sold, causing the fish to be wasted for free. This situation even indirectly causes environmental pollution around the area where fishermen live. To overcome this problem, a fish drying machine was made using a PV system. This tool is also a form of solving the problem of the traditional fish drying process which is sometimes not clean, safe, and depends on direct sunlight. This PV system can meet 169.95% of the need for 240 Wh/day of electrical energy from fish dryers. PV system can produce electrical energy for 407.81 Wh/day, where the largest energy can reach 520 Wh and the smallest is 160.8 Wh. The results of the analysis of the impact of using fish dryers socially and economically also gave significant results (p<0.005), where there was an increase from before and after the use of fish dryers experienced by fishermen. When viewed from the perspective of fishermen on the tool, the accuracy of the use of the tool, the benefit factor, and the shape of the fish dryer, the fishermen gave a good response, with an average value of 4.19-5.26.

Abstract

The researcher analyzed the Real-Time Clock (RTC) alarm readings on the Arduino MKR Zero, Arduino MKR Wan 1300, and Arduino MKR GSM 1400. The Arduino MKR board compared the data with the accuracy of reading the RTC values. To support this research, experimental quantitative research methods were used, and an independent sample t-test was used. The use of this method is very suitable because this method displays numbers as data and also conducts experiments directly on the Arduino MKR board. Comparative measurement of the three MKR using the RTC Alarm get the average time difference. This average indicates the IC capability and accuracy of MKR. From the experimental results, MKR GSM 1400 has the greatest. Arduino MKR GSM 1400 is the Arduino MKR that has the fastest data response among the other two Arduino MKRs. So, to create or develop a project related to real-time data transmission, it is recommended to use the Arduino MKR GSM 1400.

Abstract

Utilization of new renewable energy can be one solution to the limitations of fossil energy. Ocean wave energy is renewable energy caused by tides, and this potential can be utilized as a source of electrical energy in Indonesia, especially East Nusa Tenggara. This ocean wave power plant uses oscillating water column (OWC) technology. This wave energy is energy that can be developed and environmentally friendly and available every time. This paper analyzes the amount of energy produced by ocean waves using OWC technology in the East Nusa Tenggara. The benefits of this paper can be used as a reference for planning the construction of a wave power plant around East Nusa Tenggara. The method used is to measure the condition of ocean waves for a year and analyze the amount of energy and electrical power that can be generated by ocean waves with the use of OWC. The results of the analysis show that the use of ocean wave power plants with OWC technology in the waters of East Nusa Tenggara can produce the highest energy of 20,291,728.83 Joules and the lowest is 17,062.62 Joules. The electrical power generated is between 3,645.45 Watt to 4,274,314.37 Watt, and average of power density by ocean waves using OWC is 19,021.89 Watt/m2.

Abstract

The abundance of fish catches in Indonesia is excellent potential. Still, if the abundant results cannot be adequately managed and are just wasted, it will eventually lead to bad things. This problem was also found in Seraya village, Karangasem, Bali, where large fish yields and the fish processing process were still constrained by weather and environmental conditions causing the expected results to not be achieved. To overcome this, a photovoltaic (PV) system-based fish dryer was developed that can assist the fish drying process. Utilization of this system is also supported by good solar energy potential. The system can generate 402.78 Wh of electrical energy per day, covering 104.89% of the electrical energy demand of the fish dryer. The results of statistical tests using the Mann-Whitney test for fish weight and unpaired t-test for fish moisture content showed no significant results (p0.05). This value states that there is no difference in the results of drying fish with the PV system and the traditional method. From this, we can conclude that fish drying using a solar power system works similarly to conventional fish drying methods.

Abstract

Keterbatasan BBM dan harga yang meningkat mempengaruhi perekonomian para nelayan di Indonesia. BBM ini memegang peranan penting dalam kehidupan para nelayan karena dipergunakan untuk menggerakan mesin induk dan juga generator di atas kapal. Untuk mengatasi permasalah terebut maka dicoba untuk mensosialisasikan PLTS dan Lacuda dalam mengurangi kebutuhan BBM di atas kapal. Sistem ini dapat mengganti penggunaan generator di atas kapal dan membantu proses penangkapan ikan para nelayan. Kegiatan pengabdian diberikan kepada para nelayan di Desa Oemata Nunu, dengan metode pemaparan materi, wawancara dan kuesioner. Kegiatan pengabdian kepada masyarakat untuk meningkatkan pemahaman keekonomian penggunaan PLTS dan Lacuda pada masyarakat Desa Oemata Nunu, Kupang Barat, Nusa Tenggara Timur berjalan dengan baik dan menunjukan adanya peningkatan pemahaman masyarakat. Hasil uji Wilcoxon, diperoleh nilai signifikan 0,001 (p < 0,05), dengan demikian disimpulkan bahwa terdapat perbedaan pemahaman yang bermakna antara sebelum dan setelah kegiatan. Pemahaman keekonomian penggunaan PLTS dan Lacuda ini diharapkan berguna untuk para nelayan. Selain bisa menjadi pendorong penggunaan PLTS dan Lacuda sebagai sumber energi listrik pada kapal nelayan juga secara tidak langsung mendukung kebijakan pemerintah dalam Blue Economy.
