Abstract

Kapal Motor (KM) Sena Express merupakan salah satu kapal yang melayani penyebarangan di Nusa Tenggara Timur. Kapal ini tentu saja harus didukung dengan mesin yang baik untuk dapat memberikan rasa aman dan nyaman kepada seluruh penumpang dan awak kapal. Kurang optimalnya atas sistem kelistrikan dan konsumsi bahan bakar generator pada kapal, maka diperlukan suatu kajian lebih lanjut. Tujuan penelitian ini untuk menganalisis optimalisasi pembebanan dan konsumsi bahan bakar pada KM Sena Ekspress. Metode dekriptif analitik dengan observasi, wawancara, perhitungan beban listrik, dan konsumsi bahan bakar digunakan dalam mendukung kegiatan ini. Berdasarkan hasil analisis didapatkan bahwa total beban dan energi listrik sebesar 1655 W dan 25,8 kWh, dengan persentase pembebanan 55,17%. Meskipun kapasitas generator masih dapat menyuplai kebutuhan beban listrik di atas kapal, namun persentase pembebanan ini perlu ditingkatkan kembali hingga mencapai 60% sampai 86%. Hal ini dilakukan untuk keamanan, masa penggunaan, dan keekonomian dari generator. Sedangkan, untuk konsumsi bahan bakar generator selama beroperasi dibutuhkan solar sebanyak 7,2 sampai 10,8 liter. Untuk mengoptimalkan konsumsi bahan bakar ini, maka dapat dilakukan dengan membawa cadangan solar sebanyak lebih dari 1,3 liter.

Abstract

Bali is one of the islands with the largest Hindu religion in Indonesia. This is of course an attraction for tourists to see the culture and natural beauty that the island of Bali has to offer. However, apart from that, there are many religious activities that occur on the island of Bali and the waste produced is something that needs special attention. If this waste is not handled properly, it will threaten environmental sustainability in Bali and indirectly the tourism offered. Therefore, there is a need for a solution to overcome the waste problem. By conducting observations, interviews and literature studies, a way to overcome this problem was found, namely by converting the waste into aromatherapy incense, vermicomposting, briquettes and biofuel. The results of this processing have been studied and of course have the potential to be carried out on the island of Bali. The application of this method also indirectly plays an important role in preserving the environment and economy on the island of Bali.

Abstract

The utilization of fishing gear has been growing until now. One of these tools is an underwater fishing light that has been used by fishermen. However, until now this device still works conventionally and only provides one color. Based on these problems and the rapid development of the internet of things (IoT), an underwater fishing light was created and designed that can work with the IoT system and provide various colors of light according to the needs of fishermen. The design of this tool uses several tools and materials, such as generators, power adapters, controller modules, generators, and the Magic Home Pro application. This tool operates at 12 V DC and consumes 144 W of electric power. Utilization of this tool can also indirectly reduce the consumption of electrical and fuel energy on board and support the blue economy. The results of testing the device show that the IoT system can work well, provide light colors according to orders, is waterproof, and provides a fairly good light intensity with an average of 6.89 Lux (0-8 Lux).

Abstract

The utilization of sawdust waste in East Nusa Tenggara has not been utilized optimally. This waste is only burned, so it sometimes causes air pollution. So there needs to be an effort to overcome these problems by making alternative energy in the form of briquettes. Analytical description method with observation, literature study and economic and energy analysis is used in this research. Sources of data in this observation came from direct observations in the field through questionnaires and interviews. Based on the data of sawdust waste produced can reach 20-60 kg per day and can be used as other forms of energy. This energy can be used as a source of electrical energy to replace conventional energy which is less environmentally friendly and fuel for burning fishery products in East Nusa Tenggara. Based on the value of the benefit-cost ratio (BCR) and payback period, good results were obtained with a value of 2.13 with a return on investment of 0.82 years. The generated electricity biomass can replace conventional electrical energy and provide cost savings of 19.2% per kWh. In addition, the utilization of this energy can have a positive impact on regional income, health, schools, and transportation as well as agriculture.
