Abstract

The South China Sea is one of the epicenters of conflict in the 21st century. The South China Sea area includes waters and land located in the archipelago of two large islands, namely the Spratlys and Paracels, as well as the banks of the Macclesfield and Scarborough Reef Rivers which stretch from Singapore, from the Malacca Strait to the Taiwan Strait. As this vast territory has often been subjected to successive control by neighboring rulers, several countries, such as the People's Republic of China (PRC), Taiwan, Vietnam, the Philippines, and Brunei Darussalam, have engaged in confrontational attempts to claim, over large parts of the entire territory. . While on the one hand Indonesia supports the prospect of peace in the South China Sea for economic development and domestic stability, Indonesian policymakers are concerned about China's interpretation of its South China Sea claims, which also includes reserves of natural gas and other natural resources. inside it. On the other hand, Indonesia is committed to defending the rights of the archipelagic state as stated in UNCLOS.

Abstract

Mas banana (Musa acuminata Colla) peel is a type of household waste as well as agricultural waste whose utilization still needs to be improved. In addition, among various types of heavy metals that are dangerous as contaminants in the environment, cadmium metal is a metal that is very dangerous to health even in very small amounts. Therefore, this study aims to not only utilize the waste of Mas banana peel (Musa acuminata Colla) as a biosorbent, but also to determine the optimum conditions needed to reduce cadmium metal which involves several test parameters, namely stirring time, pH and mass of biosorbent. Variations of stirring time used include 10, 20, 30, 35, and 45 minutes; variations in pH used include 1, 2, 3, 4, and 5, while variations in the mass of biosorbent used include 0.5; 1; 1.5; 2 and 2.5 grams. The results showed that the optimum conditions were obtained at a mixing time of 35 minutes, pH 5, and a mass of 2 grams of biosorbent with a reduction percentage value of 78.45%. This percentage indicates that Mas banana peel can be used as a natural adsorbent for cadmium metal. In addition, the results of the FT-IR analysis of the Mas banana peel biosorbent showed that Mas banana peel has a functional group that plays a role in the heavy metal adsorption process.

Abstract

 The Micro Gas Turbine is a device that functions to convert chemical energy from fuel from the combustion process into mechanical energy, which is then converted back to a generator to become electricity. This study aims to obtain the results of performance testing as well as the results of the comparison analysis of the Gas Turbine Micro from the design and testing of the assembly tool. The fuel used in this Gas Micro Turbine is LPG (Liquefied Petroleum Gas). The advantages of LPG are it is easy to obtain, has a high octane value so that the power generated is greater, has a high vapor pressure so there is no need to use a pump to drain it. The result of this research is that the addition of a fire source can increase the turbine inlet temperature although it is not significant because the fire does not burn continuously due to the compressor rotation being too forceful. In the first and second actual tool tests, the temperatures were 317.48K and 323.75 K, different from the results of the analysis on the ANSYS software where the temperature was 766 K and 793 K.

Abstract

The use of electrical equipment on the customer side with low voltage absorbs unbalanced power. The load unbalances in each phase will result in an unbalanced current, resulting in a phase voltage shift in the secondary coil of the 20 kV/380 V medium voltage transformer. Shifting the voltage in the distribution transformer phase, then causes the flow of current in the transformer neutral wire causing losses. This paper proposes a fuzzy logic method with the Mamdani fuzzy inference system (FIS) to balance three-phase load currents at seven feeders of 20 kV medium voltage distribution at PLN Rayon Taman Jawa-Timur. The feeders are Ngelom, Tawang Sari, Geluran, Bringin, Masangan Kulon, Palm Residence, and Pasar Sepanjang. There are three input variables used, namely the load current in phase R, phase S, and phase T respectively. There are three output variables in one FIS block, namely changes in load current in phase R, phase S, and phase T respectively. With the number of fuzzy rules as many as 509 rules, the proposed method is able to produce the lowest load current unbalance value of 1.6% at Palm Residence Feeders. The development of a nominal (number) of fuzzy rules in the Fuzzy Logic Method with FIS Mamdani is able to reduce the value of unbalance load current at the 20 kV medium voltage distribution feeder better than the method proposed by previous researchers.
