Abstract

The energy crisis has required the government to develop and utilize a renewable energy. Indonesia has a national jurisdiction area of ± 7.8 million km² with 2/3 of its territory being the sea of ± 5.9 million km². With this large sea area, it is a great potential for Indonesia to be able to develop alternative energy resources in the maritime sector amid the problem of fossil energy resources whose capacity is decreasing. Alternative energy in the maritime sector that can be developed include energy that utilizes ocean waves, ocean currents, tides, and ocean temperature differences. This study aims to determine the alternative energy of the maritime sector by reviewing from technical and financial aspects, political, economic, social and technological aspects. The method used is technical analysis, financial analysis, PEST analysis, and Fuzzy MCDM. The first step in this process is the mapping of the technical, financial, political, economic, social and technological aspects of each energy alternative with technical, financial and PEST analysis. Furthermore, with the Fuzzy MCDM method an alternative energy development selection model was made by assessing the performance of each. Based on the results of data processing shows the ranking of determining the alternative energy of the maritime sector with the first is the source of ocean current energy, the second is tidal energy, the third is wave energy and the last is Ocean Thermal Energy Conversion (OTEC). Keywords: Alternative Energy Resources, PEST, Fuzzy MCDM

Abstract

ABSTRACTEfforts to increase the degree of public health as high as possible are carried out by creating a clean life, eliminating breeding grounds for disease causes and agents, keeping food and beverages clean and not contaminated by disease-causing and intermediate bacteria, and implementing healthy habits. Rats are nuisance animals that harm humans because they eat all types of food eaten by humans. The Rat can become agents of several pathogens that cause disease in humans because the relationship between rats and humans is often parasitic, one of which is PES. The disease can be transmitted directly by saliva urine, and feces, or through ectoparasite bites in rats (fleas, fleas, and mites). This type of research aims to see the efficiency level of single trap type mouse trap with double trap type in Kade Jamrud and Kade Perak, Tanjung Perak Port, Surabaya. This type of research is pre-experimental with a one-shot case study design, that is, in this design, the treatment or intervention has been carried out (X), then the measurement (observation) or post-test (O) is then analyzed in statistical calculations using the t-test calculation. with a significant level of 5%, to find out which type of trap is the most effective compared to other types of traps. The results of this study indicate that out of 200 traps placed in 5 different warehouses, each warehouse has 40 traps with the same composition ratio. During the study, the number of a rat trapped was 14. The double trap mouse trap received the highest number of rats, namely 10 or 71.4%, while the single trap mousetrap only received 4 or 28.6%. From the results of the study, a statistical test was carried out where the t count the source of treatment variation was 1.630 while t table was 1.860, so it can be concluded that between single trap and double trap mouse traps showed no significant difference in the number of a rat trapped.Keywords: Single Trap, Double Trap, t-test.

Abstract

The South China Sea conflict is a regional security issue that has not yet reached the point of completion, and is prone to disrupting regional stability in the future. This dispute was initiated by China's unilateral claim to expand its territorial waters based on the nine dashed-line theory. This triggered diplomatic protests by several countries that directly border the South China Sea, including Indonesia. Even more recently, this has attracted the attention of the United States to participate in wanting to control and have influence over the South China Sea area which is considered very strategic and brings enormous economic benefits to its country. To avoid conflict, a strategy and policy scenario from each country in this case is needed, namely Indonesia, China and the United States using Game Theory. The Game Theory method that is simulated in this study uses pessimistic and optimistic scenarios from each country. Furthermore, the output of this method is that a saddle point is obtained from the scenario carried out by the three players/countries so as to achieve Ranai Region Stability in the South China Sea Conflict. Keywords: Strategy, Policy, Regional Stability, and the South China Sea

Abstract

Piracy and piracy incidents that often occur in Indonesian waters greatly affect the credibility and dignity of the Indonesian nation in the eyes of the international world. Based on existing data, piracy and piracy in Indonesian waters became the most in the world, especially in the waters of the Strait of Malacca. This condition certainly has a negative impact on the Indonesian government. Even the International Maritime Bureau (IMB) gave the title "Black Area' in the waters of the Strait of Malacca. This statement is based on the number of reports of piracy and piracy incidents in Indonesian waters. There are several studies that take the theme of location selection by Analytic Hierarchy Process (AHP) and Geographic Information System (GIS) methods. Wang (2009) stated, although the AHP method is more widely used in building a decision-making system, but this method has drawbacks, namely not considering the uncertainty and doubts in decision making. Therefore Fenton &Wang (2006) argues fuzzy-set theory can be used to overcome the limitations of AHP. This study assessed that site selection with Fuzzy AHP and TOPSIS can reduce decision uncertainty. GIS is used to analyze and describe the real relationship between the points of piracy incidents that have occurred with the position of the surrounding Navy Base. This research can help determine the best Navy bases from several existing bases, especially those around the waters of the Strait of Malacca. This base will then be used as an base for KRI and personnel who are carrying out maritime security operations in order to handle piracy and piracy crimes. In the research area limited by sea map no. 2 production of Dishidros TNI AL, there are 7 Naval Bases that can be used as alternatives namely Lanal Batam, Lanal Tanjung Balai Karimun, Lanal Dabo Singkep, Lanal Dumai, Lanal Tanjung Balai Asahan, Lanal Lhokseumawe and Lanal Sabang. From the results of weighting and warkingan, Naval Base Batam was selected as the best aju base from a scale of 0-1, with a weight value of 0.8442. Keywords: Piracy, GIS, Fuzzy AHP
