Abstract

The use of fossil energy as a source of fuel to turn on generators on fishing boats has long been used to assist fishing activities in Tablolong Village. The availability and lack of good use of this energy continuously will certainly be very bad for the sustainability of the fishermen's economy and the environment. The utilization of solar energy which has such great potential in East Nusa Tenggara can be one solution. The use of this technology is in line with the Blue Economy policy by the Ministry of Marine Affairs and Fisheries Republic of Indonesia. This 80 Wp PV system is installed on a 3 GT ship, then the energy that can be generated is analyzed and the Wilcoxon test is carried out to determine the fishermen's response to the use of the PV System. The utilization of the PV System as a source of electrical energy on 3GT vessels in Tablolong Village can meet the electrical energy needs of fishing boats. The electrical energy generated can meet 189% of the ship's electricity needs of 320 Wh/day with energy that can be produced by PV of 604.04 Wh/day. This result is also supported by the Wilcoxon test of the energy produced by PV for the ship's electrical energy needs. Based on the assessment indicators that have been carried out from before and after PV installation activities on fishing boats, it was found that there was a significant difference in the electrical energy needs before and after using PV System with a significant value of 0.001 (p < 0.05).

Abstract

The generation and use of good electrical energy on a commercial ship will provide a sense of comfort and safety for everyone who uses the facility. The XYZ ship is one of the commercial ships in East Nusa Tenggara which operates to serve crossings from Kupang to Rote. This ship uses 3 generators to meet its electrical energy needs. This study aims to determine the consumption of energy and fuel used during shipping activities and to determine the condition of the generator used. The results of the analysis show that the percentage of generator loading on the ship's electrical load is still sufficient, with an average of 8.76%. The fuel consumption of the generator in one operation is 200.34 Liters/day, which is still appropriate and sufficient for the capacity of the fuel chamber on the ship. The use of generators is also carried out effectively and efficiently with alternating scheduling so that each generator can work optimally for a long time to avoid overheating.

Abstract

The limited stock and uncertainty of fuel prices as a source of driving the main engine and generator on ships greatly affect the lives of fishermen in Indonesia. Even though there is a policy in the form of assistance from the government in the form of subsidies, fishermen still feel doubtful about being able to get such assistance. To overcome this and with the potential of solar energy in Indonesia, as well as a manifestation of appropriate technology and blue economy policies, a photovoltaic system is made that is combined with underwater lights as a fishing tool. Activities are carried out by measuring environmental conditions and the energy that comes out of the PV system and giving questionnaires to the fishermen. The results showed that the use of PV systems combined with underwater lights in fishing activities gave good results. The result of electrical energy that can be generated is 393.24 Wh/day and can meet the ship’s electricity needs for 4 days. This result is also supported by the Wilcoxon test results for technical, economic, environmental, health, and safety aspects with a significance value of 0.001 (p<0.05).

Abstract

The limited fossil energy and uncertain prices have an indirect effect on fishing activities using a fixed lift net. Therefore, energy diversification is carried out by utilizing solar energy with photovoltaics on the fixed lift net. This energy is very abundant and available throughout the year, except during the rainy season. This study uses observation, interviews, and questionnaires given to fishermen and tries to compare the utilization of photovoltaic (PV) systems with generators using different types of lamps, such as LED, CFL, incandescent lamps, and halogen lamps. The use of PV systems in fixed lift nets from a technical and economic perspective allows it to be utilized in the long term. Based on the technical aspects, the PV system can produce 471.59 Wh per day. This technical result will be more profitable if the lamp used is a light emitting diode (LED) lamp. Meanwhile, from economic aspect, the use of electrical energy from a PV system is more profitable because it provides a lower operational value than a generator, and provides good net present value (NPV) and internal rate of return (IRR) values. This utilization is also supported by the good response from fishermen towards the energy produced and the ease of operation and maintenance of the PV system.

Abstract

Zada Hela Liveaboard is one of the tourist ships that serve shipping activities in East Nusa Tenggara, especially in the Labuan Bajo area. This ship is equipped with facilities that greatly pamper the passengers during their cruise activities. To be able to support and provide a sense of security and comfort to the passengers, good engine room watchkeeping activities are needed, but some shortcomings were found. The deficiencies in watchkeeping activities were then analyzed by observation and interviews with 6 respondents to make improvements. Improvement of engine room watchkeeping activities can finally be done by making a watchkeeping schedule, logbooks, and adding 3 assistant engineers. These items will be very helpful in checking and knowing the condition of the engine on the ship. The addition of 3 assistant engineers to assist the chief engineer is also very necessary. This is in accordance with STCW and to provide a longer rest time, so as to prevent fatigue when doing watchkeeping in the engine room.

Abstract

The fuel system is one of the main engine support systems which is very important in the operation of the Express Bahari 1F main engine. Operation of the main engine requires special treatment of the components of the main engine to prevent failure during operation. The Failure Mode and Effect Analysis (FMEA) method is a method that can be used to identify the priority scale in maintaining a machine by evaluating the risk of failure occurring on the machine. This research uses FMEA analysis to determine the priority scale for maintenance of the Express Bahari 1F main engine fuel system. The identification results show that the injector, fuel filter and separator components are components that must be prioritized for maintenance. This type of maintenance is carried out by checking for dirty fuel which can cause the injector to operate less than optimally, cleaning deposits on the fuel filter cartridge on the fuel filter, and replacing a new separator if the separator performs poorly. It is recommended that other components be checked so that the main engine fuel system has good reliability.

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.
