Abstract

Batteries or accumulators on the car serves to store electrical energy in the form of chemical energy, which will be used to supply the system to the electric starter, ignition system, lights and other electrical components. In the car, the battery damage can occur due to many factors including temperature. Batteries that work at higher temperatures will have a life span that is lower than at normal room temperature (25OC). Generally, the location of the battery is in the engine room so that the battery position was close to the engine. The car engine works at the optimum temperature 80 ° C - 90 ° C so that the heat is around the engine room can be exposed directly to the battery and can affect the performance and lifetime of the battery. Adding insulation on cover, with low thermal conductivity coefficient will decrease heat transfer rate . Polyurethane as insulation with 7,5 mm thickness will maintenance battery liquid temperature 45,5 OC after running through three hundred minutes.

Abstract

The fishermen in Kasemen subdistrict are the traditional fishermen who depend on the stars in the sky for navigation in caching fishes at the ocean . So, they do not go to the ocean everyday. There are many days that they must stay at home. They have another skill besides the fishermen. That is a problem. A solution of this problem is producing a special boat for the ocean tourisme. The boat is katir boat that made from plastics and combine with the glass at the bottom to see the beautiful under water views. The fishermen could be the guide of the sea tourisme because this area is rich with life and under water views. For the first , study to calculate of the cost is to be done , make a design of katir boat with the glass on the bottom and steps of production with economy of engineering method. The results are if the fishermen have to make the boat (Katir) with a special type by themselves need a lot of cost Rp.11.500.000 by a boat (without the engine) . If  the owner of the boats want to make of Katir production from fiberglass with a glass on the bottom as a special type for the ocean tourisme make a lot of cost Rp.12.710.000 by a boat (without the engine)  and get a Rp.1.110.000 profit  after reduced by production cost Rp.11.600.000 by a boat. If the investors want to enter the bussiness of  Katir industry seriously , the capital will be back (Break Event Point/BEP) on time of 4.5 years or after 10th Katir production.

Abstract

PT. X is one of the companies engaged in the field of an aircraft-maintenance and repairing services. PT. X classifies the aircraft spare parts into three groups namely rotable, repairable, and expandable. PT. X has a problem of having shortage inventory of the expandable spare part with 9 unit total of shortage in 2016. If this problem occurs continuously, it can increase the total inventory cost. Therefore, this study discusses the improvement of the inventory control of the expandable spare parts.The first phase of this study is forecasting the existing spare parts of the A Classes. Then, we determine the maximum inventory and the average inventory in warehouse using min-max method. After that, we determine the inventory level which covers ordering period (T), maximum inventory (R) and the average inventory in warehouse using Periodic Review Models. The final phase of this study is comparing the total inventory cost between Periodic Review Models and Min-Max method.The Classification with ABC method result 5 spare parts from A Class with a percentage of total items are 12.5% from 40 total item. Meanwhile, the total value of A Class amounted to 71.80% that had Rp 132,285,644.22 from the total price Rp 184,218,274.36. Periodic Review Models result an ordering period (T) and maximum inventory (R) which is optimal and can minimizes shortage 0 unit from 6 unit in A Class. With this decreased of shortage, it can minimizes the total inventory cost from the company. The comparative results between the total inventory cost using Periodic Review Models and Min-Max Method is Periodic Review Models has a smaller total inventory cost than Min-max Method with a total saving of inventory cost amounted Rp 81,121,836.62 and the percentage savings of 39.25%.

Abstract

Hydroelectric Power Plants (PLTA) in Indonesia have been around since 1926, and are still operating today. The Indonesian government represented by PT. PLN (State Electricity Company) will continue to maintain, operate and maintain old hydropower plants. So far, the development and development of PLTMH in Indonesia still uses consultants / contractors and its manufacturing is from overseas, even components (spare parts) are also still dependent on the technology producers themselves, the majority of which are foreign countries. Imports cannot be avoided, this results in us being vulnerable to several things, fluctuations in foreign exchange rates, and dependence on foreign producers. But with the increasing understanding of national resilience, especially in terms of national industrial independence, several national companies began to carry out reconstruction and fabrication for hydroelectric power plants. This is encouraging the author to learn to know, understand, how to plan the main parts of the Kaplan Turbine which include: runner, shaft, spiral casing, stacker, draft tube. In this plan the author focuses on calculating the main dimensions of the Kaplan Turbine. From the results of the design and calculation, the appropriate type of turbine is Kaplan Turbine as an electric generator drive in Plumbungan PLTM with installed power of 1.2 MW, maximum head of 21.16 meters and water discharge requirement of 7.68 m3 / sec. Plumbungan PLTM installation consists of turbines, turbine supporting equipment, and turbine operation aids. The turbine installation component consists of: suction pipe (penstock), turbine house (spiral casing), runner, runner shaft, shaft support bearing and draft tube.

Abstract

Major role in the valve spring Diesel 4 strokes is able to guarantee the valve open and closed positions without loss of engine compression. Therefore, the spring must be able to maintain the style required by the valve in accordance with the needs of its operations. When the spring force reduction operations over the threshold, then the spring will be malfunctioning. Before this happens, the spring should be replaced or restored. Meanwhile, the replacement with a new one because it failed to cause unplanned downtime. To balance the needs of utilities and prevention of failure (downtime) is required prediction faill replacement, and therefore the rate of decline in the spring force is directly related to the characteristics possessed by every spring, then to determine the rate of decrease in the valve spring force necessary to test fatigue characteristics. To achieve these objectives, characteristics and fatigue testing is done with spring material Goodman line approach. These tests include the identification of test material in the form of a test spring spring material chemical composition and hardness test; namely to determine the tensile strength limit in the diagram Heigh and criteria preset limit or unpreset spring tired. Next proceed to test the rate of decrease in the spring force on the cyclic loading which is the subject of this study, in which the rate of decrease in the spring force test due to cyclic done to reach the threshold spring force on the round number above 107. The test results showed that the decrease in the spring force caused by the spring force on the rate of decline of about 6% cyclic loading is at about 300 hours of operating hours, the next spring force experienced stability.
