Abstract

Condensing type geothermal turbine is a mechanical device that used to convert thermal energy into mechanical energy, then after converted to electrical energy in the generator by the rotation of the rotor’s magnetic field. Development of blade material for geothermal turbine application which using local content is crucial due to the blade’s turbine are 100% imported. So, efforts to produce blade material with high local content are very strategic to support national energy independence in the future. The Agency for the Assessment and Application of Technology (BPPT) started from 2020 until 2023 will focus on the development of the blade material for geothermal turbine application. As a starting point of the research, modelling and virtual testing of the stage-1 blade turbine were performed. In this study, the model is done in CATIAV5 software. Solid model is then imported to ANSYS workbench 15.0. Thermal-Structural analysis of turbine blade using the Stainless steel-based alloy with the ANSYS workbench 15.0 was carried out. In the thermal analysis, the model is given temperature, convective heat flux transfer coefficient and atmosphere gas temperature and then is solved for the heat flux distribution over the blade surface. The obtained heat flux distribution is taken as the thermal load into the Static structural analysis. In the static structural, the obtained model is given structural load, namely centrifugal force. The model is then conducted virtual testing in order to obtain stresses and deflections. The results showed that the model of stage one blade turbine is safe when operating at the determined loads.

Abstract

Many people use rotten / unfit fruit to make liquid compost with fruit aroma to fertilize their plants, processing fruit that is not suitable for use which will be reprocessed to reduce fruit waste in anticipation of health problems, especially when rotten fruit is thrown away Careless places will cause problems for public health however, their tools are not efficient for processing the fruit because the cutting process is still using a kitchen knife so that the production of fruit which is made into liquid compost is slow in production, so a liquid compost machine from fruit waste is needed to speed up production making compost and making more production and processing faster. The purpose of this study was to design a manufacturing process based on the design drawings of a liquid compost machine from fruit waste. The method used is Design for Manufacturing and Assembly (DFMA). The output of this method is a Standard Operational Procedure (SOP) document and an Operation Process Chart (OCP). Based on the calculation results of the liquid compost machine manufacturing process design, the net estimate of manufacturing process time is 392 minutes with a total of 66 activities consisting of operation, assembly and inspection activities.

Abstract

The increase in the use of electrical energy in Indonesia is currently increasing from year to year and the population in Indonesia is increasing very rapidly, therefore we need an energy utilization technology that does not need a lot of money to operate it. Because Indonesia is located on the equator which makes Indonesia has a great potential for sun exposure. Utilization of solar energy can be done by using a technology to generate electricity from solar energy sources, namely Concentrated Solar Power (CSP) technology. Concentrated Solar Power (CSP) is a technology that uses solar energy that produces electrical energy from a component that converts heat energy into electrical energy using a Stirling engine. In this research, the solar energy utilization device developed is a Ground Base type Concentrated Solar Power (CSP) device equipped with a liquid fluid delivery system in the form of a piping system and a Stirling engine. By using a satellite dish measuring 6 feet or 1830 mm, and also added a drive system to move the parabola according to the point of efficient solar heat reception.

Abstract

In the current technological development, the electric motor is the most popular in various industrial applications. Electric motors today have evolved very quickly and have a significant impact on the lives of the wider community. The use of environmentally friendly and efficient energy is one of the reasons why this motorbike has become a pioneer of technological advances, especially in the automotive world. This research focuses on conducting a comprehensive analytical study on one type of electric motor, namely synchronous because it is widely applied in various conditions today.

Abstract

The current becomes a factor influencing the hardness value In the welding. The higher the welding current would affect the higher the hardness test results. If the current were used is low it will make it difficult to ignite the electric arc. Aims of this study to determine the effect of welding current (90, 110 and 130 A) and buffer layer on hardness, macro and microstructure layers are result from hardfacing using AWS A5.13 EFe2/AWS A.51 E7018 elektrodes. The hardfacing process uses a Shielded Arc Metal Welding (SMAW) welding machine with DC+ polarity. Hardfacing consists of three layers, 1st layer uses AWS A5.13 EFe2 electrode, 2nd layer uses AWS A.51 E7018 electrode, and 3rd layer uses AWS A5.13 EFe2 electrode. The increase in hardness will occur significantly after hardfacing on the base metal. The higher welding current is resulting the higher hardness value. The hardness of the 130 A specimen is higher than 90 A and 110 A specimen. In the 130 A specimen the hardness value was 468.1 VHN, and in the 90 A specimen the hardness value was 358.94 VHN.
