The diseases are the results of a bad diet and free radicals. Rice bran is one of the food sources containing high fiber and antioxidants. However, it is rarely used as a food product. Rice bran may become the ingredient of patisserie products for NCD diet. These rice bran-based patisseries are made in the Food Engineering Education study program of the Faculty of Engineering at UNY. Through Project-based Learning (PjBL), the fourth-semester students taking the Bakery Processing course learned how to make rice bran products. There were 30 students participating in this research which was conducted from June to September 2018. Based on the result of this study, it was found that the average of students’ knowledge pre-test score was 20.90, and the posttest average score was 23.10. In terms of students’ attitudes, the average pre-test score was 46.25, and the average post-test score was 49.80. The students’ skills at making rice bran-based patisseries are considered “Good” because the score ranges between 93 and 100. PjBL is considered effective to be implemented in the Food Engineering class because it can improve students’ knowledge, attitude, and skill scores.","PeriodicalId":55675,"journal":{"name":"Jurnal Pendidikan Teknologi dan Kejuruan","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88512193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The high use of fossil fuels will harm the environment, therefore to reduce the use of fossil fuels, it is necessary to develop renewable energy power plants, one of which is a solar photovoltaic power plant. This study discusses the economic analysis of planning a soalr photovoltaic power plant at the Taman Melati Depok Apartment which is connected to the PLN network with the PVsyst software. This PLTS plan will be built on the roof of the apartment using an area of 437 m2 with generated power of 90,400 Wp. Using solar modules with a capacity of 565 Wp as many as 160 modules. This PLTS can generate electricity per year 116600 kWh/year. The Cost of Energy (COE) for this PLTS is Rp.735.39/kWh. Economic analysis uses Net Present Value (NPV), Profitability Index (PI), and Discounted Payback Period (DPP) to determine whether this PLTS is feasible or not. Based on the calculation result, the NPV value is Rp. 608,793,939.29, while the PI value is 1.587 and the DPP value is around 12 years and 9 months, which is faster than the project age, which is 30 years.

To operate according to its specifications, the load is increased by operating the load bank. The small internal load and use of the loadbank cause the cost of generation to be high. Excess generating capacity can be sold to external consumers outside the mining area, so it is necessary to build one circuit overhead transmission line 150kV as long 48.38km. The construction of overhead transmission line 150kV from the PLTU to the external consumer substation can increase sales of electricity and can replace the loadbank function. This study aims to evaluate the technical feasibility and economic aspects of the construction overhead transmission line 150kV from the PLTU to an external consumer substation. The research method uses financial indicators IRR, NPV and ROI. Overall, the construction of one circuit overhead transmission line 150kV can increase sales of electricity and replace the function of load bank.

The magnitude of the impact of methane gas emissions on global warming from the waste sector, it is necessary to calculate the potential amount of methane gas emissions of Padang city waste in the Air Dingin Landfill so that it can be used for new energy potential as an alternative energy to replace fossil fuels no longer as a contributor to global warming. In this study, the methodology contains systematic steps in researching to achieve research objectives, namely conducting preliminary studies and literature studies, formulating problems, and setting research objectives as well as how to collect and obtain research data. The result of this study is that the Air DIngin Landfill in Padang City is still processing open dumping, with land that has been operated around 50% of the existing land area. The high operational costs are one of the reasons the sanitary landfill system cannot be done by the Padang City Government. Methane gas produced from 2020 - 2031 in the Air Dingin Landfill is produced from scenario 1 (waste directly landfilled) which is 43,289 gigagrams of CH4 or 43,289 tons of CH4 emissions. CH4 emission scenario 2 (waste reduction by waste pickers in landfill) produced 43,267 gigagrams or 43,267 tons of CH4. CH4 emission scenario 3 (Reduction of waste at source, in the region, and in landfill) produced 40,944 gigagrams CH 4 or 40,944 tons of CH4.

Poor power quality in the electric power system can cause medical equipment in health care centers to malfunction and give incorrect medical diagnoses. Since 2020 we are facing a new type of Virus (Covid-19), this virus requires special laboratory construction with specific air conditioning systems (temperature, humidity, and pressure) to process specimens. This paper presents measurement results of harmonic distortion characteristic by Variable Frequency Drive (VFD) of Heating Ventilation Air Conditioning (HVAC) system in PCR Laboratory at Clinic A. The VFD in this system is used to adjust the rotation of the exhaust fan and outdoor unit. The measured voltage, current and power are used to assess power quality. The main power quality problems found in medical facilities are voltage flicker, neutral currents, and total harmonic distortion (THD) values. The measurement of total harmonic distortion (THD) is used to find the source of the harmonics. Potential problems can be identified within the facility.

In 2020, in April and September, floods occurred in the West Pasaman district, more precisely around the Nagari Ujung Gading area, Lembah Melintang District. Floods most often inundate the Jorong Lombok and Jorong Irian areas. The flood that occurred was caused by the overflow of the Batang Bayang river. Puddles of water inundated at least 150 residents' houses until the water level reached a height of 1 meter. The problem of flooding almost every year is felt by residents who live near the location of the Batang Bayang river. This study aims to determine the flood discharge of the Batang Bayang river with return periods of 2, 5, 10 and 25 years. Then this study also aims to determine the ability of the Bayang Bayang River to flow flood discharge for 2, 5, 10 and 25 years return periods. The results show that the 2-year return period produces a maximum flood discharge of 47.2 m/s3. In the 5-year return period it produces a flood discharge of 110 m/s3, in the 10-year return period it produces a flood discharge of 143.6 m/s3 and at the return period of 25 years resulted in a flood discharge of 189.2 m3/s. The cross section modeling in the 2 year return period resulted in a water elevation of 21.07 meters. The 5-year return period modeling results in a water level elevation of 22.4 meters. The 10-year return period models the water at an elevation of 23.01 meters and the 25-year return period produces a water level of 23.72 meters.","PeriodicalId":55675,"journal":{"name":"Jurnal Pendidikan Teknologi dan Kejuruan","volume":"181 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83019984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
