Abstract

Province of the Bangka Belitung Islands has the potential for palm oil commodities which contribute to the economy. Palm oil processing produces biomass waste such as shells, fibers, and empty fruit bunches. Biomass in the Province of the Bangka Belitung Islands has a potential of 217.7 MW. CO₂ emissions are mostly from burning fossil coal where the CO₂ produced is dangerous. Alternatives are needed to reduce these CO₂ emissions. One of them is biomass. This plan uses a forecasting method to get an estimate of the energy potential of palm oil waste in 2022-2032 in the Province of the Bangka Belitung Islands and CO₂ emissions generated from palm oil waste energy. By using modeling, evaluating methods, forecasting, and calculating energy potential as well as CO₂ emissions from biomass, it can be concluded that the projected energy potential of palm oil waste from 2022 to 2032 will increase every year and can help fulfill regional energy requirements for the Bangka Belitung Islands Province. In 2025 the energy produced by 15.29 thousand TOE can help meet the energy requirement of 27.91 thousand TOE 2025. In 2030 the energy produced by 28.12 thousand TOE can help fulfill 46.79 thousand TOE of energy 2030. CO₂ emissions The amount of biomass from palm oil waste in 2022-2032 is increasing every year along with the increase in energy produced from palm oil waste biomass. Keywords: oil waste energy, biomass, energy, CO2 emissions

Abstract

Current Transformers (CTs) are essential components in power system protection, ensuring accurate current measurement for relay operations.. This study evaluates the accuracy of protection CTs used in 20kV feeders at the Bangka Transmission and Substation Service Unit. Measurements were conducted on CTs with 5 and 7 years of usage to analyze ratio error and knee voltage compliance with IEC 61869-2 standards. The results indicate that all CTs meet the standard, with ratio errors below 1% and knee voltages exceeding 60V. Normality tests confirmed that the data are normally distributed, allowing statistical analysis using t-tests. The t-test results showed no significant difference in ratio error and knee voltage between CTs used for 5 and 7 years. This study concludes that aging over this period does not significantly affect CT accuracy, ensuring continued reliability in power system protection.

Abstract

Minum merupakan proses manusia memenuhi kebutuhan tubuh dalam hal cairan karena 70% tubuh manusia terdiri dari kandungan air. Kebanyakan manusia tidak mengetahui jumlah air yang harus diminum dalam sehari sesuai dengan umur dan berat badan atau sesuai dengan jumlah yang dianjurkan untuk kesehatan tubuh manusia. Oleh karena itu, pembuatan sebuah alat untuk membantu manusia dalam mengatur pola minum yang tergantung dengan aktivitas dan fisik manusia tersebut sangat perlu dilakukan sehingga alat tersebut dapat membantu manusia dalam mengetahui jumlah cairan yang diperlukan serta untuk mencegah penyakit terutama dehidrasi akibat kurangnya minum air. Hal ini memberi gambaran bagi penulis untuk membuat sebuah teko minum cerdas yang dapat membantu kesehatan manusia. Teko minum ini akan terintegrasi dengan perangkat elektronik dengan beberapa sensor sebagai pengukurnya. Seperti sensor pH untuk mengukur pH air karena memengaruhi kesehatan manusia, sensor ultrasonik untuk mengukur jumlah air yang telah diminum oleh manusia, dengan mikrokontroler untuk mengatur pola minum dan mengukur kebutuhan cairan yang dibutuhkan oleh manusia secara spesifik. Banyak di pasaran produk teko air minum cerdas atau smart water jug, tetapi hanya sebatas menghitung mundur pola minum dan kapasitas air di dalam wadah. Teko air minum cerdas yang di bangun merupakan sebuah terobosan pengaturan kebutuhan cairan seseorang dengan postur fisik dan aktivitas yang spesifik serta pengaturan secara otomatis kadar cairan dalam tubuhnya dan diharapkan dapat menjaga kesehatan tubuh dalam mengatasi kekurangan cairan serta mencegah dehidrasi dan mungkin penyakit ginjal akibat sering kurangnya minum air

Abstract

Drying is a process of transferring heat and water vapor simultaneously which requires heat energy to evaporate the water content. This heat energy can usually be obtained from sunlight. However, during the rainy season, this condition inhibits the drying process that utilizes sunlight, so the drying process takes a long time. Therefore we need a tool that can dry clothes without depending on the heat source from the sun's rays. The clothes dryer is a tool used to dry clothes with artificial heat energy, one of the artificial heat producers is a heating element or what is often called a heater. The artificial heating element used in this research is Electric Heater. This Electric Heater is equipped with a fan that can produce an indoor temperature of up to ± 52.3º C so that the heat generated by the Electric Heater can convert the water contained in the clothes into water vapor which will then be released into the environment with the help of a fan. Based on the results of calculations and testing, the ability of this tool is able to evaporate an average mass of water of 535.8 grams/hour and this machine reaches its optimum point for the number of drying clothes that can be dried as many as 6 clothes.
