Abstract

Tujuan dari penelitian adalah  mempelajari apakah ada pengaruh  lamanya  umur instalasi listrik kepada  frekuensi terjadinya gangguan .pada  instalasi listrik di rumah tinggal.Pada pemakaian instalasi listrik yang sudah lama ada kemungkinan terjadi gangguan terhadap instalasinya itu sendiri, yang disebabkan karena usia dari instalasi terutama kabel penghantarnya. Metode yang digunakan adalah survey lapangan dengan mengambil sampel di kompleks perumahan dalam hal ini adalah Perumnas Tlogosari di kota Semarang. Alasan pemilihan lokasi ini karena lama perumahan ini dibangun dan dihuni sudah lebih dari 30 tahun, sehingga layak untuk dijadikan sampel penelitian. Pengumpulan data dilakukan dengan kuesioner, sedangkan metode analisis data menggunakan analisis deskriptif-kuantitaif, Hasil yang diperoleh dari uji hipothesa adalah bahwa hipothesa nihil yang menyatakan bahwa tidak ada pengaruh tentang umur instalasi listrik terhadap terjadinya gangguan ditolak, yang berarti hipothes kerja diterima, arinya memang ada pengaruh umur instalasi terhadap terjadinya gangguan. Usia instalasi yang sering terjadi gangguan adalah antara 21 tahun sampai dengan 30 tahun, sedangkan yang jarang  terjadi adalah pada usia instalasi antara 10 sampai dengan 20 tahun.Kata kunci : gangguan, instalasi listrik, survey.

Abstract

Oil cooled power transformer has important role in the electricity distribution system. Its windings were immersed in oil as an insulating medium and also as a cooler. This oil would be heated up due to several things, the most significant was heat generated by winding’s power loss. The monitoring of oil temperature on the transformer was always done routinely every day to maintain its performance and health condition. IoT based measurements could improved efficiency and minimized manpower resources. To realize this the indirect non-destructive measurement method was proposed to estimate transformator’s temperature oil. It will corellate the oil temperature and body temperature through a constant calibration factor derived from calculations. Conducted experiment applied to specific existing transformator and followed by calculations resulted a calibration factor = 1.7749. The smallest average of estimated temperature error was lied in the range of 40 - 90 degrees Celcius.

Abstract

GY-521 MPU-6050 Module is a core module MPU-6050, which is a 6 axis Motion Processing Unit. This sensor can be categorized as an Inertial Measurement Unit (IMU) sensor, which utilizes measurement systems such as gyroscopes and accelerometers to estimate the relative position, velocity, and acceleration of an object. A common accuracy problem in using IMU sensors, including the GY-521 MPU-6050, is the drifting phenomenon. This phenomenon results in a deviation between the actual conditions (position, angular velocity) and the sensor readings. Drift is caused by the accumulation of errors that arise from calculating the integral of the acceleration. This study proposes a drift error correction method at the sensor output using the calibration of the calculation of the average offset error sensor and the sensor fusion method between the information obtained from the gyroscope and accelerometer in the module, the tests were carried out using the Arduino Uno microcontroller. From the test results, it is found that the combination of the initial system calibration implementation and the use of the fusion sensor concept can provide better performance with the MSE analysis results for the roll position of 0.0029o and the pitch position of 0.0047o and the drifting error rate at the yaw angle position of 0 0082o / second or down 62.72%.

Abstract

Abstract— Agricultural development plays a role in providing food supply, maintaining food scarcity and maintaining food prices so as not to fluctuate and evenly distribute food, becoming a major problem in each region. Banten Province with regional potentials that have a surplus of food products and a wide area that is adequate has the potential to develop a food distribution center. The aim of a food distribution center is to meet food supply chain chain throughout the region, avoid food scarcity, stabilize food prices and maintain price disparities thus they can be properly met. The role of food hubs is to aggregate, distribute and market food at the farmer, trader level, and to function the role of the BUMD in realizing the operation of the food distribution center. Short food supply chain chains cut costs of crop production in farmers, food distribution costs and transportation costs from farmers to distribution centers. Government policies through relevant local government agencies must be able to move the role of stakeholders in this case farmers, traders, distributors, transportation services in realizing the operation of the food distribution center to provide food procurement services and able to provide welfare levels, especially small farmers as producers in the supply chain of food products.

Abstract

Raw material in cement production is a source of natural wealth that is not renewable, namely limestone, silica sand, clay and iron sand. This situation causes the cement productions damage environmental sustainability. Based on this phenomenon, the researchers tried to find other materials that are like cement (cementitious material). According to previous researchers, rice husk ash and slag contain silica in sufficient quantities so that it can be used as a substitute for cement. Therefore the purpose of this research is to use both organic and inorganic waste materials as cementitious materials that are like cement. The research conducted was experimental research. Rice husk ash and slag as cementitious material are examined for chemical characteristics and physics. Test specimens in the form of cement paste are divided into two types, namely control specimens (without rice husk ash and slag) and treatment specimens (husk ash and slag as much as 2.5% - 15% of the weight of cement). Tests performed on cement paste are normal consistency and setting time. Based on the results of normal consistency and setting time, the mixture of rice husk ash and slag can be categorized as cementitious material.

Abstract

The rice supply chain process starts with farmers who harvest rice and sell it to Regional Owned Enterprises (BUMD) through Bank BJB and Bank Banten based on a price agreement. The rice is then processed in the Rice Milling Unit (RMU) to become ready-to-process rice, before being sent to the warehouse receipt as a guarantee of economic value. From the warehouse receipt, rice is sent to the distribution center which functions as a stock buffer and price determiner, then distributed to consumers. The distribution problem is less than optimal and rice is often sold outside the region, then back to regional distributors, causing an imbalance between food needs and availability. This research aims to illuminate supply chain management in distribution centers and the facilities used in the process. To reduce distribution costs, the transportation method uses the Vogel Approximation Method (VAM) and MODI is used to find the minimum distribution costs. The research results show that the minimum distribution costs in 2017 were IDR 1,024,557,000,000, in 2018 IDR 1,024,107,000,000, 2019 IDR 1,020,428,000,000, 2020 IDR 1,089,830,000,000, and 2021 amounting to IDR 1,111,159,000,000.
