Using solar panels as a power plant can reduce the dependence of fuel oil. To work always on maximum power points, Photovoltaic (PV) requires optimization method. For this reason, the authors are interested in discussing the optimization method of the PV array model using Maximum Power Point Traking (MPPT) with the Perturbation & Observation (P & O) Algorithm and Boost Converter. In this case, …

Penentuan Lokasi Tempat Pembuangansementara (Tps) Di Kecamatantampan Mengguna…

The large number of population is directly proportional to the amount of waste in an area, so that a temporary disposal site (TPS) is needed that can accommodate daily waste but the problem that occurs when wanting to build a polling station is where the polling station will be built. To give a recommendation for the location of the TPS construction the data is processed using the Centroid K-Me…

Alat Ukur Panjang Bayi Berbasis Linear Encoder

Babies are 0-12 month individuals characterized by growth. The process of measuring the baby is done manually with a long time. Therefore, to measure the baby's length a linear encoder-based baby length meter is equipped with an LCD. LCD on this device is used to display the baby's length measurement. This tool is equipped with Arduino Uno as a microcontroller. This tool uses Linear Encoder as …

Timbangan Bayi Berbasis Sensor Load Cell

Baby Scales is a tool used to measure a baby's weight from newborn and how its development. By knowing the baby's weight, it can be indicated how the baby's health is in accordance with the normal or incompatible baby development table. Baby scales is commonly used in Posyandu or hospitals still use analog scales, so the measurement results obtained are less accurate. Load cell sensor based bab…

Rancang Bangun Sistem Monitoring Ph Air Kolam Pembibitan Ikan Patin Menggunak…

Design of monitoring ph pool water of catfish breeding using GSM 900A module on arduino. The purpose of this research is to design a monitoring system to support catfish breeders in knowing the acidic and alcali pH levels water. Arduino Nano is a programmable tool for processing water pH sensor reading data. The workings of this tool is, when the pH sensor which is an input is put in water, the…

Pengaruh Pemberian Pakan Cacing Sutera (Tubifex Tubifecx) Terhadap Pertumbuha…

Baung fish (Hemibagrus nemurus) is one of the main targets in fishing by fishermen. As a result, the fish population has declined. To improve the survival of baung fish larvae, it is necessary to add nutrients such as probiotics and tofu dregs. Among the doses used in feeding larvae of this baung fish are 0,3 mg/3 gr feed, 0,6 mg/3 gr feed, and 0,9 mg/3 gr feed. The aim of the study was to anal…

Ekstraksi Polietilena Dari Limbah Kertas Laminasi Dengan Variasi Suhu Dan Wak…

Laminated paper is paper that is coated by a layer such as plastic, aluminum foil and others in order to protect the paper from various contaminants and is resistant to water. Laminated paper is usually discarded or not reused, so that laminated paper can be recycled and reused, it is necessary to separate the paper and polyethylene from the laminated paper. The separated polyethylene can be re…
