Abstract

Pondok Pesantren (Ponpes) Mambaul Ulum Desa Punggur Kecil Kecamatan Sungai Kakap Kabupaten Kubu Raya, belum tersentuh akan air bersih  atau standar air layak untuk dikonsumsi. Ini semua dikarenakan belum meratanya pengadaan infrastruktur, karena terbatasnya anggaran pemerintah dan biaya yayasan sehingga menjadi faktor penghambat dari tersedianya air bersih bagi warga ponpes. Untuk mengatasi permasalah tersebut maka dilakukan kegiatan pengabdian pada masyarakat dengan tujuan yaitu meningkatkan pengetahuan tentang standar kualitas air bersih dan keterampilan pengolahan air layak konsumsi warga serta meningkatkan kesehatan dan kesejahteraan warga di Pondok Pesantren Mambaul Ulum. Adapun metode yang akan dilakukan yaitu kegiatan mencari melakukan pelatihan dan praktek langsung pembuatan sumur bor dan pengolahan air layak konsumsi yang nantinya akan dipasang dan dioperasikan. Adapun hasilnya warga diPonpes mengetahui standar air sesuai Peraturan Menteri Kesehatan Nomor 416/MENKES/PER/IX/1990, mengerti cara membuat sumur bor, penyediaan air dan penjernih air layak konsumsi dan kesehatan dan kesejahteraan warga diPonpes miningkat

Abstract

Wind turbines are one of the machines that are currently still used to convert wind kinetic energy so that they can be used by humans such as to drive pumps in agriculture and produce electrical energy. Savonius turbine is a vertical axis turbine that is currently widely used as an electrical energy generator, this wind turbine is a type of drag type wind turbine that has a simple design that is in the form of a semicircular curved blade side. Therefore, the author is interested in researching the resulting performance including turbine rotational speed, power generated, and wind turbine efficiency against the variation of the blade radius. The method used is experimental, the stages of this research are in the form of literature studies, making savonius turbines, testing savonius turbines with variations in blade radius as well as data retrieval, data processing, and analysis. Based on the data obtained, the rotating speed of the turbine is influenced by variations in the radius of the blade. The larger the blade radius, the smaller the turbine rotational speed. The maximum turbine rotation speed at blade radius 63 is 173 rpm, while at blade radius, 88 is 118 rpm and at blade radius 113 is 115 rpm. So the highest turbine rotating speed at a radius of 63.

Abstract

In this work, we propose the use of a low-cost PV monitoring system for providing accurate and comprehensive data required in the development of efficient and reliable solar PV plants. The system is developed based on an open-source Arduino platform with the capability to monitor solar irradiance, and electric outputs and temperature of multiple solar panels, which should enable the accurate assessment of solar energy resource, as well as electrical energy produced by PV plant under real operating conditions. To demonstrate its applicability, the system has been installed at the campus of Politeknik Negeri Pontianak in Pontianak City, and the data collected by the system is used to assess solar energy resource at the location. Data collected by the system from August 2020 to September 2021 shows that the values of solar irradiation are in the range of 2.9–4.1 kWh/m2 per day, and electric energy produced by commercial solar panels are in the range of 0.30–0.46 kWh/m2 per day, correspond to the monthly averaged efficiencies of 8–13%. The values of solar irradiation are 15–40 % lower than those obtained from the space-averaged satellite data which are in the range of 4.1–5.8 kWh/m2 per day. This shows the significant effects of local conditions, and confirms the advantage of assessment using the low-cost monitoring system that directly accounts for the effects of local conditions without the need of simulation using complex model and sophisticated software that required in the assessment using satellite-derived data.

Abstract

This study aims to repair damage to the Galdabini Type PM10 Universal Testing Machine (UTM) on a data acquisition system with an automatic system, design a conventional data acquisition system to a control system using the Arduino Uno AT Mega 328 microcontroller program and process the desired data and graphics with the help of the PLX application - DAQ Ms. Excel. This research uses the experimental method which is a basic framework used as a reference in conducting research which contains stages for solving problems in research. The research was conducted at the Materials Testing Laboratory of the Pontianak State Polytechnic Department of Mechanical Engineering by designing the input and output program for the PM10 Galdabini UTM data. In the tensile test, the output data displays force and addition data, a graph of the attraction and addition force relationship. While in Ms.Excel data obtained tensile stress, strain, modulus of elasticity, the proportion of changes in length and diameter, as well as a graph of the relationship between tensile stress and strain. In testing the compression output data displays force and shortening data, a graph of the compression and shortening force relationship. In Ms.Excel data obtained compressive stress, strain, modulus of elasticity, as well as a graph of the relationship between compressive stress and strain. In the bending test, the output data displays force and deflection data, a graph of the relationship between bending and deflection forces. In Ms. Excel, we get data on bending stress, modulus of elasticity, and graphs of the relationship between bending stress and deflection.  Kata kunci: arduino uno, PLX-DAQ microsoft excel , universal testing machine.

Abstract

Motorcycle users in 2019 reached 133,617,012 units in Indonesia. The impact of a large number of motorcycle certainly attracts the interest of the industry to produce two-wheeled automotive vehicles. The piston is part of the engine that functions as a compression barrier in the combustion chamber, the piston material is aluminum alloy. Therefore, research was carried out on making pistons with investment casting methods, physical and mechanical patterns from 3D printers on pistons. This research starts from drawing the piston using CAD (computer-aided design), making a printed pattern from a 3D Printer machine with PLA (polylactide acid) material. The mold pattern is coated with a mixture of gypsum cement and silica powder. The casting process with a pouring temperature of 750ᵒC and a mold temperature of 200 ᵒC, 250 ᵒC, 300 ᵒC, 350 ᵒC, and 400 ᵒC. The results showed the largest grain size at a mold temperature of 400ᵒC. The highest hardness at 200 ᵒC mold temperature is 47.00 HRB and the lowest hardness at 400 ᵒC mold temperature is 40.56 HRB. The higher the temperature of the mold used, the level of porosity of a material will decrease. This is due to the temperature difference when pouring the molten metal and the lower mold temperature. This makes the metal solidification time longer. The higher the mold temperature, the slower the solidification time, the larger the grain structure, and the decreased hardness.
