Abstract

Air merupakan sumber daya alam yang menjadi salah satu kebutuhan utama dalam kehidupan dan sampai saat ini belum ada senyawa lain yang dapat menggantikannya. Sulitnya mendapatkan air yang berkualitas saat ini masih menjadi problem di beberapa daerah. Masyarakat yang memanfaatkan sumur sebagai sumber kebutuhan air pun terkadang masih mengalami masalah pada kualitas air yang dihasilkan sumur tersebut. Air yang belum layak digunakan khususnya dikonsumsi harus diproses terlebih dahulu, misalnya proses filtrasi. Penelitian ini merancang bangun sebuah sistem penjernih air menggunakan sistem filtrasi yang dapat secara otomatis memfiltrasi secara berulang jika air hasil filtrasi masih melebihi batas nilai kekeruhannya. Sistem filtrasi menggunakan bahan pipa PVC sebagai tabung reaktor filtrasinya dan beberapa bahan penjernihnya yaitu karbon aktif, pasir manganese dan kapas. Sistem penjernih dilengkapi dengan sistem monitoring yang dapat menampilkan nilai kekeruhan air melalui aplikasi Blynk. Beberapa perangkat elektronik yang digunakan yaitu esp32 sebagai kontroler, sensor turbidity untuk mengukur kekeruhan air, sensor ultrasonik untuk mengukur level air pada bak penampung serta pompa DC untuk mengalirkan air dari bak penampung ke reaktor filtrasi. Berdasarkan pengujian sistem filtrasi, menunjukkan bahwa sistem penjernih dapat menjernihkan air dengan tingkat penjernihan sampai dengan 47,56 %. Status air yang diproses filtrasi dapat dimonitoring melalui aplikasi Blynk sesuai dengan perancangan. Informasi bak penampungan air dan nilai kekeruhan air dapat ditampilkan pada aplikasi Blynk dengan baik. Selain itu, pompa air yang terdapat sistem penjernih dapat dikontrol secara manual melalui aplikasi Blynk yang digunakan.

Abstract

A coil winding machine for water pumps using a monitoring system is a development of conventional winding tools. In regular coil winding tools, the coil winding process is done manually by rotating the handle as many times as the desired number of turns. The conventional winding tools have problems consisting of inconsistent working speed and operator-dependent winding continuity. Undesirable windings can occur with conventional winding tools, and the winding process requires close supervision. Therefore, the automatic coil winding machine was developed to optimize the coil winding process. The machine utilizes a DC motor to rotate the coil rolls, replacing the conventional roller handle function. This machining method uses an optocoupler sensor. The sensor serves to identify and evaluate the rotation of the roller. In addition, the ATmega8 microcontroller was applied to develop a system that can work automatically. Data collection involves varying the number of wire turns and the wire diameter dimension. The variation is necessary because the number of windings and wire diameter affect pump efficiency and performance. The data testing showed a machine accuracy rate of 98%, with a maximum difference of 1 coil winding in the results. This data confirms that the coil winding machine meets the tool's accuracy standards.

Abstract

The need for electricity is increasing along with population growth. The main electricity supply (PLN) is not always continuous in its distribution, so alternative power is needed, namely generators. The ATS (Automatic Transfer Switch) system can transfer the voltage source to the load. The ATS system is equipped with IOT in the form of a Blynk application on Android which functions as a controller and can send ATS damage notifications. This research was conducted to meet the electricity needs. Users can monitor, control and maintain the ATS system in the event of a breakdown. The method in this study uses a quantitative method, namely data collection by testing the ATS system and testing the IOT Blynk application function as a notification of damage to the ATS system. The result of transferring the PLN voltage to the generator is only 7 seconds and 3 seconds vice versa. There was damage to the lamp cable 1 time, the relay 1 time, and the fan cable 2 times. The results of measuring the current and voltage of the PLN source: lamp load 0.02A, 3.4V; fan 0.04A, 3.5V; AC motor 0.04A, 4V. Generator current and voltage measurements are as follows: lamp load 0.02 A, 9.1V; 0.03A, 9V fan; AC motor 0.05A, 4.5V.

Abstract

Indonesia is an agricultural country with 40% of the population's livelihood provided by farmers. Harvested rice typically has a moisture content of 20-27% on a wet basis. The type of artificial dryer that is often used is the tub or rotary type. This research aims to develop a rice dryer using a combined tray and rotary-type method. Based on the result, the higher the speed dryer, the shorter the drying time. The net result of this test is that the relationship between time and engine speed is inversely proportional. The higher the speed, the shorter the drying time. The net result of this test is that the relationship between time and engine speed is inversely proportional. Rice drying results can be described as dry, but not including ready-to-eat rice standards. The higher the speed, the shorter the drying time.

Abstract

Technological developments in materials are increasingly evolving, one form of development is the type of composite insulation. One of the natural fiber composites currently available is a composite from palm fiber which provides increased dielectric strength. Partial discharge due to voids in the composite results in structures such as electrical treeing due to changes in the properties and morphology of the composite causing increased insulation failure and disrupting power distribution. This research tested the strength of Epoxy composite insulation and palm leaf ash filler. By combining these two materials, a complementary composite insulating material will be formed to prevent electrical treeing. The results of the research show that the composite insulating material with nipa palm fiber as filler has an average breakdown voltage value of 40 kV and is above the standard breakdown voltage value for medium voltage insulators of 30 kV. The addition of more and more palm leaf ash filling material will produce voids, thereby accelerating the occurrence of electrical treeing and decreasing the breakdown voltage of the insulation.
