Abstract

This study intended to create a sea wave simulator to find out the potential of ocean wave power plants. To achieve the objective, this study used two systems: generation and reading. Generation used a DC motor as a drive from sea waves, while readings employed an IMU-GY86 sensor for readings of altitude and energy potential generated. The result of this study is that air and air pressure affect the results of measuring the wave height of seawater. Air pressure is inversely proportional to the elevation of a place: the higher the area, the lower the air pressure. The highest potential energy density of seawater waves amounts to 2405.33 J/m2, and the lowest was 550.18 J/m2, with an average value of seawater wave density energy of 1342.41 J/m2.

Abstract

IoT devices can range from smart home devices such as thermostats and security systems to industrial control systems used in manufacturing and other industries. One focus of the IoT-based monitoring and control concept is monitoring and controlling water heaters based on IoT technology to support the creation of a smart home. The purpose of this research is to create a system that can control and monitor water heaters remotely using the Android Studio application so that the water temperature in the heater can be ensured for safety, comfort, reliability, and energy efficiency. The system is designed using temperature sensors and water flow sensors, and then the data is processed with the NodeMCU microcontroller and then sent to the Firebase website to be displayed on the application. The application built can set a large amount of water and heat it to the desired temperature before sending it to Firebase and then to NodeMCU. The result of this research is an application that is able to control and monitor a water heater with an average measurement difference of 0.38 liters and an average error percentage of 7.11% The relay control system in the application has an average delay time of 3.6 seconds.

Abstract

Batik coloring still uses synthetic dyes, so the disposal of coloring waste should not be careless. Most batik craftsmen process their batik waste by settling the waste liquid for a long time. The process is very ineffective. The purpose of this research is to design a batik processing tool that is cheap and effective. The research method uses the electrocoagulation method. The electrocoagulation method is an electrochemical water treatment. The design of this batik waste treatment tool consists of five parts including: (1) Electrocoagulation Tub, (2) Skimmer, (3) Electrode, (4) Sand Filter, and (5) Studge Drying Bed. This tool works with 900 watts of power with an output of 20-40 volts DC. The capacity of liquid waste is 50 liters. Duration of waste treatment for 2 hours. The electrocoagulation method is able to reduce the values of BOD5, COD, TSS, and TDS in batik dye waste. The pH of wastewater which is still high can be reduced by giving alum.

Abstract

Desa Ujungmanik Kecamatan Kawunganten Kabupaten Cilacap yang berada di area Segara Anakan Cilacap memiliki sumber daya alam khususnya tanaman kayu putih yang berpotensi untuk mengembangkan perekonomian masyarakat desa. Permasalahan terbesar yang dihadapi oleh LMDH Dadi Makmur sebagai unit yang mengelola bisnis minyak kayu putih yaitu setelah produksi penyulingan minyak kayu putih akan menghasilkan sisa limbah dari ranting dan daun minyak kayu putih dengan volumenya cukup besar dan hanya dibiarkan ditumpuk di sekitar halaman tempat penyulingan sehingga menyebabkan area penyimpanan bahan baku mentah minyak atsiri menjadi sempit dan juga membutuhkan waktu yang lama untuk menjadi pupuk organic. inovasi yang ditawarkan melalui kegiatan pengabdian masyarakat ini adalah mengimplementasikan mesin pencetak briket dari limbah penyulingan minyak kayu putih yang hemat energi berbasis panel surya. Hasil pengabdian menunjukkan bahwa kegiatan pengolahan limbah minyak kayu putih selain mengurangi pencemaran lingkungan, juga menghasilkan briket biomassa yang dapat dimanfaatkan oleh warga Desa Ujungmanik sebagai produk ekonomis unggulan Desa Ujungmanik.

Abstract

Penelitian ini menginvestigasi sistem pengolahan data yang berbasis pada integrator Ramsey Micro Tech 9101 dalam konteks penggunaan Belt Scale di jalur konveyor CC.10 TAL PT Bukit Asam Tbk. Belt Scale adalah alat penting dalam industri pertambangan yang digunakan untuk mengukur berat material batubara yang mengalir di atas konveyor. Sistem ini memungkinkan penimbangan yang akurat dan efisien untuk tujuan produksi dan distribusi. Proses pengolahan data dimulai dari sensor transduser Load Cell, yang membaca sinyal input analog yang merepresentasikan berat material batubara yang terukur. Dalam sistem ini, Speed Sensor juga berperan dalam memberikan data kecepatan dan jarak lintasan belt conveyor. Data dari sensor tersebut diolah oleh integrator Ramsey Micro Tech 9101, yang mengkonversi sinyal analog menjadi data digital yang mencerminkan berat material batubara yang diangkut. Langkah awal dalam sistem pengolahan data melibatkan pengambilan parameter atau data yang diperlukan sebelum dimasukkan ke dalam integrator. Setelah data terkumpul, dilakukan tahap pengolahan data dan pengujian dengan beban statis untuk memastikan ketelitian timbangan. Proses kalibrasi melibatkan zero calibration dan span calibration, yang membantu memastikan akurasi pengukuran. Penelitian ini membuktikan bahwa integrator Ramsey Micro Tech 9101 berperan krusial dalam mengubah sinyal analog menjadi informasi digital yang akurat. Sistem ini memiliki implikasi yang signifikan dalam meningkatkan efisiensi dan ketelitian dalam pengukuran berat material batubara pada konveyor.

Abstract

Cilacap Regency is a coastal area south of the island of Java. The purpose of this study is to determine the potential of raw materials available in the South Cilacap Coastal area and to determine the potential power that can be generated for the PLTH system through the calculation of the raw material data that has been obtained. This research method begins with direct measurements of wind speed and light intensity. Both devices read data in real time and connect online. The data obtained is processed to determine the wind speed and the average intensity of sunlight. The results of these calculations are entered into the equations to calculate the potential power that can be generated. Based on the calculation, the average wind speed is 3-4 m/s and the light intensity is 54612 watt/m2. The results of the calculation of the potential power that can be generated from the PLTB system in the coastal area of ??South Cilacap is equivalent to 508 watts/day. The potential power that can be generated from PLTS is 10.8 kW/day. The total potential power that can be generated from the PLTH system on the coast of South Cilacap is equivalent to 273.22 kWh/day.

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.
