Abstract

Solar Tracking System (STS) merupakan salah satu cara esensial untuk meningkatkan efisiensi penangkapan cahaya matahari pada panel sel surya. Penelitian ini membahas tentang pengembangan STS pada sel fotovoltaik yang mempunyai dua sumbu putar (rotasi vertikal-rotasi horisontal) dengan perangkat pengendali berupa sebuah mikrokontroler dan algoritma cerdas Fuzzy Sugeno orde nol. Masukan sistem tersebut berasal dari 4 (empat) buah sensor cahaya Light Dependent Resistor (LDR) yang terdiri dari 2 (dua) sensor LDR untuk mendeteksi pergerakan matahari dari arah timur ke barat dan 2 (dua) sensor sisanya untuk pergerakan matahari di arah utara atau selatan. Keempat sersor tersebut ditempatkan ditepi sisi bagian luar dari sel fotovoltaik. Sistem ini menggunakan sel surya polycrystalline 10 Wp dan sebuah baterai berkapasitas 12 volt / 7,2Ah. Aktuator sistem ini berupa 2 (dua) motor DC servo bertorsi tinggi. Pengujian kinerja sistem ini masih dilakukan dalam skala laboratorium dengan bantuan cahaya lampu LED yang digerakan manual. Tegangan dan arus keluaran sel surya diukur menggunakan sensor tegangan dan sensor arus ACS712, dimana hasilnya disimpan pada sebuah komputer yang terhubung dengan sistem. Respon unjuk kerja sistem STS yang menggunakan Fuzzy sugeno orde nol memiliki efisiensi yang lebih tinggi 34,18 % jika dibandingkan dengan sistem sel surya yang statis.

Abstract

Product redesign strategies can reduce production costs and shorten design lead times in developing new variants. In the manufacturing design model, identifying the function of components based on customer demand and quality standards becomes vital information for enhancing product reliability, even though design reliability analysis needs to be more frequently addressed. The Design for Manufacturing & Assembly (DFMA) model has been implemented to simplify product structure, reduce risk and manufacturing and assembly costs, and analyze and identify improvement targets. DFMA has evolved into a philosophy for optimizing total production costs from the perspective of assembly, part design, and total life cycle costs. In many studies, the design and development of remanufactured products have been conducted with quality and compliant initiatives. The form and behavior of failure and repair activities obtained during the conceptual design phase have yet to be systematically considered as the basis for product design enhancements. Risk considerations and failure analysis have yet to be utilized as an integrated model during the product redesign phase. This study aims to evaluate the existing DFMA model and develop a new product redesign model and repurposed product with the integration of the Concurrent Engineering (CE)-based Redesign for the Manufacturing & Assembly model by considering reliability and risk factors. Incorporating the model concept is anticipated to contribute to a dependable, efficient design and reduce manufacturing expenses

Abstract

Boilers function to produce hot water or hot steam from combustion products to be converted as energy. Steam is used to drive turbines to produce electrical energy, apart from that steam is also used for heating. The boiler fuel uses biomass in the form of tree bark, namely acacia mangium. The aim of this study is to find out whether the process running in the Power boiler is good or not, it can be seen from its efficiency, so that the energy balance calculation is carried out on the Power boiler itself. Therefore, a study is needed to determine the energy balance of the unit. From the heat balance calculation, the heat data for producing steam was 1924,927,054 kcal, the latent heat of vaporization was 5732,620,038 kcal and the feed water heat was 11156296.65 kcal. So from the calculations obtained we can find out the energy balance in the boiler and the resulting Supply Steam Consumption

Abstract

The application of technology in the livestock sector has been carried out to increase the productivity of the livestock business. Closed chicken coops are one of the applications of technology in the livestock sector by utilizing a microcontroller that can control the temperature and ammonia levels in the coop under optimal conditions for fattening chickens. When the temperature rises (hot), the system set on the microcontroller will make the fan turn on automatically. This study aims to improve the offline and semi-manual fan control system in closed chicken coops to become automatic. By utilizing Internet of Things (IoT)-based technology, monitoring the condition of the chicken coop can be more easily accessed remotely. The method uses the if-then rule to regulate fan performance based on variable temperature and ammonia levels. The fan work set-point value can be set through the Android application online. Based on the test results, the IoT system treatment can work well. A consumer satisfaction survey was conducted on breeders with satisfactory results to ensure their feasibility as a commercial product.
