Abstract

Half-wave rectifier, full-wave rectifier, inverting op-amp amplifier, and non-inverting op-amp amplifier are basic electronic practicum material in each Electrical Engineering Department. During this practicum is carried out by arranging the circuit manually using breaadboard, so it requires a long time and is inefficient. In this study a trainer with integrated modules was designed. The module consists of a wave rectifier module, transistor amplifier module, op-amp amplifier module, and logic gate. This trainer is designed based on the ATmega 32 microcontroller which functions to select modules, display module workmanship, and basic logic gate programs. The method used in this research is experiment and simulation. From the test results, the half-wave rectifier and full-wave rectifier modules respond according to the simulation of ideal conditions. While the results of testing the inverting amplifier and non-inverting amplifier, show both modules can function in accordance with theory and simulation. So it can be concluded that this trainer can be used for practical learning.

Abstract

Due to the busy activities outside the home, some people do not have time or forget to water their plants, so when they return home they find that the plants have died from drought. Therefore, to overcome this problem by conducting research using Internet of Things technology. The aim of this research is to design an automatic watering tool to overcome manual watering and support learning. This prototype uses a NodeMCU ESP8266 as the main controller, a soil moisture sensor is used to read soil moisture.  Soil moisture sensors are used to detect soil moisture. If the soil humidity is below the minimum limit, the watering process will be active and the watering process will be active if the NodeMCU ESP8266 receives commands from the smartphone.

Abstract

Pencabutan subsidi tarif listrik telah mengakibatkan peningkatan beban biaya listrik bagi masyarakat. Penelitian ini bertujuan merancang dan menganalisis performa sistem pembangkit listrik tenaga surya (PLTS) on-grid tanpa baterai untuk aplikasi rumah tangga. Metode penelitian mencakup perancangan sistem dengan 8 panel surya polikristalin 270 WP, inverter 5 kW, dan KWH meter ekspor-impor. Hasil pengujian selama 6 bulan (Maret-Agustus 2023) menunjukkan bahwa sistem mampu menghasilkan total energi sebesar 4030 kWh dengan rata-rata produksi harian 18-22 kWh pada kondisi optimal. Faktor eksternal seperti intensitas cahaya matahari dan kondisi cuaca berpengaruh signifikan terhadap efisiensi sistem, dengan penurunan produksi energi hingga 40-50% pada musim hujan. Total energi yang diekspor ke jaringan PLN mencapai 1338 kWh, yang menghasilkan penghematan biaya sebesar Rp 1.478.081 berdasarkan kebijakan kompensasi 65% dari nilai ekspor. Hasil perbandingan dengan studi terdahulu menunjukkan bahwa sistem tanpa baterai ini memiliki keunggulan dalam efisiensi biaya awal hingga 40% meskipun memiliki keterbatasan dalam kontinuitas pasokan daya. Simpulan penelitian mengindikasikan bahwa PLTS on-grid tanpa baterai merupakan solusi ekonomis untuk mengurangi ketergantungan pada jaringan listrik konvensional, dengan payback period 5-7 tahun. Penelitian ini merekomendasikan optimasi sistem melalui penyesuaian orientasi panel dan pertimbangan kebijakan tarif ekspor yang lebih menguntungkan.
