Abstract

Bencana alam sering kali mengakibatkan gangguan pada sarana dan prasarana umum serta kesulitan dalam kegiatan pencarian dan perbaikan. Dalam kondisi seperti ini, catu daya portabel yang menggunakan baterai menjadi solusi yang berguna untuk menyediakan sumber energi cadangan. Namun, penggunaan baterai pada catu daya portabel juga memunculkan kekhawatiran terkait estimasi penggunaan daya yang tersedia. Oleh karena itu, penelitian ini bertujuan untuk mengembangkan sistem pemutus catu daya dan algoritma estimasi lama penggunaan baterai untuk memastikan penggunaan daya yang optimal dan mencegah kehabisan daya secara tiba-tiba. Dalam penelitian ini, dilakukan pengujian terhadap perangkat yang mampu mengukur tegangan dan arus baterai dengan tingkat akurasi yang tinggi. Hasil pengujian menunjukkan bahwa perangkat memiliki akurasi pengukuran tegangan sebesar 99,02% dibandingkan dengan pengukuran menggunakan voltmeter. Selain itu, perangkat juga mampu mengukur nilai keluaran dari sensor arus dengan akurasi sebesar 94,2%. Sistem pemutus catu daya pada catu daya portabel telah berhasil dikembangkan untuk mengatasi penggunaan daya yang melebihi toleransi sistem. Jika daya yang digunakan melebihi 350 Watt, sistem akan memberikan tanda peringatan dan dalam jangka waktu tertentu, jika beban tidak dikurangi, sistem akan otomatis memutuskan penggunaan beban tersebut. Sistem ini juga mampu membatasi penggunaan energi pada baterai agar tidak melebihi nilai minimum yang diperbolehkan. Selain itu, estimasi penggunaan baterai juga dapat dihitung berdasarkan jumlah beban yang terhubung dengan tingkat akurasi sebesar 95,58%. Penelitian ini memberikan kontribusi penting dalam pengembangan catu daya portabel untuk situasi bencana alam. Dengan adanya sistem pemutus catu daya dan estimasi penggunaan baterai yang akurat, pengguna dapat mengoptimalkan penggunaan daya dan menghindari kehabisan daya yang tidak terduga. Hal ini akan meningkatkan efektivitas dalam upaya pertolongan pertama, khususnya dalam hal penerangan dan komunikasi, serta memberikan dampak positif terhadap psikologis para korban bencana. Kata kunci: catu daya portabel, baterai, pemutus daya, estimasi baterai, low voltage discharger

Abstract

Poultry farming, especially laying hens, is a promising subsector of agribusiness that plays a vital role in improving the welfare of farmers and national development. The development of this poultry farming aims to increase livestock production to meet the needs of food, nutrition, and farmer income. In Indonesia, East Java is the largest producer of chicken eggs due to high consumption demand and the high nutritional content of eggs from laying hens. However, poultry productivity is influenced by various factors, such as breed, feed, nutrition, health, and cage conditions. Manual monitoring of the conditions of broiler chicken cages is considered inefficient, leading to the need for research to create an efficient and flexible broiler chicken cage monitoring system. The monitoring system employs sensors for temperature, light intensity, water level, and weight, capable of monitoring cage conditions in real-time through an Android smartphone using the Blynk platform. The test results show that each sensor exhibits high accuracy: temperature sensor 99.46%, light intensity sensor 99.37%, weight sensor 99.07%, and water level sensor 99.79%. Additionally, data transmission and notifications on Blynk were successful without any discrepancies, allowing data sent by the ESP32 to be accurately and promptly displayed on the LCD and Blynk when connected to the internet. Keywords: Temperature, Light Intensity, Food Weight, Water Level, Blynk

Abstract

Renewable energy is an alternative energy as a substitute for fossil fuels, one of which is solar energy. The problems with photovoltaic technology are low energy conversion efficiency and inconsistent solar radiation. So that from these problems it is necessary to optimize the output power of solar panels using Maximum Power Point Tracking (MPPT) which works by tracking the maximum power point that can be generated by the solar panel system and keeping it always working at that point. In this study, this MPPT Solar Charge Controller uses a Buck-Boost Converter, as well as Incremental Conductance and Hill Climbing as control methods. Both of these methods will be analyzed by comparing the increase in output power through MATLAB Simulink software simulation. Based on the results obtained from the simulations and calculations using the two MPPT methods, it was found that there was an increase in the output power of the solar panel system by 31.17W or 56.9% for the Incremental Conductance method and 7.23W or 13.2% for the Hill Climbing method, compared to PV systems without using MPPT.

Abstract

In floating cage cultivation, security is one of the important aspects to be considered. Possible threats include fish theft, theft of cultivation equipment, predator attacks such as birds or predatory fish. The importance of security devices against fish thieves in floating cages on Gili Ketapang Island cannot be underestimated. In an effort to protect and maintain the sustainability of fish farming, the use of effective security devices is essential. By installing security devices such as suspected movement detection, notification delivery, and sirens, cage owners can increase the likelihood of detection and prevent acts of fish theft. These devices provide better surveillance and allow cage owners to respond quickly in case of suspicious behavior. To prevent fish theft in floating cages, research was conducted to design a cage security system. An effective security system can help identify and prevent theft or attacks on floating cages, improve supervision, and provide a sense of security to cage owners. In this final research project, we will analyze the performance of ESP32 Cam in sending images, analyze the performance of SIM800l module in making calls and power consumption in the security system of fish theft in floating cages. The implementation results obtained that the security system using a 17Ah LifePO4 battery was able to be active for 12 hours in standby conditions with a total power of 2.88W and in a state of detecting movement the system was able to be active for 2.5 hours with a total power of 35.96W. In this study, a security system was designed for monitoring cages remotely using ESP32 Cam using telegram bot assistance, for motion detection using the SIM800l module with PIR sensor as object detector and triggering the SIM800l module to make a call. The results of this study are that for monitoring, ten tests were carried out and had a success percentage of 90%, for motion detection it had a success rate of 80% by conducting ten tests.

Abstract

This research discusses the Proportional-Integral-Resonant (PIR) control system used to regulate a three-phase induction motor, ensuring stability of the speed output and reducing ripple in the DC current output. The study also covers the modulation techniques employed to control the switching of the rectifier using the Space Vector Pulse-Width Modulation (SVPWM) method, where the threephase current and voltage are represented in synchronous rotating coordinates. In this control strategy, a vector control with SVPWM modulation technique is utilized to achieve optimal DC voltage output. To obtain an optimal controller design, parameter gain tuning is performed on the speed, flux, and torque control cascade using the symmetrical optimum method. Simulation testing is carried out using MATLAB/Simulink software to demonstrate the stability of the speed output and the DC current output of the three-phase induction motor. The three-phase induction motor with the PIR controller yields better results compared to the PI controller, achieving a speed of 163.2 rad/s, reaching a steadystate condition within 0.317 seconds, exhibiting overshoot, and a steady-state error of 2.39%. Keywords: Three phase induction motor, PIR controller, Direct Torque Control, symmetrical optimum.
