CCTV pada umumnya dihidupkan secara terus menerus dalam kurun waktu yang ditentukan pengguna. Penggunaan CCTV secara terus menerus berdampak pada pemborosan daya listrik dan usia penggunaan perangkat lebih singkat. Maka diperlukan penelitian CCTV hemat energy dan hidup hanya pada waktu yang diperlukan untuk penggunaan perangkat CCTV yang lebih lama. Tujuan penelitian ini adalah membangun Closed Circuit Television (CCTV) yang hemat energi dan masa penggunaan perangkat yang lama. Terdiri dari dua blok uatama yaitu CCTV Sistem dan blok controller. Blok CCTV berfungsi menangkap gambar dan menampilkan pada layar LCD 14 Inchi. Blok controller dengan pemroses Utama NodeMCU ESP32 sebagai pengatur waktu CCTV mendapat tegangan listrik untuk hidup. CCTV Cerdas ini akan bekerja pada rentan waktu jam 21.00 malam sampai 06.00 pagi dengan mengimplementasikan modul Real Time Clock (RTC) untuk masukkan waktu. CCTV Cerdas mendapat tegangan supply jika sensor PIR Motion mendeteksi panas tubuh manusia pada radius 3 Meter.  Berdasarkan hasil pengujian alat dapat disimpulkan bahwa CCTV Cerdas berbasis NodeMCU ESP-32 dapat bekerja dengan baik yaitu setiap kali sensor PIR mendeteksi panas tubuh maka akan menyalakan unit CCTV.Closed circuit television abbreviated (CCTV) has been widely used by companies and households for monitoring. CCTV users generally turn it on continuously. Continuous use of CCTV has an impact on wasting electrical power and shortening the device's lifespan. research was carried out on energy-saving CCTV and a longer CCTV usage period. The aim of this research is to build a Closed Circuit Television (CCTV) that is energy efficient and has a longer device usage period. Smart CCTV Consists of a CCTV System block and a controller block. The CCTV block functions to capture images and display them on a 14 inch LCD screen. The controller block with the NodeMCU ESP32 main processor as the CCTV timer gets electrical voltage to turn on. This Smart CCTV will work between 21.00 pm to 06.00 am by implementing a Real Time Clock (RTC) module to enter the time. The CCTV block gets a supply voltage if the PIR Motion sensor detects human body heat in a radius of 3 meters. The test results show that the NodeMCU ESP-32 based Smart CCTV can work well. The CCTV block will always turn on whenever the PIR sensor detects human body heat.","PeriodicalId":292481,"journal":{"name":"Jambura Journal of Electrical and Electronics Engineering","volume":"59 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140505808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thing that is most needed in a solar power plant is the intensity of solar radiation. Based on this, Indonesia is very suitable for implementing solar power plants. The power produced by a solar power plant is directly pro-portional to the intensity of solar radiation received by the solar panels. To maximize electrical power production, it is necessary to design a series of solar panel units to be connected in series or parallel. Solar panels connected in parallel will increase the nominal total voltage, whereas when connected in series they will increase the nominal total current. This research discusses the effect of the series-parallel configuration of solar panel installation on the power production received in a building in the campus environment. The method used to obtain the most optimal energy production is to use a combination of series and parallel solar panels. Daily sunlight data is simulated via PvSyst. The research results show that the most optimal energy production is obtained by designing a series circuit of 20 panels combined with a parallel circuit of 5 panels. The more modules connected in series, the total voltage will increase. The more modules that are connected in parallel, the total current will increase. ","PeriodicalId":292481,"journal":{"name":"Jambura Journal of Electrical and Electronics Engineering","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140506446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nah ini merupakan menjadi tantangan tersendiri bagi supir mobil terlebih mobil yang besar tentunya memiliki blind-spot atau titik buta yang lebih tinggi. Kadang setiap orang yang ingin memakirkan kendaraan tersebut harus menengok ke kaca spion walaupun,memiliki kaca spion tetap saja kita tidak bisa mengetahui jarak yang pasti antara objek dibelakang dan mobil dan kadang kita pun berbalik ke belakang untuk mengetahui apakah ada objek di belakang atau tidak tentu ini dapat menjadi masalah yang cukup serius dikarenakan dapa membahayakan orang di sekitar ataupun merugikan kita sendiri jika terjadi tabrakan yang mana terjadi dikarenakan blind-spot. Dalam masalah tersebut kami membuat prototipe, “Rancang Bangun Sistem Sensor Parkir Kendaraan Roda Empat Berbasis Mikrokontroler” Sistem Sensor Parkir ini merupakan sistem yang digunakan untuk mendeteksi objek di belakang dengan memanfaatkan sensor HC-SR04, dengan pengaturan jarak yang bisa diatur. Bila sensor mendeteksi ada benda di belakang kendaraan ada lampu indikator (Led) yang menyala dan alarm / buzzer yang ada berbunyi, kemudian dari bunyi peringatan ini pengemudi dapat mengetahui dan sadar bahwa kendaraannya dekat dan hampir menabrak objek yang ada di belakangnya dengan adanya sensor parkir ini dapat meminimalisir terjadi tabrakan bagi orang, objek, dan lain-lain. Metode yang digunakan yaitu prototipe pengembangan. Hasil pengujian sistem menunjukkan bahwa sistem sensor parkir ini berfungsi dan memiliki akurasi yang baik dalam mendeteksi objek dan meningkatkan efisiensi pengendara dalam memarkirkan mobilnya.Parking is an activity that we frequently engage in and is mandatory for those of us who own vehicles, especially four-wheeled ones. Precision is required when parking, particularly to avoid collisions. This becomes a significant challenge, especially for drivers of larger vehicles that may have higher blind spots. Often, individuals who wish to park their vehicles must check their rearview mirrors. However, even with rearview mirrors, it's challenging to ascertain the precise distance between objects behind the vehicle. At times, we need to turn around to determine whether there are objects behind us, which can be a serious issue as it may endanger people in the vicinity or result in accidents due to blind spots.To address this issue, we have developed a prototype titled \"Design and Construction of a Four-Wheeled Vehicle Parking Sensor Sistem Based on Microcontroller.\" The Parking Sensor Sistem is designed to detect objects behind the vehicle using an HC-SR04 sensor with adjustable distance settings. When the sensor detects an object behind the vehicle, indicator lights (LEDs) illuminate, and an alarm/buzzer sounds.

Dalam menunjang operasional, Bandara SAMS Sepinggan tidak hanya mengandalkan sumber daya listrik primer dari PLN saja, ketika sumber PLN mengalami pemadaman maka sumber daya listrik sekunder berperan yaitu genset dan Uninterruptible Power Supply (UPS) sebagai catu daya cadangan tidak terputus khususnya pada beban AFL. Suplai daya listrik sekunder pada Bandara SAMS harus dapat membangkitkan daya sebesar 94.33 KVA untuk beban AFL. Metode load flow analysis digunakan untuk Analisa sistem back-up daya menggunakan program ETAP (Electric Transient Analysis Program) dengan tiga skenario. Setiap skenario disesuaikan dengan kondisi yang dimungkinkan terjadi ketika terjadi pemadaman. Skenario paling kritis yaitu skenario menggunakan suplai dari UPS dimana genset belum siap karena satu atau lain hal. Genset dapat membangkitkan daya sebesar 84.2 KW untuk mengisi daya UPS dan melayani beban sebesar 94.33 KVA.

Untuk meminimalisir hal tersebut dapat dilakukan pemasangan kapasitor bank secara paralel. Tujuan penelitian ini adalah menganalisis pengaruh kapasitor bank terhadap nilai faktor daya dan nilai jatuh tegangan dengan metode perhitungan segitiga daya yang disimulasikan dengan software Etap 19.
