Abstract

Abstrak – Pemanfaatan energi listrik sebagai upaya menciptakan green energy memerlukan suatu tindakan yang mendukung produksi energi yang efisien dengan menggunakan satu atau lebih energi alternatif yang dapat digabungkan menjadi sumber energi terdistribusi. Permasalahan pokok permintaan sumber energi yang semakin meningkat adalah keandalan sistem dan kualitas daya. Kualitas daya berkaitan dengan pengurangan nilai rugi-rugi daya listrik, berkurangnya nilai jatuh tegangan serta kontinuitas penyaluran energi listrik yang baik. Penambahan distributed generation (DG) pada sistem eksisting dinilai mampu mengurangi permasalahan kualitas daya dan meningkatkan keandalan sistem. Penelitian ini membahas optimasi penempatan DG dengan menggunakan metode Cat Swarm Optimization dan Krill Herd Algorithm. Optimasi dilakukan dengan menginjeksi DG pada sistem eksisting. Dari proses optimasi dengan CSO diperoleh penurunan rugi daya sebesar 0,2 % sedangkan dengan KHA diperoleh penurunan 29,5 %. Perbaikan profil tegangan dengan metode KHA dinilai lebih baik dari CSO dengan nilai diatas 0,99 p.u sedangkan CSO 0,96 p.u. Penelitian ini mengindikasikan bahwa metode KHA lebih baik daripada metode CSO.Kata Kunci — Distributed Generation, Cat Swarm Optimization, Krill Herd Algorithm.

Abstract

Pembangkit listrik tenaga surya pada umumnya tidak dapat bekerja pada daya maksimum dengan sendirinnya, karakteristik tegangan PV pada umumnya mengikuti tegangan batarai atau beban yang terhubung langsung ke PV. Intensitas cahaya yang diterima oleh modul-modul PV pasti tidak semuanya mendapatkan iradiasi yang seragam, sehingga daya yang dihasilkan tidak optimal dan menimbulkan multi-peak. Untuk mengoptimalkan daya dari PV diperlukan sistem Maximum Power Point Tracking (MPPT). Namun metode yang sering digunakan masih sering terjebak dalam local peak dan waktu konvergen yang lama. jurnal ini membandingkan performa pelacakan dan waktu pelacakan menggunakan 2 metode, yaitu Ant Colony Optimization (ACO) dan Particle Swarm Optimization (PSO). Hasil percobaan menunjukkan algoritma ACO mempunyai efisiensi rata-rata keseluruhan yang lebih unggul 1,58% dari PSO, namun algoritma ACO lebih lambat dalam pelacakanya.

Abstract

Technological developments in the 4.0 era are currently growing rapidly, one of the advantages is that it makes it easier for users to control electronic equipment remotely. Only with a device, users can access all information through connectivity called the Internet of Think. The Internet of Things is a technological concept where all electronic equipment is interconnected with internet media so that it can be controlled or monitored from wherever the user needs it. The purpose of this research is to create a room condition control system based on the Internet of Think, where the device can be operated either automatically according to the schedule we set or manually. This system also has a monitoring system via a web server so that we can control and monitor the device without having to approach the device to turn it on or off. The device made in this study utilizes a temperature sensor and a smoke sensor as a sensor input medium to the controller. As an output, it utilizes a servo that is used to open and close the window so that the condition of the room can be controlled. To control the device remotely, the device is connected wirelessly by using wifi media which is one of the features of the nodemcu controller. The output of this research is the servo status on the window, fan, and air content displayed on the device and the web so that comfortable room conditions can be created according to the predetermined set point.

Abstract

The era of post-truth has caused many cases where politicians bring down their opponents in various ways to get pleasure. This pleasure is known as schadenfreude. This study aims to determine the description and factors that influence scadenfreude in politicians. The subjects in this study were regional-level politicians from one of the Z political parties in city X as many as three subjects. The research method used in this research is a qualitative research method with a phenomenological approach. The main data collection technique in this study used semi-structured interviews. The data analysis technique in this study used content analysis. Researchers used triangulation of data sources with significant persons to meet the data validity requirements. The findings show that there is schadenfreude in politicians. Schadenfreude's emotional appears to politicians because of competition and tend to favor their own party. Politicians expect their opponents to lose, so they are happy with their victory. The defeat received by an opponent with bad morals is deemed appropriate to feel happy if the opponent loses. This research is an illustration for politicians not to engage in behavior related to schadenfreude because it has a negative impact on the democratic process.
