Abstract

Pandemic people don't have free access to Gym. The importance of keeping the body fit. This can be overcome with the Human Pose Estimation Computer Vision technique. Optimum and maximum distance testing data. Webcam detects movement and test data on AI Fitness Counter models. Human Pose Estimation detection data is taken when someone does fitness exercises such as pull ups, pushups, and lifting weights. Optimal webcam detects Human Pose Estimation model AI Fitness Counter is three meters. Every detail of the landmarks in the pose corresponds to the key points of each limb and the utility lines that connect form the skeleton of the body. The application of the number of detection repetitions takes advantage of the angle of the elbow when it is straight and when it is bent. The angle forms 300 then a stage up occurs and is counted as one repetition. Meanwhile, when the angle forms 1700, a stage down occurs, and one repetition is counted as well. The use of Media pipe for the detection results is accurate and effective. This detection was successful because all members of the body were detected.

Abstract

This research focuses on the importance of maintaining generator output voltage stabilization using automatic voltage regulator (AVR), especially in dealing with load impacts and environmental changes. Through the implementation of internet of things (IoT), this system can be controlled and monitored remotely, enabling real-time monitoring without physical presence at the generator location. The main objective of this research is to increase energy efficiency by optimizing generator operation. System development methods include design, prototyping and testing stages. Test results show that the automatic voltage regulator is effective in maintaining a stable output voltage of around 220 V, even though the current varies according to the existing load. The power produced ranges from 23 to 670 W, with a power factor between 0.7 and 1. Despite a slight voltage drop to 217 V, the power factor increases to 0.93. The system uses NodeMCU to send data to Blynk and Google Spreadsheets servers, as well as servo motors and PZEM-004T sensors for control and monitoring. Overall, this research shows that the internet of things-based automatic voltage regulator system is effective in maintaining stability and increasing generator operational efficiency, with the ability to manage voltage, current, power, and power factor efficiently.

Abstract

At this time the cost of electricity is very expensive which is felt by the community because the government is still exploring oil and natural gas which is the need for non-renewable energy sources that are running low. This non-renewable energy still dominates for power generation in the thousands of Mega Watts. To anticipate the problem of non-renewable energy that is so big, you can use the On Grid-Tie System, sunlight is converted into DC voltage through the Solar Module, a pure DC voltage that comes out of the solar module. And Off Grid-Tie System namely sunlight is converted into DC voltage through the Solar Module, pure DC voltage generated from the solar module. Then the pure DC voltage uses a DC to DC regulation module or is called a DC regulator. DC regulator which aims to regulate the storage of DC current into the battery. Then the battery is used to supply power to the inverter. The method used in this study uses an off-grid solar home system as a power supply for households that are far from the electricity network or save electricity consumption due to expensive electricity rates. For settings for the intensity of sunlight using a portable holder, the solar panels are shifted manually in order to get the optimal light intensity to produce large output power. In off-grid application testing at household loads, from a load test of 93.5 watts to 750 watts, it shows that the load current is getting bigger and the discharging current is also large so that the duration of using the off-grid system from a load of 93.5 watts is 6 hours long and at a load of 750 watts. up to 15 minutes. This is because the condition of the lead-acid battery is maintained from 13.56 to 11.5 Volt DC, the battery should not be forced below the 11.5 Volt voltage because it will cause damage to the battery. For the use of loads that respond to very high instantaneous currents such as electric irons, dispensers, rice cookers should use more batteries and use an off-grid system voltage higher than 12 Volt DC.

Abstract

Sistem listrik yang disediakan oleh PT. PLN (Persero) memainkan peran krusial dalam memenuhi kebutuhan energi listrik di Indonesia. Dengan pertumbuhan pesat permintaan energi, terutama dalam sektor industri, komersial, dan rumah tangga, tekanan semakin besar pada jaringan distribusi listrik untuk menjaga keandalan pasokan daya. Salah satu tantangan utama adalah rugi-rugi daya dalam jaringan distribusi 20 kV, yang mengakibatkan kerugian finansial yang signifikan bagi PT. PLN (Persero) dan memengaruhi kualitas layanan kepada pelanggan. Penelitian ini mengusulkan penggunaan metode Binary Particle Swarm Optimization (BPSO) untuk merancang ulang konfigurasi jaringan distribusi 20 kV dengan tujuan mengurangi rugi-rugi daya. Rekonfigurasi jaringan dilakukan dengan mengubah status kabel penghubung antar trafo distribusi, tetapi mempertahankan struktur jaringan radial dan memperhatikan batasan operasi. Metode BPSO mengoptimalkan topologi jaringan dengan meminimalkan kehilangan daya nyata. Penelitian ini dilakukan di PT. PLN (Persero) ULP Krueng Geukueh dengan menggunakan simulasi software Electrical Transient Analizer Program (ETAP) versi 19.0.1 dan Matlab 2018b. Hasil penelitian menunjukkan bahwa rekonfigurasi berhasil mengurangi rugi daya nyata secara signifikan, dengan penurunan dari 19.732 menjadi 19.4 kW.

Abstract

Transformator distribusi merupakan salah satu komponen yang sangat penting dalam penyaluran tenaga listrik dari gardu distribusi ke pelanggan. Pelayanan terhadap pelanggan akan terganggu sehingga apabila terjadi pemutusan aliran listrik atau pemadaman yang diakibatkan dari kerusakan pada Transformator Distribusi. Transformator distribusi yang mengalami beban yang melabihi 80% dari kapasitas transformator tersebut maka akan berefek pada umur/life time transformator distribusi dan juga dapat mempengaruhi tingkat dan mutu pelayanan pada konsumen serta berpotensi besar terjadi gangguan. Maka dari itu perlu dilakukan suatu tindakan agar persentase pembebanan transformator distribusi tidak melebihi kapasitas trnasformator dengan metode pemasangan Trafo Sisip. Motode penelitian dalam skripsi ini menggunakan metode kuantitatif dan juga menggunakan simulasi software ETAP 12.6.0.  Di PT.PLN (Persero) ULP LANGSA KOTA terdapat transformator yang mengalami pembebanan berlebih (overload) yang terjadi pada Gardu Distribusi TC-7 sebesar 84,85% dan dilakukan pemasangan Trafo Sisip, pembebanan pada gardu TC-7 menjadi 49,65%. Dengan ini dapat dibuktikan bahwa pemasangan Trafo Sisip merupakan metode yang cukup baik untuk mengatasi gangguan pembebanan berlebih (Overload) pada Gardu TC-7, sehingga dapat memperpanjang umur trafo / life time transformator, menngkatkan kualitas pelayanan pada pelanggan dan mengurangi potensi terjadinya gangguan karena transformator pembebanan dibawah 80% dapat bekerja secara baik. Kata Kunci : Transformator, Trafo Sisip, Pembebanan berlebih (overload)
