Abstract

Permasalahan yang masih dihadapi petani sawit saat panen adalah harus memantau dari dekat buah sawit sebelum dipetik. Jika kebun sawitnya sangat luas maka harus dilakukan oleh beberapa orang dan memakan waktu lama. Untuk mengatasi masalah tersebut dapat dibuat sebuah sistem pemantauan berbasis IoT. Umumnya tingkat kematangan buah sawit dapat ditentukan dari warnanya. Dengan memasang sebuah sensor warna pada tiap pohon sawit dan sebuah kontroler untuk komunikasi jarak jauh maka petani atau pemilik kebun dapat memantaunya dari jauh setiap saat. Jika buah telah matang sistem akan mengirim pesan melalui chat Telegram. Untuk merealisasikan sistem dibutuhkan sebagai sebuah kontroler jaringan internet yaitu node MCU, sensor warna dan hotspot internet. Sensor membaca warna buah dari dekat dan mengubahnya menjadi data digital kemudian diproses oleh mikrokontroler node MCU. Mikrokontroler mengidentifikasi warna dan mengirim pesan sesuai kondisi buah.  Dengan sistem ini diharapkan dapat memudahkan pekerjaan petani saat memanen.

Abstract

Dalam semua bidang kehidupan dunia dewasa ini, semakin tergantung pada energi listrik, baik sebagai sumber penggerak mesin, alat penerangan, alat perhubungan, alat komunikasi dan sebagainya. Pertumbuhan yang semakin besar di bidang teknik elektro perlu dilayani oleh sumber daya manusia yang tangguh. Listrik yang berkualitas sangat diinginkan konsumen, agar konsumen merasa puas dengan pelayanan yang baik. Sistem tenaga listrik harus mampu menyediakan tenaga listrik bagi pelanggan dengan frekuensi yang konstan. Daya listrik yang keluar dari trafo daya kemudian di distribusikan kekonsumen merupakan daya aktif dan daya reaktif. Daya aktif ialah daya yang sebenarnya terpakai untuk melakukan usaha (daya nyata). Daya reaktif ialah jumlah daya yang diperlukan untuk pembentukan medan magnet. Contoh alat listrik yang mempengaruhi daya reaktif ialah transformator, motor listrik, lampu pijar, dan lain-lain. Frekuensi yang stabil merupakan salah satu jenis pelayanan yang harus dipenuhi suatu pembangkit, karena frekuensi yang tidak stabil dapat menyebabkan kerusakan pada peralatan elektronik. Jelas ini sangat merugikan konsumen rumah tangga dan perkantoran dan bagi dunia industri frekuensi yang tidak stabil dapat menyebabkan putaran motor listrik dapat berubah-ubah pastinya ini mengganggu proses produksi. Penyimpangan frekuensi dan nilai nominal harus selalu dalam batas-batas toleransi yang diizinkan.

Abstract

This study aims to design and build a Micro Hydro Power Plant (PLTMH) as an alternative solution for providing electrical energy in remote areas with adequate water flow potential. PLTMH utilizes kinetic energy from river flow to drive a turbine, which is converted into electrical energy through a generator. The research process involves several important stages: survey of water flow potential, design of mechanical and electrical systems, and installation and testing of the system. The survey aims to determine the optimal water discharge, while the design includes the selection of components such as turbines, generators, and electrical power control systems. The results of the study indicate that the designed PLTMH is capable of producing 1 kW of electrical power, sufficient to meet the basic needs of several households in remote areas. Further testing indicates that this system operates with high efficiency, stability, and minimal environmental impact, making it an environmentally friendly technology. Other advantages are the stability of the electricity supply produced and ease of maintenance and operation. This PLTMH is a sustainable solution for limited access to electrical energy in rural areas. Given its wide application potential, PLTMH can contribute to reducing dependence on conventional electricity networks and providing an affordable and reliable energy alternative for communities in hard-to-reach areas.

Abstract

This study discusses the analysis of transients that occur in capacitor bank switching using a power factor regulator (PFR). Electric power systems use capacitor banks to offset reactive power, enhance power factors, and minimize energy losses. However, the switching process in capacitor banks can cause significant voltage and current spikes, known as transient phenomena, which can damage equipment and disrupt system stability. This study conducts simulations and analyzes the impact of transients that occur during the capacitor bank switching process on the electric power system. The simulation is carried out using software that models the behavior of the electric power system, focusing on how the power factor regulator regulates the switching process and its impact on the resulting transients. The simulation results show that the use of PFR can reduce the negative impact of transients, but improper settings can still cause disturbances that have the potential to damage the system. These findings provide important insights for system engineers in designing and operating more reliable power systems, considering the importance of proper settings on the power factor regulator to minimize the effects of transients on capacitor bank switching. This study also recommends several mitigation strategies to reduce the impact of transients and improve overall system stability.
