Abstract

Energi alternatif dari sinar matahari memiliki potensi besar dalam memenuhi kebutuhan energi di era modern saat ini. Salah satu teknologi yang memanfaatkan energi matahari adalah panel surya (solar cell) yang berfungsi mengubah energi matahari menjadi energi listrik. Namun, kebanyakan panel surya yang digunakan masih bersifat statis, hanya menghadap ke satu arah sehingga penyerapan energi hanya optimal pada waktu tertentu saja, terutama saat posisi matahari tepat di depan panel. Pada penelitian ini dilakukan perancangan dan pembangunan sistem solar tracker otomatis dengan menggunakan mikrokontroler Arduino Nano ATmega328 dan modul RTC (Real Time Clock) sebagai input waktu. Panel surya dirancang agar dapat bergerak secara dinamis mengikuti posisi matahari dari pagi hingga sore hari secara real-time. Sistem ini bertujuan untuk meningkatkan efisiensi penyerapan energi matahari sepanjang hari. Dengan menggunakan metode perancangan berbasis waktu (time-based tracking), sistem ini mampu mempertahankan posisi panel surya agar selalu tegak lurus terhadap arah datangnya sinar matahari. Hasil yang diharapkan dari penelitian ini adalah peningkatan daya output yang dihasilkan panel serta efisiensi sistem secara keseluruhan dalam pemanfaatan energi matahari sebagai sumber energi terbarukan. Alternative energy from sunlight has great potential in meeting energy needs in today's modern era. One technology that utilizes solar energy is solar panels (solar cells) which function to convert solar energy into electrical energy. However, most solar panels used are still static, only facing one direction so that energy absorption is only optimal at certain times, especially when the sun is directly in front of the panel. In this study, the design and construction of an automatic solar tracker system was carried out using an Arduino Nano ATmega328 microcontroller and an RTC (Real Time Clock) module as a time input. The solar panels are designed to move dynamically following the position of the sun from morning to evening in real-time. This system aims to increase the efficiency of solar energy absorption throughout the day. By using a time-based tracking design method, this system is able to maintain the position of the solar panels so that they are always perpendicular to the direction of the incoming sunlight. The expected results of this study are an increase in the output power produced by the panels and the overall system efficiency in utilizing solar energy as a renewable energy source.

Abstract

Algoritma nonlinier yang tersedia dalam literatur dan pengembangan yang dilakukan oleh para ilmuwan umumnya hanya dapat menentukan satu akar persamaan nonlinier dalam satu proses perhitungan. Pengembangan metode Bagi Dua dan metode Brent dapat menentukan beberapa akar persamaan polinomial. Dengan menerapkan prinsip metode Monte Carlo pada metode Bagi Dua dan Regula Falsi, ditemukan bahwa beberapa akar persamaan nonlinier dalam bentuk polinomial atau kombinasi persamaan polinomial dan eksponensial dapat ditentukan secara akurat dalam satu proses perhitungan.   Nonlinear algorithms available in literature and developments carried out by scientists generally can only determine a single root of a nonlinear equation in a single calculation process. The development of the Bisection method and the Brent method can determine multiple roots of polynomial equations. By applying the Monte Carlo method principle to the Bisection and Regula Falsi methods, it is found that multiple roots of a nonlinear equation in polynomial form or a combination of polynomial and exponential equations can be accurately determined in a single calculation process.

Abstract

Fenomena saturasi pada trafo arus memiliki dampak krusial terhadap kinerja rele proteksi dalam sistem tenaga listrik. Pengujian eksperimental dilakukan untuk menganalisis karakteristik trafo arus, dengan fokus pada hubungan antara arus masukan primer (I1​), arus keluaran sekunder (I2​), dan tegangan keluaran (V). Hasil menunjukkan korelasi positif antara I1​ dengan I2​ dan V. nilai V tetap konstan pada 5,5 Volt meskipun I1​ meningkat dari 600 mA ke 800 mA, dan nilai I yang kembali ke 1,3 A pada tegangan tertentu dalam pengujian terpisah. potensi saturasi inti trafo atau perilaku non-linear komponen yang diuji, yang berpotensi memengaruhi akurasi pengukuran arus oleh rele proteksi. khususnya saat mendekati atau memasuki kondisi saturasi. Perilaku non-linear, seperti yang ditunjukkan oleh nilai V yang stabil pada dua titik I1​ yang berbeda, dan penurunan I pada tegangan yang meningkat, pengujian karakteristik trafo arus secara menyeluruh untuk memastikan rele proteksi dapat beroperasi secara akurat dan tepat waktu, terutama dalam menghadapi kondisi gangguan yang mungkin menyebabkan saturasi trafo.   The saturation phenomenon in current transformers has a crucial impact on the performance of protection relays in electric power systems. Experimental testing was conducted to analyze the characteristics of current transformers, focusing on the relationship between primary input current (I1), secondary output current (I2), and output voltage (V). The results showed a positive correlation between I1 and I2 and V. The V value remained constant at 5.5 Volts even though I1 increased from 600 mA to 800 mA, and the I value returned to 1.3 A at a certain voltage in a separate test. potential saturation of the transformer core or non-linear behavior of the components under test, which could potentially affect the accuracy of current measurement by the protection relay. especially when approaching or entering saturation conditions. Non-linear behavior, as indicated by stable V values at two different points of I1, and a decrease in I at increasing voltage, thorough testing of the current transformer characteristics to ensure the protection relay can operate accurately and timely, especially in the face of fault conditions that might cause transformer saturation.

Abstract

Penelitian ini bertujuan untuk menganalisis faktor penyebab dan dampak dari tersumbatnya nozzle burner pada auxiliary steam boiler di kapal MV. Pan Kristine. Permasalahan yang muncul berupa penurunan tekanan uap dan flame failure saat kapal berlabuh, yang diduga disebabkan oleh gangguan pada sistem pembakaran. Data dikumpulkan melalui observasi langsung, wawancara dengan kru mesin, dokumentasi, serta studi pustaka. Hasil penelitian menunjukkan bahwa penyumbatan nozzle burner disebabkan oleh kurangnya perawatan rutin sesuai Planned Maintenance System (PMS), sistem filtrasi bahan bakar yang tidak efisien, nozzle yang aus atau rusak, serta jarak elektroda yang tidak sesuai dengan manual book. Dampak dari kondisi ini meliputi penurunan efisiensi pembakaran, peningkatan akumulasi jelaga dan kerak di ruang bakar, serta gangguan operasi boiler secara keseluruhan. Penelitian ini merekomendasikan penerapan PMS yang ketat, pemeriksaan berkala pada filter dan nozzle, serta pelatihan kru untuk meningkatkan pemahaman terhadap sistem pembakaran guna menjamin keandalan dan efisiensi kerja auxiliary boiler.   This study aims to analyze the causes and impacts of nozzle burner clogging in the auxiliary steam boiler aboard the MV. Pan Kristine. The issue arose from steam pressure drops and repeated flame failures while the ship was anchored, suspected to result from malfunction in the combustion system. Data were collected through direct observation, interviews with engine crew, documentation, and literature study. The findings reveal that the clogging of the nozzle burner is caused by insufficient routine maintenance according to the Planned Maintenance System (PMS), inefficient fuel filtration, worn or damaged nozzles, and electrode spacing that does not comply with the instruction manual. These issues lead to reduced combustion efficiency, increased soot and scale accumulation in the combustion chamber, and overall operational disruption of the boiler. The study recommends implementing a strict PMS, regular inspection of fuel filters and nozzles, and improved crew training to ensure the reliability and efficiency of the auxiliary boiler system.
