Abstract

Solar energy can be converted to electrical energy directly using photovoltaic (PV) modules. The output of electrical energy from the PV module is affected by the intensity of solar radiation and temperature. This study aims to monitor the output power of a solar power plant against changes in solar irradiation and temperature based on the Internet of Things (IoT). Off-grid solar power plants consist of PV modules, solar charge controllers, and batteries. The variables measured are output power, irradiation, module temperature, environment temperature, battery charge and discharge current, and voltage of system. All measurement results are sent via the internet to the ThingSpeak web server to be stored and displayed on a computer or android device connected to the internet. This monitoring system can monitor the real-time conditions of off-grid solar power plants. Monitoring results on 25 October 2022 showed the highest energy was 128 Watt hours with an efficiency of 16.06%.

Abstract

Electrical Vehicle (EV) has been developing since the mid-18th century and reached its peak at the end of the 18th century. Dwindling fuel reserves and environmental damage caused by exhaust emissions from millions of fossil-fuel vehicles are the driving factors for the development of electric cars, technological developments in the battery sector have also contributed to the development of electric cars. One of the important components in an electric car is the battery which will provide resources to the system, so determining the capacity and knowing the performance of the battery used is very important. To find out the battery performance, the model can be made using MATLAB/SIMULINK. The model built consists of electric (DC motor, control and battery) and mechanical (transmission, wheels, brakes and body) parts. Of the models made for speeds of 35, 40, and 45 kmph on level ground, the distances that can be covered are 2,292, 2,597, and 2,899 m, while the remaining battery capacity (SoC, %) is 92.93%, 91.16%, and 89.17%. This is proportional to the distance traveled which also proves that the model made is appropriate. Uphill roads affect the use of battery capacity, the greater the angle of incline, the greater the battery capacity used.

Abstract

In Durian Tibarau, West Pasaman, there are 6 Micro Hydro Power Plants (MHPP) with a total installed capacity of 234.5 kVA or 187.6 kW, 3 Phase, 400 V, 50 Hz. The 6 MHPP are adjacent to each operating location. For this reason, it is necessary to analyze the interconnection load flow of the MHPP system, to see the initial conditions of the voltage state, load flow and power losses. The formulation of the load flow equation is based on the power system of 6 MHPP buses, 6 load buses and 12 line, 400 Volt voltage. Completion of load flow analysis using the Adaptive Newton Raphson method with an iteration process and application of the Electrical Transient Analysis Program (ETAP) 12.6. The results of the load flow research show that the bus that is close to the generator is at nominal voltage while the bus that is far from the generator has a voltage drop. The biggest line power losses occur in the difference in bus voltage values ​​from the sending side bus to the receiving side bus. The total power generated by MHPP is equal to the total consumer load plus the total line power losses. Abstrak Di Durian Tibarau, Pasaman Barat ada 6 unit Pembangkit Listrik Tenaga Mikro Hidro (PLTMH) dengan total kapasitas terpasang 234,5 kVA atau 187,6 kW, 3 Phasa 400 V 50 Hz. Ke 6 unit PLTMH tersebut berdekatan letaknya beroperasi masing-masing. Untuk itu perlu dilakukan analisa aliran beban interkoneksi sistem PLTMH, untuk melihat kondisi awal keadaan tegangan, aliran beban dan rugi-rugi daya. Rumusan persamaan aliran beban berdasarkan sistem tenaga 6 bus PLTMH, 6 bus beban dan 12 saluran tegangan 400 Volt. Penyelesaian analisa aliran beban menggunakan metoda Adaptive Newton Raphson dengan proses iterasi dan aplikasi Electrical Transien Analisys Program (ETAP) 12.6. Hasil penelitian aliran beban menunjukan bahwa bus yang dekat dengan pembangkit berada pada tegangan nominal sedangkan bus yang jauh dari pembangkit turun tegangannya. Hasil rugi-rugi beban saluran terbesar terjadi pada perbedaan nilai tegangan bus dari bus sisi kirim ke bus sisi terima. Total daya dibangkitkan PLTMH sama dengan total beban konsumen ditambah dengan total rugi-rugi daya saluran.

Abstract

Terdapat permasalahan yang sering dialami oleh petani ketika menjelang panen padi yaitu adanya hama burung. Burung biasanya memakan biji-biji padi yang menyebabkan hasil panen berkurang. Umumnya petani menggunakan cara tradisional untuk mengusir hama tersebut yaitu dengan membentangkan benang atau membuat kentongan dari kaleng bekas. Cara tradisional tersebut kurang efektif dikarenakan jangkauan suara yang dihasilkan terbatas, juga membutuhkan waktu dan tenaga para petani. Alat pengusir hama padi ini adalah alat yang menimbulkan gelombang ultrasonic dengan frekuensi 2,5 – 60 kHz yang dapat diatur sesuai dengan frekuensi pendengaran burung pemakan padi. Selain itu juga dapat membangkitkan suara burung elang yang merupakan predator alami bagi burung. Catu daya diperoleh dari energi panas matahari melalui panel surya. Aktivitas kendali alat dilakukan secara otomatis berbasis microcontroller ATMEGA 328P dan Integrated Circuit Real Time Clock sehingga pengguna dapat menentukan rentang waktu penggunaan alat. Alat pengusir padi ini telah diuji di area persawahan masyarakat di Desa Pernek Kecamatan Moyo Hulu, Sumbawa.

Abstract

The application of artificial behavior in the object character of a game that is played using a computer device continues to grow. The implementation of the algorithm in the game makes game object characters that can move autonomously according to changes in scenario roles making the game more attractive to human players. This autonomous computer player behavior is known as a non-player character (NPC). In this research a game has been developed in the category of role-playing game (RPG) which is called the Fire Extinguisher Game. In this game there is an NPC character "fire monster" as an antagonist whose mission is to defeat the human player as the protagonist by burning all the objects in the scene role scenario. In order to make it clear and to make it easier to develop NPC player behavior designs, the Finite State Machine (FSM) method and godot script programming are used. The FSM method describes the behavior design of each NPC character in the form of states, where these will change according to the interactions that occur between players in the scene of the game environment. In its implementation, there are test parameters that are used, so that it can be shown that this game has successfully played. This game runs on a desktop and has tested using the black-box testing method to get a functional performance test. The results of this research are the design of artificial behavioral events on NPCs using the godot script code approach.

Abstract

Indonesia memiliki potensi energy surya yang sangat besar karena wilayhnya terletak di daerah katulistiwa. Energi surya dikonversi menjadi energi listrik melalui panel surya atau fotovoltaik (PV). Energi listrik yang dihasilkan oleh PV dapat langsung dipergunakan untuk mencatu beban atau disimpan dalam sebuah baterai. Penelitian ini menyelidiki disain sistem pengisian baterai dengan kendali Artificial Neural Networks (ANN). Sistem pengisian baterai dimodelkan menggunakan Matlab / Simulink. ANN dilatih dengan menggunakan data masukan dan keluaran yang didapat dari sistem pengisian baterai yang dikontrol dengan PI. ANN dilatuh dengan algoritma backpropagation. Hasil penelitian menunjukkan bahwa Buck-Boost Converter mmpu mempertahankan tegangan pengisian baterai yang relatif konstan yakni diantara 12.93 V - 14.01 V, pada tegangan keluaran PV yang bernilai diantara 14,01 V - 15,72 V. Sedangkan respon performansi sistem yang dihasilkan dengan kendali PI dan ANN sama yaitu nilai overshoot terbesar senilai 4.99% dan nilai settling time maksimum sebesar 7.16 s. Unjuk kerja performansi respon dari sistem yg dikontrol dengan PI dan ANN cedrung sama. Hal ini disebabkan oleh proses training ANN yang belum optimal karena data latih yang digunakan masih terbatas.
