Abstract

Tujuan penelitian ini adalah mendesain dan menguji hybrid panel surya type monocrystalline daya 60 Wh pada laju aliran fluida 0,027 kg/s. Dari hasil beberapa penelitian sebelumnya menunjukkan bahwa panel monocrystalline menyerap panas yang besar dibandingkan dengan yang jenis polycrystalline pada kondisi cuaca yang sama. Jika ini terjadi dalam jangka waktu yang lama, maka suhu permukaan panel akan semakin tinggi yang berimplikasi menurunnya efisiensi elektrik dan/atau konversi energi panas menjadi energi listrik akan berkurang. Oleh karena itu dibutuhkan media pendingin yang saling menguntungkan. Artinya dengan menhybrid dengan sirkulasi fluida (T) pada photovoltaic (PV) atau PVT, akan mempertahankan bahkan meningkatkan efisiensi elektrik PVT meskipun efisiensi thermal pada artikel ini masih perlu ditingkatkan. Disamping itu, arus yang dihasilkan lebih besar jika dengan PVT dibandingkan PV, sementara tegangan listrik cenderung tetap. Efisiensi elektrik maksimum PVT yang dihasilkan adalah sekitar 18,87% dengan suhu air panas sekitar 49oC, sementara yang PV adalah 10,89%. Ada peningkatan sekitar 8% yang menunjukkan hasil yang signifikan.

Abstract

This study aimed to see how the response changes in the speed DC motor and the armature current at the time of starting and stopping. The method used is a simulation using matlab software. By using the data specification n =ωDripproof type DC motors as well as testing the obtained value of ωn =55.44 rad / sec and ξ =0.3518. Because value ξ smaller than one, then the DC motor has a characteristic of less damped (underdamped).

In the future, ESDM have planned to add the capacity of PV system to supply the other AC. The objective of this study was to design PLTS system for supplying other AC and lighting especially in evening. In thiscase, sun panel capacity, battery, BCR, and inventers will be determined. This study also aims giving information about investment cost which is needed by PLTS with battery without battery and PLN. The calculation in this study used data from BMKG Meteorology Station Palu and Mineral Sources (ESDM) office of Central Sulawesi. The results showed that the capacity power for supplying Air Conditioner charge and lighting in evening was 122,54 kWh, where the systemsvoltage was 120 volt. moreover, the number of sun panel was 40 unit with capacity 200 Wp, 15 unit for battery with capacities 24v 1000Ah.Keyword : Photovoltaic design, Battery, BCR, Inverter, Early Investment

Abstract

The scarcity of fossil fuel sources and the growing energy demand has resulted in more intensively searching for alternative energy. One alternative energy source that is suitable for the equatorial region is solar energy. One of the technologies for utilizing solar energy that has begun to be widely used in Indonesia is the photovoltaic (PV) system. The output of PV is highly dependent on environmental conditions, especially the intensity of the sun and temperature. In addition to these two factors, shading (shadows) and soiling (dust) also affects the PV output. So, this must be observed at all times by monitoring the voltage and current as the PV output. This study aims to design a PV panel instrumentation structure based on a data logger. PV output data in the form of voltage and current and environmental conditions such as ambient temperature and solar intensity were recorded in real-time. The measurement results from the data logger will be compared with manual measurements. PV output data, output voltage and current, as well as sunlight intensity were compared with measurements using an avometer. Temperature data will be compared with thermocouple measurements. PV in this study will be connected to a 1kOhm load resistor. The results of the data logger and manual measurements indicated an insignificant difference. The manual measurement was conducted every hour, from 09.00 – 16.00. The maximum differences for voltage, PV output current, pyranometer voltage, and ambient temperature are 0.89 V, 0.0007 A, 0.00014 V, and 0.25oC, respectively.

Abstract

Renewable energy is an energy source that can be utilized continuously and is available by nature. One example of using renewable energy is photovoltaic. Photovoltaic is a tool used to absorb solar energy and convert it into electrical energy using the photovoltaic effect method. This research aims to monitor the salinity (salt content) of sea water by utilizing solar energy using the Buck Converter type DC to DC Converter method to regulate and reduce the higher voltage to a lower voltage to be loaded on the microcontroller as the reading output. This research was designed using a 20 WP photovoltaic with a maximum voltage of 20 volts which functions as a power supplier or energy source whose voltage is then reduced by a buck converter circuit to a smaller voltage of 5 volts to be charged to the Arduino Uno in processing salinity measurement data using a TDS sensor. as a measuring tool. The test results of the equipment show that the DC to DC Converter circuit is successful in reducing the photovoltaic voltage so that it can operate the microcontroller.

Abstract

Hydropower plants (PLTA), micro-hydro plants (PLTMH), and pico-hydro plants (PLTPH) in Indonesia use generators with excitation systems to generate fields or magnetic field amplifiers. The use of excitation systems in generators has several drawbacks. In the era of technological development, various types of generators have been developed, one of which is the permanent magnet generator. The Permanent Magnet Synchronous Generator (PMSG) has separate excitation from the synchronous generator and is carried out by permanent magnets to generate the magnetic field instead of coils. This research aims to explore the potential of irrigation channels being utilized as PLTPH using permanent magnet generators. The research method used is the experimental method. The experimental research method is a true experimental method where the equipment is tested and examined. Experimentation involves observation under artificial conditions, where these conditions are created and controlled by the researcher. This study shows that the irrigation channel in Porame Village has the potential to be used as a Pico-Hydro Power Plant (PLTPH) to provide electrical energy as an alternative lighting source, especially at night and during power outages from the national electricity grid (PLN). From the measurement and calculation results, the water flow rate at night is 0.3835 m³/s, with the water power being Pair = 1,901 watts. The type of turbine used is a crossflow turbine, utilizing a permanent magnet synchronous generator.

Abstract

Investigating coconut water as inhibitors to protect low-carbon steel from corrosion in 3.5% NaCl has been studied by weight loss method. The weight loss of steel was identified by immersion test. The coconut water used was young and old coconut water. The concentration of coconut water, whether young and old, in 3.5% NaCl was varied. The results showed that the corrosion rate of steel decreased with increasing coconut water concentration. Furthermore, old coconut water can further reduce the rate of corrosion in mild steel comparing young coconut water.
