Abstract

Institut Teknologi Sumatera (ITERA) has 5 reservoirs with lip embankment construction higher than the normal water level and have steep elevations with different catchment areas (DTA). By using the Google Earth Pro software, it is known that DTA reservoirs A, B, C, D, and E are respectively 1.728 ha; 1,146 ha; 1,052 ha; 0.844 ha; and 9.562 ha. This study aims to determine the potential energy that might be generated from the 5 reservoirs while still considering the integrity of the ecosystem. The power plant is in the form of a Pico hydro power plant that can be used as a power plant practicum media by Itera students, especially electrical engineering study program students. The power plant's rapid pipe is designed to be installed 1 meter below the normal water level and the operating time is based on the rain discharge that is accommodated by the reservoir in one month. The method used is field observation, rainfall data collection, calculations using practical rational methods and hydropower hydraulics. The results of data processing of five reservoirs owned by ITERA show that the greatest potential that can be used as a source of electricity generation is reservoirs E. The analysis shows that the discharge capacity of 0.216 m3 / s and an effective head of 5.46 m can produce an electric power generated of 7,071 kW with operational time at April.Keywords : Discharge, Rain Intensity,  Pico Hydro.AbstrakInstitut Teknologi Sumatera (ITERA) memiliki 5 embung dengan konstruksi bibir embung  lebih tinggi dari batas muka air normalnya serta memiliki elevasi curam dengan luasan Daerah Tangkapan Air (DTA) masing masing-nya berbeda.

Abstract

The need for drinking water is one of the basic needs that must be met by humans, drinking water has various kinds of compounds and bacteria in it. Drinking water is generally the result of processing with various methods, one of which is the use of nonthermal plasma technology. With the presence of non-thermal plasma technology to kill bacteria such as e-coli and other microorganisms with a working system that eliminates bacteria in the air. This looks effective when we use plasma because with high voltage the bacteria will die. In well water which is usually used for cooking and drinking in households, the bacteria or microorganisms in it are not completely killed. This water purification system is very useful if it is developed especially in areas that have not been reached by clean water or PDAM, in rural areas it is estimated to be very effective. This tool works well. Generally, in rural areas, the use of the latest technology is not too much. With the addition of a part of a microcontroller system and a monitoring system in the form of a website, it is very easy to operate this tool, we can combine the PH and TDS of the water we are going to purify. Equipped with a microcontroller system that makes it easy to control something and run tool commands. Keywords: Non-Thermal Plasma, PH, TDS, Microcontroller System, Monitoring System

Abstract

Hydropower plants are increasingly being heard nowadays, but the growth is still very lacking, especially for residents living in rural and coastal areas. At present several efforts have been made by the government, including the existence of a system of purchasing electricity from small-scale renewable energy generation and the construction of new transmission networks. Pesisir Barat Regency is part of the South Lampung region, Sumatra. This region has a population distribution in the coastal area and is surrounded by Bukit Barisan National Park. So that there are many large river streams that can be utilized by the local community. Large rivers have the potential to be utilized further as hydropower renewable energy sources. River potential is seen by conducting river location surveys, flow measurements and river heads and power calculations. Based on the analysis of measurement results there are two rivers that have the potential to be a micro or mini hydro generator; Way Laai and Way Lami. The maximum design discharge of Way Laai of 4.52 m3/s can produce a mechanical output power of 1223.82 kW with an effective head of 44.16 m. Way Lami with a design discharge of 5,336 m3/s, an effective head of 28.8 m has the potential to provide a mechanical power output of 942.23 kW. Sequentially, with this mechanical output power, the Way Laai and Way Lami rivers, can meet the electricity needs of the community with an installed power of 900VA as much as ± 1350, ± 25100 Houses.

Abstract

Pentanahan merupakan hal penting untuk melindungi sistem tenaga listrik. ITERA sebagai kampus baru dan pada tahap pengembangan membutuhkan pengujian sistem pentanahan untuk rencana pembangunan fasilitas dan fasilitas pendukung kegiatan kampus. Semua bangunan harus memiliki keandalan pentanahan sehingga gangguan pada peralatan listrik dan elektronik tidak membahayakan keselamatan. Faktor tanah menjadi salah satu parameter penting karena memiliki karakteristik nilai resistansi berbeda yang tergantung pada jenis tanah, jenis sistem pentanahan, suhu, kelembaban, kandungan elektrolit dalam tanah dan lainnya. Untuk alasan ini, perlu untuk membangun sebuah sistem yang cocok dengan karakteristik tanah ITERA sehingga nilai resistansi tanah yang kecil tercapai dan mencapai titik aman, maksimum 5 ohm (PUIL 2000). Uji pentanahan dilakukan dengan menggunakan metode variasi kedalaman dari dua jenis elektroda dan variasi konsentrasi dua jenis zat tambahan. Pada penelitian ini digunakan garam dan bentonite sebagai zat campur tanah. Pada kondisi awal dengan variasi kedalaman 20 cm hingga 100 cm pada dua jenis elektroda tanpa penambahan zat tambahan diketahui bahwa resistansi bumi di atas 5 ohm yang tidak mencapai kondisi aman. Penambahan bentonit dan garam menyebabkan resistensi tanah berkurang dengan meningkatnya konsentrasi zat aditif dan meningkatnya kedalaman implantasi elektroda. Nilai resistansi tanah yang aman dapat diperoleh dengan menggunakan elektroda mesh pada konsentrasi 7 kg garam dengan kedalaman 30 cm dan 40 cm pada konsentrasi 7 kg bentonit, sedangkan menggunakan elektroda batang, nilai aman dapat diperoleh dengan menambahkan 7 kg garam atau 7 kg bentonit pada kedalaman 80 cm.

Abstract

Hydropower is considered to be one of important renewable energy sources. Renewable energy is the second-largest contributor to global electricity production after fossil fuel. Hydropower generation presents several advantages over most other sources of electrical power. It includes a high level of reliability, proven technology, high efficiency (about 90%), very low operating and maintenance costs, flexibility and large storage capacity. Based on the types of installation, hydropower can be categorized as; impoundment, diversion, and pump storage, and based on the turbine types can it be classified as reaction and impulse systems. Previous research gives the results of the initial survey, concluding that there are two rivers that have the potential to become a micro or mini-hydro generator. Way Laai and Way Lami. So, we need to know what is turbines type to suit both of river Way Laai and Way Lami. We used the same method with other research that used TURBNPRO software for helping in the design of Turbines. The simulation result gives one alternative to the right turbine design for Way Laai is the orientation vertical of 6 jet Pelton with a peak efficiency of 89.9%. The right alternative turbine design for Way Lami is the vertical orientation Axial turbine/ propeller design with a peak efficiency of 93.3%.
