Abstract

The blade is the most critical part of turbine design because it is used to convert kinetic to mechanical energy. In general, the blade types used for ocean wind turbines are taper and taperless blades, like those operated at Ciheras Coastline. Previous research has been analyzed the type of airfoil used in designing taper blades for ocean wind turbines using NACA 4412, which was selected as the optimal foil configuration at sea wind speeds of 12 m/s. In this study, the comparison of taper and taperless blade designs using NACA 4412 at a wind speed of 12 m/s is analyzed. The comparative study with previous research has been carried out and resulted in the same graphical patterns and performance results. In this study, the focus is on investigating the performance coefficient of power, mechanical power, and electrical power. The final result shows that taper blade designs are highly recommended for use in ocean wind turbines compared to taperless blades. In general, the performance produced by taper blades is more significant than taperless blades at relatively high wind speeds. The maximum performance coefficient of power, mechanical power, and electrical power generated by the taper blades in sequent are 0.47, 1535 watts, and 786 watts, while the taperless blades have 0.44, 1437 watts, and 736 watts.

Abstract

Telur mempunyai sifat mudah rusak (perishable) yang disebabkan karena penurunan kualitas telur ayam. Pecahnya kulit telur juga dapat disebabkan karena kesalahan proses pengambilan, pengangkutan dan penyimpanan telur. Proses pengangkutan telur ayam pada skala UKM (Usaha Kecil Menengah) dilakukan secara manual yaitu diangkut oleh manusia dari kandang menuju tempat penyimpanan. Permasalahan lain yang timbul pada proses pengangkutan secara manual adalah tenaga yang besar dan waktu yang lama, sehingga membutuhkan tenaga kerja khusus. Efek lain dari pengangkutan manual adalah dapat menimbulkan kelelahan dan penurunan fungsi fisik. Sehingga dibutuhkan alternatif alat pengangkut telur. Kondisi lingkungan kandang ayam yang sempit dan bergelomang perlu diperhatikan dalam proses perancangan alat. Rancang bangun alat menggunakan sistem peredam getaran dan memperhatikan aspek ergonomi dengan analisis Rapid Upper Limb Assessment (RULA) menjadi solusi yang ditawarkan agar tetap nyaman digunakan. Pengujian pada lahan yang berbeda yaitu beton dan tanah yang memiliki permukaan yang bergelombang. Hasil rancangan desain alat pengangkut telur memiliki kemampuan meredam hingga 2742.43 Ns/m, kapasitas rata-rata angkut 49.74 kg/menit atau setara mengalami peningkatan 22.44%, jumlah pekerja dapat ditekan 50%, biaya pengangkutan dapat ditekan sebesar 28% jika dibandingkan dengan cara manual. Analisis RULA menunjukkan pengangkutan secara manual memiliki skor 6 artinya resiko aktivitas tinggi dan perlu dilakukan perbaikan, sedangkan pengangkutan menggunakan alat memiliki skor 4 artinya desain alat dapat diterima.

Abstract

Indonesia mempunyai potensi energi arus laut sebesar 17.989 MW, yang telah diratifikasi oleh Asosiasi Energi Laut Indonesisa (ASELI) pada tahun 2014. Hasil survei tersebut menunjukan bahwa kecepatan arus laut di Indonesia tergolong rendah, namun potensinya sangat besar. Potensi tersebut belum dimanfaatkan secara optimal untuk menutupi kekurangan rasio elektrifikasi di Indonesia. Adapun dalam memanfaatkannya dibutuhkan teknologi turbin untuk mengkonversi menjadi energi listrik. Turbin yang dapat bekerja pada kecepatan arus rendah adalah tipe vertikal sudu lurus, namun efisiensi yang dihasilkan masih cukup rendah. Sehinngga, penelitian ini bertujuan untuk meningkatkan performa turbin arus laut tipe vertikal dengan menambahkan water flow deflector. Prinsip kerja deflector berdasarkan Hukum Kontinuitas, yang mana dengan memperkecil luas permukaan input maka arus laut yang mengenai turbin akan meningkat sehingga menghasikan putaran dan torsi yang lebih besar. Metode yang digunakan dalam penelitian ini adalah, eksperimen karena lebih mendekati dengan kondisi aktual. Hasil akhir penelitian ini telah menunjukkan bahwa, water flow deflector telah meningkatkan performa turbin sebesar ....%. Sehingga, water flow deflector sangat direkomendasikan untuk diterapkan di wilayah perairan Indonesia yang cenderung berkecepatan arus rendah.

Abstract

ANALYSIS OF THE LEVEL OF COMMUNITY SATISFACTION ON THE APPLICATION OF MICRO-HYDRO GENERATORS AS A SOURCE OF ELECTRICAL ENERGY IN BATU SAENG, LAMPUNG. Generator-Micro hydro is a very important component for hydroelectric power in meeting the electricity needs of the community. Batu Saeng is one of the areas in Lampung Province that still lacks electricity. The people there are always hydropower. However, based on a team survey, several components are no longer suitable for use, one of which is a generator. This old generator with a capacity of 8000 watts has been used by the people of Batu Saeng, but its condition is currently rusty, almost burnt, and is no longer suitable for use. This condition is due to economic problems that make it impossible to replace micro-hydro plants. Therefore, the community service team helped replace a newer generator with a larger capacity of 10,000 watts. A 10,000 watt micro hydro power plant has supplied electricity to 20 houses in Batu Saeng. The community service team also obtained data from the community satisfaction survey on the application of the 10,000 watt micro hydro generator. The scope consists of administration, procedures, communication, engineering, and generating equipment. The analysis results show that 100% of the people are very satisfied with the implementation of the micro hydro generator by the service team.

Abstract

APPLICATION OF HYBRID ENERGY TECHNOLOGY: MİCRO-HYDRO TURBİNE AND SOLAR PANELS TO INCREASE ELECTRİCAL ENERGY PRODUCTİON İN DUSUN BATU SAENG, TANGGAMUS, LAMPUNG. Dusun Batu Saeng, Tanggamus, Lampung is one of the areas that utilize the potential of the surrounding natural resources. One of the potentials used is river water which is used as a Micro Hydro Power Plant (PLTMH). However, the source of electrical energy that has been used for 10 years does not appear to be optimal in its utilization. This is because many components are damaged and unfit for use which has reduced their performance. The production of electrical energy from PLTMH is 8 kW which is distributed to 20 houses, this amount will be reduced during the dry season to 6-7 kW. Based on that, it is necessary to replace components such as turbines and generators with a capacity of 10 kW. In addition, during a prolonged dry season, it can also be utilized by installing a 1 kW photovoltaic as a Solar Power Plant (PLTS). Thus, by utilizing water and solar sources, more optimal electricity production can be produced through hybrid energy from PLTMH and PLTS in Dusun Batu Saeng, Lampung. The implementation stages include literature study, site survey, group discussion forum, design and planning, design and preparation, manufacture of PLTMH and PLTS, installation of PLTMH and PLTS, monitoring and evaluation, and final report. The result of this program is an increase in electricity production from 8 kW to 11 kW of hybrid energy from PLTMH and PLTS. It is hoped that in the future this program can be applied to other areas so that they become energy-independent communities.
