Currently, the energy we use comes from the use of fossil energy. In the future, fossil energy will experience a reduction and will eventually run out because it has limits to its availability. One way to reduce the impact of dependence on the use of fossil energy is to utilize wind energy sources, which are one of the environmentally friendly renewable energies. Currently, the use of wind energy continues to be developed, one of which is a wind energy conversion system which utilizes wind energy sources into electrical energy by converting wind kinetic energy into mechanical energy through wind turbine blades and then converting it into electrical energy through a generator. In this research, we examine how a horizontal shaft wind turbine performs with variations in the number of blades with the aim of obtaining optimal performance coefficient values. The tests carried out in this research were with simulations on Q Balde v 0.96 software with variations in the number of blades from 3 - 5 with a wind speed range ranging from 3 m/s – 12 m/s. The research results show that the best CP value is the 4 blade horizontal axis wind turbine which has a CP value of 6% compared to the 3 blade wind turbine with 4 blades, while the 4 blade horizontal axis wind turbine with 5 blades has a CP comparison value of 4%. Keywords: Fossil energy, renewable energy, performance coefficient, wind turbine, wind energyAbstract Currently, the energy we use comes from the use of fossil energy.

Pemberdayaan Dosen Dan Editor Jurnal Ilmiah Di Lingkungan Unjani Dalam Pengembangan Sistem Repositori Publikasi Ilmiah Unjani Najmurrokhman, Asep; Hardian, Arie; Murniati, Anceu; Saefudin, Deny Bayu

Pemeringkatan perguruan tinggi telah menjadi acuan dalam menilai kualitas sebuah perguruan tinggi. Parameter pemeringkatan didasarkan atas data yang terlacak mesin pencari laman yang meliputi data repositori publikasi ilmiah dan faktor dampaknya. Universitas Jenderal Achmad Yani (Unjani) sudah memiliki wadah untuk menyimpan publikasi ilmiah yang dimiliki secara individu maupun yang diterbitkan dalam bentuk jurnal ilmiah. Namun demikian, data publikasi ilmiah yang dimiliki oleh para dosen belum banyak tersimpan didalamnya. Kondisi lain terkait jurnal ilmiah yang dimiliki setiap fakultas dan universitas juga tidak begitu menggembirakan. Data artikel yang dimuat dalam jurnal tidak diperbaharui bahkan masih banyak jurnal yang terlihat berhenti beraktivitas. Kondisi tersebut menyebabkan kinerja penelitian institusi yang diukur dari publikasi ilmiah dosen menjadi sulit dievaluasi dan ditentukan indikator keberhasilannya. Selain itu, saat ada penilaian proses akademik dan penilaian kinerja penelitian dan publikasi masih harus ditempuh secara manual. Hal tersebut mengganggu proses integrasi data dan penilaian secara komprehensif terkait profil penelitian institusi. Untuk mengatasinya, sebuah upaya sistematis harus dilakukan dalam memanfaatkan repositori tersebut. Makalah ini menguraikan tentang kegiatan pengabdian masyarakat yang dilakukan berkaitan dengan pemberdayaan dosen dan pengelola jurnal ilmiah dalam membantu pengembangan repositori publikasi ilmiah Unjani.

Abstrak: Unjani Motoris Community (UMC) merupakan komunitas pengendara motor beranggotakan para pegawai Unjani yang memiliki jiwa kebersamaan dalam rangka mempromosikan Unjani melalui kegiatan touring yang dilakukan dengan mengendarai sepeda motor. Kondisi darurat baik terkait dengan kesehatan, keselamatan pengendara dan keadaan darurat akibat tidak berfungsinya kendaraan menjadi hal yang dapat mereka hadapi di perjalanan, sehingga pengetahuan dan keterampilan untuk keselamatan, penanganan awal keadaan darurat baik dalam aspek kesehatan dan keselamatan jiwa maupun performa kendaraan, sangat diperlukan. Permasalahan yang dihadapi para anggota UMC adalah masih rendahnya pengetahuan dan keterampilan tentang penanganan awal trauma pada kecelakaan lalu lintas dalam melakukan pertolongan pertama, masih rendahnya keterampilan dalam mengidentifikasi trauma yang mengancam keselamatan jiwa, dan belum optimalnya pengetahuan dalam menangani kondisi darurat akibat gangguan fungsi kendaraan bermotor. Solusi yang ditawarkan untuk mengatasi permasalahan tersebut adalah melalui sosialisasi dan pendidikan tentang penanganan awal trauma pada kecelakaan; pelatihan pelepasan helm, evakuasi korban, pemasangan bidai dan pelatihan memperbaiki kerusakan kendaraan bermotor dalam keadaan darurat. Berbagai program yang telah dilaksanakan oleh Tim Pengabdian Masyarakat FK Unjani yang bekerjasama dengan FTM Unjani pada akhirnya mampu meningkatkan pengetahuan dan keterampilan para anggota UMC dalam mendeteksi dan melakukan penanganan awal trauma pada kecelakaan dan penanganan keadaan darurat pada kendaraan bermotor. Kata kunci: darurat, motor, trauma, UMC.

Several agricultural areas in Indonesia are classified as underdeveloped rural areas, and challenging to acquire electricity from the primary grid. On the other hand, some pico hydropower potentials can be found in agriculture, especially at the irrigation dam spillway flows. However, no such technology can convert the energy inside the water open-channel flow through dam spillways into electricity. Crossflow turbines (CFT) are expected to utilize dam spillways’ power due to their ability to convert the kinetic energy of water. Prior studies found that airfoil profile could slightly increase CFT efficiency and affect the interaction between water and turbine. Using planar two-dimensional computational fluid dynamics (CFD) numerical simulation analysis, the current study investigated the energy conversion phenomenon inside different open-channel CFT blade profiles. This study simulates CFT working at 3 meters of total head and 0.04 m3/s of water discharge put into the dam spillway’s downstream. The turbine blade profiled with the National Advisory Committee of Aeronautics (NACA) standard airfoil numbered 9405, 9503, and 9506 are being compared and investigated in the present study. CFD numerical analysis results show that the forward direction NACA airfoil profiled blades deliver better efficiency than the reversed one. These findings contradict the prior study’s results which tested airfoil profiled CFT working as usual with nozzle. This phenomenon indicated differences in the energy transfer process between open channel CFT and the ordinary CFT with a nozzle. Furthermore, current work finds that forward NACA-9503 CFT has a higher efficiency than other tested airfoil profiles, with 57.05% efficiency. In addition, the present study finds that the NACA-95XX airfoil has a more suitable chamber curve with the original CFT blade’s curve than the NACA-94XX airfoil by velocity triangle analysis. Then, the NACA-9503 profile is thinner than the NACA-9506 profile, which eases water flowing through the turbine blades.
