One of the ways to preserve energy on the air plane is by decreasing the drag. Drag is closely related to the flow separation, the faster the separation, then the drag will increase more. Because of that, efforts were conducted to decrease drag is by manipulating a fluid flow field that is by installing triangle rod obstacle in front of the cylinder. The purpose of this research is to analyze the effect of installing triangle rod obstacle in front of the cylinder by various air flow velocity on the drag cofficient. In this research, the experiment was conducted in the wind tunnel, which consists of blower, pitot pipe, manometer, cylinder pipe, and triangle rod. The air flow velocity was varied from 6.25 m/s, 5.01 m/s, 4.09 m/s, 3.17 m/s, 2.24 m/s .The Reynold number based on cylinder (D = 42 mm) and air flow velocity is Re =18.100, 14.500, 11.800, 9.170, 6.480 .The distance triangle rod and cylinder is L = 70 mm or L/D=1.67.Pressure distribution is achieved by measuring the cylinder surface on 36 spots with interval of 100. The measured data was pressure of cylinder surface, static pressure, and airflow speed. The research results showed that the triangle rod could decrease the drag of cylinder. Coefficient drag for cylinder without triangle rod was 0,1276 while the less triangle rod was 0,01882 which takes place at speed 6,2479 m/s.

The energy used as a dryer is usually only a single type of energy. In this case, study is conducted on the natural flowdryer system by using the chimney. This combination of energy utilization of solar energy and biomass that can be used simultaneously or one turns in accordance with the needs or circumstances. It has been tested against a dryer prototype by performing measurements on the temperature of the inlet air and exit on biomass furnace, the temperature of the inlet air and exit on the solar collector, the temperature of inlet air and exit on the drying chamber, the water content of dried material, the temperature of dried material, the surface temperature of inside and outside of wall on drying chamber, and the intensity of solar radiation. Data were collected at an interval of 30 minutes and do the processing of such data. Next made in a graphical form of thermal energy balance and system efficiency versus the time. Results obtained that: the drying time was 7.5 hours. Thermal energy balance versus the time found that the increase of energy losses lead to useful energy reduction system.

Road condition and plain all of the line traffic Denpasar- Gilimanuk have many slope upward. Beside of many slope upward declivity and long slope upward have many variation too. We must give many attention for that condition in design minimum power engine to vehicle truck,beside the other factors like wind velocity , kind of asphalt , curves ,etc. The purpose of this research to recite road condition (slope upward , wind velocity ,density) all of the line traffic Denpasar – Gilimanuk,and then will be count minimum traction need of vehicle truck that across that road. From this research result obtained that the needed traction to overcome all resistance especially slope upward resistance are 6000 N and the estimate needed power about 220 hp from characteristic power torsi.

Pada umumnya abon dibuat dari suwiran daging sapi atau daging ayam, namun saat ini telah berkembang aneka olahan abon yang lebih variatif dari aneka bahan seperti ikan, belut, udang, lele, telur dan masih banyak jenis abon lainnya. Peluang membuat usaha abon telur dilirik oleh salah satu kelompok usaha di desa Baluk, kecamatan Negara, kabupaten Jembrana. Kelompok Wanita Tani (KWT) Pitik Jaya di Banjar Rening, desa Baluk mempunyai peluang besar mengembangkan usaha pembuatan abon telur, karena didukung oleh bahan baku telur itik dan telur ayam yang dihasilkan sendiri oleh kelompok usaha tersebut. Usaha pembuatan abon telur sudah dimulai pada tahun 2014. KWT Pitik Jaya mempunyai permasalahan yang berkaitan dengan effisiensi dan produktifitas dimana permasalahan ini disebabkan oleh alat/sistem penirisan minyak abon masih konvensional dengan menaruh abon diatas niru. Upaya untuk mengatasi permasalahan yang ada, maka tujuan dan luaran dari kegiatan adalah merancang dan manufaktur mesin peniris minyak abon yang dapat menghasilkan produk abon telur lebih banyak dan lebih baik dibanding dengan penggunaan alat/cara konvensional. Mesin juga dapat dioperasikan untuk penirisan minyak produk yang lain. Tim berhasil merancang mesin peniris minyak abon multi fungsi dengan kapasitas 400 butir telur per hari. Jadi pemanfaatan mesin ini meningkatkan produktifitas mencapai 500% dan juga meningkatkan kualitas abon telur produksi KWT Pitik Jaya.

The Negara city is an area that has already quite crowded, shown by the availability of many facilities, sosmall industrial/business group are emerging, one of which is an industry or group of enterprises manufactureof cassava chips "Niki Suka". Meanwhile, in the eastern region of of Bali island, there are UD. Gurih Sari, isa small industry that produces cassava chips as well . Production of chips is still utilizing local resourcesandproduced conventionally. UD Gurih Sari and Suka Niki Suka business groups, both have a similarproblem that is related to productivity, caused by small capacity and conventional of cassava cutlery/slicer, aswell as low educational background of human resources (HR). The aims of the activity is to generate cassavaslicing/cutting machine. Solutions or methods offered in this program is to replace the equipment or theconventional way with a cassava mower/slicer. Technical planning activities of our team was using someinput from business groups partner. The next activity in introducing the good management "of the company "that was dealed and desired by the partner. Then continued by the introcudtion of work safety. The firstcommunity service activities held on August 22, 2015 at Niki Suka women business group, located in thevillage Cupel, Negara, Jembrana District, Bali. The activities began with a demo making cassava chipsconventionally by Niki Suka women business group, continued by introducing and demonstrating themachine that we made. This training can improve the skills of the workforce in producing cassava chips.

Tujuan pengabdian ini adalah untuk mengetahui hasil implementasi ergonomi pada pengerajin seni ukir batuparas di desa Sakti. Desa sakti adalah salah satu desa di Kecamatan Nusa Penida,dimana beberapa diantarapenduduknya ada yang menekuni pekerjaan sebagai pengerajin seni ukir batu paras. Batu paras ukirumumnya digunakan untuk bangunan tempat suci seperti pura dan sanggah, serta sebagai aksesoris bangunanrumah. Pengerajin seni ukir paras pada umumnya bekerja dalam ruang/bangunan darurat dengan peralatankerja yang sederhana. Kondisi dan lingkungan kerja sangat tidak nyaman, hal ini karena tempat kerjanyaberupa emperan, terpapar panas matahari, angin, dan debu. Sementara sikap kerja pengerajin juga tidakalamiah,dengan peralatan yang tidak sesuai antropometri. Kondisi demikian menyebabkan pekerja cepatlelah, mengalami gangguan muskuloskeletal, dan nyeri pinggang serta berdampak pada rendahnyaproduktivitas. Untuk mengatasi masalah ini maka dilakukan intervensi ergonomi berupa penggunaanlandasan sebagai alas benda kerja, penggunaan tempat duduk, pelatihan cara mengangkat beban, danmembiasakan memakai alat pelindung diri (APD). Untuk mempercepat proses pemotongan dan penghalusanpermukaan disumbangkan satu unit alat electic cutter circle. Hasilnyadapat dilihat daricara dan sikap kerjayang sudah alamiah, cara mengangkat beban dengan teknik squat, dan kebiasaan menggunakan masker.Dengan demikian dapat disimpulkan aplikasi ergonomi dapat meningkatkan kenyaman dan produktivitaskerja.
