Abstract

Abstrak: Kajian Komputasi dan Eksperimental Pengaruh Kontrol Aktif terhadap HambatanAerodinamika Model Kendaraan. Dinamika aliran udara sangat dipengaruhi oleh pembentukan separasi di sekitar bodi kendaraan. Separasi aliran menjadi pemicu perbedaan tekanan yang signifikan antara sisi depan dan belakang sehingga muncul efek tarikan ke arah belakang sebagai kontributor utama besarnya hambatan aerodinamika yang diterima kendaraan. Penelitian ini fokus pada kajian hambatan aerodinamika dengan memperhatikan karakteristik pola aliran yang terbentuk dan distribusi tekanan pada dinding belakang model kendaraan melalui metode simulasi komputasi dan eksperimental laboratorium. Kontrol aktif tiupan ditempatkan pada sisi atas dinding belakang Ahmed model dan diatur pada kecepatan 1.5 m/s. Hasilnya menunjukkan bahwa penggunaan kontrol aktif tiupan pada sisi belakang mampu menunda separasi, meningkatkan koefisien tekanan, dan mengurangi hambatan aerodinamika model kendaraan. Abstract: Computational and Experimental Studies of the Effect of Active Control on Aerodynamic Drag of Vehicle Models. The dynamics of air flow is strongly influenced by the formation of separations around the vehicle body. The flow separation triggers a significant pressure difference between the front and rear sides so that a rearward pull effect appears as the main contributor to the amount of aerodynamic drag received by the vehicle. This research focuses on the study of aerodynamic resistance by paying attention to the characteristics of the flow pattern formed and the pressure distribution on the rear wall of the vehicle model through computational simulation methods and laboratory experiments. The blowing active control is located on the upper side of the back wall of the Ahmed model and is set at a speed of 1.5 m/s. The results show that the use of blowing active control on the rear side is able to delay separation, increase the pressure coefficient, and reduce the aerodynamic drag of the vehicle model.

Abstract

Air merupakan sumber utama dalam kehidupan manusia dan makluk hidup lainnya, serta menunjang keberlangsungan hidup. Sehingga dalam pengabdian yang dilakukan adalah perhitungan kebutuhan air bersih dengan hasil perhitungan kebutuhan air bersih sebesar 14.718 liter perhari. Untuk mendapatkan kualitas air bersih dan debit yang dibutuhkan maka dilakukan metode geolistrik, electric logging dan uji sampel dilaboratorium. Hasil penelitian menunjukkan bahwa pengambilan sampel geolistrik dapat menentukan kedalaman sumur bor dengan kedalaman 100 meter dapat memberikan debit yang memenuhi kebutuhan. Hasil electrik logging memberikan gambaran lapisan-lapisan dalam tanah sehingga mudah dalam menentukan titik pompa yang berkisar antara 52-60 meter dan titik screen berkisar antara 32-52 dan 60-72 meter.  Hasil kualitas air yang telah dilakukan pada laboratorium Dinas Kesehatan Pemerintah Provinsi maluku dengan hasil derajat keasaman sebesar 7,2 % dari total kadar yang diperbolehkan sebesar 6,5-8,5 %.

Abstract

Community learning activity center (PKBM) in general as an institution engaged in the world of non-formal education (PNF) with the aim of being a center for community learning activities. PKBM as a community forum for learning has many functions, especially those related to the implementation of the development of non-formal education activities. The main problem in improving the skills or skills of technicians in the maintenance and repair of motorcycles is the limited teaching resources and the importance of supporting materials or theories as well as the availability of incomplete practical support tools, as a result, when students graduate their knowledge is far behind what is needed in the world of work. Departing from obstacles or deficiencies in the community learning activity center (PKBM) Timuato Village, Kec. Blue lake district. Gorontalo, sees an opportunity to do service to help provide solutions to existing problems, namely providing training on "Training to Improve Motorcycle Technician Skills in Supporting the 2022 Job Skills Program", which is intended for PKBM students, with the aim of fostering and improving skills towards PKBM advanced, prosperous and independent.

Abstract

The need for electrical energy has become one of the basic needs for human life, the limitations and capabilities of the state electricity company in providing electricity to the Indonesian people have not been met. Like a village that has not been reached by PLN electricity. The purpose of this study is to determine the output power of a micro hydro power plant using a flat blade, the load variation used is 1 kg to 15 kg, and to determine the characteristics of the waterwheel, then describe the power and efficiency curve using a flat blade on the type Undershot stream. The method used in this research is to measure power efficiency by varying the flow rate of 0.0166 m3/s and 0.0155 m3/s. The flow rate measurement is carried out by filling a bucket with a bucket volume of 20 L. The results obtained in this study are the largest discharge is found at 0.0166 m3/s discharge to get a power of 12.127 Watt, resulting in a waterwheel efficiency of 18.569% at 56 axis rotation 23 rpm.

Abstract

The need for electrical energy today is starting to increase along with the increase in population and rapid development, but inversely proportional to the progress or innovations in increasing renewable energy. Given that this renewable energy can be developed continuously and operational costs are relatively cheap, the electricity that relies on coal (fossil) over time will run out and cannot be renewed, the discussion concerns the supply of PLN supplies. So that in this study the focus is on the utilization of electrical energy for the NUWSP development area of Gorontalo Regency Biyonga Village and calculating the total consumption needs of the electrical energy used. After research and data analysis, the results obtained are 189 kVA or 189,000 vA, the total peak demand with load is 3 units of centrifugal pumps, 10 points of room lighting, and 12 points of lighting around the building, the results of the analysis obtained became a reference and suggested to install electrical energy with a capacity of 197 kVA or 197,000 vA with the consideration that when development occurs, the demand for electrical energy is still sufficient from what is installed.

Abstract

This research aims to evaluate the influence of using air as a coolant on photovoltaic module's power output and electrical efficiency. Fossil energy, as the primary energy source today, has limited supply and presents challenges in meeting future energy demands. In an effort to address this issue, we conducted tests by implementing an air cooling system using a blower at the bottom of the photovoltaic module. The tests were conducted with varying air flow rates, and the results indicate that the use of air cooling can enhance the power output and efficiency of the photovoltaic module. The average power output increased by 31.66 Watts with an efficiency of 3.52%. However, when the air flow rate increased by 1.5 m/s, there was an average power decrease of 28.9 Watts and an efficiency decrease of 3.22%. These findings demonstrate that air velocity affects the temperature, power output, and efficiency of the photovoltaic module.

Abstract

The Anggrek Unit Steam Power Plant (PLTU) is a power generation facility whose construction began in 2007 and began operating in 2019 with a capacity of 2 x 25 MW. Since its inauguration, PLTU Anggrek has become one of the main sources of electricity distribution in Gorontalo Province, so the frequency of power outages in the area has now decreased significantly. The water supply system for fire fighting uses BSP pipes. In this research, the aim is to determine the active fire protection system. This research was carried out with a qualitative descriptive design with data collection: observation and interviews. The assessment of the results of existing suitability will be assessed using descriptive percentage calculations. The research results show that of the 7 variables discussed, the average value for the level of fulfillment is 98.57%. Based on the level of fire audit assessment that meets the requirements of Indonesian national standards and international standards, the results are in the Good criteria or have met the requirements.
