Abstract

Ajang lomba dayung tradisional menjadi hiburan yang menarik dikalangan masyarakat nelayan di pesisir pantai utara pulau jawa. Permasalahan yang sering muncul dalam lomba dayung tradisional ini yaitu terjadi pada saat melakukan start dan saat finish. Penelitian ini bertujuan untuk merancang prototype teknologi garis start dan finish pada lomba dayung tradisional. Pada penelitian ini, metode yang digunakan meliputi tahap perancangan, pembuatan dan pengujian. Desain perancangan menggunakan bantuan software proteus versi 7.7 SP2 Pro. Pembuatan program pada mikrokontroler dikerjakan dengan menggunakan bantuan software Arduino IDE versi 1.5.8. Kesimpulan yang diperoleh dari penelitian ini yaitu prototype teknologi garis start dan finish meliputi pengujian hardware, pengujian pada program mikrokontroler, pengujian sensitivitas Light Dependent Resistor didapatkan sistem elektronika bekerja dengan baik sesuai perencanaan. Pengujian pada hardware didapatkan bahwa komponen dan koneksi terhadap soket pada kabel penghubung menempel dengan kuat serta casing pada modul tahan terhadap percikan air. Sensitivitas LDR (light dependent resistor) sangat baik pada saat mendapatkan cahaya dari lampu laser tepat mengenai pada permukaan bagian tengah.

Abstract

This study aims to evaluate the effect of fluid flow rate on the effectiveness of radiator performance by using nanofluid consisting of a mixture of raw water with nano silica (SiO2) particles. The research was initiated by testing the silica material morphologically using a Scanning Electron Microscope (SEM) with the aim of knowing its microstructure. Next, mix the silica nanoparticles (SiO2) with water using a ratio of 0.5%, processed using a magnetic stirrer for 8 hours and precipitated for 24 hours. After being separated from the sediment, the nanofluid was tested for performance using a series of cooling system performance test equipment. A series of test equipment consisting of a radiator, flowmeter, water pump, pipe installation, heater and reservoir tank. Research data collection was carried out at the inlet and outlet temperatures as well as the radiator wall. In this study, variations in fluid flow velocity of 2.5, 4.5, and 6 LPM were carried out. The results showed that the decrease in temperature with the use of a fluid flow rate of 6 LPM was able to dissipate heat well to the environment. The decrease in temperature that occurs is 2.5%. Meanwhile, the lowest average radiator effectiveness value at the lowest speed of 6 LPM is 0.905, the highest at a fluid flow rate of 4.5 is 0.930.

Abstract

This paper reports on community service activities carried out by the Politechnic Indonusa of Surakarta team foreign exchange reserves. Devotion is focused on the members of the cadet reef who have graduated from school that aim to provide knowledge and skill regarding repairs and maintenance of air conditioning (ac) cars. Through this program, it is expected that participants will be better prepared to open jobs in the service areas. This devotion begins with theoretical delivery, consisting of basic component materials and an automobile - conditioned mechanical system. Materials are delivered by methods of speech, discussion and question-and-answer. Participants are given understanding on how the components work, unloading the tides, checking damage, cleaning and trouble shooting on car ac units. The training was followed by 22 participants. The results of this training, being able to provide skill and understanding in the repair of car air conditioning, make it possible for participants to start their own businesses especially in the proper and proper areas of care and car ac repair.

Abstract

Dayu Village Gondangrejo Karanganyar has a leading tourist attraction in the form of the Dayu cluster early human museum. In accordance with the research and dedication that has been done, that still needs a touch to support existing tourism, namely from a culinary point of view, this aims to boost tourist interest in visiting Dayu village. Based on the initial identification, there were 2 main problems with the typical culinary of Dayu Village, namely problems in the production and marketing fields. From the initial identification above, the community service implementation team focused on increasing production capacity by providing production support equipment, CHSE socialization, food sanitation hygiene, and create a variety of flavors. while the marketing sector is given solutions for making labels/brands on packages, sealers on packages to make them look neat and creating promotional content on social media such as Instagram. Through the assistance provided, partners can further increase product productivity and increase sales of Balung Kethek as a typical tourist food in the area of the Dayu cluster early human museum.

Abstract

This research aims to determine the effect of composition on used tire powder composites, asphalt, and recycled plastic (rHDPE), on tensile stress. The composite is expected Can be used for fenders on cars. The composition variations in this study were 500 grams of used tire powder, and 100 grams of asphalt, with variations of rHDPE 20, 30, 40, 50, 60, 70, 80, 90, 100, 120, 200, 250, 300, 350, 400 grams. From the tensile test results, the lowest tensile stress was obtained 0.0233 N/mm2 is owned by a composite with a composition of 40-gram rHDPE. For tensile stress. The highest was a composite with a composition of 400-gram rHDPE with a tensile stress value of 0.855 N/ mm2. The tensile test results of factory-made car fenders have a tensile stress of 0.852 N/mm2. From this research, it can be concluded that composites with composition High rHDPE can be used for fenders.
