Abstract

Heat wasted due to radiation from the flame around the LPG stovecan lower stove efficiency. The wasted heat would be exploited by using a finned heat reflector . The working principle of this tool is to capture the wasted heat  and reflect to the load so that it becomes useful energy . Preliminary data indicate that areflector without fins can increase stove efficiency., The objective of this research isto determine the performace finned heat reflectorin increasing LPG stove  efficiency. A piece of stainless steel plate as a truncated cone-shaped finned experimental model was used as a reflector. The efficiency test is done through  boiling water test. The number of fin of the the same dimensions were varied, starting from one-line to three-line fins. The performance of the stoves using reflectorwith fins were compared with that of stove using reflector without finsand with that of stove without reflectot. Based on test results, it is found that the use of finned reflectors is able to increase the efficiency of LPG stoves. The highest efficiency is obtained on the use of reflectors with three rows of fins, which amounted to 44.09%. The magnitude of the increase is compared to without using a reflector at 5.22%, while compared with the reflector without fins for 5.01%. Based on the test of temperature distribution is obtained also that the use of reflector finned heat radiation can increase the area of complete combustion.

Abstract

The defective combustion process is one of the causes of low efficiency in LPG stoves. Increasing the efficiency in LPG stoves by optimizing the combustion has high possibility to do. Practical effort that can be done is adding the element embers. This tool is a woven wire nikelin that are arranged in layers and if it is heated, it will be incandescent, forming high temperature embers. Generated embers will be able to burn fuel vapor perfectly around the wire, so it will broaden the mature fire area. The test is done by using LPG stoves which is provided by finned heat radiation reflector. The efficiency test is done by conducting the boiling water test. The number of element embers layers are varied, from one to four layers. The performance of element embers use is compared with LPG stoves without element embers use. In this study, temperature distribution for each treatment is tested. It is obtained that the use of element embers without reflector can improve the efficiency until 8.23%. The highest efficiency occurred in one of layer element embers use, as much as 61.7%. But, the increase of element embers in finned heat radiation reflector decreased the efficiency. It was because the mounting pattern of element embers bothered the function of the reflector, so the heat reflection from the reflector was stunted and stuck between the reflector and the mounting pattern. Therefore, the heat energy of the reflection from the reflector cannot be moved to combustion area. The result of temperature distribution test also showed that the element embers use could broaden the mature fire area.

Abstract

Tuna Daksa is a term for individuals who have lost or incomplete body parts that can be seen with the naked eye. One solution to help people with physical disabilities in carrying out daily activities in the field of transportation. Modification of motorized vehicles often lacks safety, especially when used on curvy roads due to lack of balance, so that it is overcome by modifying motorized vehicles using the one-wheel pull method. This method is used to adjust the balance of wheel rotation when turning a corner, and is equipped with parts that can support comfort in its use. The main parameter in this research is the analysis of the spindles and the components of the tools used. The material used to design the axle with bending load only is JIS E4502 class 4 carbon steel qwb = 60 kg/mm and its elongation limit is 30 kg/mm. The feasibility of the design of the modification of the tool is based on the results of research from the calculation that the diameter of the calculation results is above 17 mm, very safe to use and more than 1 mm with the previous diameter of 16 mm.

Abstract

AbstrakPermasalahan kesehatan mental pada remaja menjadi salah satu isu yang perlu mendapat perhatian, terutama di lingkungan sekolah. Berdasarkan hasil observasi dan koordinasi dengan pihak SMPN 2 Poncol, belum pernah dilakukan skrining kesehatan mental secara rutin sehingga kondisi psikologis siswa belum teridentifikasi secara optimal. Selain itu, pengetahuan siswa mengenai kesehatan mental dan cara mengelola stres masih terbatas. Kondisi tersebut berpotensi menyebabkan masalah psikologis tidak terdeteksi sejak dini dan berdampak pada proses belajar maupun perkembangan sosial siswa. Kegiatan pengabdian kepada masyarakat ini bertujuan mengidentifikasi kondisi kesehatan mental siswa SMPN 2 Poncol melalui skrining awal menggunakan Self Reporting Questionnaire (SRQ) serta meningkatkan pengetahuan dan kesadaran siswa tentang pentingnya menjaga kesehatan mental. Metode pelaksanaan kegiatan dilakukan secara sistematis melalui empat tahap, yaitu persiapan dan koordinasi dengan pihak sekolah, pelaksanaan skrining menggunakan instrumen SRQ, wawancara lanjutan pada siswa yang menunjukkan indikasi gangguan psikologis, serta edukasi kesehatan mental mengenai pengelolaan stres, kecemasan, dan pentingnya dukungan sosial. Kegiatan dilaksanakan pada 34 siswa SMPN 2 Poncol dari total 37 siswa yang terdaftar. Hasil skrining menunjukkan bahwa 17 siswa (50%) terindikasi mengalami gejala psikologis, sedangkan 17 siswa lainnya (50%) tidak menunjukkan gejala psikologis. Berdasarkan jenis kelamin, gejala psikologis ditemukan pada 6 siswa laki-laki (30%) dan 11 siswa perempuan (78,6%). Hasil wawancara menunjukkan bahwa tekanan akademik, hubungan dengan teman sebaya, dan kondisi keluarga menjadi beberapa faktor yang memengaruhi kondisi psikologis siswa. Kegiatan ini berhasil memberikan gambaran awal mengenai kondisi kesehatan mental siswa sekaligus meningkatkan kesadaran mereka terhadap pentingnya menjaga kesehatan jiwa. Temuan ini menunjukkan perlunya skrining kesehatan mental secara berkala serta kolaborasi antara sekolah dan tenaga kesehatan dalam upaya promotif dan preventif untuk mendukung kesehatan mental siswa. Kata kunci: skrining; kesehatan_mental; self_reporting_questionnaire. Abstract Mental health issues among adolescents are a pressing issue, particularly within the school environment. Based on observations and coordination with SMPN 2 Poncol, routine mental health screenings have not been conducted, resulting in inadequate identification of students' psychological well-being. Furthermore, students' knowledge of mental health and stress management remains limited. This situation can potentially lead to early undetected psychological problems, impacting their learning and social development.This activity aims to conduct initial mental health screenings for students at SMPN 2 Poncol. This community service activity aims to identify students' mental health conditions through initial screening using the Self-Reporting Questionnaire (SRQ) and increase students' knowledge about the importance of maintaining mental health. The activity was implemented systematically through four stages: preparation and coordination with the school, screening using the SRQ instrument, follow-up interviews with students who exhibited psychological disorders, and mental health education on stress management and anxiety management, as well as the importance of social support. The activity was conducted with 34 of the 37 registered students at SMPN 2 Poncol. The screening results showed that 17 students (50%) were indicated to be experiencing psychological symptoms, while the other 17 students (50%) did not show any psychological symptoms. Based on gender, psychological symptoms were found in 6 male students (30%) and 11 female students (78.6%). Interview results indicated that academic pressure, peer relationships, and family conditions were some of the factors that influenced students' psychological conditions. This activity succeeded in providing an initial overview of students' mental health conditions while raising their awareness of the importance of maintaining mental health. These findings demonstrate the need for regular mental health screenings and collaboration between schools and health professionals in promotive and preventive efforts to support students' mental health. Keywords: screening; mental health; SRQ.
