Abstract

The agricultural sector is the backbone of the national economy, which is still dominated by manual work practices with high ergonomic risks. This impacts health, workplace accidents, and occupational diseases. This study aims to identify, analyze, and evaluate ergonomic risk factors in work activities in the agricultural sector, particularly in the process of preparing rice fields. This process consists of manual hoeing, manual land leveling, and land cultivation with a tractor. The study location is in Kolelet Village, Picung District, Pandeglang Regency, which is one of the rice granaries in Banten Province. The results of the Nordic Body Map (NBM) questionnaire showed that the most complaints were found in manual land leveling workers, followed by manual hoeing workers, and the least in tractor operators. The body parts most frequently experiencing musculoskeletal disorders (MSDs) were the shoulders, back, waist, arms, thighs, and calves. The results of the Rapid Upper Limb Assessment (REBA) analysis show that the work posture value for manual hoeing is 10 (High Risk), for manual land leveling the REBA value is 12 (Very High Risk), while for tractor operator work, the REBA value is 5 (Medium Risk). From the OWAS analysis, all three jobs are in the Red category, with the main factors being the workload and duration. For work environment conditions, 12:00 to 14:00 is the most dangerous hour with temperature, humidity in the danger category, and the UV index categorized as very high. The noise factor from the tractor sound ranges from 81-89 dB, still in safe conditions, with a work duration of between 2-6 hours a day.

Abstract

Office workers are at high risk of developing musculoskeletal disorders due to prolonged static sitting positions. This study was conducted at the Indonesia Exim bank to explore the relationship between office chair design particularly the presence of lumbar support and musculoskeletal complaints. The methods used included questionnaires, as well as assessments using RULA and the Nordic Body Map, involving 32 participants. The results indicated that the lower back and waist were the most frequently reported areas of discomfort. Although the chairs used were ergonomically designed, the lumbar support was not optimal. By designing a lumbar support based on anthropometric data, a significant improvement in posture comfort was observed.

Abstract

The knowledge and skills of product design and manufacture are still very minimal experienced by most students of the 7 Tangerang Banten State Vocational High School (SMKN). This is because all students come from public schools. The SMKN 7 curriculum only emphasizes increasing knowledge and insight into attitudes and noble character. The practice given is about dancing skills, making worship facilities and skills in chanting holy songs and similar skills. Discussions with students and teachers produced data on students' needs to increase knowledge, insight and skills, especially designing and manufacturing products through basic welding techniques. Welding skills are needed as a provision for entrepreneurship in the field of welding. The implementation of PKM is carried out in 2 stages, namely the debriefing stage and the practical stage in the welding workshop. The debriefing produces various concepts of Minimalist Ergonomic Chairs according to the specified criteria. The practice is carried out in groups to realize the existing designs. Practical activities provide experience measuring materials, cutting, sanding, grinding, rolling, welding, and painting and teamwork. The output of the training resulted in a concept and prototype design of a Minimalist Ergonomic Chair Made from Nako Iron. Debriefing and practice can increase market research knowledge by 80%, increase 70% in understanding human factors and increase 90% in understanding the stages of product design. Field practice increases experience working in groups by 50% and the ability to use welding shop equipment increases by 50%. All participants were satisfied with the instructor's guide and training materials. In general, skills training activities are called successful. Pengetahuan dan keterampilan perancangan dan pembuatan produk masih sangat minim dialami sebagian besar siswa Sekolah Menengah Kejuruan Negri (SMKN) 7 Tangerang Banten. Hal ini karena seluruh siswa berasal dari sekolah umum. Kurikulum SMKN 7 hanya menekankan pada peningkatan ilmu dan wawasan sikap dan budi pekerti luhur. Praktik yang diberikan seputar keterampilan menari, membuat sarana ibadah dan keterampilan melantunkan kidung suci dan keterampilan sejenis. Diskusi dengan siswa dan guru menghasilkan data kebutuhan siswa untuk peningkatan ilmu, wawasan dan keterampilan khususnya perancangan dan pembuatan produk melalui teknik pengelasan dasar. Keterampilan mengelas diperlukan sebagai bekal berwirausaha bidang pengelasan. Pelaksanaa PKM dilakukan 2 tahap yaitu tahap pembekalan dan tahap praktik di bengkel las. Pembekalan menghasilkan berbagai konsep Kursi Ergonomis Minimalis sesuai kriteria yang ditentukan. Praktik dilaksanakan secara berkelompok mewujudkan disain yang telah ada. Kegiatan praktik memberikan pengalaman mengukur bahan, memotong, mengampelas, menggerinda, mengerol, mengelas, dan mengecat dan kerja tim. Luaran pelatihan menghasilkan konsep dan Rancangan protptipe Kursi Ergonomis Minimalis Berbahan Besi Nako. Pembekalan dan praktik mampu menambah pengetahuan riset pasar sebesar 80%, peningkatan 70% pada pemahaman faktor manusia dan peningkatan 90% pada pemahaman tahapan perancangan produk. Praktik lapangan menambah pengalaman bekerja berkelompok sebesar 50% dan kemampuan menggunakan peralatan bengkel las meningkat sebesar 50%. Semua peserta puas dengan panduan instruktur dan materi pelatihan. Secara umum kegiatan pelatihan keterampilan disebut berhasil.

Abstract

SMKN 12 Tangerang is a school that offers learning programs which usually cover fields such as engineering, business, information technology, tourism, and others. Each specialty program has a specific curriculum to provide the theoretical knowledge and practical skills required in that field. Based on the results of interviews and curriculum reviews, it revealed deficiencies in product design material and welding practices at SMKN 12, besides that the demand for welding products in Tangerang and its surroundings has also increased quite a bit due to residential and business developments. PKM implementation is carried out using two methods, namely the method of providing theory through the zoom meeting application and carrying out practice directly in the welding workshop. When making a product, it is also necessary to pay attention to the aesthetics of the product to be made, this is because an aesthetic product frame refers to the design of the framework or basic structure of a product that not only functions optimally but also provides high aesthetic value. After the PKM was completed, several advances were obtained, namely provision and practice were able to increase understanding of the importance of market research by 90%, 90% increase in understanding the importance of human factors and 90% increase in understanding of product design stages, then field practice was able to increase experience working in groups was 81.25% and the ability to use welding workshop equipment increased by 100%. ABSTRAK SMKN 12 Tangerang merupakan sekolah yang menawarkan program-program pembelajaran yang biasanya meliputi bidang-bidang seperti teknik, bisnis, teknologi informasi, pariwisata, dan lainnya.
