Pemulung merupakan suatu pekerjaan dengan mencari sampah bekas, baik kardus ataupun botol plastik yang masih dapat didaur ulang, sehingga dapat dijual ke agen. Gerobak yang digunakan pemulung untuk mengangkut sampah selama ini memiliki beberapa keterbatasan, mengakibatkan pengguna sering mengeluh kesakitan pada punggung, pinggang, tangan dan telapak tangan karena beban yang diangkut pada gerobak sampah mencapai berat lebih dari 250 Kg. Oleh sebab itu, perlu dilakukan perbaikan desain gerobak sampah yang aman, dan nyaman bagi penggunanya. Program ini merancang ulang gerobak pemulung dengan pendekatan ergonomis pada dimensi tubuh pengguna. hasil rancangan Gerobak pemulung tersebut dapat menurunkan keluhan Nordic Body Map pemulung dari rata-rata sebesar 86,5% menjadi 40,2 %. Dimensi rancangan gerobak pemulung yang terbuat dari besi siku ini dengan tinggi tanpa roda 70 cm, lebar 52 cm dan panjang 100 cm. Sedangkan jarak pegangan, untuk dorongan maupun tarikan, dengan batas tepi gerobak dibuat adjustable agar dapat digunakan secara bolak balik, baik didorong maupun ditarik, sehingga pemulung dapat menggunakannya dengan nyaman dan aman. Sedangkan untuk pintu gerobak dirancang dua bagian yaitu satu di depan dan satu di bagian samping untuk memudahkan pembongkaran sampah.

Mapping land surface water bodies from satellite images is superior to conventional in situ measurements. With the mission of long-term and high-frequency water quality monitoring, the launch of the Ocean and Land Colour Instrument (OLCI) onboard Sentinel-3A and Sentinel-3B provides the best possible approach for near real-time land surface water body mapping. Sentinel-3 OLCI contains 21 bands ranging from visible to near-infrared, but the spatial resolution is limited to 300 m, which may include lots of mixed pixels around the boundaries. Sub-pixel mapping (SPM) provides a good solution for the mixed pixel problem in water body mapping. In this paper, an unsupervised sub-pixel water body mapping (USWBM) method was proposed particularly for the Sentinel-3 OLCI image, and it aims to produce a finer spatial resolution (e.g., 30 m) water body map from the multispectral image. Instead of using the fraction maps of water/non-water or multispectral images combined with endmembers of water/non-water classes as input, USWBM directly uses the spectral water index images of the Normalized Difference Water Index (NDWI) extracted from the Sentinel-3 OLCI image as input and produces a water body map at the target finer spatial resolution. Without the collection of endmembers, USWBM accomplished the unsupervised process by developing a multi-scale spatial dependence based on an unsupervised sub-pixel Fuzzy C-means (FCM) clustering algorithm. In both validations in the Tibet Plate lake and Poyang lake, USWBM produced more accurate water body maps than the other pixel and sub-pixel based water body mapping methods. The proposed USWBM, therefore, has great potential to support near real-time sub-pixel water body mapping with the Sentinel-3 OLCI image.

<p><em>Jaya Launch Pad is a company engaged in educational services. It is undeniable that service sector companies such as Jaya Launch Pad also have a workforce whose work posture may be less ergonomic, which can lead to musculoskeletal disorders. Musculoskeletal disorders can be experienced by people of all ages. Therefore, this study focuses on work posture. This research occurred because of complaints experienced by staff. The number of samples used in this study was 1 person. This was influenced by the Covid-19 pandemic situation so that there was only 1 staff when the observation was made. The research method used was the nordic body map (NBM) to determine which parts of the body are experiencing complaints, and the rapid office strain assessment (ROSA) to measure the risk of injury due to the posture of sitting at a computer for 8 hours. The result is that the complaint assessment using the NBM questionnaire has a score of 52 (needs improvement at a later date) with 4 categories of severe pain, namely back, waist, buttocks, and buttocks. Meanwhile, the score from the ROSA table is 6 which means it is risky / dangerous so that it needs improvement. Therefore, a proposed condition is given in the form of a replacement of work facilities in the form of a work chair with adjustable height and adjustable armrests. This improvement is assumed to be able to reduce the level of staff complaints, and the calculation result of the rapid office strain assessment (ROSA) is 4 which means no risk so that this improvement is accepted and can solve the work posture problem of staff at Jaya Launch Pad.</em></p><p><em> </em></p><p> </p>

Design Ideas

The case in the metal casting process is when the metal is melted and then poured into a liquid metal reservoir and then poured into a pouring tool and then poured into a mold. In the process of pouring into the mold is still using manual equipment, namely by using wood which ends have a container such as a bucket ( bucket)) made of a mixture of white cement, brick fire sand and clay and the metal liquid pouring tool has a length of 1.5 cm, a weight of 5 kg with a diameter of 15 cm and a height of a container for liquid metal 20 cm does not include the load. If the pouring device filling with liquid metal, then the weight reaches ± 20 kg, with a weight of ± 20 kg the worker must pour the liquid continuously into the mold and at least each worker must go back and forth 6 times pouring metal liquid into a mold in a single combustion process. Based on the nordic body map questionnaire data as many as 8 workers felt pain in the shoulder and arm because the burden was born, resulting in workers often feel pain in the muscles of the arms and back. Because the wooden handle used to pour metal liquid is too slippery (exposed to sweat), so there is a need for improvement in activities. From the results of the above observations, it is necessary to design ideas for new work facilities. It expects to affect the improvements related to the position of the hand in the process of pouring liquid into the mold. Then the design idea needs to be done in the form of a casting tool that has been modified and can be used according to user needs and can be said to be ergonomic, safe, and comfortable. The method used in designing castings is quality function deployment and anthropometric techniques.
