The combine harvester in Yogyakarta Province Special Region has a small size because it is used to harvest rice in a narrow area. The purpose of this study is to determine which parts of the mini combine harvester machine are not ergonomic and need to be improved so that the operator can work comfortably and safely. The types of mini combine harvester machines investigated in this study are QUICK H140R, TANIKAYA Ironbee HT12, and JAP001. Results showed that, for the three combine harvester machines, there was a mismatch in the physical size of the engine and the anthropometry of the operator. The main problems of the mini combine harvester machine are less ergonomic seat, inappropriate placement of the control table, hand activity in the maximum area, narrow workspace for leg movements, and less supportive footstep for the operator to work while standing. This information is expected to be utilized by Indonesian mini combine harvester machine designers so that the new design of combine harvester machines will be ergonomic, safe, and comfortable.

There are five types of cotton waste produced by the Spinning Division of PT. Sri Rejeki Isman Tbk: dropping, flat strip recyclean, flat strip c, air waste, and fan open end, which has a smaller trash content. The research objective is to determine the potential utilization of cotton waste as the basic material for white oyster mushroom planting media, to determine effect of planting media formula on the growth of white oyster mushroom, and to determine the best formula for white oyster mushroom planting media. Utilization of cotton waste are examined by 5 formulas: control with 100% sengon wood powder + 200 gram bran + 10 gram lime (S0), 50% dropping + 50% sengon wood powder + 200 gram bran + 10 gram lime (S1a), 75% dropping + 25% sengon wood powder + 200 gram bran + 10 gram lime (S1b), 50% fan open end + 50% sengon wood powder + 200 gram bran + 10 gram lime (S2a) and 75% fan open end + 25% sengon wood powder + 200 gram bran + 10 gram lime (S2b). This study uses a 5x3 Completely Randomized Design (CRD 5x3) and is then analyzed using the One Way Anova test and the Least Significant Difference (LSD) test. The best formula was chosen for planting media based on the highest score in Zero-One Integer Programming. Parameters observed on the planting media are changes in the content of cellulose and lignin, while on the fungal growth is the form of mycelium fulfillment time; the number of fruit bodies; hood width; wet weight, and stem length. This study indicates that cotton waste can be used as a base material for white oyster mushroom planting media, where the best formula is S2b. During fungal growth, in the planting media with formula S2b, cellulose degradation occurs from 66.7% to 60.8%, and lignin degradation occurs from 10.5% to 6.6%. In addition to the media, formula S2b produces mushrooms with growth characteristics including mycelium fulfillment time of 28.33±1.53 days, the number of fruit bodies 17.67±8.96, hood width 5.76±0.87 cm, wet weight 143.33±26.27 grams, and stalk length 4.52±0.55 cm.

Manual material handling activities are still widely practiced in various industries, including supermarkets. Various products in supermarkets are moved with hand truck aids. This tool is used to ease of workers to avoid the risk of MSDs (musculoskeletal disorders) and LBP (low back pain). Workers' who concerns about work ergonomics, materials handling tools and their working environments can reduce the risk of MSDs and LBPs. In this paper we will examine how much the workers care about themselves, their tools, environment and their relation to work physiology of workers.Workers' concerns were identified using a Likert scale questionnaire with 5 scale of interest. Self-awareness is linked to an understanding of ergonomics, to hand tools used everyday and to the work environment. Occupational physiology is reflected in the pain experienced by workers as job impacts identified using Nordic Body Map (NBM), and work posture using OWAS (Ovako Working Posture Analysis System).The material handling worker assigned to move the product from supplier vehicle to warehouse or to showroom by hand truck. The survey results that the worker's concerned not so high on his ergonomics. The body map shows that before working the worker felt pain all over his body and got more pain after work. Worker's work posture varies substantially in category 1-2 which means that in this musculoskeletal system the work attitude results in significant tension influences requiring future improvement.

Rice harvesting is a high ergonomic risk due to the working position, an awkward posture, and the repetition activity. Rice harvesting causes body pain in the part of low back, hand, and wrist. This study aims to (1) identify the characteristics of non-mechanical rice harvesting; (2) determine the working posture of rice harvesters using the Ovako Working Assessment System (OWAS) method, Quick Exposure Checklist (QEC), Rapid Entire Body Assessment (REBA), Postural Ergonomics Risk Assessment (PERA); and (3) determine the best method to assess harvesters work posture. An observation was conducted to nine of healthy workers in Bantul and Sleman districts, Daerah Istimewa Yogyakarta (DIY) province. The questionnaire was set to collect respondent demographics data. Data for harvester body posture (neck, trunk, leg, wrist, lifting load, shoulder) repetition, duration and force were collected by observation in the field. A sickle was used to cut rice straw, while a manual gepyok and mobile hand thresher was used to threshing rice panicles. Four methods were applied to assess the work posture, i.e., OWAS, QEC, REBA, PERA methods. Based on observation, five workstations were identified: (1) cutting rice straw, (2) transporting rice straw, (3) threshing of panicles, (4) sorting, and (5) packaging and transporting. REBA and PERA showed a similar trend of the ergonomic risk, high to low risk took place in workstation transporting rice straw, packaging and transporting, cutting, and threshing. The assessment of work posture that is most suitable for non-mechanical harvesting methods was the REBA method with an accuracy of 92.9%.

It is essential to manage waste in an integrated manner, beginning at the domestic and village levels. In fact, there are still a significant number of residents who throw trash carelessly. Jurangjero village, a village in Klaten Regency, Central Java, is an example of a village that does not adequately manage its waste. In addition, the village has agricultural waste issues that require optimal utilization, including rice straw. This community service program aims to increase public awareness of organic and inorganic domestic waste management and agricultural waste management so that they can be applied appropriately to the concept of the green village. The program’s methods included field observations, waste management outreach, and training. The training included the creation of organic fertilizers, eco-bricks, plastic waste containers, and straw paper. Farmer groups and farmer women’s groups have gained an understanding of the management of domestic organic waste into organic fertilizer and compost as a result of the outreach and training activities. Karangtaruna has also gained an understanding of inorganic waste management by applying the recycling concept, which entails transforming plastic refuse into plastic pots and ecobricks. They have also grasped the production of economically valuable art paper from rice stalks. The descriptive analysis revealed that the average pre-test and posttest scores were 55.58 and 76.67, respectively. Based on these findings, it can be concluded that this community service program has increased residents’ knowledge of managing domestic and agricultural waste to create valuable products. The support of the village administration is required for sustainable waste management and the continuation of empowerment initiatives.
