This research was carried out to identify hazards or dangers that could occur to workers, assess the risks, and finally be able to control the risk of danger using the HIRARC (Hazard Identification, Risk Assessment, and Risk Control) method. The research results show that in the risk assessment, there are 4 Low Risks, which means the risk is still acceptable, 5 Moderate Risks, which means the risk is still acceptable but needs additional risk control, and 3 high risks, which means the risk is not accepted, the risk needs to be reduced immediately. The proposed risk is to always use PPE that is appropriate to the job, and use work support tools such as supports and heavy forklifts. As well as always focusing on carrying out work, you must always be alert and responsive to areas or work environments that can pose risks and have good mutual coordination or communication between related workers.","PeriodicalId":17758,"journal":{"name":"Jurnal Serambi Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139319621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

XYZ is a manufacturing company that specializes in making food and soft drinks. According to the company, there have been no reports of incidents during the production process. However, based on empirical findings obtained from observations in the maintenance section, especially in the field of assembly work, many near misses or near misses occur during the implementation stage. Efforts that need to be made to overcome this are by identifying activities that are at risk of causing work accidents. In this research, work accidents were identified using the HIRA method, which then based on the results of the HIRA, improvements were then carried out based on priorities using the FMEA methodology. In the grinding machine assembly process, it is known that there are six work activities including material selection, grinding, welding, painting, assembly, and machine trial. The HIRA identification results show that there are 8 activities that have a medium risk of work accidents, for which FMEA analysis will be carried out. The results of the FMEA analysis show that the motor selection activity for the grinding drive has the highest RPN value so the control in the work is carried out using the help of a chain block, ensuring the chain block is in prime condition, using complete personal protective equipment, carrying out work according to SOP, and using chain block according to capacity.","PeriodicalId":17758,"journal":{"name":"Jurnal Serambi Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139320151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Menurut data dari Kementerian Lingkungan Hidup dan Kehutanan pada tahun 2021, total sampah yang dihasilkan mencapai sekitar 68,5 juta ton, dengan sekitar 11,6 juta ton atau sekitar 17% dari total tersebut adalah sampah plastik. Metode konvensional dalam pengolahan sampah plastik, seperti landfill dan open dumping, berdampak negatif terhadap lingkungan. Pembakaran plastik juga berkontribusi pada polusi udara. Daur ulang plastik hanya mengubahnya menjadi bentuk yang berbeda tanpa mengurangi jumlah sampah plastik secara keseluruhan. Oleh karena itu, diperlukan metode alternatif, dan salah satu metodenya adalah pirolisis. Pirolisis adalah proses yang mendegradasi material pada suhu antara 300°C dan 1000°C, menghasilkan gas yang dikondensasi dan dipecah menjadi minyak, meninggalkan arang. Berbagai faktor seperti komposisi material, suhu, waktu tinggal, dan ukuran bahan baku memengaruhi proses pirolisis. Penelitian ini bertujuan untuk mengembangkan teknologi pirolisis yang ramah lingkungan untuk mengubah sampah plastik menjadi bahan bakar alternatif berbasis minyak, mengevaluasi kualitas produk minyak, dan mengidentifikasi jenis sampah plastik yang cocok untuk pirolisis. Hasil penelitian menunjukkan bahwa pirolisis sampah plastik LDPE pada suhu 800°C menghasilkan minyak dengan sifat yang mendekati standar bensin dan solar Pertamina.","PeriodicalId":17758,"journal":{"name":"Jurnal Serambi Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139319929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bivariate analysis, on the other hand, is used to assess the association between two variables, with the chi-square test used to determine the link. Several adjustments are proposed to boost the efficacy of using the 5S Method. These enhancements may be made by conducting bivariate and univariate analyses to discover variables that impact the performance of the 5S Method implementation. This allows proposals for improvement to be developed and executed. To define the measuring scale, researchers utilized a Likert scale to disseminate the questionnaire. The signature value of 0.044 is less than the 0.05 significance threshold, hence the null hypothesis (H0) is accepted and the alternative hypothesis (Ha) is rejected. As a result, it is possible to infer that there is a considerable link between work supervision and 5S implementation in the PT XYZ Jetty department.
