In the engine reactor, used tires made from polystyrene, which is a long chain hydrocarbon, will experience a cracking process into shorter chain hydrocarbons. The steam from the heating will then be distilled into the reactor. This fuel production machine from used tire waste can be a solution for alternative sources of liquid fuel energy production, in this case sourced from waste tires which are increasingly worrying. For this reason, with this oil processing machine, it is hoped that it will reduce the impact caused by this used tire waste. and besides that it can make a useful fuel.","PeriodicalId":14205,"journal":{"name":"International Journal of Research in Vocational Studies (IJRVOCAS)","volume":"148 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88658920","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}

One type of textile waste processing is the production of hydrogen gas as a new and sustainable energy source. The water electrolysis method may be used to convert textile waste into hydrogen gas. In this study, hydrogen gas was produced from textile waste in two stages: electroplating waste treatment with an electrocoagulator and then processing textile waste into hydrogen gas using an oxyhydrogen reactor. Various catalysts, including NaOH, KOH, NaCl, and NaHCO3, were used in the process of converting textile waste into hydrogen gas, with a concentration of 0.5 M and an electrolysis period of 5 minutes. The addition of a catalyst is intended to identify the optimal concentration in the conversion of textile waste to hydrogen gas. The optimal KOH catalyst concentration for obtaining hydrogen gas was determined through study and analysis.","PeriodicalId":14205,"journal":{"name":"International Journal of Research in Vocational Studies (IJRVOCAS)","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85453555","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}

The 5P model is a five-stage paradigm that comprises preparation, promotion, process, purpose, and prosperity. Inside each of the five phases are 16 critical variables. To study the various parameters mentioned above, 202 employees from emerging and developed nations were recruited. We discovered that 152 applicants work in companies of the same level after completing 202 questionnaire 1 surveys under \"which level is your firm's standing”. These applicants will be invited to complete the second inquiry, titled \"Company Needs 5P to Go Forward.\" An independent T-test of 107 responses from 152 employees revealed that the greatest difference between the two groups was caused by the strength component in the promotion stage. Except for the inspection in the process stage, all of the 5P elements created a substantial difference between the two groups. Group 1 has a greater disparity between the two groups than Group 2. Activity in the process stage is the most important factor for group 1; strategy in the prospective stage is the most important factor for group 2. Employees of Group 1 are choosing time in preparation, strength in promotion, activity in process, product in purpose, and strategy in the prospective stage as the most important factors. Employees in Group 2 selected employee preparation, competition in promotion, activity in process, service in purpose, and strategy in the prospective stage as the most essential factors. The factors have a significant impact on the outcomes.

Seagrass beds can absorb carbon of 1.15 tons/ha, with a carbon content below the substrate of 0.88 tons/ha (76.3%), higher than the carbon above the substrate, which is only 0.27 tons/ha (23, 7%). Research on carbon absorption in seagrass is still relatively carried out, so it is necessary to research the potential for carbon absorption in seagrass types Enhalus acoroides and Thalassia hemprichii in Morotai waters. The research will be carried out from September to December 2021, starting with seagrass sampling in three sub-districts (South Morotai, East Morotai, and South West Morotai Districts). The types of seagrass used were Enhalus acoroides and Thalassia hemprichii. Biomass sample analysis was carried out at the Basic Laboratory of the Faculty of Fisheries and Marine Sciences, Pacific Morotai University. Carbon analysis on seagrass was carried out at the Chemical Oceanography Laboratory of the Faculty of Marine and Fisheries Sciences, Hasanudin University Makassar. The seagrass sampling method used the quadratic transect method and sample analysis using the method Loss On Ignition (LOI). The results showed that Thalassia hemprichii has the highest carbon content in the roots, with a value of 38.94 gC/m2 to 49.48 gC/m2. In contrast, Enhalus acoroides has the highest carbon content in the roots with a carbon value of 30.77 gC/m2 to 37.86 gC/m2.","PeriodicalId":14205,"journal":{"name":"International Journal of Research in Vocational Studies (IJRVOCAS)","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85173689","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}
