The sluggish respirate rate increases the shelf life of fruits. The after-effects of MAS treatment have been investigated from the installation design until gas composition in the storage, however the investigation about the correlation between the treatment level and the fruits characteristic is still limited on the flavor, color, and weight. Therefore, the research goal is to investigate the MAS treatment result based on skin thickness. A series of experiments with full factorial arrangement and three replications, is set in a storage installation.  Skin thickness is classified in to three levels, which are thin, medium, and thick. Each level is represented respectively by orange, banana, and watermelon. Both fruits with and without MAS treatment are quantified by measuring glucose level, to make a comparation.  The outcome of the research from measurement shows fruits which undergo MAS treatment have lower glucose levels than the ones without the treatment, but the weight remains the same.  The mass transfer coefficient with the thickness became a baseline for sudden exchange in the storage.","PeriodicalId":509378,"journal":{"name":"Journal of Applied Engineering and Technological Science (JAETS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141379117","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 problem faced in developing small and medium industries is the diverse and varied nature of these enterprises, both in terms of quantity and scope, which leads to unfocused management of potential commodities and types of businesses. A technopark is one of the alternative strategies to develop small and medium industries based on superior commodities. Determining superior commodities is an initial step in developing small and medium industries through technoparks. The purpose of this study is to identify the superior commodities that will be developed in small and medium industries through technoparks in Kampar Regency, Riau Province. Data collection techniques were conducted through literature studies and expert interviews, using purposive sampling. The determination of commodities was done through LQ and SSA. The data used were horticultural crop production from 2017-2021. The study results indicate that pineapples are a superior commodity due to their extensive distribution in five sub-districts, boasting the largest harvest areas, abundant raw materials, and regional potential with LQ >1 and SSA > 0.

Analysis of regional geotechnical and topographic characteristics, land use modeling, and review of the impact of human activities on slope stability. The analysis method uses the Plaxis 2D program to obtain slope safety factors in the Kubang Tangah residential area, Sawahlunto. The research results show that residential areas in Kubang Tangah have a high level of landslide risk, influenced by slope, soil type, and changes in land use. Varying rainfall levels significantly contribute to the potential for landslide hazard.

The government's determination of the Tri Dharma of Higher Education consists of education and teaching, research, and community service. These activities must be implemented in the academic information system of every university in Indonesia. Appropriate and fast academic services depend on information technology and adequate and trained human resources (HR). Factors that influence information system security determine the stability of application services. The ISO/IEC 27001:2005 standard is an international benchmark for measuring the level of maturity and security risks of an application. Risk assessment in standard operating procedures in organizations can use the ISO/IEC 27001 standard. This research aims to determine the current level of Academic Information System (AIS) service by measuring maturity and security risks. Three clauses measure the maturity level of information security controls with the ISO 27001 System Security Engineering-Capability Maturity Model (SSE-CMM). These research respondents are educational work units at the Science and Technology Faculty in UIN Syarif Hidayatullah Jakarta. This research method uses quantitative research methods. This research results show the maturity level of information security in the academic information system based on three clauses as the embodiment of the stability of the academic administration activities services at the Science and Technology Faculty. The measurement results reveal that the average score of information security controls on AIS is 3.51, which means good or average standard processing has been carried out following procedures.","PeriodicalId":509378,"journal":{"name":"Journal of Applied Engineering and Technological Science (JAETS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141380712","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}

La(1-x)Sr(x)MnO3 is one of the best candidates for hyperthermia due to higher magnetic at ambient temperature and their Curie temperature easily adjusted. This research synthesized La(1-x)Sr(x)MnO3 using the ball milling technique. Several heat treatments were also conducted after ball milling processing. Various investigations, including SEM-EDS, XRD, DSC, and VSM, were conducted. LaMnO3 has a hexagonal structure, which has the space group R -3 c. From the diffraction pattern seen in LaMnO3 and La0.9Sr0.1MnO3 seen at angles 32.376 and 32.706, it looks separate like the database diffraction pattern. In La0.9Sr0.1MnO3, these two peaks are seen to be increasingly separated. In contrast to the diffraction patterns of La0.7Sr0.3MnO3 and La0.5Sr0.5MnO3 at an angle of 32.376, there is a decrease in intensity. The specific heat capacity of the alloy with Sr substitution of 0.3 has a greater value than that without substitution and the lowest occurs in the alloy with Sr substitution of 0.1. The magnetization value for Sr substitution is 0.3 higher than for other alloys.","PeriodicalId":509378,"journal":{"name":"Journal of Applied Engineering and Technological Science (JAETS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141381241","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}
