This will increase global warming and the occurrence of an energy crisis. Referring to this, a cooling system that is more energy-efficient and environmentally friendly is needed. One alternative is to use natural materials as adsorbents in adsorption air conditioning. In this system, changes in humidity levels occur due to the process of absorption of air moisture in each test material in the packed bed. The purpose of this research is to determine the regeneration characteristics of natural materials and activated carbon, as well as their performance against moisture. The characteristics tested also include contact angle test and proximate test. In addition to the type of material, mass variations of 200gr, 400gr, and 600gr are also carried out as well as variations in the combination between materials. The results obtained from the regeneration test 9 times, natural ingredients affect air conditioning. The larger the mass tested, the greater its ability to reduce humidity. In another sense, 600gr activated carbon provides the most optimal performance among other natural materials, both in mass variations and combined variations.","PeriodicalId":19046,"journal":{"name":"Natural Sciences Engineering and Technology Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77902386","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 library is one of the most important places in any academic institution and remains the primary source of information for students, teachers, and many others. The researcher aims to suggest an option for the state university and colleges in the Province of Sulu on the technological advancement in the managing library. The breakthrough of technologies can help the library in various ways. Libraries need to adopt new technology that will allow them to operate and function efficiently and effectively, increasing their productivity and improving their user services without adding personnel. The main objective is to show that an automated library system using the latest technology is more beneficial. The present scenario demands an updated technology for faster, affordable, and user-friendly in providing various library services. Fortunately, new technologies have developed Barcode, Digital libraries, Quick Response codes, and RFID systems. Consequently, applying these technologies provides an end-to-end solution for easy library operation, such as borrowing and returning books, finding and locating books, and maintaining book records. The need to develop and enhance library services to meet users' demands is necessary.","PeriodicalId":19046,"journal":{"name":"Natural Sciences Engineering and Technology Journal","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72689691","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}

Network infrastructures are designed not just to provide backbone connectivity but must ensure reliability in accordance with the security measures and standards accepted in the field of information and communications technology. Management of the resources deployed in the implementation of the infrastructure should be observed in order to serve its purpose, and that is to provide a high performing IT environment that promotes secured and uninterruptible communication line to the stakeholders of the organization leaving each and every one of them satisfied and protected while connected in the network. This paper was anchored on the view that management of network infrastructure is important in every organization as its communication backbone. Likewise, this provides a concise discussion and a literature review about the significance of managing the network infrastructure in an organization. Having a quality IT infrastructure ensures reliability on the part of information transmission and security within the scope of the organization’s internal operations. Regardless of the organization’s nature, administrators or managers must invest in building a standardized infrastructure that is scalable, credible, and cost-effective.

Scabies is often neglected because it is not life- threatening so the priority of treatment is low, but actually chronic and severe scabies can cause dangerous complications. WHO noted that approximately 130 million population in the world experienced scabies in 2018. While in Aceh in 2017, approximately 40.78% of pesantren adolescents suffered from scabies. This study aims to determine the relationship between education, knowledge and behavior related to the incidence of scabies in Syamtalira Bayu District, North Aceh Regency.
