The research used the theory of satisfaction. Kotler (2014) points out that there are two theories of satisfaction: theory of performance expectation and theory of cognitive inappropriateness. Theory of performance expectation states that consumer satisfaction is the function of consumers’ expectation of the result. If the result is in accordance with what has been expected, consumers will be satisfied, if it exceeds what has been expected, they will be more satisfied, but if it is not in accordance with what has been expected, they will be dissatisfied. The population was 5,994 members of the library, and 98 of them were used as the samples, taken by using Slovin formula. The data were gathered by using questionnaires and conducting documentation and observation. The result of the research showed that the factors of communication strategy and prime service had positive and significant influence on library members’ satisfaction which indicated that the better the communication strategy and the prime service, the higher the library members’ level of satisfaction.","PeriodicalId":14205,"journal":{"name":"International Journal of Research in Vocational Studies (IJRVOCAS)","volume":"77 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140477203","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}

This furniture market opportunity will continue to grow in the future but must be supported by production factors, namely the provision of quality raw materials, capital and skilled labor. However, this industry is not free from problems such as the quality of raw materials. Wood raw materials in Indonesia are abundant but there is no special treatment to maintain its quality, so the quality of production is hampered. Good wood raw materials are raw materials that avoid damage and weathering. To maintain this quality, the ideal requirement for room temperature for storage is 18oC and room humidity 65%. Changes in temperature and humidity in the storage warehouse always follow changes in temperature and humidity around it. For this reason, further studies are needed on the temperature and humidity monitoring system in the storage warehouse and if there are significant changes, a dehumidifier device is used to keep the temperature and humidity in a room stable.  ","PeriodicalId":14205,"journal":{"name":"International Journal of Research in Vocational Studies (IJRVOCAS)","volume":"528 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140476814","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}

Red bricks are made from clay and can be mixed using additives. The use of clay has the most composition in the red brick mixture. Adding addictive materials is an effort that many researchers have made to improve the quality of red bricks. In this study, researchers were interested in using carrageenan as a mixture of red bricks. The research was carried out experimentally in the laboratory by making brick samples measuring 5 cm x 5 cm x 5 cm with various mixtures of BMC (control), BMK5 with the addition of 5% carrageenan, BMK10 with the addition of 10% carrageenan, and BMK15 with the addition of 15% carrageenan with drying temperature 50°C, 100°C, and 150°C for 24 hours.Research data was obtained through an experimental process of testing the compressive strength of red bricks using a compression test equipment. The data obtained was processed to obtain the compressive strength value of the red brick. The results showed that addition of 5% of the carrageenan mixture had an effect on the compressive strength of the red brick. Addition of 5% carrageenan contributed to the increase in the compressive strength of the red brick. There was a decrease in the compressive strength of the red brick in the sample with the percentage of addition carrageenan by 10% and 15 %. The ideal drying temperature for a mixture of red bricks with carrageenan is at 50℃ for 24 hours.","PeriodicalId":14205,"journal":{"name":"International Journal of Research in Vocational Studies (IJRVOCAS)","volume":"595 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140477029","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}

{"title":"Study of Residual Soil Permeability Coefficient Post Addition of Coal Fly Ash","authors":"Rasdinanta Tarigan, Parman, Muhammad Ari Subhan Harahap","doi":"10.53893/ijrvocas.v3i4.103","DOIUrl":"https://doi.org/10.53893/ijrvocas.v3i4.103","url":null,"abstract":"Residual soil is soil that is often used as barrier cover soil at the closure of B3 waste storage facilities. This is because the shear strength of the soil is quite good. The minimum value of the soil permeability coefficient (k) for barrier hoods at the closure of B3 waste storage facilities is 10-7 cm/sec. Many residual soils have a soil permeability coefficient (k) of less than 10-7 cm/sec. Because the dominant compound in coal fly ash is silica, mixing this fly ash with residual soil can reduce the value of the soil permeability coefficient (k) and is also expected to increase the shear strength value of the soil. In this study, residual soil samples were mixed with fly ash at 5%, 10%, 15%, 25% and 35% of the dry weight of the soil. This research aims to determine the effect of adding fly ash on the parameters of dry density, shear strength and soil permeability. The tests carried out were standard proctor testing, direct shear test, and Falling-Head permeability testing. The residual soil used in this research came from Hamlet I, Bintang Meriah Village, Pancur Batu District, Deli Serdang Regency. Based on standard proctor testing, the maximum density (gd max) of original soil is 1,410 gr/cm3. The largest maximum density (gd max) was obtained when adding  15% fly ash, namely 1.471 gr/cm3. In the direct shear test, the original soil cohesion value was 0.024 kg/cm² with an internal shear angle of 37.96º. In the variation of adding 15% fly ash, the cohesion value was 0.131 kg/cm² with an internal friction angle of 53.08º. Based on the Falling-Head permeability test, the original soil permeability coefficient value was 1.98 x 10-6 cm/s. The permeability coefficient value for variations in adding 15% fly ash was obtained at 8.02 x 10-8 cm/s.","PeriodicalId":14205,"journal":{"name":"International Journal of Research in Vocational Studies (IJRVOCAS)","volume":"45 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140477715","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}
