Abstract

Palm shells are one of the wastes produced from the processing of crude palm oil in addition to empty fruit bunches and coir which account for 60% of oil production. Palm oil shell waste is widely used as active charcoal in the oil, rubber, sugar, and pharmaceutical industries. The potential of palm oil shell waste in Indonesia is very large considering the area of oil palm plantations which continues to increase every year. This study aims to determine the percentage of the addition of palm oil shell waste in the manufacture of paving blocks that provide optimum compressive strength and water absorption values from several variations of the addition of palm oil shell waste that replaces some of the fine aggregates. The study was carried out experimentally in a laboratory using a boxed specimen with a length of 20 cm, a width of 10 cm, a height of 6 cm by 40 pieces. The mixture uses a ratio of 1 cement and 5 sand with fas 0.3. Treatment of test specimens by immersion in water for further testing of compressive strength and absorption at the age of 28 days. Based on testing of the compressive strength of paving blocks with a percentage of 0%, 5%, 10%, 15% are respectively 8.08 MPa, 7.18 MPa, 6.46 MPa, 5.94 MPa. The value of paving block water absorption with a percentage of 0%, 5%, 10%, 15% are respectively 9.88%, 10.25%, 12.27%, 12.44%.

Abstract

During Entering the 21st century, the globalization is more intensive than previous era for competition in the job market since confidently observed nowadays. In similar side, it is unpredictable and fluctuated following by market demand and market trend. Innovation and creativity are very necessary as the example of this phenomenon in development of science and technology. Some of them can be directly observed such as newest brand of domestic products, innovative services, communication modes, attitudes in communication, the delivery services, and so on. Therefore, the role of Vocational School is being crucial to give the output with standard qualification of alumnus who have experienced on job training in real industrial workplaces. Industrial Job Practices are part of the Dual System Education (PSG) as a joint program between Vocational High Schools and the Business World/Industrial World (DU/DI). The existence of industrial practice, will provide insight and knowledge to students about the real job markets. In addition, by the existence of Industrial Job Practices, students can apply the theories that have been obtained in formal class beforehand to shape their basic and intermediate industrial skills. Based on this background, this study aims to investigate and find out t how Industrial Job Practices might influence the student readiness in entering the real job field and job market by students in Class XII of Building construction engineering competency program in SMK Negeri 1 Palangka Raya at academic year 2018/2019. This research adopts the quantitative-descriptive study where is conducted at SMK N 1 Palangka Raya From 17 May 2019 to 11 June 2019. It is about 69 students of class XII Building Construction Engineering Field Program which is consisting ofrespectively 20 students majoring in Brick and Concrete Construction Engineering, 17 students majoring in Wood Construction Engineering, 32 students majoring in Civil Drawing Engineering. The technique of collecting data implements a closed questionnaire method (questionnaire) while the instrument validity test was carried out in class XII construction engineering competency Program at SMK Negeri 1 Palangka Raya using construct validity. The results of the instrument validity test produces 40 as the valid statement items and 0 being invalid statement which is counted to 40 instruments. In this research, the reliability testing applies Cronbach alpha formula that is followed by the descriptive data analysis technique. The research results showed that there is about 79.87% effecting the readiness of students entering the job field in the Department of Brick and Concrete Construction Engineering as the high category. Nonetheless, it is around 78.38% and 78.85% respectively for students of Wood Construction Engineering program positioning the high category as well.

Abstract

This study is descriptive research with a quantitative approach, the research subjects as many as 131 students from 7 different skill program classes in class XII SMK N 1 Palangka Raya. The questionnaire uses a likert scale and is created in the form of a Google form, then distributed online to students. After that, the data is analyzed using the achievement degree formula (DP) and multiple linear regression analysis. The results showed that the average percentage of interest of students of SMK N 1 Palangka Raya towards the selection of Program Building Engineering Education Study of Palangka Raya University amounted to 72.67% and belonged to the category of quite in demand. While the factors that affect the interest of students of SMK N 1 Palangka Raya continue their studies in the Building Engineering Education Study Program of The University of Palangka Raya, namely self-motivation factors, opportunity factors, social environmental factors and institutional factors are simultaneously indicated with a significance value of less than 0.05 and Fcalculated greater than Ftable (41,898 > 2.44). The most partially significant factor is the institutional factor with tcalculated value greater than the ttable value (7.605 > 1.97897). This research can be developed again, considering that only 55.7% of the free variables discussed in this study are able to explain bound variables,in addition this study can be used as an evaluation material on improving the promotion of PTB UPR Study Program
