Abstract

This study aimed to determine student learning outcomes using the Synectic learning model and learning outcomes using conventional learning models at YAPIM Taruna Dolok Masihul Private High School. The population was all students of class XII SMA which consisted of 2 classes. Samples were taken randomly from 2 classes consisting of the experimental class and the control class. The data observed were chemistry students' learning outcomes, which were collected through a multiple choice test of 20 questions consisting of 5 answer options, which had been tested for validity, reliability, difficulty level and test differentiation. The data obtained were analyzed using the T test, which previously tested the normality and homogeneity of the data. The learning outcomes of the experimental class mean pre-test (27.81 ± 7.21) and post-test mean (76.88 ± 5.70) with an increase in learning outcomes Gain by 68%, while the learning outcomes of the control class average pre-test (22.03 ± 6.70) and the average post-test (70.47 ± 6.00) with an increase in learning outcomes gain by 62%. Hypothesis testing is carried out at the significance level ? = 0.05 using one-sided t-test, namely the right side where tcount> ttable (3.05> 1.667139), which means that Ho is rejected and Ha is accepted. By looking at the results of these studies it can be concluded that the chemistry learning outcomes of students who were treated through the application of the Synectic learning model are higher than using conventional teaching.

Abstract

The need for clean water in each area is very urgent, especially in rural areas that lack springs. Discussions are being carried out regarding drinking water needs in Morela village community housing, calculating the capacity requirements for drinking water volume in Morela Village housing and drawing of the existing clean water distribution system installation network. in Morela Village. The study used a quantitative analysis approach to processing primary data obtained from field data samples through the survey to be analyzed. The projection of drinking water until 2027 is 12.449 liters / second, while the availability of water sourced from rivers is based on a discharge analysis of 10.825 liters / second. The process of connecting the flow of clean water from the river to the Morela Village housing, through brouncaptering using the GPS Medium A pipe. 150 mm, 100 mm and 75 mm, water is flowed to a distribution reservoir measuring 6.30m x 8.10m x 2m and from the reservoir the water is flowed through a diameter pipe. 150 mm, 100 mm and 75 mm and flowed directly to the main pipe dia. 50 mm to the housing.

Abstract

Red betel leaf is a plant that is often used by people as medicine and used as an ornamental plant because of its unique shape. Red betel leaves contain the main essential oil consisting of phenols and their derivatives so that they have potency as an antiseptic and antifungal agent. This study aims to determine the effectiveness of the crude fraction of flavonoid compounds from red betel leaf against Salmonella typhi bacteria and the compound content of the most active fraction. The M1, M2, and M4 fractions contain flavonoid compounds and have the ability to be antibacterial with the best potential fraction is in the M1 fraction with an inhibition zone of 4.83 mm.

Abstract

Regression analysis method is one of the statistical methods used to describe the relationship between two or more variables, so that a variable can be predicted from another variable. In regression analysis there are two types of approaches, namely parametric and nonparametric approaches. Estimates used to estimate the parameters in the regression analysis using the OLS method. This method is based on the mean distribution, so it is not appropriate to analyze a number of data that are not symmetrical or contain outliers. Therefore, a quantile regression method and kernel smoothing were developed that were not affected by data containing outliers and could also be used as an alternative to solving fluctuating data problems. This study uses quantile regression with kernel smoothing in the case of factors affecting malaria in Indonesia. The results show that the main factors causing the spread of malaria in Indonesia are access to proper sanitation, household factors that behave in a clean and healthy life, and the number of puskesmas and the percentage of medical personnel.

Abstract

Ebony is a luxury wood that grows endemic to Pulau Buru Maluku with the name Ebony Maluku while the other local name is the wood of Belo Hitam (Diospyros sp).  Eboni is one type of wood that is very much liked by the community and the existence of quite a lot on the island of Buru, but the information about its basic nature is not well known by the local community. The study aims to determine the influence of the wood vertical position (base, middle, and end) and anistropic (radial tangential) areas of the wood physics properties of ebony. The results showed that the moisture content of three parts varies from the base of the stem to the end, while the highest wood density in the trunk is the base, then, the end, and the low at the center. The timber depreciation on three anistropic surfaces indicates the largest depreciation in the tangential field compared to radial

Abstract

This research is more focused on analyzing the projected population growth and the need for Clean Water for the next 10 (ten) years so that it can be systematically planned for the design of the Water and Clean Water infrastructure needs. In order to meet the projected population growth and the need for clean water, it must be known how the population is in accordance with the supply of clean water needed by the people of Lilialy Subdistrict. which will come. The location of this research is in Lilialy Subdistrict and is limited to the population projection whether it is in accordance with the provision of clean water needs needed by the community and to assess and plan for the needs of clean water for the next 10 years. Projection of Clean Water Needs both SPAM and Graphitation System is calculated based on domestic needs and the loss of water is there because Drinking Water and SPAM needs are influenced by population growth in Lilialy District in 2016 domestic and SPAM drinking water needs are 3.11 liters / sec and at in 2024 the need for domestic drinking water is 3.49 liters / second.

Abstract

In Indonesia, one of the companies that produces and supplies fuel is PT Pertamina (Persero). Pertamina continues to develop new service standards to ensure consumers get the best service. SPBU (Public Fuel Filling Station) is a private party working together as a means to distribute products produced by Pertamina. This study aims to determine the effect of service quality on customer satisfaction at local gas stations and to determine the most dominant factor influencing customer satisfaction at local gas stations, using 68 respondents of this study using linear regression methods and t test. Linear regression with equation Y = 3.263 + 0.192X. Based on the results of calculations from the statistical t test between service quality variables on customer satisfaction, obtained t value of 1.787 and t table value of 2.00 This means t arithmetic <t table (1,787 <2.00), meaning that there is no influence on service quality to customer satisfaction, which means that Ho is accepted and Ha is rejected. so, in this case it can be concluded that there is an influence of service quality on customer satisfaction with a significance value of 0.078> 0.05, then Ho is accepted and Ha is rejected, it means there is no influence of Variable X (quality of service) on customer satisfaction (variable Y) so, in this case it can be concluded that there is no significant effect of service quality on consumer satisfaction at the Lala gas station.

Abstract

Learning in the new normal era during the co-19 pandemic will certainly be different from previous learning. Long before covid-19 learning was free to learn individually or in groups, but in this new normal era learning only focused on individuals without group assignments. So from that the purpose of this study is to find out how much the level of effectiveness of learning on student learning outcomes with high interpretation expectations. The method used in this study is a quantitative approach where data is obtained by statistical tests which are assisted with the application of SPSS for windows. The data is accumulated and analyzed by regression analysis so that after a statistical calculation is obtained a value of 73,2% in which a value of that size can be interpreted quite well or it can be said that learning is quite effective in the new normal era.
