Abstract

This research was conducted in July-August 2019 in the northern part of the Poncan Gadang Island Sibolga, North Sumatra Province. This study discusses the distribution and distribution patterns of molluscs (gastropods and bivalves) which contain species, density, and species discussed in the northern part of Poncan Gadang Island, North Sumatra Province. The method used is a survey method, where the research location is divided into 5 observation stations and each station consists of 1 transect and each transect consists of 4 maps. The results showed that the type of gastropods found in the study site consisted of 11 species belonging to 6 families. Gastropod species that are commonly found are Littorina littorea. While the type of bivalves that were found at the study site consisted of 9 species belonging to 6 families, and the bivalves species that were found were Anadara granosa. Highest density at station III in the river mouth. Various index (H ') of gastropods and bivalves in all research stations are included in the medium category. Distribution Patterns both gastropods and bivalves are distributed in groups. The index value of approved gastropod and bivalve types (Ss) can be requested types which are found to be quite the same. The substrate at the study site was approved by the sand substrate. The density of both gastropods and bivalves were not significantly different between stations.

Abstract

Oil palm trunk is one of the biomass that has not been utilized and becomes waste in the former oil palm replanting location. The application of palm oil processing technology for furniture raw materials can provide solutions to target audiences to be utilized and developed in the future. The aim of the community service activity is to assist the processing of oil palm stems for the production of furniture that has distinctive features and high selling value. The method of implementing the activity is theoretical assistance and direct practice to target audiences regarding palm oil processing technology for decorative furniture products. Achievement measurement tools consist of theoretical understanding and application suitability in the field. The results of these activities can be implemented by various prototypes of furniture products. The partner's knowledge of the wood processing business makes the transfer of science and technology for the use of oil palm trunks easier to implement. Socio-economically for the local community is very beneficial because it can change the perception of the existence of palm oil stems which have been considered as waste into a potential that can be utilized for an economically valuable product.

Abstract

The main objective of the research is to establish a sustainable Siak River pollution management strategy, in an effort to accelerate (quick win) the strategic policy of Siak River pollution management which is one of the National Strategic category rivers located in the Sumatra Region based on Presidential Decree No. 12 of 2012 concerning the Determination of the River Basin, because the Siak River has a very large function and role in regional and economic development both locally, regionally and nationally. The approach method used is Multi Criteria Decision Making (MCDM) with the selected method of Analytical Hierarchy Process (AHP). The primary data is in the form of questionnaire data with the aim of being assessed by experts (expert judgment) who are considered competent in assessing the processing of Siak River pollution. Seven respondents identified who have the potential and are representative to contribute to obtaining expert judgment recommendations consist of Universities represented by the University of Riau (UR), the Riau Province Environmental Agency (BLH), the Sumatran Ecoregion Development Control Center, Non-Governmental Organizations (NGO) Jikalahari, Center for Watershed Management (BPDAS) Indragiri Rokan. Regional Research and Development Agency for Riau Province and the River Basin Center (BWS) III Sumatra.            The main results of the study stated that the Siak River water pollution control strategy using the AHP approach sequentially was to rearrange the spatial function, determine the pollution load capacity (DTBP), coordination of stakeholder synergies, program socialization and counseling, supervision and monitoring, law enforcement and development. Wastewater Treatment Plant (WTP).

Abstract

The use of learning media is considered very appropriate and effective to be applied to early childhood. One of the learning media that can help children get to know geometric shapes is geo lane media. This study aims to determine the influence of geo lane media on the ability to recognize geometric shapes of children aged 4-5 years at Taqwa Al Hidayah Danto Kindergarten. The type of research used is experimental quantitative research with the research design One Group Pretest-Posttest Design with a total sample of 15 children. The data collection technique used in this study was to use an observation sheet to recognize geometric shapes. The data analysis technique uses a t-test using the SPSS ver 23 program. The results showed that there were differences in the ability to recognize geometric shapes before and after using geo lane media. Judging from the average number before using geo lane media is an average of 44% and the average value afterwards is 98%. Based on the t-test using the Paired Sample Test, the results of the calculated t test = 11,525 with Sig = 0.000 were obtained. Since the value of Sig < 0.05, means significant. It can be concluded that sig (2-tiled) 0.000 < 0.05. This means that there is a significant influence of geo lane media on the ability to recognize geometric shapes of children aged 4-5 years between before and after using geo lane media.

Abstract

Geometry ability is an ability that needs to be learned from an early age. Mini cinema games can be one of the simple games designed to help children aged 4-5 years recognize geometric shapes. This study aimed to determine the influence of mini cinema media on the ability to recognize geometric shapes in TK Aisyiyah 2, Mandau Duri District. The research used was experiment conducted with a one group pretest-posttest research design, namely experimental research conducted in one group. The data analysis technique was paired samples t-test using the Statistical Program for Social Science software (SPSS version 25). The results of this study indicated that there is a very significant effect of using mini cinema media on the ability to recognize geometric shapes before and after carrying out the experiment by giving treatment in the form of mini cinema media in children aged 4-5 years at Aisyiyah 2 Kindergarten, Mandau Duri District. The effect is equal to 71.42%, and based on the Normalized Gain assessment criteria, it is in the medium category.
