Abstract: The learning tools developed are contextual learning tools on global warming material for class XI SMA, consisting of a Learning Implementation Plan (RPP), Student Worksheets (LKPD), and Learning Outcomes Test. The purpose of this study was to determine the validity of contextual learning tools on global warming material. This type of research is research and development (R&D) with a 4D model. The instruments used were the RPP validation assessment sheet, LKPD, and the Learning Outcomes Test which were used by the validator to assess learning tools. The data analysis in this study used descriptive analysis, by calculating the validity score of each indicator of the learning device. Based on the results of the validity data analysis, the average validity of the RPP at the first and second meeting was 3.12 and 3.15 with the high category (T), the average validity of LKPD 01 and 02 was 3.04 and 3.07. with the high category (T), and the average validity of the Learning Outcomes Test of 3.05 with the high category (T). Thus the contextual learning tools developed are declared valid and suitable for use by senior high school students in class XI on global warming material.Key Words: Device development, Contextual Learning, Global Warming

Abstract

Biosand filter adalah salah satu teknologi yang dapat diterapkan untuk mengolah air limbah domestik skala rumah tangga. Penelitian ini bertujuan untuk menganalisis kombinasi aerasi, biosand filter dan adsobsi dalam menurunkan COD dan fosfat, mengkaji pengaruh debit terhadap penurunan COD dan fosfat.  Reaktor terdiri dari bak aerasi volume 50 L dengan aerator terdifusi dengan tipe TAKARI AT-350, kolom biosand filter dari pipa PVC 8” tinggi 75 cm dengan media pasir halus, pasir kasar dan kerikil, dan kolom adsorpsi dari pipa PVC 6” tinggi 15 cm dengan adsorben karbon aktif granul. Penelitian dilakukan dalam skala laboratorium dengan sistem batch. Variasi yang digunakan adalah debit aliran 0,9 ml/detik dan 3,6 ml/detik. Reaktor beroperasi selama 7 hari, pengambilan sampel dilakukan setiap hari pada inlet dan outlet. Hasil penelitian menunjukkan bahwa semakin kecil debit semakin tinggi penurunan COD dan fosfat. BSF1 debit 0,9 ml/detik dapat menurunkan COD sebesar 92% dan fosfat 88%; BSF2 debit 3,6 ml/detik dapat menurunkan COD sebesar 75% dan fosfat 78%. Kata Kunci : Aerasi, Air Limbah Domestik, Biosand Filter, Karbon Aktif. The biosand filter is a technology that can be applied to treat domestic wastewater on a household scale. This study aims to analyze the combination of aeration, biosand filter, and adsorption in reducing COD and phosphate, examine the effect of discharge on the reduction of COD and phosphate. The reactor consists of an aeration tank with a volume of 50 L with a diffused aerator of the TAKARI AT-350 type, a biosand filter column made of 8” PVC pipe 75 cm high with fine sand, coarse sand and gravel media, and an adsorption column made of 6” PVC pipe 15 cm high, with granular activated carbon adsorben. Research on a laboratory scale with a batch system. Variations used are flow rates of 0.9 ml/second and 3.6 ml/second. The reactor operates for 7 days, sampling is done every day at the inlet and outlet. The results showed that the smaller the discharge, the higher the decrease in COD and phosphate. BSF1 discharge of 0.9 ml/second can reduce COD by 92% and phosphate by 88%; BSF2  of 3.6 ml/second can reduce COD by 75% and phosphate by 78%.  Keywords: Activated Carbon, Aeration, Biosand Filter, Domestic Wastewater.

Abstract

Abstract : This study aims to describe students' conceptual understanding and determine the improvement of students' conceptual understanding by applying a role playing type of cooperative learning model. The type of research used is Quasi Experimental, with a Nonequivalent Control Group Design. The subjects of this study were students of class VII MTs N 1 Padangsidimpuan, which consisted of 60 students and was divided into two classes, namely the experimental class and the control class. The data in this study were in the form of students' concept understanding scores after learning science by applying a role playing type cooperative learning model which was analyzed descriptively. Furthermore, the increase in understanding of the concept was analyzed using the SPSS Version 25 application for inferential analysis. Based on descriptive analysis and inferential analysis of data, it was found that the increase in students' conceptual understanding in the experimental class was in the good category with concept understanding in the good category with a posttest score of 73.05, while the control class was in the sufficient category, which was 58.17. Thus, it can be concluded that the application of the role playing type of cooperative learning model can improve students' conceptual understanding at MTs N 1 Padangsidimpuan.Key words : Learning Model, Role Playing, Concept Understanding

Abstract

This research utilized the Physics At School application to utilize the Learning Cycle 8E model to explain students' conceptual mastery in class X SMA and identify any disparities in conceptual mastery for students in class X SMA. This kind of research uses a quantitative Nonequivalent Post-Test Control Group Design research design and a Quasi-Experimental research method. This research was performed at SMA Negeri 1 Teluk Kuantan using a concept mastery test on the material from Momentum and Impulse. The experimental class, which implements the Learning Cycle 8E model with assistance from the Physics At School program, is one of the two classes used in this research. In contrast, the second class uses conventional learning techniques as a control class. The data used in this research were concept mastery scores obtained from students who had learned physics using the Learning Cycle 8E model with assistance from the Physics At School program. Furthermore, the SPSS version 25 application for inferential analysis was used to examine the improvement in conceptual mastery. Based on a descriptive and inferential examination of the data, it was determined that the experimental class students' level of concept mastery increased by 73.08 points, while the control class was 69.70. In light of this, it can be said that the Learning Cycle 8E model, which is supported by the Physics At School application, has an impact on how well SMA Negeri 1 Teluk Kuantan children understand certain concepts.Key Words: Model Learning cycle 8E, Application Physics at school, Concept Mastery

Abstract

Sweet corn is a horticultural crop that is in great demand by the people of Indonesia. The need for sweet corn continues to increase. Seed varieties with low quality and quality lead to low production yields. Efforts to increase the production of sweet corn include the use of superior varieties. To obtain superior varieties, several lines can be tested by crossing and mutation methods using gamma-ray irradiation. This study aims to obtain the best lines in the MS-UNSIKA variety M7 sweet corn. The research was conducted in November 2022 – February 2023 on land owned by PT. Corteva Agriscience, Ciwaringin Village, Lemahabang District, Karawang Regency. The research method used was an experimental method using a single factor Randomized Block Design (RBD). There were 13 treatments and repeated 3 times so that there were 36 experimental plots consisting of treatments SR1, SR3, SR4, SR5, M6, M8, M9, M10, G11, G12, G13, G14, and G15. If there is a significant effect, further analysis of the DMRT (Duncan Multiple Range Test) is carried out at the 5% level. The results showed that the best average in the treatment of the SR1 strain variety MS-UNSIKA included cob weight with husks 283.00 grams, cob weight without husks 249.50 grams, cob length 20.45 cm, cob diameter 48.00 mm, number of row of 18 seeds, weight of 100 seeds 0.98 gram and yield of 6.80 kg/plot.
