Abstract

The Purpose of this study aims to determine differences in learning outcomes using media comics through cooperative learning model type TAI and cooperative type STAD on the material of Chemical Bonds and knowing the differences in interest in learning with models TAI type cooperative learning on Bond material Chemistry. The population in this study were all students of class X IPA in SMA Private Harapan Medan, which consists of three classes. The sample used in this study; two classes were taken using the purposive sampling technique. The instrument with 20 questions that are valid and reliable. Learning outcomes data in te Normality tes with a value of sig.0,06 and 0,00 (0,05) means that the learning outcomes data are normally distributed. Test the homogeneity of the result data learning 0,603 0,05, it can be concluded that the variance of learning outcomes data on Experiments 1 and 2 are homogeneous. Hypothesis testing was carried out with Two Sample, the learning outcomes (2-tailed) 0,080(0,05) and student interest (2-tailed) 0,65(0,05) so that Ha is accepted and HO is rejected, it can be concluded that there is Differences in student learning outcomes between those who are taught using the model TAI and STAD cooperative learning with what is taught by comics media at the subjects of the Chemical Association and there are differences in student learning interests between students those who are taught use the TAI cooperative learning model and STAD with what comic media teaches on the subject of the Chemical Association. By therefore the TAI and STAD type cooperative learning models with comic media on chemically bonded material are suitable for use.Keywords : Cooperative Learning Model Type Team Assisted Individualization ( TAI) and Students Teams Achievement Division (STAD), Media comics, learning outcomes, interest in learning, chemical bonds

Abstract

Adsorbent is an adsorption that is used to absorb various pollutants. Adsorbents can be used from natural materials. Natural ingredients that can be used are oil palm empty bunches. Oil palm empty bunches are a carbon-rich material that is getting new research interest in adsorption because of its abundance and properties. Oil palm empty bunches contain carbon, nitrogen, hydrogen, oxygen, sulfur, lignin, hemicellulose, and cellulose. Oil palm empty bunches are used as adsorbent for water saturation.

Abstract

Problem Based Learning (PBL) learning model is a set of learning activitiesthat emphasize the process of solving problems faced scientifically. The use ofvideo media can help students' learning process and will have a big impact onthe learning outcomes of thermochemical material because almost everyone,from children to the elderly, now has a smartphone. In addition to learningvideos, powerpoint is one of the learning media that can help students who havelearning difficulties. The purpose of this study was to determine whether thethermochemistry learning outcomes taught using PBL-based learning videoswere higher than the thermochemistry learning outcomes taught using PBLbased PPT. This study involved the experimental class I and the experimentalclass II. From the results of the study, the average pre-test for the experimentalclass I was 41,95 and the experimental class II was 41.44. After being treatedwith learning in both experimental classes, post-test was then recommended todetermine learning outcomes, the post-test average of experimental class I was83.14 and experimental class II was 78.44. The results showed that theexperimental class I which was taught by learning video media and the PBLmodel was higher than the learning outcomes of the experimental class II whichwas taught by the powerpoint media and the PBL model. It can be concludedthat the use of instructional video media, learning outcomes are higher than theuse of powerpoint media.

Abstract

This study aims to the learning outcomes learning activities and a significant correlation beetweenlearning outcomes and student activities thar were taught with the TTW mode assisted and NHT on chemical of basic laws and chemical calculations matter at SMA Negeri 2 Tanjung Morawa. From the result of data analysis obtained for learning outcomes students who are taught with TTW model (83,67) are higher than NHT (66,21). So hypothesis testing is carried out using one sample t test at a significant level of 5 % showing that in learning outcomes tcount > ttable ttabel (8,63 > 1,67). Whereas learning activities that were taught in TTW model (82,76) are higher than the learning activities NHT (61,53). For hypothesis testing showing than in learning activities tcount > ttable (8,39 > 1,67). So there is significant correlation between learning outcomes and student activities taught with TTW model. The results of correlation the two variables are included in the high category.

Abstract

Kegiatan PKM dilatarbelakangi oleh usaha ternak kambing yang mengalami kekurangan pakan hijauan dan kesulitan peternak untuk meningkatkan produksinya. Hal ini berdampak pada produksi dan reproduksi ternak kambing yang rendah. Sementara itu, perkebunan Amal Tani menghasilkan limbah berupa pelepah daun kelapa sawit. Limbah ini cukup berlimpah sepanjang tahun dan belum dimanfaatkan secara optimal. Potensi ini dapat digunakan untuk mengembangkan pakan komplit dengan memanfaatkan pelepah sebagai sumber serat sehingga dapat menjadi pakan alternatif pengganti pakan hijauan. Metode pelaksanaan PKM ini adalah menjalin kerjasama Tim Pelaksana dan LPM UNIMED, penyuluhan dan pelatihan kepada kelompok mitra. Dalam kegiatan ini Tim pelaksana telah mensosialisasikan tentang program Pengabdian, tujuan kegiatan, target dan luaran yang akan dicapai, dan untuk meningkatkan pengetahuan masyarakat mitra telah dijelaskan tentang pemanfaatan limbah pelepah sawit menjadi pakan ternak kambing/sapi. Melalui teknologi pakan ternak silase dari limbah pelepah daun kelapa sawit di Desa Perkebunan Amal Tani diharapkan masyarakat tidak lagi tergantung pada pakan hijauan alami dalam pemenuhan konsumsi pakan ternak.

Abstract

Education in Indonesia since middle-March 2020 has undergone significant changes. Online learning to answer questions is a solution to the virus problem that has spread to cut cases of the Covid-19 virus using online media. Edmodo is a learning application that the application can use in bold type learning, including atomic structure material. This study analyzes the Edmodo-based understanding used for learning media on atomic structure material and how students respond to the Edmodo application in chemistry learning, especially atomic structure material. The research method used is descriptive qualitative. The results showed that the effectiveness of learning was 69%, application sustainability during the pandemic was 76%, ease of access was 97%, ease of communication was 61%, the clear assessment was 84%, and understanding of the material Edmodo was 59%. Implementing chemistry learning consists of (1) choosing Edmodo as a bold learning medium in chemistry learning based on analyzing student needs with reasoning and mastery of applications; (2) planning the application as a student learning medium as described in the Semester Learning Plan; (3) implementation in Edmodo-based online learning is carried out well and smoothly based on semester learning plan; and (4) edmodo as an application can help carry out chemistry learning in atomic structure subjects to measure student learning outcomes. So it can be concluded that Edmodo is a practical application to use during the Pandemic of Covid-19. Keywords: Covid-19 virus, edmodo, implementation of edmodo, online learning

Abstract

Biosorbent derived from agricultural waste as one of the widely used adsorbents has many applications in the environment to remove pollutants, one of which is heavy metal copper (Cu). In this paper, natural sources of agricultural waste materials have been reviewed and have potential as biosorbents for the absorption of heavy metal copper (Cu). The characteristics of the biosorbent that can be used for the absorption of heavy metal copper (Cu) depend on the surface area and pore structure made by the modified method. The biosorbent modification method depends on the precursor and the expected biosorbent characteristics. Natural biosorbents can be converted into modified biosorbents by chemical, physical, or physico-chemical modifications. Therefore, this paper aims to provide information about the absorption of adsorbents from agricultural wastes that have been reported for the absorption of heavy metal copper (Cu) in wastewater
