Abstract

Abstract: The biosorption of well water using biosorbent from areca fiber waste of Jambi province has been performed to elevate well water quality. In environmental preservation, this research aimed to reduce a solid waste of areca fiber waste, which has only been burned so far. This activity would increase carbon emissions in the atmosphere. These materials were obtained using carbonizations (300 and 400 oC) and without carbonization. The proper material is used as a biosorbent was 400 oC sized 200 mesh. The material showed several functional groups on the biosorbent surface, such as hydroxyl, amide, amine, and carbonyl. Interestingly, using this material, the water quality can be increased by treatments of odor, color, pH, TDS, TSS, and E. coli under conditions 1.25 g biosorbent, 50 oC, and 150 rpm for 30 minutes. The adsorption results were compared with the value from the standard of Permenkes No.146/Menkes/Per/IX/1990. Based on the explanation, it is resumed that biosorbent derived from areca fiber waste is effective, inexpensive, and easy to operate for increasing well water quality.Abstrak: Adsorpsi air sumur menggunakan biosorbent dari limbah sabut pinang Provinsi Jambi telah dilakukan untuk meningkatkan kualitas air sumur. Pada pelestarian lingkungan, penelitian ini bertujuan untuk mengurangi limbah padat sabut pinang, yang selama ini hanya dibakar. Kegiatan ini akan meningkatkan emisi karbo ke atmosfir. Material-material ini diperoleh menggunakan karbonisasi (300 dan 400 oC) dan tanpa karbonisasi. Material yang tepat digunakan sebagai biosorben adalah 400 oC berukuran 200 mesh. Material ini memperlihatkan beberapa gugus fungsi pada permukaan biosorben, seperti hidroksil, amida, amina, dan karbonil. Menariknya, penggunaan material ini, kualitas air dapat ditingkatkan menggunakan treament aroma, warna, pH, TDS, TSS, dan E.Coli pada kondisi 1,25 gram biosorben, 50 oC, 150 rpm, dan selama 30 menit. Hasil adsorpsi dibandingkan dengan nilai standar Permenkes No.146/Menkes/Per/IX/1996. Berdasarkan penjelasan, hal ini disimpulkan bahwa biosorben dari limbah sabut pinang efektif, dan mudah untuk menggunakan untuk meningkatkan kualitas air sumur.

Abstract

This study is discusses about the implementation model of learning cooperative type make a match on the subjects of Natural Sciences (IPA) Integrated, especially in grade VIIIA students of Baiturrahim Junior High School Jambi City. The purpose of this research is to know the application of cooperative learning model type make a match can help improve students' learning results in Natural Science lessons in grade VIII Baiturrahim Junior High School Jambi City. This research uses Class Action Research which consists of four stages in each cycle namely planning, action, observation and reflection. As for the data on the increase in the percentage of learning completion: before the implementation of learning research by applying the make a match (Pre cycle) model, the number of students who achieved learning completion was the number of 8 students (38.1%). Then after the percentage of learning completed in cycle I learning increased to 15 students (71.4%), cycle II increased to 20 students (95,23%). From these results can be concluded that the application of cooperative models of make a match type can improve students' learning outcomes in human digestive system materials and gastrointestinal tract.

Abstract

The preliminary research was conducted to explore the potency of Areca fiber waste (Areca catechu L) from Tanjung Jabung Timur, Jambi Province as carbon source which would be used as a raw material in biosorben production. Activated carbon production was carried out using physical activation on 400 ͦ C, 300 ͦ C, and without carbonization. The collected activated carbon was sifted using 100 mesh sieve. The biosorbents were characterized by water content, ash content, functional groups, and surface area. Based on the result of this research, it could be concluded that carbonization process can disclose the material pores to increase adsorption. The water content, ash content, and surface area of 300 ͦ C sample were 2 %; 45,72 %, and 25,77 m2g-1, respectively.The functional group on the surface of biosorbent would be interacted with adsorbat in adsorption process.

Abstract

The purpose of this study is to investigate whether or not teaching biology to students at SMAN 2 Merangin using the Predict Observe Explain learning model has an effect on the cognitive learning outcomes of students. This study employs a One-Group Preetest-Posttest Design with a quantitative pre-experimental methodology. Total sampling was used, which means that all students in class X IPA 1 which amounted to 22 people were included in the research sample. Learning outcomes were assessed with a 30-question multiple-choice test used as the research instrument. Students' cognitive learning outcomes were calculated by means of a pre-test score of 77.87, a mean post-test score of 81.96, and a significance value of 0.000) <0.05 using a t-test. If the Effect Size is considered to be 0.00 or 50%, then the results show that H_a is accepted and H_o is rejected. That is, the Predict Observe Explain Learning Model has an effect on the cognitive domain of biology learning outcomes for class X IPA 1 SMAN 2 Merangin

Abstract

One way to evaluate general biology practicum is to know the students' perceptions of general biology practicum. This study aims to determine student perceptions of general biology practicum, general biology practicum planning, facilities and infrastructure of general biology practicum, and also to determine the perceptions of students towards the implementation of general biology practicum majoring in biology IAIN Kerinci. This research belongs to the category of qualitative research. To get the data the researcher used the study (1) Observation, observed the general Biology practicum, (2) Interview, semester 1 student lecturer and department head, (3) Documents, data about vision and mission department, and general Biology practicum guide. The results obtained based on the results of data analysis and discussion can be concluded (1) Perception of the General Biology practicum planning Department of Biology Tadris IAIN Kerinci is quite good. (2) Perception of the first semester biology student of IAIN Kerinci regarding the facilities and infrastructure of general biology practicum namely practicum guide is still incomplete and inadequate. (3) The first semester biology student IAIN Kerinci's perceptions regarding the implementation of general boiology practicum, firstly in each practicum the teaching assistant is still not right to use the strategy properly. Second, the media displayed is good, and also for the practicum schedule it has been said on schedule.
