Abstract

This study aims to determine the effect of generative learning model on theability of student analysis on matter of human nervous system at XI IPA class at Musi Rawas. This research uses quasi experiment method of non-equivalent control groupdesign. The research population is the students of XI IPA class with sampling technique using non probability of purposive sampling. Based on the analysis result, it shows that the mastery in the experimental class is 67,7% higher than the control class that is 55,3%. The improvement of analytical ability can be seen from the value of N-gain with the experimental class has a value of N-gain of 0,53 and the control class is 0,19 with low category. The results of hypothesis testing using t-test obtained by value tarithmetic =3,969 and ttable =1,670 confidence level of 95%, ( = 0,05). The data shows that t arithmetic >t table , then H0 is rejected and Ha is accepted. Therefore, it can be concluded that the generative learning model has an effect on the students' analysis ability at XI IPA class.Keywords: analytical skills, nervous system,generative learning

Abstract

Problem based learning model is a learning that is done by confronting students on real problems in everyday life so that students can develop their own knowledge in solving problems and seeking various solutions, which encourages students to think creatively. This study aims to determine the implementation of learning by using problem-based model to determine the effect of model problem based learning on students' creative thinking ability on cell material in the classroom. The design of this research is using Pretest-Posttest Only Control Design design with Quasi-Experimental design method. The sample of the study is 84 students. Based on the results of the analysis, students' creative thinking ability shows that the implementation of learning by using problem-based learning model is better than the control class. The result of this research can be concluded that the problem based learning model influences the students' creative thinking ability. For students, in following the learning with Problem Based Learning model is expected to improve students' creative thinking ability by directly involved in learning in the classroom. For teachers, it is expected to use Problem Based Learning model in learning activities in order to create an active and creative learning process. For schools, it is expected to provide advice and motivate teachers to use appropriate and varied learning models in the learning process. For further research, it is expected to use Problem Based Learning model in other materials, and also can use other learning model. Keywords : cell, creative thinking, learning, PBL

Abstract

Pineapple (Ananas comosus (L.) Merr. 'Prabumulih') is a tropical fruit that is very popular for its unique aroma and sweet taste. It is also commonly believed that this fruit has potential applications in traditional medicine. However, the peel is not fully harnessed, despite its rich and intricate composition. This study presented findings regarding the endophytic fungi discovered within the peel of A comosus (L.) Merr. 'Prabumulih' and their performance as antioxidants. The endophytic fungal species were identified based on their morphological characteristics. The antioxidant assessment was carried out using the DPPH method. According to the findings of morphological identification, Trichoderma harzianum, an endophytic fungus, was found to exhibit the highest potential as an antioxidant source. Antioxidant activity showed a very strong category (IC50 = 18.74 µg/mL). Through the isolation of its pure constituents and subsequent in vivo testing, there is the potential for this extract from the endophytic fungus to evolve into an innovative source of antioxidants.

Abstract

Searching for medicinal raw materials derived from the isolation of secondary metabolite compounds is still being carried out to cure a range of illnesses, including infections and degenerative diseases caused by bacteria and free radicals. This research used endophytic fungi extract from the twig of Syzygium malaccense. The diffusion method was used for antibacterial activity and 2,2-diphenyl-1-picrylhydrazyl (DPPH) was used for antioxidant activity. Chemical compound was identified by using NMR spectroscopic method. This research found 5 isolate of endophytic fungi from twig of S. malaccense (YR1 – YR5). Strong antibacterial and antioxidant activity were showed by YR5. Based on molecular identification, YR5 was Fusarium verticillioides. Pure compound prodeced by endophytic fungi F. verticilloides was naphthalene (3-methoxy-7 methylnaphthalene-1,6-diol). This finding can be used as a basis for drug development.

Abstract

Air bersih memiliki indikator secara fisik, kimia dan mikrobiologi. Penelitian ini menggunakan indikator air fisik dan mikrobiologi yang menggunakan parameter bakteri Coliform, seperti keberadaan E.coli per ml air sampel. Pemeriksaan air dilakukan setelah menyaring air dengan menggunakan prinsip teknik Gravity Fed Filtering System dan penambahan arang aktif batok kelapa untuk mendapatkan air bersih. Pemberian Arang aktif menggunakan 4 perlakuan dalam penyaringan yaitu penambahan arang aktif sebanyak 50 g, 100 g, 250 g dan 500 g. Hasil penelitian menunjukkan bahwa pada takaran 50 g arang aktif dengan komposisi 2 kg pasir dan 2 kg kerikil dan pemakaian spons dapat menyaring air sungai dan sumur dengan karakteristik fisika nya yaitu airnya jernih, tidak berwarna dan tidak berbau. Sedangkan pemeriksaan secara kimianya yaitu memiliki nilai pH 7,33–7,46 yang menunjukkan bahwa pH air memenuhi standar air bersih. Kemudian hasil penyaringan akan dilanjutkan dalam pemeriksaan mikrobiologi. Setelah dilakukan pemeriksaan mikrobiologis, diketahui bahwa air sampel hasil saringan pada takaran arang aktif 50 g dengan menggunakan media LB dan BGLG tidak mengandung bakteri E. coli dan Coliform. Air hasil penyaringan dengan arang aktif pada takaran 50 g diasumsikan dapat digunakan untuk keperluan sehari-hari.

Abstract

Clean water is a basic need for society. However, the problem of clean water sources still occurs in the Ogan Komering Ilir (OKI) area of South Sumatra Province. The condition of the water being brownish and oily is an unresolved problem. One source that has the potential to disrupt water quality is the presence of factories around rivers. This community service activity aims to identify water quality and provide training to the community regarding river water management strategies and drilled wells as the primary water source for obtaining clean water, as well as increasing understanding and knowledge about clean water management with the Gravity-fed Filter Technique. The method of activities related to clean water quality is carried out in four stages, namely: 1) Location survey (cross-sectional), 2) Water sampling and laboratory analysis, 3) Education on water quality standards, and 4) Training on Gravity-fed Filter Techniques. The laboratory analysis showed that the water samples smelled fishy and were brownish and oily. In addition, the results of microbiological tests on water samples contained Coliform bacteria (sanitation indicator bacteria), which were outside the provisions of Minister of Health Decree No. 907/MENKES/SK/VII/2002 concerning clean water quality requirements. Through training activities using the Gravity-fed Filter technique, the pH and bacteria contained in the water can be reduced. Clean water management strategies using the Gravity-fed Filter technique can be used as a solution to improve clean water quality. Every society can apply the Gravity-fed Filter technique. Through this activity, society has managed water sources into clean water for daily needs.

Abstract

Metacognitive skills help students think, manage their knowledge, analyze and solve problems, understand their learning methods and strategies, and think critically. Guided inquiry learning trains students to think critically, analyze, evaluate, and build information based on their acquired knowledge. This study aims to investigate students' metacognitive skills through guided inquiry learning on the material of Plant Structure and Function. The type of research used is Pre-Experiment with One-Group Pretest-posttest design. The sampling technique used saturated samples with a sample size of 19 students. The research instruments used were pretest and posttest questions on metacognitive skills with planning, monitoring, and evaluation indicators. Data analysis used the Wilcoxon non-parametric test. The results of the increase in cognitive skills in the pretest and posttest were indicated by the N-gain value of 0.59 with the Medium category. The results of the data analysis obtained the Asymp value, sig < 0.5, which is 0.00, which means that HI is accepted. This shows that learning using guided inquiry can affect students' metacognitive skills.
