Abstract

Kemandirian belajar siswa yang kurang dapat menyebabkan hasil belajar kognitif yang diperoleh juga kurang optimal. Hal ini dapat terjadi karena model pembelajaran yang digunakan di sekolah masih berupa model pembelajaran langsung (direct learning). Penelitian bertujuan untuk mengetahui pengaruh implementasi model pembelajaran flipped classroom terhadap kemandirian dan hasil belajar kognitif siswa. Desain penelitian eksperimen semu dengan rancangan non-equivalent pre-test post-test control group design. Teknik pengambilan sampel dengan purposive sampling dan dilakukan uji prasyarat dengan uji normalitas dan homogenitas. Sampel penelitian adalah kelas X MIPA 2 dan X MIPA 4 dengan jumlah masing-masing siswa adalah 36 siswa. Teknik pengumpulan data menggunakan angket, tes hasil belajar, dan observasi keterlaksanaan model pembelajaran. Teknik analisis data dengan uji normalitas, homogenitas, dan pengujian hipotesis dengan uji ancova. Hasil penelitian diperoleh model pembelajaran flipped classroom berpengaruh signifikan terhadap kemandirian dan hasil belajar kognitif siswa

Abstract

This study aims to determine the pH variation of the growth of Bacillus cereus strain IMB-11 in degrading diesel fuel. The research was conducted in the Laboratory of PMIPA, FKIP, Universitas Riau while total petroleum hydrocarbon (TPH) was measured in the solid residue in the Laboratory of the Faculty of Civil and Environmental Engineering, ITB. This research was conducted in November 2019 – March 2020. The study was designed in a completely randomized design with 3 treatments and 3 replication groups. The media used are SMSS media with the addition of pH 6.5; pH 7.0; and pH 7.5, which was added with diesel fuel as much as 5% and bacterial isolates of Bacillus cereus strain IMB-11. The test parameter was the optical density (OD) of bacterial growth of Bacillus cereus Strain IMB-11 which was monitored using a spectrophotometer for 6 days and the measurement on the level of degradation or TPH diesel fuel using the Gravimetric method. Based on the research, the moderate pH of 7.0 was the best condition for strain growth with an OD of 5.8 with 26.95% of degradation rate of diesel fuel in vitro.

Abstract

Oyster mushroom (Pleoratus ostreatus) is one of the mushroom species cultivated by residents of Pasar VI Kualanamu Village, Beringin District, Deli Serdang Regency, North Sumatra Province. Residents gain knowledge of oyster mushroom cultivation through the training provided. Therefore, researchers are interested in conducting research in Pasar VI Kualanamu Village. The purpose of this study is to determine the biotic and abiotic components that can affect the growth of oyster mushrooms and what efforts need to be made so that they can cultivate oyster mushrooms and increase their production. The research carried out is a type of field research that is descriptive qualitative, namely research that describes existing phenomena by finding patterns of interactive relationships, discovering new theories, describing complex realities and gaining understanding of meaning. In this study, the researcher was involved as a participant observer to further explore the research process carried out. From the results of the study it can be concluded that the biotic and abiotic components that can affect the growth of oyster mushrooms (Pleurotus ostreatus) are kumbung building materials (mushroom houses), pests in kumbung (mushroom houses), sunlight, water, sterilization of materials (wood powder & bran), soil temperature and humidity, planting and harvesting media

Abstract

Chili pepper (Capsicum frustescens) is herbaceous plant from the family Solanaceae which is massively cultivated in Indonesia. It also can be used as raw material for food product and pharmacy industries. Organic fertilizer usage has been both a solution to increase productivity and a replacement to chemical fertilizer usage. The aim of this study is to examine the effect of compost tea organic fertilizer and JADAM Microorganism Solution (JMS) on the growth of chili pepper in PT. Cinquer Agro Nusantara, Bangka Belitung. This research used a completely randomized design with 15 unit treatments which were divided into control group, compost tea group, and JMS group. The result showed that the plant group with JMS performed the highest height expansion, increasing the number of leaves significantly compared to control and compost tea group. This study concludes that application of compost tea and JADAM Microorganism Solution (JMS) as organic fertilizer on C. frustescens can increase the plant’s growth.Keywords : chili pepper, compost tea, JADAM microorganism solution

Abstract

Powdery mildew is one of melon disease caused by ascomycetes fungus from genus Sphaerotheca and Erysiphe. Breeding is considered to be the best approach to control Powdery mildew infection especially in melon. MG3 is a melon cultivar derived from ‘MG1’ x ‘Ladika’ and its estimate carry out resistant gene to Powdery mildew infection inherited from MG1. This research is to find out percentage and phenotype characters of Powdery mildew infection in MG3 compared to four commercial melons (Action 434, Glamour, MAI and ladika) that are popular in the market. Five melons are planted in greenhouse B of KP4 UGM. After five weeks, the plants where inoculated with Powdery mildew KP4 UGM in leaves. Scoring in three days after inoculation and the percentage of infections measured every 3 days for eight times using grid line 21 cm x 21 cm with small cubics 1,5 cm x 1,5 cm. The analysis of infections level in leaves, plant and population was done using Fukino protocol. The results show that cultivar MG3 tolerant and stable to Powdery mildew infection compare to cultivar Action 434, MAI and ladika in leaves, plant and population level. The infection of Powdery mildew caused damage to the leaves tissue, decreasing the abilities of photosynthesis resulting in necrotic, chlorotic and dead of the infected leaves. In fruits, infection causes break in the net, immature and rotten flesh, decrease sweetness and scent in cultivar Action434, MAI and Ladika. Base on microscopic analysis, Powdery mildew isolat KP4 UGM is a member of from genus Podosphaera.

Abstract

Echinoderms have specific characteristic in the form of spines or protrusions on its body surface. The class of Echinoidea or commonly known as sea urchin is one of the extant members of Echinoderms with ecologically and economic pivotal roles. Habitat of sea urchin is a hard bottom with a mixture of coral reef ecosystems, seagrass beds, and sand and coral debris. In the area of Sari Ringgung Beach, coral reefs and seagrass ecosystems are quite extensive. The purpose of this study was to investigate sea urchin species and analyze its population, relative abundance, diversity index, and dominance index. This research used purposive sampling method based on substrate type criteria. The sea urchin found were identified using the Clark & Rowe (1971) identification book. Two species of sea urchin were found and identified as Diadema sp. and Brissus sp. Individual abundance values ranged from 0-0.027 ind/m2, relative abundance values ranged from 0-96.67%, sea urchin species diversity index was low, ranging from 0-0.5982, and was dominated by sea urchin types of Diadema sp. at station 2 of 0.9356

Abstract

The implementation of high-quality learning is something teachers must ensure. Consequently, teachers need to be able to design engaging learning procedures that draw students' attention to the subjects they are teaching. Understanding a student's preferred learning style is one of the necessary teachers. People with learning styles closely tied to their environments and personalities are adjusted. The process of receiving knowledge will be improved by defining the learning material to the learner's preferred learning style. One of the most used diagnostic tools for determining learning type is the VARK model. The visual, Auditory, Read/Write, and kinesthetic learning styles are divided into four divisions in the VARK paradigm. This research aims to identify the dominant learning style among science students. A qualitative descriptive methodology used one hundred junior high school students as research participants. Diagnostic exams and interviews were the tools used. Data analysis was carried out qualitatively by reducing data, presenting data, and making conclusions. According to the findings, 35% of students are kinesthetic learners, with 30% being visual, 21% being Auditory, and 14%t being Read/Write. Identifying learning tools, such as choosing learning models, creating and choosing materials, and learning media and assessment approaches that are more effective in accordance with student learning styles, can be done by developing one's understanding of learning styles.
