Abstract

Improving the achievement of competencies which are indicators in the study of the quality of education in Indonesia, can be done by procuring quality and innovative teaching materials. This study aims to develop a science learning handout on the human digestive system to improve critical thinking skills for class VIII SMP. Development is done by (Educational Design Research). This study aims to develop a science learning handout on the human digestive system to improve critical thinking skills for class VIII SMP. This article describes the results of the validity and practicality of science learning handouts on the human digestive system. The instrument used in this study was a validity and practicality questionnaire. Data analysis techniques include descriptive data analysis, validation sheets, and questionnaires. The handout validation sheet is given to 5 validators. Instead, 31 grade VIII students of SMP Negeri 5 Banjarmasin were given practice sheets. The results of the validity questionnaire analysis concluded that the validity of the handout was 3.67 very valid categories. Practicality test of content average of 87.41 was obtained in the very practical category. The results of the practicality test of expectations average of 87.78 in the very practical category. Finally, the actual practicality test results average of 85.65 with a very practical category. This means that science handouts are valid and practical in the learning process to practice critical thinking skills

Abstract

Serpentine soil contains highly heavy metals, such as manganese, chromium, cobalt, and nickel,which could bean inappropriate growthmediaofmostplants. Someplants thatfound able to grow optimally on South Kalimantan serpentine soil have been known to do association with ectomycorrhizal fungi. This research aimed to obtain and characterize mushrooms assumed as ectomycorrhizal fungi indigenous South Kalimantan serpentine soil. This study used field exploration of fungal fruiting bodies and identified the genus based on morphological characters of fruiting bodies such as shape, size, and ornamentation, which are unique for the genus identification, then compared the characteristics on mushroomexpert.com. The mushrooms were also confirmed of genera assumed as ectomycorrhizal fungi based on mycorrhizas.info. Seven fruiting bodies were obtained and classified as Cantharellus (Ct), Chlorophyllum (Ch1 and Ch2), Lycoperdon (Ly), Ramaria (Rm1 and Rm2), and Thelephora (Tp). The results showed that all of those fruiting bodies belong to Basidiomycetes. There were 4 genera of Cantharellus, Lycoperdon, Ramaria, and Thelephora, assumed as ectomycorrhizal fungi. But Chlorophyllum genus was never reported as ectomycorrhizal fungus

Abstract

The proboscis monkey's habitat is a mangrove area dominated by rambai (Sonneratia caseolaris) as their main food source. In order to suppress the rate of decline in the proboscis monkey population due to habitat loss, it is necessary to restore proboscis monkey habitat by planting rambai mangroves in their natural habitat areas, such as Curiak Island, to increase the carrying capacity of feed. So far, the rambai tree planting activity on Curiak Island is still being carried out on a self-taught basis by partners. So, there are still obstacles such as the low survival rate of seedlings, slow growth rates, challenges in transferring seedlings to planting sites, and pests and plant diseases that interfere with the growth of rambai mangroves. In this program, it has been conducted the introduction of Composter as a tool for processing organic waste into fertilizer to assist the seedling process, so that the survival of the seeds increases. Partners are also given training and counseling on the Rambai Mangrove Restoration technique with assistance starting from seed selection, transportation of seeds to planting sites, planting, and maintenance. A total of 2 composter barrels and 100 rambai mangrove seedlings have been planted with partners on Curiak Island. After this program, partners are judged to have been able to absorb the science and technology transferred by the team with an in the success of planting rambai mangroves at the planting location, Curiak Island. In future, partners are expected to independently carry out a sustainable rambai planting program so that efforts to restore proboscis monkey habitat and conserve river ecosystems can be realized.

Abstract

This study aims to develop student worksheets based on critical thinking skills for seventh-grade students in junior high school. Development is carried out by means of Education Design Research (EDR). This article describes the results of the validity and practicality of worksheets based on critical thinking skills. The data collection technique used is a test questionnaire. The instruments used in this study were students' validity and practicality questionnaires. Data analysis techniques include analysis of data validity, data, and practicality (practical content, expectations, and actual). The worksheets validation sheet based on critical thinking skills was given to 5 validators consisting of 3 education experts and 2 science teachers in public junior high school 12 Banjarmasin. Three students filled out the questionnaire on the practicality of the contents of the worksheets through the one to one evaluation test, nine students filled out the practicality of the expectations of the worksheets through the small group evaluation test, and thirty-two students of the developed worksheets filled out the actual practicality of the worksheets. The results of the analysis of the validity of the questionnaire concluded that the validity of the worksheets was 3.60 valid categories. The results of the practicality of the contents are 3.84 in the practical category, the practicality of hope is 95.90 in the practical category, and the actual practicality is 96.06 in the practical category. This means that the worksheets based on critical thinking skills are valid and practical in the learning process to practice critical thinking skills
