Abstract

The main environmental problem today is still about pollution. Residential settlements always produce waste, especially household liquid waste. This type of waste is generally in the form of water that is cloudy in color and emits an unpleasant odor. This type of liquid waste is known as greywater. The direct impact of pollution is the contamination of groundwater (wells) and river water by greywater. As a result, the quality of the environment is getting disturbed. Especially in Angsau Village, Pelaihari Sub-district, Tanah Laut Regency, the majority of the population uses well water for bathing and washing toilets (MCK) and cooking. The purpose of this research is to reduce phosphate levels in greywater wastewater more effectively and efficiently. This type of research is a true experiment with a pretest-posttest research design with a control group design. The subject of the research was household liquid waste (greywater) which was taken at random in Angsau Village, Pelaihari District, Tanah Laut Regency, South Kalimantan Province. The study was designed with 6 treatments, namely variations of activated carbon used in two constructed wetlands reactor tanks. The first reactor uses coconut shell activated carbon, and the second reactor uses palm shell activated carbon. The results showed that, the thicker the activated carbon applied to the constructed wetlands reactor system, the lower the phosphate levels in household wastewater (greywater). The highest average percentage value was in the treatment with 15 cm thick activated carbon, and the lowest percentage mean value was in the treatment with 5 cm thick activated carbon. The results also showed that activated carbon from palm shells was more effective in reducing phosphate levels in household wastewater (greywater) compared to the use of activated carbon from coconut shells.

Abstract

Cayenne Pepper (Capsicum frutescens L.) is one of the horticultural crops that has the potential to be developed because of its high demand and role for consumption on a national scale and for export. Increasing the success of cultivation can be done by adding arbuscular mycorrhizal fungi (CMA). One of the CMA is Gigaspora sp. can be developed as a biological fertilizer agent because this fungus is a symbiotic mutualism. This study aims to determine the effect of the dose of CMA Gigaspora sp. against cayenne pepper plant nurseries. This study used a completely randomized design (CRD) with 4 treatments and 5 replications. The treatments included G0 (Gigaspora spores only), G1 (Gigaspora spores + 15 grams of propagule), G2 (Gigaspora spores + 30 grams of propagule), G3 (Gigaspora spores + 45 grams of propagule) and control (K). The observed variables were growth including plant height, number of leaves, total dry weight, and percentage of colonization of Gigaspora sp. on the root. The results showed that there was an interaction between CMA Gigaspora sp. in single form or with a mixture of propagules can increase the growth of cayenne pepper plants. The administration of a mixture of propagules was more effective than the administration of Gigaspora sp. as a single spore after 75 days. Optimal treatment for 4 parameters, namely G3 (Gigaspora spores + 45 grams of propagule) which showed a plant height of 89.24 cm, number of leaves 60.14 strands, total dry weight 10.27 grams, and the percentage of colonization of Gigasporasp on roots of 84, 62%.

Abstract

The development of guided inquiry-based worksheets is based on the lack of learning media in high school biology subjects that can help students think critically. The aim is to develop LKPD based on guided inquiry that is feasible, effective, and practical to help students improve their critical thinking skills. The method is the R&D model of Thiagarajan et al. (1974) namely 4D design, including: define, design, develop, and disseminate. The data analysis technique used is quantitative and qualitative. Quantitative data analysis is used to see the level of feasibility, practicality, and effectiveness. Meanwhile, qualitative data analysis is to find out comments, criticisms, suggestions, and observations. It was found that the guided inquiry-based LKPD that had been developed was feasible to be applied with a percentage of 100% (media expert), 89% (material expert), and 100% (language expert), and the LKPD was declared practical as seen from the achievement of the teacher response sheet with an average 100% and student response sheets with an average of 93.07%. LKPD was also declared effective as seen from the achievement of post-test completeness of 0.70 in the medium category. Based on the results above, it can be concluded that the guided inquiry-based worksheets that have been developed are declared feasible, practical, and effective to use, and can improve students' critical thinking skills.
