Waste processing, especially organic waste, which in practice is still not optimal in Indonesia. One method of processing organic waste is using eco enzymes, which are made by fermenting vegetable and fruit waste combined with water and sugar. The raw materials for making eco enzymes vary and have different characteristics so they have high potential to be used in various fields. This research aims to examine the properties of organoleptic eco enzymes their raw materials and their application to human requirements. This study used an experimental method by repeating twice for each raw material including vegetables, a mixture of fruit peels (mango, pineapple, durian), pineapple peel, banana peel, and orange peel. Then the eco enzyme data is analyzed for characteristics based on parameters such as color, aroma, taste, and pH. According to the findings, the eco enzyme has a distinct brown color that ranges from light brown to dark brown, the aroma and taste produced show from very sour and smelly to a slightly sour and characteristic smell, and than the pH levels range from 2.98 to 3.50. The characteristics that have been analyzed organoleptic in this study indicate that the eco enzymes produced are very good, namely brown color, sour aroma, slightly doormat taste, and a pH value of <4. Eco enzymes are used in various fields such as household needs as cleaning fluids, the environment as a wastewater purifier, health is used to improve well water quality, and agriculture as a fertilizer and plant disinfectants

Decreased water quality in red tilapia (Oreochromis niloticus) aquaculture indicates that low dissolved oxygen availability will affect fish behavior. One of the efforts to improve water quality is through the addition of aerators and filters. Aerators and filters increase the supply of dissolved oxygen and minimize feed waste in the aquaculture pond water. This study aims to analyze of different aeration and filtration or a combination of the daily behavior patterns of tilapia including eating behavior, aggressive behavior. The study was conducted for 1 month.This study used 24 red tilapia with a length of about 8-12 cm. The research design used in this study was a completely randomized design (CRD) with 4 treatment groups and 6 replications. The treatments were ANF group (use of single aerator without filter), AANF group (use of dual aerator without filter), AF group (use of single aerator with filter), and group AAF (use of dual aerator with filter). The data collected includes the daily behavior of red tilapia and water quality. Analysis of the daily eating, aggressive and comfortable behavior of red tilapia was carried out by observing video recordings and recording behavior recording techniques at intervals of 1-2 minutes based on duration and frequency. The results showed that the use of different aerators and filters or their combination had a significantly different effect (P<0,05) on the daily behavior of red tilapia. The conclusion of this study was the raising used of multiple aerators and filters can improve the quality of aquaculture water so that it has a positive impact on feeding, foraging, and schooling behavior in the growth phase of tilapia. Key words: quality water, aerator, filterd, aily behavior

This study aims to determine the effect of air pollution on the stomata characteristics in Pigeon Orchid (Dendrobium crumenatum) leaves in Tasikmalaya. This research is quantitative. The Samples were taken through survey method with purposive sampling technique in the Singaparna Bus Station as an exposed area with the highest air pollution, Sukaraja-Mangunreja street as an exposed area with the moderate air pollution, and Mount Galunggung as an exposed area with the the lowest air pollution. The characteristics of the stomata observed using an Optilab camera type Professional Model Series MTN001 which already has the Image Raster application and previously calibrated with an object glass micrometer at 400 x magnifications. The Data analysed quantitatively and descriptively using one way ANOVA test. The results showed that different levels of air pollution could affect the characteristics of the stomata. Stomata in areas with high air pollution have the highest stomata index and stomata density, namely 8.2% and 326.11/mm2, with the category of medium density and oval stomata shape. Stomata in areas with moderate air pollution have the lower stomata index and stomata density, namely 7.3% and 256.47/mm2, with the low-density category and round stomata shape. Meanwhile, stomata in areas with low air pollution have the lowest stomata index and stomata density, namely 5.7% and 256.47/mm2, which indicate the category of low density and the shape of the stomata is round.

Prevention of environmental damage can be done by recycling household waste both organic and inorganic. One of them is by making eco-enzymes made from banana peel waste which is found in the environment. This study aims to determine the level of respondents' liking based on organoleptic test variables. This research method is an experiment that includes making eco-enzymes, and organoleptic tests consisting of aroma, color and texture variables. Data analysis was carried out in a qualitative descriptive way by looking at the level of respondents' liking. The results showed that the average respondent chose a brown color with a percentage of 90%, yellow 7%, and colorless 3%. The scent variable respondents chose sour odor by 70% and other aromas 30%. While the texture of all respondents chose the composition of liquid eco-enzyme. This is due to the metabolic activity of microorganisms that result in the breakdown of substrates by bacteria resulting in changes in the aroma, color and texture of banana peels. The conclusion of this study is that the use of banana peel as the basic ingredient for making eco-enzyme affects the respondents' level of liking. Eco-enzyme can be used as a natural fertilizer for plant growth and can reduce household waste.

Bacillus spp. (NrLtF1, NrLtF5, and NrLtG2) isolated from the digestive tract of the Nypa palm worm (Namalycastis rhodochorde) were assumed to have growth characteristics according to the habitat conditions of the nypa worm. Nypa worms live in estuary environments that are affected by seawater intrusion. Salinity and pH are two environmental factors affecting gastrointestinal isolates' growth from nypa palm worms. This study aimed to determine the effect of pH and salinity on the media on growth patterns and determine the optimum combination of pH and salinity for Bacillus spp. The study was conducted using a spectrophotometry method using a microplate reader with Glucose Yeast Peptone (GYP) as a medium for bacterial growth. The medium's pH and salinity values were adjusted by adding 5M NaOH and 5M HCl to obtain pH values of 4, 5, 6, and 7, respectively. Addition of NaCl to the growing medium to get salinity values of 5%, 10%, and 15%. Optimization was determined by incubation at a density of 595 nm at a temperature of 31oC for 24 hours. The results showed that Bacillus spp. could grow well at pH 6 with a salinity value of 15%, pH 6 with a salinity value of 10%, and pH 6 with a salinity value of 5% based on contour plot design. The Optimum growth of Bacillus spp. with pH and salinity expects to be a reference for developing feed products based on indigenous nypa palm worms.

The use of media through the Android application is still limited, even though it is needed to foster interest in learning after the COVID-19 pandemic. The research focused on increasing learning interest through the application of the Android-based Word Square learning media. This experimental research used a pretest-posttest control group design. The population in this study were all students of class IX MTs Guppi Samata, which consisted of 2 classes. The saturated sampling method was used in the sampling procedure with six samples taken from the experimental class IX-A and six samples taken from the control class IX-B. The research instrument was a questionnaire consisting of 30 items. The data analysis technique used the Wilcoxon signed ranks test. Students' learning interests differed depending on whether or not they used the Android-based Word Square learning media (p = 0.046, p 0.05). The results showed the differences in students' interest in learning with and without using the media of Word Square learning media based on android human reproductive system material for class IX MTs Guppi Samata (p = 0.046, p < 0.05). The average interest in learning among students through the media was 114.83. The value was higher than those without using the media (106.50). This proves that Word Square learning resources based on Android can increase students' learning interests. The findings of this study can be used to inform teachers' decisions about how to use engaging learning technologies and a variety of media to enhance the quality of their instruction.

The use of student’s worksheets as teaching materials and supporting learning activities is still not evenly distributed. The components are sometimes incomplete. This study aims to describe the development and determine the feasibility of guided inquiry-based worksheets as teaching materials for the endocrine system sub material for second-grade of high schools. This study used a 4D development model limited to three defining, designing, and developing stages. The student’s worksheets were designed based on the problems obtained from interviews with biology teachers in three different schools. At the development stage, the worksheets were validated by five validators consisting of two lecturers and three biology teachers in Pontianak. The validation assessment contained four aspects: the feasibility of the content/material, language, presentation, and graphics with 19 criteria. The student’s worksheet was successfully developed with enrichment in the form of discourse analysis activities related to diabetes and the process of lowering blood sugar levels by plant extracts with guided inquiry stages. The feasibility analysis results of the guided inquiry-based student’s worksheet obtained CVR and CVI values of 1 each so that product can be declared ready for the limited and extensive trial phase. However, the significance of the enrichment topics in this student’s worksheet still needs to be re-examined directly in the teaching and learning process in the Endocrine System Sub material for second grade of high school in both small and large scales groups.

Medicinal plants are used for various kinds of health care, one of which is to treat problems in the digestive system. This research aimed to analyze the utilization of family medicinal plants (TOGA) by the ethnic of Dayak Muara in Tanap village in handling digestive system disorders. This study was conducted by survey method with a purposive sampling technique. This research was initiated by conducting interviews with the people of Tanap village who came from the Dayak Muara, then continued with identifying the medicinal plants mentioned. The data obtained were then analyzed with an ethnobotanical index in the form of Use Value (UV), Informant Consensus Factor (ICF), and Fidelity Level (FL). The Dayak Muara ethnic in Tanap Village uses 22 species of TOGA to handle digestive system disorders. The highest families used were Zingiberaceae and Amaryllidaceae. The dominant plant parts used, processing method, administration method, and remedies form for the handling of digestive system disorders are leaves (36%), boiled processing (43%), drinking (44%), and single herb form (67%). Plants with high use value (UV=1) are jambu biji (Psidium guajava) and kunyit (Curcuma longa). The digestive system disorder categories with the highest ICF included sprue (1), nausea and vomiting (0.98), intestinal worms, diarrhea, abdominal pain, and constipation (0.97). Plant that had the highest FL value (100%) included cocor bebek (Bryophyllum pinnatum), patah tulang (Euphorbia tirucalli), and putri malu (Mimosa pudica) for the treatment of toothache. Entawak (Artocarpus anisophyllus) for stomachache, pinang (Areca catechu) for constipation, lidah buaya (Aloe vera) for hemorrhoids, and sawo (Manilkara zapota) for stomachache.
