Abstract

This study aimed to compare and determine the hatchability inhibition of the tree sorrel extract (Averrhoa bilimbi L.) and snake plant as natural ovicide of apple snail (Pomacea canaliculata L.). This study employed the completely randomized design (CRD). The negative controls were the extracts with the concentrations of 1%, 1.5%, 2%, 2.5%, 3%, and a positive control. Data analysis used was one-way ANOVA and then continued by Least Significant Difference (LSD) test. The results showed that tree sorrel extract with 3% concentration had the highest inhibitory on the hatchability of apple snail eggs compared to the snake plant extract (Sansevieria trifasciata P.) with a comparison value of 19.47%. Perbandingandaya Hambat Tetas Telur Keong Mas dari Buah Belimbing Wuluh dan Daun Lidah MertuaAbstrak: Tujuan penelitian ini untuk membandingkan dan mengetahui daya hambat tetas telur keong mas dari ekstrak buah belimbing wuluh (Averrhoa bilimbi L.) dan daun lidah mertua sebagai ovisida alami keong mas (Pomacea canaliculata L.).

Abstract

This study aims to isolate and determine the antagonistic activity of lime's endophytic mushrooms on Candida albicans. Antagonism tests were performed in vitro with dual culture methods. The study obtained 14 isolates that were successfully isolated from the stem, roots, leaves, and peels of lime fruit. A total of 8 isolates could inhibit Candida albicans through antibiosis mechanisms and healthy competition. The isolates with the highest inhibition percentage were KD2 and MA1 (42.85%).

Abstract

Organic waste produced by economic activities may create health, aesthetic, and economic problems. One of the approaches applied to solve this problem is the utilization of decomposer macrofauna to decompose the waste. One of the decomposers with great potential is Black Soldier Fly larvae (Hermetia illucens) that can consume various types of organic wastes and converts it into biomass with high protein and lipid content. In this study, banana peels and coconut testa had been fed to the larvae at 200 mg/larvae/day as the objects that represented organic wastes with low fiber content and high fiber content respectively. The purpose of this study was to observe the growth and efficiency of BSF larvae in decomposing those wastes. The analysis was conducted on some parameters such as the growth and consumption rate, the efficiency of conversion of digested (ECD), waste reduction index, and mortality rate. The results showed that BSF larvae THAT consumed banana peel had a higher final weight (58.24 mg), growth rate, and consumption rate while the mortality rate was lower than BSF larvae that consumed coconut testa. The ECD of the larvae group that consumed banana peel was higher than the larvae group that consumed coconut testa. The waste reduction index of banana peel was higher than coconut testa (1.5 and 1.4, respectively). The larvae that consumed coconut testa had a longer pupation period (9±1,75 days) compared to the larvae that consumed banana peel. Based on this result, it can be concluded that the fiber content of organic waste affected the decomposition rate and growth of BSF larvae.

Abstract

Learning resources need to be developed based on current developments. The purpose of this research was to develop an Islamic-based Botanical Encyclopedia and test its quality. The method used to develop the encyclopedia was Research and Development (R&D) with the 4D model (Design, Define, Develop, and Disseminate) proposed by Thiagarajan in 1974 as the development model. The research instrument had been validated by the material, media, and integration experts. The average percentage of the validation result was 88% (a very valid category). The small-scale trial obtained a percentage of 89% (very valid), and the large-scale trial obtained a percentage of 85% (very feasible category). The results indicated that the developed Islamic-based Botanical encyclopedia could be used as a resource for independent learning.

Abstract

Billygoat weed (Ageratum conyzoides) is mainly used to treat wounds and fever. People also do not understand the use of these leaves in the treatment to increase the platelet counts. The objectives of this research Objectives were to test whether the Billygoat Weed’s leaves can increase platelet count of male mice and to find out what is the most effective dose of the Billygoat Weed on the platelet count of male mice. This research was done by employing the true experimental approach with the completely randomized design which consisted of 5 treatments, namely the negative control (plain water), the positive control (acetylsalicylic acid), 1.68 mg/kgBW, 2.52 mg/kgBW, and 3.36 mg/kgBW on five mice in each treatment. The increase in the platelet counts, based on the results of One-Way ANOVA with a p-value of 0,0004, the Billygoat Weed extract was able to increase the platelet counts. Through further testing, the smallest significant difference showed that a dose of 3.36 mg/kgBW was effectively able to increase the platelet counts of male mice with an average of 11140.80/.

Abstract

This study aims to isolate and identify LABs that spontaneously grow fermented cocoa beans that have the potential as probiotics. The isolation was carried out selectively using an MRS agar medium supplemented with 1% CaCO3. LAB's potential as a probiotic was selected based on the acid resistance test, bile salt resistance test, and antimicrobial activity test. The results showed that three isolates of lactic acid bacteria, namely strains K1B1, K2T2, and K3B4 were tolerant of gastric acid's pH conditions (pH 2.5, pH 3, and pH 4). They also can survive the bile salts (0.3%, 0, 5%, and 1%) and have antibacterial characteristics. The three isolates were identified as Lactobacillus Plantarum species (ID 99.9%).

Abstract

Soursop leaf tea is a health drink that contains steroid compounds, terpenoids, flavonoids, kumari, tannins, and alkaloids. The flavonoids and tannins in soursop leaves act as antioxidants. Since it has an unpleasant aroma, cinnamon is added to add scent and flavor. This study aimed to determine the effect of cinnamon powder on the soursop leaf tea's antioxidant activity. This study employed the completely randomized design method (CRD) with two factors: the soursop leaves and cinnamon powder concentrations. This study consisted of four treatments, namely SP0 (100% soursop leaves), SP1 (90% soursop leaves and 10% cinnamon powder), SP2 (80% soursop leaves and 20% cinnamon powder), and SP3 (70% soursop leaves and 30% cinnamon powder) within three repetitions. The proximate test was focused on antioxidant activity analyzed by ANOVA at α = 5%. The organoleptic test covered the color, taste, aroma, and other overall preferences by qualitative descriptive tests. The results showed that the highest antioxidant (29.19%) could be found in the SP3 sample (70% soursop leaves and 30% cinnamon powder), while the preferred organoleptic test was the SP2 sample.

Abstract

This study aims to analyze students' environmental care character and the obstacles faced by the Adiwiyata school. This study employed the descriptive qualitative method with the case study approach. The researchers analyzed the students' environmental care character with the Adiwiyata program, specifically SMAN 1 Dukuntang. In the aspect of classroom hygiene management, the school was in the very good category. Next, in the environmental education management aspect, the school was also in the very good category. The school also foster students' creativity through the DLS program by creating environmentally friendly products with economic value. The obstacle faced by the Adiwiyata school in shaping the students'  environmental care character was the need for free time for students to participate in environmental activities outside of school during the implementation of the SBL program.
