Macodes petola (Blume) Lindl. has an attractive of leaves veins motif with letters pattern, so it has a high economic value. Tissue culture technique is reported as the best way of plant propagation in short time. BAP (6-Benzyl Amino Purine) has a role in stimulating shoot growth with a certain concentration. The purpose of this study was to determine the effect of Various Concentration BAP (6-Benzyl Amino Purine) on Orchid Growth (M petola (Blume) Lindl.) in vitro. This study used a completely randomized design (CRD) with 4 concentration BAP levels (0; 0.5; 1; 1.5 ppm) with 3 replication. Based on the results of the study, it showed that up to 60 DAP (Day After Planting) the composition of the media with a concentration of 0 ppm BAP had a higher average value for the increase in the stem height, number of shoots and number of roots, namely 1.77±0.798 cm, 2.4 ± 1,528 shoot and 2.4 ± 2,082 root. In contrast to the concentration of 1.5 ppm at this concentration it has a low average value the parameters of stem height, number of shoots and number of roots.

Taman Hutan Raya (TAHURA) Ir. H. Djuanda Bandung is an integrated conservation area in which there are secondary natural forests that have various kinds of flora and fauna. Macrofungi are fungi whose fruiting bodies can be seen directly without the aid of a microscope, heterotrophic, and ecologically act as decomposers of organic matter (decomposers) and as biological control agents. Data related to research results on macrofungi in the Tahura area is still limited and need more comprehensive research. This study aimed to inventory, determine the growth factors, and potential utilization of macroscopic fungi. Observations were carried out during the period of November 2021 - April 2022 using exploration method. Sampling was done by purposive sampling method. Macrofungi identification process was carried out based on morphological characters such as cap, stalk, and lamella, The environmental factors observed included air humidity, soil pH, temperature, and type of substrate. The results showed that as many as 83 species were found in the Protection block, 50 species were found in the Collection block, and 99 species were identified in the Utilization block from the phyla Basidiomycota and Ascomycota. The macrofungi found have potential as biodegradation agents, food ingredients, non-food ingredients, drugs, antimicrobials, antioxidants, anticancer, and anti-inflammatory.

Arumanis is one of the cultivars of Indonesian mangoes used as a horticultural commodity. Young leaves arumanis can be used for traditional herbal medicine. Pharmacological activity of young leaf arumanis extract are known to be antidiabetic, anticancer, antibacterial, anti-inflammatory, and analgesic effects. However, it is necessary to carry out toxicity testing before young leaf arumanis extract is used in traditional herbal medicine. This study aimed to determine the LC50 value of young leaf arumanis extract and identify the hatching time of embryos, heart rate of larvae, swimming movement of larvae, and malformations in both embryos and larvae. Forty five embryos of zebrafish were exposed to several concentrations of young leaf arumanis extract at 24 h post-fertilization until 96 h post-fertilization. Percentage of embryonic death calculated using probit analysis model LC50. Hatching rate, swimming movements, and heart rate were analyzed using the IBM SPSS software version 26. The LC50 values of the young leaf arumanis extract were 42.65μg/mL at 96 hpf and also 42.65μg/mL at 72 hpf. The embryotoxic effects at high concentrations of the extract are hatching delay and decreasing heart rate. The extract also caused abnormalities in embryo morphology, including pericardial edema and tail bending.

Sanghyang Kenit Cave is a cave that has an aquatic environment and a potential habitat for plankton. Plankton can be a bioindicator of water because of its sensitivity to the environment. The purpose of this study was to determine the diversity, interrelationship factors, and linkages of plankton with the environment in the waters of Sanghyang Kenit Rajamandala Cave, West Bandung. This research was conducted from August 2021 to September 2022. The study employed a purposive sampling method, identifying three sampling zones (The Light, Twilight, and Dark zones) during morning, afternoon, and evening periods. Sampling was done by taking a sample of 10 liters and then filtering using plankton net. The Physico-chemical parameters measured included water temperature, light intensity, pH, DO, salinity, nitrate, and phosphate. Based on the results of data analysis found 4 classes with 12 plankton morphospecies. Diversity index values in the Light zone (1.10), Twilight zone (1.08), and dark zone (1.08). Abundance index value in the light zone is 2.537 cells/l, the twilight zone is 501 cells/l, and the dark zone is 29 cells/l. Diversity and plankton in the waters of Sanghyang Kenit Cave have a very strong correlation with water temperature, light intensity, and pH of water. This can be the basis for the development of further research on the management and monitoring of caves that are used as tourist attractions.KeywordsDiversityPlanktonSanghyang Kenit CaveEnvironment

Zebrafish (Danio rerio) is one of the model animals in cell regeneration studies because it has a high ability to regenerate tissue structures, one of which is its caudal fin. This study was conducted to determine the different light interventions on the regeneration of the caudal fin of zebrafish. The research method used is an experimental study with the observed parameters, including specific growth, absolute weight gain, length increase, and survival. A total of 28 male wild-type zebrafish were used in this study at the age of 3 months. The amputated zebrafish on its caudal fin was placed at different light intensities (control, 0 lux, 60 lux, and 90 lux). Parameter measurements were carried out every two days. ANOVA analyzed the data obtained with a significance level of 95%. The results showed that at a light intensity of 90 lux, the zebrafish tail fin regeneration was the most significant based on an increase in total length of 0.10 mm. Using a light intensity of 90 lux is the best condition in the regeneration process of the zebrafish caudal fin. The research findings could be further applied in the healing process of external wounds.

Indigenous bacteria found in natural environments, such as tofu waste, are strongly influenced by environmental factors and environmental nutrients. The purpose of this study was to determine the effect of tofu waste nutrients on the number of indigenous bacteria in tofu waste. The parameters observed were the characteristics of tofu waste, such as color, aroma, acidity level (pH), and analysis of nutrient content through proximate tests, as well as the calculation of the number of indigenous bacteria using the Total Plate Count method. The results showed that tofu waste was yellowish in color and had a soy aroma, but there was a slight sour aroma in tofu liquid waste. Tofu solid waste had a pH of 6, while tofu liquid waste had a pH of 5. The levels of nutrients, namely protein, fat, ash, and carbohydrates, were higher in tofu solid waste, while the water content was higher in tofu liquid waste. The total indigenous bacteria in tofu solid waste were higher (3.78 × 106 CFU/mL) than in tofu liquid waste (5.55 × 105 CFU/mL). This study concluded that high nutrient content correlated with an increase in the number of indigenous bacteria in tofu waste.
