Abstract

The mealybug insect pest planococcus spp. (Hemiptera: Pseudococcidae) attacks most plants, including food, horticultural, and plantation crops, which directly impacts reducing yields. Continuous control using pesticides made from synthetic chemicals harms environmental sustainability. The use of the entomopathogenic fungus Beauveria bassiana as a pest control for Planococcus spp. can be a long-term, environmentally friendly solution. The Beauveria bassiana fungus can kill all insect stages of various plant pests from all insect pest orders. The efficacy of beauveria bassiana is influenced by various types of enzymes from the secondary metabolites produced, namely: chitinase, protease, amylase, and lipase which function as degraders of the insect integument layer. Efficacy is also influenced by the production of toxins consisting of beauvericin, bassianin, bassiacridin, beauvericin, bassianolide, cyclosporine, oosporein, and tenellin which disrupt the nervous system and kill target insects. The results showed that the application of the Beauveria bassiana fungus was effective in reducing the population of the pest Planococcus spp. and reducing plant damage. The Beauveria bassiana mushroom is an alternative substitute for pesticides made from synthetic chemicals and is very prospective to be used as a biopesticide in controlling the pest Planococcus spp. which attacks agricultural plants and plantations.

Abstract

Anura relies on habitats that are still preserved for its survival. The Bukit Baka Bukit Raya National Park offers natural and well-preserved habitats that support the survival of Anura. Data on the composition of Anura species are crucial for a conservation area, as the diversity of Anura is one of the parameters for maintaining the balance and sustainability of the ecosystem in the area and the environmental quality around it. However, there is no available data on the composition of Anura at Belaban Resort. This study aims to examine the composition of Anura in three habitat types at Belaban Resort, Bukit Baka Bukit Raya National Park. The method used in this study was a Visual Encounter Survey (VES) along the river at three locations, conducted from 18:00 to 22:00 WIB. The data obtained were analyzed descriptively, including the number of families, the number of species, the number of individuals, and environmental factors. The composition of Anura found consists of 13 species from 7 genera and 5 families, with a total of 234 individuals. The most commonly found family is Ranidae, and the most frequently encountered species is Fejervarya cancrivora, while the least numerous are Kalophrynus meizon and Leptobrachella hamidi. The conservation status of Meristogenys jerboa is vulnerable.

Abstract

Toll-like Receptors (TLRs) genes are a group of genes that transcribe TLRs proteins which act as receptors on the surface of phagocytic cells to recognize molecular patterns of pathogenic microbial components. This research aims to identify the variability of the TLR4 gene and its relationship with blood profiles in local Indonesian chickens. The samples used to identify TLR4 gene diversity in local Indonesian chickens were 135 samples. Research methods include DNA extraction, PCR amplification, RFLP analysis, and genotype determination. The genotyping results in the research were associated with a complete blood profile so that a genotype was obtained that could be used as a marker for resistance traits based on the blood profile. The results of this study showed that the TLR4 gene was polymorphic with three genotype types and an allele frequency of more than 0.01 in each KUB, Sensi, and Broiler CP 707 chicken. The frequency of the GG genotype is the highest compared to the AG and AA genotypes. White blood cell concentration values showed variations in the three genotypes of TLR4 gene and were still within normal standards, although statistically the differences were not significant.

Abstract

Ecoenzyme is a fermented liquid product containing lactic acid bacteria in fruits and vegetables. Nutrients derived from ecoenzymes such as nitrogen are used for growth. This study evaluated the effect of ecoenzyme administration on the number of Trichoderma asperellum spores in brown glutinous rice medium. Trichoderma asperellum is known as a beneficial fungus in the decomposition of solid waste and the enhancement of plant growth. The use of medium made from brown glutinous rice was tested as an alternative to Potato Dextrose Agar (PDA), with the addition of ecoenzyme as an additional nutrient. This study used a Complete Randomized Design (RAL) with six treatments and five repeats. The treatment given is the addition of ecoenzyme concentrations of 0%, 20%, 40%, 60%, 80%, and 100%. Data was analyzed using fingerprints and follow-up tests with DNMRT at an error rate of 5%. Observation of the number of spores is carried out at the age of 60 days by dilution and hemasitometer. The results showed that the 60% ecoenzyme concentration had the highest average spore count and was different from the 0% control. In contrast, the 20% concentration had the lowest average and was the same as the controls. Giving ecoenzyme to brown glutinous rice medium can increase the number of Trichoderma asperellum spores.

Abstract

Bagek Kembar Essential Ecosystem (BKEE) is one of the mangrove ecosystem areas located in Cendi Menik Village, Sekotong. West Lombok. The Bagek Kembar mangrove ecosystem is designated as an Essential Ecosystem Area which can be used by the community as a place for catching crabs, shellfish, shrimp and fish incluiri for ecotourism activities. Research on biometrics of blood clams aims to analyze the body biometric distribution of blood clams in the BKEE. Blood clams were taken in the Bagek Kembar Mangrove Ecosystem Area, with a total of 186 individuals at each station. Blood clams were  measured on their body parts, namely: shell length, shell width, shell height and weight. The research results showed that the biometrics of the blood clams caught were 12-52 mm long, 10-41 mm wide, 14-54 mm high and 3.5-10.5 grams weight. Judging from the distribution of lengths, the blood clams caught have not yet reached a suitable size for catching because they were dominated by the sizes of under 40 mm (146 individuals), where the suitable size for catching should have a shell size at least 40 mm. Meanwhile, width and height always follow the length, where the length increases. width and height also increase. Meanwhile, the weight distribution has reached the catchable size category with large size of 9.5-10.5 grams as many as 32 individuals.
