Abstract

The use of biological agents is an effective way to prevent the negative impacts of excessive synthetic chemical pesticide use. Trichoderma sp., a saprophytic fungus, acts as a biocontrol agent against various phytopathogenic molds and is more commonly found in rooted soil and leaves than in stems or fruits. This study aims to identify the characteristics and presence of Trichoderma sp. in horticultural land using the baiting method. Isolation was carried out by collecting fungi grown on rice, corn, and coconut bait using an inoculation needle. Three Trichoderma sp. isolates were obtained from chili and bamboo root soil using rice and corn bait. The results showed that the three isolates had similar characteristics: colonies were dark green, circular in shape, powdery in texture, and had entire margins. Microscopically, the isolates featured branched and upright conidiophores arranged vertically, short and thick phialides, round greenish conidia, and septate hyphae resembling threads.

Abstract

This study aims to develop a peel-off gel mask formulated from orange peel eco-enzyme solution and its physical characteristics and antibacterial activity against Staphylococcus epidermidis. The resulting gel mask has organoleptic characteristics of transparent brownish color, thick gel consistency, and fresh sour-sweet aroma. Physical characteristic tests showed that the gel mask meets pharmaceutical requirements, namely: pH value 4.5-6.5, spreadability 5-7 cm, and drying time 15-30 minutes. The mask showed good homogeneity without aggregates, although it was a little difficult to peel off, but it was not easily torn, and had stable thermodynamic stability. Antibacterial tests revealed that the peel-off gel mask made from orange peel eco-enzyme was effective in inhibiting the growth of Staphylococcus epidermidis. The diameters of the inhibition zones of the P1, P2, and P3 masks were 2.5 ± 0.5 mm, 2.1 ± 0.35 mm, and 1.5 ± 0.5 mm, respectively. These results indicate the potential of eco-enzymes from orange peel as active ingredients for peel-off gel mask formulation for skin care, especially in inhibiting acne-causing bacteria.

Abstract

Mackerel tuna (Euthynnus affinis) is a significant fishery commodity in the Banda Sea, part of Fisheries Management Area 714 (WPP 714). This study focused on analyzing the biological characteristics of mackerel tuna, including length-frequency distribution, recruitment patterns, growth parameters, and mortality rates. Research was conducted at the Kendari Ocean Fisheries Port (PPS), with catch data from the Banda Sea provided by PPS Kendari observers. Data were analyzed using Microsoft Excel and software applying Von Bertalanffy's growth model. Fish length increased throughout the year, with the highest frequency observed from April to May and an average length of 50 cm. Recruitment patterns revealed two annual peaks in March and August. The growth constant (K) was 0.632, with a growth index of 1.0. Mortality analysis showed total mortality (Z) at 6.70, natural mortality (M) at 1.24, fishing mortality (F) at 5.46, and an exploitation rate (E) of 0.82. These results suggest that while growth rates remain favorable, mackerel tuna is experiencing overexploitation, highlighting the need for sustainable fisheries management.

Abstract

One of the roles of microorganisms is as a biological agent. This study aims to explore and identify the biological agent of the fungus Gliocladium sp. found in the rhizosphere of tomato plants. Exploration was done by taking samples of tomato plant root soil in five locations using a diagonal plot. Rhizosphere microorganisms were isolated using the multilevel dilution and spread on PDA media added with chloramphenicol. Fungal isolates were identified macroscopically and microscopically. The results of exploring fungal biological agents in the rhizosphere soil of tomato plants revealed four genera of fungal isolates, namely Aspergillus, Trichoderma, Paecilomyces, and Gliocladium. Based on the identification results, the fungal isolate Gliocladium sp. has a blackish-green colony color with a circular colony. In contrast, microscopically, it has the morphological characteristics of upright conidiophores, growing straight, and branching.

Abstract

Organic waste, often considered useless material, can be processed into value-added products such as eco-enzymes. Eco-enzyme is a liquid fermented from organic waste that contains various enzymes, including proteases. This study aims to explore the potential of proteolytic bacteria from eco-enzyme solutions made from vegetable and fruit waste and analyze the proteolytic index of the isolates obtained. This research applied a quantitative approach with descriptive methods. The isolation technique used in this research is the pour plate method with milk agar media, which calculates the number of bacterial colonies using the TPC (Total Plate Count) formula. The results showed that nine bacterial isolates were obtained from the isolation of vegetable and fruit waste-based eco-enzyme solution. Qualitative tests showed that isolate 8A had the highest proteolytic index of 5, while isolate 7B had the lowest proteolytic index of 1.5.

Abstract

Dengue fever is one of the viral diseases transmitted through arthropods and is still a significant health problem worldwide. Dengue virus is transmitted by Aedes aegypti mosquitoes from one human to another through blood sucking. These mosquitoes usually live and lay eggs in habitats close to stagnant water. The usual efforts to control Ae. aegypti are using natural and synthetic chemicals. Compounds to control Ae. aegypti eggs are called ovicides. One of the natural ingredients that is thought to contain natural chemicals that have the potential to be used as an ovicide is cherry leaves (Muntingia calabura L.). This study aims to determine the potential of the ethanol extract of cherry leaves (M. calabura L.) as an ovicide against Ae. aegypti. Five treatments and four replications were used. The results of this study indicate that the ethanol extract of cherry leaves (M. calabura L.) can potentially be an insecticide for Ae. aegypti at a concentration of 1% and an exposure time of 72 hours.

Abstract

Ectoparasites can infect aquatic biota, including spiny lobster (Panulirus homarus), which causes failure of spiny lobster cultivation, such as death, bacterial infection, and decreased cultivation quality. One of the failures of spiny lobster cultivation is often caused by ectoparasite disorders. Environmental conditions influence the growth and distribution of ectoparasites. This study aims to identify the types of ectoparasites and factors that influence the presence of ectoparasites in spiny lobsters and determine the intensity and dominance of spiny lobster ectoparasites. The study was conducted in floating net cages (KJA). It controlled Lampung Marine Aquaculture Center (BBPBL) tanks by purposive random sampling with 18 spiny lobsters, each taken from KJA and controlled tanks. The stages of the study included taking mucus samples on the tail and swimming legs (pleopods), microscopic examination of ectoparasites, calculating the intensity and dominance of ectoparasites, and measuring water quality parameters. The study results obtained three ectoparasites infecting the Spiny lobster, including the Protozoa phylum and the Ciliata class: Vorticella sp., Zoothamnium sp., and Epistylis sp. The intensity of Vorticella sp. ectoparasite attacks was 11.5/lobster. The most dominant ectoparasite was the Vorticella sp. type at 53.90%. The difference in the number of ectoparasites in controlled tanks and floating net cages was due to differences in temperature, size of the cultivation container, and depth, which affected water quality.

Abstract

This study aimed to measure substrate consumption and waste reduction index of edamame soybean using Black Soldier Fly (BSF) larvae as a bioconversion agent. This study used a Completely Randomized Design (CRD) with three treatments: unfermented edamame soybean waste (F0), fermented for 7 days (F7), and fermented for 14 days (F14). The observed bioconversions included substrate consumption and waste reduction index (WRI). Data analysis used analysis of variance with a confidence level of 5%. The results showed that waste fermentation significantly affected substrate consumption and waste reduction index. The highest average substrate consumption was obtained in treatment F14 (57.96±7.37), followed by F7 (41.61±6.73) and F0 (28.51±4.97). Likewise, with the waste reduction index, the F14 treatment showed the highest reduction (2.37±0.61), followed by F7 (3.46±0.56) and F0 (4.83±0.41). This shows that the longer the fermentation, the higher the substrate consumption and the effectiveness of waste reduction by BSF larvae.

Abstract

Using synthetic pesticides has polluted the environment, so efforts are needed to find alternative natural pesticides from plants. This study examines plant species with potential as botanical pesticides in Bowi Subur Village, Masni District, Manokwari Regency. The research method used is descriptive, with a sampling technique combining plot line transects, and it was conducted along 13 transects corresponding to the housing areas in Bowi Subur Village. The plants were documented, and relevant literature was reviewed. The inventory results identified 46 plant species from 25 families with pesticidal properties. Of these, 35 species are used for pest control, seven for disease management, and one for weed control. Additionally, three plant species were found to be effective for both pest and disease control. Most parts used for pesticide purposes are leaves, accounting for 19 plant species. We conclude that most species of plants used as natural pesticides are cultivated plants. Therefore, wild plants with potential for botanical pesticides are essential for further study their properties.
