Abstract

The AB-Mix is one of the sources of nutrients that can be used to meet the requirements of the hydroponic system, but at the moment, the problem is that using it requires a considerable cost. So, we need to look for cheap and abundantly available alternatives in the neighborhood. The study investigated the effects of eco-enzymes and AB-Mix on the growth of Brazilian spinach (Alternanthera sissoo Hort) using fruit skins in the wick hydroponic system in Sendang Agung district, Lampung Tengah. This study uses a completely randomized design with two factors. AB-Mix is the first factor, and eco-enzymes are the second factor, each repeated three times. Growth parameters observed and dry weight calculated. ANOVA's Two-Way Test and DMRT's 5% Advanced Test are used to analyze the data. The results showed that treatment with AB-Mix 5 ml and eco-enzyme 10 ml gave the best results for the plant.

Abstract

Rolling tongue (the ability to fold the tongue into a certain shape like a roll) is often used as a topic in genetic research because it is considered an example of simple genetic inheritance. This phenomenon involves a person's ability to roll the tongue up laterally which is often assumed to be a trait determined by a single dominant gene. However, further studies have shown that Rolling tongue is likely influenced by complex genetic and environmental factors. This study aims to determine the population of students at the State Islamic University of Sultan Thaha Saifuddin Jambi who can perform the Rolling tongue movement and also examine the factors that influence a person to be able to perform the Rolling tongue movement . This study uses a quantitative method with an observational approach to observe variations in the Rolling tongue phenotype in UIN STS Jambi students. From this study, it was found that the number of respondents was 104 students who were tested for Rolling tongue ability, who could perform the Rolling tongue movement were more than students who could not perform the movement. By analyzing data from various populations, this study concluded that Rolling tongue is not entirely inherited in a simple dominant manner but involves interactions between genetics and the environment

Abstract

This high level of organic waste poses significant environmental risks if left unmanaged. Therefore, there is a need for waste management strategies that are simple, cost-effective, and environmentally sustainable. One such approach is vermiculture the cultivation of earthworms to convert organic waste into nutrient-rich vermicompost. Integrating Effective Microorganisms (EM4) and tomato waste into cattle manure feed has the potential to enhance nutrient bioavailability through microbial fermentation, which in turn supports earthworm metabolism and growth. This study aims to evaluate the productivity of Lumbricus rubellus and the efficiency of vermicompost production under different feed formulations. The experiment was conducted using a completely randomized design (CRD) with four feed treatments: cow manure (P1), cow manure + EM4 (P2), cow manure + tomato waste (P3), and cow manure + tomato waste + EM4 (P4), with three replications per treatment. The observed parameters included earthworm weight, earthworm length, vermicompost production, and proximate analysis of earthworm biomass. This study also assesses the impact of these feed combinations on the growth performance of L. rubellus and the resulting vermicompost yield, within the agroclimatic conditions of Pangalengan. Additionally, the nutritional composition of the harvested earthworm biomass is evaluated to explore its potential as a supplementary protein source for livestock feed contributing to sustainable and circular agricultural practices in dairy farming systems.

Abstract

Pollinator insects are insects that help the pollination process in plants by transferring pollen to other plants. The pollen attaches to the hairs and legs of the insect at the time when the pollinator's insect is foraging. This study aimed to analyze the diversity index and dominance index of pollinator insects in the Kebun Raya Institut Teknologi Sumatera. This research was conducted at the Kebun Raya Institut Teknologi Sumatera, specifically the orchard (guava and dragon fruit) and aesthetic garden. This study used purposive sampling by taking data directly at the observation site. Data analysis was used to calculate the diversity of pollinator insects within the ecosystem. The analysis involved calculating the diversity index (H') and dominance index (D). The study shows that pollinator insects come from 5 orders: Coleoptera, Diptera, Hemiptera, Hymenoptera, and Lepidoptera. Each observation location in the Kebun Raya Institut Teknologi Sumatera has a moderate category diversity index: guava orchards 1.93, dragon fruit orchards 1.53, and aesthetic gardens 1.60. The dominance index of each observation site showed values with low categories, namely guava orchards at 0.18, dragon fruit orchards at 0.32, and aesthetic gardens at 0.28. Visiting activities in the morning are dominated by the family Apidae, while daytime and afternoon are dominated by the family Nymphalidae. High temperatures lead to decreased activity of pollinator insects.

Abstract

Way Tahmi River is a crucial freshwater source for the local ecosystem and surrounding communities, providing essential ecosystem services such as habitats for diverse species, clean water, and support for agricultural and fisheries activities. However, anthropogenic pressures, including water pollution from domestic and industrial waste, land use changes, and overexploitation of natural resources, pose significant threats to the river's ecosystem. This study aims to assess the nekton diversity in Way Tahmi River as bioindicators of water quality. The research involved sampling nekton at three different stations, each chosen based on proximity to residential areas, dining establishments, and plantations. Physical and chemical parameters, including temperature, Ph dissolved oxygen (DO), salinity, and water clarity, were measured to evaluate environmental conditions. The results indicated that the identified nekton belonged to Actinopterygii and Malacostraca classes, with varying species composition across the stations. The Shannon-Wiener diversity index showed moderate nekton diversity, while evenness and dominance indices suggested a relatively balanced and stable ecosystem. These findings highlight the importance of nekton as bioindicators and the need for effective management strategies to preserve the aquatic ecosystem of Way Tahmi River.

Abstract

The use of organic fertilizers is considered to be beneficial by farmers such as increasing land productivity. Corn farming contributes the highest agricultural waste in Indonesia, such as stem litter, leaves and husks. This waste has the potential to be used as organic fertilizer because based on research it contains many nutrients in it. This study aims to evaluate the effectiveness of EM4-based microbial treatment in accelerating the composting of corn litter waste through observational qualitative analysis. The results of this study indicate that the addition of microorganisms can shorten the time to make organic fertilizer. On the 6th day, the corn litter waste sample that had been given EM4 had shown the appropriate criteria for organic fertilizer in the form of a neutral pH concentration of 6.5 and did not have a disturbing odor and a texture that was no longer stiff. These findings suggest that EM4 can be used to accelerate composting of corn waste into high-quality organic fertilizer, potentially supporting sustainable agriculture.

Abstract

Indonesia is recognized as one of the most biodiverse countries in the world, including in its diversity of stingless bee species. Diversity analysis is essential as a key consideration in optimizing outcomes in stingless bee cultivation practices. Morphometric analysis represents one of the methods used to assess stingless bee diversity; however, its application remains limited in Lampung Province. This study involved the collection of samples from seven different colonies across two regions in Central Lampung Regency. Morphometric measurements were conducted on eight specific parameters. The resulting morphometric data were then compared to published measurements of 20 reference species. Based on these comparisons, the morphometric characteristics of the stingless bee samples from Central Lampung indicate a close resemblance to species within the genera Heterotrigona, Tetragonula, and Geniotrigona.

Abstract

Acne vulgaris is an inflammatory skin disorder commonly caused by Staphylococcus epidermidis. Many anti-acne products on the market contain chemicals that have side effects for the user, so natural antibacterials are needed in the treatment of acne which have a smaller risk of side effects, namely by using fruit skins as ecoenzymes. This study aims to examine the effect of the concentration of ecoenzymes made from fruit peels on the inhibitory power of Staphylococcus epidermidis and knowing the optimal concentration of ecoenzymes in inhibiting the growth of Staphylococcus epidermidis bacteria. This research uses a quantitative approach with a Completely Randomized Design experimental research type. The antibacterial test used the well diffusion method with 3 different concentrations, namely 25%, 50% and 75%, the positive control used clindamycin and the negative control was sterile distilled water. The antibacterial test was conducted with three replicates for each concentration. ANOVA showed significant differences (p < 0.05). The results showed that the concentration of ecoenzymes had an effect on inhibiting the growth of Staphylococcus epidermidis. The most optimal concentration in inhibiting the growth of Staphylococcus epidermidis is ecoenzyme with a concentration of 75% with an average inhibitory zone diameter of 10.2 mm (strong category).
