Abstract

The objective of this study was to assess the ratio of fruit fly captures using attractants derived from basil and celery extracts, as well as to examine the impact of attractant concentrations in basil and celery leaf extracts on fruit fly catches. Traps made from recycled mineral water bottles were baited with basil and celery extracts containing essential oils known for their attractiveness to fruit flies. The findings indicated that traps using basil extract captured a greater number of fruit flies compared to those with celery extract. Furthermore, varying concentrations of the attractants significantly influenced fruit fly captures. The highest yield of fruit fly captures was observed at a 20% concentration of basil extract. The 20% concentration of basil extract had a higher number of fruit fly captures compared to the 10% and 30% basil extract concentrations, as well as the 10%, 20%, and 30% celery extract concentrations. The study results demonstrated a significant difference in the number of fruit fly captures between basil and celery extracts, with the highest number of captures observed with a 20% concentration of basil extract.

Abstract

Octopus fishing activities are increasingly being carried out by local fishermen making the variety of catches uncontrollable. It is feared that this diversity of catches will affect the biological condition of the octopus, which will lead to a decrease in the catch of fishermen. This study aims to: (1) determine growth patterns, body shape, age group, condition factors, spawning/maturity fit and catchability in octopus fisheries management, (2) biological dimensions of octopus fisheries management, and (3) identify attributes / lever indicators to increase the index value and sustainability status of the biological dimensions of octopus fisheries management. The results showed that the growth patterns of octopuses landed on Pandanan Beach, North Lombok Regency, were negative allometric with a b value of 2.1600. Meanwhile, octopus body shape is in the less flattened category with a condition factor (K) value of 1.85, with 2 age groups, namely the first age group with a length range of 24 cm - 48 cm and the second age group with a length range of 49 cm - 68 cm. Meanwhile, the number of octopuses worth catching was 238 which weighed > 320 grams, and 2 octopuses that were not yet fit to catch weighed < 320 grams. The sustainability status of octopus management from the biological dimension obtained a value of 52.34% with a fairly sustainable status. The attributes that need priority attention are stock enrichment and range collapse. Changes to these two attributes will affect the increase or decrease in the value of the biological dimension sustainability index.

Abstract

Minor and toxic elements in edible mushrooms are cultivated in residential areas of Mataram, West Nusa Tenggara. Minor elements are zinc (Zn), copper (Cu) and toxic elements such as lead (Pb), cadmium (Cd). Metals will be dangerous if they enter the body's metabolism in amounts that exceed the specified threshold.The purpose of this study was to determine the levels of minor elements and toxic elements in consumption mushrooms. This research was conducted to analyze minor and toxic metals using Atomic Absorption Spectrophotometer (AAS). The samples used in this study were mushrooms that are usually consumed by the public, namely, Pleurotus osteratus and Auricularia auricula-judae. The research method used is descriptive quantitative, namely to determine the levels of minor metal elements and toxic metal levels of consumption mushrooms. The results showed the highest minor levels of Zn in Pleurotus osteratus were 131.34 mg/kg and Auricularia auricula-judae mushrooms were 74.5 mg/kg. Toxic levels of Cd in Pleurotus osteratus are 0.547 mg/kg. While the levels of Cu and Pb in the analysis results are still within the maximum limit. The levels of Zn and Cd in each sample exceeded the maximum limit according to the Decree of the Directorate General of POM No. 03725/B/SK/VII/89 and the Indonesian National Standard SNI 7387:2009.

Abstract

Seaweed (E. cottonii) is a type of seaweed from the Rhodophyta class which has anti-diabetic activity so that it can control diabetes mellitus. The purpose of this study was to determine the effect of E. cottonii extract on body weight and blood sugar levels in mice (Mus musculus) type 1 diabetes mellitus. This study used a completely randomized factorial design with five treatments and three replications. 20 mice were divided into 5 groups: normal mice (KN), negative control (K-), positive control (K+), E. cottonii extract dose of 0.4 ml/g BW (P1) and E. cottonii extract dose of 0 .7 ml/gBB (P2). The extraction of E. cottonii used the maceration method with 96% ethanol solvent. All groups of mice were induced with 0.3 ml of STZ for 3 consecutive days. After an increase in blood glucose levels, the mice in the K(+) group were given metformin at a dose of 0.4 ml, P1 was given E. cottonii ethanol extract at a dose of 0.4 ml/g BW and P2 at a dose of 0.7 ml/g BW. Extract administration was carried out for 7 days. The results showed that E. cottonii extract had an effect on increasing body weight and decreasing blood sugar levels in type 1 diabetes mellitus mice. The increase in body weight and decrease in blood sugar levels was in line with the high doses given.

Abstract

Sesaot River is a river located in Narmada, West Lombok. The Sesaot River has been widely used by the surrounding community for their agricultural, plantation and daily activities. The high activity of the people around the river causes a decrease in the quality of river water. Macrozoobenthos is a bioindicator that can be used to describe a water's air quality. The purpose of this research is to examine the water quality of the Sesaot River utilizing macrozoobenthos as a bioindicator. The study was carried out at three different locations along the Sesaot River: upstream, middle, and downstream. At each observation site, macrozoobenthos ecological study and measurements of river water physical and chemical parameters were performed. According to observations, the pH, DO, and TDS of river water remain within the range of acceptable environmental quality standards. The macrozoobenthos found in the Sesaot Narmada river consist of 3 classes, 8 families and 8 species. Gastropoda, Mollusca, and Insecta are the third class discovered. The macrozoobenthic diversity index values discovered ranged from 0.8 to 1.35. Based on these findings, the macrozoobenthos diversity at the three locations is low. The uniformity index values obtained at the three stations ranged from 0.03 to 0.07, indicating that the distribution of individuals was unequal and unbalanced. At the three stations, the dominance index ranged from 0.27 to 0.55. Based on the findings, it is possible to conclude that the water quality of the Sesaot Narmada river is moderately to badly polluted.

Abstract

Nutmeg leaf, lemongrass, and bee nests contain bioactive compounds that have potential as mosquito repellents. The purpose of this study was to learn about the bioactivity of a combination extract of nutmeg leaf, lemongrass, and bee nests, as well as to determine the efficient mosquito repellent lotion recipe from a combination of nutmeg leaf, lemongrass, and bee nests extract. The maceration process was used for extraction. Total flavonoid content was estimated by comparing it to the flavonoid quercetin. The absorbance value was measured with a UV-Vis spectrophotometer. The concentration of the extract combination in the lotion used was 0%, 2.5%, 5% and 10%. The total flavonoid concentration was found to be 16.67 mgQE/g. The 2.5% formula lotion has a protective power of 22%, the 5% formula lotion has a power of 62.96%, and the 10% formula lotion has a power of 82.41%. From these results, it can be seen that a formula with a concentration of nutmeg leaf, lemongrass, and bee nests as much as 10% can be the most effective mosquito repellent. The outcomes of this study are expected to help the community select environmentally friendly and safe insect repellents.
