Abstract

Toronipa Beach is known to have high biodiversity, especially in the Mollusca community such as Gastropoda and Bivalvia. However, research on the distribution and abundance of Mollusca species in this area, especially related to environmental changes, is still limited. To fill this gap, an analysis study was conducted on the structure of the Toronipa Beach Mollusca community as a basis for effective conservation efforts. Data were collected through purposive sampling methods at three different locations, then analyzed using the Shannon-Wiener Index method, evenness index, and dominance index. The results showed that the North of Toronipa Beach had the highest diversity with a Simpson index of 0.91, followed by the West with 0.76, and the East with 0.75. These differences in diversity reflect variations in microhabitats, such as substrates, water flow, and human activities, which affect the distribution and abundance of species. This study highlights the importance of proper management and conservation to maintain biodiversity in Toronipa Beach and provides a basis for further studies on the impacts of the environment and climate change on coastal ecosystems.

Abstract

Soybean-based food business and population growth drive the increase in soybean consumption every year in Indonesia. Soybean varieties and liquid organic fertilizer applications can help overcome losses in soybean plant growth and productivity. This study used a randomized block design (RAK) with treatment consisting of 2 factors with 3 repetitions. Factor i liquid organic fertilizer (p), consists of 4 levels, namely: p0 = 0 ml, p1 = 20 ml, p2 = 40 ml, p3 = 60 ml. the 2nd factor cultivar (k), consists of 2 types, namely: k1 = cultivar detam 1, k2 = cultivar detam 3. The results showed that the response and effectiveness of the application of soybean peel poc and different cultivars did not significantly affect the vegetative growth of black soybean plants, but when viewed as a whole p3 (60 ml) gave the highest value on the parameters of leaf area index 21 hst, root nodules, chlorophyll a, and chlorophyll b content.

Abstract

The intensive harvesting of Mangrove Crabs (Scylla serrata) has led to a significant decline in the population density of Scylla serrata in mangrove areas. Overfishing has resulted in a decrease in both the number and size of individual Mangrove Crabs and has altered the structure and composition of the population. This research aims to understand the morphometric characteristics of Scylla serrata, which will help sustain the population and protect mangrove areas as the native habitat for Scylla serrata and other organisms. Therefore, this study contributes to conservation and sustainable management efforts to ensure biodiversity. This type of research is descriptive-exploratory and aims to identify and analyze the size variations of Scylla serrata. The study was conducted at four points in the Essential Ecosystem Area (EEA) of Bagek Kembar Mangrove Forest, Sekotong, West Lombok, in both natural and rehabilitated zones. The results of this study found that the ratio of female to male Mangrove Crabs is 36:32, with females being more dominant in number. The morphometric characteristics of Mangrove Crabs in the Bagek Kembar Essential Ecosystem Area showed relatively uniform sizes across all sampling points, but some characteristics such as dactyl length, weight, and dactyl width showed significant differences, which may be influenced by the physiological condition of Scylla serrata and habitat conditions.

Abstract

Lettuce is a plant that is quite popular with the public. Not only does it have economic value but it also has quite high nutritional content. So one method used to maintain the stability of lettuce production on the market is by providing rice husk ash and monosodium glutamate (MSG). This research uses a non-factorial randomized block design (RAK) which consists of 5 levels, namely giving fertilizer without combination and giving combined fertilizer, namely P1 (Rice husk ash 100 grams/polybag), P2 (MSG 15 grams/polybag), P3 (Combination of rice husk ash and MSG with a dose ratio of 100 grams of rice husk ash : 15 grams of MSG), P4 (Combination of rice husk ash and MSG with a dose ratio of 75 grams of rice husk ash : 10 grams of MSG), P5 (Combination of rice husk ash and MSG with a dose ratio of 50 grams of rice husk ash: 5 grams of MSG). The study's findings demonstrated a significant impact on all parameters (plant height, number of leaves, leaf area index, and plant fresh weight) when a combination of rice husk ash and MSG was used. The results of testing the levels of chlorophyll a b and the total use of a combination of rice husk ash and MSG did not provide a significant effect. The most effective dose to increase the growth of lettuce plants was the use of a combination of rice husk ash and MSG with a level of P3 = 100 grams of rice husk ash: 15 grams of MSG.

Abstract

Childbirth is a process of expelling the results of fertilization through a flask from inside the uterus out of the uterus through the vagina spontaneously. Pain is an experience of feeling uncomfortable and unpleasant from a person's sensory and emotional side. The purpose of this study was to determine the effect of Mensage Effinage on reducing the intensity of labor pain in the first active phase. This study used a one-group pre-test post-test design experiment with a sample of 34 respondents. Data was collected using a Verbal Descriptor Scale (VDS) monitoring observation sheet. Data analysis using the normality test on the Wilcoxon Sign Ronk Anamis pararsenic test because the data is not normally distributed or has Wilcoxon status. The results of the study showed that the intensity of pain in the first stage of labor in the active phase can be reduced through effluent massage therapy. This is evidenced by the results of data analysis where p = 0.000 <0.05 so that the Ho result is rejected, H1 is accepted. Effluent Massage Therapy can be used as an alternative that needs to be applied to reduce pregnancy pain in mothers giving birth in the first phase of pregnancy. The conclusion is that massage effluent can reduce the intensity of pain in pregnant women in phase 1.

Abstract

Fusarium sp. is a serious problem for various plant commodities because of its ability to act as a pathogen and cause damage to plant anatomy and morphology. The rhizosphere fungus of the mother-in-law's tongue plant has more abundant inhibitory mechanisms and is able to directly inhibit hyphae growth and suppress the growth of pathogenic fungi, so it was chosen as a biocontrol agent in this research. The aim of this research was to determine the antagonistic properties and ability of the rhizosphere fungus from the mother-in-law's tongue plant (Sansevieria trifasciata Prain) against the fungus Fusarium sp. This research was carried out with data analysis starting with sterilization and making media, then taking soil samples from the rhizosphere of the mother-in-law's tongue using the purposive random sampling to continue with the isolation and purification stage of the rhizosphere fungus of the mother-in-law's tongue plant. Antagonist test of fungi from the rhizosphere of snake plant against the fungus Fusarium sp. carried out using a double culture method (dual culture). The data obtained were then analyzed using Microsoft Excel 2013 to obtain an average inhibition which shows the potential of fungi from the rhizosphere of the plants as controlling agents for the fungus Fusarium sp. The results of isolation and antagonistic tests, the five isolates of snake plant rhizosphere fungus (Sansevieria trifasciata Prain) have varying inhibitions ranging from very weak to moderate. The highest inhibition against Fusarium sp. was shown by isolate JDT12, while the lowest inhibition was shown by isolate JDT11. The antagonism mechanism found by isolate JDT12 is the antibiosis mechanism.
