Abstract

Soil arthropods play an important role in nutrient cycling and maintenance of soil structure. Thus, their abundance and diver­sity can indicate the biological quality of the soil. Due to different soil management practices, arthropods are also very sensitive to en­vironmental changes. This study aims to analyze the abundance and diversity of soil arthropods and the environmental factors that sup­port the abundance of soil arthropods in terrestrial of Situ Lengkong Panjalu, West Java, Indonesia. The methods used to obtain samples of soil arthropods are pitfall trap. Soil arthropod data were analyzed to determine the Shannon diversity index (H'), Margalef richness index (R), and Evenness index (E). The effect of abiotic environmental fac­tors was analyzed using Principal Component Analysis (PCA). A total of 1263 arthropods were found in Situ Lengkong Panjalu, belonging to 11 orders, 24 families, and 32 morphospecies. The current work determined the scores of H'= 2.08, R = 3,08, and E = 0.72 of soil arthropods in Situ Lengkong Panjalu, West Java, Indonesia. Results revealed that humidity is one such environmental parameter affecting the presence of soil arthropods in Situ Lengkong Panjalu, West Java, Indonesia. This research can be used as a guide in validating and conservation of the habitat of soil arthropod species on West Java

Abstract

Ruku-ruku (Ocimum tenuiflorum L.) is widely recognized as a medicinal plant used in traditional medicine. The leaves are the most commonly utilized part of the plant, particularly for treating various health conditions such as fever, cough, joint and nerve pain, oral ulcers, tinea versicolor, nausea, and vomiting. Ruku-ruku leaves contain various essential nutrients, including calcium, iron, zinc, vitamin A, and vitamin C. This study aimed to determine the vitamin C content of ruku-ruku leaves. The research employed a quantitative descriptive method using the iodimetric titration technique. The samples consisted of young, mature, and old leaves collected from Tulo Village, Sigi Regency, Indonesia. Vitamin C content was measured with three replications for each sample. The results showed that the highest vitamin C content was found in young leaves, with an average value of 70.89 mg/100 g, followed by mature leaves at 54.18 mg/100 g and old leaves at 33.80 mg/100 g. Differences in vitamin C content were influenced by the level of leaf maturity, with younger leaves containing higher concentrations of vitamin C than older leaves.

Abstract

Bivalves are one of the molluscan groups that play an important role in maintaining the ecological balance of mangrove ecosystems. Their presence and abundance are influenced by environmental conditions, making them useful indicators of habitat quality. This study aimed to determine the abundance of bivalves in the mangrove ecosystem of Pinotu Village, Toribulu District, Parigi Moutong Regency, Central Sulawesi, Indonesia. A quantitative descriptive approach was employed in this study. The research sites were selected using a purposive sampling technique based on the presence of suitable bivalve habitats. Sampling was conducted using the belt transect method at two observation stations, each covering an area of 500 m². Field sampling was carried out during low tide on 17–18 December 2025. Collected bivalve specimens were identified using taxonomic identification keys. In addition, environmental parameters, including water temperature, salinity, and pH, were measured. The collected data were analyzed using the species abundance index (R) and the Relative Abundance Index (RAI). The results revealed the presence of four bivalve species belonging to two orders and two families, namely Polymesoda erosa (39 individuals), Polymesoda expansa (19 individuals), Polymesoda bengalensis (38 individuals), and Anadara granosa (9 individuals), with a total of 105 individuals recorded. The species abundance index (R) value of 0.64 indicated a low level of bivalve abundance. The highest Relative Abundance Index values were observed for Polymesoda erosa (37.14%) and Polymesoda bengalensis (36.19%), both classified as highly abundant. In contrast, Anadara granosa exhibited the lowest relative abundance value (8.57%) and was categorized as having low abundance.

Abstract

Organic fertilizer is a type of fertilizer produced from natural materials derived from living organisms. One form of organic fertilizer is liquid organic fertilizer, which has the advantage of providing nutrients that are more readily available and easily absorbed by plants. This study aimed to analyze the effect of different concentrations of liquid organic fertilizer derived from mustard green vegetable waste on the growth of cayenne pepper plants (Capsicum frutescens L.). The study employed a Completely Randomized Design (CRD) consisting of five treatment levels: P0 (control), P1 5% (10 mL), P2 10% (20 mL), P3 15% (30 mL), and P4 20% (40 mL). Each treatment was replicated three times, resulting in a total of 15 experimental units. The observed parameters included plant height, stem diameter, and number of leaves. Data were analyzed statistically using Analysis of Variance (ANOVA), followed by the Least Significant Difference (LSD) test when significant differences were detected. The results showed that the application of liquid organic fertilizer derived from mustard green vegetable waste had a significant effect on plant height, stem diameter, and leaf number of cayenne pepper plants. Treatment P2 with a concentration of 10% (20 mL) produced the best results across all observed parameters. This finding indicates that this concentration was able to provide sufficient and balanced nutrients to support vegetative plant growth, whereas increasing the concentration to 15% and 20% did not result in a significant improvement in growth. Therefore, liquid organic fertilizer derived from mustard green vegetable waste has the potential to be utilized as an alternative organic fertilizer for enhancing the growth of cayenne pepper plants, with an optimum concentration of 10% (20 mL).

Abstract

This study aimed to analyze the protein content of Anguilla marmorata collected from Lake Talaga, Dampelas District, Donggala Regency, and to explore its potential for development as a learning medium. A descriptive quantitative approach was employed. Protein content was determined using the Biuret method coupled with UV–Vis spectrophotometry, with Bovine Serum Albumin (BSA) used as the standard. The protein contents obtained from three replicate measurements were 19.61%, 19.37%, and 20.43%, respectively, with a mean value of 19.80% and a range of 19.37–20.43%. These results indicate that the analyzed A. marmorata sample had a relatively high protein content, with consistent values across replicate measurements. The feasibility assessment of the developed flipbook yielded an overall mean score of 87.85%, corresponding to the “highly feasible” category. The content expert, media expert, and design expert assessments were 92.5%, 78.5%, and 88.0%, respectively, while the student response score was 92.4%. Overall, this study provides preliminary information on the protein content of A. marmorata from Lake Talaga and demonstrates the potential of the research findings to be integrated into a flipbook as a contextual learning resource for biology and nutrition-related topics.
