Abstract

Soil insects play an important role as environmental indicator organisms, ecosystem balancers, and decomposers of organic matter. This study aims to determine the diversity of soil insects in the Lemor Botanical Garden, East Lombok. The diversity of flora and fauna in this area makes it suitable as a conservation site that also serves educational purposes. Sampling was conducted using pitfall traps, soil borers, and Berlese-Tullgren funnels at two stations: station 1 (ex situ) and station 2 (in situ). Data were analyzed using the Shannon-Wiener diversity index. The results showed that 44 species of soil insects were found, belonging to 11 orders and 23 families, with a total of 970 individuals. The most dominant species belonged to the family Formicidae, with 257 individuals. Overall, the soil insect diversity index on litter was H' = 1.778, on the soil surface H' = 2.265, and in the soil layer H' = 1.098. These results indicate that the diversity level of soil insects in the Lemor Botanical Garden is moderate and varies across habitat layers. This moderate diversity reflects a relatively stable ecosystem and supports the importance of Lemor Botanical Garden as a site for conservation and environmental education.

Abstract

Fruit flies (Bactrocera sp.) are important pests of horticultural crops because they can cause serious damage and reduce the selling value of the fruit. This study aims to determine the effect of lemongrass (Cymbopogon nardus) plant extract on the number of fruit fly catches and to determine the most effective concentration as a natural attractant. The study was conducted experimentally in a crystal guava plantation in Dasan Tapen Village, West Lombok, using a Randomized Block Design (RBD) with five treatments of lemongrass extract concentrations (0% - 60%) and three replications. Data were analyzed using one-way ANOVA and continued with the LSD test. The results showed that there were four species of fruit flies caught, namely Bactrocera dorsalis, B. carambolae, B. cucurbitae, and B. papayae, with a total of 671 individuals. The 60% concentration produced the highest number of catches (an average of 69), while the control without attractant did not produce any catches. Statistical analysis showed a significant effect between treatments (p < 0.05). It can be concluded that lemongrass ethanol extract has a significant effect on the number of fruit fly catches, and the highest concentration in this study (60%) is more effective than the concentration below it. The concentration of 60% has the highest capture compared to the concentration below it. The use of lemongrass as a natural attractant has the potential as an alternative to environmentally friendly pest control in an integrated agricultural system.

Abstract

Scylla serrata is one of the species included in the mangrove forest ecosystem which has high economic value for human life. Seeing that mud crabs have high economic potential both domestically and abroad with a fairly high level of demand and abundant availability of catches in nature, concerns arise about the condition of their population. This research aims to determine the population structure of mangrove crabs in the Bagek Kembar Mangrove Forest Area, West Lombok. The method used is purposive sampling. Sampling was carried out at 3 stations representing the entire research location area, namely on the seafront, in the middle and farthest from the arena facing the sea. Each station has its own characteristics. The distance between stations is 50 m. Each station is installed 6 folding trap with a distance between trap 10 m. The length, width, and high size are 50 cm, 30 cm, and 15 cm respectively. This tools are completed by 3 mm mesh size. The results of the research showed that the carapace length of male and female mud crabs that were mostly caught was in the 3 – 4.5 cm and 2.5 – 4.0 cm classes. The carapace width of male and female mud crabs most often caught is in the range of 4.4 – 6.5 cm and 3.5 – 5.5 cm. And the weight of the most commonly caught male and female mud crabs was in the class range of 11.39 – 111.5 grams and 13.77 – 74.5 grams. This research concludes that mangrove crabs that live in the Bagek Kembar Mangrove Forest Area, West Lombok, based on gender, carapace length, carapace width and body weight, are dominated by juveniles. Only a limited number reach catch size.
