Coral reef ecosystems have several important roles in support life of various aquatic organisms, Damage to the coral reef ecosystem directly and indirectly, sooner or later will threaten the sustainability of the use of these resources (social economy) and the safety of the community. Observations were conducted in KEK Mandalika coastal at 6 observation points less than 10 m. The results showed that the highest percentage of live coral cover was found in Kuta Mandalika coastal at PIT 4 area (30%, damaged category, moderate status). While the lowest percentage of coverage was at PIT 5, which was 2% (damaged category, bad status). Overall the percentage of coral cover in the Kuta Mandalika area is included in the damaged category. One of the reasons is because at the lowest tide on the beach, the volume of water is very small so that many hard corals are exposed to solar radiation. This limits the types of hard corals that can grow in the intertidal zone of Mandalika coastal. Genus diversity at this location is low, ranging from 0.0782 to 0.1288. Several genera of the Nephtheidae family dominate the observation sites and form colonies of the same genus with a fairly large distribution. The average value of environmental parameter measurements in the Mandalika coastal is included in the good category for soft coral habitat and growth.

Identification of soil insects in a certain type of habitat requires practical, easy, inexpensive, and efficient collection methods so as to obtain high abundance and diversity of soil insects. This study aims to analyze the diversity and abundance of soil insects using several trapping methods in Jeruk Manis Protected Forest in East Lombok. There are five trapping methods applied in this study; (i) pitfall trap, (ii) pitfall traps with bait, (iii) yellow pan traps, (iv) soil sampling, and (v) forest floor collection. The findings show that the overall diversity of soil insects in Jeruk Manis Protected Forest is moderate (1.44), while its evenness level is low (0.48). Soil sampling method provides diversity value of 2.36 and evenness level of 0.89, which is also the highest one among the other methods. Pitfall traps with bait give high individual number of soil insects (10.577 individuals). The highest number of soil insect orders is obtained through forest floor collection with 11 orders, while the highest number of soil insect families is obtained through pitfall trap with 30 families. The taxa of soil insects with relatively highest abundance consecutively are Hymenoptera (Formicidae), Collembola (Isotomidae, Entomobryidae), Coleoptera (Hydrophilidae, Ptiliidae, Scarabeidae), and Diptera (Drosophilidae).

Identification of soil insects in a certain type of habitat requires practical, easy, inexpensive, and efficient collection methods so as to obtain high abundance and diversity of soil insects. This study aims to analyze the diversity and abundance of soil insects using several trapping methods in Jeruk Manis Protected Forest in East Lombok. There are five trapping methods applied in this study; (i) pitfall trap, (ii) pitfall traps with bait, (iii) yellow pan traps, (iv) soil sampling, and (v) forest floor collection. The findings show that the overall diversity of soil insects in Jeruk Manis Protected Forest is moderate (1.44), while its evenness level is low (0.48). Soil sampling method provides diversity value of 2.36 and evenness level of 0.89, which is also the highest one among the other methods. Pitfall traps with bait give high individual number of soil insects (10.577 individuals). The highest number of soil insect orders is obtained through forest floor collection with 11 orders, while the highest number of soil insect families is obtained through pitfall trap with 30 families. The taxa of soil insects with relatively highest abundance consecutively are Hymenoptera (Formicidae), Collembola (Isotomidae, Entomobryidae), Coleoptera (Hydrophilidae, Ptiliidae, Scarabeidae), and Diptera (Drosophilidae).

The dry powder of S. sesban leaves was extracted using water as the single solvent. Bioassay of S. sesban leaf extract was carried out on cabbage caterpillars (Plutella xylostella larvae) and Diadegma semiclausum imago on cabbage plants using a variation of storage time design. Mortality data of P. xylostella larvae and D. semiclausum imago were respectively processed by probit analysis to determine LC50. The results showed that the insect repellent content of S. sesban leaves was a compound from the saponin group and was unstable during simplicia storage, extract storage and also unstable in water before and during application. Storage of S. sesban leaf simplicia from 1 to 3 months only slightly reduced the lethal toxicity of the extract to P. xylostella larvae (mortality from 95 to 80% or LC50 from 28.82 to 28.8...

They are associated with mangrove as life, shelter, spawning, and also as a place to get food to support the growth them. The purpose of this reaserch was to look at the effect of mangrove species and substrate type on the distribution Mollusks (Gastropods and Bivalves) in the mangrove ecosystem of Pelangan Village, district of Sekotong, west Lombok regency. This type of reaserch is descriptive explorative. Sampling was done by purposive sampling method with determine tree species, size, and substrate. Repeatation held six times each mangrove species. The results showed that there are 25 speciesd of mollusk in mangrove ecosystem, the most abundant species of gastropod in mangrove species is Clypeomorus moniliferus with a value of 6.9 ind / m2 contained in Osbornia octodonta. As for the distribution of each species of gastropods and bivalves are not affected by the mangrove s...

Cabbage pest control by eradicating Plutella xylostella larvae is considered less effective because the cabbage plant has been damaged due to infection with P. xylostella eggs and larvae. Thus, the control target needs to be shifted to prevent P. xylostella amago from laying eggs (ova-positioning) on cabbage plants. This study aims to determine the anti-ovipositor power of Sesbania sesban leaf extract against P. xylostella. The leaves of S. sesban were air-dried and then ground. The dry powder (simplicia) of S. sesban leaves was extracted with water as the sole solvent. The water-extract of S. sesban leaves was tested for anti-ovipositor against P. xylostella in situ on cabbage plants according to a completely randomized block design. Experimental groups were made according to variations in extract concentration. Complete randomization was carried out on experimental units in each group according to the var...
