Abstract

Entomopathogen is one of the biological agents that infects the insects and can damage the body's metabolic system of insects. This objective of the study were to determine the entomopathogenic activity of S. marcescens on mortality of coconut leaf beetles larvae (B. longissima), and the time needed to reach LT50. The study used an experimental method with 6 treatments of varying S.marcescens volumes, consisting of A (distilled water as a control), B (5 ml), C (7.5 ml), D (10 ml), E (12.5 ml), and F (15 ml) with 4 replications. The data were analyzed using ANOVA and Probit LT50 test. The results showed that the volume of S.marcescens had an effect on mortality of coconut leaf beetle B. longissimi larvae. The best mortality rate at treatment E is 78% with the value of LT50 in treatment F is 42.15 hours. S.marcescens has entomopathogenic activity in coconut leaf beetles (B. longissima) Gestro larvae.

Abstract

Indonesian local fruit is a type of local fruit that grows naturally and originated from the Indonesian region. The research aimed at determined the diversity of Indonesian local fruits that can be consumed by humans so that they can be the basis for management and policy making related to the creating of route-tracking and thematic gardens of local fruit in Purwodadi Botanical Gardens. The data was collected using direct observation method, while the utilization and potential species data are based on interviews and literature studies. The result showed, there are 96 species of local fruit that are included in 24 families.

Abstract

The research was aimed at explaining the morphometric ratio of fiddler crab (Uca sp.) based on the difference among the population in Tanjung Panjang Nature Preserve. The technique of data collection was exploration with quantitative descriptive approach. The data analysis test applied average test and T- test. Findings revealed that the variation of the characteristics of morphometric of the two population was different on the characteristics of major claws propondus (2,55±0,16 mm) with the highest variation was found in station II (0,75±0,09 mm). The morphometric characteristic variations which were significantly different between the two population were carapace, major claws, and mouth. The variations among the population were clearly, seen through carapace posterior width, major claws propondus, major claws dactylus major claws and mouth length.

Abstract

Research aimed to find out morphological characteristics and proximate analysis of Momala Gorontalo corn (Zea mays, L.) variety. The research applied observation method by doing observation towards Momala Gorontalo corn variety. The data analysis used quantitative descriptive analysis. The morphology characteristics of Momala Gorontalo corn were average plant height was 146.47 cm; average cob height was 73.88 cm; average stem perimeter was 8.46 cm; average leaves number was 12; average leaves strand was 86.59 cm; average leaves midrib was 16.25 cm; average leaves strand width was 8.71 cm; average leaves strand direction was a bit curving; average axilla corner was 39,950; average leaves tip shape was sharp; at grain was 5,86%; at corn hair was 83,76%. Average cob length was 12,58 cm; average cob diameter was 3,34 cm; average cob weight with corn husk was 88,58 g, average cob weight without corn husk was 60,74 g, average seeds number per line was 20, and weight of 1000 grains was 272 g. The proximate analysis of Momala Gorontalo corn for moisture content was 14,82 ± 0,04%; ash content was 1,35 ± 0,01%; crude protein content was 11,51 ± 0,24%; crude fat content was 4,62 ± 0,48%; carbohydrate content was 67,68 ± 0,67%; value of Nitrogen Free Extract (BETN) was 58,36 ± 0,93% and value of metabolic energy was 2886,25 ± 14,68 Kkal/100 g
