Abstract

Phytotelmata are plants that hold water in one or more parts of their body of plant. The water that is collected in the body parts of the phytotelmata is used as a breeding habitat for Aedes spp. This study aimed to determine the diversity of phytotelamata species in Kediri, which is one of the cities with the highest DHF cases in January 2019 in East Java. This research was descriptive observational. The sampling point was determined using purposive sampling method. The results showed that there were nine species of phytotelmata which were used as breeding sites for Aedes spp. in Kediri, namely Musa paradisiaca, Colocasia esculanta, Neoregelia spectabilis, Bambusa sp., Neoregelia charm, Aechmea fasciata, Xanthosoma sagittifolium, dan Bromelia sp. Species of Aedes founded were mostly Ae. albopictus. The average volume of water contained in one part of the phytotelmata is 90.11 ml with a water temperature ranging from 25-26oC and pH of water is 6-7.

Abstract

The Lecanicillium lecanii is an entomopathogenic biological agent that can be used to control plant pest organisms. This study aimed to determine the use of liquid media derived from boiled potato water as a propagation material for the Lecanicillium lecani. The propagation of the fungus starts from propagation on PDA (Potato Dextrose Agar) sloping agar media, propagation or inoculation of the fungus on solid media (rice), then propagation of the fungus on liquid media (potato boiled water). The results of this activity showed that liquid media (potato boiled water) can be used as a medium for propagation of the Lecanicillium lecanii because potatoes have a starch content with good nutrients and carbohydrates to be used as growth media for entomopathogenic for example is Lecanicillium lecanii.

Abstract

This study aimed to determining how the production process of Azotobacter sp. using liquid media as the biological agent of Azotobacter sp. Azotobacter sp. is a nitrogen fixing bacteria as fertilizer of soil. Azotobacter sp. including natural biological agents that are environmentally. The process production of the biological agent was used liquid media from soybean which carried out in the coordinator office of PTPH bojonegoro. The result showed that propagation of Azotobacter sp. can be done with the stages of making bacterial isolation on Natrium Agar (NA) and making liquid media with soybean (based ingredients). The calculation method using the TPC method is done by counting the number of bacterial colonies that appear on the petridish. From the results of the calculation of the TPC the average number is 3,8 x 108, showed that is feasible to be used as an effective growth regulator fertilizer.

Abstract

The used of refugia plants can be a solution in pest control by providing microhabitats for natural enemies. There are predators and parasitoids as alternative hosts. This study aimed to determine the diversity of insect pests in rice plantations using refugia and without refugia plants in Besur Village, Lamongan. This study used the rice variety Mentik Wangi Susu. The sampling method used 3 kinds of traps: sweep net, pit fall trap, and yellow sticky trap. The results showed that the insect pests found were 5 orders, 11 families, and 14 species with a total of 1272 individuals on refugia land and 1534 individuals on land without refugia. The Shanon-Weiner diversity index (H?) of insect pests on refugia land is H? = 1.93 and on land without refugia H? = 1.86 which is in the medium criteria.

Abstract

Abstract Dengue hemorrhagic fever (DHF) is a disease that is a problem in society. Lamongan Regency has been declared a DHF KLB (Extraordinary Event) with a number of 86 cases in 2015. The village with the highest incidence of DHF in Lamongan Regency is Payaman Village. This study aims to analyze the physical and chemical factors of the water used as a breeding ground for Aedes spp. This research is a descriptive study with a cross sectional approach. Sampling was carried out in 50 houses located in Payaman Village, Solokuro, Lamongan district. The research parameters there are volume of water, temperature, pH, value of water turbidity (NTU), and DO value. The results showed that each type of container has different physical and chemical properties of water. The highest volume of water is in the bathtub type with an average water volume of 152,500 ml. While the least was in the axillary types of Musa paradisiaca (185 ml) and Colocasia esculenta (177 ml). The average water temperature at the breeding site ranges from 25-30oC. The acidity of the water ranges from 6-7. The value of DO levels ranged from 5-8.5 ppm. The value of water turbidity ranges from 4.50-25 NTU with an average of 15.31 NTU.

Abstract

Spodoptera litura F. is a plant pest organism (OPT) on shallot plants that must be prevented so that shallots become productive. One way to prevent it is good and not to damage the environment is the use of tumangsari plants in the form of celery plants. The purpose of the study was to determine the effectiveness of celery (Apium Graveolens L.) as a pest population of Spodoptera Litura F. Repellent Plants in the Cultivation of Shallots (Allium Ascalonicum L.) in Pesanggrahan Village. This research is an experimental study using a randomized block design (RAK) pattern, one way ANOVA test data analysis technique with 5% significance and post hoc follow-up test with the smallest difference analysis. The results showed that celery plants were effective in suppressing Spodoptera litura F. pest attacks. The most effective treatment was 4 PTS treatment which could reduce Spodoptera litura F. population and zinc intensity of Spodoptera litura F., which were 1.66 and 0, respectively. 15%.
