Anthracnose disease is a crucial problem in the cultivation of papaya. It is caused by C.gloesporioides. one way to overcome this problem was by using natural fungicides. Some of the natural substances that have natural fungicides as their property are noni, basil, and guava. The research was conducted at the Microbiology laboratory of the Faculty of Agriculture, Fisheries, and Biology of Universitas Bangka Belitung January to April 2016. The research utilizes Randomized Analysis Complete Design with Factorial structure. The first factor are the extracts (E), consists of noni leaves (E1), basil leaves (E2), and guava leaves (E3). The second factor are the concentrations of the extract, consists of 0% (K0), 10% (k1), 20% (K2), 30% (K3), 40% (K4), 50%(K5), and 60% (K6). The data was analysed using analysis of variance at Î± 5%, with the used of SAS Program (Statistical Analytic System), if the effect was found significant, the data was further analysed using DMRT (Duncan Multiple Range Test). The research result showed that the extract of guava leaves at 30% concentration provided the best result in inhibiting the growth of C.gloesporioides in papaya.

One of the problems an industrial pepper in Indonesia is the lower quality of production by the farmers. To overcome these problems we must have to do research to get a good technique in pepper processing and the good quality of pepper in accordance Indonesian National Standard. This research using a factorial randomized block design with three replications of two treatment factors. The first factor is physiologic mature (M) and the second factor is the soaking method (P). The research phase includes the preparation of tools and materials. Soaking pepper, cleaning the skin and stems, drying and analysis of pepper quality test. Changes observed in this research is the content of water, the level of colored pepper, and the levels of mold contamination. The result of this research shown the mature physiologically significant effect on the levels of pepper blackish in color and content of seeds lightly. Pepper levels blackish color shown on the highest passing phase that is optimum ripe 0.12% and the lower passing phase optimum ripe is 0.01%. The highest levels of seed lightly on shown at the mature phase towards optimum ripe 1.66% and the lower it show through the mature phase that is 0.71%. White pepper research results both in treatment and in the treatment of physiologically mature immersion method meet the Indonesian National Standard.

Pests are one the reason of declined in crop production. one of them is Spodoptera litura. The purpose of this research was to determined the mortality rate of Spodoptera litura caused by M. anisopliae infection. The research is conducted at the Microbiology Laboratory of Agricultural Technology Department of the Faculty of Agriculture, Fishery, and Biology of Universitas Bangka Belitung. The research used factorial randomized block design with 2 treatment factors. The first factor ( stage larvae) consists of L1=instar 3, L2=instar 4. The second factor (the concentration) consists of V0=control, V1= 30 g/l of water, V2=35 g/l of water, V3= 40 g/l of water, V4= 45 g/l of water. The data is analyzed using ANOVA with confidence level of 95% and is further tested using the Tukey Test with the confidence level of 95%. The research results show that a concentration of 30 g/l of water and 35 g/l of water the mortality rate reaches 88,89%, while at the concentration of 40 g/l of water and 45 g/l of water the mortality rate reaches 100% with 3 to 7 days span of mortality. The larvae infected with M. anisopliae experience behavioral changes such as decreased appetite, less active movement, inactive, and transformed color to black with mycelium covering a part of the body.

Rice crops are the main source of staple food for the Indonesian people, as well as in the Bangka Belitung province. The cultivation of rice crops is still through various obstacles, such as the attack of Leptocorisa oratorius Fabricius, which attacks the rice plants after flowering by sucking the grain. The aim of this study was to know the effect of L.oratorius population on the rice yield, to know the number of L. oratorius that can decrease the 15% paddy yield and to know the percentage of rice loss based on the number of L. oratorius population in the Kimak village, Merawang district, Bangka regency. The research was conducted on November 2017 to January 2018 on paddy field in Kimak village. This research used experimental method with Completely Randomized Design (CRD) wich consist of 8 treatments and 2 replications. The treatment was the differences L.oratorius population. Consist of: without L.oratorius, 2 L.oratorius, 3 L.oratorius, 4 L.oratorius, 5 L.oratorius, 6 L.oratorius, 7 L.oratorius and 8 L.oratorius. The result showed that the number of L. oratorius has significant effect on rice yield, 3 population of L. oratorius per 50 cm x 50 cm able to reduce the rice yield by 15% and the percentage of yield loss at the treatment of 2 - 8 L.oratorius is about 10.97% up to 28.98%.

Plant Growth and production of melon is affected by fertilizer so that alternative application of technology can be used liquid organic fertilizer (LOF) from pineapple peel. The purpose of this research is to know the effect ofliquid organic fertilizer on growth and production of melon plants in ultisol soil. Experimental methods used with single factor Randomized Block Design with 7 treatment levels were: inorganic fertilizer, 20 mL / 1 liter of water, 35 mL / 1 liter of water, 50 mL / 1 liter of water, P4 65 mL / 1 liter of water , P5 80 mL / 1 liter of water and 95 mL / 1 liter of water. The results of this study indicate the use of liquid organic fertilizer (LOF) does not gave a real effect on the growth and production of melon plants. Growth of melon plants treated 20 mL / 1 liter of water tend to be better while for production tend to be better at treatment 35 mL / 1 liter water.

Pepper submersion period with addition karamunting leaf (Melastoma malabathricum) is one expected postharvest to increasing white pepper quality. This research aims to know the influence of submersion period and karamunting leaf dose and also it is interaction to white pepper quality. This research was conducted at Balunijuk village, Bangka Regency and quality testing in UPTD Hall, Certification And Quality Control, Departement of Industry and Commerce Bangka Belitung Island. This research used Randomized Completely Design with 2 factors and F-test. The first factor (P) submersion period: (P0) as control 14 days, (P1) 9 days, (P2) 7 days and (P3) 5 days and two factor add karamunting leaf doses (K): (K0) as control without add karamunting leaf dose 0 g, (K1) 1 00 g, (K2) 150 g, and (K3) 200 g. Each unit of and using 2 kg of fruit pepper. Further testing used Duncan Multiple Range Test with 95% level of confidence. The result showed submersion periods have the significant effect for foreign object, white pepper level, and atsiri oil content. 5 days submersion had the best yield on atsiri oil content (2.44%). There is no interaction between submersion periods by adding karamunting leaf to the quality of white pepper.
