Abstract

This research is intended to answer the obstacles in the cultivation techniques of shallots, especially in overcoming the low quality of growth, which in turn affects the yield and production of onions. In this experiment, spraying three types of frequency and four kinds of oligo-chitosan concentrations was tried throughout the growing onion period. Oligo-chitosan as a supplement, is given to the onion plants periodically, in various concentrations, in three different types of oligo-chitosan spraying, which they are (F1) given to plants aged 15 DAP and 45 DAP; (F2) given to plants aged 15 DAP, 30 DAP, and 45 DAP; and (F3) given to plants aged 15 DAP, 25 DAP, 35 DAP, 45 DAP. The oligo-chitosan concentration consists of four kinds of concentration, consisting of 0 ‰ (K0) as a control, 1 ‰ (K1), 2 ‰ (K2) and 3 ‰ (K3). The experiment was carried out in the field using a polybag, with a completely randomized environmental design with a 95% accuracy level. To determine the effect of treatment on the quality of growth of shallots, diversity analysis was carried out. From preliminary observations, it shows that the onion bulb growing power as a seed is quite good, while the treatment using oligochitosan gives significant results on increasing plant vigor, compared to not using oligochitosan. As for further observations that at plant height, the number of leaves and the number of tillers up to 50 days after planting, although it does not show any real effect of the treatment that was tried, but it can be suspected that the more frequency treatment given oligo-chitosan, more gives a better chance of yield than a few frequencies, while an oligo-chitosan concentration of 1 ‰ is sufficient to improve the quality of plant growth, then it can be expected that F2K1 will give higher tuber yields.Keyword: shallot, oligo-chitosan spraying frequency, oligo-chitosan concentration

Abstract

Coffee is a commodity with high value for export. Coffee bean borer (Hypothenemus hampei) is the main pest causing the decline in coffee production. Farmers still rely on chemical insecticides to control this pest. To reduce the negative impact of insecticides, entomopathogen Beauveria bassiana is applied. The research aimed to investigating the level of pathogenicity of B. bassiana in controlling H. hampei, and investigating the concentration with the highest level of pathogenicity of B. Bassiana against H. hampei. Laboratory research was arranged in one factor Completely Random Design (CRD). This research used 8 (eight) treatments namely KO: Aquades, Kk: Lamda Sihalothrin 25 EC (Chemical Insecticide), B1: 10 g / L B. bassiana cultivated in rice bran media, B2: 20 g / L B. bassiana cultivated in rice bran media, B3: 30 g / L B. bassiana cultivated in rice bran media, B4: 10 g / L B. bassiana grown on corn media, B5: 20 gL B. bassiana grown on corn and B6: 30 g / L B. bassiana grown on corn media. Each treatment used coffee beans infested with 20 H. hampei and repeated 4 (four) times. The result of the research showed that B. bassiana was able to kill H. hampei. The concentration that was able to cause the fastest mortality with a high level of pathogenicity based on the pathogenicity test of B. bassiana on H. hampei (percentage of mortality, total mortality time, and feeding capacity) was 30 g/L of B. bassiana cultivated in rice bran media.Key words: Beauveria bassiana, Hypothenemus hampei, chemical insecticide, coffee bean

Abstract

The economic value of the Abaca banana is on the trunk which contains fiber for valuable textile and paper industry raw materials. The multipurpose fiber and its prospects are quite good, so the abaca plant gets a lot of attention from various community groups both private, state-owned, cooperative and farmers. Propagation through multiplication humps is very low, planting material is easily damaged in transportation, is not durable and requires large space so that transportation costs are high. One alternative to overcome the provision of healthy, large and fast seedlings is to use seedlings from tissue culture. The aim of the study is to get the right thiamin and leaf fertilizer concentrations at the acclimatization stage. The experimental design used was a 2-factor Complete Randomized Design, Thiamin concentration (1 ml / l, 2 ml / l, 3 ml / l) and leaf fertilizer (0.5 ml / l, 1 ml / l, 1.5 ml / l). The data obtained were analyzed for diversity at 5% level and further tests using Duncan Multiple Range Test (DMRT) level of 5%. The results showed no interaction between thiamin and leaf fertilizer, Thiamin 2 ml / l gave the best results on all parameters and 1.5 ml / l leaf fertilizer could increase plant height and the number of leaves of abaca banana plants.Keywords: Thiamin, leaf fertilizer, abaca banana, acclimatization

Abstract

Drying is one of the important post-harvest activities. Limitations on the location of drying, labor and during the rainy season cause delays in drying. Delays in drying and improper seed layer thickness can reduce the quality of the resulting seed. The purpose of this study is to determine the time delay for drying and the maximum thickness of the seed that did not reduce the viability and growth of rice plants. The study used the innovation drying floor of UPT BBP Barongan, Bantul and Split Plot Design with 2 factors. The first factor as Main Plot was the treatment of drying delay: 2.4 and 6 days. The second factor as a sub plot is the thickness of the seed layer: 3, 5, 7, and 9 cm. The treatment is repeated 3 times. The research data were analyzed with Analysis of variance 5% and further tested with DMRT 5% (Duncan's Multiple Range Test). The results showed that the treatment of delaying drying for up to 6 days and the thickness of the seed drying layer up to 9 cm can be tolerated with innovative drying tools so it does not reduce the seed vigour and growth of rice plants. Keyword: drying delay, seed layer thickness, innovation drying floor, rice vigour and growth
