Sorokin Guna Meningkatkan Virulensinya Terhadap Hama Crocidolomia pavonana Fabricius di Laboratorium: Addition of Several Types of Insect Flour to Metarhizium anisopliae (Metsch.) Sorokin Propagation Media to Increase Its Virulence Against Crocidolomia pavonana Fabricius In The Laboratory
Full text linkCrocidolomia pavonana is a significant pest in the Brassicaceae family. The study aimed to determine the effect of applying several types of insect flour to M. anisopliae growth media to increase its virulence against C. pavonana pests. The experimental design in this study used a completely randomized design (C.R.D.). The treatment used was A = 25 gr corn rice medium, B = 25 gr corn rice medium + 1.25 gr Hong Kong caterpillar flour, C = 25 gr corn rice medium + 3.75 gr Hong Kong caterpillar flour, D = 25 gr corn rice medium gr + 1.25 gr Kroto flour, E = 25 gr corn rice medium + 3.75 gr Kroto flour, F = 25 gr corn rice medium + 1.25 gr cricket flour, G = 25 gr corn rice medium + 3.75 gr cricket flour. The addition of insect flour could not increase the virulence of M. anisopliae against C. pavonana pests to above 50% due to less than optimal humidity conditions for M. anisopliae. The comparison of the types of insect flour used to be added to the propagation media did not significantly affect some of the parameters that had been observed, but on average, the M. anisopliae fungi propagation medium was added with insect flour made from Hong Kong caterpillars, namely treatment B (25 gr corn rice medium + 1.25 gr Hong Kong caterpillar flour) can cause the highest mortality against C. pavonana pests

Keragaman Serangga Hama dan Musuh Alami Lahan Pertanian Padi Organik (Oryza Sativa L) Desa Rowosari Kecamatan Sumberjambe Kabupaten Jember: Diversity Of Insect Pests and Natural Enemies In Organic Rice Agriculture (Oryza Sativa L.) Rowosari Village Sumberjambe District Jember Regency
Full text linkThe application of organic rice farming systems is a solution to the negative impacts of using chemicals in the application of conventional farming systems. Organic rice cultivation cannot be separated from the presence of insect pests that attack cultivated plants. Naturally, in an ecosystem that is still good, natural enemies are already present in nature without human intervention. The existence of natural enemies in a field can suppress the existing population of insect pests, so that their presence is very helpful in maintaining the balance of the existing insect pest populations. The stability of insect populations in an agricultural ecosystem is largely determined by the high diversity of insect pests and natural enemies found in a field. Thus there is a need for research on the diversity of insect pests and natural enemies as information about which insect families are found on organic rice farming land in Rowosari Village, as well as a consideration for farmers in applying appropriate control methods. This study used yellow pan trap, sweep net and vacuum cleaner insect monitoring tools. The research was conducted on 3 observation plots in the organic rice fields of Tani Jaya II Group, Rowosari Village, Sumberjambe District, Jember Regency. Observations were made 10 times from the vegetative phase to the generative phase of rice aged 7 to 77 days after planting. Observational data were then identified and then analyzed using the Shanon-Wiener Diversity Index (H), Evenness Evenness Index (E), Simpson Dominance Index (D), and Margalef Species Richness Index (R). The results showed that there were 7 families of Pest Insects found on organic rice farming in Rowosari Village, including Pyralidae, Alydidae, Grylidae, Cicadellidae, Chrysomelidae, Acrididae, and Nymphalidae. Natural Enemy Insects found were 9 families including Coccinellidea, Coenagrionidae, Gomphidae, Penttomidae, Meoidae, Miridae, Ichneumonidae, Staphylinidae, and Sciomyzidae. Neutral insects found were as many as 4 families, including Muscidae, Vespidae, Tephritidae, and Drosophilidae. The population of insect pests and natural enemies of organic rice farming land in Rowosari Village is quite balanced with a Diversity Index (H') of 2.32 and Species Richness Index (R) of 2.98, Evenness index (E') of 0.77 which is in the almost even and Dominance (D) 0.13 which means not dominating
Pengaruh Penggunaan Cacing Tanah dan Kotoran Sapi pada Proses Pengomposan Limbah Organik Pasar terhadap Kualitas Kompos: The Effect of The Use of Earthworms and Cow Manure in The Composting Process of Market Organic Waste on The Quality Of Compost
Full text linkGarbage is material that is not used or remains from activities carried out by humans, generally in the form of solids, and this is also called waste. One of the most waste-producing environments is the market, especially the traditional market. This market waste is dominated by the type of organic waste. The solution to reducing market waste can be done by managing organic waste into compost. The composting process is closely related to decomposers, examples of decomposers are earthworms, bacteria, and fungi. This study aims to determine the effect of the interaction between the treatment of earthworms and cow manure on compost quality. The study used a factorial completely randomized design (CRD) with 2 factors and was repeated 3 times. The first factor was the number of earthworms consisting of no earthworms (C0), using 60 earthworms (C1), and using 120 earthworms (C2). The second factor was the amount of cow manure which consisted of no cow manure (K0), with 22.5% cow manure (K1) and 45% cow manure (K2). The variables observed included the quality of the compost by looking at the color, smell, texture, temperature, C-organic, N-total, P2O5, K2O, and C/N ratio. Data were analyzed by Analysis of Variety. If it is significantly different, it will be tested further with Duncan's 5% Multiple Range Test. The combination of C0K0 treatment had the highest C-organic, N-total, P2O5, and K2O values. The C0K1 combination has the highest C/N ratio.. 
Analisis Variabilitas Total Nitrogen Tanah dengan Menggunakan Geostatistika pada Lahan Perkebunan Tebu Studi Kasus di Tanggul Kulon Kabupaten Jember
Full text linkPotatoes are a commodity that has high carbohydrates after rice, wheat and paddy which makes potatoes one of the most popular commodities. The high level of seed-borne pathogen infection causes decreased productivity. Tissue culture is one of the methods used to minimize the level of pathogen contamination. The acclimatization phase is a very crucial phase because at this stage it is hoped that potato plants which were previously in in-vitro conditions can adapt to the in-vivo environment. Arbuscular mycorrhizal fungi are fungi that can form a symbiosis with plants. The symbiosis that occurs is that mycorrhizae are able to produce growth hormone which can also help in carrying out nutrient uptake. This experiment was conducted using a factorial Completely Randomized Design (CRD), which consisted of two factors. The first factor is potato cultivar which consists of granola cultivar (K1) and Atlantic cultivar (K2) and the second factor is mycorrhizal dose (M) which consists of 4 levels, namely without mycorrhizal (M0), mycorrhizal dose of 1 gram (M1), mycorrhizal dose of 3 grams (M2), and mycorrhizal dose of 5 grams (M3). The experimental results were analyzed using analysis of variance (ANOVA) and if there was a significant difference, further tests were carried out using the Least Significance Diffent (LSD) test at the 5% level. Based on the experimental results, it was shown that mycorrhizal administration had a significant effect on the parameters of plant height and leaf area. The potato cultivar factor did not have a significant effect on all observation parameters. As well as the treatment of mycorrhizal factors and potato cultivars did not show any interaction on all observation parameters
