Abstract

Sunaryanto et al, 2019. Optimization of Penicillium lagena Medium Cultivation on Antifungal Pathogen of Phellinus lamaoensis using Response Surface Methodology. pp. 410-420. Phellinus lamaoensis (Murr.) Hein is fungal pathogen that can cause brown root rot disease in cocoa, tea, rubber, and coffee plants. Endophytic fungi, Penicillium lagena, isolated from bandotan (Ageratum conyzoides Linn.), medicinal plant, is able to inhibit the growth of pathogenic, P. lamaoensis. The effect of carbon source, nitrogen source, and mineral solution was studied. Lactose, yeast extract, and mineral solution were media components which showed significant effect toward production of P. lagena active compound. Composition optimization of these three medium components was done by response surface methodology (RSM). The Optimal response region of the significant factor was predicted by using a second order polynomial model with statistical design, central composite design (CCD). Higest production of P. lagena active compound by quadratic model was predicted to be 69.233% with medium composition 44.77 g L-1 lactose, 13.02 g L-1 yeast extract, and 15.95 mL L-1 mineral solution. Verification value in laboratory is 58.365%, lower 15.7% than its prediction. Optimization increase P. lagena active compound 9 fold compared to unoptimize media.

Abstract

Mawardhi et al, 2019. Strategy on Peatland Utilisaton through Development of Coffea Liberica Agroforestry. pp. 43-51.Agriculture development in Indonesia has been shifted from fertile land to suboptimal land, as example peatland. Area covered by peatland in Indonesia are approximately 14,9 million ha, which about 52% of the land are potentially for agriculture. There is limitation for farmer to cultivate various crop because of peat soil characteristic which less support for plant growth. Coffea liberica is one of plantation comodity which can survive and productive in peatland, so that it recomended as main comodity in peatland region. Farmers in Jambi, Riau, and South Sumatera have been developed coffea liberica agroforestry on peatland. Its product sold to local market and other countries, such as Malaysia and Singapore. Coffea liberica production should be increased to meet market demand. Coffea liberica development supported by internal strength i.e. a) planting material supply, b) labour, and c) land farming; and opportunity i.e. a) market information access and b) coffee product price. In other hand, technology competence is a weakness that limited coffee farming. Technology inputs on coffee liberica include recomended variety, population management, fertilisation, pruning, pest and disease control, and drainage control. Those aspects showed that development model of coffee liberica agroforesty based on technology was the appropriate strategy of peatland utilisation on plantation.

Abstract

Pujiastuti et al, 2019.The Existence of Insect Species in Various Intercropping Vegetable Crops: Case Study in Talang Pasai Village, Pagar Alam Utara District, Pagar Alam City South Sumatra. pp. 103-109.Intercropping plants are a cropping system that is widely applied by farmers ie planting more than one species of plant. In addition to increasing crop production, intercropping systems are also optimize land functions. Intercropping systems are also wellknown to affect the diversity of insects that live or visit plants. The aim of the study was to identify insects  living on plants or around plants and their role in intercropping systems. Research had been carried out in the highlands in the North Pagar Alam District, Pagar Alam City, South Sumatra, in July-August 2018. Insect observation methods were conducted by direct observation and hand picking. Observations were carried out 3 times with 1 week observation interval. The types of intercropping observed included red onions, chili-celery, chili-cabbage and eggplant-carrots. The results of observations on plants intercropping in which  chili plants as one of the crop showed chili plants were more visited, seized or attacked by insects compared to their partner plants. In the chili-red onion plants, it was  found 4 orders, 5 families and 6 species, in chili-celery plants found 4 orders, 5 families and 10 species, in chili-cabbage plants found 5 orders, 6 families and 8 species, whereas in the eggplant-carrot plants found 5 orders, 11 families and 13 species. Intercropping with chili plants shows that their partner plants are less attacked by pests.

Abstract

Purbiyanti et al, 2019. Potency of Toman Cultivation (Channa micropeltes) in Komering River as the Additional Income of Swampy Rice Field Farmers’ Household. pp. 333-337.The potential of many rivers stretched in South Sumatra is a great potential for the development of freshwater fish culture. One of them is Toman (Channa micropeltes) which is a type of fish from the “gabus” fish. Toman has economic value and is highly nutritious, and is easily cultivated. The community in Arisan Buntal village, Kayu Agung subdistrict, began to cultivate this fish as an additional source of income; outside the wetland swamp rice farming as the main source of income. This study aimed to analyze the income of Toman cultivation in Arisan Buntal village. Quantitative approaches were used in this study. The sampling method was carried out by purposive sampling, technically interviewing the peat swamp rice farmers who also cultivated the Toman fish. A sample of 8 farmers was obtained. Data consists of primary and secondary. The results of data processing show that the average farmer is only limited to cultivating Toman fish as much as 1 cage. The seeds are distributed around 1,000-1,200. The net income received by farmers reached Rp. 11,976,000 / cage / 8 months. The community calls this business "savings in the water". Even though the marketing of Toman fish is relatively easy, the farmers are enough to find collectors they already know; however, there are still some obstacles in the cultivation. These constraints include: high feed costs; fish susceptible to death or loss due to being stolen during maintenance; pollution in the Komering River due to canals from oil palm plantations that flow into the river; and lack of experience of farmers because it is still relatively new in cultivating it. Given the magnitude of the cultivation opportunities and nutritional value of these fish, farmers should increase their business scale. This is done to increase income; also to increase the nutritional value of the farming family in particular. It is hoped that the regional government can support the cultivation of the Toman through the launching of the flagship program of Ogan Komering lirI Regency; and also eliminating existing constraints.

Abstract

Suparwoto et al, 2019. Adaptation of Inpari and Inpara Varieties in Shallow and Middle Swampy Lands  in the Berkat Village  Ogan Komering Ilir District, South Sumatra. pp. 13-20. Varieties are one of the most environmentally friendly, safe and low-cost technologies that farmers can reach in increasing national rice needs, in order to keep pace with the ever-increasing population growth. This activity is conducted in Berkat Village, Sirah Pulau Padang Subdistrict, Ogan Komering Ilir District (OKI), Sumatera Selatan, in dry season of 2016. The purpose was to obtain varieties that could adapted in shallow swampy lands and middle swampy lands with high production. Inpari 15, Inpari 22, Inpari 30 and Inpara 4 are labeled purple (SS class), urea fertilizer, SP-36, KCl, pesticide, herbicide and tarpaulin. In addition the required tools include: hand tractor, meter, scales, machetes, hoes, sprayer. The varieties studied were 4 varieties consisting of Inpari 15, Inpari 22, Inpari 30 and Inpara 4. The method used direct observation in the field, assessment area of 0.5 hectare, each typology 0.25 ha. Fertilizer dosage 150 kg Urea, 100 kg SP-36 and 100 kg KCl / ha. Nursery done 2-3 times moved to adjust the water level so the age of the seedlings reaches 45 days after spread. The variables observed were: plant height, number of productive tillers, panicle length, number of grains per panicle, the number of filled grain per panicle, and production. Observational data are tabulated and analyzed descriptively. The results showed  that the production of Inpari 15, Inpari 22, Inpari 30 and Inpari 4 grains in shallow swampy lands ranged from 3.4 to 3.8 tons gkp / ha, better than the production of middle swampy lands, ranging from 2.2 to 2.9 tons gkp / ha, because the swamp in the middle reaches dryness.

Abstract

Purwanti et al, 2019. Bionematicidal Effects on the Attack of Root-Knot Nematode Meloidogyne incognita (Koffoid & White) Chitwood at Several Doses. pp. 198-205.Biological control by utilizing antagonistic fungi is an alternative control of root-knot nematode (RKN) which does not damage the environment.  Giving organic material to the soil can increase soil fertility and support the success of biological control.  Bionematicides in the form of manure compost enriched with antagonistic fungi at the right dosage are expected to be able to control the attack of root-knot nematodes and increase tomato growth and production.  The aim of the study wass to determine the effect of bionematicide treatment on chicken manure compost enriched with antagonistic fungi from South Sumatra lowland vegetable crops at various doses in controlling the attack of root-knot nematodes on tomato plants. The bionematicide in the form of  chicken manure compost with Aspergillus 2 fungi and Trichoderma  has a high potential in suppressing root-knot nematode attacks.  Increased bionematicidal dose decreases the amount of nodule formed at the roots of tomatoes. Bionematisidal treatment in the form of chicken manure enriched with Aspergillus 2 and Trichoderma fungi at a rate of  300 g  10 - kg of soil produced the lowest amount of the purse on the root with the highest growth and tomato production.
