Abstract

The development of coconut as one of the prime commodities in Central Kalimantan is required to contribute national export needs. The results of analysis and evaluation of landsuitability indicated that at regional level of Central Kalimantan, the land suitability class for coconut is class S3 (marginally suitable). The main limiting factors found in wetland typology include presence of peat, drainage, nutrient availability and soil acidity. Whereas on dry land is soil acidity, slope and nutrient availability. The results of further spatial analysis explain that the potential areas for the coconut commodity development in Central Kalimantan is 3,499,712 Ha or 22.65% of the total areas. Spatially, the potential of development areas are spread within almost every district. There are 2 areasthat is not designated for coconut development, namely the city of Palangka Raya and Murung Raya regency due to limiting factors existence such as sandy soil type and steep slope (> 30%). Regional development strategies for coconut commodities can then beallocated to areas that have abandoned land areas. While at areas surrounding by settlements, they can be implemented by the use intercropping farming systems at the age of coconut growth for less than 3 years n order to optimize the land resources and climate productivity while at the same time increasing the income.

Abstract

Root rot disease caused by the Ganoderma boninense fungus is a serious problem in oil palm cultivation. Initially this disease attacks mature plants, plants of the 3rd generation; but at this time Ganoderma disease has attacked immature plants and nurseries. Ganodermapathogens are soil borne. Improvement of growing conditions needs to be improved with the application of chemical fertilizers and the use of biological agents such as Trichoderma and Mycorrhizae. This study aims to determine the resistance of oil palm seeds with KCl, Trichoderma, and Mycorrhizal fertilizer treatments. The Ganoderma inoculum is infused in the form of a Rubber Wood Block (RWB). The research design was a factorial randomized block design consisting of 3 treatments, namely Trichoderma (T0, T1,T2), Mycorrhizae (M0, M1, M2), and KCl fertilizer (K0, K1, K2). There were 18 treatments with 3 replications. Observation parameters were seed height, number of leaves, roots, and attack intensity. The growth of seedlings at the 3rd and 5th months showed that the growth of seedlings was due to Ganoderma infection. Trichoderma and mycorrhizal treatment increased the number of healthy roots and crown dry weight. The treatment of KCl fertilizer only plays a role in root health. The best treatment is T1M2K1.Keywords:

Abstract

The use of microbes as bioremediation agents is an alternative strategy to reduce residual or pesticide resistance. This study utilized rhizosphere microbes from various land covers as isolates. Soil samples used came from the rhizosphere of papaya, bamboo, peanuts, rice fields, maize, sweet potatoes, forest plants, cucumbers and guava. Isolation was carried out using Minimum Salt Agar (MSM) media which added 50 and 100 ppm of pesticide or herbicide. Microbes that were able to grow at a concentration of 100ppm were used as the selected isolates. Furthermore, the isolates were characterized by morphology and physiology such as; gram test, motility, pathogenicity, oxygen demand. As well as testing the microbial activity of selected isolates on the soil through a soil respiration test contaminated with herbicides and pesticides using sterile soil. A total of 5 selected isolates were used in the respiration test, namely with the code JMH, SH, HH, JP and TP. Of the 3 isolates that have the potential to degrade pesticides, the isolates with the JP code of 15.6 mg C-CO2 / g / day produced the highest respiration value. Meanwhile, of the 2 isolates had the potential to degrade herbicides, the isolates with the SH code of 9.6 mg C-CO2 / g / day produced the highest respiration value. These isolates have potential as biodegradation agents for pesticides and herbicides, so it is necessary to continue for further analysis regarding quantification and the mechanism of biodegradation.

Abstract

The area of dry land in Indonesia is quite high, reaching 148 million hectares spread across each of the Indonesian archipelago. Usually farmers plant dry land with rice, palawidja or other annual crops such as coconut, cassava and tree crops. Dry land has constraints, namely limited water for plants, especially in the dry season, because it only relies on water from mere rain sources; that is why land productivity is not optimal which in turn will have an impact on crop yields. The purpose of this study is to examine the harvesting run off in dry land, and can be managed as a source of irrigation water, so that productivity and carrying capacity of land can be increased. The research method uses descriptive analytic survey method that observes field conditions, mapping field locations and analysis of potential run-off. The results showed that the pool harvesting surface runoff during the rainy season was 43 m3. Dry land can increase IP of 2 by planting patterns, namely sweet corn -sweet corn -sweet potato. Water balance analysis shows that the water deficit period occurred in May to September. Surface harvesting technology as a source of irrigation water can meet water needs in the dry season.
