Abstract

The increment of peat soil productivity meets through ameliorant addition. Ameliorant sources can be obtained from oil palm plantation and electric steam power station waste. The study aimed at investigating the ability of the oil palm fruit empty bunch (OPFEB) biochar, palm oil boiler ash (POBA) and coal fly ash (CFA) as alternative ameliorants besides compost to improve nutrient availability in peat soil of Central Kalimantan. Treatments tested were OPFEB biochar, POBA, CFA, compost, OPFEB biochar+compost, POBA+compost, and CFA+compost. The seven treatments were arranged in a completely randomized design of single factor with four replications. The results revealed that the ameliorants increased peat soil pH at a rate of 0.7 compared to those in initial soil used and available P of 135.7% even though there was no significant increment of exchangeable cations of K, Ca and Mg. Mixing of biochar, POBA or CFA with compost improved nutrients availability in peat soil.

Abstract

Arut Bawah is a settlement that is always flooded every year due to Kahayan river run off . Residents perform various activities on the water, and transportation between housing residents with one another, using wooden boards. The conditions is not possible if it is used to grow crops. It is certainly limiting factor for household food needs, including the need for vegetables. Flooded land use around residential has not been done because the technology is not yet known. Through these activities, the community is expected to implement one of the local knowledges of the environment-friendly cultivation in swampy areas with ambul system so that people can still grow crops to sustain life. It consists of meeting nutritional needs, as well as improving food security in water-saturated soil conditions. This community service was conducted by the various stages of 1) outreach and dissemination of technology ambul 2) training of making ambul and 3) planting a variety of vegetables in ambul. The results showed that ambul can be used as a technology for cultivation in flooded areas. The introduction of technology ambul got a positive response from residents Arut Bawah Palangkaraya Central Kalimantan. Keywords: ambul, vegetables and flooded areas.

Abstract

Cultivating of melon particularly in Central Kalimantan has been widely undertaken by farmers, however, the yields have not been able to meet the melon needs of Central Kalimantan's community. One of the breakthroughs in overcoming the problem is by growing melons on swamp floating beds, namely ambul technology. Ambul is growing media from decomposed floating aquatic plants, constructed with bamboo or wooden as a frame, that is let floating on waters. The ambul based on the consideration that the community lacks access to land for most of the year, which reduces opportunities for growing crops. The research design used was Split Plot Design with three kinds of aquatic plants as the main factor namely Eichornia crassipes, Salvinia molesta, Eleocharis palustris, and two melon varieties as subplot factors specifically Action 434 and Amanta. The results showed that the Amanta variety grown on S. molesta media produced the highest value of crop length on 1, 2, 3 weeks after planting (WAP). S. molesta was the best planting media for enhancing flowering by 11.43 days after planting (DAP) and weight of fruit (3.18 kg per plant. The variety of Amanta also had the highest value of root dry weight of 1.33 g per plant and fruit weight of 2.08 kg per plant.
