Abstract

One type of land in a swamp ecosystem that has a lot of complexity is acid sulfate soils. One of the factors that can improve the condition of this soil is the use of organic material which functions to maintain soil redox and can chelate Fe2+. The purpose of this research was to know the effect of rice straw compost on ferro-iron solubility, soil pH, and rice growth so it obtained the appropriate treatment of the dose of rice straw compost. Soil sampling of acid sulfate soil was collected in Jejangkit District, South Kalimantan. This research was conducted in the greenhouse of Agroecotechnology Study Program and set up with a completely randomized design with a single factor. The treatments were K0: control, K1: soil + straw compost 2,5 t ha-1, K2: soil + straw compost 5,0 t ha-1, K3: soil + straw compost 7,5 t ha-1, K4: soil + straw 10,0 t ha-1, with 3 replications. The results showed that the dose of straw compost treatments was not significantly affected on Fe2+ iron solubility, number of tiller, wet and dry weight of rice plant, but showed a significant on soil pH. The best treatment of rice straw compost is in the treatment with 5 t ha-1 of dose because it can increase the highest pH of 3,72 and can reduce Fe2+ content to 54,82 mg kg-1. Tiller number, wet weight, and dry weight of rice plants were not significantly different because the plant runs into a limitation of growing.

Abstract

The availability of banana seeds, especially Sulindang bananas as a fruit commodity in South Kalimantan, cannot be met on a large scale. The problem is that Sulindang banana seeds are still produced conventionally that produce small amounts of weeds. The solution that can be done to get maximum seed yield is by tissue culture. The research aims to determine the influence of interaction between BAP and kinetin on the growth of banana weevil explant Sulindang. This study used RAL two factors in the form of kinetin concentration and BAP concentration, consisting of 4 levels of kinetin; k0 = 0 mg l-1 kinetin; k1 = 1 mg l-1 kinetin; k2 = 2 mg l-1 kinetin; k3 = 3 mg l-1 kinetin and consists of 4 levels of BAP; b0 = 0 mg l-1 BAP; b1 = 2 mg l-1 BAP; b2 = 2.5 mg l-1 BAP; b3 = 3 mg l-1 BAP. The observed variables are changes in the morphology of the explant, the time the buds appear, the number of buds, the number of leaves, the percentage of living explants, the percentage of explants of contamination and the percentage of browning. The results of this study showed that there was no interaction between various concentrations of BAP and kinetin with banana explant Sulindang in the in vitro growth response in MS media.  The BAP concentration did not affect the growth of the Sulindang Alas banana weevil explants. Single factor kinetin 2 mg l-1 was able to give the best results on the percentage of live explants at week 3 and week 6, respectively 96.88% and 93.75%. Also gives the smallest percentage of contamination at week 3 of 3.13% and week 4 to week 6, respectively - 6.25%.
