Durian lahung is a type of endemic durian to Kalimantan which has a unique characteristic, namely its red skin. The existence of this plant is almost extinct so that conservation needs to be done and one way is to use tissue culture techniques. As first step, it is necessary to conduct experiments to obtain the right sterilization method in order to obtain aseptic planting material. This study aims to determine the effectiveness of sterilant formulation on type of explant for lahung durian culture. This study was designed using two factors factorial Completely Randomized Design (CRD) and was repeated four times. The first factor was formulation of sterilant which consists of five levels and the second factor was type of explant which consists of two levels, i.e leaf and node. The results showed that the combination of sterilant formulation tween 20, fungicide, bactericide, Bayclin 20%, alcohol 70%, HgCl2 0,05%, H2O2 17,6% with leaf explant produced the highest percentage of browning until 4 wap. There was no browning in all combinations of sterilant formulations with node explant. The sterilant formulation tween 20, fungicide, baktericide, alcohol 70% gave the longest time to appear contamination and browning, smaller percentage of contamination and greater percentage of live explants at 2 and 3 wap, while at 4 wap it was obtained from the sterilant formulation tween 20, fungicide, bactericide, Bayclin 20%, alcohol 70%, HgCl2 0,05%. Leaf explants had lower percentage of contamination and higher percentage of live explants than node explants.

One type of popular corn now is sweet corn (Zea mays saccharata Sturt.). The high demand for sweet corn is not balanced by productivity generated. One of the limiting factors in the development of sweet corn on dry land is the low level of soil fertility. The application of lime and chicken manure are the key to improving the fertility of dry land. This research aimed to analyze the effect of the interaction and the single factor of the application of lime and chicken manure to the growth and yield of sweet corn on dry land. Conducted in Hamparaya Village of Batumandi District, Balangan Regency of South Kalimantan Province for three months, starting in August until November 2015. The design of environment that used in this study is a group randomized design (GRD), while the design of treatment is Split Plot Design. There are twelve treatment combinations were repeated three times so that there are 36 experimental plots, on each plot consisted of six plants sample so that the total number of samples was 216 plants. The results showed that the treatment interaction was not significant effect to the growth and yield of sweet corn in Bonanza F1 varieties, but a single treatment of the application of lime in dose 1,5 t ha-1 and chicken manure in dose 5 t ha-1 is the best treatment and able to enhance the growth and yield of sweet corn on dry land.

Celery is a commercial plant that should be cultivated. Nutrient Film Technique Hydroponic cultivation systems is one of the technologies that can be applied in a narrow area, but research of the planting medium and the concentration of nutrients in hydroponiccultivation system for celery plants are rare. This study aimed to analyze the influence interaction planting medium and nutrient concentrations on the growth and yield of celery. The design of this study used split plot design. The main plot were the concentration of nutrients (N): 1200 ppm (n1), 1300 ppm (n2), and 1400 ppm (n3). Subplot were the planting mediums (M): rockwool as control (m0), sawdust (m1), husk fuel (m2), and rice straw (m3). There were twelve combinations, with three replicates. The results showed that treatment interaction was not significant effect on growth and yield, but a single treatment of plant media rockwool and nutrient concentration of 1300 ppm able to increase the growth and yield of celery.
