Coconut oil in West Kalimantan is still largely a traditional coconut oil because it has not gone through a refining process. To improve the quality of traditional coconut oil, the addition of activated charcoal can be used as an adsorbent so as to improve the quality of coconut oil. Activated charcoal can be made from materials that contain high carbon, one of which is a coconut shell. The purpose of this study was to determine the effect of adding activated charcoal to improving the quality of traditional coconut oil and the concentration of adding activated charcoal that produced the best characteristics of coconut oil. The research design used was a Randomized Block Design with one factor (coconut shell active charcoal concentration) 6 levels of treatment (0%, 1%, 2%, 3%, 4%, 5%) with 4 replications. The data obtained were analyzed using ANOVA (ɑ = 5%) if there was an influence followed by BNJ test (ɑ = 5%). The results showed that the addition of coconut shell activated charcoal with a concentration of 1% -5% to traditional coconut oil can significantly reduce free fatty acid levels. In addition, the addition of activated charcoal affects the sensory attributes of color and aroma to be better than the control (without the addition of activated charcoal). The best traditional coconut oil produced in this study is traditional coconut oil added with coconut shell activated charcoal with a concentration of 5% with chemical and sensory characteristics as follows: water content 0.138%, free fatty acid content 0.428%, saponification number 231, 9 mg KOH / g, color value 4,88, and aroma value 3,68.Keywords: adsorbent, activated charcoal, coconut oil, refining, coconut shell

Grafting on tomatoes is performed to obtain tomato plants that are resistant to bacterial wilt, waterlogging resistant, resistant to fusarium wilt and nematodes. Bacterial wilt caused by Ralstonia solanacearum causes the tomatoes grown in the rainy season to wilt and die. These bacteria live in the soil and invade plants through roots. To overcome this disease, grafting was carried out by using resistant eggplant as rootstock. This method is expected to reduce the attack of bacterial wilt diseases on tomato plants. The study was conducted in the village of Penyabangan Payangan Gianyar in FY 2014. This area was located at the plateau of AEZ wet climate. The experimental design used was a randomized block design (RBD) with two treatments and 10 replications. Materials used were tomato plants that have been joined with eggplant rootstock (grafted) and tomato plants without root stock (non-grafted) for comparison. The varieties used were varieties F1 Marta. In field applications, the scion was prevented from touching the ground while the rootstock was fully embedded into the ground. Based on the plant height, there was a  slower growth of the grafted tomato plants compared with that of non-grafted one in the early stages of growth but became normal in generative phase. It was also found that the yield of the grafted tomato was lower (2.54 kg. tree-1) than that of the non-grafted  one (3.19 kg.tree-1). Keywords: grafting; tomatoes; eggplant; stem rot;  bacterial wilt (alphabetic in order).

Abstract Cactus pear is an important species for animal feeding in the regions of dry climate. There is no information on the fertilization with coated urea in the cultivation of cactus pear under rainfed conditions in the savannah region. The aim of the current study was to evaluate the forage potential of Nopalea cochenillifera variety Doce in yellow latosol under rainfed conditions in the Brazilian savannah, comparing the fertilization with urea and coated urea in different levels. A randomized block design was adopted, in a 2 × 4 × 2 factorial scheme, with the factors corresponding to two sources of nitrogen (urea and urea coated with polymers, N+), four levels of nitrogen (0, 60, 120 and 240 kg/ha/year) and two harvests (year I and year II). The plants were evaluated after 1 year of growth, in each year of evaluation, regarding the characteristics of growth, production, chemical and mineral composition and nutritional value. The level of 240 kg/ha provided higher emission of cladodes per plant (17.33 and 18.17), respectively, for N+ and urea. The highest nitrogen use efficiency was found in the level of 60 kg N/ha (142 kg/ha/year). NFC values were 3.5 g/kg dry matter (DM) higher when the cactus pear was fertilized with urea in year I and 5.4 g/kg DM in year II. The use of conventional urea promoted better results of agronomic and nutritional characteristics of the cactus pear, under rainfed regime, when compared to the use of urea coated with polymers.
