The need of fresh water in daily life is very important. To get fresh water from sea water can be done by distillation and desalination. Mangrove plants which grow in brackish water are affected by the stress of saline water. The research studied process of desalination by Rhizophora apiculata, Rhizophora mucronata and Xylocarpus grantum. All of those plants were six months age. Salinity, chlorinity and conductivity of water which contents sea water of 0, 25, 50, 75 and 100 percent (v/v), then the mangroves planted in every pot. The results were mangrove can decrease salinity, chlorinity, and conductivity of water, except of water which did not content of sea water. The increasing of chloride ion in the tissues was influenced by the increasing of chloride ion in root tissues of all treated plants

TEKNOLOGI PENGAIRAN DAN PENGOLAHAN TANAH PADA BUDIDAYA PADI SAWAH UNTUK MITIGASI GAS METANA (CH4)

Global warming that caused by green house effect is one phenomena where short wave sunlight radiation penetrates the atmosphere and changes to become long wave on earth surface, when reaching the earth surface, a part of the wave reflected to atmmosphere,however not the entire reflected wave will be released to outer space; greenhouse gases layer in the atmosphere will reflect part of the wave to the earth surface resulting in increasing surface temperature.According to data from National Communication in 1997, agriculture and husbandry sectors give large contribution for the increasing green house gases particularly CH4 produced from rice field cultivation.Due to the reason, research for and soil cultivation technology on rice field for mitigation of methane (CH4) gas emission in dry season has been conducted. The objectives are to analyze different effect of continuously flooded (5 cm), intermittent irrigation and saturated water condition (0 - 1 cm water level) on CH4 emission, to analyze effect of soil cultivation and zero tillage on CH4 emission and to analyze interaction between irrigation treatment and soil cultivation on rice field for CH4 emission.The result indicated that type of irrigation systems affect the CH4 emission on rice field cultivation. Intermitten irrigation system shows able to suppress CH4 emission 56.34%, while saturated water condition system is 54.61%. Type of soil cultivation also affects the CH4 emission. Soil preparation with zero tillage by touchdown reduced CH4 emission by 25.55%, while by gramoxone the reduction was 48.84%. The lowest CH4 emission was under saturated water condition system combined with zero tillage treatment. Combination saturated water condition system by touchdown and zero tillage treatment is resulting emission in amount of 61.54 kg/CH4/ha/season. The combination of saturated water condition system by gramoxone and zero tillage treatment is resulting emission in amount of 88.12 kg CH4/ha/season.Combination of all treatment has no significant difference on rice yield.

Effect of Liquid Organic Fertilizer from Nata de coco Waste and Cow Manure in Anaerobic Digester Processing Application in Soil Chemistry Properties of Lettuce Planting ABSTRACT . The objective of this experiment was to study effect of liquid organic fertilizer from nata de coco waste and cow manure in anaerobic digester processing application in soil chemistry properties of lettuce planting. The experiment is conducted at Physical Chemistry and Environmental Laboratory of IPB and in Jabon Mekar Village, Parung, West Java. The treatment of this experiment is application of liquid fertilizer (organic fertilizer) once, twice, and three time a week from effluent anaerobic digester 75% nata de coco waste + 25% cow manure, 50% nata de coco waste + 50% cow manure, 25% nata de coco waste + 75% cow manure, and 100% cow manure compared with control (inorganic fertilizer) on lettuce. The result showed that the application of liquid organic fertilizer from nata de coco waste and cow manure in anaerobic digester processing can increase the soil chemistry properties.

Pemanfaatan Lemak Tengkawang Sebagai Subtituen Malam pada Pembuatan Lipstik

Paten dan Invensi (Granted) (2002)

Erliza Hambali Irawadi Jamaran M. Sri Saeni Tun Tedja Irawadi Ani Suryani

Pemanfaatan lemak tengkawang (Shorea spp.) telah dikembangkan oleh IPB sebagai substituen malam pada pembuatan lipstik. Selama ini sebagian besar lemak tengkawang hanya digunakan untuk meningkatkan titik leleh lemak coklat pada industri coklat. Pemanfaatan dilakukan melalui proses pemurnian lemak tengkawang dalam beberapa tahapan yang menghasilkan lemak pucat untuk digunakan sebagai pensubstitusi malam secara parsial dalam pembuatan batang lipstik. Teknologi proses pembuatan lipstik tidak berbeda dengan teknologi pembuatan lipstik yang telah ada; bahan baku menggunakan lemak tengkawang pucat mudah didapat; biaya produksi pembuatan lipstik dengan menggunakan lemak tengkawang menjadi lebih rendah. Nomor Paten: P00200200546 (ID P 0029922)

The objectives of this research were: 1) to find out whether acid rain has taken place in Bogor Regency area and its effect on the lead (Pb) content in soil and roughage in the region, 2) to predict the correlation of Pb content in rain water and soil, and the content of Pb in roughage in the Bogor regency area, 3) to study the impact of acid and Pb content in the ration to sheep daily gain and measure Pb content in liver, kidney and meat. The results showed that in Bogor regency area the acid rain occurred during the dry season but not in the wet season. The Pb content in the rainwater and soil were not affected by acid rain. There was no correlation of Pb content between soil and roughage. Acid containing ration decreased daily gain, but not for the ration of high Pb-content. Acid containing ration increased Pb content in the kidney but not in the liver and meat. However, high Pb content in the ration increased the Pb content in the liver and kidney but not in the meat.
