The use of aloes from natural ingredients as a drug increasingly interested in the community, along with the movement "back to nature" (back to nature) are made public. Some refiners do prior to distillation treatment by soaking the powder of aloes. Aloes contains the required components of the world's health, cosmetics and medicines. The purpose of this study was to identify the chemical components contained in the oil produced from the distillation of aloes with immersion treatment using either water or methanol. In accordance with the reading of GCMS, the distillate without immersion and immersion treatments using water produced by the component most aloes are sesquiterpene components. These components is 2 butanone, 4 phenylaceton (10.72%) and Hinesol (16.59%). Components contained in aloes by treatment with methanol immersion is Pentadecane,2,6,10,14 pristane-tetramethyl 15.96%.

Asap cair hasil pembakaran cangkang sawit pada proses pirolisis yang diperoleh pada suhu 3000C- 4000C merupakan asap cair yang terbaik yang dapat digunakan sebagai bahan penggumpal lateks. Tujuan penelitian ini adalah untuk mengetahui pengaruh suhu pembakaran cangkang sawit yang optimal melalui proses pirolisis ,sehingga dihasilkan asap cair yang dapat digunakan sebagai penggumpal lateks. Asap cair hasil pembakaran secara pirolisis pada suhu 300-4000C menghasilkan senyawa aktif yang mempunyai peranan sebagai bahan penggumpal lateks yaitu senyawa asam asetat, senyawa phenol dan pH rendah sebagai bahan anti bakteri dan jamur pada lateks.Pada suhu tersebut dihasilkan anti bakteri / anti jamur yaitu E. Colli , Staphilococus aureus dan Salmonella dengan kategori kuat dan sangat kuat. Pada suhu 300-4000C pH yang dihasilkan sebesar 2,8 dan kadar asam asetat yang dihasilkan 50,54% dan phenol yang dihasilkan sebesar 32,59% dimana kedua senyawa kimia ini sangat berpengaruh terhadap penggumpal lateks ,juga berpengaruh terhadap pertumbuhan bakteri .Kelebihan asap cair dibandingakan dengan asam formiat yang biasa digunakan sebagai penggumpal lateks adalah disamping senyawa asam asetat juga mengandung senyawa phenol yang berpengaruh terhadap pH dan anti jamur / bakteri sedangkan asam formiat hanya memberikan pH rendah dan waktu penggumpalan lateks yang cepat .

East Kalimantan province has developed seaweed aquaculture in particular, especially in the area of Bontang, East Kutai, Berau and Nunakan. The seaweed potential is quite large at around 170,000 tonnes / year (Department of Fisheries 2012). Like land plants in general, seaweed also has chlorophyll or other pigment colors. In addition, seaweed contains vitamin A and vitamin E (Sunarto, 2003). Vitamin E prevents lipofuscin, oxidized fats trigger premature aging of the skin. The purpose of this study was to determine the types of seaweed extraction method to obtain Euchema cotonii seaweed extract with vitamin E in the form of Tocopherol. Furthermore seaweed extract is added as an additive into the soap as much as 2%. Extraction technique used is the method of cold crystallization with methanol. Seaweed extract were tested using HPLC method and obtained tocopherol content 0.17 to 1.14 IU, free fatty acids 3.54%-4.42%, peroxide 4.05%-4.15%. The addition of seaweed extract as a source of tocopherols did not affect the quality of the soap produced according to standard SNI 06-3532-1994 (SNI soap)

Preserving rubber wood (Hevea brasiliensis) can avoid quality decrease that caused by termite and fungi. For preserving rubber wood we can use "Blue Vitriol (Terusi)" with sulphur copper as active material. This research used 3% and 5% concentration of Blue Vitriol, while for preserving we use a simple and pressure method. The simple method contained dyeing, varnish, and submersion of rubber wood in preserving. It pressure.method used empty cell and complete cell method, with 3 time variable of pressure, they were 0.5, 1, and 2 hours.The result of this research, concluded that the most effective simple method of preserving to avoid the attack of fungi and termite was submersion for 1 hour and 5% concentrate of preservative material. While when using pressure method the effective way was using 0.5 hour and 3 % concentrate of preservative material.

Until recently there has been no report about optimum distillation techniques, to get the time refining a relatively shorter, better yield and quality (clean and not mixed in water) (Yuliansyah, 2004). The quality and yield of oil can still be improved through improvements in the process of distillation.Before the distillation process, aloe powder immersion treatment performed for 5 (five) days using water and methanol, and then compared with the distillation without treatment (control). Distillation process carried out in conditions 2,8 to 3,5 kgf/cm2 pressure and temperature 100-110oC with a time of refining for 8 hours. Oil produced by water immersion treatment for 5 days produces a yield of more than 0,025% without immersion (control). Aloes with water immersion treatment has the test results with the same quality control and into the category of oil of Aquilaria species.

NPK fertilizer is fertilizer containing Nitrogen, Phosphate and Potassium elemen. There elements have easyly soluble in water ions and do not resist to the sun rays (heat) easyly volatility. Due to the treatment of indoor and outdoor storing, all of Nitrogen, Phosphate and Potassium elements decrease in concentration and the most significant effect of storing is the indoor storing.In the treatment of storing duration, the results of 2 weeks duration is diffferent with 4 weeks duration both for indoor and outdoor sloring. A long time storing decrease the concemretion of Nitrogen, Phosphate and Potassium in fertilizer. The result of moisture content testing of fertilizer treated with heat and rain are higher than the fertilizer stored indoor treatment.

The enqinereed equipment was simply made by comparing caouc yielded by sample with comparator colour. In the testing of free Chlor for refill drinking water the equipment reads accordingly to the standard of SNI. Its maximum reading is 0, 1 mg/l. For the value of more than 0, 1 mg/I, should be read by a titration method. This equipment production was 50% and 86,6% cheaper for the reagent then the commercial ones.
