leaf suweg as a product of tea form believed be efficacious antidiarrheal so potentially as a funcional beverage. This research aims to know the physical and chemical character of tea-leaf products suweg packed in the form of sac. The product is divided into 5 types of formula such as F0 (100% tea powder), F1, F2, F3 (25%, 50%, and 75% suweg leaf substitution) and F4 (100% suweg) with 4 replications respectively. The results showed that the chemical properties of moisture content, ash content, and crude fiber content were not significantly different between the various formulas, while the highest tannin content was shown by F1 (p< 0.05). Physical test result that the state of steeping has met the SNI standard of tea powder where all formulas dissolveperfectly in water at 100C. The physical color test of steeping shows the sequence of dark brown (F0), faded brown (F1), brownis green (F2), green (F3) and clear green (F4). It can be conclude that the suweg tea product produced in this study have the same chemical characteristict with tea products in general except tannin conten, with he quality.keywords : tea, greentea leaves, suweg, functional drinks

Cogon grass (Imperata cylindrica), an invasive, unwanted grass was used and evaluated for its applicability for the sorption of engine oil. Other than dried and ground for smaller size, no notable treatment was performed on the cogon grass. The physical and chemical properties of cogon grass were characterized by ash content, bulk density, pH slurry, and Field Emission Scanning Electron Microscopy (FESEM). The oil sorption was performed in a batch adsorption system. The effects of contact time, dosage of adsorbent and oil retention were investigated. The bulk density and ash content of the prepared carbon was 0.34 g/ml and 7.80 %, respectively. The pH slurry value was near neutrality (6.48). FESEM micrograph of cogon grass showed jagged and rough surface. FTIR spectra revealed the presence of aromatic rings of lignin and some aromatic compounds associated with CH. Carbon, hydrogen and nitrogen (CHN) analysis revealed that 41% of cogon grass consists of carbon. The cogon grass was observed to wet oil almost instantly with sorption equilibrium time of 5 min. The dose of cogon grass was found to slightly affect the sorption capacity. Oil retention experiments reveal the good ability of cogon grass to hold oil with about 96% retention after 24 h dripping. This study may provide an insight on the usefulness of cogon grass for removal of engine oils.

Optimization of Ash Content on the Synthesize of Vulcanized Jarak Pagar (Jatropha curcas) Oil         Developments in the preparation of rubber compound formulations should be followed by a rubber compounder, especially in modifying the formula. Rubber compound composed of rubber as an elastomer and its chemical. Each ingredient has a specific function and influence to the properties of rubber articles. The research studied the formulation of vulcanized oil of Jatropha curcas to obtain the best quality in terms of ash content. The experiment begins with the characterization of Jatropha curcas oil and testing of ash content of each component in the formulation of vulcanized Jatropha curcas oil. The results was used as the basis for formulation of vulcanized Jatropha curcas oil components. Vulcanized Jatropha curcas oil was synthesized at the laboratory scale (100 g oil / batch) at 140OC temperature, agitation speed of 100 rpm, and the variation of dose Na2CO3 and ZnO (0.25; 0.50, and 0.75 pho). Vulcanized Jatropha curcas oil obtained were analyzed for visualization of physical and chemical properties. The experimental results showed that the lowest of ash content of vulcanized Jatropha curcas oil was of 1.24% obtained from the reaction by the addition of 0,25 pho of Na2CO3 and 0,50 pho of ZnO. This dose was defined as the optimal dose because it gived the ash content that meets the requirements of commercial vulcanized oil (max 1.5%).Keywords: Rubber compound, elastomer, Jatropha curcas oil ABSTRAK        Perkembangan teknik formulasi dalam penyusunan kompon karet harus dapat diikuti oleh rubber compounder terutama dalam memodifikasi formula tersebut.

Combined application of biochar and nitrogen (N) fertilizer has the potential to reduce N losses from soil. However, the effectiveness of biochar amendment on N management can vary with biochar types with different physical and chemical properties. This study aimed to assess the effect of two types of hardwood biochar with different ash contents and cation exchange capacity (CEC) on soil N mineralization and nitrous oxide (N2O) production when applied alone and in combination with N fertilizer. Soil samples collected from a temperate pasture system were amended with two types of biochar (B1 and B2), urea, and urea plus biochar, and incubated for 60 days along with soil control (without biochar or urea addition). Soil nitrate N, ammonium N, ammonia-oxidizing bacteria amoA gene transcripts, and N2O production were measured during the experiment. Compared to control, addition of B1 (higher CEC and lower ash content) alone decreased nitrate N concentration by 21% to 45% during the incubation period while the addition of B2 (lower CEC and higher ash content) alone increased the nitrate N concentration during the first 10 days. Biochar B1 also reduced the abundance of amoA transcripts by 71% after 60 days. Compared to B1 + urea, B2 + urea resulted in a significantly greater initial increase in soil ammonium and nitrate N concentrations. However, B2 + urea had a significantly lower 60-day cumulative N2O emission compared to B1 + urea. Overall, when applied with urea, the biochar with higher CEC reduced ammonification and nitrification rates, while biochar with higher ash content reduced N N2O production. Our study demonstrated that biochar has the potential to enhance N retention in soil and reduce N2O emission when it is applied with urea, but the specific effects of the added biochar depend on its physical and chemical properties.
