Synthesis of Rice Husk-Based Zeolit using Hydrothermal Method and Its Detergent Builder Properties

Detergents are cleaning agents that consist of a complex formulation such as surfactants, builders, bleaching, fillers and other additives. Detergent builder that commonly used is sodium tripolyphosphate (STPP) that are unfriendly environmentally. One of the detergent builders that is more environmentally friendly is zeolite. Therefore, in the present work, zeolite was synthesized using hydrothermal method by varying the temperature and characterised its detergent builder properties. Zeolite was synthesized by mixing sodium silicate (Na2SiO3) and sodium aluminate NaAl(OH)4 with the presence of NaOH. Firstly, a mixture of sodium silicate and sodium aluminate formed sol and gradually become gel. After that, the gel had been treated by hydothermal for 7 hours at different temperatures: 500C, 1000C and 1500C. Several characteristic techniques such as FTIR and XRD were applied to identify functional group and the crystal structure, respectively. Furthermore, the detergent builder properties were characterised using cation exchange capacity (CEC) and detergency test. The result showed that zeolite synthesized at 100 0C gave better washing capability than others

Analisis Produksi Dan Pendapatan USAhatani Padi Sawah Metode System of Rice Intensification Di Kecamatan Sindue Kabupaten Donggala

This research aimed at finding out the influence of factors in line with land area factor, seed, Urea fertilizer, Phonska fertilizer, Seprit fertilizer and labours toward the production of rice field cultivated with System of Rice Intensification (SRI) method at Lero Tataro Village, Sindue district, Donggala regency. The 40 respondents were taken through census method. A multiple linier regression was used to analyze the data. The results showed that the independent variable (Xi) gave a big influence toward the dependent variable (Y). The coefficient of determination (R2) was 0.979 which means that 98 percent of the variations of rice field's production can be explained by the variable of land area (X1), seed (X2), Urea fertilizer (X3), Phonska fertilizer (X4), Seprit fertilizer (X5), and the labour (X6). The other 2 percent was explained out of the model. It can be said that farm production through System of Rice Intensification (SRI) method at Lero Tatari village were obviously influenced by the land area, seed, Urea fertilizer, Phonska fertilizer, Seprit fertilizer, and labours. The income of farm production using System of Rice Intensification (SRI) Method at Lero Tatari, Sindue district was Rp. 13.023.005.88/0.76 ha, or Rp. 17.079.351.97/ha

The problems here area (1) How is the descrition of form -la in Palembang language? (2) How is the descriptive meaning of form -la in Palembang language? (3) How is the descriptive meaning of form -la in Palembang language grammer? (4) How is correlation of using form -la with sense value and local cultural understanding in Palembang? Generally, the aim of is to describe variation of form -la in Palembang language. Theory that is used here is morphology ang semantic. Morphology theory is a science that studies about words form and the influense of form changes toward meaning groups. The approach of the research used qualitative. It is descriptive method that it can be understood as procedure series that is used in the effort of problem solving that is investigated by explaining or describing meaning in the use of particle -la in Palembang language based on the facts invisibly or as they are. The data of the research is forms and grammars in using particle -la in Palembang society for communication. Data subject in this study is community of residents in Suro, Palembang, shouth Sumatra Selatan. The result is in the description of form -la meaning can be categoriozed to be four meaning; they are, form -la as verbal abuse, form -la as notification. Also, form -la is as command, and form -la is as compression

Modification of Rice Husk-Based Activated Carbon using Sodium Lauryl Sulfat (SLS) for Lead (Pb) Ions Removal

A rice husk-based active carbon modified using SLS surfactant showed an increase on Pb ionic metal removal with the efficiency of 99.96%. Activated carbon is commonly applied as adsorben in waste water treatment, in particularly, waste water containing heavy metals and dye molecules. Even though it is commonly used, the adsorption efficiency of activated carbon to the heavy metal waste is still low. Therefore, in the present work, carbon from rice husk was modified using surfactant which further it is called surfactant modified active carbon (SMAC). Firstly, rice husk-based carbon was activated using 40% H3PO4 for 2, 6, 10, 14, 15 and 16 hours. The activated carbon was then modified by contacting it into SLS in different concentration 10, 20, 30, 40, 50, 60 and 70 ppm for 5 hours. Finally, the SMAC was then applied to remove Pb ionic metal. Moreover, several characterisation techniques were performed including FTIR, SEM, UV-Vis and AAS

Rumen Fermentation, Blood Metabolites, and Performance of Sheep Fed Tropical Browse Plants

The in vitro study was designed to evaluate total gas production, dry matter degradability (DMD), and VFA profile; while in vivo study was designed to evaluate nutrient intakes, blood metabolites, and performance of sheep fed native grass mixed with Calliandra calothyrrus (CC), Leucaena leucochepala (LL), Moringa oleifera (MO), Gliricidea sepium (GS), and Artocarpus heterophyllus (AH). The best three from the in vitro results were used to formulate diets in in vivo study. Sixteen male growing sheep (average BW 20 kg) were fed 100% native grass (NG) as control; 70% NG + 30% GS; 70% NG + 30% MO; and 70% NG + 30% AH. Nutrient consumptions, DMD, blood metabolites, and sheep performances were analyzed by using Completely Randomized Design. The in vitro results showed that the total gas production and DMD of CC and LL were the lowest (P<0.05) while the highest was found in GS, MO, and AH treatments (P<0.05). Meanwhile, the in vivo results showed that nutrient intakes (DM, CP, and CF) of GS and AH rations were the highest. The ADG, concentration of albumin, and globulin in all treatments were similar, while total serum protein, triglycerides, and glucose concentration in MO and AH rations were higher than others. Serum cholesterol concentration in MO ration was the lowest, meanwhile the concentration of IgG was the highest (P<0.05). Supplementation of 30% MO was the best choice for optimum rumen fermentation and maintaining health status of local sheep
