Metal cookware has been used many people for its better thermal conductivity. However this material also has some weaknesses for its reaction with acidic food which will contaminate the food. Metal-base material coated with enamel is one of the solutions. The hard and non-reactive surface has cause this material has been widely used for processing food. Lower thermal conductivity is one of the problems of enamel cookware. The experimental analysis has been conducted to investigate energy efficiency, emission rate and thermal conductivity. The efficiency is calculated by comparing the useful energy (work) with the input energy. The emission rate is calculated by multiply energy consumption with emission factor. Meanwhile the thermal conductivity is calculated by using simply conduction heat transfer equation. Based on the analysis, enamel cookware has much lower thermal conductivity than aluminum cookware. However this physical property does not much affects the efficiency. The most dominant factors which should considered are type of fuel and technology of stove which consume higher energy inefficiently and emits much higher hazardous gas

Bentonite, especially Sodium (Na) Bentonite is a type of clay that is used as a basis for water-based drilling mud in the of oil and gas wells drilling throughout the world including Indonesia, bentonite used in Indonesia is still partially imported from abroad. Sodium Bentonite can be substituted with ordinary clay which is treated by beneficiation throught addition of Na2CO3. The area of Musi Rawas Utara (Muratara) Regency of South Sumatra Province contains clay reserves resulting from pyroclastic deposit which will be investigated as potential subtitutional materials of imported API Bentonite. Clay samples from 6 different locations were prepared by first looking for the best % swell of sample beneficiation combination from all over the 36 combinations through the free swell test, the results obtained that the 4% BWOC Na2CO3 combination gave the best % swell. From this, 24 samples were prepared for various measurements of mud properties using standard equipment and procedures following the API RP 13 B for water-based mud with drilling grade Na-bentonite (API Bentonite) as standard material. The test includes 7 properties which are divided into 16 measurement units namely density, rheology, filtration, solid and liquid content, sand content, pH and methylene blue capacity etc. The test results show that the Na2CO3 beneficiation is able to change ionically the characteristics of the clay, but from the aspect of the suitability of the value of each test parameter to the standard value shows that none of the samples has full compatibility, which is mean that Muratara clay technically cannot be used as a substituent material of API Bentonite.

The aim of this research was to find out the effect of substrate concentrations (COD) of vinasse and the length of fermentation time to bio-hydrogen gas production using agent fermentation of photosynthetic bacteria, Rhodobium marinum. The production of bio-hydrogen was examined by varying COD of vinasse (10,000; 20,000; 30,000; 40,000; 50,000 mg COD/L) at certain fermentation time in the third, sixth and ninth day. The highest Hydrogen gas was obtained at ninth day of fermentation (82.66±18.6 mL). The highest Hydrogen Production Rate (HPR) and COD removal rate were obtained at concentration 50,000 mg COD/L, namely 109.98 mL H2/L/d and 1437.66 mg COD/L/d, respectively. Thus it can be concluded, the concentration of substrates (COD) from vinasse and the length of fermentation time have an effect on production of bio-hydrogen gas using Rhodobium marinum

The existence of irrigation canals greatly supports the production of rice produced, where irrigation channels will be equipped with embankment to protect irrigation channels. Existing soil must certainly be able to withstand shear strength to withstand embankment, while the soil in the South Sumatra region, especially the swamp area has a low shear power so it cannot hold back the shear strength from the embankment. For this reason, it is necessary to research the shear strength of the soil in the swamp area by adding fly ash and petrasoil in order to get the effect of increasing the value of the soil shear strength in the swamp area. The tests consists of the seive analysis, index properties, atterberg limits, soil compaction, and shear strength testing, based on SNI and ASTM. Mixed variations consist of 5, namely: (i) soil + petrasoil; (ii) soil + 10% fly ash + petrasoil; (iii) soil + 15% fly ash + petrasoil; (iv) soil + 20% fly ash + petrasoil; (v) soil + 20% fly ash; all variations without ripening. The test results are obtained that addition of 10% fly ash + petrasoil could be increase the soil cohesion value that is 21.56 Kpa, while the variation of the addition of 20% fly ash + water was obtained the highest value of the shear angle, that is 32.31 Kpa.

Spirulina platensishas been well-known as an abundant protein and phycocyanin. Spirulina platensis has the effect of anti-inflammatory, so it is widely used to apply cosmetics and biomedicine in the healing process of wounds. To prove that the administration of an extract ofSpirulina platensiscan increase the number of fibroblasts and accelerate the wound healing process in Wistar rats with an incision on their skin. This study used a randomizedpost-test only control group design. The skins of thirty (30) male Wistar rats were incised. This treatment was divided into 4 groups, namely the group that received the 0,1% cream (X1) of S.platensisextract, and the group that was administered with the 0,1% ointment (X2) of S.platensis extract; the negative control group was only treated by a saline solution (C1), and the positive control group was with the administration of Gentamycin 0,1% ointment (C2). The total numbers of fibroblasts were examined on day 14 and calculated using the method of tissue biopsy and hematoxylin-eosin (HE) staining. The wound was checked after 14-day Data analysis was performed with a one-wayANOVA test and was continued by Post Hoc Test LSD. The total numbers of fibroblasts on day 14 from the group of XI, X2, C1, and C2 were 15.00; 17,50; 3,83, 10,33 with p<0.001. The average size of the wounds on day 14 from the groups of X1, X2, C1, and C2 was 551,78; 435,76; 1795,95; 1193,57 with p<0.001, respectively. PostHoc Testresults on the total number of fibroblasts and extensive wound area showed significant differences between them. Administration of the 0.1% ointment of Spirulina platensisextract believed to potentially increasing the number of fibroblasts and accelerate the process of wound healing.
