Bark galam is part plant which remains underutilized. Hence the study was done to know compound bioaktif which is found in bark galam so bark galam could be more used especially as herbs. Screening phytochemistry analysis, the total fenol-flavonoid and the antioxidant activity performed on extract ethanol bark galam. Based on the results of phytochemical screening, compounds of secondary metabolite contained in the bark extract were alkaloid, polyphenol, flavonoid and quinone. Total phenolic was defined by using Folin-Ciocalteu method at wavelengths 748 nm and the results was 33,8646 ppm with the total of phenol level was 30,47814 mg GAE/g of extract. The total flavonoid was specified by using the method of AlCl 3 at 373,6 nm. The results showed that the total concentration of flavonoid 0,0942 ppm with the total level of extract flavonoid was 0,2826 mg QE/g of extract. The antioxidant activity test uses DPPH (1,1-diphenyl-2- picrylhidrazyl) method and the measurement uses spectrophotometry UV-Vis at wavelengths 518,90 nm. The comparison compound used is ascorbic acid. Antioxidant activity test showed that the IC 50 values in the bark extract is 44,4888 ppm. Antioxidant intensity in the bark of galam extract is included in very strong intensity (<50 ppm).","PeriodicalId":127601,"journal":{"name":"AL ULUM: JURNAL SAINS DAN TEKNOLOGI","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131720083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the engineering done is to install a mirror as a reflector that directs sunlight right into the solar panel. The factors studied were the effect of the numbers (1,2,3 and 4 reflectors) and the reflector angle (60°, 65°, 70°) on the solar panel output power, and the ratio of the power to the projection area of the installation site (power density). The method performed is with the light of the spotlight in the room, without any other light source, then measured the current and the output voltage of the solar panel. The result is that the use of reflectors has an effect on the output power of solar panels, where the highest power and density are obtained on the use of 4 reflectors at an angle of 70° (1.04 W / m 2 ), due to solar radiation collected all about the solar panel. The recommended use is 2 reflectors at an angle of 70°, with consideration of the practicality of the installation of the apparatus, and its high enough density (0.9935 W/m 2 ).

A descriptive exploratory research was conducted in rainfed rice field in Binuang Village, Binuang District, Tapin Regency, South Kalimantan Province on November 2016 to May 2017. Land preparation was done with Tepulikampar technology and the seedbed was done in two stages, i.e. dry seedbed and continued with wet nursery. Observations were made on plant height, plant age, number of productive tillers, panicle length, number of seeds per panicle, weight per panicle, weight of 1000 seeds, total weight and problems during plant growth including pests, diseases and environmental conditions. The results showed that Wojalaka black rice variety were 125 cm high and the plant age was 176 days or longer than the normal age of 127 days. Number of productive tillers is relatively small as many as 12 tillers. The yield potential is almost equal to the potential yield in the area of origin. The Banjarese planting system is less suitable to be applied to the Wojalaka black rice variety because it causes the longer period of harvest and the decrease of the harvest. The attacks of rice ear bugs and birds and diseases caused by fungus Ustilaginoidea virens also cause the decline of crop yields.
