Research of development that held to produce student worksheet (SWS) based on valid inquiry, practice, and effective to complete courses of chemistry learning strategy. The method that used is research of development. The research used consists of four steps, namely define, design, develop, and disseminate, because the limit of time and cost, research just used until to development step. Data of research collected through evaluation sheets filled by validator. Internal validation of SWS describe that SWS writing contain indicators assessment, writing use capital letters, the distance between topic letter with information letter was different, but still used more than 10 words in line. For contain assessment can used by students with various understanding, yet include steps to find, but give various activities (read, discuss, and answer). SWS give opportunities to find different information because instruction that used in exercise requires students to read paper and another book. This activity can develop social and emotional relation, because students werediscuss in their group. Language that used has same with intellectual level of students. Format assessment describe that SWS have a title, purpose, resume, work steps, questions and include reference, also table. It requires students to implement the examples in learning activity.

Abstract: This research was conducted in order to obtain proper compositions and the standard condition for the simple filtration equipments and optimum operational conditions in adsorption column. The research was carried out by analyzing parameters COD and TSS. The result showed that the process was able to reduced parameters observed from filtration step until the process in adsorptions column. The optimum conditions for sand filter equipment were 10 cm sand height, at least 7 cm fibers, 3-4 cm gravel. In the adsorption column, the optimum conditions for green waste water were flow rate at 40 ml/min 60 min adsorptions time, and 60 cm bed height. While purple for waste water; 20 mL/min of flowrate, 60 min of adsorption time, and the 60 cm of bed heightKey words: dye solution, COD, TSS, sand filtration, adsorption column Abstrak (Indonesian): Penelitian mengenai pengolahan limbah cair hasil pencelupan benang songket dengan metode filtrasi dan adsorpsi telah dilaksanakan.

Hydrogen is viewed as one of the most potential energy source in the future. One of methods to produce hydrogen is by electrolysis of water. Variables that was applied in this work were electrical current (0.5 A and 0.9 A), pH (13.47 and 13.69), and electrolyte additions (namely NaOH and KOH) with processing times for 30 minutes. The result of this work were variations of electrical current at 0.9 A, pH at 13.69 and electrolyte NaOH is at 278.394 L with volume rate 154.663 mL/s produced most amount of hydrogen, whereas condition of 0.5 A, pH 13.47 and electrolyte KOH was 75.122 L with volume rate of 41.734 mL/s yielded the lowest amount.

Rubber seed as a biomass is potentially used as the source of alternative energy in briquette. Previous research had found that rubber seed briquette has the highest heating value of 6287,8 cal/g. It can be increased by varying temperature and mesh size. In this research, the effect of temperature and particle size on the amount of heat of rubber seed biobriquette from Muarakuang (Batu Raja) was investigated. It was done in Politeknik Negeri Sriwijaya Palembang laboratory. Proximate analysis was executed in Politeknik Negeri Sriwijaya Palembang coal laboratory. The temperature varied of 250 oC, 500 oC, and 750 oC with the particle size varied by 80 mesh, 120 mesh, and 200 mesh. Quality test of fabricated biobriquette consisted of proximate analysis such as calorific value, inherent moisture, ash ratio, volatile matter ratio, and fixed carbon ratio. The highest of heating value was 6836 cal/g from biobriquette sample were found under particle size of 80 mesh and temperature of 250 oC. The heating value reached 5371 cal/g which the particle size was 200 mesh and temperature of 750 oC. The heating value of biobriquette were compared with Indonesian National Standardization (SNI), which met with the standard of heating value (5000 cal/g).
