Model Soil and Water Assessment Tool (SWAT) merupakan salah satu model yang banyak digunakan dalam penelitian pengelolaan DAS. Model ini dapat berfungsi dengan baik untuk menggambarkan kondisi hidrologi pada DAS besar dan komplek dengan berbagai skenario pengelolaan. Model hidrologi SWAT dapat digunakan sebagai alat pengambil keputusan dalam pengeloaan DAS. Penelitian ini bertujuan untuk mengevaluasi keragaan DAS Cisadane berhubungan dengan scenario sistem pengelolaan DAS dengan menggunakan SWAT. Penelitian ini membandingkan perencanaan pengelolaan DAS Cisadane yang dilakukan oleh (1) Balai Pengelolaan Daerah Aliran Sungai(BP DAS) Ciliwung-Cisadane, (2) Badan Perencanaan Pembangunan Daerah (BAPPEDA) Kabupaten Bogor dan Tangerang dan (3) Balai Besar Wilayah Sungai Ciliwung-Cisadane. Metode pengambilan keputusan, menggunakan indikator kinerja DAS meliputi koefisien regim sungai (KRS), debit jenis (Q jenis), koefisien aliran permukaan (c), padatan terlarut total (TDS) dan indeks erosi (IE). Semakin rendah nilai-nilai kriteria tersebut menunjukkan semakin baik perencanaan pengelolaan DAS. Hasil analisa menunjukkan bahwa perencanaan pengelolaan yang dilakukan oleh BP DAS Ciliwung-Cisadane (skenario 1) memberikan hasil terbaik terhadap pengelolaan DAS yang ditunjukkan oleh indikator kinerja DAS bernilai paling kecil. KRS bernilai 14,3, Q jenis mempunyai nilai 17,1, c dengan nilai 0,3, TDS bernilai33,5dan IE mempunyai nilai 2,1.

In the modern world of automation, biological signals, especially Electroencephalogram (EEG) is gaining wide attention as a source of biometric information. Eye-blinks and movement of the eyeballs produce electrical signals (contaminate the EEG signals) that are collectively known as ocular artifacts. These noise signals are required to be separated from the EEG signals to obtain the accurate results. This paper reports an experiment of ocular artifacts elimination from EEG signal using blind source separation algorithm based on independent component analysis and principal component analysis. EEG signals are recorded on three conditions, which are normal conditions, closed eyes, and blinked eyes. After processing, the dominant frequency of EEG signals in the range of 12-14 Hz either on normal, closed, and blinked eyes conditions is obtained.

Abstract Infectious diseases can occur in all parts of the body. One of the causes infection in humans is Eschericiae coli bacteria. Eschericiae coli is a rod-shaped bacteria, a gram negative bacteria, facultative aerobics and classified family member of Enterobacteriaceae from the Gammaproteobacteria class. Along the times, E.coli bacteria have resistent to some antibiotics. So we need a new alternative. There is a antibacterial substance in the isoflavon group contained in edamame. Genistein is a main isoflavon in edamame that have antiinflammation, antibacterial, and antioxidant effects. The purpose of this study was to determine is there any antibacterial effects in ethanol edamame seeds extract to E.coli bacteria. This study used a true experimental research design in vitro with a post test only control group design. The average diameter results of the inhibition zone were analyzed using the Kruskal-Wallis method and obtained p = 0.001 which means there are significant differences in at least two groups. After that, the Mann Whitney post hoc test was conducted and a significant difference was found in the positive and negative control groups for all groups but there was no difference in the treatment group, both groups K1, K2 and K3 for all groups. Keywords : Edamame, Antibacterial, E.coli

The number of people with diabetes mellitus (DM) in the world is 425 million in 2017. The use of antidiabetic drugs usually lasts long enough with high side effects. Therefore, an alternative treatment with lower side effects and the efficacy same with synthetic drugs is needed. One of alternative treatment is apple fruit which can be processed into apple vinegar. Several studies have found the hypoglycemic effect of apple cider vinegar in various dosages. The author wants to know the reduction of blood glucose levels and the effective dose of apple vinegar in reducing blood glucose levels in mice induced by dexamethasone. The type of research is true experimental laboratories with pre and post-test with control group design. This study used 28 mice. Mice were given dexamethasone for 10 days to induce hyperglycemia. After experiencing hyperglycemia, mice were divided into 7 groups consisting of negative control group, positive control group, and treatment group of 0.0625 mL apple cider vinegar, 0.125 mL, 0.25 mL, 0.5 mL, and 1 mL. The research data obtained ΔGDP in each group. Furthermore, the reduction in glucose levels is calculated. Effective dose calculation by regression analysis using percentage reduction of blood glucose levels curve. The final results showed the maximum effective dose of apple vinegar in reducing blood glucose levels is 0.341 mL with percentage reduction of blood glucose levels is 18.6%.

Wasur National Park, located in Merauke Regency, Papua, has various vegetation that could potentially yield cajuput oil, particularly those originated from Myrtaceae family. Among those are Asteromyrtus symphiocarpa. This research aimed to analysis the quality of cajuput oil distilled from the leaves of A. symphiocarpa. Initially, some amounts of leaves sample were plucked, either in the rainy and dry season. The distillation took place in the batch kettle, and each batch was charged of 12 kg of each fresh leaves. The distillation lasted for 4-5 hours, and every 30 minutes, the distilled oil was collected cumulatively. The cajuput oil from the leaves plucked on rainy season afforded the yield of 0.16%, specific gravity of 0.943, refractive index of 1.462, solubility in alcohol 1:1, optical rotations -5.2, and cineole content of 68%. Meanwhile, the corresponding value from those plucked in dry season were 0.33%, 0.912, 1.459, 1:1, -2.1, and 80%, respectively. The qualities of the overall cajuput oil from A. symphiocarpa leaves could satisfy the SNI 06-3954-2006 and belonged the main (U) class. With higher yield and greater cineole content, the cajuput oil obtained from the dry season’s leaves exhibited better qualities; hence it is more potential to be developed commercially.Keywords: Asteromyrtus symphiocarpa leaf, cajuput oil, dry season, rainy seasons.
