The assessment of river estuary physical erosion can be based on position and time distribution of velocity and sediment transport. The physical variables are partially or integratedly used to assess the flow characteristics. Analysis of the physical variables and their changes along the river estuary can show the process of sediment deposition in the estuary. Data distribution and flow physical variable profile will generate mathematical function of changes along the estuary. Spatially, this mathematical function will generate and determine the position of the material transport deposition (map of sediment deposition in along the estuary of the river). The material transport deposition map (based on the valueof (c0), presents the contours of c0 during the low tide (presented in the form of curves/full line), while the contours of c0 during the high tide (is presented in the form of dashed lines). The concentration contour of material transport at high tide is at the position of 80 meters of c0 equals 1.35 grams per litter, at low tide c0 equals 1.36 grams per litter, and at the maximum high tide, almost all sediment is in the form of fine sand sediment deposited at the position of 0 meter up to the position of 280 meters, the c0 value is equal to 1.26 grams per litter. It can be seen in the contour map the shifting position or contour lines at low tide and high tide, and when the tide is shifted farther to the upstream of shoreline. Contour lines shift to the upstream direction of shoreline at high tide shows the position shift of deposition of material transport to the upstream direction. In this condition, the concentration of sediment in the form of fine sand at the maximum high tide, almost all of it is deposited at the location next to shoreline upstream. © 2014 Maxi Tendean.

The river is a multi-resource functions that are vital to human life. The main functions of the river is a source of drinking water, power generation, irrigation fields / farms and aquaculture, transport, supply of building materials, tourism and so forth. In fact the condition of the river, discharge and water quality is even more alarming, as these resources are non-renewable. This research will be discussed further on physical variables such as changes in velocity, density, momentum and drag force, the social impact, attitudes and behavior are good in order to flood hazard mitigation and control, and the relationship between attitudes and behavior in order to mitigate hazard and flood control. Physical variable modeling analysis results showed that the increasing flood flooding the maximum velocity of the river flow will be shifted toward the surface, so with the momentum, but the density of the river water is almost evenly on all levels of the river water, but the drag force will be larger, because the drag force depends on the velocity of the river flow. © 2014 Marthen Kumajas.

The effectiveness of vegetable insecticide extracts of hutun (Baringtonia asiatica Kurz) seeds on larvae of dengue hemorrhagic fever (DHF) vector Aedes aegypti mosquito has been conducted. The test results indicate that there are differences in the real (significant) mortality level of mosquito larvae at various levels of concentration. The test result of Probit Analysis shows the LC50 mortality concentration value of Ae. aegypti larvae with the provision of concentration of 35.572 ppm is a concentration quantity value of the methanol extract of the hutun seeds which is the most effective way to kill the larvae of Ae. aegypti as much as 50% during 24 hours of treatment. According to the toxicity criteria, based on Australian Petroleum Energy Association, the concentration of 35.572 ppm of seeds hutun methanol extract or (LC50 = 35.572 ppm) at 24 hours of observation is included in the criteria for Toxic Toxicity. © 2016, Sphinx Knowledge House.

The study aims to determine the characteristics including water content, free fatty acids, peroxide number, Cu and Fe content and fatty acid profile including the content of SFA, MUFA, PUFA, omega-3, omega-6, omega 9, EPA and DHA omega-3 fatty acid concentrated microcapsule from liquid waste byproduct of tuna canning in Bitung, North Sulawesi. Omega-3 fatty acids concentrated microencapsulation with spray drying technique with encapsulation mixture consisting of gelatin, Na-caseinate and maltodextrin plus lecithin as an emulsifier. The results are omega-3 fatty acid concentrated microcapsule with a water content of 4.08%, free fatty acids of 5.66%, peroxide number of 7.56 (meq/Kg), iron (Cu) of 0.23 (ppm) and copper (Fe) of 1.05 (ppm) and the fatty acid profile containing SFA of 33.14%, MUFA of 30.79%, PUFA of 25.66%, omega-9 (C18: 1ω-9) of 19.97%, omega-3 such as linolenic acid (C18: 3ω-3) of 2.18%, the EPA (C20: 5ω-3) of 4.28% and DHA (C22: 6ω-3) of 19.19%. The characteristics of fish oil and wastewater omega-3 fatty acid concentrated microcapsule liquid waste are in accordance with the standards of the International Fish Meal and Oil Manufacturers Association (IFOMA). Urea crystallization process increases the levels of polyunsaturated fatty acids (PUFAs) such as omega-3 EPA and DHA which are used for the manufacture of omega-3 fatty acids concentrated microcapsules. The fatty acid profile of omega-3 fatty acid concentrate oil microcapsules from tuna canning wastewater byproduct is quite high, especially EPA and DHA. © 2015, Sphinx Knowledge House, All rights reserved.

Lactic Acid Bacteria (LAB) is bacteria which has an important role in the process of fermentation of organic matter. ‘Bakasang’ is traditional fermented fish product made from the guts of fish mainly Kastsuwonus pelamis L as well as other small fish and fish eggs. ‘Bakasang’ is well know as typical food of North Sulawesi (Manado) LAB have proteolytic activity that degrade fish proteins into bioactive eptide that could performe as anthyhipertensive compound during fer,emtatopm. This study aimed to identify LAB that produce strong proteolytic abilities. This study revealed that two isolates that were desigh as pediococcus B3.5 and Pediococcus B9.7 based on phenothypic characterization have the strong proteolytic abilities. These strains were further identified by Amplified Ribosomal DNA Restriction Analysis (ARDRA) was carried out with one restriction endonuclesae enzyme (Hae3). Isolates LAB proteolytic from bakasang have a identical character with Pediococcus acidilactici. © 2015, Sphinx Knowledge House. All rights reserved. Source
