Abstract

Study was done for the use of the third-generation of downflow hanging sponge (G3-DHS) bioreactor for secondary treatment of septic tank desludging wastewater. The main objective of this study was to evaluate the prospective system of G3-DHS bioreactor to be applied in Indonesia. During experiment, the G3-DHS bioreactor kept a relatively high dissolved oxygen concentration under natural aeration. At a relatively short hydraulic retention (HRT) of 3 h, the G3-DHS bioreactor could remove up to 21% (SD = 15%) of total COD, 21% (SD = 7%) of filtered-COD, 58% (SD = 24%) of unfiltered-BOD, and 33% (SD = 24%) of ammonium removal. The final effluent had an unfiltered-BOD of only 46 mg/L (SD = 20 mg/L) that it was below the Indonesian standard (unfiltered-BOD = 100 mg/L) for thresholds of domestic wastewater treatment plants effluent.

Abstract

The incidence of uterine rupture was devastating to the outcome of mother and the baby. This serial cases were to evaluate and analyze many factors which contributed to uterine rupture in Zainoel Abidin Hospital, Banda Aceh. Six serial cases of uterine rupture in almost one year (January 2011-Agustus 2011) were analyzed. There were six cases of uterine rupture. All cases happened in patients with previous caesarean sections. There were two cases in patients with classical previous caesarean section incision. One case happened in patient with previous caesarean section eleven months ago or short delivery interval. Two cases happened in prolonged of the second phase of labor more than 4 hours. One cases happened in second phase of labor less than one hour. Among six cases, there was one perinatal death in uterine rupture due to prolonged second phase of labor more than 5 hours. Previous classical uterine incision, second phase of labor, and inter-delivery time in previous Caesarean Section were contributing factors to the incidence of uterine rupture that can be predicted. So many ways can be used to prevent them

Abstract

In many crude oil spill sites, dispersants are widely applied during clean-up operations without adequate consideration of their environmental effects. This is despite the fact that the water accommodated fractions of these mixtures contain toxic components. This study investigated the uptake of polycyclic aromatic hydrocarbons (PAHs) from the water accommodated fractions (WAF) of a mixture of a dispersant, Goldcrew and Bonny Light crude oil using a tilapian fish, Oreochromis niloticus. The aim was to determine the critical body residue (CBR) of the PAHs in the fish exposed to the dispersed, dispersant and crude oil in water (DCOWAF-PAH) and undispersed, crude oil in water only (COWAF-PAH) regimes of the mixtures in the WAF. The control experiment had water only. The concentrations for both regimes of exposure were at sub-lethal levels of 0.2, 0.4, 0.8 and 1.6ml/L for fifty days using renewal static bioassay. The types and total concentrations of PAHs were analyzed for in the crude oil, fish feed administered, preexposed fish sample, dispersant and test water before exposure. The sixteen known carcinogenic PAHs were found in the crude oil (1916.4ppm), eleven in the fish feed (0.57ppm), three in the pre-exposed fish(0.007ppm), and none in the dispersant and test medium (water). The concentration of the PAHs in the fish from the DCOWAF-PAH ranged from 3.6128-7.9744ppm while that of the COWAF-PAH ranged from 3.4114-3.9693ppm. The concentrations of individual PAHs recovered in the fish showed that napthalene had the highest CRB level of 6.7780ppm and 3.2610ppm, anthracene was 0.6590ppm and not detected (N.D) while acenaphthene had the lowest CBR of 0.00001ppm and below the limit of quantification (LOQ) forthe DCOWAF-PAH and COWAF-PAH exposure phases respectively. The results showed the order of the CBR level as NAPFLBaFBaPBaAFLUPHE in the COWAF-PAH irrespective of exposure concentration, while for the DCOWAF-PAH, it was NAPFLUBaFBaPB(ghi)PBaABkFPHE. The results demonstrated that the presence of the dispersant, Goldcrew increased the critical body residue of the PAHs irrespective of the concentration in the fish samples. This was especially so for the low molecular weight PAHs (200). Thus, the application of dispersants for crude oil spills need to be done with utmost care particularly in fishing grounds

Abstract

Among three genera of open-air processional column termites in Sumatra, Longipeditermes is the most commonly observed. Their workers make food balls at the foraging sites and carry them back to the nest. This genus has a black color, long legs and antennae. Antenna is much paler than head capsule in coloration, with the basal segments (first and second) are generally darker than subsequent ones; antenna is long with fourteen segments; third segment is twice as long as fourth or more. Their distribution in Sumatra is mentioned briefly

Abstract

This study aims to determine solution of Boussinesq equation which is approximated by using asymptotic expansion method. Nonlinearity of Boussinesq equation causes the solution is not easily determined, so the solution is approached through its linearity. This method is in the form of power series expansion up to third-order, where each term of the series is linear. Furthermore, the finding solution is compared with the solution that was found by Mohyud in previous study. The result of this comparison showed that there were similarities of the two solutions. However, differences occur in phase as modeled in the solution of each method

Abstract

Nurse scheduling problem is one of the most difficult scheduling problems to solve since its solution space is large and it expects to comply many constraints. There is no standard model or a method of solution for nurse scheduling. The main objective of this study is to search for a scientific method to prepare a monthly working schedule for a group of nursing officers employed in a hospital. We propose an optimization method to prepare an optimal schedule. Initially, we develop an optimization model by formulating the objective and the constraints of the problem. The optimization model that we are interestedin is a 0-1 Integer Linear Programming problem. We apply the Branch-and-Bound technique to solve the problem using the optimization software package LINGO. Finally, the solution to the optimization problem is formulated to a regular nurse schedule. The methodology is illustrated by preparing a monthly schedule for a private hospital in Sri Lanka.

Abstract

This study aimed to extract the active antioxidant compounds from curry leaves (Murayya koeniigi) and salam leaves (Eugenia polyantha) using three types of solvent; water, ethanol (50%) and hexane, and determine the total polyphenols contents, activity of free radicals scavenging using DPPH (1,1-diphenyl-2-picrylhydrazyl) and ferric reducing power of the extract of those materials. The result showed that curry leaves extracted using water contain a higher amount of polyphenols than other solvent extracts, while for the salam leaves, ethanol (50%) extracts give a higher polyphenol content than others. Total polyphenols extracts had a positive correlation with antioxidant activity in both DPPH radical scavenging and ferric reducing power. Extracts that contain a high amount of polyphenols also exhibit high antioxidant activity. The result indicated that the polarity level of the solvent will determine extraction result and its antioxidant activity

Abstract

The recent increase in drug-resistance bacteria has become a very serious threat to the treatment of infectious diseases. Over recent decades, a growing numbers of literatures have validated the application of bacteriophages for therapy against antibiotic-resistance bacteria. With rapid dissemination of these resistant bacteria pathogens, the interest in alternative remedies to antibiotics using bacteriophages therapy is gaining new ground. Based on the recent studies of bacteriophage applications against bacterial infections in countries where this alternative therapy has been approved, many scientists and companies believed that phages have the ability to treat and prevent diseases caused by bacteria. Malaysia, being well known as one of the mega diverse countries could promise the potential new phages that could be applied in phage therapy. The overall objectives of this research including isolation and purification of potentially new phages from environments, characterization of the isolated phages based on morphological study, physicochemical attributes, genomic and proteomic analysis. Lastly, the isolated phages would be developed into phage therapy against bacterial infection through in vitro and in vivo test. Preliminary results presented here, show a total of four phages were successfully isolated from human waste. Two of the phages were successfully isolated infecting Proteus mirabilis that caused urinary tract infection in human whereas another two phages infecting Escherichia coli 0157:H7 (caused food-borne diseases) and Escherichia coli ATCC 13706, respectively.

Abstract

Water availability is a major factor affecting rice production especially in upland.  The Production of upland rice is low because of the low of  water availability in upland.  Roots play an important role in upland rice adaptation to drought conditions. This study aimed to identify the characteristic of upland rice variety root development under  soil moisture gradients. This study use  randomized  factorial design consisting of 2 factors and 3 replicate.  Factor I : 12 upland rice variety, ie: Silumut, Batutegi, Limboto, Situpatenggang, Situbagendit, Towuti, Cirata,  Danau Gaung, Gajah Mungkur, Inpago 4, Inpago 5, Inpago 6. Factor II :  gradien of soil moisture level, ie: 20 %, 40 %, 60 %, 80 % field capacity. The Result of research indicate all the upland rice variety were classified tolerance based on relative value of root leght. The highest root lenght and the heaviest root dry matter were generally from combination uplandrice varieties with 60 80 % field capacity except Inpago 4 and Situbagendit showed  the highest root lenght at 20 % field capacity and combination The heaviest root dry matter at 40 %were Inpago 4 and Jatiluhur generally from characteristic of  root gro field capacity
