Abstract

Oil palm frond  fibers were pulped using acetosolv pulping in laboratory scale batch digester. A central composite desigh was used to investigate the process and to study the effect of its variables on pulp quality and yield. A second order polynomial regression model, using three in dependent process variables, was found to be appropriate for describing  acetosolv pulping oil palm fibers. The overall pulping conditions, which maximize yield while subject to a restriction of kappa number 19.93 were estimated at pulping time of 130 mins, a pulping temperature of 153 oC, AcOH of 85 %  and HCl of 0.25 %

Abstract

The operation of a building construction project should be carried out through aspecific management system. Construction project must also have a definite schedule and implementation plan. The general impact that would occur if the construction is not accordance with the schedule and plan is that the delays in project realization which would increase the cost of implementation. One of the factors causing such delays is due to the reworking activities on one or more items of the construction process. The purpose of this study is to determine the factors that cause rework on the building construction projects in the Department of Highways and Settlements in Aceh Province. The research methodology is descriptive qualitative to descriptive quantitative that explains the processed data based on the calculation of numbers. The instrument of this research was a questionnaire that asked to 55 respondents, consisting of 16 project owners, 23 contractors and 16 supervising consultants. This study was conducted to see the main factors of the rework on building construction projects. The results showed that a major cause of the rework in termof design and documentation was the unclear detail and the changed design; in term of managerial factors is lack of control of the project owner; and materials arrived late and the lack of working experience were major causes of rework in term of resource factors. It is recommended to the Highways Agency and Human Settlements in Aceh Province to tighten control over the project consultants and contractors to pay attention to the managerial problems and procurement of materials in accordance with schedule and work volume

Abstract

The objective of the present case report was to improve knowledge in the management of pregnancy and delivery with Graves’ disease in 32-34 weeks of pregnancy. Primigravida with Graves’ disease was detected at 28 weeks gestational age in patients Mrs. H, 26 years old came with complaints : shortness of breath, leg sweeling, a lump in the neck, the eyes stood out, finger tremors, can not stand the heat, often sweaty, the hearts was tachycardia, increased appetite but weight doesn’t increase and even decreased 8 kg since last five years ago.  Patients had a history of goitre since five years ago, with an irregular treatment. Pregnancy can be maintained after being treated in Departement of Obstetrics and Gynaecology and routinely controlled to assess fetal wellbeing. At 32-34 weeks of gestational age, the pregnancy was terminated by caesarean section, born baby boy, 1930 gr, Apgar Score 8/9. Mother was in good condition after caesarean section. Baby was dead in six days after birth with respiratory distress syndrome DD/ pneumonia aspiration. Hyperthyroidism which not handled will have a serious complications, but if properly handled and monitored, maybe the results of maternal and fetal outcomes expected good. Antepartum fetal assessment include fetal heart rate, the amount of amniotic fluid can be a parameter for pregnancy termination planning. The results of poor outcomes are things that must be observed that Graves’ disease in pregnancy have a risk of neonatal mortality

Abstract

Heavy metals have widespread industrial uses and have been found in increasing quantities as contaminants in all components of the biosphere. Water and sediment of rivers near industrial areas such as the Juru River in Penang and Langat River in Selangor are polluted with heavy metals. Thus, rapid and fast methods to detect the presence of heavy metals in the environment are necessary. Existing instrumental methods such as atomic absorption and emission spectrometry are very sensitive but the sole use of these instruments for heavy metal detection is extremely expensive, needs a skillful person to operate and is not amenable to near-real-time analysis. The best scenario for routine biomonitoring of heavy metals is the marriage between instrument- and bioassays. Currently, the USEPA has recognized whole cell-based bioassays such as as PolytoxTM and Microtox® for the detection of heavy metals. Unfortunately these cell-based assays cannot be used as real-time or near real-time assays in the field as they require bulky incubators. Near-real-time monitoring of heavy metals giving results in less than one hour is very useful in environmental CSI (Criminal Scene Investigation) or ECSI where temporal and spatial concentrations of heavy metals in running waters are a challenge to environmentalists to pinpoint heavy metals POS (point of source) for legal purposes. Enzyme-based inhibitive assays are simple, rapid and fast and could be developed for near real-time assays. We have developed an inhibitive assay system –Xenoassay® based on proteases for the assay of heavy metals. The system could detect the heavy metals mercury, cadmium, lead, copper, zinc and silver at the sub parts per million level. Field trial near-real-time assay capability shows promising results.

Abstract

The objective of the present study was to investigate useful of Wedelia biflora leaves extracts as  anti allergic caused by dermatitis allergic in mice. A total of 24 males Wistar mices were utilized as experimental animal in this study. The experimental animals were divided into 4 groups, and each group has 4 mices. The first group was a control which was injected with aquades (negative control), while three other groups (group 2 to group 4) were fed with   Wedelia biflora extracts orally at doses of 20 g, 40 g and 60 g per kg body weight, respectively, and the fifth group was a positive control which was injected with 10% ovalbumin, and the last group was given antihistamin drug (Loratadine) as compared control. All of experimental animals were injected with ovalbumin on day 1, 7, and 21, except for  negative control  which were injected with distillated water. The ectracts of Wedelia biflora were fed for 21 days. The inflammation areas were measured using a digital caliper and analysis one-way Anova. The results showed that the treatment of Wedelia biflora were resulted in reducing inflammation size significantly (p0.05) where the dose of 60 g/kg body weight was given the best result compared to other doses due to this value equivalent to antihistamine drug loratadine. We concluded that Wedelia biflora leaves extracts had the anti allergic effect.

Abstract

The objectives of this Research would like to know the effect of probiotic starbio in dodol multinutrition (DM) on the performance of male bali cattle. This research was done in four treatment and periods usind 4 x 4 latinsquared design (LSD). All animals were fed native grass ad libitum as a basal diet. The treatment were P0 (DM without the addition of probiotic starbio), P1 (DM with the addition of 2% probiotic starbio), P2 (DM with the additionof 4% probiotic starbio), P3 (DM with the addition of 6% probiotic starbo), with average initial body weight 157,25 + 10,7kg. The result of this research indicated that the averages of feed consumption in dry matter (kg/head/day)sach as: (3,50; 3,69; 3,83 and 3,88 respectively); average daily gain (ADG) (kg/head/day) such as: (0,52; 0,56; 0,60 and 0,63, respectively); Average of feed convertion ration such as: (6,711; 6,640; 6,369; and 6,198,respectively) and IOFC (Rp) such as : (182,132; 204,071; 234,798 and 251,004, respectively). The addition of probiotic starbio in the DM has a very significantly different (P0,01) on feed intake and body weight gain of male bali cattle, however significant different (P0,05) with feed conversion ration male bali cattle. It could be concluded that probiotic starbio could be used to increase feed consumption, body weight gain, feed efficiency in feed and IOFC.

Abstract

The area of coverage of waste management services in some areas sometimes only focus on specific areas such as the capital province, district or city. Some areas of the region (district) still do not get special attention for waste management facilities services from local City Sanitation Department. In this study we raised two villages located on the banks of the Kampar River and examined the management of non-organic domestic waste in this area. We choose Pulau Birandang Village and Alai Village because of the habit this people to throw garbage like non-organic waste (such as paper, plastics, etc) to the Kampar river. This act is very dangerous for the sustainability of water security and can cause silting rivers. The aims of this research to analyze the influence of commercial approach as a solution to solve waste problem in both villages. Commercial approach is the method applied by giving incentives to people who are sort the non-organic waste according to its kind. Data for this study were collected from observation using 80 questionnaires to 80 respondents from both villages, the Pulau Birandang village and Alai village. Results of the analysis is also reinforced by opinión from the leaders of them (people) who are likely to reflect the wishes of the people too. The results from this study is the commercial approach (take and give system) which applied in this villages could increase people's enthusiasm in managing domestic waste by sorting waste before it is collected.
