Compressive Strength and Workability of Normal Concrete Mixed Beton Mix With and Without Water Reduction

Abstract. The problems of uncontrolled water use in the application of additive use asan additive havebeen significant impact on the strength of concrete and the workability.This paper describes an experimental study of the use of additives, Beton mix, asadditive to normal concrete with certain level. Specimens have been made withoutreduced of water and also by reduced of water. This study focuses on the workabilityand also the compressive strength of specimens. The results of the compressive strengthtest at 28 days, showed that the specimens without reduce of water increased forspecimens with composition of Beton mix 0.15%, but the specimens that use less 0.15%showed decreased the strength of the concrete linearly. In additional, the slump alsoincreased. In contrast to the specimens by reduced of water, a slump showed decreasedwith a maximum reduction limit of 20%, and the strength of concrete showed anincrease of 5%

Pengaruh Faktor Sosial Ekonomi Terhadap Status Kesehatan Masyarakat Di Kecamatan Palu Selatan

The successfulness of public health in South Palu Sub-district contributes to decide the accievement of national develoment. Health population supports not only education program but also the increase of poructivity and household income. Therefore, the main problem of this research was whether the level income of household head who works at formal sector influence the public health status. Similarly, to overcome health problems in certain area is directly related to social and economic factors.In conducting this research, the reseracher applied stratified random sampling technique representing the citezens as responends in South Palu Subdistrict. Therefore, sample consisted of 5 sub-districts, 3 citizen communities, 3 household communities, and 5 household heads. The total number of sample was 126 persons. From the 12 sub-districts, the sample involved 5 subdisrticts: Tatura Utara (35 households), Birobuli Utara (30 households) Tanamodindi (22 households), Birobuli Selatan (18 households), and Tatura Selatan (21 households).After analyzing the data, this research result showed that the income of household head was about 1,500,000.- rupiahs, without social and economic factors that directly influenced toward health status, namely every individual tended to have bad health status. Other factors, such as job area, house environment, social health assurance had significant influence, a=5% with positive sign. It indicated that the head of household with job area was provided well, healthy house environment and health assurance were done better service; therefore, public health status was good for each household. Meanwhile, other factors, they were significant a=15% with negative sign on individual health characteristics, such as respondents age, gendre, long time in completing study, marital status, the head of house hold, and the number of household members did not directly influence bad health status. This results showed that the varibales tends or have opportunity to influence both bad and good health status

The Experimental Study On Laminated Beam By Mahang And Meranti Wood With Variations Connectors

Abstract. Laminated of Mahang and Meranti wood were the efforts to improve theefficiency of hardwood (Meranti) and light wood (Mahang), so that to be used forstructural timber. Variant of connectors were expected to increase laminate beamcapacity compared to solid beams. Samples have been made include properties materialsamples and laminated beam samples with dimension 76 x 5 x 5 cm. Beam sampleswere3 types of connector i.e. glues, nails and bolts. The capacity was obtained by providedone point load at the center of span. In addition to load force, deflection were alsorecorded which then analyzed the flexural capacity, MOR and MOE. The result showedthat at the limit deflection, the glue laminated beam (BL LM) has a higher averagecapacity than the bolt laminated beam (BT BL) and the nail laminated beam (BL PK).In contrast, at the ultimate conditions, BL PK has a higher capacity rather than theothers. At the same time, BL LM has a higher average of MOE of 6818.88 MPa andBL PK has average of MOR 3 times larger than Meranti solid beam (BL ME)

Production Performance and Business Analysis of Clown Loach Chromobotia Macracanthus (Bleeker 1852) in Recirculating Systems with Different Stocking Densities and Water Discharge

Efforts to improve the production performance of clown loach in recirculate aquaculture system can be done by increasing stocking density and water discharge. This study aimed to analyze the effect of increasing stocking density and water discharge on production performance, stress response and water quality in order to obtain the best stocking density and water discharge to obtain maximum profit in a short time. A factorial completely randomized design with two factors, i.e. the stocking density of 1, 2, and 3 fish L-1 and the water discharge of 0,05; 0,10; 0,15 L s-1 was performed. The volume of water used in each aquarium was 48 L and using a ½ inch faucet stop to regulate the water discharge from the inlet pipe. Clown fish fed Tubifex sp. with a feeding frequency of two times a day according to the treatment for 60 days. The result indicates that there was no interaction between the two factors on production performance, payback period, and R/C ratio. Stocking density has a significant effect on specific growth rate, absolute growth rate of individual weight, feeding consumption rate and R/C ratio of clown loach. Stocking density and water discharge had an interaction on the visual color of pectoral and caudal fins of clown loach. Different stocking densities with the combination of water discharge in this study resulted that the water quality were within tolerable range for clown loach so that they did not experience stress, as well as high production and business performance. It is recommended to intensify clown loach with a stocking density of 3 fish L-1 and 0,15 L s-1‑ of water discharge

The Use of Megamolecular Polysaccharide Sacran in Food and Biomedical Applications

Natural polymer is a frequently used polymer in various food applications and pharmaceutical formulations due to its benefits and its biocompatibility compared to synthetic polymers. One of the natural polymer groups (i.e., polysaccharide) does not only function as an additive in pharmaceutical preparations, but also as an active ingredient with pharmacological effects. In addition, several natural polymers offer potential distinct applications in gene delivery and genetic engineering. However, some of these polymers have drawbacks, such as their lack of water retention and elasticity. Sacran, one of the high-molecular-weight natural polysaccharides (megamolecular polysaccharides) derived from Aphanothece sacrum (A. sacrum), has good water retention and elasticity. Historically, sacran has been used as a dietary food. Moreover, sacran can be applied in biomedical fields as an active material, excipient, and genetic engineering material. This article discusses the characteristics, extraction, isolation procedures, and the use of sacran in food and biomedical applications
