Abstract

Batu-Malang Government area is one of central production of citrus ”Keprok 55” in East Java. In dry season, citrus produce low production level, because there is unsufficient water inside the soil. Based on this facts, some efforts is needed in order to increase the citrus production especially to face the dry season, through sprinkle irrigation system to increase citrus production. Sprinkle irrigation system has been installed on citrus plantation in Selorejo Village, Batu.Citrus is one of the horticultural commodities which have priority to be developed. One type of citrus that favored consumers are mandarin (tangerine). During the period 2005-2009 tangerine imports reached 504,063 tonnes, or about 100,813 tonnes per year with a value of US $ 80,569,300. Management of commodity Citrus 55 in Selorejo village, subdistrict Dau, Malang not get maximum benefit due to the limitations of the use of technological innovation as well as the lack of capital. The experiment calculated HPP, BEP, NPV, R/C ratio, IRR and PP. This study was to compare the effect of management changes Citrus 55 between conventional and sprinkler irrigation. The financial viability of commodity management Citrus 55 in Selorejo Village declared eligible to run either conventionally or with sprinkler irrigation. Age commodity management business is ten years. Conventional management NVP value is IDR 1,234,468,408 and the value of NVP management with the use of sprinkler irrigation is IDR 5,200,599,957.

Abstract

Objective: To determine the effect of Bryophyllum pinnatum treatment in modulating immune response and the pregnancy outcomes of pregnant pristane-induced lupus mice model.Methods: Sixteen Balb/c mice were intraperitoneally injected with single 0.5 cc pristane to induce lupus manifestations. After 12 weeks of injection, mice were mated and considered as gestational day 0 (GD0). Mice were divided into 4 groups based on the dosages of Bryophyllum pinnatum: control (no treatment), B1 (10.5 mg/kg), B2 (21 mg/kg), and B3 (42 mg/kg). The treatment was given orally every day started from GD9 until 9 days. At the end of the study, blood pressure and fetal size were measured. Serum anti-dsDNA and urine albumin levels were measured by ELISA. Spleen T helper (Th) and mature B cells percentages were measured by flow cytometry.Results: Administration of Bryophyllum pinnatum reduced the percentages of Th1 (p=0.006), Th2 (p=0.005), Th17 (p=0.000), and mature B cells (p=0.007) in dose-dependent manner. B1 and B2 had significantly lower of systolic blood pressure compared to control (p=0.026 and p=0.022 respectively). Significantly lower of anti-dsDNA levels were found in B1 group compared to control (p=0.014). However, no significantly different of urine albumin levels were found between groups. Bryophyllum pinnatum also significantly increased the fetus body weight in dose-dependent manner (p=0.000).Conclusion: Treatment of Bryophyllum pinnatum could improve the pregnancy outcome and modulate the immune response in pregnant pristane-induced lupus mice. Therefore, Bryophyllum pinnatum is a potential herb which can be developed as an immunosuppressive agent in the future.

Abstract

The objectives of this study were to evaluate the prebiotic activity based on the change in cell biomass of the probiotic strain after 24-h growth in the presence of Laminaran from Sargassum crassifolium with the methods of laminaran acid extract (LAE) and laminaran modified extract (LME), inulin, or glucose-relative against the change in cell biomass of Escherichia coli FNCC 0091 grown under the same condition. Prebiotic activity was calculated for L. plantarum FNCC 0051 and Bifidobacterium longum FNCC 1081. The results showed that the increasing cell number of L. plantarum was higher in both substrates LAE and LME (0,58 and 2,03log cycle), whereas that of B. longum was lower. The higher prebiotic activity score obtained for L. plantarum and B. longum grown on LME were positive (0,26 and 0,96 log cycle), whereas the lowest score was for L. plantarum and B. longum grown on LAE, which were negative (-0,35 and -0,31 log cycle), but the higher prebiotic activity score was obtained for inulin (4,08 and 4,78 log cycle). It could be concluded that Laminaran Modified Extract (LME) has potential as prebiotic source, but its potential was lower than inulin.

Abstract

Balinese Sardinella (Sardinella lemuru) is the main commodity in Indonesia. Despite, more research show that lemuru got the overfishing condition. In East Java region, likely Bali Strait, Southern-East Java water, and Madura Strait are the region which the most production of lemuru catch. So it needs identification stock of Sardinella lemuru on the third fisheries management east java sub-region, as it to be used as a reference to managing the sustainability of the catch sardinella lemuru for the future. Research carried out in January to May 2016 with the methods is the sample of random sampling on three different locations water representing Madura Strait, Bali Strait, and southern-East Java water. The each sample implemented were in four times during a period of months old different. Every the sample researchers get as 50-200 tail. Sardinella lemuru in accordance with the season fish. The sample which has been obtained taken to the laboratory of Marine Science University of Brawijaya to data take. The analysis used in this research was Truss morphometric and Factor analysis of the condition allometric. Based on the results of the analysis in the Madura Strait, Bali Strait, and Southern-East Java water are having a distinction of morphometric character amount 44 % with the character being very affected is PAL_FL, DFB_HL , PVL_FL, UPCL_FL, OD_HL, and PPL_FL. Around 64 % of the whole morphometric character that is 14 characters. Next, if it is seen from Allometric condition in the third these waters having b value different from each aquatic and after B-test that lemuru in the three the waters might otherwise dissimilar stock so management of Sardinella lemuru in the three waters should have been undertaken in separated.

Abstract

Sardinella fish (Sardinella lemuru) is a species of important pelagic fish from the family of Clupeidae found in Bali Strait. The dynamic condition of Bali Strait makes it fertile which is identical with plankton blooming. The objective of this research was to understand the potential of saxitoxin in sardinella fish because of dinoflagellates consumption in Bali Strait. The research was conducted in Southeast Monsoon (June - August 2015) and Northwest Monsoon (December 2015 – February 2016). The method used was in situ plankton sampling, counting and ELISA test to determine the level of saxitoxin in the fish. Hydro-oceanographic parameters measured were temperatures, salinity, DO (dissolved oxygen), pH level, phosphate level, nitrate level and transparency. They showed average optimum value for phytoplankton growth especially during Southeast Monsoon which its temperature lower and the nutrients (phosphate nitrate) higher than the Northwest Monsoon. This condition caused high richness of phytoplankton in the water and followed with dinoflagellates richness so they accumulated in sardinella fish. It was supported by the analysis of the fish gastric which showed positive correlation between dinoflagellates richness in the water and the fish gastric. ELISA test also showed that saxitoxin level of fish caught in Southeast Monsoon was higher than the one caught in Northwest Monsoon even though the level of saxitoxin was still in the safe range (less than 80 μg STXeq. per 100 g) but the danger of saxitoxin accumulation should be watched out for.
