Abstract

The high changes of Serayu River land use is resulting the high of load particle sedimentation into the body of water. Turbidity will accumulate in the downstream or estuaries which would have an impact on biota, especially plankton as primary productivity and secondary productivity. This research is conducted with a survey method and purposive sampling technique. Estuary Serayu River is divided into 5 stations, starts from the nearest to the sea (1) with 26 ‰ salinity and the furthest stations from the sea (5) with 8 ‰ salinity. Samples of water and plankton are taken at the time of high tide and low tide every month, for 4 months (August, September, October, and November 2016). The obtained data is analyzed by PCA to study the environmental factors towards primary productivity and secondary productivity. Based on the research result environmental factors has relation waters estuary productivity of Serayu river on the highest and lowest tide those are lightness, level TSS and pH.

Abstract

A study was conducted to disclose the habit, food type palatability, and the nest type preference of gelatik jawa (Padda oryzivora). As many as 54 gelatik jawas from Surabaya, Malang, Ngawi, Bekasi, Karawang, Cirebon, Bogor, Semarang, Magelang, Yogyakarta and Prambanan were captured using soft nylon net and then caged for two weeks for adaptation. Each bird was given a ring to make it easier to identify. After the adaptation period, the birds were moved to a wider cage. Every day the habit and mating behaviour as well as the preference of food and nest were observed. The highest  frequency of daily feeding (997.75 ± 72.23) and moving (795.50 ± 138.27); and the lowest  frequency of daily self care (4.126 ± 138.27) and communicate (93.75 ±  7.59) were recorded at 08.00 – 10.00. Food palatability and preference over nest, habit, and biological clock of gelatik jawa could be the basis of ex-situ conservation. The monogamy character of gelatik jawa could also serve as the basis of ex-situ conservation that male and female in one cage must be in equal number.

Abstract

The geographical distribution patterns of parasitic mites determine the types of parasitic mites that should be developed in these endemic geographical regions. Types of parasitic mites and the patterns of geographic distribution of parasitic mites of Aedes sp. in dengue endemic areas in Central Java Province have not been determined yet. The purpose of this research was to determine the parasitic mite and geographical distribution patterns in dengue endemic areas in Central Java Province. All stages of the experiment were conducted by using a survey method with random sampling technique. Sampling area for Semarang City included the counties of Central Semarang and Tembalang, whereas for Banjarnegara including the villages of Krandegan, Kutabanjar, Parakancanggah, and Sokanandi, and the county of Karanganyar City, Karanganyar. Larvae, pupae and adult stages of Aedes mosquitoes. were sampled during the rainy season. Types of parasitic mites were identified using Walter & Proctor (1999), Pesic (2003) and Gerecke (2004) references. The average value and variance were analyzed for the number of each stage to determine the geographic distribution pattern of parasitic mites. The infection ability was determined by the average intensity of parasitic mites and the prevalence value. The results demonstrated that the families of parasitic mites that infect the larvae of Aedes sp. in dengue endemic areas in Central Java Province were Pionidae 1, Histiostomatidae, Hydryphantidae, Hydrachnidae 1, Arrenuridae, Hydrachnidae 2 and Pionidae 2.  Based on the frequency of occurrence, prevalence and the ability to infect, it was concluded that family Histostomatidae is a potential candidate for biocontrol agent of Aedes sp larvae. The distribution pattern of  parasitic mite families in endemic areas of dengue fever in Central Java Province, showed a random distribution pattern.

Abstract

This research aimed to find out the interaction effect between mixed Vesicular Arbuscular Mycorrhiza (VAM) and phosphate fertilizer to the growth of red chili (C. annuum) in acid soil, and to fnd out the best combination of mixed VAM and phosphate fertilizer to the growth of red chili (C. annuum) in acid soil. This research used an experimental method with Completely Randomized Design (CRD) in a factorial pattern with two factors. The first factor was mixed VAM dosages consisted of four levels: 0; 10; 15; 20 g/plant. The second factor was phosphate fertilizer dosages consisted of four levels:  0; 0,2; 0,4; 0,6 g/plant. Each combination treatment had three replication. The parameters were observed in the form of plant height, stem diameter, plant top dry weight, degree of VAM infection, and P content of plant tissue. Data obtained from the observation was analyzed with Analysis of Variance (ANOVA) at an error rate of 5% and 1%, treatment that showed significant or very significant result, then followed with Honestly Significant Difference (HSD) test. The result showed that interaction between mixed Vesicular Arbuscular Mycorrhiza (VAM) and phosphate fertilizer did not increase the plant height, stem diameter, and plant top dry weight, but each factor increased the plant height, stem diameter, and plant top dry weight. VAM dosage inoculation of 20 g/plant without phosphate fertilizer is the most effective combination in increasing the degree of VAM infection.

Abstract

Bulking sludge is a common phenomenon in wastewater treatment plant (WWTP), of which due to excessive growth of filamentous bacteria. Quantity and intensity of organic substrate loading, mode of reactor operation namely aerobic, frequency of anaerobic-aerobic phase determines species and population of filamentous bacteria. Poor organic substrate input and sludge only exposed with aerobic phase appeared to stimulate growth of filamentous bacteria  021 N and 041 N types, Sphaerotilus natans, Microthrix parvicella, Nostocoida limicola, Thiothrix sp. Nocardia group, Flexibacter sp., Beggiota sp. and Haliscomenobacter hydrossis. Increasing of organic loading and sludge exposed with frequent anaerobic-aerobic phase effectively  suppressed excessive growth of Type 021 N, 041 N and Microthrix parvicella. Thus result is better in sludge sedimentation indicated by a decline sludge volume index (SVI).
