Abstract

Diatoms are a micro-alga dominates in the aquatic ecosystem. Their silicious cell wall able to preserve death diatoms in the sediment for long periods of time, therefore, diatoms have an important role in the paleolimnological analysis. Diatoms assemblages in the sediment layer express the water quality whenever the diatom lives. This article provides information how to apply diatom on the paleo-limnological analysis, supporting with the case study in the Lac Saint-Augustine Quebec-City Canada and Rawa Pening Lake Indonesia. Modern diatom and the water quality from spatial and temporal range are used as a calibration set. The diatoms of below layers, then, Weighted Averaging (WA) with the calibration set to reconstruct the water quality in the past. Previously, both in Canada and Indonesia, those lakes were oligotrophic and sharply change into eutrophic condition since a lot of human activities developed around the lakes (anthropogenic factors). Naturally, the maturity of lake can not avoid and the succession had been fast by eutrophication. Paleolimnological approach provides baseline data in the past to develop the appropriate lake management.

Abstract

Rafflesia patma is an endemic plant of Pangandaran, West Java which is protected because of its rare status. The purpose of this research is to study the population structure, distribution patterns, and the effect of the physical environment of abundance R. patma in Pananjung Pangandaran Nature Reserve, West Java. The method used in this research was a survey method with a purposive sampling technique. Sampling was conducted using quadrat plots. The population pattern distribution was defined by a standardized Morisita index, and the analysis of abiotic environmental factors was determined by Principal Component Analysis (PCA) using PAST3. The results showed that there were 114 R. patma individuals scattered in several research areas in Pananjung Pangandaran Nature Reserve, they were Gua Parat (3 individuals), Cilegon (13 individuals), Pasir Putih (12 individuals), Badeto (48 individuals), and Curug Leutik (38 individuals). The distribution pattern of R. patma in Pananjung Pangandaran Nature Reserve was clustered with the Morisita index value (Id) > 1. Based on the PCA analysis, results that support the classification of the cluster analysis were obtained. Based on four abiotic environmental conditions analyzed, the most dominant character in influencing the distribution patterns and population structure of R. patma is light intensity.

Abstract

The coastal zone of Losari Beach is located in a strategic position and rich in potential coastal resources, but the high density of human activities has decreased the quality of the surrounding waters.This study aimed to examine water quality based on meiofauna abundance and pollution index in the coastal zone of Losari Beach, Makassar. It employed a quantitative descriptive approach with purposive sampling method. The identified total meiofauna abundance was117,176 individuals/m2consisting of 138 species from 13 phyla. Ostracoda, olygochaeta, sarcomastigophora, ciliophora, and polychaetawere phyla with the highest abundance because of their high adaptability to polluted aquatic conditions. Meanwhile, tardigrada and aelosomatidaewere found in very low abundance because both phyla only thrive in pollution-free environments and have a pattern of high migration flow from one habitat to another. As for aelosomatidae, the habitat of its speciesis limitedto brackish or saline waters. A good-quality aquatic environment is a habitat for all benthic organisms and enables their even distribution. It explains the discovery of true and temporary meiofauna with uniform or even compositions in the bottom of the waters. The waters in the coastal zone of Losari Beach are heavily polluted. The stationslocated around the traditional Paotere harbor, hotels, restaurants, Losari Beach Platforms, the waste disposal outlets of Stella Maris Hospital, Fort Rotterdam canals, and Jeneberang River mouthhad very high pollution index. Some of these stations had low meiofauna abundance levels, and the poor water quality in their surroundings was caused by anthropogenic activity. Even though the area around TanjungMerdeka Beach had relatively low pollution index, it was categorized as severely contaminated because the index score was >10.

Abstract

Culex tritaeniorhynchus and Culex vishnui are medically essential mosquitoes that transmit the Japanese encephalitis (JE) virus. There is less information about the recording data and research due to genetic character differences among them. The objective of this study was to examine the genetic variation of Cx. tritaeniorhynchus and Cx. vishnui in 3 sites of Central Java using polymerase chain reaction randomly amplified polymorphic DNA (PCR-RAPD). The study was done in January to November 2017 in Pekalongan city, Pekalongan regency, and Semarang regency. Adult female mosquitoes collected by human bite method. DNA of ten Cx. tritaeniorhynchus samples and fifteen samples of Cx. vishnui purified using DNA extraction kit. Furthermore, PCR amplification was conducted with 5 RAPD primers (OPA 11, 12, 15, 16, and 20) and would run into 2% gel electrophoresis for 45 minutes. Cluster analysis was using MVSPTM software (version 3.1). The results showed 213 genetic characters of Cx. vishnui, while 142 characters shown by Cx. tritaeniorhynchus. The dendrograms showed three distinct groups of Cx. vishnui from 2 sites of Pekalongan and one site of Semarang, while Cx. tritaeniorhynchus showed two distinct groups, which were 1 group from Pekalongan and 1 group from Semarang. Low genetic similarity (<10%) shown Cx. vishnui from Pekalongan city and Pekalongan district, and there was no genetic similarity in Cx. tritaeniorhynchus from Pekalongan and Semarang. It concluded that the polymorphism of Cx. tritaeniorhynchus and Cx. vishnui reached 100%. ANALISIS FILOGENETIK CULEX TRITAENIORHYNCHUS DAN CULEX VISHNUI VEKTOR VIRUS JAPANESE ENCEPHALITISNyamuk Culex tritaeniorhynchus dan Culex vishnui memiliki peran penting di bidang medis terutama dalam penularan virus Japanese  encephalitis (JE). Sampai saat ini data dan riset tentang karakter genetik vektor JE masih sangat terbatas. Penelitian ini bertujuan menjelaskan variasi genetik Cx. tritaeniorhynchus dan Cx. vishnui di 3 lokasi di Jawa Tengah berdasar polymerase chain reaction randomly amplified polymorphic DNA (PCR-RAPD). Studi ini dilakukan dari bulan Januari sampai November 2017 di Kota Pekalongan, Kabupaten Pekalongan, dan Kabupaten Semarang. Metode human bite digunakan untuk koleksi nyamuk. Ekstraksi DNA nyamuk dilakukan pada 10 ekor Cx. tritaeniorhynchus dan 15 ekor Cx. vishnui menggunakan kit ekstraksi DNA. Selanjutnya, diamplifikasi dengan 5 macam primer RAPD (OPA 11, 12, 15, 16, dan 20), serta dielektroforesis pada 2% agar selama 45 menit. Analisis klaster dilakukan menggunakan program MVSPTM (versi 3.1). Ditemukan 213 dan 142 karakter genetik masing-masing pada Cx. vishnui dan Cx. tritaeniorhynchus. Analisis dendogram menunjukkan 3 grup yang berbeda untuk Cx. vishnui, sedangkan untuk Cx. tritaeniorhynchus terdapat 2 grup yang berbeda, yaitu 1 grup dari Pekalongan dan 1 grup dari Semarang. Similaritas genetik yang rendah (<10%) ditunjukkan Cx. vishnui dari Kota Pekalongan dan Kabupaten Pekalongan, bahkan tidak ada persamaan genetik pada Cx. tritaeniorhynchus dari Pekalongan dengan Semarang. Disimpulkan bahwa polimorfisme Cx. tritaeniorhynchus dan Cx. vishnui mencapai 100%.

Abstract

The aim of this study is to analyze the spawning pattern and fecundity of the javaen barb (Puntius orphoides). Samples were collected during one year, from June 2009 until May 2010. Fish caught by gillnet with long-stemmed and fish trap in Klawing River, Purbalingga, Central Java. Analysis was done to estimate gonado somatic indices, gonad maturity, fecundity, and frequency of oocyte diameter distribution. The javaen barb caught were 431 fishes, consisted of 200 male and 231 female, with varied total length in the range of 95-294 mm, and weight 12.0-276.4 grams. First maturity gonad of male fish was 109 mm TL, while female fish was 118 mm TL. According to analysis of gonado somatic indices and gonad maturity stages, fish was estimated to spawn in the long time with its peak in September-October. Fecundity was 7,379-39,794 oocytes, and oocyte diameter was 25-900 ^m. Based on the development of oocyte stages, the javaen barb have an asynchronous spawning pattern, and based on the distribution of oocyte diameter suggested that this species could be grouped as partial spawner. AbstrakPenelitian ini bertujuan menganalisis beberapa aspek pemijahan dan fekunditas ikan brek (Puntius orphoides).
