Abstract

Spotted barb (Puntius binotatus) is one of tropical fish in Indonesia freshwater, which has high economic value. To maintain the stock in nature, information about the reproduction cycle in the mid raining season is required for conservation so that we can control the catch of spotted barb. This study aimed to examine the effect of raining season on GMS, GSI and GI?s male and female. Observation methods were used as a tool to collect the data. The result of the research showed that a variety of GMS, GSI and GI?s male and female. Quantity of oocyte primer 423; 664; 480; 380; meanwhile that quantity of oosite secondary oocyte 73; 172; 411; 230. Result of water quality measured in the river as temperature 28-30oC, pH 6,8-7 and Dissolved Oxygen (DO) 3-3,4 ppm. The gonad weightgreatly influenced the rate of GMS, GSI, and GI in determining fish reproductionwas interrelated and directly proportional. Increasing of GMSwas affected by the increasing value of GSI and similarly the GI value which is directly proportional with increasing of GSI and GMS. The reproductive cycle of gonadal maturity spotted barb increased during themid rainy season.

Abstract

This study aims to analyze and describe the relationship between altitude, aerial variables (temperature, light intensity, humidity), water qualities (water temperature, pH, BOD, COD, DO, TOM, and water velocity), and vegetation with the diversity of Odonate assemblages. Odonate samplings were conducted at six survey sites based on altitude and vegetation characteristics. Measurement of altitude, aerial variables, water qualities and vegetation characteristics were replicate in the first day and third day. Analysis of correlations of all environmental factors with the odonate diversity was done through structural equation model using Partial Least Squares (PLS), Open source Smart Software and Microsoft Excel. The aerial variables and water qualities affected indirectly on odonate diversity. The aerial variables directly or with interaction to other factor affected the water qualities and vegetation characteristics. The vegetation characteristics directly influenced to odonate diversity. Water flow affected water quality, light intensity affected the aerial, while morning period observation affected the odonate diversity. Predictive relevance (Q2) for a model designed amounted to 99.95%, while the rest of 0.05% are explained by other variables.

Abstract

Hutan mangrove memiliki manfaat dan fungsi ekologi dan ekonomi yang sangat strategisbagi masyarakat. Tujuan dari penelitian ini adalah untuk mengetahui : 1) kondisi hutanmangrove Desa Penunggul dan 2)manfaat langsung dari ekosistem hutan mangrove DesaPenunggul Penelitian ini dilaksanakan pada bulan Dessember 2011- Januari 2012.Pengumpulan data diperoleh dari pengamatan langsung, wawancara dengan masyarakatdan pemerintah desa dan studi pustaka. Berdasarkan hasil penelitian hutan mangroveDesa Penunggul merupakan hutan hasil penanaman dan bukti keberhasilan upayapenyelamatan lingkungan pantai oleh masyarakat. Terdapat dua jenis mangrove yaituRhizophora sp and Avicennia sp. Rhizophora sp mendominasi ekosistem mangrove di DesaPenunggul. Manfaat langsung ekosistem hutan mangrove terdiri dari bibit mangrove,perikanan (kerang, kepiting dan rajungan), dan pendidikan dan pariwisata.
