Abstract

Penelitian tentang distribusi dan komposisi sampah laut pesisir di Kecamatan Kuala Pesisir Kabupaten Nagan Raya yang di lakukan pada bulan Juli s/d Agustus tahun 2017 bertujuan untuk mengetahui distribusi dan komposisi sampah laut di pesisir yang terdapat di Kabupaten Nagan Raya. Penelitian ini menggunakandua titik lokasi penelitian antara lain lokasi pertama pantai peunaga permai tempat wisata dan lokasi kedua pantai seunagan tempat pemancingan. Metode yang digunakan adalah deskriptif kuantitatif dan kualitatif yaitu metode pengamatan secara langsung untuk mengidentifikasi semua jenis sampah pesisir yang terdapat di ketiga stasiun pada dua titik lokasi penelitian. Hasil penelitian pada bulan Juli 2017 selama 28 hari jumlah sampah yang terdapat dipesisir laut pada dua lokasi penelitian sebanyak 6 jenis sampah antara lain sampah plastik, logam, kaca, karet, kayu olahan dan sampah kain-kain. Komposisi jenis sampah yang tertinggi terdapat pada lokasi pertama yaitu kawasan tempat wisata dengan jumlah total 15,931 dan jumlah persentase (75 %) sedangkan jumlah yang paling terkecil terdapat pada lokasi ke 2 yaitu pada kawasan pemancingan dengan jumlah total sampah 5.287 dan persentase (25 %). Jadi dampak pencemaran sampah tertinggi terdapat pada kawasan peunaga permai dengan jumlah rata-rata sampah 569 dan kawasan pemancingan dengan jumlah rata-rata sampah 192. Jenis sampah yang paling banyak pencemarannya padadua lokasi penelitian yaitu jenis sampah plastik sedangkan sampah kaca paling sedikit pencemarannya.

Abstract

ABSTRACTHybridization program was started in PKBT IPB Bogor in 2003, entangles of 12 parental cultivars, consisting of five type Smooth Cayenne cultivars and seven type Queen cultivars. The cross yielded 195 genotypes with various different character combinations. The result of cluster analysis based on morphological characters showed that there were 33 groups of hybrid at the degree of genetic similarity of 50%. The result of principal component analysis indicated that, between yield component characters and result most importantly, were fruit weight, fruit diameter and fruit length which were main supporting character of variance in hybrid result of the crosses. Descriptive results of fruit yield and quality characters showed three to five classes with the highest number of individuals around the mean value for each character. Fruit weight, crown weight, fruit length, fruit diameter, flesh thickness, core diameter, total soluble solid (TSS), total acid, vitamin C, pH, plant height, and peduncle length, were characters controlled by nuclear genes.Key words : hybridization, variability, Smooth Cayenne, Queen, genotype

Abstract

Humpback grouper requires suitable water quality for life whether physics, biology, or chemistry aspect. The purpose of this study is to determine the physical indicators, chemical parameters, and the appropriateness level of waters for potentially conducting fish farming activities of Humpback grouper by employing floating cage in waters of Bay Rigaih, Aceh Jaya District. Researcher conducted the study from August to September 2016 and employed survey approach. Determining the location of the sampling point is by using purposive sampling. The sampling coordinates recorded with the Global Positioning System (GPS). Based on data from research sampling, The results show mean value for each physical parameters such as: a). The depth is 9.5 m; b). the brightness is 3.7 m; c). water temperature is27,66 oc; d). The current speed is 20.25 cm/sec. Samples of some stations show mean values of chemical parameters such as: a).

Abstract

This technology is known as bioreeftek technology. Bioreeftek? is ?a ?technology ?developed ?by ?the ?KKP ?Research ?and ?Observation Center (Ministry of Maritime Affairs and Fisheries) in the past few years. This research will examine the number of coral recruitment in coconut shells as natural artificial substrates in 3-5 and 8-10m depths. The coconut shells module composed of 9 pieces consisting of 3 modules installed 1 coconut shell each pole, 3 modules installed 2 coconut shells each pole, and 3 coconut shells attached 3 coconut shells each pole. Retrieval of coral sapling data for about ?4 months. Data is taken directly (in situ) by looking the number of juvenils attached to each substrate. The results obtained show the attachment of two genera of juvenil namely acropora and pocillopora at each depth. The highest number of attachments is found in modules that have 3 shells in each module. The best depth for juvenil attachment is at a depth of 3-5m.

Abstract

West Sumbawa regency located in West Nusa Tenggara Province is potential areas for seaweed cultivation like Euchema cottonii. Currently, the center of seaweed farming activities located in the Gulf of Kertasari and Poto Tano. Market demand for commodities of E. cottonii tends to be increase, and therefore new areas of cultivation are required to be developed, through a study of physics, chemistry and biology of marine aspect is needed to assess the farming area suitability.The methodto determine the suitabilityarea is using GIS (Geographical Information System) analysis. The resultshowed thatPoto Tano District has 805 ha of suitable area for cultivation. While, Taliwang and Jereweh District consist of the area about 70 ha and 86 ha. Total land suitable for the cultivation of seaweed approximately 961 ha.

Abstract

Barnacle (Amphibalanus spp.) density and distribution implemented in September-November 2013 in the port of Dumai, Riau, which aims to explore the causes of inequality in the spatial distribution of density Barnacles (Amphibalanus spp). in different media attachment were influenced by marine environmental conditions in the port of Dumai. Barnacle density observation method in this study is the stratified random sampling method using wood, fiber and iron as a media attachment. The results showed the existence of inequality Barnacle density (Amphibalanus spp). on the media attachment with different types and colors. The highest average Barnacle density was found in colorless timber, which ranges between 265-506 ind/m2. While the lowest average Barnacle density was found in white fiber and it ranged between 25-68 ind/m2.

Abstract

Most of coastal waters of West Sumbawa are wave-exposed areas. As part of Alas Strait this region is located between Lombok and Sumbawa Island. On the land and coastal areas, mineral mining (i.e. gold) activities are operated massively by large private company (i.e. PT. Newmont Nusa Tenggara) and traditional mining by local communities. These activities (especially for traditional mining) are expected to increase the content of heavy metals in the marine and coastal waters surrounding. A residual of mining processing will produce heavy metals disposal. In this study, the distributions of heavy metals (i.e. Hg, Cr6+, Cu, As, Ni, Zn, Pb, and Cd) were measured in the water column and bed sediments of coastal waters of West Sumbawa. This study was conducted during dry season in July 2011. The results show the heavy metal concentrations in water column were mainly within the permissible limits (based on Keputusan Menteri Lingkungan Hidup No. 51, 2004). Except for Cu, the concentration was highest found on most of the stations. The heavy metal contents in bed sediment were low, but varied among sampling points. Furthermore, Cu content in bed sediment also found remarkably high (101,7 mg/Kg) with additionally Zn content was closed (10,6?105,5 mg/Kg) within the permissible limits (based on criteria by Australian and New Zealand Environment and Conservation Council ? ANZECC, 2000).
