Abstract

AbstractBarnacles are symbiont and harm to the crabs when they are in large numbers. They will affect the respiration, normal activity and growth of the crabs. The prevalence, mean intensity and identification of pedunculate barnacle, Octolasmis spp. on blue swimming crab, Portunus pelagicus from the coastal area of Kuala Terengganu were studied. The site specificity of the different species of Octolasmis attached was examined. The crabs were measured and weight. The crabs were euthanized by put in ice until no movement. The Octolasmis were observed from the surfaces and gills or brachial chamber. The Octolasmis were observed from each gill. The prevalence and mean intensity was calculated. The Octolasmis were preserved in 70% alcohol and mounting using glycerine jelly to make the permanent slide. A total of all 13 crabs were infested by four species of Octolasmis which is 218 Octolasmis angulata, 191 Octolasmis warwickii, 16 Octolasmis tridens and 218 Octolasmis lowei. Octolasmis angulate showed the highest prevalence (84.62%) and lowest prevalence was O. lowei (23.08%) and O. warwickii (23.08%). The barnacles were attached to the gill, carapace, abdomen and also walking legs. Barnacle occurred most frequently on the gill part by having 371 (57.70%) barnacles compared to other areas, 272 (42.30%) barnacles. The distributions of barnacle in this study suggest distal areas are more susceptible in infestation by Octolasmis spp. However, they did not show site specificity on the gill areas because it depends on the water current.AbstrakBarnacle (teritip) adalah simbion yang dalam jumlah besar akan membahayakan kepiting. Teritip tersebut berpengaruh pada pernapasan, aktivitas normal dan pertumbuhan kepiting. Prevalensi, intensitas rata-rata dan identifikasi pedunculate barnacle, Octolasmis spp. pada rajungan, Portunus pelagicus dari daerah pesisir Kuala Terengganu telah diteliti. Kekhasan lokasi dari berbagai spesies Octolasmis telah diperiksa. Kepiting telah diukur dan ditimbang. Kepiting dieuthanasi dengan cara dimasukkan kedalam es sampai tidak bergerak. Octolasmis diamati dari permukaan tubuh dan insang (branchial chamber). Octolasmis diamati pada tiap insang. Prevalensi dan intensitas rata-rata dihitung. Octolasmis diawetkan dalam alcohol 70 % dan mounting menggunakan Jeli gliserin untuk membuat slide permanen. Semua kepiting 13 ekor telah terinfestasi oleh empat spesies Octolasmis, yaitu 218 Octolasmis angulata, 191 Octolasmis warwickii, 16 Octolasmis tridens dan 218 Octolasmis lowei. Octolasmis angulate menunjukkan prevalensi paling tinggi (84,62%) dan prevalensi paling rendah adalah O. lowei (23,08%) dan O. warwickii(23,08%). Teritip menyerang insang, karapas, abdomen dan juga kaki jalan.Teritip paling sering ditemukan pada bagian insang 371 ekor (57,70%) dibandingkan pada bagian lain, 272 ekor (42,30%). Distribusi teritip pada penelitian ini menunjukkan bahwa bagian distal lebih rentan mengalami infestasi Octolasmis spp. Namun, teritip tidak menunjukkan kekhasan lokasi pada daerah insang bergantung pada arus air.

Abstract

AbstrakKajian karakteristik lingkungan dan kondisi fauna makrobentik di kawasan reboisasi mangrove Pulau Pramuka, Panggang dan Karya, Kabupaten Kepulauan Seribu telah dilakukan pada bulan April 2014. Kajian ini bertujuan sebagai data dasar dalam pengelolaan mangrove di Indonesia khsususnya pasca penanaman mangrove. Pengukuran karakteristik lingkungan dilakukan dengan cara insitu, sedangkan pengumpulan fauna makrobentik dengan membuat transek garis dan plot yang ditarik dari titik acuan (tegakan mangrove terluar) dan tegak lurus garis pantai sampai ke daratan. Hasil kajian memperlihatkan bahwa karakteristik lingkungan yang diukur tidak begitu berbeda antar stasiun dan juga tidak melebihi baku mutu untuk kehidupan biota laut. Sebanyak 6 spesies fauna makrobentik telah ditemukan dengan kepadatan yang bervariasi. Kepadatan tertingginya berada di Stasiun 3 (05.00 ind/m2) dan terendahnya di Stasiun 1 (02.00 ind/m2). Selain itu, fauna makrobentik Atilia (Columbella) scripta, Metopograpsus latifrons, Littoraria scabra, Saccostrea cucculata dan Cardisoma carnifex berasosiasi atau berkaitan erat dengan stasiun yang bersubstrat lanau maupun pasir. Selanjutnya parameter kualitas air yang paling menentukan distribusi dan kepadatan fauna makrobentik di kawasan reboisasi mangrove Pulau Pramuka, Panggang, dan Karya, Kabupaten Kepulauan Seribu adalah pH. AbstractThe study of the environmental characteristics and conditions of macrobenthic fauna in the mangrove reforestation area of Pramuka, Panggang, Karya, and the Seribu Islands was carried out in April 2014. This study aims at the basic data in mangrove management in Indonesia, especially after mangrove planting. Measurement of environmental characteristics is carried out by in-situ methods while collecting macrobenthic fauna by making line transects and plots drawn from the reference point (outermost mangrove stands) and perpendicular to the coastline to the mainland. The results of the study show that the measured environmental characteristics are not very different between stations and also do not exceed the quality standards for marine life. A total of 6 macrobenthic fauna species have been found with varying densities. The highest density is at Station 3 (05.00 ind/m2) and the lowest is at Station 1 (02.00 ind/m2). In addition, the macrobenthic fauna Atilic (Columbella) scripta, Metopograpsus latifrons, Littoraria scabra, Saccostrea cucculata and Cardisoma carnifex are associated or closely related to silt or sand substrates. Furthermore, the water quality parameters that most determine the distribution and density of macrobenthic fauna in the mangrove reforestation area of Pulau Pramuka, Panggang and Karya Seribu Islands District are pH.

Abstract

AbstrakKualitas garam sangat ditentukan oleh perlakuan dan penanganan yang diberikan pada saat pra produksi, proses produksi maupun pasca produksi. Kontaminan Pb dalam garam dapat bersumber dari lingkungan perairan laut sebagai bahan baku, tanah sebagai media / tempat produksi garam dan lingkungan udara dimana proses produksi garam berlangsung di lahan terbuka. Tujuan penelitian ini adalah untuk menganalisis kadar logam berat timbal (Pb) dalam garam di Kabupaten Pamekasan. Jenis penelitian ini adalah jenis deskriptif. Teknik pengumpulan data penelitian melalui observasi dan wawancara. Hasil observasi menunjukkan bahwa rata-rata kadar logam berat timbal (Pb) di Kabupaten Pamekasan masih di bawah batas maksimum yang telah ditentukan dalam SNI 3556-2010 dan SNI 7387-2009 yaitu <10 ppm dengan kadar Pb terendah 0,066 ppm dan tertinggi 0,162 ppm. Proses produksi garam kurang sesuai dengan standar yang telah ditetapkan. Oleh karena itu, perlunya penangangan yang baik pada pra produksi, proses produksi hingga pasca produksi pembuatan garam agar kadar Pb tidak meningkat.AbstractThe quality of salt is very determined by the treatment and handling given during the pre-production, production and post-production processes. Pb contamination in salt can be sourced from the marine environment as raw material in the process of making salt, the soil environment as a medium / place of salt production and the air environment where the salt production process takes place in an open area. The aim of research was to analyze levels of lead heavy metals (Pb) of salt in Pamekasan Regency. This research is a descriptive analysis. The techniques of data collecting of this research are observation and interview. Observations indicate that the average level of heavy metal lead (Pb) in Pamekasan regency is still below the maximum limit specified in SNI 3556-2010 and SNI 7387-2009 is <10 ppm which is the lowest grade of 0.066 ppm and grade the highest is 0.162 ppm. The salt production process is not in accordance with established standards The Therefore, the need for good handling in pre-production, production processes to post-production of salt production so that Pb levels do not increase.

This research was conducted using a completely randomized design method (CRD) as an experimental design. The treatments used were storaged Myxobolus koi spores at room temperature (28-34oC), Refrigerator (2-4oC), and Freezers (-5 to -10oC), with replications 6 times. This storage was carried out for 30 days. The main parameter observed was the percentage of damaged Myxobolus koi spores. The supporting parameters observed were the type of Myxobolus koi spore damage. Data analysis using ANAVA (Analysis of Variance) and continued with Duncan's Multiple Distance Test to find out the optimum temperature for storage of Myxobolus koi spores. Based on the results of the study, it was found that storage at different temperatures affected the percentage of damage to Myxobolus koi spores. The highest damage of Myxobolus koi spores occurred at room temperature (28-34oC) reaching 68.91% and the lowest damage value occurred at refrigerator (2-4oC) which was 29.91%. Myxobolus koi spores can be stored in a refrigerator and freezer
