Abstract

Sebaran sedimen tersuspensi (Total Suspended Solid (TSS)) dapat dipelajari secara horizontal maupun vertikal. Akumulasi sedimen tersuspensi (TSS) secara horizontal sangat dipengaruhi oleh arus permukaan maupun gelombang yang dibangkitkan oleh angin. Keterdapatan TSS ini diduga berpengaruh terhadap sebarannya pada profil vertical. Kedua kondisi sebaran sedimen tersuspensi (TSS) berpengaruh terhadap optimalisasi penetrasi cahaya matahari di perairan. Sedimen tersuspensi (TSS) menjadi salah satu factor fisika yang penting sebagai indicator kondisi perairan. Penelitian ini bertujuan untuk mengetahui sebaran Total Suspended Solid (TSS) di perairan Kabupaten Bangkalan. Materi utama yang digunakan dalam penelitian ini adalah contoh air dan data parameter lingkungan (pasang surut dan kecerahan) yang diambil pada 7 stasiun pada bulan Agustus-September 2013 di Perairan Selat Madura, Kabupaten Bangkalan. Metode gravimetric (SNI-06-6989.3-2004) digunakan untuk analisa Total Suspended Solid (TSS). Data parameter lingkungan dianalisa secara deskriptif. Analisa TSS menunjukkan nilai yang berbeda pada beberapa stasiun penelitian untuk setiap minggunya. Konsentrasi TSS terendah sebesar 35 mg/L (Stasiun 3, profil permukaan, minggu pertama) dan tertinggi sebesar 620 mg/L (Stasiun 4, profil dasar, minggu pertama). Secara umum, konsentrasi TSS secara vertikal (dari permukaan-dasar) cenderung semakin besar, diduga dipengaruhi oleh jenis substrat dan parameter arus yang berpeluang untuk menimbulkan pengadukan di profil dasar. Kondisi lingkungan (kecerahan dan arus) menunjukkan bahwa daerah dengan konsentrasi TSS yang tinggi cenderung memilki nilai kecerahan yang rendah dengan kecepatan arus yang lebih besar.Kata Kunci: kecerahan, pola arus, Total Suspended Solid (TSS) DISTRIBUTION OF TOTAL SUSPENDED SOLID (TSS) IN THE VERTICAL PROFILE IN THE MADURA STRAIT WATERS BANGKALAN DISTRICTABSTRACTDistribution of suspended sediment (Total Suspended Solid (TSS)) can be studied through horizontal and vertical. Accumulation of suspended sediment (TSS) horizontally greatly influenced by surface currents and waves generated by the wind. TSS discovery is supposed to influence the spreading on a vertical profile. The second condition of distribution of suspended sediment (TSS) effect on optimizing the penetration of sunlight in the water. Suspended sediments (TSS) became one of the important physical factor as an indicator of water conditions. This study aims to determine the distribution of Total Suspended Solid (TSS) in the waters of Bangkalan. The main material used in this study is an example of water and environmental parameter data (tidal and brightness) taken at 7 stations in August-September 2013 in the Madura Strait, Bangkalan. Gravimetric method (ISO-06-6989.3-2004) is used for the analysis of Total Suspended Solid (TSS). Environmental parameters data were analyzed descriptively. TSS analysis shows different value on some of the research station for TSS. Concentration per week low of 35 mg / L (Station 3, surface profile, the first week) and the highest was 620 mg / L (Station 4, the basic profile, the first week). In general, concentrations of vertical TSS (from surface-basic) tends to be greater, might be influenced by the type of substrate and flow parameters are likely to cause agitation in the basic profile. Environmental conditions (brightness and current) shows that areas with high concentrations of TSS tend to have the value of a low brightness with the larger speed of currents.Keywords: brightness, current patterns, Total Suspended Solid (TSS)

Abstract

Bandeng (Chanos chanos, Forskal) merupakan salah satu komoditas yang strategis untuk memenuhi kebutuhan protein yang relatif murah dan digemari oleh konsumen di Indonesia.  Bandeng sebagai bahan pangan, merupakan sumber zat gizi yang penting bagi proses kelangsungan hidup manusia Tujuan penelitian ini adalah untuk mengetahui komposisi kimia daging ikan bandeng yang berasal dari habitat yang berbeda yaitu air tawar dan air payau. Penelitian dilakukan dengan dua tahap yaitu preparasi sampel saat transportasi dan preparasi bahan baku untuk memisahkan daging, kulit, tulang dan jeroan. Analisa yang dilakukan yaitu analisis proksimat, asam amino, asam lemak, mineral dan vitamin. Hasil yang didapatkan bahwa ikan bandeng dari dua habitat memperoleh rendemen yang berbeda. Rendemen ikan bandeng air tawar sebesar 38,5%, sedangkan air payau sebesar 50,8%. Ikan bandeng kaya akan sumber protein (20-24%), asam amino, asam lemak, mineral dan vitamin. Komposisi asam amino tertinggi yaitu glutamat sebesar 1,386% (air tawar) dan 1,268% (air payau). Asam lemak tidak jenuh tertinggi oleat 31-32%, mineral makro pada daging ikan bandeng yaitu: Ca, Mg, Na dan K. Mineral mikronya terdiri dari Fe, Zn, Cu, Mn.

Abstract

Efek negatif dari kegiatan industri telah menyebar tidak hanya di darat tapi juga di ekosistem perairan, termasuk laut. Polusi dari kegiatan industri ke air laut terutama heavymetal, menjadi masalah di seluruh dunia. Penelitian tentang makroalga Gracilaria sp. menyerap Timbal telah dilakukan dalam percobaan 6-hari untuk menyelidiki kemampuan potensial sebagai agen bioremediasi. Penurunan konsentrasi Timbal ditemukan dalam air laut selama percobaan 144 jam diukur dalam suhu kamar. Percobaan ini menggunakan Rancangan Acak Lengkap (RAL) dengan dua faktor, amonium dan Timbal (Pb). Memimpin digunakan dalam tiga tingkat (0,0, 0,5, dan 1 ppm) dan amonium digunakan dalam satu tingkat (0,5 ppm). Setiap pengobatan menggunakan tiga ulangan. Hasil akhir menunjukkan bahwa konsentrasi Timbal dalam Gracilaria sp. selama pengobatan A (0.00 ppm dari amonium) naik ke 0,03 ppm, perlakuan B (0,05 ppm dari amonium) naik 0,55 ppm, perlakuan C (0,50 ppm dari amonium) naik ke 1,77 ppm dan perlakuan D (1 ppm dari amonium) naik ke 2.94 ppm. Konsentrasi Timbal ditemukan dalam air laut menurun secara berkala. Pada periode 96 jam eksperimental, konsentrasi Timbal di semua perawatan mencapai 0.00 ppm.Kata kunci: Ammonium, Bioremediasi, Gracillaria, Timbal (Pb) THE ABILITY OF Gracilaria sp. AS BIOREMEDIATION AGENT IN ABSORBING HEAVY METAL PbABSTRACTThe negative effect of industrial activities has been spread out not only in terrestrial but also in aquatic ecosystems, including ocean. The pollution from industrial activities to the seawater especially heavymetal, become problem all over the world. Research on macroalgae Gracilaria sp. to absorb Lead has been conducted in 6-day experiment to investigate the potential ability as bioremediation agent. The decline of Lead concentration found in the seawater during 144 hours experiment measured in room temperature. This experiments used Completely Randomized Design (CRD) with two factors, ammonium and Lead (Pb). Lead used in three level (0.0, 0.5, and 1 ppm) and ammonium used in one level (0.5 ppm). Each treatment used three replicates. Final results showed that Lead concentration in Gracilaria sp. during treatment A (0.00 ppm of ammonium) rises to 0.03 ppm, treatment B (0.05 ppm of ammonium) rises to 0.55 ppm, treatment C (0.50 ppm of ammonium) rise to 1.77 ppm and treatment D (1 ppm of ammonium) rise to 2.94 ppm. The concentration of Lead found in seawater declined periodically. In 96 hours experimental period, the concentration of Lead in all treatments reached 0.00 ppm.Keywords: Ammonium, Bioremediation, Gracillaria, Lead (Pb)

Abstract

Mangrove forest at the Kudai Estuary, Bangka has destructed, caused by tin mining unconventional  activities (TI). Mangrove conversion to non-conventional mining affected directly or indirectly for mangrove (Rhizophora apiculata) ecosystem. Based on the condition, rehabilitation needed to do straightforward to sustainability and sustainable aspect. Aims of the study were cultivated planting analysis of mangrove at Kudai Bangka Regency and to observed the participation on mangroves planting. This research was conducted on April 2010 to August 2011. Planting has done on tin post-mining Kudai Estuary, Bangka. The results showed that the seeding accomplishment are 100% and planting 99,6%. Substrat composition on tin post-mining area at Kudai Estuary are 60% sand, 30% clay and suitable substrat for mangrove (Rhizophora apiculata) growth. The seedling accomplishment and planting were supported by environmental parameters, such as pH, salinity, substrate, and organic materials.Keywords: Devastation, Unconventional Tin Mining (TI), Planting, Rhizophora apiculata
