Abstract

Sempu Island is a nature reserve that has fringing reef with percentage of living coral cover almost constant 37% from 2009 to 2016. Coral massive Porites lutea in this area has a growth rate about 1.09 cm/yr. in average and almost similar with others. Coral massive growth rate can be monitor through their skeletal annual banding. They have two type annual banding, low density for slow growth coral skeletal and high density for fast growth rate of coral skeletal. In this banding coral can record any environmental condition such as sea water temperature, tides and heavy metal. The aim of this research was to know the concentration of copper in Sempu Island Nature Reserve in the past used ICP-OES. The result showed that the Cu concentration in P. lutea skeletal band from 2009-2016 were: 5.213; 6.403; 5.825; 6.511; 6.132; 6.403; 6.467; 6.22 mg/kg. The coral skeletal can absorb the pollutant for hundred years, and it will give important information for palaeo environment that can used for climate modelling in the future.

Abstract

Coral reef is a massive natural building block that mainly composed of hard coral. In ecological view coral reef is the center of biological activity for shelter, foraging and feeding place. Porites lutea is a common coral in reef flat area such as in Pantai Kondang Merak. This coral can form a massive with hillocky colony surface and has a slow linear extension rate, that made this coral has long longevity. The annual growth band of coral skeleton provide information of pollutants in the coastal extending back over several years ago due to ability of coral aragonite traped trace metal from environment. The aim of this research was to determine the concentration of trace metals of Cd, Cu and As along with the coral annual banding. The heavy metals detection was performed using ICP-OES (iCAP 7400 Series). The concentration of Cd, Cu and As in sample 1 (KM1) were 2.236 mg/kg, 9.726 mg/kg, and 2.474 mg/kg, while sample 2 (KM2) were 1.989 mg/kg, 19.157 mg/kg, and 2,064 mg/kg respectively. Two ways mechanism of trace metals to be trapped in the coral skeleton are by direct mechanism when trace metals in a form dissolved ion that were uptaken by coral then stored into coral skeleton and by indirect mechanism when particulate metals ingested by plankton then eaten by coral through coral tissue. The tracing of heavy metal in coral is provided important information of environment condition of the sea from 2009 - 2015 that may be used for authority decision regarding pollutant ambient in the sea environment.

Abstract

TPI Sendang Biru berada di Kabupaten Malang memiliki potensi yang besar baik dalam bidang penyediaan pasokan ikan ataupun sarana prasarana penunjang lainnya. Pelabuhan perikanan tersebut dipersiapkan sebagai pusat pertumbuhan ekonomi perikanan di wilayah selatan Provinsi Jawa Timur. Pemerintah melalui Direktorat Jenderal Perikanan Tangkap Kementerian Kelautan dan Perikanan Tahun 2018 telah menyelesaikan relokasi pembangunan kios ikan berkonsep higienis pada wilayah tersebut untuk menunjang mutu hasil ikan dan harga jual ikan tetap tinggi.  Sejalan dengan hal tersebut Pemerintah Propinsi Jawa Timur saat ini melakukan pengembangan jalur lintas selatan untuk mempermudah aksesbilitas. Namun, adanya wabah pandemi Covid-19 saat ini menyebabkan dampak yang besar pada berbagai bidang termasuk bidang perikanan. Hal tersebut menyebabkan bukan hanya minat beli masyrakat yang menurun, namun keterbatasan jalur distribusi produk juga menghambat transaksi jual-beli masyarakat. Berdasarkan hal tersebut perlu dilakukan pelatihan dan pembinaan manajemen pemasaran produk-produk perikanan di TPI Sendang Biru berbasis media jual-beli online. Metode edukasi yang dilakukan adalah seminar dengan topik strategi pemasaran digital berbasis media sosial dan workshop berbasis toko online atau marketplace. Melalui program ini diharapkan dapat menjadi salah satu langkah awal dalam menghadapi tantangan-tantangan baru dalam penanggulangan pemulihan ekonomi pasca pandemi Covid-19, serta dapat memperluas jejaring pemasaran para nelayan atau penjual ikan di wilayah tersebut bahkan hingga keadaan normal kembali.

Abstract

Plastic is one of the most common pollutants found in marine waters. The direct negative impact of plastic waste on marine organisms is causing blockages in the digestive tract if eaten either intentionally or unintentionally. One of the efforts to reduce plastic waste is to build public awareness and readiness to actively participate in solving the problem of plastic waste. Therefore, Marine Science Study Program, FFMS, Universitas Brawijaya is dedicated to provide education about the dangers of plastic waste for aquatic communities and marine biota at a pioneering nature school for the Bajulmati Sea Turtle Conservation (BSTC) community in Bajulmati Beach, Malang Regency, East Java. In general, community service activities take place in online and offline manner. The educational methods given to students are a participatory and collaborative learning method, namely by providing an understanding of the material through class discussions and practical waste sorting activities in the field. The results of educational activities on the dangers of plastic waste can increase public knowledge and awareness, especially students at the BSTC nature school so that later it will have an effect on wiser plastic use behavior. Through this activity, it is expected that the resulted knowledge and awareness can foster a sense of love for the environment and can also affect a better use of plastic.

Abstract

Potensi pesisir yang besar menjadikan kawasan ini sangat rentan akan terjadinya perubahan. Faktor alami yang berpengaruh terhadap perubahan pesisir salah satunya yaitu gelombang ekstrim yang dapat menyebabkan abrasi. Pengukuran tinggi gelombang dilakukan dengan peramalan gelombang menggunakan periode ulang dangan metode weibull dan fisher typpet-1. Data gelombang di dapatkan dari ECMWF selama 10 tahun (2009-2018) yang kemudian diolah menggunakan Microsoft Excel. Hasil pengolahan data didapatkan bahwa gelombang memiliki tren naik pada tiap tahunnya. Pada 50 tahun (2068) kedepan tinggi gelombang dengan metode fisher typpet-1 senilai 2,73 m sedangkan dengan metode weibull senilai 3,01 m. Prediksi gelombang ini dapat dijadikan sebagai dasar dalam pembuatan skenario terhadap pengurangan dampak resiko bencana gelombang ekstrim di kawasan CMC Tiga Warna. Selain itu melalui penetapan kebijakan yang sesuai dalam mengelola wilayah yang aman, Yayasan Bhakti Alam Sendang Biru selaku pengelola dapat senantiasa memberikan pelayanan terbaik dan optimal kepada pengunjung atau wisatawan yang datang.
