Abstract

Mangroves are plants that grow between tidal lines. Mangrove forests have very important ecological andeconomic functions, but are very vulnerable to damage if they are not wise in maintaining, conserving andmanaging them. This research was conducted in Kampung Baru Village, Penajam District, Penajam PaserUtara Regency, East Kalimantan Province. The purpose of this study was to identify the types ofmangroves and to determine the ecological conditions of mangrove forest vegetation in the mangroveecosystem of Kampung Baru Village. The method used is the Transect Line Plot method. The dataobtained were then processed by community structure analysis. The types of mangroves found in fourstations in the mangrove ecosystem of the Kampung Baru, consist of nine types of mangroves, namely:Rhizopora mucronata, Rhizopora apiculata, Ceriops decandra, Avicennia marina, Nypa, Avicennia alba,Avicennia officinalis, Avicennia rumphiana, Sonneratia alba, and from four families, namely:Rhizophoraceae, Sonneratiaceae, Canthaceace and Arecaceace. The highest density value was Rhizophoramucronata, namely 1.04 ind/m2, with a relative density of 149.8%. The highest frequency value for Rhizophora mucronata was 400. The highest value for closure was Avicennia alba (100.12 m2). Importance value index of Rhizophora mucronata (151.82%), the lowest analysis of all stations wereCeriops decandra and Nypa species and had very abundant species diversity.

Abstract

The research aimed to know the characteristic of horizontal distribution to the Physical-Chemical parameters of surface water in Eastern Site of Balikpapan coastal area. Result of research indicate that current pattern that happened tend to make a move northerly during the year to South. Hoizontal Distribution and temperature and TSS tend to increase to come near coast, while dissolved oxygen and salinity tend to increase while turbidity, conductivity, pH, phosphate and ammonia tend to flatten from coast till 4 mile to the sea. Horizontal Distribution Cu (0,001 - 0,014 mg / l) tend to increase to come near coast, Hg content tend to smaller 0,0005 mg / l and still under standard of sea water quality. Bottom of the eastern site of Balikpapan coastal tend to flat.

Abstract

This study was aimed to analyze the prospects of development of the financial aspects of amplang processing and marketing channel of amplang processing business. The data was collected through a survey, completed by direct observation in the field and interviews with the respondents. The applied data analysis includes analysis of costs, revenues, income and business feasibility. The results showed the average revenue earned from amplang processing business is Rp. 7.040,000 per month or Rp. 70.400,000 per year, while the average cost of Rp. 4.623.167 per month or Rp. 46.238.333/year. The average income was found as much as Rp. 2.416.167/month or Rp. 24,161,667 / year. The value of the balance of revenue and cost (R/C) in the business of processing amplang is 1.54, which means that the amplang processing business is able to provide a gain of 1.54 of the cost. There are two pattern of marketing channel that were identified in the field, the first pattern is: amplang producer to retailer to consumer; and the second pattern is: amplang producer to consumer directly.

Abstract

Perifiton merupakan salah satu jenis mikroorganisme yang hidup menempel di permukaan lamun. Tujuan dari penelitian ini adalah untuk mengetahui kelimpahan perifiton rimpang Thalassia hemprichii di Perairan Pulau Kedindingan Kota Bontang. Penelitian ini berlangsung selama 9 bulan (Mei 2021-Januari 2022) menggunakan 4 stasiun. Kelimpahan total perifiton adalah 35.072 individu/cm2, ditemukan 41 jenis yang terdiri dari 8 kelas. Jenis perifiton yang memiliki kelimpahan tertinggi adalah Nitzchia Sp. Kelimpahan terendah adalah Stigeoclonium Sp. Kelimpahan perifiton tertinggi dan terendah ditemukan di Stasiun Barat dan Selatan

Abstract

Penelitian ini dilakukan pada bulan November 2017 – April 2018, penentuan stasiun penelitian didasarkan pada kelimpahan tumbuhan eceng gondok di Danau Semayang. Parameter utama adalah jenis dan kelimpahan perifiton epifit pada batang eceng gondok dan parameter sekunder kualitas air di Danau Semayang. Hasil penelitian ditemukan 9 kelas perifiton epifit dengan 83 spesies. Tujuan penelitian ini adalah untuk mengetahui jenis-jenis epifit yang memanfaatkan batang tumbuhan eceng gondok (Eichornia crassipes) sebagai habitatnya, mengetahui kelimpahan, indeks keanekaragaman, keseragaman, dan dominansi serta faktor pembatas yang mempengaruhi kelangsungan hidup perifiton di perairan. batang eceng gondok (Eichornia crassipes). Berdasarkan hasil perhitungan selama penelitian, nilai korelasi antara kerapatan tegakan eceng gondok dengan kelimpahan perifiton ditemukan sangat tinggi (0,9968) pada bulan November. Hasil perhitungan CA Stasiun I terdiri dari 6 kelas dari 24 spesies, Stasiun II terdiri dari 6 kelas dari 34 spesies, Stasiun III terdiri dari 5 kelas dari 24 spesies. Hasil PCA mencirikan Stasiun I dengan nilai kekeruhan yang tinggi di perairan. Stasiun II dengan nilai kedalaman yang tinggi, Stasiun III dengan nilai temperatur air yang tinggi

Abstract

Penelitian ini dilaksanakan pada bulan Mei 2021-Januari 2022 di Pulau Kedindingan Kota Bontang, propinsi Kalimantan Timur. Tujuan penelitian ini adalah untuk mengetahui hubungan kondisi lamun dengan sampah laut di perairan Pulau Kewallan Kota Bontang Kalimantan Timur. Jumlah stasiun pengamatan di penelitian ini adalah 4 stasiun yang terdiri dari zona intertidal dan subtidal. Pengumpulan sampah di ekosistem lamun menggunakan metode transek kuadran 50 x 50 cm. Pengumpulan sampah dilakukan sebanyak tiga kali dengan dua kali pengulangan pada titik air surut tertinggi dan terendah. Metode analisis yang digunakan adalah uji korelasi. Berdasarkan hasil pengamatan dan analisis, ditemukan bahwa volume sampah yang berbeda-beda. Volume sampah tertinggi ditemukan di stasiun Barat dan Selatan dengan rata-rata volume 14.700 cm³. Sedangkan volume sampah terendah terdapat di stasiun Timur dan Utara dengan rata-rata volume 9.800 cm³. Secara umum, tidak ditemukan korelasi hubungan korelasi antara sampah dan tegakan lamun (p>0,05) berdasarkan analisis korelasi.

Abstract

Plankton as a basic component in the structure of life in the waters, spesifically as water producers can be used as one of the parameters in monitoring the quality of the aquatic environment. The existence of aquatic tourism activities and quantitative and qualitative plankton can be used to determine the fertility of a waters, by measuring the abundance and distribution of plankton found at each depth. The research station is divided into three sites, site A is the source of the entry and exit of sea water, site B is in the middle of the lake, and site C is located close to the freshwater spring. Based on the results of research in the waters of Danau Dua Rasa Labuan Cermin, 8 classes of plankton were obtained with 24 species, there are the Chlorophyceae, Cyanophyceae, Chrysophyceae, Dinophyceae, Mastigophora, Crustacea classes. Sarcodina and Rotatoria. The Danau Dua Rasa Labuan Cermin are included in the Mesotrophic waters group. Because the abundance value reaches 9,513 ind/L, in other words, Labuan Cermin waters have a moderate fertility level that can support the breeding and survival of aquatic organism and the continuity of a good photosynthesis process.
