Abstract

Penelitian ini bertujuan untuk mengetahui kualitas air secara fisika, kimia dan biologi serta laju sedimentasi pada Saluran Irigasi di Kecamatan Long Mesangat. Analisis kualitas air secara fisika, kimia dan biologi dengan menggunakan Indeks Storet. Sedangkan laju sedimentasi dengan menghitung debit air saluran irigasi, dan total padatan tersuspensi (TSS). Hasil penelitian menunjukan bahwa kualitas air pada saluran irigasi adalah memenuhi standar baku mutu kelas III dan IV yang peruntukannya budidaya perikanan dan pertanian. Kualitas air memenuhi standar baku mutu untuk Kelas I, II, III dan IV yaitu Parameter fisika dengan rata-rata suhu 31,7OC, TDS : 0,016 mg/L, TSS : 19,61 mg/L, dan Kekeruhan : 62,76 NTU. Sedangkan parameter kimia adalah memiliki rerata BOD-5 1,2 mg/L, NO3 8,22 mg/L, Nitrit 0,023 mg/L, dan Sulfat 29,43 mg/L). Parameter kimia yang tidak memenuhi standar baku mutu untuk Kelas I dan II adalah rerata kadar Fe 0,94 mg/L, kadar Cl 3,91 mg/L, kadar COD 25,03 mg/L, dan DO 4,85 mg/L. Parameter biologi total coliform tidak memenuhi ( S.Primer : 513,33/100ml, S.Sekunder : 670/100ml, S.Tersier : 1126,67/100ml). Laju sedimentasi pada saluran irigasi berturut-turut adalah 0,724 ton/hari, 0,451 ton/hari dan 0,021 ton/hari.

Abstract

From the results of the study it can be concluded that mangrove ecosystems in the village of Tanjung Limau, Muara Badak District, were found in 5 types, namely (R. apiculata, A. alba, N. fruticans, C. tagal and S. alba). With species density ranging from 1-68 individuals / ha and thickness of mangroves between 160-200 m. While the results of the tourism suitability index obtained categories according to the carrying capacity of the region 8-10 people / day. There are 3 management strategies and development of mangrove ecotourism in Tanjung Limau Village, namely: first to make proposals to the private sector and the government in improving the management and development of mangrove ecotourism through capital assistance and improvement of tourism facilities and infrastructure in Tanjung Village, secondly to increase / encourage government participation in helping the community to manage and develop mangrove ecotourism and thirdly to coordinate and collaborate between communities, NGOs, the private sector and the government in managing and developing mangrove ecotourism.

Abstract

A first survey  on a community marine species in  river of Mahakam East Kalimantan was performed in December 2015 and May 2016. Fish samplings were carried out from two locations the lower and the middle part of Mahakam. Whilst hydrometric observation of current velocity, water depth and tide was measured not only at the locations but also along the river from 2013 to 2017, tide was only observed in the lower part of Mahakam.  However, marine fish species were recognized to reach up the middle part of Mahakam, 230 km from coastline.  To describe a community fish structure and its dissimilarity of the two surveyed locations, diversity and bray Curtis index were applied.  Almost 15 marine fish species identified in river of Mahakam was demersal fish and index of the similarity of marine fish community between the locations only 0.106.

Abstract

Coral reefs found in Tihik-Tihik village shows moderate coral reef status with indications of greater potential for damage so that protection efforts are needed. This research aims to analyze the abundance and community structure of plankton in reef ecosystems natural and artificial reefs. Sampling was carried out in the month of October – November 2020 at four stations at high and low tide with using a plankton net, then identified in the Water Quality Laboratory FPIK Unmul. The identified plankton consisted of 7 classes, namely, Bacillariophyceae (21 species), Conjugatophyceae (3 species), Copepoda (8 species), Cyanophyceae (1 species), Dinophyceae (10 species), Oligotrichea (3 species), Trebouxiophyceae (1 species). The highest total abundance of artificial reef ecosystems was at station 2 pairs with a total of 6741 ind/l. The diversity index (H') ranged from 2.12 to 2.22. The uniformity index (E) ranged from 0.92 – 0.96. The dominance index (D) ranges from 0.11 to 0.13. Sorenssen similarity index ranged from 29 – 68%.

Abstract

Ekosistem mangrove yang ada terus mengalami perubahan selama 20 tahun terakhir. Perubahan ini perlu dipetakan untuk mengetahui letak dan luasan perubahan mangrove di Balikpapan Barat dari tahun 2009 hingga 2015. Penelitian ini bertujuan untuk menganalisis perubahan tutupan lahan pada hutan mangrove di kawasan Balikpapan Barat periode 1995-2015. Penelitian ini menggunakan data Penginderaan Jauh yaitu Citra Satelit Landsat 5, Landsat 7 Enhanced Thematic Mapper (ETM+) dan Landsat 8 Operational Land Imager (OLI). Sebaran tutupan lahan mangrove dipetakan secara digital melalui interpretasi citra satelit Landsat 5, Landsat 7 Enhanced Thematic Mapper (ETM+) dan Landsat 8 Operational Land Imager (OLI) menggunakan metode Supervised Classification. Hasil interpretasi tersebut kemudian dipetakan (layout) untuk memberikan informasi agar lebih mudah dibaca dan dipahami. Hasil klasifikasi ini kemudian diuji akurasi lapangan untuk mengetahui dimana terjadi perubahan, pola perubahan dan faktor-faktor penyebab perubahan tersebut. Hasil penelitian menunjukkan bahwa perubahan tutupan lahan hutan mangrove/konversi hutan mangrove dari tahun 1995 ke tahun 2015 menjadi vegetasi non-mangrove sebesar 6,97 ha, konversi lahan hutan mangrove menjadi lahan terbuka sebesar 3,44 ha, konversi lahan Lahan hutan mangrove menjadi pemukiman seluas 16,72 ha dan konversi lahan hutan mangrove menjadi badan air seluas 11,40 ha. Perubahan mangrove yang terjadi memiliki pola acak (penyebaran tidak merata) akibat meningkatnya faktor pertumbuhan manusia dan alih fungsi lahan menjadi tambak.
