Abstract

Ekosistem terumbu karang merupakan salah satu organisme laut yang rentan terhadap perubahan lingkungan perairan. Salah satu dampak akibat perubahan lingkungan tersebut adalah munculnya berbagai penyakit dan gangguan kesehatan karang. Penelitian ini bertujuan untuk mengetahui kondisi terumbu karang dan mengindetifikasi jenis-jenispenyakit dan gangguan kesehatan yang mengancam ekosistem terumbu karang di perairan Desa Langgapulu. Metode transek garis (line intercept transect) sepanjang 50 m digunakan untuk menggambarkan kondisi terumbu karang dengan melihat persentase penutupan karang hidup, karang mati, alga, dan keberadaan biota lainnya. Metode belt transek  dengan ukuran 5 m x 50 m digunakan untuk mengidentifikasi penyakit dan gangguan kesehatan karang, pada 4 stasiun pengamatan. Hasil penelitian menunjukkan bahwa kondisi terumbu karang di perairan tersebut dalam kategori sedang hingga buruk/rusak. Jenis penyakit karang yang ditemukan pada perairan ini yaitu Black Band Disease (BBD), Brown Band Disease (BRBD), Dark Spots Disease (DSD), Pink Boctch (PB), Skeletal Eroding Band (SEB), dan White Syndromes (WS). Gangguan kesehatan karang umumnya disebabkan karena pemutihan karang (Bleaching), Crown of Thorns Starfish, Growth Anomalies, Pigmentation Response, Sediment Damage, dan Tube Former. Penurunan kualitas lingkungan perairan sangat berperan terhadap munculnya berbagai penyakit dan gangguan terhadap kesehatan karang, yang berdampak pada gangguan secara fisiologis bagi biota karang.

Abstract

Studi analisis vegetasi, estimasi biomasa dan stok karbon ekosistem mangrove sangat penting dilakukan untuk menentukan kondisi ekosistem dan kemampuan ekosistem mangrove dalam menyerap karbon dan menyimpannya ke dalam biomassanya. Tujuan dari penelitian ini adalah untuk mengetahui kondisi vegetasi mangrove, persentase tutupan vegetasi, status biomassa permukaan (AGB), serta potensi stok karbon yang tersimpan di vegetasi mangrove di pesisir Kecamatan Latambaga, Kabupaten Kolaka. Penelitian ini dilakukan pada bulan Agustus 2019. Metode penelitian menggunakan transek kuadrat untuk menghitung kerapatan mangrove, selanjutnya dibandingkan dengan metode Hemispherichal Photography untuk mengukur persentase penutupan vegetasi mangrove berbasis pemisahan antara pixel langit dan pixel vegetasi. Data AGB dihitung berdasarkan data diameter batang mangrove (Diameter at Breast Heigh/DBH) dan persamaan allometrik dari setiap spesies. Data stok karbon dihitung dengan menggunakan konstanta karbon dari bahan organik dan data biomassa (AGB). Hasil penelitian menunjukkan, kerapatan mangrove tertinggi secara berturut-turut terdapat di stasiun 2 (5299,99 ind/ha2), stasiun 1 (3466,66 ind/ha2),  dan stasiun 3 (3066,66 ind/ha2). Persentase tutupan mangrove berbasis pixel kanopi  menunjukkan hasil yang sama dengan kerapatan mangrove, dimana persentase tutupan mangrove tertinggi terdapat di stasiun 2 (84,0716%), stasiun 1 (81,5368%), dan stasiun 3 (80,9978%). Ekosistem mangrove yang ada lokasi tersebut dalam kondisi baik dengan kerapatan  dan persentase tutupan yang cukup tinggi. Komposisi penyusun vegetasi mangrove yang ada di Kecamatan Latambaga didominasi oleh mangrove jenis Rhizophora apiculata dan Rhizophora mucronata dengan kelas pertumbuhan sapihan (DBH < 10cm)  dan tiang (DBH < 20 cm). Meskipun dalam kondisi yang baik, ekosistem mangrove di pesisir Kecamatan Latambaga mengalami ancaman alih fungsi lahan menjadi tambak. Total AGB tertinggidi stasiun 1 (226,76 ton/ha), diikuti oleh stasiun 3 (181,47 ton/ha), dan stasiun 2 (76,06 ton/ha). Stok karbon berbanding lurus dengan data AGB. Total stok karbon tertinggi juga terdapat pada stasiun 1 (106,57 ton/ha), diikuti oleh stasiun  3 (85,29 ton/ha), dan stasiun 2 (35,75 ton/ha).

Abstract

Holimombo Village is an area with a karst landscape, where the problems in the area are the absence of surface water sources. Based on these problems, the research objective is to identify the potential of groundwater as a source of raw water for the community in Holimombo Village, Wabula District, Buton Regency. The research is a quantitative descriptive study, where the subsurface resistivity data was used. The Field observation techniques were used for data collecting in this study, where the measurement of the subsurface resistivity value uses a set of geoelectrical resistivity meters. The results of the geoelectric measurements will then be processed using the Res2DinV application. The subsurface resistivity measurements were carried out in four different paths. Based on the measurement results, the subsurface resistivity values at the research site in Holimombo Village, Wabula District, Buton Regency vary, ranging from 6.64 Ωm to above 1000 Ωm. Areas that have ground water potential are on the line 4 with coordinates 5°33,751' S and 122°53,112' E. The layer at this point is weathered limestone in the form of sand and gravel which has groundwater potential because it has a resistivity value of 50-500 Ωm. The potential for groundwater at that point is quite a lot with a thickness of 27.7 m. Therefore, this potential can be utilized by the Holimombo Village community as a source of daily raw water. AbstrakDesa Holimombo merupakan daerah dengan bentang alam kars, dimana permasalahan di daerah tersebut adalah tidak adanya sumber air permukaan.
