Abstract

The high level of human activity in coastal areas has had an impact on seagrass beds. The advancement of satellite imaging technology makes monitoring seaweed conditions even easier. The purpose of this study was to identify the spectral reflectance patterns of different seagrass cover levels and make it the basis for mapping the seagrass condition on Barranglompo Island. Based on google earth has been determined 4 sampling stations that represent the spread of seagrass on Barranglompo Island. Each station is divided into 4 sub-stations from land to sea. Sampling of seagrass cover was carried out by the McKenzie (2003) method modified by close sampling, to 30 x 30 square meters following the spatial resolution of Landsat image 8. Each observation point was estimated the percentage of seagrass cover and the dominant species. Digital seagrass pixel extraction is performed from band 1 to 7 landsat 8 according to point position in the field and then grouped by cover class and condition. Seagrasses found in Barranglampo Island are 8 species: Enhalus acoroides, Thalassia hemprichii, Halophila ovalis, Cymodocea rotundata, Cymodocea serulata, Halodule uninervis, Halodule pinifolia and Syringodium isoetifolium. In general, Enhalus acoroides and Thalassia hemprichii have higher closure than other seagrass species. The spectral reflection of seagrass landscape imagery 8 OLI channel 1 - 7 is good enough to show the seagrass condition in bad category, good enough, and good. Spectral reflection of the seagrass has a peak on the green channel. The worse the seagrass condition the higher the spectral reflection. Seagrass with bad conditions has a low cover so that other substrates such as sand will contribute to the spectral value recorded by satellite sensors. This result will facilitate mapping of seagrass condition on small islands by using Landsat 8 OLI image.Keywords: seagrass condition, spectral reflection, landsat 8, South Sulawesi

Abstract

Coral reefs and seagrass are natural fortress for small islands from waves and ocean currents. The spatial distribution of these benthic substrate should be known and monitored regularly. This study aims were to map existing benthic substrates on the reef flat of Bontosua Island, determine the spatial composition and develop index ratio. Benthic substrates were surveyed using geotagging technique. Their distribution were estimate using Quickbird image that was rectified and classified using ISOcluster method and validate by 240 selected photos. The seagrass were surveyed at 8 stasions to record percent cover and species composition. Depth profiles were track along 10 reef flat line segment. Bontosua Island has an elongated shape from South to Northwest. This study had produced a benthic substrate distribution map with thematic accuracy 76%. Total area able to map were 54.2 hectares. About 43% benthic substrates at Bontosua were mixture of coral rubble, seagrass and algae, 20% was mixture of rubble and algae, 16% dominated by seagrass, 13% mixture of sand and seagrass and 8% substrate were dominated by live coral. There were eight seagrass species found with average percent cover 37.2 ± 12.5 percent. The spatial ratio of live coral, seagrass and mixed substrate for West side reef flat was 2:20:49 and 1:9:9 for East side. This indicate that the distribution of benthic substrates on the West side is much wider than on the East side. This approach potentially applied to study the relationship between benthic substrate composition and the deformation of small islands.

Abstract

Suatu model batimetri digital dapat dibangun melalui interpolasi sejumlah besar titik kedalaman hasil pemeruman. Studi ini menggunakan dua skenario pengolahan yaitu menggunakan keseluruhan data perum dan menggunakan data perum terpilih. Pada setiap skenario pengolahan data, ada tiga metode interpolasi yang dibandingkan yaitu metode inverse distance to power, kriging dan minimum curvature.Nilai RMSE yang didapatkan dari masing-masing interpolator pada setiap skenario tersebut ternyata cukup bervariasi. Secara umum metode Kriging lebih efektif digunakan untuk menghasilkan gambar kontur kedalaman perairan dibandingkan dengan metode lainnya. Hasil studi ini memperlihatkan perlunya penanganan data agar pola suatu unsur spasial (kontur kedalaman) dapat ditampilkan secara lebih baik.Kata Kunci: interpolasi, kriging, inverse distance to power, minimum curvature,batimetri

Abstract

The high cost of repair and maintenance of outboard engines is one of the big problems experienced by fishermen, their lack of knowledge about engine repair and maintenance results in them having to spend more money for their repair and maintenance costs. For this reason, the purpose of this service program is to train and guide the community on outboard engine repair and maintenance methods. The activity was carried out on August 21, 2021 in Topejawa Village, Mangarabombang District, Takalar Regency. This activity involved more than 20 participants from 2 (two) fishermen groups in Topejawa Village, Takalar. This activity was held in the coastal area of ​​Topejawa Village and was opened directly by the Representative of the Marine and Fisheries Service of the Takalar Government. From the results of the qualitative analysis, it was found that before the activity was carried out, the understanding of the community/partners of the working principle and machine operation, as well as machine maintenance and repair techniques were in the range of 30-50%. After that, the proportion of people's understanding increased by 75-90%. In addition, the fishermen also save on the cost of repairing and maintaining boat engines, which in turn increases the productivity and welfare of the fishing community, especially in the place where activities was carried out.

Abstract

Ekosistem mangrove mempunyai kemampuan yang sangat efektif dalam mengurangi konsentrasi gas karbon dioksida (CO2) di alam. Estimasi stok karbon dapat dilakukan menggunakan teknologi penginderaan jauh yang mengacu pada indeks vegetasi dari suatu area. Penelitian ini dilaksanakan pada bulan Maret sampai Desember 2020 di Pulau Nunukan, Kabupaten Nunukan, Kalimantan Utara. Penelitian ini bertujuan untuk mengestimasi stok karbon permukaan (Above Ground Carbon) di Pulau Nunukan menggunakan citra Landsat-8 dan pengukuran in situ. Pengukuran nilai cadangan karbon di lapangan dengan menggunakan persamaan alometrik yang dihitung berdasarkan jenis vegetasi. Penggunaan citra Landsat-8 OLI dilakukan setelah pra-processing dengan koreksi geometrik dan radiometrik. Selanjutnya citra Landsat-8 OLI dilakukan klasifikasi unsupervised untuk menentukan batas wilayah sebaran mangrove, lalu ditransformasi ke persamaan Normalized Difference Vegetation Index (NDVI). Nilai NDVI dengan nilai stok karbon pada setiap titik sampel diuji dengan 3 jenis regresi. Dari 3 jenis uji regresi nilai R2 tertinggi ditetapkan sebagai persamaan untuk membangun model estimasi stok karbon permukaan. Dua jenis model estimasi stok karbon yang dibangun, yaitu model yang menggunakan seluruh jenis yang teridentifikasi sebagai sampel, dan model yang hanya menggunakan jenis dominan yang ditemukan pada wilayah kajian. Jenis mangrove yang mendominasi di Pulau Nunukan yaitu Rhizophora apiculata, sehingga jenis tersebut digunakan sebagai sampel dalam model estimasi stok karbon jenis dominan. Nilai R2 yang tertinggi dari persaaman regresi yang digunakan untuk mengestimasi stok karbon yaitu persamaan regresi kuadratik. Sehingga persamaan regresi kuadratik digunakan sebagai dasar model estimasi cadangan karbon. Nilai estimasi stok karbon permukaan (C) yang menggunakan model estimasi stok karbon seluruh jenis adalah 6.401.988,95 ton, sedangkan nilai estimasi stok karbon untuk model estimasi stok karbon jenis dominan adalah 5.616.404,46 ton.

Abstract

Desa Turungang, Kelurahan Langnga, Kecamatan Mattirosompe, Kabupaten Pinrang merupakan sebuah desa yang berbatasan dengan selat Makassar. Karena lokasi geographis yang berbatasan dengan laut ini, maka sebagian besar penduduk desa Turungang berprofesi sebagai nelayan. Untuk menangkap ikan, para nelayan biasanya menggunakan kapal ikan, sedangkan untuk mendinginkan dan mengawetkan hasil tangkapan, nelayan menggunakan es balok. Namun demikian, penggunaan es balok sangat tidak efektif karena lama dan pendinginannya yang terbatas sehingga nelayan tidak dapat beroperasi lebih jauh dan lebih lama karena harus segera membawa pulang hasil tangkapan ke darat untuk di jual sebelum ikannya menjadi tidak segar. Untuk itu, pada program pengabdian ini akan dilakukan penerapan teknologi pendingin ikan berbasis energi surya pada kapal ikan yang dimiliki oleh masyarakat nelayan. Dengan menggunakan teknologi ini, nelayan dapat beroperasi lebih jauh dan lebih lama karena teknologi ini akan mendinginkan ikan secara optimal selama nelayan melaut. Selain itu, karena memanfaatkan energi terbarukan, biaya operasional yang harus dikeluarkan juga sangat rendah dan nelayan dapat juga memanfaatkan listik oleh sistem ini untuk kepentingan lain seperti untuk penerangan atau komunikasi (radio).
