Abstract

The mangrove ecosystems are one type of coastal ecosystem found along coastlines and river estuaries that are influenced by tides and inundation. Segara Anakan Lagoon, Cilacap as one type of coastal ecosystem has a protection function, coastal area buffer, and cultivation area function that must be supported from the aspects of policy and institutions, communication, and coordination. This study aims to identify the role of stakeholders and the relationship between stakeholders in mangrove ecosystem management in Segara Anakan Lagoon, Cilacap. The research method used was a survey and interview method analyzed with MACTOR software. The results showed that there were 18 stakeholders who involved in mangrove ecosystem management in Segara Anakan Lagoon, Cilacap. The stakeholders are classified into main stakeholders, key stakeholders, and supporting stakeholders using the objective of mangrove management as key activities such as silvofishery, mangrove conservation, fishing activity, industry activity, etc. The level of convergence between stakeholders was 96.1% and the level of divergence was 3.9%. These results indicate a relatively low potential for conflict between stakeholders. The research can be used as a model relation between stakeholders to support the management activity of Segara Anakan Lagoon.

Abstract

Mangrove ecosystem in Segara Anakan Lagoon (SAL) Cilacap as a typical and specific semiclosed estuary. SAL  is dominated by many species like as Rhizophora spp., Sonneratia spp., Bruguiera spp., Avicennia spp., and other species. The normalized different vegetation index (NDVI) and dominant vegetation index (DVI) are a suitable method to support the mapping analysis of mangrove structure and mangrove density.  This research aimed to develop mapping of mangrove species distribution, density and dominated species using NDVI and DVI.  The method of this research used NDVI analysis using satellite imagery 2017-2020 and domination vegetation with line and quadrat transect method. The results showed that  West Segara Anakan had mangrove dense (25 %), moderate density (25 %), rare density (50%) and East Segara Anakan had mangrove dense (43,86 %), moderate density (47.99 %), rare density (8,24 %).  Based on domination species showed that East Segara Anakan was dominated by Rhizophora stylosa (233-1633 trees ha-1), Rhizophora apiculata (100-1067 trees ha-1), Nypa frutican (50-2775 trees ha-1), whereas West Segara Anakan was dominated by Nypa frutican (565-2333 trees ha-1), Avicennia marina (198-933 trees ha-1), Sonneratia caseolaris  (132-700 trees ha-1) and Avicennia alba (107-1000 trees ha-1). Keywords : Mangrove density, mapping analysis, Segara Anakan Lagoon, NDVI and NDWI

Abstract

Western Segara Anakan Lagoon (WSAL) is a semi-enclosed lagoon located in the Cilacap, Central Java Province, Indonesia which has two outlets called pelawangan. West Pelawangan is an open channel from WSAL and the Indian Ocean, which has vast sediment input. It impacts the sediment deposits and delta formations in WSAL. This research aimed to determine the sediment characteristics deposited in the WSAL specifically in the delta formation area, and the mean size of sediments (D50), sorting, and skewness. The research used the survey method while data collected were sediment-bed, bathymetry, and satellite imagery Sentinel 2A with the ebb-tide condition. Sediment was analyzed by sieve and gravimetry and interpreted as a Ternary diagram, D50, sortation, skewness, and fraction percentage spreading map. Satellite imagery Sentinel 2A was searched by the ebb-tide condition. Shorelines and delta was extracted by the Normalized Different Water Index. Bathymetry built from depth points data 2018. The results of the Ternary diagrams analysis were the Citanduy River had a sand grain size, the Pelawangan Barat Waters (PBW) were dominated by sand and the lagoon was dominated by a fine grain size and silt. The result of sediment D50, sortation, and skewness in the Citanduy River and the PBW were dominated by sand, and the lagoon was dominated by fine sediment: silt, and clay grain size. The sediment fractions were sorted very well; skewness was dominated by the fine skewed (positive skewed). The delta formation in the lagoon covers a large area, presumably due to the consolidation of the fine sediment.Keywords: Sediment Characteristics, Ebb-Tidal Delta, Western Segara Anakan Lagoon

Abstract

Selat Pantar memiliki potensi besar dalam pemanfaatan energi arus pasang surut sebagai sumber energi terbarukan. Penelitian ini bertujuan untuk menentukan lokasi optimal pemasangan turbin dengan melakukan pemodelan hidrodinamika. Pemodelan hidrodinamika dilakukan menggunakan perangkat lunak MIKE Zero, dengan memasukkan data sekunder yang meliputi pasang surut sebagai open boundary condition, data angin dari ECMWF (European Centre for Medium-Range Weather Forecasts) sebagai faktor forcing permukaan, serta data batimetri dari GEBCO (General Bathymetric Chart of the Oceans) untuk merepresentasikan kondisi kedalaman perairan. Model divalidasi menggunakan data prediksi global dari TPXO (Tidal Prediction X-bar Orography), menghasilkan RMSE sebesar 0,3158 dan koefisien korelasi 0,8059, yang menunjukkan akurasi tinggi. Hasil simulasi menunjukkan bahwa Selat Pantar memiliki pola pasang surut condong harian ganda dengan FormZahl 0,7228, serta kecepatan arus maksimum terjadi saat spring tide (0,8 m/s) dan menurun pada neap tide (Analisis dilakukan pada tiga stasiun. Stasiun 3 memiliki kecepatan arus tertinggi, sehingga direkomendasikan sebagai lokasi utama pemasangan turbin Darrieus, yang memiliki cut-in speed 0,5 m/s. Sementara itu, Stasiun 2 dapat menjadi alternatif jika optimalisasi teknologi memungkinkan operasi pada kecepatan lebih rendah. Hasil penelitian ini diharapkan dapat menjadi dasar dalam pengembangan energi arus pasang surut yang berkelanjutan di Selat Pantar.

Abstract

Kopi mangrove merupakan produk olahan mangrove yang terdiri dari kopi dan buah mangrove. Produk ini memiliki prospek pasar yang baik meskipun dihadapkan pada kendala bentuk dan cita rasa lain dari kopi umum yang ada di pasaran. Pengabdian ini bertujuan untuk meningkatkan pendapatan mitra melalui peningkatan kualitas dan pemasaran kopi mangrove. Kegiatan ini menggunakan metode eksperimental learning. Kegiatan dilakukan melalui tahap perencanaan, tahap pelaksanaan dengan membuat kopi mangrove dan melaksanakan kegiatan pelatihan digital marketing, serta tahap pendampingan dan evaluasi. Hasil kegiatan menunjukkan bahwa dari faktor cita rasa terbaik dari kopi mangrove dihasilkan dari perbandingan mangrove dan kopi sebesar 50:50% sedangkan dari faktor ekonomi sebesar 60:40%. Pemasaran digital dapat berjalan maksimal jika kualitas produk yang dipasarkan baik dan unggul. Hasil evaluasi kegiatan menunjukkan perlu adanya pelatihan pengemasan dan pengawetan produk untuk meningkatkan kualitas kopi mangrove. Kopi mangrove merupakan produk yang memiliki prospek ekonomi yang unggul sehingga optimalisasi pengolahan dan pengemasan dapat dilakukan untuk menjaga kualitas produk tersebut.
