Abstract

Ekosistem mangrove memiliki peran strategis dalam menjaga stabilitas wilayah pesisir, baik dari aspek ekologis, ekonomis, maupun sosial. Meningkatnya aktivitas antropogenik seperti permukiman, pariwisata, dan perikanan menyebabkan akumulasi sampah laut yang mengancam keberlanjutan ekosistem mangrove. Kepulauan Karimunjawa sebagai kawasan konservasi mengalami tekanan akibat polusi sampah laut yang terperangkap di sistem perakaran mangrove. Penelitian ini bertujuan untuk mengidentifikasi jenis dan komposisi sampah laut, menghitung kepadatan, serta memetakan distribusi spasialnya pada ekosistem mangrove. Penelitian dilakukan pada dua lokasi dengan karakteristik yang berbeda, menggunakan metode line transect berdasarkan zonasi pertumbuhan mangrove (seaward, middle, dan landward). Pengolahan data mencakup uji independent samples t-test, regresi polinomial, serta analisis spasial menggunakan citra satelit Sentinel-2A. Hasil Penelitian menunjukkan sampah plastik merupakan jenis dominan (65,86%), diikuti oleh styrofoam (20%) dan karet (9,81%). Lokasi mangrove dekat permukiman memiliki kepadatan sampah yang signifikan lebih tinggi dibandingkan kawasan wisata (p < 0,05). Sampah laut terkonsentrasi pada zona seaward (92,88%) dan menunjukkan hubungan kuat dengan jarak pengambilan sampel dari pantai (R² = 0,83). Vegetasi mangrove yang ditemukan di lokasi penelitian terdiri atas Rhizophora sp., Sonneratia sp., Ceriops sp., dan Lumnitzera sp. yang memiliki karakteristik perakaran berbeda dan berperan dalam proses penjebakan sampah. Penelitian ini memberikan kontribusi dalam penyusunan strategi mitigasi berbasis spasial untuk perlindungan ekosistem mangrove dari tekanan limbah padat.

Abstract

Cengklik Reservoir is a reservoir that has many benefits for the surrounding community such as irrigation and aquaculture, namely Floating Net Cages. FNC in these waters can have an impact on the remaining feed produced in cultivation. The rest of the feed can cause increased nutrient concentrations and eutrophication in the waters. These impacts can affect water quality conditions, phytoplankton abundance and primary productivity. The purpose of this study was to determine the primary productivity, abundance of phytoplankton, nitrate (NO3) and orthophosphate (PO4) in Cengklik Reservoir, Boyolali. The study was conducted in March 2023. The sampling point determination method uses Stratified Random Sampling with four stations in two repeats. Data processing using simple and multiple linear regression analysis with Jamovi application. The results obtained gross primary productivity value is 62.50 - 156.25 mgC/m3/hour while net primary productivity is 31.25 - 93.75 mgC/m3/hour. The abundance of phytoplankton results the most in the Cyanophyceae class with a percentage of 50.72% - 65.06%. The relationship between phytoplankton abundance and gross primary productivity is obtained R2 = 0.142 while net primary productivity R2 = 0.608 which means that the relationship of phytoplankton abundance affects the production of net primary productivity in waters. The relationship between nitrate and phosphate analysis with phytoplankton abundance in waters R2 = 0.311 which means that nitrate and orthophosphate have a low influence on phytoplankton abundance. The abundance of phytoplankton in waters can be influenced by other factors.Keywords: Cyanophyceae; Nitrate; Orthofosfat; Phytoplankton

Abstract

Pantai Ngobaran di Gunungkidul memiliki potensi wisata melalui keberadaan Pura dan Arca, namun tingkat kunjungan masih rendah akibat penataan ruang publik yang belum optimal. Pengembangan berbasis daya dukung diperlukan untuk mendorong peningkatan kunjungan dan keberlanjutan destinasi. Tujuan penelitian ini untuk menganalisis daya dukung kawasan, persepsi masyarakat lokal, dan nilai ekonomi wisata Pantai Ngobaran. Penelitian ini menggunakan pendekatan kuantitatif. Penelitian dilaksanakan pada bulan Februari 2024 dengan metode survei dengan memberikan kuesioner kepada responden yang terdiri dari masyarakat lokal sebanyak 30 orang dan wisatawan sebanyak 100 orang. Teknik pengambilan sampel yang digunakan adalah snowball sampling untuk masyarakat lokal dan accidental sampling untuk wisatawan. Analisis data menggunakan perhitungan daya dukung kawasan (DDK), interval skor, dan willingness to pay (WTP). Hasil penelitian menunjukkan nilai DDK adalah 3.021 orang/hari dan nilai DDP adalah 302 orang/hari sehingga dalam setahun setara dengan 110.230 orang/tahun. Jumlah wisatawan Pantai Ngobaran pada tahun 2023 yaitu 67.960 orang/tahun yang berarti jumlah wisatawan tersebut belum melebihi daya dukung kawasannya. Hasil persepsi masyarakat lokal berdasarkan penerimaan masyarakat, berupa pengaruh wisatawan terhadap pola/gaya hidup masyarakat dan interaksi wisatawan dengan masyarakat, serta dukungan masyarakat tergolong baik. Nilai total WTP wisatawan sebesar Rp579.019.200/tahun dengan rata-rata nilai WTP individu adalah Rp8520/orang.TITLE: ANALYSIS OF CARRYING CAPACITY AND ECONOMIC VALUE FOR THE TOURISM DEVELOPMENT OF NGOBARAN BEACH IN YOGYAKARTANgobaran Beach in Gunungkidul possesses notable tourism potential due to its distinctive cultural features, including a Pura and Arca. However, suboptimal public space management has contributed to relatively low visitor numbers. This study aims to assess the area’s carrying capacity, evaluate local community perceptions, and estimate the economic value of tourism through tourists’ willingness to pay (WTP). A quantitative approach was employed, with data collected in February 2024 through structured questionnaires distributed to 30 local residents (via snowball sampling) and 100 tourists (via accidental sampling). Analysis included carrying capacity (CC) calculations, interval scoring, and WTP estimation. Findings indicate that the physical carrying capacity is 3,021 visitors/day, while the real carrying capacity is 302 visitors/day, equivalent to 110,230 visitors/year. The 2023 tourist volume (67,960/year) remained within these limits. Community perceptions were generally positive, particularly regarding lifestyle adaptation and tourist interaction. The total WTP value was estimated at IDR 579,019,200/year, with an average of IDR 8,520/ person. These results underscore the need for capacity-based development strategies to enhance both visitor numbers and sustainability outcomes at the site.
