Abstract

Tujuan penelitian ini adalah untuk menentukan stok karbon ekosistem mangrove Pasir Putih Pulau Bawean. Metode yang dilakukan adalah sampling semi destruktif, dilakukan pada 100 plot dengan ukuran 10 x 10 meter. Pada setiap plot dilakukan identifikasi dan pencatatan jumlah individu, pengambilan sampel ranting, pengukuran keliling batang, tinggi batang untuk menentukan biomassa dan stok karbon mangrove. Hasil perhitungan stok karbon menunjukkan bahwa jenis Sonneratia alba memiliki stok karbon tertinggi yaitu 109.755,79 ton C/ha, sedangkan Rhizophora apiculata memiliki stok karbon paling kecil yaitu 1.364,84 ton C/ha. Perbedaan nilai stok karbon dipengaruhi oleh umur pohon, diameter pohon, berat jenis, dan jumlah pohon. Hasil perhitungan terhadap nilai total stok karbon menunjukkan bahwa mangrove berkontribusi terhadap penurunan emisi karbon sebesar 196.841,16 ton C/ha. Jadi total stok karbon yang tersimpan di ekosistem mangrove Pasir Putih Pulau Bawean Desa Sukaoneng  Sukaoneng  Kecamatan  Tambak Kabupaten Gresik, Jawa Timur adalah 196.841,16 ton C/ha.

Abstract

Pepper plant development requires data and information on land potential and land suitability class assessment based on the physical and chemical properties criteria so that the land can be productive. The study aimed to determine the land suitability class for pepper plants in Bireuen Regency. The research was conducted in Bireuen Regency. The unit land map (Satuan Peta Lahan, SPL) resulting from the overlay of the slope map, land use map, and soil type map was used in this study. The method used is a survey method with a land unit approach consisting of four stages: (1) preparation stage, (2) preliminary survey, (3) main survey, and (4) presentation of results. The results showed that the land had good to poor drainage, soil depth >75 cm, flat to steep slopes, mild to very heavy erosion hazard, dusty clay texture, low to high cation exchange capacity (CEC), slightly acidic to slightly alkaline pH, low organic C, Base Saturation (BS) is low to high, N total is low to very low, P2O5 is very low, and K2O is very low. Land suitability class for pepper plants in Bireuen Regency includes marginal suitability (S3) with limiting factors in the form of drainage, texture, CEC, BS, N-total, P2O5, K2O, slope, and erosion hazard. Improvements include making rorak, planting contours, drainage systems, applying manure or compost, and planting cover crops.
