Abstract

Ecosystem services for food and water supply are important to support regional economic  development. The purpose of this research were to analyze the ability of ecosystems to provide food and water and its distribution spatially in North Kolaka District. This research was conducted through a study of ecoregion characteristics, including landscape characteristics, natural vegetation types and land cover. In addition, population data, water availability, food availability and administrative data in North Kolaka were collected. Data analysis includes the calculation of ecosystem service indexes, spatial distribution of ecosystem service indices and indicative status of the carrying capacity of food and water. The results showed that the average index of environmental services for food supply in North Kolaka District was 3.26 with a moderate category, while the index of environmental services for water supply was 2.77 with also a moderate category. Food service ecosystem service index in the medium category dominated North Kolaka District with an area of 214,119.36 hectares (72.96%) and a high category of 67,393.22 hectares (22.96%). The ecosystem services index of water supply is low and medium with an area of 58,429.52 hectares (19.91%) and 225,918.15 hectares (76.98%). The overall carrying capacity of food and water in North Kolaka District is still a surplus. The area of the food surplus reaches an area of 218,056.15 hectares (74.30%) and the total food surplus is 45,915,960,670 kcal. The area of water surplus in North Kolaka District is 230,914.85 hectares (78.68%) with a total surplus of 1,235,849,200 m3/year.Keywords: carrying capacity, ecoregion, ecosystem service index , spatial distribution

Abstract

ABSTRAKTahura Nipa-Nipa merupakan salah satu kawasan konservasi di Sulawesi Tenggara yang ditetapkan melalui SK Menteri Kehutanan No.103/Kpts-II/1999 seluas 7.877,5 ha. Tahura Nipa-Nipa memiliki potensi flora dan fauna yang sangat beragam salah satunya adalah jenis Pooti (Hopea gregaria). H. Gregaria adalah jenis pohon dari family Dipterocarpaceae yang berukuran sedang dan mencapai tinggi 35 m. H. gregaria memiliki penyebaran yang terbatas dan hanya ditemukan di Sulawesi Tenggara dan khususnya di Tahura Nipa-Nipa. H. gregaria juga dilaporkan sebagai jenis tumbuhan yang terancam punah. Penelitian ini bertujuan untuk mengetahui tingkat kerapatan dan pola penyebaran H. gregaria di sekitar sungai Lahundape Tahura Nipa-Nipa Kendari. Metode yang digunakan dalam penelitian ini adalah metode kombinasi jalur berpetak yang diletakan secara purposive sampling. Hasil penelitian menunjukan bahwa jumlah individu H. gregaria 57 individu pada tingkat pohon, 96 individu tingkat tiang, 72 individu tingkat pancang dan 106 individu tingkat semai, dengan nilai kerapatan H. gregaria pada tingkat pohon 67,86 individu/ha, tingkat tiang 457,14 individu/ha, tingkat pancang 1.371,76 individu/ha dan 50.476,19 individu/ha. Pola penyebaran tumbuhan H. gregaria di sekitar Sungai Lahundape tersebar secara acak dengan nilai indeks morisita pada setiap tingkatan pertumbuhan < 1. Kata Kunci : Kerapatan dan sebaran Tegakan, Pooti, Tahura Nipa-Nipa
