Taman Margasatwa Ragunan merupakan salah satu kebun binatang terbesar di Indonesia dan terbesar se-Asia Tenggara. Tidak hanya sebagai tempat rekreasi yang aman, dekat, serta biaya yang murah namun Taman Margasatwa Ragunan juga mengandung keanekaragaman hayati yang memiliki nilai konservasi tinggi. Maka dari itu, penelitian ini ingin melihat nilai ekonomi Taman Margasatwa Ragunan berdasarkan pendekatan travel cost method dan choice modeling. Dalam metode travel cost dengan menggunakan OLS (Ordinary Least Sqaure), variabel biaya perjalanan dan status pernikahan signifikan mempengaruhi jumlah kunjungan. Total nilai manfaat yang diperoleh sebesar Rp. 186.002.217.815,00 per periode atau sebesar Rp. 36.068,00 per kunjungan. Untuk choice modeling menggunakan atribut spesies hewan, toilet, kebersihan, dan tiket masuk. Analisa dengan menggunakan Conditional Logit menunjukkan total compensating surplus paling tinggi pada skenario tiga dengan total nilai manfaat Rp. 16.886,29 atau sebesar Rp. 87.080.925.787,00.

Ragunan Zoo is one of the largest zoos in Indonesia and the largest in Southeast Asia. Not only as a place of recreation that is safe, close and low cost, but Ragunan Zoo also contains high biodiversity value. Therefore, this study wants to estimate economic value Ragunan Zoo through travel cost method and choice modeling approach. In travel cost method using OLS (Ordinary Least Sqaure), cost of travel and marital status significantly affect the number of visits. The total value of the benefits gained is Rp. 186.002.217.815,00 per period or Rp. 36.068,00 per visit. Choice modeling?s attributes are animal species, toilets, cleanliness and cost. Conditional logit shows that respondents are willing to pay from Rp. 10,000 to Rp. 15,000 for improvement services for Ragunan Zoo. Using Conditional Logit, the results showed that the highest total compensating surplus on third scenario with total value of Rp. 16.886,29 or Rp. 87.080.925.787,00 per period.

[ABSTRAK
Pertumbuhan penduduk, pertumbuhan ekonomi dan urbanisasi di kota- kota besar di negara berkembang seperti Jakarta menyebabkan timbulan/generasi sampah semakin meningkat. Sementara itu kapasitas TPA semakin menurun. Untuk mengatasi permasalahan tersebut diperlukan upaya pengurangan sampah sejak dari sumbernya. TPS 3R dapat mengurangi volume sampah yang diangkut dan dibuang ke TPA melalui pengomposan dan daur ulang pada skala kawasan. Namun demikian TPS 3R sangat mengandalkan peran serta masyarakat dalam bentuk retribusi sampah dan pemilahan sampah sejak dari sumbernya. Metode Choice Modeling (CM) dan Contingent Valuation (CV) digunakan untuk mengetahui WTP masyarakat atas beragam pilihan layanan sampah berbasis 3R. CM digunakan untuk mengestimasi harga implisit tiap atribut layanan seperti aroma TPS, pemilahan dan frekuensi pengumpulan sampah. Hasil CM menunjukkan pemilahan sampah dari sumber masih merupakan beban bagi rumah tangga sedangkan aroma TPS yang semakin tidak bau dan pemilahan sampah di TPS menambah utilitas rumah tangga. Secara keseluruhan rumah tangga ternyata memberikan penilaian yang cukup tinggi pada layanan manajemen sampah berbasis 3R. Dengan membandingkan potensi pendapatan dengan biaya layanan manajemen sampah tiap skenario, ditemukan bahwa tingkat cost recovery layanan manajemen sampah ramah lingkungan/TPS 3R lebih tinggi dibandingkan layanan konvensional. Dengan adanya tingkat cost recovery yang lebih tinggi dan sejumlah eksternalitas positif yang dapat diperoleh, tidak ada alasan bagi pemda untuk tidak mendukung layanan manajemen sampah berbasis 3R.

ABSTRACT
Population,economic growth and urbanization in big cities in developing countries like Jakarta cause proliferating growth in solid waste generation. Meanwhile landfill capacity is diminishing. To overcome this problem, efforts to reduce waste from the source are needed. Solid waste intermediate treatment facilities based on 3R principles (TPS 3R) can reduce waste which must be transported and disposed through communal composting and recycling. However TPS 3R relies on community participation in the form of waste retribution and at-source-wastesorting. Choice Modelling (CM) and Contingent Valuation (CV) are used to elicit consumers? willingness to pay (WTP) for different service options. The CM especially aims to estimate the implicit price for each service attribute such as the TPS odour, at source waste sorting and collection frequency. CM results indicate at-source-waste-sorting is still a burden for households while the diminishing bad odour and waste sorting in TPS add household utilities. Overall household turned out to give a fairly high valuation on 3R-based solid waste management services. By comparing the potential service fee revenue with its operational cost in each scenario, it was found that the cost recovery rate of ecological solid waste management service/TPS 3R is higher than the conventional one. With higher cost recovery rate and a number of positive externalities that can be obtained, there is no reason for the government not to support 3R-based solid waste management service/TPS 3R.;Population,economic growth and urbanization in big cities in developing countries like Jakarta cause proliferating growth in solid waste generation.
