Valuing Ecotourism in Palutungan Resort, Gunung Ciremai National Park, Indonesia
Saputra Nur Adi,Don Koo Lee,Joowon Park,Yohan Lee 강원대학교 산림과학연구소 2016 Journal of Forest Science Vol.32 No.4
In this paper, we conducted an empirical study on the economic value of Palutungan Resort, Gunung Ciremai National Park (Indonesia), using an individual travel cost method. Gunung Ciremai is the highest mountain in West Java Province which has high biodiversity and constitutes the home range of the endangered species, Nisaetus bartelsi and leopards. Using the individual travel cost method, we estimated the annual consumer surplus of ecotourism for Palutungan Resort to be approximately $19, while its total economic value was $0.23 million. However, Palutungan Resort does not benefit exclusively, because the total economic value is divided diversely among the central government (non-tax revenue), local government (taxes), and local communities, while the transportation agencies, retailers, and gas station companies also reap some valuable benefits. In regard to the benefit allocation, all of the associated parties should participate in the conservation and preservation of natural resources in Palutungan Resort to improve the ecotourism services.

Initial Ignition Time and Calorific Value Enhancement of Briquette with Added Pine Resin
Gustan PARI,Lisna EFIYANTI,Saptadi DARMAWAN,Nur Adi SAPUTRA,Djeni HENDRA,Joseph ADAM,Alfred INKRIWANG,Rachman EFFENDI 한국목재공학회 2023 목재공학 Vol.51 No.3
The increasing demand for clean energy requires considerable effort to find alternative energy sources, such as briquettes. This research aims to develop a charcoal briquette with added pine resin (API) that has excellent combustion speed and distinctive aroma. Briquettes are composed of charcoal, pine resin (concentration: 0%–30%), and starch (up to 7%). They are produced in several stages, including coconut shell pyrolysis in conventional combustion, to obtain charcoal for the briquette precursor. Briquette compaction is conducted by mixing and densifying the charcoal, pine resin, and starch using a hydraulic press for 3 min. The hydraulic press has a total surface area and diameter of 57.7 cm2 and 3.5 cm, respectively. The briquettes are dried at different temperatures, reaching 70℃ for 24 h. The study results show that the briquettes have a thickness and diameter of up to 2 and 3.5 cm, respectively; moisture of 2.18%–2.62%; ash of 11.61%–13.98%; volatile matter of 27.15%– 51.74%; and fixed carbon content of 40.24%–59.46%. The compressive strength of the briquettes is 186–540 kg/cm2. Their calorific value is 5,338–6,120 kcal/kg, combusting at a high speed of 0.15–0.40 s. The methoxy naphthalene, phenol, benzopyrrole, and lauryl alcohol; ocimene, valencene, and cembrene are found in the API. The API briquette has several chemical compounds, such as musk ambrette, ocimene, sabinene, limonene, 1-(p-cumenyl) adamantane, butane, and propanal, which improve aroma, drug application, and fuel production. Accordingly, API briquettes have considerable potential as an alternative energy source and a health improvement product.
