Judul: Kajian Ekonomi Pelestarian Penyu Sebagai Obyek Wisata Berbasis Jasa Lingkungan (Studi Kasus Turtle Conservation and Education Center (TCEC) Pulau Serangan, Bali)
Abstrak: Turtle conservation is important activity for sustaining turtle resources. Turtle Conservation and Education Center (TCEC) in Pulau Serangan, Bali, which plays a significant role in conservation of turtle. TCEC has the potential for tourism activities, whereas the economic assessment is required for their sustainability. Research objectives of this study were to assess the turtle resource management system in TCEC, to identify the characteristics of turtle conservation in TCEC, to analyze the economic value of ecotourism in TCEC and to assess feasibility of the development of TCEC. The research method that used was survey. This research used data analysis method, that were (1) descriptive analysis, which used to assess the management system on turtle resources and to identify the characteristics of tourists, (2) Travel Cost Method (TCM), (3) Contingent Valuation Method (CVM), and (4) Cost Benefit Analysis (CBA). The result showed that were some differences in the characteristics of foreign and domestic tourists respondents viewed from age, educational background, income level, number of dependents and the frequency of their visits. TCEC has a high economic value, amounting to Rp 518.656.568.627. WTP values of domestics tourists respondents was Rp 10.661,76 per visit and the value of foreign tourists respondents was reach to Rp 55.333,33 per visit. Feasibility analysis of TCEC during 2008-2013 showed that financial sustainability of turtle conservation is limited, therefore the financial management of TCEC needs to be improved. Analysis of TCEC development plan from 2014-2023 indicated that TCEC will be feasible based on some criteria such as NPV> 0, Net B / C ≥ 1 and IRR ≥ discount rate. TCEC activities in turtle conservation is important for sustainability of turtle resource

Judul: Co-Management-Based Turtle Conservation Area Management on Pangumbahan Beach, Sukabumi, West Java
Abstrak: Penyu merupakan hewan reptil yang hidup di laut dan biasanya bertelur di kawasan pesisir serta keberadaannya telah lama terancam, baik karena faktor alam maupun faktor manusia. Penelitian ini bertujuan untuk mengidentifikasi pemangku kepentingan berdasarkan tingkat kepentingan dan pengaruh serta menganalisis konsep pengelolaan berbasis co-management terhadap pengelolaan kawasan konservasi penyu di Pantai Pangumbahan, Kabupaten Sukabumi, Jawa Barat. Penelitian ini bersifat kualitatif serta pengumpulan data dilakukan melalui wawancara mendalam (in depth-interview). Hasil penelitian menunjukkan bahwa terdapat dua belas stakeholder yang teridentifikasi berdasarkan tingkat kepentingan dan pengaruh, baik dari kelompok masyarakat maupun pemerintah. Berdasarkan analisis pengelolaan co-management, konservasi penyu di Pantai Pangumbahan memiliki tipe pengelolaan consultative yaitu adanya dialog antara pemerintah dan masyarakat serta pemerintah mulai mempertimbangkan pandangan dari masyarakat pesisir Pantai Pangumbahan. Perlu dilakukan edukasi kepada masyarakat terkait penyu dan pengelolaannya, peningkatan kapasitas pengelolaan kepada masyarakat, serta peningkatan kapasitas monitoring masyarakat dan pengembangan pola monitoring dan evaluasi partisipatif., Sea turtles are reptiles that live in the sea and usually lay eggs in coastal areas and their existence has long been threatened, both due to natural and human factors. This study aims to identify stakeholders based on the level of importance and influence and analyze the concept of co-management based on the management of sea turtle conservation areas in Pangumbahan Beach, Sukabumi Regency, West Java. This research is qualitative in nature and data collection was conducted through in-depth interviews. The results showed that twelve stakeholders were identified based on the level of importance and influence, both from the community and government. Based on the co-management analysis, sea turtle conservation in Pangumbahan Beach has a consultative management type, where there is a dialog between the government and the community and the government has begun to consider the views of the coastal community of Pangumbahan Beach. It is necessary to educate the community regarding sea turtles and their management, increase management capacity to the community, as well as increase community monitoring capacity and develop participatory monitoring and evaluation patterns.

Judul: Solid State Fermentation of Corn Hominy Using Streptomyces  sp. S2
Abstrak: Ampok merupakan hasil samping penggilingan jagung yang mengandung serat dan pati sebagai komponen utama. Selulosa yang ada dalam serat dapat didegradasi menggunakan enzim selulase yang selanjutnya dapat menghasilkan produk lebih bermanfaat seperti oligosakarida. Tujuan dari penelitian ini memanfaatkan enzim selulase yang dihasilkan Streptomyces sp. S2 dalam fermentasi padat serat ampok jagung, sehingga menghasilkan oligosakarida. Isolat Streptomyces sp. S2 menghasilkan aktivitas tertinggi di hari ke-10 (0,03 U/ml) pada uji aktivitas enzim CMCase. Pada fermentasi 48 jam, gula pereduksi dan susut bobot yang dihasilkan lebih tinggi, namun total gula dan derajat polimerisasi yang dihasilkan lebih rendah dibandingkan fermentasi pada waktu 24 jam. Hal ini menandakan bahwa kerja enzim selulase dalam mendegradasi serat ampok meningkat dengan semakin lamanya waktu fermentasi. Produk yang dihasilkan dari fermentasi padat yaitu oligosakarida dengan derajat polimerisasi 4,68 pada fermentasi 24 jam dan 2,10 pada fermentasi 48 jam., Hominy feed is a by-product of the corn dry milling process which contains fiber and starch as the main components. Cellulose in fiber can be degraded using cellulase enzymes which will produce more useful products such as oligosaccharides. The objective of this research was to apply the cellulase enzyme produced from Streptomyces sp. S2 in the solid-state fermentation of hominy fiber, thus producing oligosaccharides. Streptomyces sp. S2 produced the highest activity on day 10 (0.03 U/ml) in the CMCase enzyme activity test. Reducing sugar and weight loss were higher at 48 hours fermentation than 24 hours fermentation, while the total sugar and polymerization of degree were lower at 48 hours fermentation compared to 24 hours fermentation. This indicates that the action of the cellulase enzyme in degrading hominy fiber increases with the longer fermentation time. The product of solid fermentation are oligosaccharides with degree of polymerization are 4,68 at 24 hours fermentation and 2,10 at 48 hours fermentation.
