Judul: Perancangan Model Social Enterprise Ekowisata Perairan di Kawasan Waduk Jatigede Sumedang, Jawa Barat
Abstrak: Terdapat beberapa tempat wisata di kawasan Waduk Jatigede yang sudah beroperasi, tetapi belum mencerminkan potensi dan realitas waduk, yaitu konsep wisata perairan. Hal tersebut menjadi peluang untuk dikembangkannya ekowisata perairan berbasis social enterprise sebagai upaya untuk mengatasi kegagalan pasar dan kegagalan pemerintah. Penelitian ini bertujuan untuk merancang model social enterprise ekowisata perairan di kawasan Waduk Jatigede. Potensi ekowisata perairan dianalisis secara deskriptif, aspirasi pemangku kepentingan dianalisis menggunakan analisis SOAR (Strengths, Opportunities, Aspirations, Results) dan metode AHP (Analytical Hierarchy Process), serta model social enterprise dirancang menggunakan panduan yang dimodifikasi dari Anderson (2020) dan model yang dipublikasikan oleh Lontoh (2021). Adapun sampel didapatkan dari lima responden yang memiliki wewenang dan pengetahuan terkait objek penelitian. Penelitian ini menghasilkan social impact investment social enterprise models. Model social enterprise tersebut dapat menyeimbangkan antara pelaksanaan misi sosial dan aktivitas bisnis ekowisata perairan di kawasan Waduk Jatigede. Temuan ini dapat dijadikan acuan dalam mengembangkan ekowisata perairan berbasis social enterprise di Indonesia., Numerous tourist attractions in the surrounding Jatigede Reservoir area are already in operation, but it has not reflected their full potential as aquatic theme tourism. Moreover, it could become an opportunity to develop the social enterprise to overcome market failures and government failures. This research aims to design a social enterprise model of aquatic ecotourism in the Jatigede Reservoir area. First, the potential of aquatic ecotourism is analyzed descriptively. Then the stakeholder aspirations are analyzed using SOAR (Strengths, Opportunities, Aspirations, Results) analysis and AHP (Analytical Hierarchy Process) methods. Finally, the suitable social enterprise model is designed using the modified Anderson 2020 framework and a model published by Lontoh (2021). The sample was obtained from five respondents who had authority and knowledge related to the research object. This study resulted in the social impact investment social enterprise models.

Penelitian ini bertujuan menilai potensi sumberdaya situ untuk ekowisata perairan di Situ Rawa Besar, Kota Depok untuk pengembangan yang berkelanjutan. Metode yang digunakan untuk penelitian ialah analisis indeks kesesuaian wisata, daya dukung kawasan, analisis perumusan strategi pengelolaan dan pengembangan ekowisata memakai analisis Strength Weakness Opportunity Threat (SWOT), dan menghitung nilai ekonomi langsung dari kegiatannya berdasarkan daya dukung kawasan. Hasil penelitian menunjukkan bahwa kegiatan ekowisata perairan seperti perahu, duduk santai dan memancing dapat dilakukan dengan nilai sesuai. Masing-masing kegiatan dilakukan dengan daya tampung masing-masing secara berurutan yaitu 248 orang per hari, 58 orang per hari, dan 11 orang per harinya. Luasan daerah kegiatan wisata yang dapat digunakan untuk perahu seluas 117.654 m2, kegiatan duduk santai dapat menggunakan lintasan sepanjang 580 m, dan kegiatan memancing dapat menggunakan 13.287 m2. Total nilai ekonomi langsung pada kegiatan wisata Situ Rawa Besar sebesar Rp.1.243.704.000. Situ Rawa Besar has a body of water with a natural attraction in an urban area. Natural attractions is a priority to not reduce visitors who will go to Situ Rawa Besar. This study aims to assess the potential of aquatic ecotourism in Situ Rawa Besar, Depok City for sustainable development.

Judul: Prenilasi Senyawa β-Diketon sebagai Prekursor 3-Prenilflavon
Abstrak: One group of flavonoids that has not been commonly synthesized is 3- prenylflavone. The main objective of this experiment was to synthesize precursor of 3-prenylflavone. Firstly, β-diketone was synthesized via 4 steps from phenol as starting compound with total yield of 24%. Prenylation of β-diketone with prenyl bromide and K2CO3 base produced 4 fractions which were separated by using preparative thin layer chromatography (PTLC) with n-hexane:EtOAc (8:2) as the eluent. Fraction with Rf = 0.80 was further separated by using preparative PTLC with n-hexane:EtOAc (99:1) as the eluent. Two fractions were obtained with Rf = 0.38 and 0.42. The first fraction has been characterized as diprenylated β-diketone with 49% yield. Application of protecting group on the phenolic OH group in β- diketone are needed to obtain monoprenylated β-diketone which can be further cyclized into 3-prenylflavone
