Judul: Analisis Ekonomi Eksternalitas Kegiatan Produksi Minyak dan Gas Bumi di Laut terhadap Kegiatan Perikanan Tangkap
Abstrak: The offshore oil and gas exploitation activities have significant contribution in fulfilling the world’s oil and gas needs. However, the activities have to face several interest-conflicts with other parties such as marine capture activities that exploited different types of resources on the same location. This study shows that there is negative externality from the fishers’s perception towards the enforcement of safety zone which is located on the radius of 500 meters from the oil and gas production platform. The field study endorsed their assumption that the safety zone has limited their fishing grounds, therefore reducing their income per trip. The result shows that fishing ground’s productivity near the offshore oil and gas production platform area is lower than the productivity in non offshore oil and gas production platform area. On the contrary, the bio-economic analysis shows that the fishing ground productivity near the offshore oil and gas production platform area is higher compared to the productivity in non offshore oil and gas production platform area. The conclusion from both results is that the enforcement of safety zone in offshore oil and gas production platform area affects the marine capture’s productivity in the short run. Meanwhile the safety zone can increase and maintain the productivity in the long run because the production platform is functioning as temporary marine protected area for fish and other creatures in the sea. The findings are also utilized as input factors in designing the alternatives of environmental management model that is beneficial for both activities.

Judul: Analisis kebijakan perizinan kapal asing di zona ekonomi eksklusif Indonesia (ZEEI)
Abstrak: Masyarakat internasional telah berhasil menyusun suatu perangkat Hukum Laut yang dituang dalam bentuk naskah perjanjian yang dikenal sebagai Konvensi PBB tentang Hukum Laut 1982 (United Nations Convention on the Law of the Sea/UNCLOS). Dalam hukum tersebut diatur segala bentuk penggunaan laut serta pemanfaatan alam yang terkandung di dalamnya. Salah satunya adalah tentang Zona Ekonomi Eksklusif (ZEE). Dewasa ini marak terjadi penyimpangan dan salah satunya adalah meningkatnya kapal penangkap ikan asing yang masuk ke wilayah perairan Zona Ekonomi Eksklusif Indonesia (ZEEI). Hal ini berdampak besar pada nelayan lokal yang selanjutnya akan berakibat pada menurunnya pendapatan nelayan, menurunnya potensi sumberdaya alam dan menurunnya kontribusi terhadap negara. Berkaitan dengan hal tersebut, diperlukan aksi pemerintah untuk mencegah dan mengatasinya agar tercapai keberlanjutan sumberdaya perikanan di wilayah perairan Zona Ekonomi Eksklusif Indonesia. Mengarah pada pengaturan yang menyatakan bahwa pemanfaatan sumberdaya ikan harus dapat dilakukan secara terus menerus bagi kemakmuran rakyat, sudah semestinya bila pengelolaan dan pemanfaatannya diatur secara konsisten dan berkesinambungan sehingga mampu menjamin arah dan kelangsungan serta kelestarian pemanfaatannya. Potensi perikanan Indonesia yang melimpah perlu dikelola seoptimal mungkin dengan memperhatikan sumber perikanan itu sendiri. Untuk menghindari kemungkinan pengelolaan yang dapat menjurus ke arah kegiatan yang merugikan, perlu adanya pengawasan dan pengendalian yang didasarkan pada peraturan antara lain dalam bentuk perizinan kapal perikanan asing baik yang legal maupun yang ilegal di seluruh perairan teritorial Indonesia dan di Zona Ekonomi Eksklusif Indonesia.

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
