Judul: Economic Benefit Analysis of Fishery Resource at Marine Protected Area of Karimunjawa National Park.
Abstrak: Marine ecosytem has many benefits that provide an important economic justification for establishing Marine Protected Area (MPA), but these are often not fully understood by local community surrounding and stakeholders. This research was aimed to distinguish whether the establishment of Taman Nasional Karimunjawa (TNKj) as a MPA has contributed economic benefits of fishery resource to the local community as well as the regional economy. The change of benefit or loss rate was calculated using productivity approach of Economic Valuation Method and an iconic simulation. Location Quotient (LQ) analysis was applied to see the contribution of fishery sub sector to regional economic of Jepara. To know the perception of fishermen, Descriptive method was used. The Result showed that at present the economic benefit of fishery wasn’t quite significant, this probably corresponded to the increase of destructive fishing activities prior to the establishment of TNKj in 1999. The contribution of fishery sub-sector to Gross Domestic Product (GDP) of Jepara in 1999-2004 declined. However the datas indicated that the benefit would be obtained in afew years, as sea environment degradation declined and conservation management became more effective. As MPA, sustainable aspect is the most important thing, therefore the economic development should be in line with the ecology. It needs good management and coordination among all stakeholders as well as wider involvement of local community. The concept of collaborative management is proper to examine for advanced research.

Judul: Social economics analysis of benefit marine protected area in Kepulauan Seribu, DKI Jakarta
Abstrak: This research is aimed to determine weather there are social and economic benefits that can be derived from marine protected area of Taman Nasional Laut Kepulauan Seribu. Especially this study was aimed to determine the social and economic consequence of establishment of MPA in Kepulauan Seribu. The study was time series analysis to asses tren of supporting facilities in Taman Nasional Laut. Result from this time series were then used to asses sustainability status of TNKL by means of Marine Protected Area Evaluation Model (MPAEM). A multicriteria analysis was used to evaluate socio-economic perceptions of people living at TNKL. Finally an economic valuation technique was employed to asses the monetary benefits or losses associated with the establishment of MPA.

Judul: Sintesis dan pengukuran konduktivitas listrik, sifat termal, serta struktur konduktor superionik gelas AgBr-Ag2O-B2O3
Abstrak: Koncluktor superionik adalah padatan ionik yang mempunyai koncluktivitas listrik tinggi yaitu lebih besar dari 10-4 .0·1 cnf1, tetapi biasanya terjadi pada suhu yang tinggi. Pcneli:ian ini berlujuan untuk mensintesis clan memperoleh bahan konduktor superionik yang berbasis gelas (AgBr)., (Ag20-B20_1)1_, pacla suhu kamar, serta karakterisasi konduktivitas listrik, sifat tcrrnal dan perubahan stmktur dari sistem gclas terscbut. Konduktor superionik berbasis gclas (AgBr)x (Ag2O-B2O3)1.x dcngan x yang bcrvariasi yaitu 0,5; 0,7; dan 0,8 tclah disintcsis dcngan menggunakan teknik pendinginan ccpat. Carnpuran lcbunu1 AgBr dan Ag20-B203 didinginkan secara cepat dalam lingkungan nitrogen cair sehingga terbentuk (AgBrt (Ag20-B203)1_,. Pcngukuran konduktivilas listrik dilakukan pada berbagai komposisi x dcngan earn mcngukur tahanan listriknya dengan suhu yang bervariasi menggunakan mctoda ac yang mcnerapkan: prinsip jembatan Wheatstone. Untuk menganalisis sifat struktur digunakan difrnksi sinar-x, sedangkan pengukuran sifat tennal dari konduktor digunakan Differential 7'lierma/ Analysis. Hasil pengukuran mcnunjukkan bahwa konduktivitas listrik scnyawa (AgBr), (Ag20-B203)1• , naik dcngan pcnambahan garam AgBr pada sistem gelas Ag2O-B2O3 mcncapai nilai konduktivitas yang maksimum kcmudian nilai tcrsebut akan l\mm kemba!L Konduktivitas listrik yang optimum didapat pada komposisi x = 0,8, yaitu 9,12 · 10-6 n·1 cm-1 pada suhu kamar. Oleh sebab itu scnyawa (AgBr), (Ag20- B203)1.x bclum dapat digolongkan sebagai konduktor supcrionik pada suhu kamar. Namun scnymva tcrscbut dapat bcrlaku scbagai konduktor superionik jika suhu dinaikkan hingga 110°C dcngari konduktivitasnya 1,22 · 10··1 rr1 cnf1• Hasil analisis tcnnal untuk semua komposisi menunjukkan suhu transisi gelas sekitar l 75°C, scdangkan pola difraksi yang tcrjadi pada x = 0,5 dan x = 0,8 adalah kristalin, dan pada x = 0,7 rnempunyai polu amorf.
