Mrica Reservoir located in Banjarnegara Regency is amultipurpose reservoir. Based on the report of PT Indonesia Power UnitPembangkitan (UP) Mrica in 2016, the sediment of Mrica Reservoir hasentered the critical phase as it reached 114.25 million m3 and the value ofland-cover index of Mrica reservoir was 80% of the total watershed areawith the average sedimentation rate reaching 4.09 million m3 per year. Itis estimated that the reservoir will be full of sediment by 2021. The maincause of the high rate of sedimentation in Mrica reservoir is the changes inland use and agricultural-plantation activities in the upper river areas andalong the river flow of Serayu River, Merawu River, and Lumajang River. This study aimed to determine the appropriate type of conservation forMrica Reservoir. The method used was the Analytical Hierarchy Process(AHP), in which the determination of conservation efforts was based onsecondary data and observation. According to the current condition ofMrica Reservoir, the planned conservation efforts include two types, namely non-structural conservation and structural conservation. If theconservation begins in 2019, the total sediment in 2021 will decrease to74% and it is predicted that the sediment will be exhausted by 2056.

The background of the problems in this study is the decreasing quality of Sade hamlet amid rising tourist arrivals. From the environmental aspect, the conditions of the hamlet began to decline, in which the initial pattern of Sade has started a lot of changes towards the deficient and began to leave the local tradition. One effort to improve the condition of Sade hamlet in social, cultural and the environmental aspect is through the formulation of a sustainable structuring, the presence and identity maintaining and making a sustainable Tourism Village. Through analysis of AHP (Analytical Hierarchy Process) by collecting the perceptions of some experts through interviews and questionnaires, obtained by weighting the priority of the experts, namely the preservation of culture as an element of priority-level goals to be achieved in the development of Sade Hamlet as a tourist village at 0,476. While the determination of the level of the main criteria in the achievement of these objectives is the highest weight while maintaining a typical village environment at 0.319. Priority strategies that get the highest weight of the experts is that Sade Hamlet Revitalization with a priority weighting of 0.583. The second priority is the relocation of Hamlet at 0.235. Lowest weighting or last priority is Replication Sade Hamlet at 0.182.

Hasil survei potensi yang dilakukan IUCN dan LPSPL Sorong menunjukkan nilai kelimpahan ikan napoleon (Cheilinus undulatus) di Kabupaten Raja Ampat termasuk dalam kategori rendah. Walaupun demikian, nelayan tetap menginginkan ada kuota untuk pemanfaatannya karena merupakan salah satu sumber mata pencaharian utama. Aktivitas pemanfaatan harus disertai dengan upaya pengendalian untuk menjaga kelestarian sumberdaya. Penerapan upaya fishing control dan manajemen kebijakan belum dilakukan secara optimal, sehingga diperlukan penetapan berdasarkan skala prioritas. Tujuan penelitian ini adalah untuk mengidentifikasi kondisi pemanfaatan dan menentukan skala prioritas upaya untuk mengendalikan pemanfaatan ikan napoleon di Kabupaten Raja Ampat. Penentuan skala prioritas dianalisis dengan model Analytical Hierarchy Process (AHP) dengan melibatkan pakar di bidang konservasi dalam penilaian. Berdasarkan hasil identifikasi, kondisi pemanfaatan ikan napoleon di Kabupaten Raja Ampat dilakukan belum sesuai dengan ketentuan regulasi yang telah ditetapkan. Hasil penilaian dengan model AHP menunjukkan bahwa kriteria yang paling penting untuk mengendalikan pemanfaatan ikan napoleon adalah sumberdaya ikan lestari, dan urutan prioritas alternatif adalah sosialisasi kepada nelayan/pengusaha (bobot 0,2935), pengawasan (bobot 0,2715), survei kelimpahan secara berkala (bobot 0,2181) dan penerapan lalu lintas perdagangan melalui bandara (bobot 0,2169).The results of potential survey by IUCN and LPSPL Sorong showed the abundance value of napoleon fish (Cheilinus undulatus) in Raja Ampat Regency was low category. Nonetheless, the fisher quota for its utilization because it is one of the main sources of livelihood. The utilization activities should be followed by control of effort to maintain resource sustainability. Implementation of fishing control and management decisions has not been done optimally, therefore it need to be set based on priority scale. The purpose of this study were to identify conditions of utilization and to determine the priority scale to control utilization of napoleon wrasse fishery in Raja Ampat Regency. Determination of priority scale were analyzed with Analytical Hierarchy Process (AHP) model by involving experts in the field of conservation in the assessment. Based on the results of identification, the condition of the utilization of napoleon fish in Raja Ampat Regency was not with the regulation. The results of the assessment with AHP model showed that the most important criteria to control utilization of napoleon wrasse fishery is sustainable fish resources, and alternatives priority order are socialization/awareness program to fishers/live fish buyer (value 0.2935), surveillance (value 0.2715), periodic density surveys (value 0.2181) and implementation of trade air-only (value 0.2169).

Abstract In the fast-changing internet era, private sale websites attracted an enormous interest from the consumers in especially online marketing of apparel goods. The retailers may garner more benefit if the prior issues for the consumers when they are purchasing apparel products online is known. Reviewing the literature, this study presents the factors in three groups in a hierarchical manner considering the multidimensional aspect of online purchasing of apparel products from private sale websites and then determines the prior issues for the consumers by making pairwise comparisons among these factors using analytical hierarchy process on a sample group of 100 Turkish respondents. The findings revealed that “privacy/security” in terms of online shopping criteria, “product information” in terms of apparel products criteria, and “discount ratio” in terms of private shopping criteria took highest scores of importance when the aspects were analyzed individually. Nonetheless, the parameters regarding the online shopping criteria were found to be more important than the criteria regarding the apparel products and private shopping criteria. In the end, it was also observed that these items that were found to have highest importance were actually corresponding to the risks of the situation.

In order to leave a livable world to future generations, the elimination of environmental pollution, which is one of the important dimensions of sustainability, increases its importance every day. Undoubtedly, among the factors that cause environmental pollution, the role of ships is quite high. The seas are also polluted by the routine operation of ships as well as marine accidents. Pollution arising from the routine operations of ships is caused by the discharge of pollutants such as ballast water, bilge water, sludge or garbage into the sea. In addition, emissions from ships and oil and fuel pollution caused by the routine operation of ships also play an important role in environmental pollution. In this study, the phenomena resulting from the routine operations of ships and causing environmental pollution were examined using the Analytical Hierarchy Process (AHP) method, which is one of the multi-criteria decision-making methods, and the perceptions of ship operators towards environmental pollution were tried to be determined.
