Judul: Penataan Situ dalam rangka Pengembangan Wisata Tirta Berbasis Konservasi: Studi Kasus Situ Kemuning, Kabupaten Bogor
Abstrak: Kemuning lake located in Kabupaten Bogor known has a function as a reservoir of water that control flood and provide recreation. The condition of Kemuning lake declines due to silting up and shrinkage caused by anthropogenic activities. Kemuning lake as a water resource infrastructure is facing threats, and potential efforts are required to manage it for its preservation and also for the benefit the surrounding community. The aims of this study was to identify the physical condition to support conservation of the water resource in Kemuning lake and to analyze of water tourism development in the lake through the potential space utilization. The case study research method was done with the approach to assess the physical condition of lake, carrying capacity of tourism, potential spatial analysis and strategy formulation. The results showed that the physical condition of Kemuning lake is currently disturbed. It mainly caused by silting and shrinkage or encroachment. The percentage of shrinkage of water is more than 25%. Eventhough the lake has been disturbed but it still has a good potential to support tourism. Extensive spatial analysis showed that 34.35% (5.27 ha) of area have a potential to support tourism. Space was divided into two sections, namely; green open space and tourist services space. Carrying capacity analysis found that the lake has a carrying capacity to support fishing (202 person/day), relaxing and jogging (1698 person/day) and water attraction activity (142 person/day). The implementation of tourism development has to be integrated with impact management in order to support sustainability. There are two main strategy for developing management of Kemuning lake through water tourism approach, e.g. 1) revitalization and restructuring of the potential space utilization as integrated approach, 2) Socialization of the community through empowerment and environmental education in schools. Furthermore, the problem solving of Kemuning lake for sustainable management requires lake revitalization and restructuring of potential space utilization as action plan, and empowering local communities to encourage sense of ownership.

Judul: Redesign of Situ Gede Landscape as a Nature Park
Abstrak: Situ merupakan salah satu sumber daya perairan yang memberikan manfaat bagi kehidupan manusia baik dari segi ekonomi maupun lingkungan. Situ Gede, salah satu danau yang terdapat di Kota Bogor. Tujuan penelitian ini adalah mengidentifikasi dan menganalisis potensi lanskap Situ Gede dan membuat rekomendasi desain lanskap Situ Gede sebagai kawasan wisata alam. Penelitian ini mengacu pada proses perancangan Simonds (2006) dengan modifikasi penggabungan tahap akhir, yaitu tahap construction dan operation menjadi tahap proses desain. Potensi Situ Gede yaitu akses mudah dan memiliki kesan ruang terbuka hijau dan dikelilingi banyak pepohonan yang dapat menyediakan udara segar. Kendalanya adalah lahan parkir yang terbatas dan kurangnya fasilitas yang layak untuk digunakan serta sampah yang menumpuk di tepi danau. Lahan di kawasan Situ Gede potensial sebagai kawasan wisata alam. Jenis kegiatan yang diinginkan responden adalah berkemah, bersampan keliling situ dan bersepeda, kegiatan tersebut dapat dilakukan dengan menyediakan lahan khusus berkemah, memperbaiki fasilitas perahu dan menyediakan jalur untuk bersepeda. Konsep dasar yang akan diaplikasikan pada kawasan wisata danau Situ Gede adalah ekowisata dengan konsep desain, pola organik dan bentuk kujang. Hasil dari penelitian dibatasi hingga produk akhir berupa site plan, gambar potongan, gambar detail, dan ilustrasi., Situ is one of the water resources that provide benefits for human life both in terms of economy and the environment. Situ Gede, one of the lakes in the city of Bogor. The purpose of this study is to identify and analyze the potential of the Situ Gede landscape and make recommendations for the design of the Situ Gede landscape as a natural tourist area. This study refers to the design process of Simonds (2006) with the modification of combining the final stages, namely the construction and operation stages, into the design process stage. The potential there is great, namely easy access and has the impression of green open space and surrounded by many trees that can provide fresh air. The problem is the limited parking space and the lack of proper facilities to use as well as the garbage that has accumulated on the shores of the lake. The land in the area has great potential as a natural tourist area. The types of activities that respondents want are camping, canoeing around the lake, and cycling, these activities can be carried out by providing special camping areas, repairing boat facilities, and providing paths for cycling. The basic concept that will be applied to the Lake Situ Gede tourist area is ecotourism with design concepts, organic patterns, and the shape of a cleaver. The results of the research are limited to the final product in the form of site plans, cut drawings, detailed drawings, and illustrations.
