Abstract

Rawa Jombor is a semiartificial reservoir whose contruction are works for serving the needs of irrigation in the dry season and as a floading control in the rainy season. Rawa Jombor also used for fish farming and floating restaurant by the community. The existence of the cages and floating restaurant can have a negative impact to the aquatic environment due to the disposal of waste and leftover food and metabolism that is deposited at the bottom of the water. This study aims to analyze the water quality, pollution levels and to develop a management strategy of Rawa Jombor. Water quality is measured at 9 sampling point determined by purposive sampling based on the use of Rawa Jombor. Pollution level is analized uses pollution index and the management strategy uses analytical Herarchy Process. The results show that Rawa Jombor has decreased water quality marked by several parameters that do not meet the class III of water quality standards according to Government Regulation No. 82 of 2001. Rawa Jombor is included in the category of mildly polluted in areas without activity, floating restaurant and fish cage for water allotment class I, II, III and IV with an average pollution index ranging from 1,02 to 2,886. To maintain the continuity of the Rawa Jombor, a management strategy with priority on the economic aspects is needed with the development of the Rawa Jombor for sustainable fisheries.

Abstract

Rawa Jombor merupakan waduk semi alami yang dimanfaatkan oleh masyarakat untuk kegiatan budidaya ikan dalam keramba dan sebagai obyek wisata warung apung. Adanya aktivitas masyarakat ini membawa dampak pada kualitas air akibat limbah yang terbuang ke badan air, seperti kegiatan budidaya ikan di Rawa Jombor yang lebih banyak menggunakan pakan buatan sehingga dapat menjadi bahan pencemar bagi perairan akibat buangan sisa pakan dan kotoran ikan di dalam badan air. Tujuan dari penelitian ini adalah untuk menganalisis komunitas fitoplankton serta menentukan tingkat pencemaran Rawa Jombor berdasarkan pada indeks saprobik fitoplankton. Sampling dilakukan pada 8 titik yang ditentukan secara purposif dan identifkasi fitoplankton dilakukan menggunakan sedgewick rafter cell counter di bawah mikroskop. Hasilnya menunjukkan bahwa terdapat 9 kelas dan 47 spesies fitoplankton yang ditemukan di Rawa Jombor. Bacillariophyceae merupakan kelas yang dengan persentase tertinggi (34%). Kemelimpahan fitoplankton berkisar dari 72.525 hingga 111.000 ind/liter. Jenis fitoplankton dengan kemelimpahan tertinggi yaitu Melosira sp. dan Synedra sp. Indeks diversitas fitoplankton berkisar dari 1,264 hingga 1,485 yang termasuk kategori sedang, indeks dominansi berkisar dari 0,339 hingga 0,394 (tidak ada dominansi), indeks keseragaman berkisar dari 0,417 hingga 0,501 yang tergolong dalam kategori sedang. Indeks saprobik fitoplankton berkisar berkisar dari -0,11 hingga 1,6 yang termasuk dalam kategori α-mesosaprobik (tercemar sedang) hingga oligosaprobik (tidak tercemar). Secara keseluruhan, perairan Rawa Jombor tergolong kategori β-mesosaprobik dengan status tercemar ringan.

Abstract

Masyarakat Desa Tesbatan menghadapi tantangan rendahnya pemanfaatan potensi lokal sebagai sumber ekonomi baru, akibat keterbatasan pengetahuan dan keterampilan dalam pengelolaan wisata berbasis alam dan budaya. Kegiatan ini bertujuan untuk meningkatkan kapasitas Kelompok Tani Hutan Sismeni dalam mengelola potensi lokal menuju pengembangan desa wisata berbasis partisipatif. Desa Tesbatan memiliki kekayaan alam dan budaya seperti air terjun, kawasan hutan, seni tradisional, kuliner lokal, dan kerajinan tangan yang belum dimanfaatkan secara optimal. Metode yang digunakan meliputi penyuluhan, diskusi kelompok terfokus (FGD), praktik lapangan, serta evaluasi pre- dan post-test. Hasil kegiatan menunjukkan peningkatan signifikan dalam pemahaman peserta terhadap potensi wisata desa, yang ditunjukkan dengan kenaikan skor rata-rata dari 66,36 menjadi 91,82, atau sebesar 38,35%. Selain itu, kegiatan ini menghasilkan peta potensi awal, rencana aksi sederhana, dan dokumentasi visual yang dapat dimanfaatkan untuk promosi digital desa wisata. Kesimpulannya, pendekatan partisipatif terbukti efektif dalam meningkatkan kapasitas dan keterlibatan masyarakat dalam pengembangan desa wisata yang berkelanjutan. Secara ilmiah dan sosial, kegiatan ini berkontribusi pada penguatan model pemberdayaan masyarakat berbasis potensi lokal, serta membuka peluang riset lanjutan mengenai efektivitas promosi digital dan keberlanjutan kelembagaan desa wisata.

Abstract

Seaweed plays an important role in the implementation of the Blue Economy concept in Indonesia, as it not only serves as a commodity that supports the economy of coastal communities, but also has the potential to enhance national food security, mitigate the impacts of climate change, and promote sustainable marine resource management practices. The waters of Tesabela Village represent one of the potential areas that can be developed as a seaweed aquaculture center in Kupang Regency. The purpose of this research is to generate a site suitability map for seaweed cultivation in the marine area of Tesabela Village, Kupang Regency. Sampling points were determined using purposeful random sampling, but within the entire area. A total of six sample points were selected. Sample points one through six represent the waters of Tesabela Village. Secondary data was also collected to provide additional information for the geographic information system. The analysis showed that three stations were categorized as highly suitable (S1): stations 4, 5, and 6, with a total area of ​​96.57 ha. Stations 1, 2, and 3 were categorized as suitable (S2), or acceptable, with an area of ​​80.48 ha. These factors have the potential to reduce productivity, but farmers can generally address them through technical adjustments. Furthermore, seaweed farmers still need more support from the government and the private sector to maintain the sustainability of their farming operations and to conduct further research.

Abstract

The Tesbatan region, located in the Amarasi District of Kupang Regency, is rich in biodiversity and local cultural heritage, making it a potential hub for ecotourism development. This study aims to develop a comprehensive strategy for biodiversity conservation and creative economic ecotourism to promote sustainable growth in the region. The primary objective is to combine conservation efforts with local economic empowerment through creative industries such as handicrafts, traditional cuisine, and cultural performances. This research utilizes a systematic approach that includes field surveys, literature reviews, and the application of tools like MICMAC, MACTOR, and ISM for data analysis. Data was collected through observations, interviews, questionnaires, and Focus Group Discussions (FGDs) with local stakeholders. The study identifies key variables, influences, and stakeholders involved in the management of biodiversity and ecotourism. The findings suggest that integrating biodiversity conservation with ecotourism and creative economic activities can enhance both environmental sustainability and local community welfare. The proposed strategies involve strengthening local institutions, promoting participatory resource management, and developing integrated ecotourism attractions. In conclusion, this research provides a practical framework for managing Tesbatan’s natural and cultural assets sustainably, fostering both environmental protection and socio-economic development.
