PEMBERDAYAAN DESA WISATA BERBASIS SUMBER DAYA ALAM DI DESA KARANG SIDEMEN LOMBOK TENGAH

A maximum Management of tourism with tourist objects is interrelated and is very decisive in the progress of the tourist area. The development of tourist sites will have a positive impact on the economy, especially the economy of the middle class societ. The tourism location that is developing in the Central Lombok Regency is natural tourism in Karang Sidemen Village. Karang Sidemen village is one of the 99 tourist villages in West Nusa Tenggara. In general, the people who live in this area have relatively original traditions and culture. In addition, there are several supporting factors such as typical food, agricultural systems, and social systems that contribute to the uniqueness of a tourist village. Karang Sidemen Village is located in North Batukliang District, Central Lombok Regency. This village is located around the Tahura Nuraksa forest area, so that the community around the forest area makes use of the existing resources in the forest. This village has tourism potential that is quite developed in the community, one of which is Blue Lake. Community service activities are carried out in collaboration with the 2021 UNRAM Thematic KKN group with the theme Assistance for Karang Sidemen Tourism Village. The results of the activities that have been carried out are five work programs in the form of: floating jetty, crossing bridges, directions, making sapta charm boards and arrangement / gardening in the Blue Lake area. The impact is that the number of tourist visits increases and can increase the income of the surrounding community. Community service activities to help improve supporting facilities in order to advance natural resource-based tourism villages are very much needed. .

Berkembangnya lokasi wisata akan membawa dampak positif dalam bidang perekonomian khususnya perekonomian masyarakat menengah. Lokasi wisata yang sedang berkembang di wilayah Kabupaten Lombok Tengah adalah wisata alam yang berada di Desa Karang Sidemen. Desa Karang Sidemen merupakan salah satu desa dari 99 desa wisata yang berada di Nusa Tenggara Barat.. Pada umumnya penduduk yang tinggal di kawasan ini memiliki tradisi dan budaya yang relatif masih asli. Di samping itu terdapat beberapa faktor pendukung seperti makanan khas, sistem pertanian, dan sistem sosial yang turut mewarnai kekhasan sebuah desa wisata. Desa Karang Sidemen terletak di Kecamatan Batukliang Utara, Kabupaten Lombok Tengah. Desa ini berada disekitar kawasan hutan Tahura Nuraksa, sehingga masyarakat di sekitar kawasan hutan memanfaatkan sumber daya yang ada di hutan tersebut. Desa ini memiliki potensi wisata yang cukup berkembang di tengah masyarakat salah satunya adalah Danau Biru. Kegiatan pengabdian dilakukan dengan kerja sama dengan kelompok KKN Tematik UNRAM 2021 mengangkat tema Pendampingan Desa Wisata Karang Sidemen. Adapun hasil kegiatan yang telah dilakukan yaitu dihasilkan lima program kerja berupa : Dermaga apung, jembatan penyebrangan, petunjuk arah, pembuatan papan sapta pesona dan penataan/gardening di kawasan Danau Biru. Dampaknya jumlah kunjungan wisata meningkat dan dapat meningkatkan pendapatan masyarakat sekitar. Kegiatan pengabdian masyarakat untuk membantu meningkatkan sarana pendukung dalam rangka memajukan desa wisata berbasis sumber daya alam sangat diperlukan. .

Genomic analysis of a functional haloacid-degrading gene of Bacillus megaterium strain BHS1 isolated from Blue Lake (Mavi Gölü, Turkey)

Purpose Bacillus megaterium strain BHS1, isolated from an alkaline water sample taken from Mavi Gölü (Blue Lake, Turkey), can grow on minimal medium containing 2,2-dichloropropionic acid. We characterized this bacterium at the genomic level. Methods The HiSeq platform was used to carry out genome sequencing, de novo assembly, and scaffolding with strain BHS1. Next, genome data were analyzed to demarcate DNA regions containing protein-coding genes and determine the function of certain BHS1 genes. Finally, results from a colorimetric chloride ion–release assay demonstrated that strain BHS1 produces dehalogenase. Results De novo assembly of the BHS1 genomic sequence revealed a genome size of ~ 5.37 Mb with an average G+C content of 38%. The predicted nuclear genome harbors 5509 protein-coding genes, 1353 tRNA genes, 67 rRNA genes, and 6 non-coding (mRNA) genes. Genomic mapping of strain BHS1 revealed its amenability to synthesize two families of dehalogenases (Cof-type haloacid dehalogenase IIB family hydrolase and haloacid dehalogenase type II), suggesting that these enzymes can participate in the catabolism of halogenated organic acids. The mapping identified seven Na+/H+ antiporter subunits that are vital for adaptation of the bacterium to an alkaline environment. Apart from a pairwise analysis to the well-established L-2-haloacid dehalogenases, whole-cell analysis strongly suggested that the haloacid dehalogenase type II might act stereospecifically on L-2-chloropropionic acid, D,L-2-chloropropionic acid, and 2,2-dichloropropionic acid. Whole-cell studies confirmed the utilization of these three substrates and the gene’s role in dehalogenation. Conclusions To our knowledge, this is the first report of the full genome sequence for strain BHS1, which enabled the characterization of selected genes having specific metabolic activities and their roles in the biodegradation of halogenated compounds.

Ecological evaluation of natural water bodies in the south part of Noginscky Region Moscow District

Floristic composition of terrestrial and aquatic plants in the ecotopes of surface water bodies, Blue Lakes and Lake Biserovo, was studied to assess environmental health of aquatic ecosystems in the Moscow region. The research was carried out both in the field and in the laboratory. Blue Lakes were lacking aquatic vegetation and the dominant synusia of the following plant species was found along the coastal zone: meadow clover (Trifolium pratense L.), meadow bluegrass (Poa pratensis L.), sedge coastal (Carex riparia Curt.), chamomile (Matricaria chamomilla L.), plantain (Plantago major L.), Timothy meadow (Phleum pratense L.). The vegetation cover of Lake Biserovo was patchy: submerged vegetation was most widespread, Canadian Elodea (Elodea canadensis Michx.) was the dominant species. Pure thickets of vegetation were formed only by the common American water plantain(Alisma plantago-aquatica L.), lake cattail (Schoenoplectus lacustris L.), common reed (Phragmites communis Trin.) and sedge coastal (Carex riparia Curt). It should be noted that in all the studied water bodies, the pH of the water area can be classified as very clean: Blue Lakes (7.8), samples from Lake Biserov (8.32). Water samples from Lake Biserova had the highest turbidity (11.5), which was associated with the accumulation of particles of the silt fraction of the reservoir, which began the process of eutrophication, high anthropogenic load. According to the results of a comprehensive assessment (hydrological indicators, calculation of the Mayer index) of the studied samples from the reservoirs, it was concluded that the water area of the Blue Lake had the best environmental status in the Noginsk region.
