Social Capital as A Pathway to Well-Being: A Study of The Cibulao Hijau Forest Farmer Group
Get PDFSocial capital was one of the key factors in the development process, as it emerged from social relationships and, when collectively utilized, could influence the level of well-being. Well-being in this context did not only refer to material needs but also encompassed spiritual and social aspects. This study generally aimed to analyze the relationship between the level of social capital functionality and the well-being of members of the Cibulao Hijau Forest Farmer Group. The study involved 35 group members selected using a simple random sampling technique. A quantitative approach was employed, supported by qualitative data. Data were collected through questionnaire distribution, in-depth interviews, observation, and literature review. The data were analyzed using descriptive statistics and Spearman’s rank correlation test. The results showed a significant correlation—categorized as moderate—between the functionality of social capital and the well-being level of group members. These findings indicated that the functionality of social capital served as one of the crucial indicators in determining the well-being level of the Cibulao Hijau Forest Farmer Group
Pengelolaan Konten Publikasi Desa Wisata: Menciptakan Keunggulan Daya Saing dan Pengelolaan Berkelanjutan
Get PDFThe adoption of digital technology has a significant impact on tourism management. The results released by the Organization for Economic Co-operation and Development (OECD) explain that tourism management needs to optimize the role of technology. However, many tourism managers have not implemented technology, including the management of publication content. Limited knowledge, lack of HR competency, and financial conditions are obstacles that arise. On the other hand, tourism managers who implement technology also face problems. The creativity of publication content and the ability to evaluate strategies are additional problems. This study aims to investigate the management of publication content in high-achieving tourist villages. This study uses a qualitative method through an interpretive perspective. Several high-achieving tourist villages in the Special Region of Yogyakarta and Central Java were selected as objects in this research. Qualitative analysis using the Miles Huberman method was used in this study. The results of the study explain that tourist villages can attract tourist visits through the creativity of publication content. This study produces findings on publication content management, including the need for the role of internal managers, the ability to choose themes and content ideas, the intensity of posts, the use of appropriate social media, and improving HR capabilities. The findings in this study are expected to be a role model for managing tourist village content as an effort to create sustainable management

Induksi Ketahanan Tanaman Tomat terhadap Ralstonia syzygii subsp. indonesiensis Menggunakan Bakteri Endofit dan Asam Salisilat : Induction of Resistance in Tomato Plants Against Ralstonia syzygii subsp. indonesiensis Using Endophytic Bacteria and Salicylic Acid
Get PDF Patogen Ralstonia syzygii subsp. indonesiensis adalah penyebab penyakit layu bakteri pada tanaman tomat. Patogen ini sulit dikendalikan karena kemampuannya bertahan dalam sisa bahan inang, tanah, dan dapat menyebar dengan mudah melalui aliran air, serta menginfeksi jaringan tanaman secara sistemik. Belum ada pestisida kimia yang efektif untuk mengendalikan patogen layu bakteri. Oleh karena itu, alternatif pengendalian yang dipilih ialah dengan menggunakan bakteri endofit dan asam salisilat. Dua jenis bakteri endofit, yaitu Arthrobacter sp. dan Bacillus thuringiensis, serta asam salisilat digunakan dalam penelitian secara tunggal ataupun kombinasi untuk mengevaluasi potensinya dalam menginduksi ketahanan tanaman tomat dalam menekan penyakit layu bakteri R. syzygii subsp. indonesiensis. Penelitian dilakukan dengan rancangan acak lengkap non faktorial dengan 14 perlakuan terdiri atas perlakuan tunggal dan kombinasi. Setiap perlakuan terdiri atas tiga unit tanaman dan tiga ulangan. Hasil penelitian menunjukkan bahwa kombinasi Arthrobacter sp. dan asam salisilat yang diaplikasikan satu kali seminggu (ABAS1) merupakan perlakuan yang paling efektif untuk menginduksi ketahanan tomat. Hal ini tampak pada periode inkubasi yang paling lama, rendahnya insidensi dan keparahan penyakit, meningkatnya aktivitas enzim peroksidase, polifenoloksidase, dan jaringan xilem tidak dominan terkolonisasi patogen pada pengamatan histopatologi.Induction of Resistance in Tomato Plants Against Ralstonia syzygii subsp. indonesiensis Using Endophytic Bacteria and Salicylic Acid
Ralstonia syzygii subsp. indonesiensis causes bacterial wilt disease in tomato plants. This pathogen is difficult to control because the pathogen can persist in residual host material, and soil, and easily spread through water and infected plant tissue systemically. There are no chemical pesticides available to control bacterial wilt pathogens. Therefore, the alternative is biological control using endophytic bacteria and salicylic acid. Two endophytic bacteria, namely Arthrobacter sp. and Bacillus thuringiensis, as well as salicylic acid, were used in research singly or in combination to evaluate their potential in inducing tomato plant resistance in suppressing the bacterial wilt disease R. syzygii subsp. indonesiensis. The research uses a non-factorial completely randomized design with 14 single and combination treatments. Each treatment consisted of three experimental units and was repeated three times. The results showed the combination of Arthrobacter sp. and salicylic acid applied once a week (ABAS1) was the most effective treatment in inducing tomato resistance. Evidenced by the longest incubation period, low incidence and disease severity, increased peroxidase, polyphenol oxidase activity, and xylem tissue was not predominantly colonized by pathogens in histopathological observations
Isolation and Molecular Identification of Nitrate-Reducing Bacteria from Swiftlet Houses in Sumedang, West Java
Get PDFEdible bird‘s nest is an important export commodity that is currently of concern to the Indonesian government. One of the requirements for exporting edible bird’s nest to the People\u27s Republic of China is that this product must meet the requirements for nitrite content in the product below 30 ppm. This nitrite contamination can be obtained from the results of nitrogen metabolism from nitrifying bacteria. However, information on nitrite-reducing bacteria in swiftlet houses has never been reported and is urgent in controlling nitrifying bacteria in swiftlet houses. The presence of nitrite-reducing bacteria needs to be identified to prove the presence of these bacteria in swiftlet houses that have the potential to contribute to nitrite contamination in edible bird’s nest. This study aims to isolate nitrate-reducing bacteria in an effort to control nitrite using bacteriophages in the future. This study targeted nitrate-reducing bacteria collected from environmental samples (waste, feces, pond water, artificial pond water, soil, swiftlet eggshells, white edible bird’s nest (Aerodramus fuciphagus), black bird’s nest (Aerodramus maximus)) (n=40) from two different swiftlet houses in Sumedang, West Java, Indonesia. All isolates collected were subjected to a series of microbiological tests, phenotypic characterization (Gram staining, morphology, sugar fermentation ability, enzymes, etc.) and genotyping by PCR amplification and 16S rDNA gene sequencing. Raw sequencing data were analyzed using DNASTAR® software for DNA sequence alignment and phylogenetic tree construction. In the present work, four bacteria species were identified, including Priestia megaterium, Pseudomonas putida, Stenotrophomonas maltophilia, and Proteus terrae. To our knowledge, this study is the first report of nitrate-reducing bacteria isolated from birdhouses.Edible bird‘s nest is an important export commodity that is currently of concern to the Indonesian government.

Development of Planting Media for Agricultural Land Prone to Waterlogging
Get PDFWaterlogging is a serious problem currently being faced in the agricultural sector. Climate change has increased the frequency of extreme rainfall events, which has increased the potential for agricultural land flooding. Therefore, innovations in planting media that can float during waterlogging are required. The purpose of this study was to create a planting medium based on simple automatic water flow and excess water control using a climate-based approach and plant water needs. The study stages were divided into three categories: climate data, planting media design and simulation, and field tests. The results of this study show that the design of planting media that considers plant water needs based on the amount of water lost can save water. The application of a drainage system on the side of the planting media prevented plant death in the planting media due to waterlogging, based on projections of an increase in extreme R-events. The use of plastic bottles in the design of the planting media was effective in providing buoyancy to the planting media during waterlogging. The developed planting medium is suitable for adaptation to agricultural land that is prone to waterlogging amidst the threat of the climate crisis that the world is currently facing
