Abstract

This study aims to model Crude Birth Rates (CBR) in West Nusa Tenggara Province. The nonparametric regression method was used in this research by considering data distribution patterns that do not show a linear relationship between variables. In this case, the kernel nonparametric regression using the Gaussian function and the Nadaraya-Watson estimator. The results showed optimal bandwidths of 0.55542837, 1.29042927, 0.94706041, and 0.92278896 with a value of minimum Generalized Cross-Validation (GCV) of 0.000000000432613511, which was minimized by the simulated annealing algorithm. The resulting model's accuracy can be seen from the coefficient of determination (R2) of 99.23% and the Mean Absolute Percentage Error (MAPE) of 0.007049%.

Abstract

Plankton as a basic component in the structure of life in the waters, spesifically as water producers can be used as one of the parameters in monitoring the quality of the aquatic environment. The existence of aquatic tourism activities and quantitative and qualitative plankton can be used to determine the fertility of a waters, by measuring the abundance and distribution of plankton found at each depth. The research station is divided into three sites, site A is the source of the entry and exit of sea water, site B is in the middle of the lake, and site C is located close to the freshwater spring. Based on the results of research in the waters of Danau Dua Rasa Labuan Cermin, 8 classes of plankton were obtained with 24 species, there are the Chlorophyceae, Cyanophyceae, Chrysophyceae, Dinophyceae, Mastigophora, Crustacea classes. Sarcodina and Rotatoria. The Danau Dua Rasa Labuan Cermin are included in the Mesotrophic waters group. Because the abundance value reaches 9,513 ind/L, in other words, Labuan Cermin waters have a moderate fertility level that can support the breeding and survival of aquatic organism and the continuity of a good photosynthesis process.

Abstract

Tongkol fish is one of the abundant sources of animal protein and is easily found in coastal areas, including Pantai Amal Village. However, the utilization of tongkol fish by the community is still limited to traditional processing that is less varied. On the other hand, fellow students often face challenges in meeting daily nutritional needs due to economic limitations and instant consumption patterns that are low in nutrition. This study aims to develop innovations in processing tongkol fish into spicy shredded fish as an economical, nutritious, and practical food solution. The research methods include the production process, taste testing, and analysis of production and consumption costs. The results show that spicy shredded fish has a high protein content, a taste that consumers like, and a fairly long shelf life so that it is suitable as a daily food stock. In addition, this product is proven to be more economical than consuming fast food, so it is effective in helping students from out of town manage their expenses while meeting their nutritional needs. This innovation also has the potential to increase the added value of tongkol fish and support local food security in coastal areas.

Abstract

Penelitian ini bertujuan untuk menganalisis representasi kebijaksanaan dalam karakter Hutch Mansell dalam film Nobody (2021) menggunakan pendekatan semiotika Charls Sanders Peirce dan teori representasi Stuart Hall. Hutch digambarkan sebagai sosok ayah yang mengalami transformasi dari figure pasif menjadi sosok yang bijaksana dalam pengambilan keputusan untuk melindungi keluarganya, dengan memunculkan nilai utama kepahlawanan utama menurut Scott T. Allison, yakni kebijaksanaan. Temuan menunjukkan bahwa representasi tersebut terbentuk melalui unsur naratif dan sinematik yang kompleks, seperti simbol visual, dialog, dan tindakan karakter utama. Film Nobody memuat representasi konstruksionis dalam narasi kebijaksanaan yang ambivalen. Penelitian ini mengungkap bagaimana film aksi dapat menjadi media yang efektif untuk menarasikan peran ayah secara kompleks, mencerminkan nilai budaya dan ideologi maskulinitas dalam konteks keluarga.

Abstract

The global increase in life expectancy has significantly contributed to the growth of the elderly population, including in Indonesia, which has now entered the aging population phase with more than 10% of its total population aged 60 years and above. This demographic shift presents challenges in maintaining the quality of life among the elderly, particularly in tropical border regions such as Tarakan City. Karang Anyar Pantai Village, located in West Tarakan District, has a considerable number of elderly residents supported by existing elderly health posts (posyandu lansia). Social and health interventions through elderly exercise programs, nutritional support in the form of mung bean porridge, and regular monthly health check-ups are considered strategic efforts to improve physical health, metabolic function, and psychological well-being among the elderly. This study aims to evaluate the impact of these three interventions on enhancing the quality of life of the elderly in Karang Anyar Pantai. By assessing the effectiveness of these interventions, this research seeks to provide recommendations for improving elderly care programs in similar regions.
