Abstract

The dynamic Industry 4.0 requires a workforce that meets industry standards. The quality of education, particularly in vocational high schools, significantly influences the quality of human resources. Vocational high schools are dedicated to preparing students to directly apply their learning in the working world. The aim of this research is to analyze production oriented learning using the teaching factory approach in motivating the production of 'siomay' at SMK 1 Warunggunung. This study employs a quantitative descriptive method and is validated through expert validation using the validity test based on Aiken's V index. Data collection is conducted through questionnaires, interviews, and documentation as supporting evidence. The research findings indicate that, based on the 7 indicators of the teaching factory from the Directorate of Vocational High School Development, the teaching factory approach at SMK 1 Warunggunung falls short of these 7 indicators. The analysis of the teaching factory approach toward student motivation yields an average score of 133.04 and an interval of 109, falling into the high category. This is depicted through descriptive statistical results, revealing that only a portion of students have low learning motivation and there is a need for focused guidance.  Keywords: Business World Industrial World, Industry 4.0, Learning Motivation, Teaching Factory,

Abstract

Cemara Beach in Banyuwangi Regency has a unique mangrove ecosystem with a river flow that limits the tidal area with the land behind it. This study aims to determine the structure and composition of mangroves in Cemara Beach and its zoning. The method used is a vegetation survey with a transect plot. Data were analyzed using ecological indices and zoning illustrated from the results of vegetation surveys and observations. The results show that the Casuarina equisetifolia species has the highest important value index (IVI) in tree-level vegetation with an IVI value of 128.29%, while the highest IVI at the sapling level is owned by the Rhizophora mucronata species of 86.72% and the Acanthus ilicifolius species of 64.41% at the seedling level. The species diversity index (H') and dominance index (D) of mangroves in Cemara Beach are classified as moderate with average values ​​of 1.21 and 0.35. Then the species evenness index (E) of mangroves in Cemara Beach is included in the high category with an average E value approaching one at 0.78, while the species richness index (R) is classified as very low with an average value of 0.93. The zoning formed in mangrove vegetation in Cemara Beach is in sequence from sea to land, namely Casuarina equisetifolia, Rhizophora mucronata, Acanthus ilicifolius, Avicennia alba, Sonneratia alba, and Excoecaria agallocha. These findings suggest the need for targeted conservation and rehabilitation strategies that consider the natural zonation and dominance patterns of mangrove species to maintain the ecological balance of Cemara Beach.

Abstract

Pramuka Island is one of the islands in the Seribu Islands which has a number of marine ecosystems such as seagrass and macrozoobenthos. The aim of this research is to determine the relationship between seagrass density and macrozoobenthos abundance. This research was carried out by applying the purposive sampling method to determine research locations at 3 stations and 3 plots with 50 m transect lines and Pearson Product Moment or simple correlation analysis to determine the relationship between seagrass density and macrozoobenthos abundance. The seagrass species found on Pramuka Island form mixed vegetation with 5 seagrass species and the highest density is Thalassia hemprichii. The macrozoobenthos found included the Holothuroidea, Bivalvia and Gastropod classes with the highest abundance being the Holothuroidea class. The relationship between seagrass density and macrozoobenthos abundance shows a strong relationship with a correlation value of 0.997 and shows a positive (+) linear direction, meaning that the higher the seagrass density value, the higher the macrozoobenthos abundance.
