The expected results of the development of this park are the creation of comfortable green open spaces, increased tourist visits, and the opening of new business opportunities for the surrounding community. Thus, Sudimampir Hamlet Park is expected to become a sustainable tourist attraction and provide social, economic, and environmental benefits.

Wood consumption in Indonesia, which is expected to reach more than 64.84 million m³ by 2025, is putting enormous pressure on forests, as evidenced by the reduction in forest area through the clearing of 96,230 hectares of forest in 2023. To reduce dependence on wood as a building material, alternative materials with comparable physical and mechanical properties are needed. Bamboo, especially laminated bamboo, was chosen because it has high tensile strength, a short harvest time, and abundant availability. This study examines the behavior of hollow section laminated bamboo beam-column connections with a glue-in-rod-bracket system to determine the ductility of the connection under unidirectional (static) loads. An experimental method was used with the independent variables of diameter and number of bolts, while the dependent variables included the moment-rotation of the connection, stiffness, strength, and ductility. The results show that the average ductility values for 4 and 6 thread rods D6, D8, and D10 mostly meet the SNI 1729 (≥1.25) and AISC 360 (rotation >0.03 rad) standards, with classifications ranging from "partially ductile" to "fully elastic." However, the 10-diameter 6-thread rod only achieved a ductility of 1.2, thus failing to meet the SNI standard. Based on the Handbook of Structural Steel Connection Design and Details, all connections fall into the non-seismic category because their ductility values are less than 3. These findings confirm the potential of laminated bamboo as an environmentally friendly construction material, while also providing technical guidelines for the design of non-seismic beam-column connections.

The Soxhlet extraction method uses repeated heating and solvent circulation to separate substances from mixtures, producing more extract faster than maceration with less solvent. However, this method requires pure solvents and is not suitable for thermolabile compounds as they can be degraded by heat. Soxhlet extraction is more effective for limited quantities of dry and fine herbal materials. This method is widely used to extract phytochemical compounds such as flavonoids, tannins, and curcumin, and has potential in cosmetic raw materials, herbal medicines, and antioxidant products. Although it uses more energy, this technique is efficient and continuous. Modern innovations such as combining it with Ultrasonic Assisted Extraction (UAE) or environmentally friendly microextraction are expected to increase extraction efficiency while reducing the use of organic solvents. Modifications to Soxhlet, including automation and assistive technologies such as high pressure, ultrasound, and microwaves, open up opportunities for commercialization and further research with more optimal results and more practical operations. The modified Soxhlet is considered a “panacea” in extraction due to the significant performance improvements achieved.

The BIMP-EAGA Vision 2035 (BEV 2035) marks a significant paradigm shift in border management in Southeast Asia, with a primary focus on integrating a more inclusive, open, harmonized, and resilient system. In this context, sea-based border crossing posts (PLBN) in Indonesia, such as the Sebatik PLBN, the Serasan PLBN, and the Miangas and Marore Border Crossing Stations (BCS), play a strategic role as maritime connectivity nodes connecting Indonesia with neighboring countries. The transformation of these PLBNs faces several challenges, particularly related to the disharmony of CIQS (Customs, Immigration, Quarantine, and Security) regulations between countries, technical obstacles related to non-conventional vessels (NCSS), and inadequate port infrastructure. To overcome these obstacles, strategic measures are needed, such as revising cross-border trade agreements, increasing quarantine capacity and facilities, and strengthening maritime logistics networks between countries. Furthermore, the development of a sustainable blue economy in border areas is crucial to ensure that the PLBN functions not only as an administrative checkpoint but also as a key facilitator in driving economic growth based on maritime resources. Within the framework of the BIMP-EAGA Vision 2035, the Integrated Maritime PLBN is expected to reduce dependence on informal trade and improve the quality of life of border communities by accelerating connectivity, developing the maritime economic sector, and opening international market access for local products. Thus, the PLBN must transform into a catalyst for inclusive and environmentally friendly economic development in Indonesia's border regions.

This research examines the practices of a B4 class teacher at RA Takhrimah Tungkop in identifying children’s Multiple Intelligences (MI) through authentic observation during an activity of printing moon shapes using banana stems. The study employed a descriptive qualitative approach with data collected through in-depth interviews and participatory observation. Data were analyzed thematically and supported by source and technique triangulation to ensure the validity of the findings. The results indicate that the teacher’s understanding of the MI concept was still focused on linguistic, logical-mathematical, and visual-spatial intelligences. Despite this limited conceptual scope, the implementation of authentic observation during the art-based activity successfully revealed a broader range of children’s intelligences. The moon-printing activity demonstrated indicators of visual-spatial intelligence through shape recognition and composition, bodily-kinesthetic intelligence through hand–eye coordination and motor control, and intrapersonal intelligence reflected in children’s ability to manage emotions, maintain focus, and show persistence during the task. Repeated observations accompanied by anecdotal records enabled the teacher to construct individual and continuous MI profiles for each child. These profiles can be utilized to design more varied, contextual, and child-centered learning strategies that align with the characteristics of early childhood learners in the Raudhatul Athfal setting. The practices observed also illustrate the connection between Gardner’s MI theory and Islamic early childhood education grounded in concrete learning activities. The findings support the development of child-friendly learning environments and encourage teacher creativity in conducting activity-based assessments. This study recommends strengthening teacher competencies through training in authentic MI assessment and further research using a research and development approach.
