The methods included module development, teacher training (workshop), and learning implementation using a Project-Based Learning (PjBL) approach involving 18 seventh-grade students and 7 assisting teachers. Activities involved measuring cultural objects (like Tumoko Batu) and creating cultural products (like the Papuan Flute and Sentani Drum). The results showed a significant change, with students becoming more enthusiastic and active in discussions. Quantitatively, there was an average increase in conceptual understanding of 42.25% following the program implementation. This increase is supported by qualitative data showing improved student activity (reaching 80% in the presentation session) and the strengthening of cultural identity.

Case Study Evaluation of Road Network Connectivity in Center Banjarmasin

2026-01-16T05:54:51+00:00

Road network configuration is a permanent element of urban morphology that influences spatial utilization patterns, mobility, and public accessibility. Good network connectivity encourages the use of active and public transportation, while low connectivity increases reliance on private vehicles. This study aims to evaluate the performance of road network connectivity in Banjarmasin City, focusing on Banjarmasin Tengah District as the City Service Center (PPK), and comparing it with other districts. The study uses a quantitative approach with spatial data analysis for the 2021–2025 period using ArcMap software. Three indicators are used: the Road Density Index, the Beta Connectivity Index, and the Gamma Connectivity Index, with road segments as the unit of analysis according to the Indonesian Road Capacity Guidelines. The results show that Banjarmasin Tengah District has the highest road density, reflecting the availability of relatively good physical infrastructure. The highest beta connectivity values are also found in Banjarmasin Tengah and Banjarmasin Timur, although generally still in the low–moderate category. Meanwhile, gamma connectivity values across all districts are relatively low, with an average of around 13% of optimal conditions. These findings indicate the need to improve connectivity between segments, particularly in local and neighborhood road networks, to support a more efficient and sustainable urban transportation system.

The Youth Janger Festival for the Preservation of Banyuwangi’s Local Cultural Heritage

2025-10-31T01:51:56+00:00

The Janger performing art of Banyuwangi is a traditional cultural expression that combines dance, music, dialogue, and comedic oral performance in the Javanese language. Since the early twentieth century, Janger has served as a marker of cultural identity, a medium for moral education, and a space for social solidarity within the local community. However, over the past two decades, Janger has faced significant challenges, including a crisis of regeneration, linguistic shifts resulting from the mixture of Javanese, Osing, and Indonesian, declining performance frequency, and the commodification of art that threatens its authenticity. These conditions reflect a broader phenomenon occurring across Indonesia, where many traditional arts are pressured by modernization and globalization. Despite the rapid growth of cultural tourism in Banyuwangi—marked by major events such as Gandrung Sewu and the Banyuwangi Ethno Carnival—Janger has not gained a proportional position in cultural branding strategies. In fact, Janger holds strong potential as an authentic and educational cultural attraction, and it has been recognized as an intangible cultural heritage. The Youth Janger Festival program is proposed as a community-based cultural preservation effort aimed at revitalizing Janger through youth engagement, reinforcement of the Javanese language, and the implementation of a participatory festival, ensuring that this traditional art remains sustainable, adaptive, and rooted in Banyuwangi’s local identity.
