Urban floods frequently occur in Southeast Asian cities, causing extensive road disruptions and a significant decline in overall urban mobility. To effectively adapt to such conditions, it is crucial to understand how residents modify their travel behavior and daily activities during flood events. This study investigates these behavioral changes by comparing individual travel behaviors and activities under normal and flooding conditions, based on an Activity Diary Survey conducted in Kudus, Indonesia. The comparative analysis reveals that during floods, individuals tend to reduce non-essential activities and limit travel to essential purposes such as work and education. The findings from chi-square tests and applying the RF (random forest) model indicate that socioeconomic characteristics—particularly age, license, income, and level of flood—significantly influence the likelihood of behavioral change. These results highlight that flood-induced disruptions in mobility are not only physical but also socially differentiated, reflecting disparities in vulnerability and adaptive capacity.

The problems that often haunt radicalism among the younger generation are a serious challenge to the integrity of the Republic of Indonesia. With the form of actions to separate themselves from the nation, create their own group alliances, and others that cause the integrity of the state and religion to be at stake. Character education based on Ahlussunnah wal Jama'ah (Aswaja) offers a peaceful prevention approach through the values of moderation in religion, tolerance, and nationalism. This study aims to analyze and understand in depth the Role of Aswaja-Based Character Education in Preventing Radicalism. The method used is qualitative descriptive with case studies in educational institutions that implement the Aswaja curriculum. The steps taken in using literature studies, in-depth interviews and documentation. The data analysis method in this study uses steps, namely data reduction, data display (presentation) and conclusions. While checking the validity of the data using triangulation. strategies to prevent students' understanding of radicalism, The results of the study show that the integration of Aswaja values in intracurricular and extracurricular activities is effective in forming moderate and tolerant student characters. The conclusion of this study confirms the importance of Aswaja-based character education as a deradicalization strategy in the educational environment. First, by increasing the religious rituals of Ahlusunah waljamaah. and forming positive habits in teaching Aswaja values. While the implication is to develop Aswaja learning and instill the noble values of Aswaja to students. So that they are able to fortify themselves from the influence or invitation of radical groups.

Sekuro is one of the villages in the Mlonggo sub-district, Jepara Regency. Geographically, Sekuro village has a lot of potential because of its strategic location. Apart from that, Sekuro Village also has potential human resources that have not yet been absorbed. To achieve the goal of Community Service, namely the creation of creative products to realize an increase in the community's economy and to solve problems currently being faced by the Sekuro village community in particular. So the approach method used is direct practice and mentoring methods along with teaching aids direct practice methods. The implementation of community service activities is focused on the Sekuro village community who have an interest in fly ash and bottom ash waste management and those who have pilot building material businesses. Some of the programs that have been implemented, namely the offer of cooperation in paving blocks for village development, training in making products from this waste. All participants looked enthusiastic in participating in the whole series of service activities carried out. So that from these activities there is input for assistance to be carried out to market the products produced in the form of paving, bricks, and ornaments.

Jalan Raya Jepara - Bangsri merupakan Jalan Provinsi dan termasuk jalan yang mengalami kerusakan jalan yang cukup parah. Sehingga diperlukan adanya analisis yang mengkaji tentang beberapa jenis kerusakan jalan tersebut serta penanganan yang sesuai dengan kerusakan jalan tersebut. Berdasarkan hasil analisis yang didapat jenis kerusakan yang terjadi pada ruas Jalan Raya Jepara-Bangsri KM 16 s/d KM 18 jika ditinjau dengan metode PCI dan Bina Marga memiliki peresentasi kerusakan sebesar Retak buaya (38,75%), Retak Blok (17,39%), Retak Pinggir (8,89%), Lubang (17,49%), Tambalan (12,99%), Pengausan (10,89%), dan amblas (3,59). Untuk penilaian kondisi jalan dengan metode PCI diperoleh rata-rata sebesar 55,523 yang termasuk dalam kategori sedang (Fair), sedangkan untuk metode Bina Marga diperoleh rata-rata nilai urutan prioritas sebesar 7,2. Hasil dari keduanya memiliki jenis penanganan yang sama yaitu Pemeliharaan Rutin. Untuk menghindari kerusakan jalan yang semakin parah maka perlu adanya perhitungan mengenai rencana tebal lapis tambahan perkerasan lentur. Berdasarkan hasil jenis nomogram 3 dengan Ipt = 2,0 dan Ipo = 4 sehingga diperoleh tebal perkerasan laston AC-WC (lapis aus) tebal 7,5 cm, AC-BC (lapis antara) tebal 10 cm, dan Lapis pondasi Sirtu kelas A tebal 12 cm.

This study investigates the effect of NaOH molarity (10, 12, and 14 M) on gel formation at the geopolymer–artificial aggregate interfacial transition zone (ITZ) for sustainable pavement binder courses. The study focuses on microstructural and chemical characteristics rather than direct mechanical performance. Using XRF, FTIR, and SEM–EDX analyses, the evolution of gel phases from N-A-S-H to hybrid N/C-A-S-H at the interface was systematically characterized. Increasing NaOH molarity enhanced aluminosilicate dissolution and promoted Ca incorporation, as evidenced by the shift of the main Si–O–T band from approximately 1080 cm⁻¹ (10 M) to 960–970 cm⁻¹ (14 M) and the increase in Ca/Si ratio from 0.15 to 0.22. Among the investigated mixtures, the 12 M variant exhibited the most homogeneous and compact ITZ microstructure, characterized by a continuous reaction rim, balanced Si/Al (2.96) and Ca/Si (0.22) ratios, and minimal microcracking observed at the microscopic scale.
