Abstract

AbstrakKawasan Karst Gunungsewu memiliki kondisi hidrologi yang khas sebagai akibat dari batuan yang mudah larut dan mempunyai porositas sekunder yang berkembang baik. Hasil penelitian terdahulu menyebutkan bahwa sebagian wilayah karst Gunungsewu yang merupakan area penyangga air banyak dialihfungsikan untuk kegiatan pertambangan. Analisis desertifikasi batuan karst menjadi penting diteliti dikarenakan mempengaruhi kerentanan ekosistem karst saat terjadi desertifikasi batuan. Desertifikasi batuan karst dapat diperoleh dari indeks batuan permukaan. Tujuan dari penelitian ini adalah untuk menganalisis desertifikasi dengan (1) mendeskripsikan persebaran tingkat desertifikasi, dan (2) data laju desertifikasi karst Gunungsewu menggunakan data spektral citra Landsat 8 OLI.Penelitian ini menggunakan penginderaan jauh dengan Normalized Difference Rock Index dan Normalized Difference Vegetation Index sebagai parameter menganalisis desertifikasi batuan karst. Jenis penelitian ini adalah diskriptif kuantitatif menggunakan analisis statistik spasial dan pengambilan sampel penggunaan lahan seperti lahan terbuka, tambang, pemukiman, vegetasi lebat, sawah, badan air dilakukan secara purposive. Pengambilan data dilapangan sebagai ground checking untuk mendapatkan data yang reliable.Hasil dari penelitian ini membuktikan bahwa persebaran tingkat desertifikasi batuan yang terjadi pada tahun 2019 karst Ponjong Gunungsewu didominasi oleh kriteria tingkat terdesertifikasi sedang tersebar dari selatan ke utara. Tingkat desertifikasi sedang memiliki kriteria tutupan vegetasi berkisar 20-40% dan singkapan batuan berkisar 50-70%. Kondisi tersebut mengalami tren laju desertifikasi menaik daripada 6 tahun sebelumnya.Kata kunci: Penginderaan Jauh, Desertifikasi Batuan Karst, Citra Landsat 8 OLI.

Abstract

This study investigates the presence of nationalist values within the narrative of early human cohabitation in cave shelters in Java, positioning it as a potential educational resource. The objective of this research is to examine how interactions between distinct racial groups, specifically Australomelanesoid and Mongoloid populations can be utilized to foster students’ nationalist consciousness. Employing a qualitative literature review approach, the study seeks to identify the embedded nationalist values in the inter-racial coexistence of prehistoric human communities in Java and assess their potential as learning materials to reinforce national identity among students. The findings of this research suggest implications for educational practice, advocating for the integration of prehistoric cohabitation narratives into the curriculum as a means to cultivate a deeper understanding of national identity and promote social cohesion among learners.

Abstract

This study examines the impact of Dutch Military Aggression I (1947) and Dutch Military Aggression II (1948–1949) on the political development of Indonesia during the early years of independence. Employing the historical method (heuristics, source criticism, interpretation, and historiography) and a qualitative diachronic-synchronic approach, the research analyses primary and secondary sources concerning internal political dynamics and the Republic of Indonesia’s international relations in the period 1947–1949. The findings reveal that both Dutch military aggressions paradoxically served as crucial catalysts for the acceleration of national political consolidation and maturation in Indonesia. The First Aggression triggered international condemnation, transformed the Republic’s status from “rebels” to a sovereign state defending its independence, strengthened national solidarity, and gave birth to the integration of armed struggle and diplomacy—the precursor to the Total People’s Defense doctrine. Meanwhile, the Second Aggression, marked by the occupation of Yogyakarta and the arrest of republican leaders, led to the establishment of the Emergency Government of the Republic of Indonesia (PDRI), closer civil-military coordination, unification of political parties and societal organizations, and heightened global pressure that ultimately resulted in the recognition of sovereignty in 1949. Overall, Dutch military pressure expedited the transformation of political structures, bolstered the legitimacy of the Republican government, and secured both de facto and de jure recognition of Indonesian independence.
