Abstract

The purpose of this study was to identify the customary community forest of Soug tribe of Arfak in using customary forest resources surrounding Tobou forest. Through the study, how the forest assessed, local culture, forest preservation, transfer knowledge, accessibility, and infrastructure towards the existence of Tobou customary forest. The descriptive method was used to qualitative data. In order to obtain data, interview, and field observation was applied. In terms of customary forest use around Tobou, there were numbers of conserving land types such as garden opening, extracting both, timber and non-timber forest products, important value and trust, co-benefit interaction among social and biophysical co-benefit as a whole ecosystem component and customary role community. It turned out that social bonds among community strata were glaringly seen through customary roles as it has been indicated strongly in Arfak ethnic.

Abstract

Penelitian ini bertujuan untuk mengetahui kandungan fitokimia dan bioasai, antioksidan, antibakteri dan sifat toksisitas ekstrak metanol dari bagian tanaman Piper aduncum L. Metode pengujian yang digunakan adalah pengujian fitokimia, pengujian antioksidan, pengujian antibakteri dan pengujian toksisitas. Hasil pengujian menunjukkan bahwa ekstrak fitokimia daun Piper aduncum L mengandung triterpenoid dan steroid. Akar mengandung alkaloid tanin dan flavonoid kumarin. batang mengandung flavonoid dan kumarin. Uji antioksidan menunjukkan bahwa konsentrasi 25, 50 dan 100 ppm dalam ekstrak daun Piper aduncum masing-masing adalah sekitar 28,98, 43,67 dan 65,45%. Pengujian antibakteri ekstrak dari Piper aduncum menunjukkan hasil positif menghambat zona perkembangan bakteri yang memiliki sifat antibakteri. Hasil uji Brine Shrimp Lethality Test (BSLT) yang dihitung dalam penelitian ini memperoleh nilai LC50 mencapai 465,21 mg/ml yang berarti berpotensi sebagai antikanker.

Abstract

Land cover change represents a dynamic phenomenon driven by human activities and rapid regional growth, particularly in Palangka Raya City. This study aimed to analyze the historical dynamics of land cover changes during the 2016–2020 period and predict development trends for 2028 and 2040. The methodology integrated Cellular Automata and Artificial Neural Network (CA-ANN) models utilizing the MOLUSCE plugin within Geographic Information System software. Several driving factors were incorporated into the modeling process, including distance from road networks, distance from rivers, slope, elevation, and population density. The analysis revealed a significant transition from natural vegetated areas, such as peat swamp forests and shrublands, into anthropogenic land uses, specifically oil palm plantations and built-up areas. Model validation was performed using the Kappa coefficient test, which yielded a high level of accuracy, thereby confirming the reliability of the model for spatial projection purposes. The prediction results for 2028 and 2040 provided critical spatial insights regarding the potential continuous expansion of built-up areas. These findings were intended to serve as a crucial reference for local governments in formulating sustainable spatial planning policies to mitigate future environmental degradation.
