Abstract

Local people in Rhepang Muaif Village, Nimbokrang District, Jayapura Regency usually use forest tree bark of three species, especially Dakwab wood, as raw material for noken, Papuan traditional woven bags. This study aimed to 1) scientifically identify the species of trees used for noken, 2) describe how to process fiber as a raw material, and 3) reveal the source of natural dyes used. Data collection was carried out using survey method, semi-structured interviews and participant observation. The result shows that in Rhepang Muaif, some species are used as raw material for noken, mainly species of Dakwab tree (Grewia paniculata). Dakwab fibers are generally coloured with natural dyes derived from Merei plant (Bixa orellana) for red colour and turmeric (Curcuma domestica) for yellow colour. The process of utilizing Dakwab bark as a noken fiber material starts from debarking the tree, stripping the bark, then washing, drying, and making the fiber from tree bark, later colouring if necessary and finally woving or knitting the fiber to become the bag.

Abstract

Tropical frontier regions such as Keerom Regency in Papua, Indonesia, face increasing pressure to expand food production under the National Strategic Projects (PSN) for food security. However, the absence of baseline data on soil fertility and water quality constrains the design of sustainable management practices. This study evaluated the temporal variation in soil chemical properties and aquaculture water quality to establish scientific benchmarks for site-specific interventions. Soil samples from chilli pepper (Capsicum annuum) farms were collected across resting, early growth, pre-harvest, and intercropping stages, while water samples from catfish (Clarias spp.) ponds were obtained during larval, grow-out, and harvest phases. Soil pH declined from 6.5 to 4.4, accompanied by reductions in total N, P, and K and a gradual rise in EC, indicating nutrient depletion and increasing acidity. In aquaculture ponds, DO levels decreased while Ammonium and nitrite accumulated during intensive feeding, suggesting excessive organic loading and incomplete nitrification. These results reveal critical limitations in both systems that reduce productivity and environmental resilience. The findings provide essential baseline data for nutrient management, fertilizer optimization, and water-quality control, forming a scientific foundation for future integrated agriculture–aquaculture (IAA) development to strengthen regional and national food-security initiatives in Papua.
