Abstract

Litsea garciae Vidal, commonly known as engkala, is an endemic medicinal plant of Borneo with promising pharmacological potential. Vegetative propagation through shoot cuttings is a practical alternative to overcome the challenges of seed-based propagation. This study investigated the effects of cutting material source (seedlings and saplings) and soaking duration in 50% Rootone-F (0, 15, 30, 45, and 60 minutes) on the rooting and shoot growth of L. garciae shoot cuttings. A factorial experiment with a completely randomized design was applied, involving ten treatment combinations with five replications each. Results showed that cuttings derived from seedlings achieved 100% survival and rooting rates regardless of Rootone-F treatment. In contrast, sapling cuttings achieved optimal rooting only after 15 minutes of soaking. The interaction of cutting source and soaking duration significantly influenced root development, while shoot growth varied only with individual treatments. Notably, seedling cuttings produced roots that were 1.3 times longer than those from sapling cuttings; however, the dry weight of sapling roots was 1.5 times greater. The dry weight of roots soaked in Rootone-F for 15 minutes significantly increased by 1.3 to 2.8 times compared to the dry weight of roots soaked for other durations. The seedling cuttings produced 1.2 times more shoots than saplings. Interestingly, cuttings without soaking treatment in Rootone-F produced the same number of new leaves as those soaked for 60 minutes but significantly more than those soaked for other durations. These results are vital for optimizing the vegetative propagation technique of L. garciae by selecting the appropriate cutting source and timing for Rootone-F immersion.

Abstract

The Iban Dayak people use forest plants from non-timber forest products (NTFPs) as traditional food. The purpose of the study was to study traditional foods and to record the types of forest plants used, processing methods, and efforts to maintain their sustainability by the Dayak Iban community in Mensiau Village, Batang Lupar District, Kapuas Hulu Regency. Interviews with the determination of respondents by purposive sampling. The Iban Dayak tribe has 14 types of traditional foods that are used for daily needs, certain holidays, and traditional ceremonies using 56 types of forest plants (33 families). The families with the most species were 8 species of Arecaceae, 6 species of Zingiberaceae, and 5 species of Poaceae. A total of 37 species have the greatest usefulness value (UV) (1). The most widely used habitus were herbs (26,78%) The most widely used plant parts were leaves (49,25%). How to process it by cooking boiled, sauteed, and eaten directly (lalap). Conservation efforts are carried out based on the local wisdom of the Iban Dayak community with certain rules and carry out plant cultivation in forests, fields, gardens, and house yards.
