Abstract

The use of plants for human needs is very high, especially among communities in suburban and rural areas. Communities are highly dependent on forests as their main source of sustenance. The purpose of this study was to determine the use of Nelambo Suon (Bikkia sp.) plant stems among the Yali tribe in Yahukimo Regency, Papua. The method used was a survey, which was conducted through field observations and interviews using questionnaires. This study was conducted in four villages, namely Sabelebi, Muhumu, Kinkun, and Ohena, in the Heriapini District of Yahukimo Regency, Papua Mountains. This study involved 43 respondents consisting of primary informants, key informants, and supplementary informants. The results of the study show that the Bikkia plant is widely used by the Yali tribe in the Papua Mountains. The bark can be used as a remedy for malaria, while the trunk is used to make sehen arrows, suap arrows, and wangkun sticks (for harvesting crops). As many as 88.37% of the community acknowledged that the trunk of this tree is very strong and can be used for various purposes. However, conservation efforts for this plant have not yet been undertaken by the community. Considering that Bikkia sp., found in Yahukimo, is one of several species with limited distribution in the world, conservation efforts are needed.

Abstract

The increasing generation of organic waste, particularly from household sources that are not properly managed, can have negative environmental impacts. One innovative solution is the utilization of waste for eco-enzyme production through fermentation, resulting in a liquid organic fertilizer product. On the other hand, arbuscular mycorrhizal fungi (AMF) are recognized as biological agents (biofertilizers) that can enhance plant nutrient uptake through mutualistic symbiosis with plant roots, thereby improving plant growth performance. This study aimed to evaluate the effectiveness of the combination of AMF and eco-enzyme on the growth of water spinach (Ipomoea aquatica) using a hydroponic system. The study employed a completely randomized design (CRD) with several treatments, namely: (1) control (without fertilizer), (2) positive control (AB-Mix chemical fertilizer), (3) eco-enzyme (liquid organic fertilizer), and (4) a combination of AMF + eco-enzyme, each with three replications. The results showed that eco-enzyme application did not have a significant effect. Although the addition of AMF and eco-enzyme resulted in plant height, leaf number, leaf area, root length, fresh weight, and dry weight, these responses were not superior to the control. Although the percentage of AMF colonies was high in I. aquatica, the use of AB-Mix fertilizer, either alone or in combination with AMF, still performed better than eco-enzyme.
