Abstract

Staurastrum is a microalgae from the family of Desmidiaceae which is abundant in freshwater. The purpose of this study was to determine the diversity of Staurastrum and the abundance of the population of Staurastrum in the Sentani Lake Jayapura. The study was conducted in March 2018 in the Sentani Lake Jayapura. The sampling method used was the survey method by sampling water in 6 locations (Kampung Yakonde, Ifale, Hobong, Kalkhote, Ayapo, Puay) on the edge and center of the lake. The results showed that 4 species of Staurastrum on the Sentani Lake were S. arachne, S. diacathum, S. gracile and S. incisum The abundance of the Staurastrum population highest at the location of Ayapo (103), Puay (94), Hobong (89), Kalkhote (81), Ifale (77) and Yakonde (8). In terms of the similarity index, there are 7 sampling points that are very similar, 23 that are similar, 20 that are dissimilar, and 16 that are very dissimilar. The difference in sampling location shows that sampling in the central part of the lakes has a higher population abundance compared to edge of the lake. In conclusion there are 4 species of Staurastrum, the location of Ayapo is higher in abundance, and the central part of the Lake is higher in abundance.    Key words: Desmidiaceae; Jayapura; Lake; Sentani; Staurastrum.

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.
