Abstract

This research aims to determine the best-growing medium to support the growth of water spinach plants using aquaponic technology. The study used a non-factorial Completely Randomized Design (CRD) method. There were four types of planting media treatments, namely, rockwool (control), cocopeat (P1), pasir malang (P2), and burnt husk (P3), there were five growth parameters observed (plant height (cm), number of leaves, stem diameter (mm), wet weight (gr), and leaf color) were monitored once a week starting from 7 HST to 28 HST. Data were analyzed using variance at a confidence level of 5% and continued with the Duncan test (DMRT) at a level of 5%. The results showed that the type of growing medium affects the growth of water spinach. pasir malang provided the best results for all plant parameters. However, it was not significantly different from burnt husk, except for stem diameter, where pasir malang differed significantly from the other treatments. Rockwool, pasir malang, and the burnt husk produced better and healthier leaf colors compared to cocopeat.

Abstract

Mangrove forest is a permanent habitat and transit area for various fauna. In the mangrove community, it forms a mixed habitat between terrestrial and aquatic fauna groups. This study aims to analyze the composition of mangrove species and the abundance of insects. There are 3 research station on the mangrove forest ecosystem on Payum beach. Sampling was carried out using the Line Transect method, starting with making a line transect (50 meters) on the outermost mangrove stands and pulling them inland. On each transect line a plot measuring 10 x 10 m is placed, in each of which 5 subplots/quadrants measuring 1 x 1 m are placed. Each transect line consist of 3 plots and 15 sub-plots will be obtained, so there are a total of 45 sub-plots. Based on the research results, it was found that several types of macrobenthos live abundantly and are associated with mangrove ecosystems, such as Terebralia palustris, Terebralia semistriata, Nerita sp., Cassidula angulifera, Cerithidea sp., Telescopium telescopium. Four species of mangroves are found on Payum Beach, Merauke Regency, South Papua Province, namely Avicennia alba, Rhizophora apiculate, Sonneratia alba, and Aegialitis annulata. The insect diversity index in the mangrove forest on Payum Beach in Merauke is H'=2.61, which indicates that the environmental conditions of Payum Beach are still quite good and insect diversity is in the medium category. The evenness index of 0.42 is included in the medium category because human activities vary, and the dominance index is 0.63 because the Payum Beach mangrove forest has various types of insects with moderate dominance.

Abstract

Fire starter is a product used to ignite a flame, particularly when using firewood, and is considered a potential alternative solution for managing biomass waste in Indonesia. This study aims to determine the quality of fire starters made from sawdust, pine cones, and dry leaves, using stearic acid as an adhesive. The research consists of three stages: production of fire starter, quality testing, and data analysis. The ratios of biomass to stearic acid used in this study are 3:8, 2:7, and 1:6. The quality tests conducted include ignition time, burn duration, burning rate, flame height, and durability test. The results indicate that in the ignition time test, the fire starter made from dry leaves had the fastest ignition time (17 seconds). The burn duration test showed that sawdust was the best material (1,423 seconds). The burning rate test found that dry leaves had the best result (0.035 g/s). The flame height test revealed that sawdust produced the tallest flame (35 cm). For the durability test, all the fire starters had the same durability value (100%).
