Abstract

Oil palm empty fruit bunches (OPEFB) are underutilized waste. The combination of OPEFB fermentation and eggshell powder as a planting medium, aims to determine the effect of the combination of treatment differences in OPEFB fermentation time and composition of growing media on the growth of amaranth (Amaranthus tricolor). This study consisted of 6 treatment combinations, 4 replications, completely randomized factorial design method, with the parameters of plant height (cm), number of leaves (strands), and total fresh weight (grams). Data were collected at the age of 7, 14 and 21 DAP. Analysis of variance and the smallest significant difference test (BNT) level 5% were used. The results of the analysis showed that the composition of the growing media had a significant effect (Fcount > Ftable), From the results of the study, it was found that the most optimal treatment for the composition of the growing media was W2K3 treatment with a composition of 3 kg of soil, 20 grams of eggshell powder, and 200 grams of OPEFB fermentation for 21 days. The interaction factor of these two factors had a significant effect (Fcount > Ftable) on plant height 21 DAP (4.697 > 3.55).

Abstract

This study aims to determine the microplastic content in several types of shellfish in Tanjung Batu waters, Berau Regency. The type of research used is qualitative research, with descriptive analysis methods. The samples used in this study were blood clams (Anadara granosa) and cockles (Polymesoda erosa) taken from the sea waters of Tanjung Batu, Berau Regency, East Kalimantan. Observations were made at the Biology Education Laboratory, Teaching and Education Faculty, Mulawarman University. The results showed that blood clams (Anadara granosa) and cockles (Polymesoda erosa) contained microplastics. The types of microplastics found included fibers, fragments, and films. The type of microplastic that is found the most is fiber and the least is film.
