Published: September 2023

This study aims to determine how the effect of the growth of black soybean plants (Glycine max L.) with a verticulture system. This research was conducted on Jl. Ekarasmi Gg. Ekanusa III Kec. Medan Johor, Medan City, from September to November 2022. This study used a non-factorial randomized block design (RBD) consisting of one treatment factor with 3 levels and 6 repetitions, namely: M1 = 2 kg soil, M2 = 2: 1 (2 kg soil + 1 kg rice husk), and M3 = 2:1 (2 kg soil + 1 kg cocopeat). This research was designed by doing 6 repetitions. The parameters used in this study were plant height, leaf area index, total and total chlorophyll a b content, relative growth rate, N uptake, and number of root nodules. The results of this study were that the planting medium had a significant effect on almost every parameter but the planting medium had no significant effect on one parameter, namely N nutrient uptake, with levels of M1 and M3. From the results of the study, it can be concluded that the application of planting media to the vegetative growth of black soybeans has an influence on the vegetative growth of black soybeans on almost all parameters, but on the parameters of nutrient absorption, black soybeans have no real effect with planting horticulture systems.

This study aims to describe the effect of the verticulture system and spacing on the vegetative growth of two cultivars of black soybean (Gylcine max L.). This study used a factorial randomized block design (RBD) with two treatment factors and 4 replications, namely F1= cultivar (P) consisting of two levels, namely P1= soybean cultivar Detam 1 and P2 = soybean cultivar Detam 4 Prida. F2= plant spacing consists of two levels, namely J1= 20 x 10 cm and J2= 20 x 20 cm. The parameters used were plant height, leaf area index, chlorophyll a, b and total content, relative growth rate, net assimilation rate, and number of root nodules. The results obtained from this study plant spacing had a significant effect on several parameters with the best level, namely J2= 20 x 20 cm and soybean cultivars with P1= detam 1 level had a significant effect on plant height parameters. But the plant spacing and the two soybean cultivars (Gylcine max L.) did not have any interaction in each parameter. It can be concluded that the regulation of planting distances and two soybean cultivars has a significant effect on several parameters such as plant height, chlorophyll content tests a, b and total as well as measuring relative growth rates.

This study aims to analyze the quality of river water and the water quality status of the Marbau watershed in North Labuhanbatu Regency based on water quality criteria and to formulate a pollution control strategy that needs to be implemented. The method used is a quantitative descriptive method by analyzing the status of river water quality based on the pollution index. The results showed that the P1 value of Marbau river water ranged from 0.94 to 1.82. The recommended pollution control strategies are: 1) maintaining river protection zones involving environmental cadres and green communities in monitoring; 2) monitoring and controlling water pollution along the river; 3) improve river water quality monitoring; 5) supervision of the discharge of waste water into rivers; 4) granting permits for disposal of wastewater (IPLC) into rivers must pay attention to the condition of the capacity to accommodate river pollution loads and enforce environmental law against business actors who violate established environmental quality standards. In conclusion, the quality of the Marbau river has decreased with the water quality status being slightly polluted. The recommendations for water pollution control strategies that need to be implemented are progressive strategies.

This study aimed to determine the type, composition and density of mesodebris based on seasonal differences (periods I and II). Sampling was conducted using the purposive sampling method. There were 5 lanes of transects randomised to determine the sub-transect box. Mesodebris samples were taken by excavating surface sediments (± 3 cm) and filtered with 0.5 cm x 0.5 cm size at Lamaru beach, Balikpapan City. All samples were collected, grouped and counted to determine the type, number, weight and density of mesodebris. The analysis results showed that 6 types of mesodebris were found in the study site such as plastic, plastic foam, glass, cloth, wood and rubber. The highest mesodebris composition for the number category was plastic (80%) in period II, while the highest weight composition was found in period I at 51%. The density of mesodebris with the most number category was found in period II (1.64 amount/m2). From the results of the study it can be concluded that there was no significant difference in the mesodebris density between periods I and II at Lamaru Tourism Beach, Balikpapan City. The main sources of mesodebris in the study area come from tourist activities, local residents' activities on land, and water runoff from the Manggar River.

Published: September 2023

The aim of this study was to observe the use of blue light on phytochemical changes during cauliflower (Brassica oleraceae L., var. botrytis) germination and the correlation between the parameters measured. The treatment was in the form of giving blue light and dark conditions as a control. Measurement of phytochemical compounds including ascorbic acid, glucosinolates, isothiocyanates and myrosinase enzymes was carried out every day for 5 days of germination. This research method is experimental research. Data obtained from measurements for all parameters are presented in the form of mean ± standard error. Furthermore, all data were analyzed using analysis of variance (ANOVA). To determine differences between groups, Duncan's multiple range test (DMRT) was used at the 95% confidence level. All data analysis used SPSS software version 24.0 (IBM, Chicago, IL, USA). In addition, the measurement of the correlation between parameters is carried out using the Pearson rank correlation coefficient. The results showed that blue light treatment significantly increased all measured phytochemical parameters. A significant positive correlation occurred between myrosinase activity and isothiocyanate formation. The glucosinolate content of cauliflower sprouts remained high during observations in the blue light treatment compared to the dark conditions. Blue light induces isothiocyanate formation and higher myrosinase activity when compared to dark conditions. The conclusion from this study is that blue light significantly increases the phytochemical changes of cauliflower sprouts.
