The purpose of this study was to see the effect of giving Vesicle Arbuscular Mycorrhizae (VAM) on the vegetative growth of white corn (Zea mays L), distance treatment of plant and interaction both of them on the vegetative growth of white corn. This study used a randomized block design (RBD) on factorial with two-factor and three replications. The first factor is the treatment of giving VAM (A) with various doses consisting of A1 (10 g/plot), A2 (20 g/plot) and A3 (30 g/plot), while the second factor is the treatment of plant spacing (J) with various sizes consisting of J1 (50 cm x 15 cm), J2 (50 cm x 25 cm) and J3 (50 cm x 35 cm). Data collection starts from planting to flowering, namely plant height, number of leaves, flowering time. Data analysis was carried out through analysis of variance and further test of DMRT at 95% confidence level. Based on the results of the study, it was found that the fungal treatment only had a significant effect on plant height and cob length, but did not significantly affect the number of leaves, flowering time. The plant spacing treatment only had a significant effect on plant height but had no significant effect on the number of leaves and flowering time. The interaction of the fungus treatment and plant spacing treatment showed that there was an interaction effect of the two treatments on plant height but did not significantly affect the number of leaves, flowering time. The treatment interaction A3J3 had the highest plant size of 114.55 cm.

Land clearing and drainage activities on peatlands had boosted the decomposition rate of organic matter, caused by an increase in soil temperature and soil microbial activity. Enzyme activity is a sensitive indicator to measure changes in the decomposition process. The enzyme activity associated with the decomposition of organic matter is Laccase. This research aimed to study Laccase as an indicator of lignin degradation in several types of peatland use in Pesisir Selatan, West Sumatra, namely forests, shrubs, oil palm plantations, agricultural land, and bare land. The Laccase activity was measured by using the ABTS method. The results of our study show that Laccase activity in several types of peatland use from the highest to the lowest follows the order: agricultural land (LP) 3.20 μg.g-1.hour-1 > bare land (LT) 1.46 μg.g-1.hour-1 > shrub (SB) 1.17 μg.g-1.hour-1 > smallholder oil palm plantation (PSr) 0.66 μg.g-1.hour-1 > private company oil palm plantation (PSs) 0.70 μg.g-1.hour-1 > forest (H) 0.06 μg.g-1.hour-1. Soil characteristics that affect the enzyme activity are water content, which is negatively correlated with the Laccase enzyme. The higher the water content in the peat material, the lower the Laccase activity. Therefore, it is necessary to control the soil water content high to prevent the rate of peat decomposition.
Keywords: Laccase, enzyme, oil palm plantation, land use, peatland.
A phenomenological study of the breastfeeding experiences of African American women and the implications of societal racialization
Authors: Knox-Kazimierczuk Francoise A. , Summers Crystal , Lotz Kevin V. 
Published: May 2023

Background. UNICEF & The World Health Organization (WHO) recommend exclusive breastfeeding for the first 6 months of life (UNICEF & WHO, 2017). Research has reported reduced risk for all selected pediatric diseases with breastfeeding durations meeting this recommendation. Despite the proven benefits, breastfeeding rates for low-income African American mothers remain far below the guidelines established by Healthy People 2030.
Purpose. The purpose of this research study was to explore the socio-cultural barriers and assets of breastfeeding experienced by African American mothers. The study was designed to elicit responses focused on barriers and facilitators of breastfeeding, specifically focusing on race as a key upstream determinant for both positive and negative experiences.
Methods. In this study, a hermeneutic phenomenological qualitative approach was used conducting focus groups and in-depth interviews. Eight African American WIC eligible mothers consented to participate in the study.
Results. Data was analyzed using two coders, who looked for themes within the text derived from participants’ experiences. Four main themes emerged from the experiences of the participants: (a) Healthcare provider bias, (b) Distrust/Fear, (c) Agency/Control, and (d) Support Networks.
Conclusion. This study offers a novel approach to examining disparities in breastfeeding rates, duration, and exclusivity through directly engaging low-income African American mothers. This study suggests culturally appropriate training for providers, increasing the diversity of providers, providing peer coaches, and support groups for African American women would be beneficial for African American WIC eligible women wanting to be successful at breastfeeding.

Antagonistic effect of T. harzianum was carried out on F. oxysporum f. sp. lycopersici. isolates of tomato variety (UC 82B) in a screen house located at the Teaching and Research Farm of Federal University of Agriculture, Makurdi during 2015 cropping season to determine the ability of the antagonistic in controlling Fusarium wilt diseases of tomato. The F. oxysporum isolates tested were coded as: FoAs1, FoAs2, FoAg, FoNb, FoSb, FoAm, FoAk, FoOr, FoAd and FoUAM together with an uninoculated control. The experiment was a 2 x 11 factorial laid out in Completely Randomized Design (CRD) and replicated three times. T. harzianum was introduced at three different times (Two days before, same time and two days after the inoculation of F. oxysporum). In vitro tests results revealed antagonistic effects of T. harzianum on F. oxysporum isolates. Growth inhibition was significantly higher (P≤0.05) when T. harzianum was introduced two days before inoculation of F. oxysporum. Interaction shows that T. harzianum introduced two days before inoculation of F. oxysporum gave better inhibition of all the Fusarium isolates tested except isolates FoAd and FoAg compared with when the antagonist was introduced at the same time and when it was introduced two days after inoculation of F. oxysporum. Also, T. harzianum (P≤0.05) totally inhibited the growth of isolates FoAg, FoAs1, FoNb, FoOr and FoUAM but not those of FoAd, FoAk, FoAm, FoAs2 and FoSb. It is therefore recommended that T. harzianum be used in the management of fusarium wilt disease of tomato

Water resources management is a hot topic in the world. Integrated Water Resources Management is a process that integrates water management, land, and other related resources in a coordinated way to maximize economic and social welfare equally without sacrificing the sustainability of vital ecosystems. The principle is formulated in the form of integration of natural systems and human systems, the last concerning the cross-sectoral integrity in policy development; the integration of stakeholders in the process of planning and decision-making and cross-regional integrity. Various water resources management institutions exist in Indonesia, but follow-up in water management is still weak. Some inefficiencies occur in water management in Indonesia. Implementation of existing water policies has not been in accordance with existing laws. The bureaucratic structure is ineffective, thus not contributing to the development of water governance in Indonesia. This study tries to compile and analysis of some best practices and constraints of interdependent relationships of stakeholders on the process of planning and decision making of integrated water management. The study took place at the Aceh-Meureudu River Basin in Aceh Province, which is one of the national-strategic river basins. The method used in this study was descriptive analytic which illustrate the inter-institution coordination at the river basin in water conservation activities, water resource utilization, and controlling the destructive power of water. The results of these compilations of water resources management in the river basin indicate the differences in implementation caused by differences in regulations between sectors at several district and provincial institutions, even though there is the scheme of water resources management made by and with the approval of Water Resources Management Coordination Team. Some of the planned management schemes were not implemented because of the conflict of regulations. The results of this evaluation should be input for improving the development of water resources management policies in the Aceh-Meureudu River Basin.
