Water management in the paddy area in MADA

Water management is an important element in the paddy production. Water management can increase the productivity level, thereby increase the income of farmers. Water management system in MADA is divided into irrigation and drainage. The water storage under irrigation system covers three dams, namely Pedu, Ahning and Muda reservoir. This study examined the weaknesses of irrigation and drainage system in the MADA area. Among the problems are infrastructure density, very tiny road and the distance from the irrigation to the drains. Besides, water control in these areas is insufficient due to high and low paddy field areas. Therefore, several measures were identified to increase the efficiency of water management. Among them are implementation of reticulation system for irrigation and drainage, utilisation of booster and mobile pumps, construction of bunds and good farm practices. Apart from the modernised machines, good water management should be practised by paddy farmers to ensure the efficient use of water

The role of solvent hydroxyl functional groups on the interaction energy and growth of form I paracetamol crystal facets

The morphology of a crystal grown in a solvent can change depending on the solvent used during the crystallization process. Modification of the morphology of a crystal can be engineered based on information conferred by the functional groups of the facets of interest and the functional groups of the solvent. This study aims to predict the effect of the alcoholic functional group of amyl alcohol, benzyl alcohol, and phenol on the {002}, {011}, and {110} facets of Form I paracetamol. Prediction and simulation studies were carried out using an embedded tool available in Material Studio. The interaction between the solvents (phenol, benzyl alcohol, and amyl alcohol) and the surfaces used in this study revealed that the {011} facet had the most negative nonbonded energy, followed by the {110} and {002} facets. Overall, the nonbonded interactions between the solvents and the facets were dominated by Coulombic interactions, accounting for more than 90% of the energies, which is within the range from −2566 to −3613 kcal/mol. The binding energy for amyl and benzyl alcohols on the facets of the crystal, ranked from the strongest to the weakest, was in the order {002} > {110} > {011}, while for phenol, the rank was {002} > {011} > {110}. This result is in line with the observed crystal morphology of Form I paracetamol crystallized in a polar protic solvent, in which the most favorable solvent binding on the {002} facets delayed the growth of the elongated hexagonal morphology along the c-axis and formed prismatic-like morphology. Using benzyl alcohol as a case study, an assessment of synthon formation on facets {002} and {011} showed that synthon B is an important synthon for the growth of units of these facets, while synthon F is an important building block synthon for the {110} facet
