Water has good quality if it is in accordance with several parameters, including chemical, physical, and biological parameters. Mineral salt content is one of the chemical parameters that can be used to determine the quality of water. In this study, the synthesis of cassava peel hydrochar was successfully carried out using the hydrothermal carbonization (HTC) method. This material was developed to reduce waste of cassava peel biomass and overcome the problem of water hardness. HTC cassava peel was developed as an alternative hard water softener adsorbent. The results of FTIR characterization on hydro-activation (activating hydrochar) and hydro-non (non-activating hydrochar) contain functional groups of O-H stretch, C-H stretch, C≡C stretch and C=C stretch. Observation of surface morphology by SEM method on hydro-non in the form of large sheets, while the surface on hydro-activities in the form of small sheets. The adsorption capacity of hydro-active against Ca2+ ions and Mg2+ ions were 85.240 mg/g and 87.210 mg/g, respectively. Meanwhile, the hydro-non adsorption capacity of Ca2+ and Mg2+ ions were 84,736 mg/g and 85,713 mg/g. The kinetics of hydro-active adsorption on Mg2+ ion took place on order 3 (0.000003 min-1) while when adsorption of Ca2+ ion took place on order 0 (0.0324 min-1).©2021 JNSMR UIN Walisongo.

More than 50% of cases of anaemia are spread throughout the world. One of checks to diagnose anaemia is examination of haemoglobin levels. Examination of haemoglobin levels can be determined by several methods, namely the Sahli’s method, the Cyanmethemoglobin method manually and by automatic method. Examination of haemoglobin levels with a of more than 5 minutes incubation time leads to inaccurate results. The purpose of this research is to determine the effect of incubation time on the results of haemoglobin level examination of the Cyanmethemoglobin method. This type of research is experimental research to determine the effect of the incubation time on the results of haemoglobin level examination of the Cyanmethemoglobin method. The population in this research is outpatients with a diagnosis of kidney failure at Gatoel Hospital, Mojokerto, in March 2019. The number of examination samples is 9 samples which is carried out at the Gatoel Hospital Laboratory, Mojokerto. The results of this research show that the average haemoglobin incubation rate of 5 minutes is 7,52 g/dl, incubation of 20 minutes is 7,18 g / dl, and incubation of 30 minutes is 7,04 g / dl.

This disease can attack someone with a weak immune system. Pneumonia is inflammation of the lungs that can be caused by pathogens, such as bacteria, viruses, and fungi. The purpose of this study was to classify fungal pneumonia, bacterial pneumonia, and lipoid pneumonia based on texture characteristics and the MLP method using machine learning WEKA. The method in this study has three stages including pre-processing, extraction of texture features consisting of Histogram and GLCM, and classification using the MLP (Multi Layer Perceptron) method. The results of the texture feature extraction showed that the three types of pneumonia were: lipoid pneumonia with brightness, sharp contrast random distribution on correlation characteristics, bacterial pneumonia with high brightness, high contrast random distribution on energy characteristics, and fungal pneumonia with brightness, sharp contrast, random distribution of homogeneity attributes. The third similarity of pneumonia is in the gray level that collects each other in the middle. The method used in this study resulted in the same accuracy, sensitivity, and specificity, namely 100%. The image classification in this study shows the success of the texture features and the MLP method in classifying pneumonia images accurately so that they can be used as additional tools that make it easier for medical experts. ©2020 JNSMR UIN Walisongo.
