ABSTRACT. This study is performed to investigate the characteristics of intrusive andesite rock consisting of Kalirejo Road Side Slope located in Kulon Progo Mountains. The rocks consisting the slope are identified by visual observation of hand specimens in the field, petrographic and X-ray Diffraction (XRD) analyses of the rock samples in the laboratory, upon which genetic rock classification is determined. The altered rock types are determined by the presence of specific minerals identified in the petrographic and XRD analyses. The alteration intensity is examined by comparing the amount of secondary minerals to the primary minerals observed in the petrographic and XRD analyses. The developments of rock weathering are determined in the field GSI classification based on the visual characteristics and in the laboratory-based on the Chemical Index of Alteration (CIA) and engineering properties of the altered rocks. The results show that the rocks typically consisted of 33.2 to 59.2% plagioclase, 1.4 to 5.1% quartz, therefore, are classified as andesite. The presence of halloysite, montmorillonite, and kaolinite as secondary minerals in the altered andesite indicated that the parent andesite rocks have undergone argillic alteration. Meanwhile, the percentages of primary minerals to secondary minerals indicate that the andesite rocks have undergone moderate to high alteration intensity. Based on the visual characteristics, the research area consisted of fresh, slight weathered andesite rocks and complete weathered residual soil. The CIA values of the samples are increased with the increase in rock weathering. Identification of visual characteristics of rock weathering appeared to be in good agreement with those classified based on the CIA and engineering properties analysis results. The uniaxial compressive strength (UCS) of rocks and soils is determined by point load tests. Engineering properties of the residual soils are performed by using ASTM standard procedures. In the lower part of the roadside, slope consists of fresh and slightly weathered andesite rocks, which have relatively high strength and are classified as medium strong rocks. Meanwhile, the upper part of the slope profile contained completely weathered residual soil, which had very low compressive strength, are classified as very weak soil.Keywords: andesite, argillic alteration, Geological Strength Index (GSI), hydrothermal alteration, roadside slope, weathering

Introduction: Assessing the risk of undernutrition in hypertensive diabetics is essential. It makes it possible to detect undernutrition for better care. The objective of our study is to describe the factors influencing this undernutrition.
Methods: A descriptive study was conducted on a sample of 366 diabetics with hypertension and 326 with normo-glycemic hypertension aged 50 years and over. Patients were enrolled at the University Hospital in Tlemcen from January to June 2018. The data collection was carried out using a questionnaire: The MNA (The Mini Nutritional Assessment).
Results: The study made it possible to establish the profile of subjects at high risk of undernutrition. In our sample, age was not correlated with risk of malnutrition in diabetic hypertensives and normo-glycemic hypertensives respectively (p = 0.304 and p = 0.444). The linear regression model uses gender as an age-independent factor that affects the risk of undernutrition (p = 0.001). BMI was one of the most relevant variables for predicting the occurrence of undernutrition (p = 0.000). Thus, diabetic hypertensive patients in our study who were treated with an Angiotensin II receptor blockers , an angiotensin converting enzyme inhibition or an ARB/diuretic combination were more at risk of undernutrition (p = 0.009, p = 0.026 and p = 0.013).
Conclusion: Particular attention should be paid to diabetic hypertensive subject. The treatment of hypertension in diabetics aggravates this malnutrition. Thus, a nutritional status assessment should be established in any diabetic hypertensive patient allowing appropriate therapeutic management to avoid all complications associated with undernutrition.

Published: January 2021

The objective of the present study was to develop and evaluate bi-layer tablets of Ketorolac tromethamine, a nonsteroidal antiinflammatory drug with short half-life, that are characterized by initial burst drug release in the stomach and comply with the release requirements of sustained-release products. Each of the proposed bi-layer tablets is composed of an immediate-release layer and a sustained-release layer, anticipating rapid drug release that starts in the stomach to rapidly alleviate the symptoms and continues in the intestine to maintain protracted analgesic effect. Gastro retentive Bi-Layer tablets of Ketorolac Tromethamine were prepared by using hydrophilic polymers with direct compression on floating – matrix technology and evaluated. Ketorolac tromethamine is freely soluble in water, so it is suitable to develop it as gastro retentive bi-layer tablets using hydrophilic polymers. The developed formulation is equivalent to calculated theoretical drug profile in view of its in vitro release. Immediate release layer was prepared by using dry granulation method in which ac-di sol used as a disintigrant for immediate release of drug. Sustained release layer formulated by using HPMC as release retardant, two grades of HPMC that are HPMC K4M and HPMC K100M used to get sustained release profile for 24 hr. Various trial batches are taken to get desired release profile. Ketorolac tromethamine release from the developed floating formulation followed Higuchi model and nonFickian diffusion is found to be the main mechanism of drug release. The manufacturing procedure was found to be reproducible and formulations were stable after one month of stability studies.

Published: January 2021

Indonesia has been placed as the world's first producer of crude palm oil and crude palm oil. In producing crude palm oil (CPO) and palm kernel oil (PKO), the palm oil industry relies heavily on processing fresh fruit bunches (FFB) at palm oil mills (POM) and is traded internationally. However, this process also produces solid organic waste [ i.e. empty bunches (EFB)], which reach up to 25 %% of FFB. The analysis shows that the application of empty bunches as organic fertilizer has not been able to increase the amount of nutrients in palm oil leaves and increase palm oil production. Application of palm oil mill effluent which is able to increase the amount of nutrients in palm oil, especially nitrogen and phosphate, and a positive impact to increase the production of oil palm plantations, especially on productivity (tons / ha).
