Abstract

This study reports the synthesis and evaluation of a biodegradable slow-release fertilizer based on microcrystalline cellulose (MCC) extracted from coconut husk waste from Seluma Regency, Bengkulu Province. MCC was prepared through sequential acid washing, alkaline delignification, bleaching, and acid hydrolysis. A composite fertilizer was synthesized by incorporating maleate-containing polymer segments into MCC through limited radical grafting and/or esterification, followed by incorporation of polydihydroxymethylurea potassium phosphate (PDMU–KP) using citric acid as an interaction agent. Fourier transform infrared (FTIR) analysis indicates the presence of carbonyl, amide, and phosphate-related functional groups associated with the composite structure. Scanning electron microscopy (SEM) revealed a dense and agglomerated composite morphology with a rough, layered surface and crystalline aggregates, while energy-dispersive X-ray (EDX) analysis verified the presence of C, N, O, P, and K elements within the copolymer matrix. X-ray diffraction (XRD) analysis showed a reduction in cellulose crystallinity after copolymerization, indicating the formation of a polymer composite. Nutrient release tests conducted in distilled water for 28 days demonstrated controlled and differential release behavior governed by polymer swelling and matrix relaxation processes. Phosphate exhibited a maximum release concentration of 0.398 mg/L on day 7, followed by a gradual decrease to 0.058 mg/L by day 28. In contrast, nitrogen release occurred more gradually, reaching a maximum concentration of approximately 3.08 mg/L on day 14 before declining at later stages. These results indicate that the MCC-g-PMA/PDMU–KP copolymer provides sustained nutrient release with distinct release maxima for phosphorus and nitrogen, highlighting its potential as a cellulose-based slow-release fertilizer designed to improve nutrient use efficiency and reduce nutrient losses, derived from locally available coconut husk waste.

Abstract

Chronic kidney disease (CKD) is a progressive and irreversible impairment of kidney function that disrupts fluid and electrolyte balance in the body. One of the renal replacement therapies for is hemodialysis. However, this procedure may lead to metabolic complications, including alterations in blood glucose levels, both in diabetic and non-diabetic patients. This study aimed to determine the profile of random blood glucose levels in Chronic kidney disease patients after undergoing hemodialysis. This descriptive study used a cross-sectional approach and was conducted at Harmoni Laboratory, Pekanbaru, in March 2025. A total of 30 were selected using sampling. Blood glucose levels were measured using the Glucose Oxidase-Peroxidase Aminoantipyrine Phenol (GOD-PAP) method. The results showed that 7 respondents (23.3%) had low glucose levels, 6 respondents (20%) had high levels, and 17 respondents (56.7%) had normal glucose levels. The average random blood glucose level was 116.1 mg/dL. Age and gender influenced glucose levels, with the majority of abnormal values found in male patients and those aged 41–70 years. In conclusion, most CKD patients after hemodialysis had random blood glucose levels within the normal range, although some exhibited low or high levels.Keywords: Random Blood Glucose, Chronic Kidney Disease, Hemodialysis
