Abstract

Environmentally friendly construction development of sustainable and economical building materials. Geopolymers are increasingly in demand, by utilizing waste. Waste materials that mostly contain silicon (Si) and aluminium (Al) are the source materials for making geopolymers. Geopolymers are artificial polymer composites that are environmentally friendly sustainable products. Fly ashas a binder in geopolymers, its physical and chemical characteristics help the geopolymerization reaction. High content of alumino silicate in alkaline. Sustainable building material construction combines industrial and agricultural waste in the form of activated carbon of palm shells. The use of waste materials solves the problem of waste disposal and minimizes the demand for natural resources for mortar production. This study produces geopolymer mortar using fly ash as a substitute for cement and activated carbon of palm shells as a substitute for sand.

Abstract

Introduction: Soil-transmitted helminth (STH) infections remain a significant public health concern in Indonesia, particularly among children living in suboptimal sanitation environments. Children with disabilities, especially those exhibiting symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD), are theoretically considered more vulnerable to STH infection because of behavioral factors that may interfere with personal hygiene. However, epidemiological data on STH infections in this population in Bengkulu City are limited. Methods: This descriptive cross-sectional study was conducted among students with disabilities enrolled in special schools (Sekolah Luar Biasa) in Bengkulu. A total of 70 students were selected using proportional stratified random sampling method. ADHD symptoms were assessed using the Indonesian Hyperactive Child Behavior Assessment Scale (SPPAHI), which was completed by parents or guardians. Stool samples were collected and examined for STH infections using the Kato–Katz technique. Results: All 70 stool samples examined were negative for STH infection, indicating a prevalence of zero. Based on the SPPAHI assessment, 56 students (80.0%) were identified as having ADHD symptoms, while 14 students (20.0%) were classified as suspected ADHD. Conclusion: No STH infection was detected among students with disabilities or ADHD symptoms in special schools in Bengkulu City. This zero prevalence may be associated with enhanced parental supervision, limited exposure to high-risk environments, and the effectiveness of the national mass drug administration deworming program in the country.

Abstract

This narrative review seeks to critically analyze the efficacy of albendazole, the cornerstone anthelmintic of the program. Relevant literature (2020-2025) was identified through a systematic search of the ScienceDirect and Google Scholar databases. While evidence confirms albendazole's effectiveness, with cure rates up to 93%, its performance is inconsistent and influenced by a confluence of factors. A critical constraint identified is the absence of robust, large-scale national surveillance data on STH prevalence and drug efficacy, hindering a comprehensive assessment of albendazole's performance within the program. The persistent burden of STH underscores a gap between program implementation and its intended public health impact. While albendazole remains essential, its variable efficacy and operational barriers necessitate a critical reassessment of the current strategy.
