Abstract

Penelitian ini mengevaluasi efektivitas bubuk bambu yang diolah menjadi karbon aktif untuk meregenerasi minyak jelantah menggunakan tiga metode: tanpa perlakuan panas tinggi, aktivasi konvensional, dan aktivasi furnace. Aktivasi dengan KOH meningkatkan porositas dan luas permukaan. Parameter utama yang dianalisis meliputi kadar air, asam lemak bebas (FFA), dan bilangan peroksida (PV). Hasil penelitian menunjukkan bahwa arang aktif metode furnace memiliki kinerja terbaik, menghasilkan kadar air 0,05%, memenuhi SNI 7709:2019 (< 0,1 %). Sebaliknya metode konvensional dan serbuk bambu menghasilkan kadar air masing-masing sebesar 0,12% dan 0,66%. Kandungan FFA terendah sebesar 0,23 % juga terdapat pada arang aktif tungku memenuhi SNI 01-3741 2002 (<0,3%). Selain itu, bilangan peroksida yang dihasilkan arang aktif dengan metode furnace adalah 6,3 mek O2/kg, lebih baik dibandingkan metode konvensional (9,7 mek O2/kg) dan bubuk bambu (13,3 mek O2/kg), keduanya memenuhi SNI No. 01-3741-2013 (< mek 10 O2/kg). Kinerja arang aktif dengan metode furnace unggul disebabkan oleh porositasnya yang optimal, peningkatan kandungan karbon aktif, sifat hidrofobik, dan kemampuan interaksi dengan pengotor. Oleh karena itu, arang bambu yang diaktifkan dengan metode furnace menunjukkan potensi sebagai adsorben yang efektif untuk meregenerasi minyak jelantah.   This research evaluates the effectiveness of bamboo powder processed into activated carbon for regenerating used cooking oil using three methods: no high heat treatment, conventional activation, and furnace activation. The activation with KOH enhances porosity and surface area. Key parameters analyzed included water content, free fatty acids (FFA), and peroxide value (PV). The results indicated that furnace-activated charcoal performed best, yielding an oil content of 0.05%, which is compliant with SNI 7709:2019 (<0.1%). In contrast, conventional and bamboo powder methods produced water contents of 0.12% and 0.66%, respectively. The lowest FFA content of 0.23% was found in the furnace-activated charcoal, which meets the SNI 01-3741-2002 standard (<0.3%). Additionally, the peroxide value was 6.3 meq O2/kg, which is lower than the conventional method (9.7 meq O2/kg) and bamboo powder (13.3 meq O2/kg), both of which meet SNI No. 01-3741-2013 (<10 meq O2/kg). The furnace-activated charcoal's superior performance is attributed to its optimal porosity, increased active carbon content, hydrophobic properties, and interaction capabilities with impurities. Thus, furnace-activated bamboo charcoal shows promise as an effective adsorbent for regenerating used cooking oil.

Abstract

In Special Region of Yogyakarta, housing backlog is caused by supply and demand gap for mid-cost housing, limited capacity of developers, and low housing affordability for low-income people. This research aims to analyze the influence of social stratification on consumer preference for mid cost housing on housing developments and on non-clustered housing areas as well as the desired attributes of mid-cost housing. This research employed descriptive and inductive statistics with chi square test. Purposive sampling was employed with a sample size of 220 respondents were collected through interviews, questionnaires, observations, and literature review. The result show social stratification influences consumer preference for mid-cost housing on both areas. The desired attributes included location, physical characteristics, legal documents, neighborhood, and amenities. It is important for the local government to implement relevant policies and mortgage financing policies as well as provide supporting infrastructure and facilities for its development to ensure residential areas contribute to regional development.

Abstract

Background: Patients with chronic kidney disease (CKD) undergoing hemodialysis must adhere to fluid intake restrictions to prevent fluid accumulation, which can lead to complications such as edema, hypertension, and cardiovascular events. Excess intravascular and interstitial fluid volume contributes to fluid overload, a major risk factor for morbidity and mortality in this population. Objective: To describe adherence to fluid restriction among CKD patients receiving hemodialysis and identify common barriers to adherence. Methods: This descriptive survey study was conducted from January to June 2021 at two hospitals. A total of 129 CKD patients undergoing hemodialysis were recruited through purposive sampling. Inclusion criteria were age ?18 years, receiving routine hemodialysis for at least 3 months, and ability to communicate verbally. Fluid restriction adherence was assessed using the End-Stage Renal Disease Adherence Questionnaire (ESRD-AQ), previously validated and culturally adapted. Descriptive statistics summarized adherence patterns and patient characteristics. Results: Most participants were male, in late adulthood, had completed college, were unemployed, had been on hemodialysis for approximately 5 years, and underwent treatment twice weekly. Overall, 66% adhered to fluid restrictions, with 36.4% reporting following restrictions all the time. However, 62.8% indicated barriers to adherence, including lack of interest, inability to control fluid intake, and not understanding how to follow the restriction. Conclusion: While most CKD patients complied with fluid restrictions, a substantial proportion faced challenges that could undermine long-term outcomes. Continuous education, motivational support, and individualized counseling are essential to improve adherence. Future research should explore the association between adherence, fluid overload, and clinical outcomes.

Abstract

Chronic kidney disease (CKD) can cause changes in physical condition and cause cardiovascular problems to death. The development of CKD can be prevented by doing physical activity, one of which is aerobic exercise. Studies related to the effects of aerobic exercise on physical condition, especially in patients with chronic kidney disease, are still limited, so further studies are needed. The purpose of this study was to determine the effect of aerobic exercise on physical condition in patients with chronic kidney disease. The method used is a scoping review based on the PRISMA flow diagram. Article searches were conducted using electronic databases or internet searches, some databases used as article selection are ScienceDirect, Pubmed, and Springerlink. In conducting the search using the keywords "Aerobic Exercise" and "Chronic Kidney Disease" and "physical condition". Where in the screening or filtering of articles are given the filters "2020-2024", "Free full text" and "research article". The scoping review analysis was carried out using the Arksey and O'Malley theory approach which has been modified by Levac. From 4 databases, 6 articles were analyzed and focused on the effect of aerobic exercise on physical conditions in patients with chronic kidney disease. The results of the analysis showed that aerobic exercise significantly increased the SPPB (Short physical performance battery) value, increased the HRV (heart rate variability) index within the normal range, increased vagal activity leading to sympathovagal balance, improved systolic and diastolic values, increased physical activity levels, and decreased blood glucose and increased hematocrit.The effect of Aerobic exercise on the physical condition of patients is divided into physiological and biochemical effects. The effect of Aerobic exercise on physical conditions physiologically is to improve physical function, functional capacity and activity of the autonomic nervous system of the heart, increase blood flow, reduce risk factors for cardiovascular disease, increase cardiorespiratory capacity and muscle strength of the upper and lower body, and have a more comprehensive range in activities. The effect of Aerobic exercise on physical conditions biochemically is to maintain stable blood levels.

Abstract

Chronic kidney disease (CKD) is an incurable global health problem, with a growing prevalence, particularly in Asia. It is estimated that by 2030, 2.16 million individuals will require hemodialysis, a 233% increase from previous years. Self-care practices are an important aspect in improving health, preventing complications, and supporting daily functioning and well-being of patients. Therefore, a valid and reliable instrument is needed to measure the level of self-care in patients with chronic diseases. Objective to identify a validated self-care assessment instrument for hemodialysis patients. The methodological approach refers to Arksey and O'Malley, with article searches through ScienceDirect, PubMed, and EBSCO databases using relevant keywords, focusing on full-text, English-language, open access, and published in the last 18 years published between 2007 and 2024, keywords included "self-care", "hemodialysis", "instrument", "scale", and "chronic kidney disease". Of the 1,327 articles screened, the investigation was executed by accumulating empirical data from the preceding 18 years, aggregating 22 scholarly articles, among these, 9 articles satisfied the inclusion criteria, concentrating on selected studies that utilized quantitative methodologies and on self-care instruments for hemodialysis patients. The article evaluation was conducted systematically employing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) as a framework, succeeded by assessment based on inclusion and exclusion criteria. This study identified nine self-care instruments for hemodialysis patients with varying psychometric properties. Most of the instruments showed good reliability and validity, but still require improvement in criterion validation, sensitivity, and responsiveness. Future research should focus on the development of concise yet comprehensive instruments, cross-cultural adaptation, and full psychometric evaluation to ensure accurate measurement of self-care, thereby improving patients' health outcomes and quality of life.

Abstract

Chronic kidney disease (CKD) is a progressive condition that affects the quality of life of millions of people worldwide. While diet is essential in slowing disease progression and preventing complications, its implementation as self-care often faces barriers especially when patient preferences and context are overlooked. Most existing studies focus on clinical outcomes, with limited attention to how dietary practices are applied within a patient-centered approach that considers cultural, social, and psychological factors. This scoping review aims to map the existing evidence on how diet is implemented as a form of self-care in patients with CKD, within the framework of patient-centered care. This article uses three databases PubMed, EBSCO, and science direct with the keywords “diet,” “self care,” “self management,” and “chronic kidney disease” combined using Boolean AND and OR operators. Articles is in full text, in English, open access, published between 2015 and 2025, with quantitative, qualitative, descriptive, secondary analysis, quasi-experimental, or mixed methods research designs. From the 1,935 articles found, gradual screening was carried out until 7 relevant articles were obtained and further analyzed according to the PRISMA-Scr guidelines. Seven relevant articles showed that adherence to CKD diet was influenced by health literacy, self-efficacy, social support, and economic and cultural barriers. Experience-based interventions, goal setting, self-monitoring, and digital technologies such as health apps showed effectiveness in improving dietary adherence and patient quality of life. Collaborative approaches and family support were also shown to be important in strengthening the success of dietary interventions. Diet as part of self-care in CKD patients not only has clinical benefits, but also contributes to improving psychosocial well-being. A holistic approach that considers social, cultural, and emotional aspects is needed for dietary interventions to be more effective and sustainable in patient-centered practice.

Abstract

Owning residential property with ideal location, physical characteristics, neighborhood, legal documents, amenities, proximity to public services, etc., on a housing development requires consumers to have the ability and willingness to pay for such attributes. However, the cost is relatively high while the budget is often restricted. In Special Region of Yogyakarta, housing backlog is caused by supply and demand gap for mid-cost housing, limited capacity of developers, and low housing affordability for low-income people. This research aims to analyze the influence of social stratification on consumer preference for mid-cost housing on housing developments and on non-clustered housing areas (on which the houses are not constructed by a single developer) as well as the desired attributes of mid-cost housing. This research employed descriptive and inductive statistics with chi-square test. Test of independence was used to analyze the variables to determine whether social stratification influences consumer preference for mid-cost housing on both areas. Purposive sampling was employed with a sample size of 220 respondents. The result showed H0 was rejected as χ² = 12.35 > χ² α; (r-1)(c-1) = 5.991, meaning social stratification influences consumer preference for mid-cost housing on both areas. The desired attributes included location, physical characteristics, legal documents, neighborhood, and amenities. In order that residential areas may contribute to regional development, it is important for the local government to implement relevant policies and mortgage financing policies as well as provide supporting infrastructure and facilities for its development.
