Abstract

Carbon Nanotubes (CNTs) are nano-sized carbon that resembles tubes and has the potential to be used in various aspects of applications. Some of  the CNT carbon capture  methods include arc discharge, lasser ablation, CVD and electrodeposition. The advantage of the electrodeposition method is that the production cost is cheap and the preparation is easy. Electrodeposition is the precipitation of substances by using a direct electric current, with CO2 as the reactant. Factors that affect the growth rate of CNT are voltage, temperature, carbon source, electrode and time. The variation of the electorative time used was 60 minutes, 90 minutes, 120 minutes, 150 minutes, 180 minutes. The data collection process begins by shaping and measuring the weight of the electrode (Ni) with a diameter of 2 cm CNT deposition area. measuring the weight and melting Li2CO3 at a temperature of 750. then the CO2 flow rate setting, voltage setting  5V and time setting were then characterized by SEM-EDX and XRD. The results of the study showed that the optimal time obtained with a time of 120 minutes, the resulting CNT deposition rate was 1,618 g cm-2 h-1. Then based on the characterization of XRD and SEM, it shows that the longer the electrodeposition time, the less impurities are contained in the results obtained.

Data from the World Health Organization (WHO) in 2020 states that the number of diabetes mellitus patients has affected more than 500 million people, this number is expected to increase to 642 million (55%). In Indonesia, DM is the third largest case of death at 6.7% after stroke and CHD. DM control can be done with physical activity (diabetic foot exercise), because the permeability of the membrane to glucose increases when the muscles contract because muscle contractions have insulin-like properties. Objective: To determine nursing care for people with diabetes mellitus with foot exercise therapy nursing interventions at Class II-A Women's Prison Bandar Lampung. Method: The design of this scientific paper uses a descriptive design. The data collection method in this scientific paper uses interviews, observation and the application of foot exercises to patients managed by Mrs M and Mrs H. Results: It was found that diabetic foot exercise can reduce blood glucose levels where Mrs M with current blood sugar pretest was 320 mg/dl and decreased to 120 mg/dl in the posttest. Whereas in Mrs H with current blood sugar pretest 240 mg/dl decreased to 120 mg/dl in the posttest. Conclusion: Diabetic foot exercise can reduce blood glucose levels. Suggestion: It is hoped that the results of this study can increase the knowledge of people with diabetes mellitus about foot exercises in reducing and controlling blood glucose levels. Keywords: Foot Exercise Therapy; Patients with Diabetes Mellitus; Lowering Blood Glucose Levels Pendahuluan: Diabetes mellitus (DM) merupakan salah satu masalah kesehatan dunia.

ABSTRACT Interest is a factor that motivates individuals to pursue what they desire. Currently, there is a low level of adolescent interest in participating in adolescent health services, with only 51 out of 422 adolescents in Kalirejo Village attending these services. This low participation can be influenced by various factors such as knowledge, skills, and attitudes. Knowledge forms the foundation of behavior, and according to Nasution & Manik (2020), adolescents' knowledge about reproductive health remains low. In Kalirejo Village, only 9 out of 30 adolescents, or approximately 30%, have a clear understanding of reproductive health, while the remaining 70% do not. To determine the relationship between adolescents' knowledge of reproductive health and their interest in participating in adolescent health services in Kalirejo Village, Negri Katon Subdistrict, Pesawaran District in 2024. This study employs a quantitative research design using an analytical survey with a cross-sectional approach. The population includes all adolescents in Kalirejo Village, comprising 7 hamlets with a total of 422 adolescents, and the sample is 80 respondents. The sampling technique used study is purposive sampling. In this study, the majority of respondents were mid-adolescents aged 16-20 years (48.6%), with the predominant gender being female (55%) and the highest education level being high school (63.8%). The results indicated that adolescent knowledge about reproductive health was low (50.0%) and interest in participating in adolescent health services was also low (46.2%). The p-value analysis was 0.001 (<0.05), indicating a significant relationship between adolescents' knowledge about reproductive health and their interest in participating in adolescent health services. Suggestions to the health center spread the information about integrated health care center activities to all adolescents in order to interset in participating adolescent healthcare. Keywords: Interest, Adolescent Health Services, Knowledge, Reproductive Health.  ABSTRAK Minat merupakan suatu hal yang mendorong seseorang untuk melakukan apa yang mereka inginkan.

Abstract

This research optimizes the preparation parameters of palm oil-based nanofuel and Multi Wall Carbon Nanotube (MWCNT) to produce stable nanofuel. The parameters optimized include stirrer speed, sonication time, sonication power, and surfactant ratio, with stability measured through absorbance and sedimentation ratio (SR). The Taguchi method, using an L9 orthogonal array designed with minitab 19.0 software, was employed for single-objective optimization, while Grey Relation Analysis (GRA) is applied for multi-objective optimization. Experimental results show that the optimal conditions for absorbance are stirrer speed of 1000 rpm, sonication time of 30 minutes, sonication power of 200 watts, and surfactant ratio of 1, whereas for sedimentation ratio the optimal conditions are stirrer speed of 1000 rpm, sonication time of 30 minutes, sonication power of 150 watts, and surfactant ratio of 1. ANOVA analysis reveals that surfactant concentration contributes the most to nanofuel stability, with contributions of 79.63% for absorbance and 82.60% for sedimentation ratio. Multi-objective GRA optimization results also show that surfactant concentration is the most dominant factor, contributing 71.5% to the Grey Relational Grade (GRG). The consistency of optimal parameters yielded by both Taguchi and GRA methods reinforces the validity and consistency of this study's results. This research provides a strong foundation for the development of more stable nanofuels, potentially enhancing energy efficiency and sustainability. These findings offer practical guidelines for real-world applications and make significant contributions to nanofuel technology

Abstract

Anodization is a critical electrochemical process for producing titanium oxide layers with varying characteristics, significantly influencing the physicochemical properties, biocompatibility, and performance of bone implants. This study systematically reviews the current state of research on the effects of anodization parameters and silver coatings on the morphology, functional groups, and phase identification of Ti-6Al-4V bone implants. By synthesizing findings from 18 relevant studies selected from 1044 screened articles (2000–2023), this review provides a comprehensive framework for understanding the role of anodization and silver coating in improving implant performance. The review highlights how variations in anodization parameters—such as electrolyte composition, voltage, and duration—significantly impact critical implant properties, including corrosion resistance, antimicrobial efficacy, and biocompatibility. Additionally, silver coatings are underscored for their antimicrobial benefits and ability to address challenges such as bacterial adhesion and biofilm formation. Beyond functional improvements, this review identifies gaps in the literature, such as the limited exploration of process optimization and the environmental implications of implant fabrication, offering actionable insights for future research. The novelty of this article lies in its holistic synthesis of fragmented findings, bridging material science, biomedical functionality, and sustainability. It provides a structured evaluation of key process parameters and their influence on implant performance, emphasizing the need for balanced approaches that integrate clinical effectiveness with environmentally responsible practices. By offering a unified perspective, this review serves as a valuable reference for advancing both research and practical applications in the development of high-performance bone implants.
