Study of Tridax procumbens L. Extract on SOD and MDA levels in Cingarette Smoke Exposed Rats
No full textCigarette smoke is a source of free radicals that can damage cells and tissues of the respiratory tract. Tridax procumbens L. has potential as an antioxidant because it contains flavonoids that play a role in counteracting free radicals. The study aims to determine the potential of Tridax procumbens L. as a source of antioxidants against SOD and MDA levels in Wistar rats exposed to cigarette smoke. The study used Wistar rats (25 heads) with 5 treatments consisting of K (aquadest), KN (exposed to cigarette smoke), P1 (exposed to cigarette smoke and given 100 mg/kg BW extract), P2 (exposed to cigarette smoke and given 200 mg/kg BW extract), and P3 (exposed to cigarette smoke and given 300 mg/kg BW extract). Extract administration was carried out on days 1-21 and cigarette smoke exposure was carried out on days 8-21. Parameters observed consisted of flavonoid content test (by KLT method, total flavonoid content, total phenolic content), body weight, SOD levels (whole blood method), and MDA levels (TBARs method). Data were analyzed by one-way ANOVA test (P<0.05) followed by Duncan post hoc test. The results showed that Tridax procumbens L. contains flavonoids with an Rf value of 0.23. Body weight showed no significant difference (P>0.05), but SOD and MDA levels were different between treatments (P<0.05) with the most optimum dose of 300 mg/kg BW. The conclusion shows that a dose of 300 mg/kg BW of ethanol extract of Tridax procumbens L. can act as a natural antioxidant from exposure to cigarette smoke in vitro

Full text link
SMEs became the leading sector contribute to Gross Domestic Product (GDP) in Indonesia. The role of SMEs not only can give positive impact encourage potential development sectors. This paper is to investigate the relationship between the characteristics of regional specialization and labor productivity of small enterprises in the Food industry using the regency or city level data of South Sumatra from 2008-2018. The study used secondary data from the Department of Trade and Industry of South Sumatra for 17 regencies/cities in South Sumatra. Our study proceeds in two steps. First, we used Location Quotient (LQ) to identify the regional specialization. Second, we measured the impact of regional specialization on labor productivity including other regional variables; investment, a total of enterprises, size of employment, Gross Domestic Product Regional (GRDP), and Gross Enrolment Rate based on the panel data of regencies or cities. In the first step, we found that eight regencies specialized in the Food industry. Those typically concentrated near of big city where few enterprises dominate. Next, the LQ, investment, average size of employment, GRDP, and a total of enterprises have a significant effect on labor productivity while the education variable does not influence regional economic growth. According to this result, it should be cautioned that agglomeration may cause undesirable competition for raw materials leading to a detrimental result. This strongly suggests that to fully achieve labor productivity in South Sumatra, there is a need for the implementation of appropriate policy measure to overcome this issue.
Production and characterization of halal-based gelatin derived from Red Nile Tilapia (Oreochromis niloticus) fishbone
Full text linkGelatin is one of the chemical products derived from protein hydrolysis. The demand for gelatin in Indonesia increases yearly, but domestic production still needs to meet the demand, leading to imports. International gelatin production statistics indicate that 58% is derived from pig skin, which is prohibited for Muslims. Therefore, this research aims to produce halal-based gelatin that meets quality standards. Red Nile Tilapia (Oreochromis niloticus) fishbones are used as the raw material for this study, as their halal status is clear in the Quran and Hadith. The fishbones are soaked in different concentrations of phosphoric acid, namely F1 (4%), F2 (6%), and F3 (8%), for 48 hours, then extracted using distilled water solvent in a water bath for 6 hours. The extracted solution is filtered, and the filtrate is dried in an oven at 50°C for 48 hours. The gelatin yield is statistically analyzed using correlation methods, and its functional groups are identified using FTIR spectroscopy. Compared to existing standards, gelatin characteristics are evaluated through organoleptic tests, such as pH, gel strength, viscosity, moisture content, and ash content. The gelatin yield for F1 is 8.15 ± 0.18%; F2 is 12.08 ± 0.12%, and F3 is 15.66 ± 0.26%. The research demonstrates that phosphoric acid concentration significantly influences gelatin yield, with higher concentrations resulting in higher yields. The FTIR spectra also indicate that the synthesized gelatin resembles commercial gelatin in spectra and absorption peaks. All gelatin variations meet the requirements for organoleptic properties, gel strength, moisture content, and ash content, while only F1 and F2 meet the pH requirements.
Keywords: FTIR, halal gelatin, Red Nile Tilapia (Oreochromis niloticus) fishbone
Dielectric Characterization of Breast Cancer Cells using Split-Rectangular Ring Resonator Sensor
Full text linkExploring a universal method to enhance the performance of metamaterials by quantifying the impact of gap capacitance is an intriguing topic for many researchers. However, achieving this through conventional methods is extremely challenging. In this paper, we present a microwave sensor designed to characterize cancerous cells based on their electrical properties. The proposed design features a split rectangular ring resonator placed on a flame-retardant four (FR-4) substrate. The sensor aims to achieve high sensitivity and quality factors through the unique characteristics of the metamaterial structure in the GHz frequency range. Through simulations and experimental measurements, we demonstrate the sensor's effective capabilities in detecting cancer. The high sensitivity for both simulation and measurement, is estimated at 10 %. The simulations and validation confirm that this biosensor exhibits significant frequency shifts and high sensitivity. Our proposed configurations highlight the microwave sensor's potential for detecting six different breast cancer cell types: HSS-2, HS578-T_nm, MCF-2, MCF-10A_nm, T-47D, and T-47D_nm. Based on the existing literatures, the sensitivity of the proposed sensor is determined to be greater

Spatial analysis is useful for identifying areas of grouping or clusters of cases that indicate high risk areas so that prevention measures can be developed specifically in those areas. This study aimed to map and identify clusters of Coronavirus Disease cases in Kudus District. Method: An observational method with a case study design was conducted involving all confirmed cases of Coronavirus Disease from January to April 2021 in Kota Subdistrict, totaling 257 cases. Spatial analysis included overlay and buffering processed using ArcGIS, and clustering processed using SaTScan. Results: The study results showed that cases tended to be spread evenly across all villages, with the highest number of cases (8.2%) observed in Mlati Norowito Village. Spatial analysis revealed that the majority of cases were concentrated in villages with a population density of 8,001-12,000 people/km2 (51.7%) and villages with a number of social assistance recipients of 801-1,200 (36.6%), residing less than 250 meters from health care facilities (50.5%) and less than 250 meters from public facilities (59.14%), and four secondary clusters of Coronavirus Disease cases were identified. Conclusion: A higher cases of Coronavirus Disease were identified in villages with a high population density, a large number of social assistance recipients, close proximity to health care and public facilities, and four secondary clusters were identified
Anaemia and Caesarean Section in Caucasian Race: Assessment of Risk Factors and Management Strategies
Full text linkBackground: Anaemia among pregnant women is a significant public health concern, particularly in developing countries, due to its adverse effects on both maternal and fetal health. This study addresses the gap in research regarding anaemia in pregnant women in northern Iran, specifically among those undergoing elective caesarean sections. The objective is to assess the prevalence of anaemia in this population.
Method: This retrospective cross-sectional study included 719 Caucasian pregnant women who were candidates for elective caesarean sections from September 2020 to March 2023. Patient data was collected from hospital electronic records. Anaemia was defined as haemoglobin <10.5 g/L in the three months before delivery and under 10 g/L after delivery. The Chi-square test was employed to compare anaemia prevalence across different demographic groups, with a significance level set at p-value < 0.05.
Results: Among the 719 participants, key demographic findings revealed that most had primary education (26.8%), while only 12.4% held university degrees. Most (59.8%) resided in urban areas, with the largest age group being 31-36 (30.5%). Most women (75.2%) reported no history of miscarriage, and 98.2% experienced no bleeding during pregnancy. Notably, 57.7% of women reported no underlying health conditions; however, 9.2% had gestational diabetes, while others had blood disorders, neurological issues, or gastrointestinal problems. The prevalence of anaemia among patients undergoing elective caesarean sections was found to be 10.85%. Anaemia was more prevalent in women aged 25-30 years.
Conclusion: integrating nutritional counselling into routine prenatal care can help address dietary deficiencies before they contribute to anaemia. Moreover, collaboration between healthcare providers and community leaders may foster greater acceptance of health interventions. By tailoring educational programs to local contexts and addressing specific cultural beliefs about nutrition and health, policymakers can create more effective strategies to combat anaemia in pregnant women
Analysis of Public Sector Financial Performance With The Value For Money Approach In Bogor Regency
Full text linkFinancial performance is essential to ensure accountability and efLiciency in public sector organizations, especially in government. Public Sector Financial Performance requires assessment as a form of evaluation, so that Linancial performance becomes more optimal. The process of regional Linancial management consists of three stages: planning, implementation, and accountability, according to Minister of Home Affairs Regulation Number 13 of 2006 Concerning Regional Finavfc ncial Management Guidelines. The Financial Performance of the Bogor Regency Government in this study uses the Value for Money (VfM) approach with 3 (three) main factors, namely: Economic, EfLiciency, and Effectiveness of the 2014-2023 Fiscal Year. The Linancial reports produced have been in accordance with government accounting standards agreed upon by all parties involved, therefore used as a guideline to produce fair, clear, and complete Linancial reports to ensure transparency. The budget implementation report is a Linancial report that describes the future budget and budget allocation managed by the government during the reporting period. The Linancial performance of the Bogor Regency public sector is economical, with an average of 100.58%. However, efLiciency is still a concern, with an average of 99.21%, which needs more attention. The results of this analysis can be used as evaluation material for the Bogor Regency Government so that its public sector Linancial performance is more efLicient, so that the Bogor Regency Government can improve the quality of service to the community to be more optimal
Analysis of the Implementation of the Contractor Safety Management System (CSMS) in the Implementation Phase at PT X Ogan Komering
Full text linkThe high intensity of the project and stages of work at PT X Ogan Komering, so it requires contractors and subcontractors to operate in the area. Overall at PT X there are 70% of workers from contractors, so work accidents are more prone to occur in contractor workers, so it is important to ensure that contractors prioritize aspects of Occupational Safety and Health (K3). One approach to achieving this goal is to implement a CSMS, which ensures that contractors include OSH aspects in the project being undertaken. The implementation of CSMS often faces challenges, such as contractors' limited understanding of CSMS, for which efforts are needed to overcome these obstacles and prevent errors among workers that can cause incidents. The design of this study uses a descriptive qualitative method with a case study design with data collection from interviews, observations and document reviews. The Contractor Safety Management System (CSMS) consists of 2 Phases, namely Administration and Implementation, in the Implementation Phase consists of Pre-Work Assessment (PSB), Running Assessment (PB), and Final Assessment (PA). In general, the implementation of CSMS has gone well, this can be seen from the availability of SIKA, SIM-L and there is also Safety Induction as a step to minimize the risk of accidents. The supporting and inhibiting factor in the implementation of CSMS is the awareness of all parties involved. If awareness in the implementation of CSMS is lacking, its implementation will be hampered. The implementation of CSMS has been well underway and has succeeded in increasing OSH awareness and reducing work incidents, but it needs to increase supervision and socialization of contractor workers, especially in high-risk jobs
