AbstrakHipertensi adalah peningkatan tekanan darah sistolik ≥140 mmHg atau tekanan darah diastolik ≥90 mmHg. Penyakit ini disebut juga the silent killer karena tidak menunjukkan gejala. Salah satu faktor penyebab hipertensi adalah tingginya asupan natrium dan rendahnya asupan kalium. Rasio Na:K yang dianjurkan adalah 1:1. Penelitian ini bertujuan untuk mengetahui perbedaan asupan natrium dan kalium pada penderita hipertensi dan normotensi masyararakat Etnik Minangkabau di Kota Padang. Desain penelitian study comparative dengan pendekatan cross sectional. Populasi adalah masyarakat etnik Minangkabau usia 35-65 tahun di 4 kecamatan terpilih di Kota Padang. Jumlah sampel sebanyak 254 orang yang diambil secara multi stage random sampling. Data responden dikumpulkan dengan kuisioner, tekanan darah dengan sphygmomanometer, asupan natrium dan kalium dengan food frequency questionnaire (FFQ). Data dianalisis dengan uji Chi-Square pada p-value< 0,05 dan uji beda rata-rata dengan metode Independent sample t-test. Hasil penelitian didapatkan rerata sistolik pada normotensi 118,87 mmHg dan diastolik pada normotensi 76,74 mmHg. Rerata sistolik pada hipertensi 154,50 mmHg dan diastolik pada hipertensi 90,59 mmHg. Tidak ditemukan adanya hubungan antara asupan natrium, asupan kalium dan rasio asupan Na:K dengan tekanan darah. Kesimpulan penelitian ini ialah tidak ada hubungan antara asupan natrium, asupan kalium dan rasio asupan Na:K dengan tekanan darah.Kata kunci: natrium, kalium, rasio Na:K, tekanan darah, normotensi, hipertensiAbstractHypertension is the blood pressure escalation of systolic ≥140 mmHg or diastolic ≥90 mmHg. This is also called the silent killer because it does not show any symptoms. One of the factors causes hypertension is high sodium and low potassium intakes. The ratio of Na:K that is suggested is 1:1. The objective of this study is to know the differences sodium and potassium intake in patients hypertension and normotension on Minangkabau Ethnic society in Padang. The design of this research was comparative study with the cross sectional approach. The population were taken from Minangkabau ethnic age 35-65 years old in four selected districts in Padang. The total sample of 254 people were taken by multi-stage random sampling. The data were collected by questionnaire of respondents, sphygmomanometer blood pressure, sodium and potassium intakes with a Food Frequency Questionnaire (FFQ). The data was analyzed by Chi-Square test at p-value <0.05 and an average of different test methods Independent sample t-test. The result showed that average systolic of normotensive was 118.87 mmHg and diastolic of normotensive was 76.74 mmHg. The average sistolic of hypertension was 154.50 mmHg and diastolic of hypertension was 90.59 mmHg.

Background: Basic immunization is a mandatory health program held by the government for infants aged 0-12 months as immunity against diseases that can be prevented by immunization. The results of the initial data tracing at the Jeulingke Health Center in Banda Aceh City in 2019, showed that one village had reached the UCI, namely 20% and 80% of the villages had not yet reached the UCI. The aim of this study was to determine the factors that influence the completeness of complete basic immunization in infants in achieving Universal Child Immunization (UCI) in the working area of the Jeulingke Health Centre, Banda Aceh in 2020. Methods: This study is a descriptive analytic study with a cross sectional design. Sampling using proportional sampling method as many as 81 mothers who have babies 9-12 months. Data analysis used the Chi Square test. Results: The results showed that infants who were given complete immunization were 45.7% and those who were incomplete were 54.3%. The bivariate analysis showed that there was a relationship between knowledge (p-value 0.001), family support (p-value 0.001), the role of health workers (p-value 0.025), and the issue of illicit immunization (p-value 0.046) with the completeness of basic immunization in infants. Conclusion: It is hoped that Puskesmas officers can conduct counseling in the community to increase mother's knowledge about the benefits of complete basic immunizations for babies and it is hoped that mothers should immunize their children on time, considering that immunization is very important to equip their children with health in the future.

Tapai is a snack produced from the fermentation process of carbohydrate food as a substrate by yeast. Tapai is a hitz snack with a variety of creations. Each region has potential that can be developed into superior products in that area. These superior products must be continuously developed so that they will become great. The development of this superior product will certainly support the development of the local economy of the area concerned. Local economic development will also support the community concerned to develop. Local economic development that is based on superior products cannot be carried out by entrepreneurs alone, there needs to be a relationship from the government and other stakeholders engaged in local economic development. Government support is certainly needed by making policies that support superior product development policies. Meanwhile, other stakeholders assist entrepreneurs in developing their products so that they can be developed and known outside the region.

This study aimed to optimize the production of Manganese Peroxidase (MnP) enzyme from Pleurotus ostreatus using agricultural waste substrates such as coffee grounds (CG) and rice bran (RB) through Response Surface Methodology (RSM) approach. Optimization was conducted using a Central Composite Design (CCD) with three main variables, namely MnSO₄ concentration (0.5-1.5) mM, incubation temperature (25-35) °C, and reaction time (20-30) min. The enzyme fractionation process was carried out by ammonium sulfate saturation (0-20%), (20-40%), (40-60%), followed by dialysis, and SDS-PAGE analysis. The results showed that the 0-20% fraction of CG:RB (50:50) substrate had the highest enzyme activity, which was 20.588 ± 0.141 U/mL, with the highest specific activity of 76.967 ± 0.325 U/mg. The highest protein content was found in CG:RB (0:100) substrate at 0.825 ± 0.016 mg/mL. However, the enzyme activity was lower due to the presence of non-enzymatic proteins and natural inhibitors. This study successfully demonstrated that the substrate combination of CG:RB (50:50) provided optimal results for MnP production. The Response Surface Methodology proved effective in optimizing process variables, providing great potential for biotechnology applications using agricultural waste as an environmentally friendly raw material.Keywords: Pleurotus ostreatus, Manganese Peroxidase, Coffee Dregs, Rice Bran, RSM, SDS-PAGE

Due to growing interest in renewable energy technologies, dye-sensitized solar cells (DSSCs) have emerged as promising alternatives to conventional photovoltaics. This study explores the enhancement of titanium dioxide (TiO2) photoelectrodes through doping with lanthanum (La), a rare earth element known for its ability to modify semiconductors' structural and electronic properties. La-doped TiO2 was synthesized using the sol-gel method with La concentrations ranging from 0 to 4 mol%. The resulting films were deposited onto substrates and sintered at 600 °C for 1 hour. Characterization techniques included X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS), UV-Vis spectrophotometry, and Fourier-transform infrared spectroscopy (FTIR). XRD confirmed the anatase phase of TiO2 and the appearance of La2O₃ phases with doping. The smallest crystallite size (8.20 nm) and lowest bandgap energy (3.31 eV) were achieved at 1 mol% La, compared to 3.52 eV for undoped TiO2. SEM-EDS indicated uniform La distribution, while FTIR revealed changes in surface chemistry. These results suggest that La doping, particularly at 1 mol%, can effectively enhance the optical and structural properties of TiO2, making it a promising candidate for improved DSSC performance.
