Sclerosis Lipogranuloma, also known as penile paraffinoma, is a skin reaction that occurs after the injection of paraffin or mineral oil into the penis, which is done to enlarge the size of the penis. In this study, a minor procedure was used, is a medical technique that involves implanting the penis into the scrotum to provide skin coverage and vascularization for the penile shaft. The advanta…
Jejunoileal Atresia (JIA) is a congenital disorder that involves obstruction in the jejunum and ileum of the neonatal small intestine, requiring immediate treatment. The prevalence of JIA worldwide ranges from 1 in 5,000 to 1 in 14,000 live births. JIA can be caused by several risk factors, such as low birth weight (LBW), prematurity, male gender, genetic factors, maternal infections during pre…
Burn is skin injury due to contact with heat and one of the major global public health problems. Most of burn pastients end up infectious complications and mortality rate higher in burn patients with infection. This study aims to determine the bacterial patterns and antibiotic resistance in burn patients at Arifin Achmad Hospital Riau Province for the period of January 2022 – December 2023. T…
Jejunoileal Atresia (JIA) is a rare congenital anomaly and a common cause of intestinal obstruction in neonates, characterized by stenosis in the jejunum and ileum, especially in preterm infants. This congenital anomaly typically arises from vascular disruption and abnormal development of the intestinal segment during the intrauterine period. The global incidence of JIA ranges from 1:5000 to 1:…
ABSTRACT Indonesian Sustainable Palm Oil (ISPO) is a standard for sustainable palm oil plantations in Indonesia. Presidential Decree Number 44 of 2020 regulates that every company and independent smallholder in Indonesia must have ISPO certification no later than 2025. Minister of Agriculture Regulation Number 38 of 2020 in article 53 states that growers can apply for assistance with ISPO cert…
This research aims to analyze peat soil electrical conductivity and impedance values using the four point probe method. Peat soil samples were taken from locations with a depth of 20 cm from the surface. Electrical conductivity measurements were performed using the four point probe method with brass wire with a length of 5 cm as electrodes. The results showed that the electrical conductivity o…
The quality of Crude Palm Oil (CPO) can be determined through the assessment of beta-carotene content in Fresh Fruit Bunches (FFB) of oil palm. This study aims to utilize an LED-based multispectral imaging system to predict the beta-carotene content in FFB. The imaging system employs eight LED wavelengths (680 nm, 700 nm, 750 nm, 780 nm, 810 nm, 850 nm, 880 nm, and 900 nm) as light sources. A P…
This study aims to fabricate Dye-Sensitized Solar Cells (DSSC) based on ZnO nanorods by enhancing their efficiency through titanium (Ti) doping in the active ZnO material. It also investigates the effect of varying the growth time of ZnO nanorods on DSSC efficiency. Ti-doped ZnO nanorods were successfully synthesized using a seed-mediated hydrothermal method with variations in growth time. The …
The identification of full and empty palm fruit bunches after threshing plays an important role in improving the oil extraction rate (OER) in palm oil mills. Undetected filled palm fruit bunches after threshing can reduce extraction efficiency and lead to oil loss cases. Manual assessment is often slow and inaccurate, so a faster and more effective technology is needed. This study uses computer…
