Abstract

Cataract is an opacity of the lens that causes a progressive decrease in visual acuity. Cataracts are the leading cause of blindness in the world and can be caused by many factors. This case report aims to identify and recognize the symptoms of cataract and appropriate management in a patient with traumatic cataract. A 54-year-old male patient came to the Eye Polyclinic of Dr. Zainoel Abidin Regional General Hospital Banda Aceh with complaints of blurred vision in the left eye like a fog that has been felt since 8 months ago after an accident and the left eye was hit by a motorcycle handlebar where the patient felt the complaint worsened in the past 2 months. Initially the patient felt glare when looking at light or car lights at night. On ophthalmologic status examination, it was found that the OS visus was 1/300 and the OS lens was cloudy. The patient was diagnosed with traumatic cataract OS ec blunt trauma. The management performed on the patient was lens extraction using the small incision cataract surgery (SICS) method and intraocular lens (IOL) insertion. The patient's vision improvement after cataract surgery was 5/24 at the first follow-up, 5/18 at the second follow-up, 5/9 at the third follow-up and there were no other ocular abnormalities due to trauma.

Abstract

Hand hygiene is an important factor that needs to be observed in controlling the spread of diseases transmitted through hand-to-hand contact. Synthesis of silver nanoparticles from tembelekan (Lantana camara) and paku laut (Acrostichum aureum) using the green synthesis method has good antibacterial activity against Staphylococcus aureus and Escherichia coli bacteria. Therefore, a preparation formulation was made, namely hand sanitizer, which is still rarely used. Formulations that have successfully entered the evaluation stage include organoleptic tests, homogeneity tests, spreadability tests, adhesion tests, viscosity tests, pH tests, accelerated stability tests, and irritation tests. Antibacterial activity was evaluated against bacteria Staphylococcus aureus and Escherichia coli. The hand sanitizer is formulated to contain 5% tembelekan AgNPs (F1); paku laut AgNPs 5% (F2); and a combination of 2.5% paku laut AgNPs and 2.5% tembelekan AgNPs. The resulting hand sanitizer has good organoleptic characteristics, except for the color of the preparation, which changed during the accelerated stability test. Test results for pH, adhesion, spreadability, viscosity, and homogeneity of hand sanitizer meet the requirements of a good test. Irritation tests on ten volunteers showed no irritation reaction. Antibacterial tests show that hand sanitizer has bacterial antibacterial activity with an average ± standard deviation of the inhibition zone Staphylococcus aureus is 6.605±0.459(F1); 6.665±0.615(F2); 6.380±0.282(F3) dan Escherichia coli namely 6.575 ± 0.219 (F1); 6.860 ± 0.155 (F2); 6.810 ± 0.056 (F3). Making hand sanitizer AgNPs-based ingredients from plants can be used as hand sanitizer, but stabilizers are required to prevent color changes during storage.

Abstract

The Gayo tribe in Lesten Village has historically relied on plants to fulfill their nutritional needs. Expanding knowledge about diverse plant-based food sources offers a promising strategy for addressing future food insecurity. A dependence on conventional plant species has often resulted in inadequate food supplies, highlighting the need for alternative approaches that incorporate a broader range of plant resources to mitigate food scarcity. Located within the Leuser mountain buffer landscape, Lesten Village in Gayo Lues Regency, Aceh Province, represents a key agricultural area with significant potential to benefit the local community. This study aimed to document and analyze the plant species used as food sources by the Lesten Village community. Data collection combined qualitative and quantitative methods, including exploration, direct observation, and semi-structured interviews. The results revealed that female respondents had a higher level of knowledge about plant use as food sources. Notably, 52.9% and 55.7% of these respondents were aged 50 years or older. The community in Lesten utilized a total of 51 plant species from 26 families as food ingredients. Vegetables constituted the largest category (34%), followed by spices (30%), fruits (21%), and carbohydrates (15%). Fruits were the most frequently used plant part for food (61%). The species with the highest use value was Cacica papaya (1.07). Additionally, the traditional food with the highest fidelity level was serbet (62.82%). These findings emphasize the importance of integrating a diverse range of plant resources into food systems to enhance food security and stimulate economic development in the region.

Abstract

The mangrove area is a nutrient-rich zone that serves as a food source for various aquatic organisms and as a spawning and nursery ground for species such as fish, crabs, and clams. The aim of this study is to investigate the morphometrics and growth pattern of blood cockle (Tegillarca granosa) in the mangrove area of Langsa City. Data collection for T. granosa was conducted using purposive sampling at three designated research locations with varying environmental conditions. Transects were established from the shoreline towards the mangrove vegetation at each research location. Within each transect, 1 meter x 1 meter plots were established for T. granosa sampling. The blood cockles found at the research sites were measured for shell length, shell width, and total weight. The research collected 98 individuals of T. granosa at the study location, with morphological variations including length, width, total weight, and sex. The size of the blood cockles ranged from 3 cm to 6.76 cm, the shell width ranged from T. granosa 2.50 cm to 5.52 cm, while the total weight of T. granosa ranged from 12 grams to 122 grams. Based on morphometric analysis, the growth pattern of T. granosa in the mangrove area of Langsa City is characterized by b = 2.5085, falling into the negative allometric category. This growth pattern indicates that the length of T. granosa grows faster compared to its total weight. Location 1 (Lhok Banie) showed the best growth pattern for T. granosa, the least favorable growth was found at Location 3 (Kuala Langsa). In conclusion, the morphometrics of T. granosa at the study site showed significant variation in length, width, and total weight. Morphometric analysis indicates that T. granosa exhibits a negative allometric growth pattern.

Abstract

This study in pharmaceutical packaging manufacturing focuses on improving compressed air efficiency through targeted strategies at both the source and user levels by establishing a baseline to analyze energy consumption patterns. Key measures, including minimizing air leaks, adjusting pressure, and optimizing compressor performance, aim to achieve a 20-50% increase in efficiency, thereby supporting environmental sustainability. The User Point and Source Point approaches are expected to lower Specific Power Consumption (SPC), with data collected from December 2020 to May 2022 providing insights into potential energy savings. Establishing this baseline, based on machine runtime and productivity, offers a solid foundation for evaluation. Results show a 23% reduction in compressor electricity usage and a 7-8% decrease in compressed air consumption. A structured improvement process and strong collaboration between engineering and management are essential for enhancing productivity and achieving sustainable energy efficiency in the industrial sector.
