Abstract

Introduction: Management of low vision in pediatric patients with greater result  can affect their quality of life than in adult low vision patients.. Retinopathy of Prematurity is the main cause of blindness in children. A case study highlights the tertiary prevention (low vision examination and management) in a 5 year old boy with ROP related blindness to optimize his remaining visual capacity by using optical and  non optical aids that support daily activity and educational learning.Case Report: A 5 year old boy with ROP related blindness visited to the low vision clinic after receiving the several treatments for ROP before. His visual acuities were light perception in the right eye and hand movement in the left eye using his current spectacle correction. He had anti VEGF bevacizumab intravitreal injection, vitrectomy and complicated cataract extraction history on the left eye. He wasdifficult to learn and read numbers and alphabets caused by visual impairment.Discussion : Upon evaluation by assessment low vision method, his distance visual acuity in the left eye was improved significantly up to 3/40 on LEA Acuity chart with +14.00D. His near vision became 10 M at 30 cm of reading distance (without near correction) and 4 M at 13 cm  improved with +3.00 D by spectacle. The non optical aid devices as reading task were also suggested to improove continuous  reading text without difficulty.Conclusion: ROP blindness can be preventable if appropriate, adequate and accessible screening programmes are available. Unfortunately, even with the current screening guidelines and recommended treatment of ROP, many babies suffer from blindness by this disease each year. Low vision assessment and management in pediatric patient with visual impairmentaccording to children's need can optimize the recent visual capability of low vision patient and give self care daily activity and educational learning.

Abstract

Background: Leachate is water formed from piles of rubbish containing inorganic and organic compounds. One example of an organic compound that can cause environmental pollution is Pb (lead). Efforts to reduce levels of the heavy metal Pb are by carrying out phytoremediation using aquatic bamboo plants (Equisetum hymale). Methods: This research was conducted during September 2024 at the Green House, Medan State University, with leachate water samples taken from the Dendang Sea Final Waste Disposal Site (TPAS), Medan Tembung District, Deli Serdang Regency, North Sumatra Province. Methods used in the research This method uses descriptive or observational methods which are presented in the form of tables and graphs. Results: Research shows that water bamboo plants are able to absorb Pb levels in leachate water as seen from the parameters of changes in pH, temperature, color and physical condition of water bamboo plants. Conclusion: Water bamboo can be used as phytoremediation to reduce Pb levels in leachate waste.

Abstract

Pencemaran air limbah domestik oleh bakteri coliform menjadi salah satu permasalahan utama yang berdampak terhadap lingkungan dan kesehatan masyarakat. Penelitian ini bertujuan untuk menganalisis keberadaan dan tingkat kontaminasi bakteri coliform dalam air limbah domestik menggunakan metode Most Probable Number (MPN). Pengujian dilakukan terhadap lima sampel air limbah domestik melalui dua tahap utama, yaitu uji perkiraan menggunakan Lauryl Tryptose Broth (LTB) dan uji penegasan dengan Brilliant Green Lactose Bile Broth (BGLB). Hasil penelitian menunjukkan bahwa seluruh sampel yang diuji positif mengandung bakteri coliform, dengan nilai MPN berkisar antara 1.700 hingga 16.000 MPN/100 mL. Empat dari lima sampel memiliki kadar coliform yang melebihi batas maksimum yang ditetapkan oleh PERMENLHK No. P.68 Tahun 2016, yaitu >3000 koloni/100 mL, yang mengindikasikan potensi pencemaran biologis yang serius. Faktor-faktor lingkungan seperti suhu, pH, kandungan bahan organik, dan salinitas berkontribusi terhadap variasi tingkat pencemaran coliform dalam air limbah domestik. Hasil penelitian ini menegaskan bahwa pengolahan limbah domestik yang tidak memadai dapat meningkatkan risiko pencemaran lingkungan serta membahayakan kesehatan masyarakat. Oleh karena itu, diperlukan sistem pengolahan limbah yang lebih efektif serta pemantauan berkala terhadap kualitas air limbah sebelum dibuang ke lingkungan.
