Abstract

Pteris vittata has a high morphological variation and it has wide geographic regions around the world . Study of morphology and its correlation with with altitude of plant origin area in Java is very little informed. This aims of this research were first to study the diversity of morphological characters of P. vittata from Java; and to know the correlations among morphological characters to the plant orignated altitute; This study was conducted from September 2012 until September 2013. Plants materials were  collected by exploration method.  Morphological observations carried out on 130 individuals that had been collected from West Java, Central of Java and Yogyakarta in various altitude areas. Pteris vittata from Java Island varied in the morphological characters. The varied in the morphological characters i.e. size and shape of fronds, pinnae and apical segment. Variations in morphology was not correlated with altitude of plant origin area. Taxonomycally, P. vittata in Java can be divided into two groups infraspecies, namely P.vittata subspecies vittata and P.vittata subspecies emodi.

The purpose of this study was to determine the prevalence of hypercholesterolemia in adoles­cent patients in the Thamrin clinical laboratory in Medan 2017. This study was conducted in June 2018 with descriptive methods obtained by collecting secondary nomina from the results of the patient's laboratory examination. Based on the results of the study of the prevalence of hypercholesterolemia that occurred in adolescents as many as 123 people with a percentage of 17.7% of the number of adolescent patients who visited.

Abstract

Penelitian tentang Preferensi Pohon Bagi Burung di Kawasan Restorasi Resort Sei Betung Taman Nasional Gunung Leuser Sumatera Utara telah dilakukan pada bulan Januari - Maret 2017.  Penelitian ini bertujuan untuk mengetahui jenis pohon restorasi yang paling sering dikunjungi oleh burung, aktivitas dominan yang dilakukan oleh burung pada pohon, dan faktor yang mempengaruhi kehadiran burung pada pohon di kawasan restorasi Resort Sei Betung. Metode yang digunakan dalam penelitian ini adalah survei eksploratif, dengan menggunakan binokuler, kamera digital, dan buku panduan identifikasi burung. Pengamatan jenis dan aktivitas burung dilakukan pagi dan sore hari. Hasil penelitian menunjukkan bahwa terdapat 5 jenis jenis pohon restorasi yang paling sering dikunjungi oleh burung yaitu Vitex pubescens, Phyllanthus sp, Calicarpa pentandra, Callerya artropurpurea, dan Macaranga indica. Pohon Vitex pubescens merupakan pohon dengan kunjungan burung paling banyak yaitu 73 kali kunjungan. Phyllanthus sp adalah jenis pohon dengan kujungan burung paling banyak kedua yaitu sebanyak 51 kunjungan. Pohon Macaranga indica, pohon Calicarpa pentandra, dan pohon Callerya atropurpurea, masing-masing sebanyak 30, 28, dan 26 kunjungan burung. Aktivitas dominan yang dilakukan oleh burung pada pohon adalah aktivitas singgah. Faktor yang mempengaruhi tingkat kehadiran burung pada pohon adalah ketersediaan pakan, kondisi tajuk, tinggi tajuk, ukuran cabang dan kelebatan daun.
