Abstract

Penelitian tentang struktur komunitas mangrove asosiasi di sekitar area tambak telah dilakukan pada bulan Mei-Desember 2016 di Desa Balandatu Kecamatan Mappakasunggu Kabupaten Takalar Sulawesi Selatan. Penelitian ini bertujuan untuk mengetahui jenis, kerapatan, frekuensi, penutupan, INP, SDR (Standard Dominance Rasio), dan penyebaran mangrove asosiasi di daerah tersebut, serta membandingkan struktur komunitas mangrove asosiasi di daerah tambak dan non tambak. Pengambilan dilakukan dengan metode purposive sampling menggunakan transek sabuk di daerah tambak dan transek kuadrat di daerah non tambak. Data yang diperoleh dianalisis secara kuantitatif untuk mendapatkan nilai SDR (Standard Dominance Rasio). Data penyebaran spesies dihitung berdasarkan Indeks Morisita. Dari hasil pengambilan data diperoleh 36 spesies mangrove asosiasi dari 22 familia, terdiri dari 11 spesies (7 familia) di daerah tambak dan 26 spesies (19 familia) di daerah non tambak. Nilai SDR tertinggi dari 5 stasiun di daerah tambak terdapat di stasiun 1 ditemukan pada rumput Fimbristylis cymosa dengan nilai 100%, sedangkan di daerah non tambak nilai SDR tertinggi ditemukan di stasiun 3 pada semak Kirinyu Eupatorium odoratum dengan nilai 75,48 %.  Mangrove asosiasi umumnya memiliki pola penyebaran mengelompok. Dapat disimpulkan bahwa mangrove assosiasi di daerah non tambak dan tambak memiliki struktur komunitas berbeda dengan penyebaran mengelompok. Kata kunci: Struktur komunitas, mangrove asosiasi, Desa Balandatu, Tanakeke, Sulawesi Selatan

Abstract

This study aims to determine the effect of monosodium glutamate on LH and testosterone levels in serum of adult male rats (Rattus norvegicus). A total of 12 male Wistar-strained rats divided into three groups with 4 rats per group. Control group was given distilled water, while M1 was given MSG at a dose of 4mg g-1 BW for 15 days and M2 was given MSG at a dose of 4 mg g-1BW for 45 days. All substances were given orally. At the end of the study, rats were sacrificed with a dislocation to draw blood from the heart. Then, the blood was incubated at room temperature to obtain serum. Serum was used to analyze LH and testosterone levels using the ELISA kit. Data were analyzed using one way ANOVA (p ≤ 0.05) with SPPS 16.0 for windows. The results showed that serum LH levels after MSG treatments for 45 days was significantly decreased compared with the control. The serum testosterone levels M2 was significantly difference with the control group (p ≤ 0.01). This study predicts that monosodium glutamate have a direct and indirect effect on male reproductive organs. Keywords: Luteinizing hormone, Monosodium glutamate, testosterone.

Abstract

Background & Objective: Dandruff is a scalp condition attributed to the fungus Malassezia sp. It manifests as fine to coarse scales that are grayish or white, resulting from the shedding of the stratum corneum layer on the scalp. Factors contributing to the onset of dandruff include the proliferation of Malassezia fungi, sebaceous gland activity, and individual predisposition. This study aimed to identify Malassezia sp. responsible for dandruff among female students at the Muhammadiyah Polytechnic of Makassar. Method: The research employed a laboratory observational design utilizing a purposive sampling technique. Dandruff samples were collected from 10 female students and cultured on SDA (Sabouraud Dextrose Agar) media, followed by microscopic examination of the resulting colonies. Result: The findings revealed that none of the 10 dandruff samples contained Malassezia sp.; instead, contamination by Aspergillus fumigatus was observed. Conclusion: Therefore, it can be concluded that Malassezia sp. was not identified as a causative agent of dandruff in female students at the Muhammadiyah Polytechnic of Makassar
