Abstract

Status gizi adalah keadaan seseorang atau sekelompok orang yang ditentukan oleh konsumsi, penyerapan dan pemanfaatan nutrisi makanan. Pola hidup mempengaruhi status gizi seseorang siswa terutama yang berasal dari luar kota sering kali disertai asupan makanan yang dikonsumsinya, sehingga kebiasaan tersebut akan mempengaruhi status gizinya. Tujuan dari penelitian ini yaitu, untuk mengetahui status gizi seseorang sehingga dapat menjadi data awal untuk dievaluasi kembali. Penelitian ini menggunakan metode gabungan perpaduan antara deskriptif dan kuantitatif, yaitu dengan cara menyebarkan quisioner, dengan itu akan terlihat gambaran status gizi seseorang berdasarkan hasil Quisioner dan perhitungan. Untuk mengetahui status gizi tersebut dapat dilakukan dengan perhitungan Body Mass Index atau Indeks Massa Tubuh yang dilakukan dengan menggunakan berat badan dalam satuan kilogram, tinggi badan dalam satuan centimeter (kg/cm), lingkar perut (cm), lingkar lengan (cm) untuk menghitungnya . Dari data yang diperoleh sekitr 53% mahasisa memiliki berat badan normal atau ideal, 27% dengan berat badan kurang, 17% memiliki kelebihan berat badan dan sekitar 3% digolongkan obesitas.

Abstract

Betta fish (Betta sp.) are freshwater fish that are widely kept as ornamental fish and are known to have quite good adaptability to the environment. However, water quality and type remain important factors that influence the survival and growth of Betta fish. This study aims to determine the effect of water type on the survival of Betta fish (Betta sp.). The study was conducted experimentally for five days in the Biology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Padang State University. Three Betta fish were used as research objects, each kept in different water media, namely regular water (tap water), nano water, and AC water. The parameters observed included fish survival, behavioral changes, physical condition, and water quality including temperature, pH, and dissolved oxygen levels. The results showed that Betta fish kept in nano water showed the most optimal conditions, characterized by better growth in body weight and length and a high survival rate. Betta fish in regular water also showed good survival, although they required water management to reduce chlorine content. Meanwhile, Betta fish kept in AC water showed lower survival and growth rates, as well as signs of stress due to an imbalance in mineral content. Therefore, it can be concluded that water type influences Betta fish survival, and nano water was the most effective maintenance medium in this study.

Abstract

Studies on diversity and vegetation structure have been widely conducted in plant ecology, yet research that specifically examines variation in plant community structure based on different quadrat sizes at a single observation site remains relatively limited. This study aimed to analyse the composition, structure, and dominance of plant vegetation using the quadrat method at several observation scales. A descriptive quantitative approach with a field survey design was employed by placing 2 × 2 m and 5 × 5 m quadrat plots along transect lines determined systematically with a random starting point. Data were collected through direct observation and recording of the number of individuals, frequency of occurrence, density, dominance, and the Importance Value Index (INP) of each plant species, and then analysed quantitatively to characterise the structure of the vegetation community at each growth level. The results showed differences in species composition and dominance patterns for each quadrat size, with strong dominance by several particular species both in the understorey strata and at the sapling and shrub levels. These findings enrich understanding of the relationship between observation scale and vegetation community structure and underscore the importance of using varied quadrat sizes in vegetation analysis. This study also provides practical implications as baseline ecological data to support the management and monitoring of plant diversity at the local level, as well as opening opportunities for further research with broader spatial and temporal coverage.
