Abstract

Pohon riparian merupakan salah satu komponen penyusun ekosistem riparian (seperti mata air). Riparian terrmasuk sebagai daerah konservasi khusus yang perlu dipertahankan vegetasi aslinya karena jika vegetasi riparian semakin menyusut yang berdampak pada penurunan keanekaragaman hayati dan hilangnya fungsi vegetasi riparian tersebut Tujuan penelitian ini adalah untuk mengetahui jenis-jenis pohon ripaian yang terdapat di sumber mata air desa merbaun, kecamatan Amarasi barat, kabupaten Kupang, Nusa tenggara Timur. Penggumpulan data terdiri dari tingkat kealamian dan  keanekaragaman spesies. Pengumpulan data jenis tingkat kealamian terhadap pohon riparian  mengunakan indeks naturaliness dan indeks hemeroby). penarikan sampel pohon menggunakan metode kuadrat (Quadrat Sampling Technique) yang dilakukan secara acak. Di setiap plot, dilakukan identifikasi tumbuhan. Pengenalan nama tumbuhan menggunakan nama lokal, yang dirujuk ke nama ilmiah atau nama binomial. Analisis data terdiri dari status endemisme, indeks kekayaan jenis (Dmg), indeks keanekaragaman Shanon- Wiener (H’), dan indeks dominansi (D). Hasil penelitian ditemukan 15 jenis pohon yang terdiri dari 11 jenis endemik dan 4 jenis eksotik. Dmg dan H’ tergolong sedang, dengan tidak ada jenis pohon yang mendominasi.

Abstract

Gastropods act as environmental bioindicators because they are sensitive to changes in the aquatic environment. The purpose of this study was to determine the diversity of gastropod species on Muko Wujo Beach. Determination of sampling points using the purposive sampling method. Samples were taken at two different stations based on human activities. The stages in collecting data on gastropod species include observing gastropods found in a 1x1 m plot, counting the number, and then recording it for identification purposes. In addition, environmental parameters, namely temperature and pH, were measured. Data on gastropod species and environmental parameters were then analysed qualitatively and quantitatively. Qualitative analysis was carried out by describing the morphological characteristics of gastropods, and identification was carried out using the help of scientific articles and internet websites. Quantitative analysis was carried out by calculating the diversity index, dominance index and similarity index of gastropod species. The results showed that 29 types of gastropods were found on Muko Beach, Larantuka District, East Flores Regency, which were divided into 14 families and 7 Orders. The diversity index, dominance index, and similarity index of gastropod species on Muko Wujo Beach were classified as moderate.

Abstract

Springs are groundwater that comes out on its own to the surface of the earth. Water sources originating from springs are generally suitable for direct consumption because they undergo natural purification. However, the high demand for clean water causes springs to experience anthropogenic pressure, which can reduce the quality of spring water. The study aimed to determine the Bacteriological quality of spring water in Toobaun village. The method used in this study was the Most Probable Number (MPN), using a series of five tubes with a variety of 5-5-5. The test included three stages, namely the prediction test, the confirmation test, and the complete test. The data obtained were presented in the form of a table, then compared with the MPN table value and analyzed descriptively by comparing the MPN value with the water quality standard, namely PP No. 22 of 2021 (class I). The results of the study showed that the Fecal Coliform value found was 220 MPN/100ml and did not meet the quality standards of PP No. 22 of 2021 (Class I). In the complete test using EMBA media, three types of bacteria were found that had characteristics similar to Escherichia coli and Salmonella sp. Klebsiella sp. Based on the results of water testing at the Toobaun spring, it cannot be consumed directly without first being processed.
