Abstract The Communities in Huilelot and Uiasa Village have the knowledge of traditional medicine by using various types of plants that have medicinal ingridient around them starting from the yard of the house, garden, roadside to the forest. From the Information obtained, this study was aim to determine the types of plants that have medicinal ingridient, medicinal parts/organs of medicinal properties, methods of treatment, diseases that are cured by using medicinal plants by the community and the cultivation of medicinal plants in Huilelot and Uiasa village. This research was conducted in October - November 2017. The method used in this study was roaming, while sampling and data collection of medicinal plants was carried out by exploration methods around the site. The Work procedures include preparation consisting of observation, determination of informants, and preparing tools and research materials. The implementation phase consists of interviews, exploration and documentation and identification. The data analysis technique used was descriptive analysis, which was presented in the form of a table then matches plants with images or examples according to the source of the literature. Based on the results of the study, 31 types of plants with medicinal properties were used by the community. Plant organs used were leaves, stems, fruits, seeds, tubers, roots and all organs. The most widely used part is leaves. The method of concocting is boiling, pounding, chewing, eating directly, trimming, blending and boiling. Most of mixing  methode used was boiled. Diseases that can be cured include high blood pressure, blood sugar, intestines, scabies, liver, abdominal pain, hernias, stomach, vaginal discharge, goiter, malaria and heat, uterine tumors, cancer and breast tumors, pain during childbirth, rheumatism, kidney, urine stones, diabetes, myopic eyes, cuts, bleeding, and broken bones or accidents. From the results of the study there were 12 species cultivated at home and in the garden, while 19 other species grew wild (sabana) or not cultivated by the community

Sea star is an invertebrate animal that is included in the phylum Echinoderms from the Asteroidea class. Radial symmetry is shaped and generally has five or more arms and does not have a frame that helps movement. This study aims to determine the diversity of sea star (Asteroidea) in Lamalaka Beach, Ile Boleng District, East Flores Regency.This research will be conducted in July-August 2019, the location of the study is on the Lamalaka coast, Ile Boleng District, East Flores Regency.The method used is a survey method, based on the presence of Asteroidea species that are considered to represent the area. The steps in data collection are field survey, observation, identifying species in each plot, observing and recording their marphological characteristics.Sampling uses the technique of determining the location of sampling using Area sampling. To identify based on Human and Deloach identification guidelines, 2010. Analysis of the data used in this research is quantitative descriptive and the composition of Asteroidea species can be stated based on visual observations calculating species density, relative density, and dominance index, diversity.Based on the results of the study, found 4 species of Asteroidea, namely Protoreaster nodulosus, Linckia laevigata, Echinaster luzonicus, Astropecten polyacanthus. The highest species density calculation results were found in P. nodulosus species with a value of 0.78 ind / m2. while the lowest species density was found in L.laevigata species with a value of 0.63 ind / m2. The highest relative density was found in P. nodulosus species with a value of 27.64%, and the lowest relative density found in L.laevigata species with a value of 22.35 %. The index of starfish species dominance in Lamalaka Beach, obtained a value of D <0.5, indicates that there are no species that dominate in Lamalaka Beach. The existence of starfish in Lamalaka Beach, Ile Boleng District, East Flores Regency needs to be preserved. One form of effort to preserve it is to conduct monitoring with routine monitoring to monitor the condition of the sea star population in these waters. Besides that, it is also necessary to increase the utilization of sea stars as one of the natural tourism objects and as an Ecoedutourism tourism object. Thus, the presence of starfish will be felt by the wider community so that awareness to maintain the existence of starfish will be increased.

Penelitian ini bertujuan untuk menguji kualitas air pada sumber Mata Air Waipidi, Desa Wairasa Kecamatan, Umbu Ratu Nggay Barat, Kabupaten Sumba Tengah dengan uji 3 parameter yaitu fisik, kimia, dan biologi. Metode yang digunakan dalam penelitian ini adalah deskriptif kuantitatif dengan membandingkan data hasil pengukuran dari masing-masing parameter air dengan nilai baku mutu PP No. 82 Tahun 2001. Berdasarkan hasil penelitian pada Mata Air Waipidi, hasil analisis uji kualitas air ditemukan parameter yang memenuhi standar baku mutu  yaitu: parameter fisik meliputi: Suhu (23⁰C), TDS (187 mg/L), TSS (O,OO24 mg/L); parameter kimia meliputi: pH (7,52 mg/L), BOD (0,32 mg/L), nitrat (5,5 mg/L), nitrit (0,049 mg/L), sulfat (7 mg/L), dan parameter biologi meliputi: uji total coliform (<1,8 ml). Parameter yang tidak memenuhi standar baku mutu yaitu: parameter kimia yang meliputi: DO (4,77 mg/L), besi (0,77 mg/L), mangan (0,117 mg/L), fosfat (0,54 mg/L), klorin (0,24 mg/L), sianida (0,14 mg/L), dan tembaga (0,45 mg/L). Faktor-faktor yang menyebabkan beberapa indikator tidak memenuhi standar baku mutu air disebabkan oleh limbah dari irigasi pertanian, pembusukan daun, dan aktivitas alam seperti erosi, dan pelapukan bebatuan. Mata air Waipidi dikategorikan tidak memenuhi standar baku mutu air kelas 1 berdasarkan PP No. 82 tahun 2001 yang dapat digunakan sebagai air minum namun mata air Waipidi disarankan untuk digunakan sebagai prasarana/sarana rekreasi air, pembudidayaan ikan air tawar, peternakan, dan mengairi budidaya tanaman.
