Abstract

Acid mine drainage (AMD) formed from open pit mining can cause environmental impacts if discharged directly into the waters because it has a low pH and contains heavy metals. Attempts to neutralize the pH and absorb heavy metals in AMD can be carried out by means of phytoremediation using Eleocharis dulcis (Burm.f.) Trin. Ex Henschel. This study aims to determine the activity of PO, PPO, and CAT on the roots of E. dulcis in AMD phytoremediation and evaluate the success of AMD phytoremediation. Sampling using convenience sampling method. Measurement of metal content of Fe and Mn with atomic absorption spectrophotometer (AAS). Protein extraction using refrigerated centrifugation, measurement of total protein content with BSA, and activity of PO, PPO and CAT using a uv-vis spectrophotometer. Based on research that has been done, E. dulcis is able to increase the pH from 5.6 to 7.7 and reduce Fe levels from 7.88 mg/l to 0.25 mg/l, Mn 1.71 mg/l to 0.75 mg /l. The physiological response shown by E. dulcis in AMD phytoremediation was an increase in antioxidant enzyme activity PO 178.98 U/mg protein/minute, PPO 388.96 U/mg protein/minute and CAT 184.34 U/mg protein/minute. Based on research, E. dulcis is a plant that is tolerant to pH stress and heavy metals, so it has the potential to be used in AMD phytoremediation.

Abstract

Murraya koenigii (L.) Spreng is often known as Temurui or Curry as a local name in Indonesia, and has long been used in medicine and has as a potential as a multi-medicinal plant. Temurui as a producer of bioactivity has the antioxidant properties. This is due to the presence of metabolite compounds contained in the leaves of the Temurui plant. Leaves are organs that are always growing where chemical components such as chlorophyll in the leaves will also develop thereby affecting leaf metabolism in plants. This study aims to determine the contens of chlorophyll, contens of antioxidants and metabolite compounds in Temurui leaves at the level of leaf development. Different leaf extractions are also used to measure the antioxidant, chlorophyll content and metabolite compounds found in Temurui leaves. The research results obtained on young, and old Temurui leaves obtained a total of 3 groups of dominant compounds, terpenoids, organic acids and esters, and mature leaves not find ester compound. The level of leaf development affects the contents of antioxidants and chlorophyll contents. Chlorophyll content in mature leaves was 44.60ug/ml, young leaves were 41.28ug/ml and old leaves were 30.27ug/ml while antioxidant contents in young leaves were 8.949ppm, mature leaves were 8.85ppm and old leaves were 8.429ppm.

Abstract

Tanjung Senai Ogan Ilir Sumatera Selatan merupakan kawasan rawa lebak musiman yang unik, mempunyai banyak potensi seperti perikanan, peternakan, pertanian, perkebunan dan ekowisata. Potensi yang menarik untuk dikembangkan pada kawasan ini salah satunya yaitu potensi ekowisata dengan aspek flora, fauna dan landscape. Upaya untuk mempertahankan fungsi ekologis dan memanfaatkan potensi yang ada di rawa kawasan Tanjung Senai Ogan Ilir secara berkelanjutan maka aspek flora perlu dikaji lebih lanjut dengan penelitian, karena keanekaragaman flora belum banyak dieksplorasi pada kawasan rawa dengan karakteristik tergenang secara musiman. Tujuan penelitian ini untuk mengetahui komposisi, keragaman dan struktur jenis-jenis tumbuhan penyusun rawa lebak Tanjung Senai Ogan Ilir. Komposisi vegetasi rawa lebak Tanjung Senai Ogan Ilir disusun oleh 9 spesies tumbuhan yang terdiri dari 6 famili diantaranya famili Cyperaceae terdapat 3 spesies, Poaceae terdapat 2 spesies, Loganiceae, Myrtaceae, Phyllanthaceae, dan Rubiaceae masing-masing terdapat 1 spesies. Keragaman vegetasi rawa lebak Tanjung Senai Ogan Ilir termasuk kategori rendah dengan nilai indeks keanekaragaman (H’) 0.72. Struktur vegetasi rawa lebak Tanjung Senai dikuasai oleh tumbuhan tingkat tiang yaitu Melaleuca cajuputi Powell (dengan nilai penting 218,6%), tingkat pancang Hymenocardia punctata Wall. ex Lindl. (178,5%) dan tingkat semai Fimbristylis acuminata Valh. (150,1%). Dapat disimpulkan bahwa berdasarkan komposisi, keragaman dan struktur vegetasi rawa lebak Tanjung Senai maka dalam pengelolaan, pengembangan dan pemanfaatannya harus memperhatikan fungsi ekologis kawasan tersebut.

Abstract

The butterfly flowers (Clitoria ternatea L.) are used as natural dyes and herbal medicines because they contain metabolites, anthocyanins and antioxidants. The content of these metabolites is influenced by the phase of flower development. This study aims to determine the levels of anthocyanins, antioxidants and metabolites of butterfly pea flowers from different flowering phases. The Butterfly flower collection was taken from the village of Mulyaguna, Teluk Gelam, Ogan Komering Ilir, South Sumatra. The extraction was carried out with 70% ethanol solvent, and determination of the amount of anthocyanin content by spectrophotometry, antioxidant content by DPPH method, and metabolite compounds by GC-MS. Data on anthocyanin and antioxidant content were analyzed with averages and standard deviations, and GC-MS chromatograms were traced for compounds with reference to the PubChem, KEGG, ChEBI, PlantCyc, and Spectrabase websites, which then determined the dominant compound group. The results of the study on blooming butterfly pea flowers found that the antioxidant content was 6.58 ppm, higher than that of bud flowers, which were 2.55 ppm, and wither flowers, which were 1.74 ppm. The anthocyanin content of the blooming butterfly pea flower was 40.33 ppm, the withering flower was 4.36 ppm, and the bud flower was 3.60 ppm. The dominant metabolites were identified as fatty acids, organic acids, aromatics and flavanoids, followed by differences in antioxidant and anthocyanin content in the flowering phase of the butterfly pea flower

Abstract

Knowledge about medicinal plants in the Besemah tribe community in Jarai District and Sukamerindu District, Lahat Regency, South Sumatra Province, has long been known and used for generations and stored as local wisdom of the community. The use of medicinal plants as one of the community's solutions to cure infectious diseases, with natural medicinal materials the side effects caused are relatively less. This study aims to inventory and identify the types of medicinal plants and types of medicinal plants typical of the Besemah tribe, how to process, how to use, and how to use specifically to treat infectious diseases in the Besemah tribe in Jarai District and Sukamerindu District, Lahat Regency, South Sumatra Province. This research will be conducted from January to March 2023. The study was conducted using quantitative descriptive methods by conducting interviews with 9 traditional medicine (battra) as sources of information. The results showed that plants used as medicine by the Besemah tribe community as many as 94 species of plants from 47 families to treat 29 infectious diseases. There are seven species of typical plants of the Besemah tribe, namely Tetap kadam (Hadgsonia macrocarpa (Blume) Cogn.), Tetungau (Debregeasia longifolia (Burm.f) Wedd), Memban burung (Donax canniformis (G.Forst) K.Schum), Temperingat (Rubus moluccanus L.), Tapal selembar (Monophyllaea horsfieldii R.Brown), Sedingin hutan (Fissistigma fulgens (Hook.f & Thomson) Merr.), Memaye (Leea indica (Burm.f.) Merr), and the typical way of processing is that the stem is cut, the water is collected and drunk directly. The most widely used plant part is the 38% leaf part. The most processing method is used by boiling 46% and the most use method by drinking 53%.
