Mangrove merupakan ekosistem yang khas dan memiliki fungsi penting secara ekologi, sosial-ekonomi, dan pendidikan. Luas kawasan mangrove di Kabupaten Purworejo semakin berkurang akibat adanya penebangan, permukiman, tambak,dan pertanian. Berkurangnya tegakan mangrove akan mempengaruhi keberadaan berbagai fauna yang berasosiasi dengannya. Oleh karena itu dilakukan pada bulan Agustus-September 2016 untuk mengetahui keanekaragaman kepiting biola di kawasan mangrove Kabupaten Purworejo, Jawa Tengah. Ada tiga stasiun, yaitu mangrove lebat (Desa Gedangan), mangrove sedang (Desa Jatikontal), dan mangrove jarang (Desa Ngentak). Dari penelitian didapatkan 7 jenis kepiting biola, yaitu Uca annulipes, U.crassipes, U.paradussumieri, U.rosea, U.tetragonon, U.vocans, dan U.vomeris. Indeks keanekaragaman kepiting biola di kawasan mangrove Kabupaten Purworejo, Jawa Tengah pada stasiun 1 (1,67)dan stasiun 2 (1,90) tergolong sedang. Adapun indeks keanekaragaman kepiting biola di stasiun 3 (0,64) tergolong rendah. Kondisi lingkungan di seluruh stasiun relatif baik untuk kehidupan mangrove dan kepiting biola, yaitu suhu26-30°C, pH 6-8, oksigen terlarut 3,5-6,6 mg/L, salinitas 3-9 ppt, dan substrat lumpur berpasir. Vegetasi mangrove pada stasiun I adalah Rhizophora mucronata, Nypa fruticans, Sonneratia alba, dan Hibiscus tiliaceus. Vegetasi mangrovepada stasiun II adalah Sonneratia caseolaris, Rhizophora stylosa, N.fruticans, H.tiliaceus, dan Morinda citrifolia.Vegetasi mangrove pada stasiun III adalah S.alba, S.caseolaris, N.fruticans, dan R.mucronata. Kerapatan vegetasi mangroveberkaitan dengan kelimpahan jenis (kepadatan) kepiting biola.

Indonesia is one of the largest mega biodiversity countries in the world that is rich in biological resources. Plants can be an alternative in treating diseases by Indonesian people such as around the Sesaot Forest, the Buwun Sejati Village. This study aimed to determine the types of plants in Sesaot Forest which were used as medicine by the people of Buwun Sejati Village, Narmada District, West Lombok Regency. This research was conducted by interview method and field survey. Data analysis was carried out descriptively. Based on the research, there were 87 species included in 42 families used as medicine by the community of Buwun Sejati Village. The Zingiberaceae family was a plant family that was most widely used as a traditional medicine ingredient. There were 30 types of diseases treated using Sesaot Forest plants by the community of Buwun Sejati Village. Leaves were of the most common part of plant used as raw material for traditional medicine by the people of Buwun Sejati Village, Narmada District, West Lombok Regency. The advantages of traditional medicines include its widespread accessibility and relative low prices. Therefore, this data obtained from this study is necessary to inventory the kind of medicinal plants and their utilization by the community, so that, the traditional knowledge of the medicinal plants can be documented and preserved.

Mangrove areas have important roles of ecologic, socio-economic, and socio-culture in ecosystem. Mangrove areas in Purworejo go into degradation as an impact of illegal logging, fishpond area expansion, settlements expansion and extension of agriculture area. All of the activities will influence the communities’ structure of mangroves vegetation and aquatic fauna. The purposes of research are to observe (i) biodiversity of mangroves aquatic fauna; (ii) correlation between mangrove vegetation and aquatic fauna; and (iii) the influence of abiotic factors towards biotic condition in research sites. This research was conducted in June-September 2016 at 3 stations and was determined with purposive sampling method. The research stations are Gedangan (Station 1), Jatikontal (Station 2) and Ngentak (Station 3). Vegetation of mangrove and aquatic fauna were observed with method of line transect and sampling removal. Association between variables (vegetation and aquatic fauna) is analyzed with Pearson Correlation Test. Influence of abiotic factors (physics and chemicals) on biotic (vegetation and aquatic fauna) is analyzed with t-test and regression test. According to the research, 34 species of aquatic fauna are from mangroves area of Purworejo. Highest value of aquatic fauna is found in Station 3 (ID 2.50). Pearson correlation test between vegetation and aquatic fauna obtains r value of 0,104. The t-test results a significant difference (sig 0.000) between abiotic factors and biotic condition and shows the impact of changes on both. Further test with regression method also indicates a weak impact on changes on abiotic factors towards biotic condition (r2 0.032).

Coastal ecosystems have high plant levels, for example mangroves and seagrasses. Mangrove forest is a type of forest located in tidal areas, especially on protected beaches, lagoons, river estuaries that are inundated and free from inundation at low tide, whose plant communities tolerate salt. Gedangan Village is one of the villages in Purwodadi District, which has mangrove areas in Purworejo Regency. This study aims to determine the types of mangrove plants that are useful the Gedangan Village, Purwodadi District, Purworejo Regency, Central Java as medicinal products. The study was conducted using roaming method in the form of observations or field observations in the mangrove area of Gedangan Village, Purwodadi District, Purworejo Regency, Central Java. Based on the research, there were eight (8) types of mangrove plants that were found as medicinal plants in Gedangan Village, namely Rhizophora mucronata, Sonneratia alba, Calotropis gigantea, Nypa fruticans, Acanthus ilicifolius, Hibiscus tiliaceus, Ipomoea pescaprae, and Wedelia biflora. Traditionally, these mangrove species can be used as a medicine items for beri-beri, hepatitis, ulcers, wounds, diarrhea, fever, antibacterial, anti-inflammatory, dizziness, asthma, bronchitis, dyspepsia, leprosy, tumors, diabetes, stomach ache, toothache, thrush, tuberculosis, muscle aches, and eczema.
