Mangrove forests have an important role in regulating the stability of sea and land conditions, as well as forming various species of trees, shrubs and flora. One area that has a mangrove ecosystem in Bengkalis Regency is Teluk Pambang Village. Mangrove ecotourism in Teluk Pambang has good potential to be developed such as natural resources, characteristics and uniqueness of mangroves, diversity of mangrove species and regional comfort. The aims of this research are (1) know the potential and attractiveness of mangrove ecotourism and (2) determine the strategy of developing mangrove ecotourism in Teluk Pambang Village, Bantan Regency, Bengkalis Regency. This research began in December 2018 in the village of Teluk Pambang, Bantan Regency, Bengkalis Regency. The study was conducted using methods of field observation, observation and study of literature. Analysis of the ecotourism development strategy was carried out in the SWOT analysis. The potential of mangrove forest ecotourism in Teluk Pambang has beautiful natural scenery, a high level of security, and there are 10 species of fauna and 9 species of flora. Based on differences in the number of internal and external factors, the Strategy Matrix is in quadrant 1. Strategies to develop mangrove forest ecotourism, namely increasing human resources (HR), planting rare mangrove species, planting mangrove abrasion barriers, development, procurement of facilities and supporting infrastructure so both among the stakeholders.
This study aims to determine the potential of plants as biopesticides found around Riau University campus. The method used consists of vegetation analysis and renaissance methods. The vegetation analysis method was used in the arboretum area of the Riau University while the renaissance survey was carried out on agricultural gardens, shrubs, and road shade plants. From the survey results, there were 25 types of botanical pesticides with the highest growth rate at the seedling and understorey plants.
Lahan gambut di Provinsi Riau dapat dimanfaatkan dan dikelola di bidang pertanian dengan menerapkan sistem agroforestri, Salah satunya di Desa Dayun yang terletak di Kecamatan Dayun, Kabupaten Siak, Desa Lalang yang terletak di Kecamatan Sungai Apit, Kabupaten Siak, dan Desa Lalang Tanjung yang terletak di Kecamatan Tebing Tinggi Barat, Kabupaten Kepulauan Meranti. Faktor yang mendukung untuk menerapkan sistem agroforestri ialah sistem agroforestri berupa jenis produk yang dihasilkan yang sangat beragam dibanding, namun pengembangan agroforestri dipengaruhi oleh tanggapan masyarakat atau persepsi. Penelitian ini bertujuan untuk mengkaji persepsi masyarakat terhadap agroforestri pada lahan gambut di Provinsi Riau. Penelitian ini menggunakan metode snowball sampling dan pengumpulan data diperoleh melalui wawancara mendalam, observasi, dan studi dokumen. Data yang diperoleh dari hasil penelitian dianalisis dengan analisis deskriptif kualitatif. Hasil penelitian menunjukkan bahwa persepsi masyarakat terhadap agroforestri pada lahan gambut di Provinsi Riau dapat dilihat dari pola penanaman dan pemilihan jenis tanaman agroforestri yang sesuai pada lahan gambut. Masyarakat juga beranggapan bahwa agroforestri pada lahan gambut sudah memberikan kontribusi baik dari aspek sosial ekonomi maupun ekologi. Adanya beberapa tanggapan/persepsi mengenai pertimbangan dan persiapan dalam menerapkan agroforestri pada lahan gambut. Masyarakat juga memberikan tanggapan yang baik terhadap keberlanjutan agroforestri dan berharap agroforestri dapat diterapkan seterusnya.
Kepuh is multipurpose plant which began endangered. Information on ethnobotanical studies or knowledge and use of this species is still limited. This research is structured to answer this problem. By using the method of interviewing community leaders in Sumbawa, this study found that local wisdom related to kepuh is quite diverse. Good knowledge as well as the use of kepuh found among others for food, medicine, bio-fuel, jewelry, building materials, traditional ceremonies, handicrafts, traditional games, and environmental services. Information on the benefits of kepuh should be disseminated. It is hoped that the ethnobotanical study of kepuh can be a good start to support kepuh conservation in the future.
High-resolution satellite imageries believed to map the mangrove area well. Two satellite imageries with almost similar spatial resolution were expected to achieve this objective, including SPOT (Satellite Pour l’Observation de la Terre) 6 and a RapidEye. Two images covered the same area and acquired under the equivalent season at Kembung River, Bengkalis Island, Riau Province. A comparison was tested on several objectives. First, a comparison was conducted band by band through examining their statistical spectral analysis. RapidEye had a higher variance in all visible bands but low at NIR. Second, spectral separability using Jeffrey-Matusita distance was executed with three-band composites (SPOT 6/VNIR; RAPIDEYE/VNIR and RAPIDEYE/VNIR+RedEdge). SPOT 6 had better separability than RapidEye imageries compositions (VNIR+RedEdge and VNIR), with an overall accuracy of 79.9%, 75.3%, and 67.3%, respectively. Third, mangrove land cover classification. Three pixel-based classification rules were used, including a general classifier, maximum likelihood (ML), and two advanced classifiers, i.e., neural network (NN) and support vector machine (SVM). Results indicated that the use of SPOT 6 produced better overall accuracy than the other two image composition for each classifier. SVM was promising in the mangrove mapping algorithm compare to NN and ML.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
