Abstract

Batam City is an industrial city and has a total area of 1,570.35 km2 with a land area of 715 km2. Following the economic development and increasing population, the green open space in Batam City is decreasing. The purpose of this research was to analyze the adequacy of Batam’s green open space based on the criteria of Law No. 26 of 2007 concerning Spatial Planning and Minister of Public Works Regulation No. 5 of 2008 concerning Guidelines and Utilization of Green Open Space. This research was conducted with a spatial analysis method based on land cover information from the interpretation of Landsat 8 OLI image recording on 05-06-2018. Based on the results showed that Batam’s green open space is still 221.400 ha or 32.05% from land area. It means, Batam City’s open space is still sufficient at least 30% according to Law No. 26 of 2007 and Minister of Public Works Regulation No. 5 of 2008. The largest type of land cover in green open space is secondary dry land forest, covering 79.200 ha (11.45%). Keyword : Batam City, analysis, green open space.

Abstract

Sumber daya alam yang sangat dibutuhkan manusia adalah air. Ketersediaan air tawar atau air bersih mengalami kelangkaan seiring dengan pertumbuhan penduduk. Salah satu sumber air tawar yang menjadi perhatian adalah sungai. Penelitian ini bertujuan untuk mengetahui kondisi tutupan lahan, aktivitas masyarakat serta menganalisis kaitannya dengan kualitas perairan Sungai Subayang tahun 2017-2020. Penelitian ini dilaksanakan di wilayah Sub-sub Daerah Aliran Sungai (DAS) Subayang, Kecamatan Kampar Kiri Hulu, Kabupaten Kampar pada Juni-Agustus 2021. Data primer penelitian didapatkan melalui observasi lapangan dan wawancara. Data sekunder meliputi data tutupan lahan bersumber dari KLHK dan data pengkuran kualitas air Sungai Subayang 2017-2020 bersumber dari Tim Fresh Water and Fisheries WWF Indonesia- Central Sumatra. Sampel pengamatan dari bagian hulu ke hilir berada di desa Aur Kuning, Batu Songgan dan Tanjung Belit. Penentuan status mutu kualitas air sungai dianalisis menggunakan pendekatan Indeks Pencemaran (IP) berdasarkan Peraturan Menteri Lingkungan Hidup Nomor 115 tahun 2003, dan penentuan baku mutu berdasarkan Peraturan Pemerintah Nomor 22 Tahun 2021. Hasil penelitian menunjukkan bahwa berdasarkan parameter suhu, kecepatan aliran sungai (arus), kekeruhan, oksigen terlarut, dan pH dari tahun 2017-2020, air Sungai Subayang berada pada kualitas baik dengan Indeks Pencemaran (IP) berkisar 0,27-0,80 (memenuhi nilai baku mutu kelas 2). Kualitas perairan yang baik tersebut berkaitan dan dipengaruhi oleh kondisi tutupan lahan yang masih didominasi hutan (97-99,15%), praktek pemanfaatan hutan dan sungai berbasis kearifan lokal, serta mulai membaiknya pengelolaan limbah dan aktivitas MCK oleh masyarakat.

Abstract

Friendly peatland utilization is often regarded as ‘difficult’, ‘adding new cost,” and ‘unfavorable’ to the cultivated crops. Such views appear to restrain farmers in general to adopt friendlier methods in utilizing peatlands. In response to the call for improving their practices farmers often demand proven peat-friendly but profittable practices. Therefore, convincing evidences, such as successful farmers with such practices as models, are needed. In one of villages in Siak regency, Riau Province, we encountered a farmer figure that is potentially promoted as a model in this regard. However, after evaluating what he really practiced, we found that some improvements were needed to make his practices truly peat friendlier. Our paper concerns the results of our interactions with this figure in order to improve the: (a) control of groundwater level; (b) prevention of peat decomposition; (c) prevention of peat subsidence; (d) reduction of carbon emission; (e) diversification of the farm’s products; (f) aesthetic value of the farm; and (g) promotion to potential visitors and market the farm’s products.

Abstract

Community engagement is often abruptly terminated as a project has to be officially ended following the termination of the fiscal year, which often leads to direct contact break off between project executors and their local counterparts. Consequently, a project initiated in the previous year may not persist in the following years. One strategy to cope with this problem is to use long-distance communication via handphone (HP) to continue the engagement of local counterparts. Our paper shares our experience as counterpart of Badan Restorasi Gambut (BRG) in engaging local communities carrying out peatland revegation in Bengkalis, Siak, and Kepulauan Meranti Regency of Riau. Revegetation was implemented as production and planting of natural forest tree seedlings. This paper evaluates the effectiveness of using long-distance communication for continuing our engagement in peatland revegetation. In our communications, technical and non-technical constraints of revegetation as well as the perceptions and expectations of our counterparts were discussed. We concluded, long-distance communication helps maintain “bonding” between project executors and their local counterparts, so that they do not feel left alone after a project has been formally terminated. Nevertheless, long-distance communication that is not accompanied with a real financial support to cover costs, eventually will not be sufficient.

Abstract

KHDTK Hutan Diklat Bukit Suligi is located in Dayo Village, Tandun District, Rokan Hulu Regency. Based on decree number 729/Menhut-II/2009 the area of ​​the Bulit Suligi Education and Training Forest KHDTK is 2,183 ha, but because of spirit of reform and regional autonomy in 1998, the community began to carry out illegal logging and illegal occupation by clearing forests into oil palm plantations. As a result, the fragmented forest area become 704.30 ha. The purpose of this study was to identifying the composition and diversity of tree species in this area. This study uses a quantitative approach using primary and secondary data. Primary data were collected using nested sampling with a large plot of 20 x 20 meters to count trees and a small plot of 10 x 10 meters to count poles. Identification of species composition was carried out by calculating the Important Value Index (IVI), while tree species diversity was calculated using the Shanon-Winner diversity index. The results showed that the dominant species at the pole level was Medang (Litsea angulana Blume) with an IVI of 28,26%, while the species that dominated at the tree level was Meranti Merah (Shorea lepidota) with an IVI of 24,43%. The tree level diversity index of 3,61 and the pole diversity index of 3,66 are included in the high diversity category, its means that the distribution of individuals for each species is evenly distributed or the number of individuals found is close to uniform. This condition also illustrates that the forest communiy is in a stable condition. Keywords: Bukit Suligi, Fragmented, Tree, Diversity

Abstract

Studies on the impact of peatland fires on agricultural land, especially oil palm, and rubber, are still limited. This study aims to calculate the total population of cellulolytic bacteria and determine the activity of cellulolytic enzymes qualitatively in each microbial isolate found and to determine the level of peatland degradation after the fire. The research was conducted by survey in the field. The research location is in the long jungle village of Tambang Subdistrict, Kampar Regency. At the same time, the laboratory analysis was carried out in the Pathology, Entomology, and Microbiology Laboratory, Faculty of Agriculture and Animal Husbandry, Sultan Syarif Kasim Riau University. Determination of sample points using the purposive sampling method, which is to choose a location per the study's objectives at 4 locations. The first location is oil palm land that is not burnt, the second is burning oil palm land, the third is unburned rubber land, and the fourth is burned rubber land. Each location was repeated three times to obtain 12 sample points for observation. Furthermore, at each observation sample point, two soil depths were observed, 0-15 cm and 15-30 cm. The total population of cellulolytic bacteria in oil palm and rubber plantations that were burned and not burned with different soil depths ranged from 5.3 x 109 cfu / g soil to 14.0 x 109 cfu / g soil. The clear zone ratio (Z / K) of 8 cellulolytic bacterial isolates observed was high criteria, namely> 1.76 (100%). The highest Z / K ratio was produced by bacterial isolates originating from burnt rubber plantations at a soil depth of 0-15 cm, namely 5.25.
