Abstract

Revegetation is an important part of reclamation activities of mined land, partly due to potential CO2 absorption from theatmosphere, particularly through photosynthetic reactions. This research was aimed to calculate the amount of C absorbedby two major fast growing legume species in most reclaimed mined lands in Indonesia, mangium (Acacia mangium) andalbizia (Paraserianthes falcataria) at four years of age. Three tree samples of each species were destructively taken fromthe reclaimed mined land belong to PT Bukit Asam (PERSERO) Tbk, Tanjung Enim, South Sumatra to obtain plant biomassproduction of both above and below ground. The above ground plant biomass was separated into leaf, branches & twigs,and stem. All these components and the below ground biomass (roots) were then weighed for fresh weight determination.About 200 g of these tree components were dried in an oven at 70oC to obtain their dry weights, and then ground into 60mesh diameter for C analysis using wet destruction method of Walkley and Black. The results showed that up to the fourthyear, mangium sequestered C almost double of that sequestered by sengon stands, 21.66 and 10.35 kg C/tree respectively.

Abstract

Since the beginning of agriculture revolution several thousand years ago, human has distributed food plant species far beyond their natural range. The tendency of agriculture practice to plant certain “superior” species and varieties has led to the homogenization of dominant food plant commodities worldwide. Local species and varieties are marginalized with the introduction of exotic species, resulting in the decline of genetic diversity. The objectives of this study were: 1) to determine the species richness of vegetable plants in three traditional markets in Bengkulu City, 2) to know the species composition of the vegetable plants in those markets, and 3) to determine the species similarity index among the three markets. Data were gathered by recording all species of vegetable plants in the markets. The data were, then, analyzed to determine the species richness, species composition and species similarity among the three markets. The results showed that 1) the total number of vegetable plant species in the three markets was 50, consisting of 23 families, 2) the introduced species dominated the composition of vegetable plants, and 3) the similarity index among markets were >90%. These results confirm the tendency that food plant species composition is dominated by few species only, and show that the species composition of vegetable plants among markets in Bengkulu city was highly similar. Keywords: biodiversitas, ethnobotani, ketahanan pangan. Sejak dimulainya revolusi pertanian beberapa ribu tahun yang lalu, manusia telah memperluas penyebaran jenis tanaman pangan sampai jauh dari wilayah sebaran aslinya. Kecenderungan praktek pertanian yang menanam jenis-jenis dan varietas “unggul” menyebabkan terjadinya keseragaman jenis dan varietas tanaman yang mendominasi komoditas tanaman pangan di seluruh dunia. Jenis-jenis dan varietas tanaman lokal banyak yang tersingkir oleh jenis-jenis introduksi, sehingga terjadi penurunan keragaman genetis. Penelitian ini bertujuan untuk menghitung kekayaaan jenis dan komposisi jenis tanaman sayur segar yang terdapat di tiga pasar di Kota Bengkulu. Data jenis sayuran diperoleh dari pencatatan di lapangan. Data diolah untuk menghitung kekayaan jenis tanaman, menentukan dominansi jenis tanaman berdasarkan frekuensi ditemukannya, dan menghitung indeks kemiripan jenis antara ketiga pasar. Hasil penelitian menunjukkan bahwa 1) jumlah seluruh jenis tanaman sayur di tiga pasar adalah 50 jenis yang terdiri dari 23 suku; 2) jenis-jenis tanaman yang mendominasi komposisi jenis tanaman sayur di pasar adalah jenis-jenis introduksi, dan 3) indeks kemiripan komposisi jenis tanaman sayur antara pasar > 90%. Hasil penelitian ini mengkonfirmasi kecenderungan bahwa komposisi jenis tanaman pangan didominasi oleh hanya sedikit jenis tanaman, dan menunjukkan bahwa komposisi jenis tanaman pangan antar pasar di Kota Bengkulu sangat mirip. Kata kunci: biodiversitas, ethnobotani, ketahanan pangan

Abstract

Visitor perceptions are very important in developing natural tourism on post-mining land. Post-mining land often offers the potential to be developed into a unique tourist destination with its own characteristics. One of the post-mining natural tourist attractions that is very interesting for visitors in Central Bengkulu Regency is the Kandis Hill natural tourist attraction. This research aims to determine visitor perceptions in the development of Kandis Hill natural tourism, Central Bengkulu Regency. The research uses qualitative descriptive methods. Research variables include beauty, cleanliness, security, spatial planning, staff reception, public facilities, signal conditions, road access, transportation, accommodation, security. Primary data was obtained through observation and interviews using a questionnaire, then analyzed using a Likert scale. The results of the research were that the highest visitor perception regarding beauty reached 94% with an adequate category and the lowest regarding cleanliness and staff reception with a score of 20% in the inadequate category. Another thing that needs attention is public facilities that are damaged and not functioning. Currently, the management of Kandis Hill is still in the hands of the regional government. For this reason, the government needs to empower the community around the Kandis Hill area to manage the area so that it is better managed and can develop the economy of the community around the area

Abstract

Soil Quality Index (SQI) assessment is a crucial parameter for evaluating the effectiveness of land reclamation objectives. This research aimed to analyze trends in soil quality changes across various stages of post-coal mining reclamation. This research was conducted in June 2024 at sites with varying soil ages at PT Inti Bara Perdana and in natural forest areas. This research employed descriptive-exploratory methods and involved open-field surveys. Sampling was conducted using purposive sampling at locations representative of the conditions at each site. Principal Component Analysis (PCA) was utilized to identify key indicators and determine the SQI. The results demonstrated that post-mining land reclamation significantly improved the physical, chemical, and biological quality of the soil. While the reclaimed soil quality has not yet fully reached the level of natural forest soil, the reclamation process exhibits strong potential for ecosystem recovery. SQI analysis revealed an increasing trend in soil quality as the reclamation age advanced. Linear variable analysis indicated a positive correlation between reclamation age and SQI development. Reclaimed areas aged 7 and 11 years exhibited SQI values exceeding 0.5, signifying successful reclamation and ecological sustainability.

Abstract

Indonesia faces a significant challenge in land rehabilitation, with approximately 8.7 million hectares of degraded land and 4.5 million hectares of severely degraded land, according to data from the Ministry of Environment and Forestry (KLHK) in 2022. Large-scale rehabilitation efforts are urgently required, one of which is undertaken by the Mahakam Berau Watershed and Protected Forest Management Agency (BPDASHL Mahakam Berau). The success of land rehabilitation is strongly influenced by the composition of species and the diversity of seedlings used in the process. This study aims to examine the diversity and composition of seedling species provided by BPDASHL Mahakam Berau from 2013 to 2017 and explore the rationale behind species selection. Data were collected through questionnaires and analyzed using both quantitative and qualitative approaches. The findings reveal that 33 seedling species were utilized, comprising 24 native and nine introduced species. The Shannon diversity index (H') ranged from 1.23 to 2.19, indicating a low to moderate level of species diversity. The most dominant species was Rhizophora sp. (45.14%) from the Rhizophoraceae family, followed by Shorea sp. (24.17%) from the Dipterocarpaceae family. Seedling availability emerged as the primary criterion for species selection, reflecting logistical practicality and cost-effectiveness in seedling procurement for rehabilitation programs.
