Abstract

The success of revegetation in the context of forest land rehabilitation and post-mining land reclamation is often often caused by constraints due to marginal land conditions, such as high acidity/alkalineity, low organic matter content, and low availability of macro nutrients. Mycorrhiza Biofertilizer (MB) is one alternative technology that has been reported to be able to increase the success of the rehabilitation. Forest farmers, as one of the actors in forest rehabilitation activities, do not yet have sufficient knowledge and skills in developing biofertilizer such as MB. The objectives of theis community services were to introduce and improve forest farmer about the MB, as well as to establish the demonstration plot for MB development. The result showed that field training and counseling on mycorrhiza and its benefits, as well as the manufacture of mycorrhizal biofertilizers have been carried out in Cisangku, Malasari village, Bogor Regency involving Forest Farmers Model Conservation Village (KTH MKK). The counseling and training were attended by 25 forest farmer participants. Based on the postest carried out after the implementation of counseling and training, there was an increase in farmers' knowledge about mycorrhizal and its benefits as well as procedures for developing mycorrhizal fertilizers. The participants wer also satisfied and increased their skill in preparing mycorrhizal culture materials and caring for their selves. The participating farmers were even willing to develop MB independently if they have sufficient skills and know the benefits. The increasing knowledge and skills of forest farmers had an impact on improving the quality of forest farmers in supporting forest rehabilitation and becomes an alternative of additional income.

Abstract

Ex-mining land is categorized as land with a high level of degradation. The loss of biodiversity, low soil fertility, loss of several layers of soil horizons, unbalanced texture, and even contamination can occur due to mining activities. Reforestation of mining land has been carried out with the approaches of improving the physical properties of the soil, selecting plant types, and improving soil biology in ex-gold mining land in Bogor. The addition of compost significantly increased organic matter content, C/N ratio, macronutrients (N, P, K) content, and improved soil texture. The application of Mycorrhiza and Rhizobium significantly increased the growth of forest plants such as trembesi (Samanea saman), gmelina (Anthocepalus cadamba), and ganitri (Elaeocarpus angustifolus) in ex-gold mining areas. Applying that significantly improved vegetation diversity on ex-gold mining land, including more than eight types of understory plants, and more than five plants were from the trees group. The result showed that reforestation of ex-mining land was feasible if it was carried out with a comprehensive approach.

Abstract

Providing comprehensive information on carbon stock data on all carbon pools needs to be done to plan and measure climate change mitigation efforts that are carried out. This research was conducted by analyzing spatial characteristics and estimating carbon stocks with model development. Spatial analysis is carried out to provide an overview of the distribution of spatial values that can use the built model. Estimation of carbon stock is carried out by building a carbon stock estimator model that correlates the value of remote sensing parameters with the value of carbon stocks in all carbon storage sources. The characteristics of the vegetation index value in the forest category are greater than in the non-forest category and vice versa for the distribution of the digital number average value. The model development is only carried out on aboveground biomass and belowground biomass carbon pools. The results of the analysis of the estimation of carbon stocks based on the selected model showed the potential for aboveground biomass was 5,200,841.45 tC and the potential for belowground biomass was 1,317,948.10 tC.

Abstract

Red Pelawan (Tristaniopsis merguensis Griff.) Peter G. Wilson & J. T. Waterh is a member of the Myrtaceae family. This plant is widely spread in the forests of the Bangka Belitung Islands. This study aims to determine the success of Pelawan propagation by cuttings using a mixture of cocopeat, rice husk and rice husk charcoal as well as the application of synthetic and natural growth regulators (shallot extract). This study was designed using a factorial complete randomized design with the type of media and the type of growth regulator as the factors. Cutting material in the form of shoots, 6-10 cm in size, from a 2 - 4 years old pelawan tree in Pelawan Forest, Central Bangka. Synthetic hormones used the commercial brand Root-Up with a concentration of 15 g/10 ml, and natural hormones used shallot extract with a concentration of 200 g/300 ml of water. The results showed that the use of the two media did not have a significantly different effect, except for the percentage of surviving cuttings. Within 3 months of observation, the aplication of natural hormones, shallots, the cuttings which were able to root reached 4% with a root length of 16.5 mm, and to be sprouted as much as 2% with a shoot length of 5.5mm. Although the growth of cuttings treated with shallots was significantly lower than cuttings treated with synthetic hormones, the survival rate of cuttings reached 68% with shallot hormone treatment, indicating that shallots have the potential as an alternative natural hormone to stimulate the growth of T. merguensis cuttings.

Abstract

Post-mining land revegetation is one of PT. ANTAM UBPE Pongkor committed to restoring the impact of both mining and non-mining activities in its concession area, comprising 3 locations (GHSNP Critical Land, Cepu Landslide Block, and Mount Puntang Block). This study aimed to identify the species composition, diversity, evenness, and richness of tree species. This research was carried out by observation at 12 locations following checkered paths, parallel to intersecting contour lines. Observation sample plots for the tree, pole, sapling, and seedling were measured on areas 20x20 m, 10x10 m, 5x5 m, and 2x2 m, respectively, with maximum sampling intensity of 10%. Vegetation composition and structure were observed by measuring the Importance Value Index (IVI), the Biodiversity Index (H'), Species Evenness Index, and Richness Index (Dmg). Sixty species of trees were found in the IUP area of PT. ANTAM UBPE Pongkor, in the growth phase of trees, saplings, poles, and seedlings, dominated by Puspa, Rasamala, Waru Lot Mara, Calik Angin, Huru, Kaliandra, and Ganitri, which were spread almost evenly in each location, with IVI value of 50% -300 %. Species diversity with a high category (H' =3.23) was found in the natural forest in the Baching Plant, the medium category was in the cepu landslide block reclamation area (2.67), while the small diversity was in the reclamation area around the administration office (1.61). The evenness index (E) ranged from 0 to 1, and the species richness index (Dmg) ranged from 0 – 7.58, indicating that the IUP area is quite diverse regarding its biodiversity.

Abstract

In addition to providing benefits, mining activities can result in physical, chemical, biological and marginal changes for plant growth. Criteria of plants used for revegetation of land mines are rapidly growing in the neighborhood marginal, allowing other types of grow on the land, producing fruits that are easily spread by birds, and producing a litter easier undergoing decomposition. This research aims to know the biodiversity and natural vegetation types of suitability identification for revegetation land post-mining tin. Observation of post-mining land was carried out to identify the physical and chemical properties of the soil and the type, density, and distribution of vegetation in the observation plots. Analysis of the suitability of vegetation types with rehabilitation land refers to the criteria in Permenhut No P.4/Menhut-II/2011 with modifications. Soil texture on former tin mining land was dominated by sand, is acidic, and has low nutrients. There were 35 types of plants found, ten species of trees and three types of shrubs among them, which have the potential to be used in revegetating post-tin mining land, namely. i.e., the Acacia mangium, Syzygium buxifolium, Syzygium racemosum Blume, Schima wallichii, Trema orientalis, Eugenia sp., Alstonia angustifolia, Ficus padana, Alstonia scholaris, Vitex pinnata L, Syzygium sp, Melastoma malabthricum dan Melastoma polyanthum.

Abstract

Social forestry is a sustainable forest management system implemented in state forest areas or private forests. Local communities or customary law communities implement customary forests as the main actors in improving their welfare. The Social Forestry Program aims to enhance community welfare through empowerment patterns while still being guided by sustainability aspects. Communities around forests are given equal and broadest opportunities to apply for forest area management rights to the government. Communities can cultivate and benefit from forests in environmentally friendly ways. One way to utilize forest areas is to make them tourist attractions. Good management of tourist attractions requires skills in planning and implementation. Garut Regency is one area that has many sustainable forest locations that have been used as tourist locations and have the potential to increase people's income, but these tourist attractions still need to bestill need to be well promoted to the wider community. Therefore, training in creating tourism promotional content is required in order to strengthen the knowledge and skills capacity of social forestry groups in managing tourism potential in the Garut Regency. This community service activity aims to increase the knowledge and skills capacity of the Forest Farmers Group (KTH) in creating promotional content for tourist attractions. The result of this activity is that KTH members are able to create promotional content for tourist attractions using the Canva and CapCut applications so that they can increase the number of visitors to their tourist attractions.

Abstract

Tailings are the wastes resulting from mining activities in the amalgamation of mine ore from the ground, with extreme characteristics such as a sand-dominated texture, high Pb heavy metal content, very low availability of carbon and macro nutrients. Consequently, the plants may not able to grow well in the tailings. The application of Arbuscular Mycorrhyza Fungi (AMF) is expected to increase the ability of forest plant seedlings to grow and develop in tailings media. The research was carried out in a greenhouse using johar (Cassia siamea Lamk) seedlings which were inoculated with AMF inoculum: Glomus manihotis, Glomus etunicatum, and mix inoculan (mycofer), and planted in tailings media collected from Pongkor gold mine for 8 weeks. Johar seedlings were able to grow in tailings media and AMF colonization to the seedlings was observed. The compatibility of multi-species inoculum, mycofer, is higher than single AMF inoculum. The height, diameter and biomass growth of johar seedlings in tailings media significantly (p<0.05) increased with AMF inoculation. Johar seedlings have a high dependence on AMF, on tailings media, undicated by value of MIE > 50%, suggesting that the AMF application to johar is very necessary for revegetation activities in tailings media.
