Abstract

Public perception is important in implementing Forest and Land Rehabilitation (FLR) in forest areas where tenure conflicts are thick. The research aims to analyze community perceptions of the implementation of FLR based on local superior plants in Girimulyo Village, Marga Sekampung District, East Lampung Regency. Data collection was carried out using a questionnaire of 30 respondents determined by purposive sampling. The collected data was analyzed descriptively to analyze farmers' perceptions and their relationship to social, economic and ecological aspects. Public perception of FLR activities based on forestry plants (Trees) is included in the medium category. The public's perception of FLR based on the superior Siger avocado crop in terms of social, economic and ecological aspects is in the high category. The community realizes that FLR for local superior plants is more profitable than FLR based on forestry plants. It is necessary to increase human resources in the Mulyo Lestari Agro Forest Farmers Group in order to facilitate the administrative management process

Abstract

Local knowledge of rubber latex processing is important for village communities that depend on rubber plants for their livelihood. This research aims to determine the processing of rubber latex in agroforestry carried out by the community in Menggala Mas Village, Lampung Province, Indonesia. This research approach is qualitative. Data was obtained by observation, in-depth interviews, and documentation studies. Then, the data was processed by making data transcripts, coding, categorizing, drawing temporary conclusions, triangulating, and drawing conclusions so that the results obtained could be analyzed to determine the data processing. Local communities carry out rubber in agroforestry. The research results showed that three applications of agroforestry planting patterns were found, namely alley cropping (alley pattern), Trees along border (fence pattern), and random mixture (random pattern). The dominant combination in alley cropping is rubber-pulai, and rubber-mentru-afrika wood. The dominant combinations in Trees along the border are rubber-acacia, rubber-jackfruit-cempedak, rubber-petai-teak. The dominant combinations in the random mixture are rubber-jengkol, rubber-petai-jengkol-acacia, rubber-jackfruit-cempedak, rubber-pulai-noni-jengkol, rubber-banana-gadung-sungkai. The rubber latex processing process in agroforestry is carried out traditionally, starting from the tapping process, sap acidification, sap harvesting (napeu), sap separation, and sales and harvesting of agroforestry crops. The community's local knowledge has been passed down from their parents to reduce the costs of processing rubber latex from expensive materials so that the community can gain more profits. This has been proven if local communities can manage their land well, which can become a long-term source of livelihood. The government needs to assist with strategies for processing rubber latex as well as managing rubber agroforestry land to increase farmers' knowledge and harvest yields

Abstract

Mangroves are a unique ecology that resides in places with salinity, which are inundated at low tide when there is no flooding and at high tide. Mangrove forests that are increasingly damaged cause the quality and quantity to decrease. Using different species of fungi that can accelerate the growth of mangroves is one attempt to increase and get high-quality mangrove seeds. This study aims to shed light on the fungi that can dramatically improve the growth of Avicennia marina seedlings. Mangroves can absorb organic and non-organic materials produced by decomposing microorganisms, which come from leaf litter or other decomposed materials. In this experiment, several fungal species were used, including Aspergillus niger, Aspergillus sp. 2, and Aspergillus sp. 1. The findings demonstrated that the fungus might speed up A. marina seedling growth. The plant's height, diameter, leaf width, and total dry weight were all altered as a result. Based on the study's findings, it can be said that Aspergillus niger provided the best growth for A. marina seedlings

Abstract

The sustainability of mangrove forests really depends on the involvement of communities in the areas surrounding the mangrove forests. If the mangrove environment is to be used in the long term, it must be managed and preserved. This research aims to determine strategies for sustainable mangrove management in Sumber Nadi Village, Ketapang District, South Lampung Regency. The method used in this research is a qualitative approach. Data was obtained through in-depth interviews involving key informants who were selected and determined using snowball sampling and analyzed using SWOT analysis of Strengths, Weaknesses, Opportunities and Threats, which includes Natural Resources and Human Resources. The results of this research show that the total value of the influence of internal strategies has a value difference of 0.32. Likewise, the external value has a difference of 0.11. Then, combining the two values of the difference between strengths and weaknesses and opportunities against threats, a coordinate point is obtained, namely the coordinate point (0.32; 0.11). The strategy that must be implemented in Sumber Nadi Village, Ketapang, is to support aggressive growth policies (growth-oriented strategy). Mangrove forest management strategies, as in the quadrant above, show a favorable situation. The relevant agencies, management and the community should support this management development strategy so that it can maintain the potential of existing mangroves

Abstract

Mangrove forests are important in climate mitigation, particularly for their greatest carbon storage. Rhizophora apiculata, a mangrove species with numerous advantages, is frequently employed in restoration activities. Monoscpecies restoration activities are well known, although information on floristic composition and carbon uptake must be available. The objective of this research was to investigate the floristic composition and carbon stock of R. apiculata in the Pasar Rawa Village restoration area, Langkat Regency, North Sumatra Province. This study employed the vegetation analysis approach and carbon estimates based on diameter breast height (DBH) and total vegetation height. The study's findings indicate low floristic diversity in the research area. At the seedling stages, the greatest IVI (113.68%) was discovered in Achanthus ilicifolius, and the only species found in the sapling stage with an IVI value of 200% was R. apiculata. The study of diversity indices revealed very low values at the seedling stage (H'= 0.806) and no diversity at the sapling stage. The total carbon stored estimation in R. apiculata stands relatively low, at 8.56 tonnes/ha. The absorbed carbon produced by R. apiculata is 31.42 tons/ha with a CO2 absorption of 3.141 g/m2 and is classified as relatively low

Abstract

Avocado is a multifunctional plant that can be utilized in all parts. The growth of avocado and its yield can be achieved by fulfilling requirements for the growth and maintenance of the plant well. Planting on dry land requires the addition of organic fertilizer and optimal water requirements to increase organic matter content and plant fertility. This research aims to obtain the optimal dosage of compost and watering intervals for the growth of avocado (Persea americana). The research was carried out in the Greenhouse Faculty of Agriculture, Universitas Sumatera Utara. This research used a factorial completely randomized design (F-CRD) with the addition of compost fertilizer doses (K0:0 kg, K1:0.5kg. K2: 1 kg. K3: 1.5 kg and K4: 2 kg) and watering intervals (A1: once a day. A2: once every three days. A3: once every five days and A4: once every seven days) with parameters of observation of height, diameter, top fresh weight, root fresh weight, top dry weight and root dry weight. The results showed that the interaction of compost and watering intervals significantly affected the height and diameter increase, root fresh weight, and root dry weight of avocado plants. The interaction of giving 1.5 kg of compost and watering intervals every day had the best effect on the growth and quality of avocado seedlings

Abstract

Lignin, a naturally abundant aromatic polymer of natural origin, offers numerous desired intrinsic properties belonging to rich functional groups. However, the lignin properties vary influenced by the source of biomass (hardwood, softwood, and herbaceous) with different monomer unit proportions, delignification methods, and isolation techniques. To extract lignin, two routes have been introduced i.e. cellulose first fractionation and lignin first fractionation. The focus of this review is revisiting the strategy of cellulose first fractionation in which lignin is mainly present as a side product of the delignification process via the sulfur-bearing process and the non-sulfur-bearing process. After that process, the isolation process was employed in black liquor as a by-product of the process. By this route, technical lignin is produced with the potential to convert into biomaterial feedstocks. The main property concern of this lignin is its condensed structure which requires further modification for specific purposes. Physical and chemical modification can be introduced to increase the reactivity of lignin to widen the application

Abstract

Evaluating land suitability for Aleurites moluccana in community agroforestry land within Langkat District, North Sumatra, is crucial for promoting sustainable development, enhancing livelihoods, and preserving ecosystems while honoring local traditions and cultures. The primary objective of this research was to evaluate and map the land suitability for A. moluccana within Langkat District, located in North Sumatra, Indonesia. To gather the necessary data, this study employed a survey method, involving the collection of soil samples from ten distinct land units within the field. The assessment of land suitability was carried out using the matching method. Geographic Information System (GIS) technology was utilized to create maps illustrating the distribution of land suitability, while a Global Positioning System (GPS) was employed to accurately record the coordinates of the collected soil samples. The findings revealed that within Gunung Ambat, Simpang Kuta Buluh, Rumah Galuh, and Telagah Village, the actual land suitability classes for A. moluccana were classified as moderately suitable (S2) and marginally suitable (S3). The prevailing limiting factors in this region were temperature (tc) and the characteristics of the root zone medium (rc). Consequently, this influenced the potential land suitability classes for A. moluccana, resulting in classifications ranging from highly suitable (S1) to moderately suitable (S2) and marginally suitable (S3). By implementing land suitability evaluation for A. moluccana in community agroforestry land, promoting sustainable land use, enhancing livelihoods, and conserving natural resources.
