Abstract

 Increased soybean production  is  competing with the extension of the  use of agricultural land for  non- agricultural needs. Therefore the future expansion of agricultural land can only use marginal lands such as peatlands, wetlands and tidal lands. This paper discusses the growth and production of soybean varieties Anjasmoro in saline environments. Varieties Anjasmoro have total leaf area and the percentage ratio of the canopy  which  is  not  significantly  different  from  the  other  varieties  tested  except  Kipas  Merah.  In  the production of components, seed weight Anjasmoro 100 seeds varieties including higher and statistically the same as the varieties Kipas Putih dan Kipas Merah

Abstract

Medan City is a Metropolitan City with a high population growth rate, in line with the growth rate of regional development. These problems spur the occurrence of land use change. The need for land for residential locations, transportation infrastructure facilities and others will impact the reduced availability of green open space as an oxygen producer in the city of Medan. This study aims to examine the distribution of green open space, estimate the need and adequacy of green open space, and develop directions for developing green open space. This research was conducted from January to completion, using the method of interpretation and analysis of spatial data from quick bird images taken from the SAS Planet application, and calculations were carried out using the Gerarchic formula to determine oxygen demand. The results showed that the area of green open space in Medan City was 86.27 km2 (33%), and non-vegetated/non-green open space was 178.83 km2 or equivalent to (67%) of the Medan City area of 265.10 km2. The oxygen plants produce in green open spaces is 4,367,418.75 kg/day. Meanwhile, the oxygen demand in Medan City is 5,150,425.98 kg/day, and when converted into green open space, it is 101.74 km2. Directions for the development of green open spaces can be carried out in several ways, namely managing green spaces, synergizing the natural and artificial environment, implementing a low-cost transportation system, empowering population policy strategies, utilizing water and energy resources, maintaining environmental health based on city planning that favours development principles sustainable.Keywords: Green open space, Oxygen, Quickbird Image, Medan

Abstract

Mount Sipiso-piso is an Old Volcanic Mountain and part of the Lake Toba Catchment Area (DTA). The location of the Forest on Mount Sipiso-piso is unique because the site of the Forest is at the top of Mount Sipiso-Piso. The area below the mountain is a dense Forest that stands in the peak area of Mount Sipiso-Piso has a role in maintaining water flows in the Mount Sipiso-Piso area, becoming a place for rainwater absorption, and maintaining ecosystem stability so that erosion or landslides do not occur in vulnerable areas. This study aimed to look at the diversity and evenness of Mount Sipiso-piso Forest vegetation types. Data analysis techniques include Important Value Index (INP), Diversity Index (H'), and Evenness Index (E). The results showed that 20 families and 23 plant species from 1539 individuals were found in the field. The Important Value Index (INP) indicates that different individuals dominate the forest community at each level. The index of the diversity of Mount Sipiso-Piso Forest vegetation is categorized as moderate in the saplings, poles, and trees class and the low category in the undergrowth, woody shrubs, and seedlings class. For the species evenness index, the category is expected in the undergrowth and seedling class, the medium type is in the woody shrub and tree class, and the high sort is in the sapling and pole class.Keywords: Sipiso-Piso Mountain, Forest, Vegetation, Diversity, Evenness.

Characteristics of the Location and Recharge Pattern: Data, Analysis and ResponseABSTRACT. Infiltration as a movement of water could determine a large amount of water which could move over the soil surface to the river, and the water that went into the ground. The information of water infiltration in watershed was required to make decision about sustainable water resources. On the other hand, the infiltration was dynamic, that was why it was interesting to be analyzed. The purpose of this study was to determine differences in volume that occurred in the watershed catchment of Krueng Peusangan. Having viewed the differences and similarities location against variabel temperature, evapotranspiration, moisture, discharge, rainfall for the fivepoint, watershed locations of Krueng Peusangan using Principal Component Analysis (PCA). Based on PCA, the location was selected to analyze the volume of leach discharge measured during 2008-2011 in Wih Nareh and Kr. Teumbo. Absorption volume indicated that occurred instable infiltration at Kr. Teumbo. It needed guidelines for land use arrangement and forest function, especially in the recharge area. So, it could maintain the balance of hydrological cycle, groundwater quantity and quality properly.

Abstract

The behavior of visitors littering in coastal tourist parks has resulted in the generation of plastic waste, which, in turn, poses a significant risk of polluting the ocean. This issue arises due to the absence of a deliberately constructed visitor littering control system by the park management. This paper explains that a visitor littering control system in tourist parks can be established by the management through participatory and persuasive approaches, without causing resistance from visitors. The method employed is through active engagement. Park managers and staff across all levels, particularly those who interact directly with visitors, are collaboratively involved in developing a shared understanding. This is achieved through Focus Group Discussions (FGDs), which address the rationale behind encouraging visitors to manage their own waste, facilitated by a dedicated team. Through FGDs, complemented by educational materials on the environmental impact of plastic waste and the development of a Procedural Manual for establishing a visitor littering control system, along with continued support, the park management succeeded in creating an environment where staff systematically and collectively persuade visitors while providing waste bags (disposal points) to prevent littering. The results of this initiative demonstrate that the visitor littering control system in the Mangrove Tourism Park has begun to take shape, characterized by a shared commitment and awareness to tackle waste management issues, as well as an increased understanding among the park management of the environmental hazards posed by plastic waste.

Abstract

This community service examines the empowerment and independence of Desa Binaan Bagan Kuala in the Tanjung Beringin Sub-district of Serdang Bedagai Regency, North Sumatra, through the implementation of ecotourism, ecoprint development activities, appropriate waste management, and malaria eradication initiatives. The objectives of this research are to assess the socio-economic impacts of these initiatives on the local community and evaluate their contributions to sustainable development. The research utilized a mixed-methods approach, collecting both qualitative and quantitative data from 150 households in the village through surveys and interviews. The findings indicate that ecotourism initiatives have generated a 30% increase in local income, attracting over 1,000 visitors annually and creating approximately 50 jobs. The ecoprint development activities have empowered 40 local artisans, resulting in a 25% increase in their income and the production of over 2,000 ecoprint items in the past year. Moreover, the implementation of appropriate waste management practices has led to a 40% reduction in local waste pollution, with 75% of households participating in waste segregation and recycling programs. Malaria eradication efforts have also shown significant results, with reported malaria cases decreasing by 60% over the last two years due to community engagement in health education and the distribution of insecticide-treated nets. This comprehensive approach to community empowerment not only enhances economic independence but also promotes environmental sustainability and public health. The success of these initiatives demonstrates the potential for rural communities in Indonesia to achieve sustainable development through participatory strategies that address both economic and health-related challenges.

Abstract

Social forestry (PS) is a form of sustainable forest management within state forest areas where local communities act as the leading actors to improve welfare, ecological balance, and socio-cultural dynamics. Although PS has been promoted to reduce poverty, increase local income, and strengthen forest conservation, many groups still face challenges in management, compliance, and financial sustainability. At the UPTD KPH IX Panyabungan, several social forestry groups have obtained legal approval but continue to struggle with fulfilling regulatory performance indicators, particularly in business development, area management, and financial contributions to the state (PNBP). This research was conducted in the North Sumatra Forest Management Unit Regional IX Panyabungan, involving four active social forestry groups (KPS): KTH Permata Belantara and KPS Sampean Jaya (HKm), KPS Globe Mangrove Indah (HD), and KPS Koperasi Rizki Jaya (HTR), selected from a total of seven groups at the site. This study aims to analyze the performance of KPS as PS approval recipients. The research employed a qualitative approach using field observations, in-depth interviews, and document analysis, with evaluation criteria and indicators based on the Regulation of the Minister of Environment and Forestry No. 9/2021. The novelty of this study lies in evaluating both the economic impacts and compliance performance of KPS after PS approval, while most previous studies mainly emphasized ecological or participation aspects. The results show that KPS fulfilled institutional indicators and generated additional income: KTH Permata Belantara (Rp. 31.9 million/year), KPS Sampean Jaya (Rp. 17.75 million/year), and KPS Gubeg Mulyoharjo Indah (Rp. 36.96 million/year). They also received capital support and planted 18,293 trees over three years. However, optimization is still needed in area management, business development, and non-tax state revenue (PNBP) payments. Thus, stronger institutional support, capacity building, and monitoring are required to ensure that PS not only meets administrative targets but also delivers measurable improvements in community welfare and forest sustainability.
