Abstract

Grenjeng River is one of the irrigation water resources which is currently polluted by waste from industrial, livestock and domestic activities. This study aims to assess the quality and index of water pollution based on physical-chemical and biological parameters in the Grenjeng River, Boyolali Regency. Sampling of river water was carried out in dry and rainy seasons which were taken at three observation stations (upstream, middle stream and downstream). Results from laboratory analysis were compared with water quality standards according to Government Regulation No.82/2001, and quality status was based on the Pollution Index method in accordance with the attachment to Minister of Environment Decree No.115/2003. This study shows that BOD of 53-5.7 mg L-1, COD of 49-510.5 mg L-1 and total coliforms of 540-2,400,000 mLin dry season have exceeded the quality standard water classes, while in rainy season total coliforms 24,000-240,000 mLhave exceeded the standard water for all water classes. The pollution index of the river water in dry season has reached polluted to extremely polluted levels and the index of the river water in rainy season has reached moderately polluted to polluted levels. This condition shows that the practice of dumping waste into river bodies can directly affect river water quality. The irrigation water source for agricultural must comply with irrigation water quality standards so that is suitable as irrigation water for plants. Environmentally friendly approach is needed to prevent worse pollution, which is done by increasing public awareness and business actors in managing liquid waste by making the integrated wastewater treatment system.

Abstract

Climate change affects the existence of agricultural production from time to time, especially by increasing the concentration of CO2 in the atmosphere which has an impact on increasing temperatures. Temperature as an environmental factor influences plant physiological processes, which in turn affects plant production. In addition, climate change causes high fluctuations between the intensity of rain and drought, giving rise to La-Nina and El-Nino phenomena. This condition is a threat to food security and thus stakeholders are obliged to take concrete actions in the form of mitigating the impacts of climate change. Agroforestry is the first choice of agricultural cultivation technology by promoting trees as ecosystem service providers in the form of microclimate and soil (nutrients and water) which are beneficial for cultivated crops (seasonal). This cultivation technology also increases the potential of suboptimal land in Indonesia, which is quite extensive. Agroforestry systems improve suboptimal land quality and support climate change adaptation and mitigation efforts. Some food crops such as upland rice, soybeans and maize can be cultivated in agroforestry systems. Although the production of food crops in agroforestry systems is relatively lower than in open areas, agroforestry is considered to have the ability to support food security in terms of soil and water conservation, diversification of land use and the adequacy of micronutrients.

Abstract

Water clover is an important weed that causes a decrease in rice yields by 15-42%. This study examined the effects of water clover density andNPK fertilizer application on rice yields. This study was arranged in a complete randomized block design with two factors. The first factor was water clover density with three levels, consisting of no water clover, one water clover, and two water clover. The second factor was the application of NPK, which was applied to the surface, submerged in 3, 6, and 9 cm—performed with three replications. Water clover density affected the number of rice panicles, the number of rice grains per panicle, the weight of 100 seeds, rice biomass, and water clover biomass. The application of submerged NPK affected rice biomass. The application of NPK on the surface reduced the highest rice biomass. Two water clovers per rice plant reduced the number of rice panicles by 39% compared to without weeds. Rice biomass decreased by 40% and 50% at weed density of one and two water clover weeds per rice plant, respectively. The higher the density of clover weeds, the higher the decline in harvest yields and the higher the biomass of clover weeds.

Abstract

Background: Indigofera tinctoria, commonly known as true indigo, is a plant widely used in the textile industry for its natural indigo dye, which produces a rich blue color for fabrics. I. tinctoria, known for its natural bluish-purple dye, generates 10% dye and 90% waste during extraction, requiring effective waste management. This study aimed to optimize organic fertilizer and mycorrhiza doses from I. tinctoria  waste for enhancing soil fertility in arid regions. Methods: The study was conducted from May to December 2020 in Puron Village, Bulu District, Sukoharjo Regency. A factorial Completely Randomized Block Design (CRBD) with 2 factors was employed. The first factor consisted of 5 levels of I. tinctoria  organic fertilizer treatments: 0, 100, 200, 300, and 400 g per plant. The second factor included 3 levels of mycorrhiza treatments: 0, 10, and 20 g per plant. Variables observed included mycorrhizal infection on roots, plant growth rate, and yield (fresh leaf and shoot weight of I. tinctoria ). Data analysis utilized ANOVA at a 5% significance level followed by Duncan Multiple Range Test (DMRT). Results: The results indicated that organic fertilizer from natural dye waste at a dosage of 200 g per plant increased the percentage of mycorrhizal-infected roots and boosted shoot weight by 63.27% at 8 weeks after planting (WAP). Mycorrhiza at 10 g per plant increased mycorrhizal infection percentage and enhanced shoot weight by 45.98% at 4 WAP. The combination of I. tinctoria  extraction waste organic fertilizer at 200 g per plant and mycorrhizal at 10 g per plant showed interaction, significantly increasing the growth of root nodules of I. tinctoria by 84.04% at 12 WAP. Conclusion: The integration of organic fertilizer derived from indigo dye waste and mycorrhiza presents a promising strategy for enhancing I. tinctoria  growth and productivity. Novelty/Originality of this Study: This study is distinctive in its demonstration of the effective use of I. tinctoria  extraction waste as an organic fertilizer, aligning with zero-waste principles and contributing to improvements in plant growth and soil fertility. Furthermore, it investigates the synergistic effects of mycorrhizal associations on enhancing nutrient absorption and overall productivity of I. tinctoria , an aspect that has not been thoroughly explored in prior research.

Abstract

Forest management activities inevitably affect environmental functions and community well-being, necessitating rigorous impact monitoring to improve management practices. The Indonesian National Forest Stewardship Standards (NFSS) provide structured guidelines to balance timber production with environmental protection. This study evaluates the comprehension and application of these standards in forest harvesting planning, implementation, and impact assessment. A quantitative descriptive method was employed, integrating questionnaires, field observations, and interviews with field staff from a Forest Stewardship Council (FSC)-certified forest concession in West Papua, Indonesia. Respondents included staff involved in forest planning, production and logging road construction, silviculture and environmental monitoring, and community development. Data were collected using NFSS-based questionnaires and analyzed using the Likert scale method. In addition, triangulation was conducted via field observations at harvesting sites, document reviews (forest management procedures, High Conservation Value report, Social Impact Assessment report, and Environmental Management and Monitoring Plan report), and interviews to validate questionnaire findings. The results show an average Likert score of 83.91% across five key variables (baseline environmental data, Reduced Impact Logging (RIL) map presence, RIL implementation, human resources, and impact monitoring and adaptation), indicating a strong understanding of NFSS standards. However, challenges remain in enhancing community engagement, implementing best management practices, strengthening supervision and impact monitoring techniques, and developing adaptive strategies for sustainable forest management.

Abstract

Tawangmangu District, Indonesia, is located in a highland area with a cool climate and is predominantly composed of Andisol soil types, offering great potential for the development of potato crops (Solanum tuberosum L.). This study aims to examine soil physical properties suitable for potato cultivation, analyze the distribution of these properties across different slope gradients, and identify appropriate soil management strategies for the Tawangmangu area. The research employed a descriptive-exploratory approach, utilizing land map units (LMUs) that were determined through the overlay of soil type maps, rainfall data, slope gradients, and land use. The overlay resulted in 5 LMUs and 25 sampling points. Observed soil physical parameters included texture, porosity, permeability, consistency, effective soil depth, coarse material, and drainage. The land suitability assessment showed that LMUs 1, 2, and 3 were classified as S3-oa, limited by drainage, while LMUs 4 and 5 were classified as S3-oa,rc, limited by both drainage and effective soil depth. Slope gradient significantly affected moisture content (p = 0.022), bulk density (p = 0.037), particle density (p = 0.048), porosity (p = 0.032), effective soil depth (p = 0.001), and coarse material content (p = 0.032). Recommended land management efforts include the addition of organic matter, manual tillage for shallow soils, and the application of eco-drainage techniques to improve soil physical suitability for potato cultivation in Tawangmangu.
