Abstract

Policy reforms and research on agricultural ecology need to be intensified to reduce land degradation and the massive ecological and chemical impacts of soil chemical pollution. This is related to the increase in population that requires clothing, food, and welfare. Furthermore, although there has been a shift toward a form of agriculture with high-added value. This problem must be solved by diversifying efforts, applying ecology to agricultural cultivation land, and making breakthroughs in making organic fertilizers with various sources and environmentally friendly ways. This is rational and can be done by involving the industry, universities, and farmer groups who are smart and productive. Regarding farming diversification, The results obtained are by the solutions offered, farmers can make liquid organic fertilizers by utilizing water measuring 200 nm to 10 m of Micro-Nano-Bubbles (MNBs). This is following the concept and is the application of Econobiotechnology. Knowledge before participating in the training in making fertilizers Organic Liquid is 74%, while knowledge after attending training on making Liquid Organic Fertilizer is 91%. The interest in learning and making Liquid Organic Fertilizer is 40%.

Abstract

The disaster that occurred in the Mentawai Islands district has become a cultural shaping factor. Thus, this forms local wisdom to survive and adapt to natural disasters that often occur. This study aims to determine the role of local wisdom in the Mentawai people in disaster mitigation efforts. This type of research is research that uses a systematic review method (Systematic Review). The stages of literature collection refer to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. This study shows that there are several local pearls of wisdom in the form of disaster mitigation that are owned by the Mentawai people, including the arat sabulungan belief that teaches humans to treat nature, plants, water, and animals like him. In addition, there is an Umma (Mentawai Tribe Community House) which was built in a collaborative manner made from natural materials obtained from the forest with the building construction being strong and flexible enough so that it can withstand earthquake shocks. Apart from that, there is the Mentawai Folklore (Sitakkigagailau and Pagetasabbau) which is a picture of their cosmology towards the harmony of life with the natural, social and cultural environment. Based on the results of the study found, it can be concluded that the local wisdom of the Mentawai people plays an important role in mitigating disasters that occur in the Mentawai archipelago district.

Abstract

Family leadership style has an important role in encouraging concrete action regarding household waste management. Parents or heads of households who set a good example and provide active encouragement to family members to participate in environmentally friendly waste management practices can form positive and sustainable habits in the household environment. Thus, it is hoped that this research can make a significant contribution to the role of families in encouraging concrete actions related to household waste management. This research aims to analyze the role of family leadership style in encouraging awareness and action regarding household waste management in a community in Padang City. This research uses a quantitative approach with a causal associative type of research. The sampling method used was a saturated sample, with 63 participants from the local community. The data obtained was described, then a description of the research results was carried out using the TCR technique. The determination analysis technique uses simple linear regression to test the extent of the causal influence between variable (X) on the resulting variable (Y). The research results show that the family leadership style among the community is considered very good, with the respondent's achievement level reaching 90.66%. Meanwhile, awareness and action regarding household waste management is also considered high, with the respondent's achievement level reaching 92.11%. The family leadership style variable was proven to have an influence of 28.4% on community awareness and action regarding household waste management, while the rest was influenced by other factors such as motivation, education level and other environmental factors.

Abstract

One of the main challenges in the reclamation process of former coal mining land is low soil fertility. Common soil characteristics found in former mining land include unbalanced pH, low organic matter content, poor soil structure, and minimal availability of nutrients. This makes it difficult for plants to grow and develop optimally in former mining land areas. This type of research is an experimental research with a Research Design using a Completely Randomized Design (CRD) 4 x 6. The population of this study was all Ruji Bean Plants (Pueraria javanica) growing in the Wire House area of PT. Pacific Coal Mining with a sample of this study of 24 Ruji Bean Plants (Pueraria javanica). The results of this study are that the provision of UFB Organic NPK fertilizer has been proven to help improve soil conditions. The dosage of UFB liquid organic NPK fertilizer solution for optimal Ruji Bean plant growth is in treatment 4 with a dose (90 ml). In terms of economy, the production of UFB liquid organic NPK fertilizer is IDR 40,300/liter, while the price of liquid NPK fertilizer on the market is IDR 100,000/liter. So, the use of UFB liquid organic NPK fertilizer solution can be a good choice for reclamation activities, this can save fertilization costs for post-mining land reclamation activities and is environmentally friendly because UFB liquid organic NPK fertilizer is made from organic materials.

Abstract

The mining industry, especially in the crushing plant area, faces serious problems related to noise that can reach more than 85 dB(A). Noise exposure for 8 working hours is at risk of causing temporary or permanent hearing loss (NIHL), which is a common occupational disease found in crushing plant workers. The type of research used in this study is descriptive analytical with a cross-sectional approach. Data collection techniques were carried out by measuring noise levels in the Crushing Plant area and distributing questionnaires to obtain data on the hearing health of mining workers. The location of this study was at CV. Tekad Jaya. The results of the noise level study at CV. Tekad Jaya showed an alarming situation, where 50% of the 14 measurement points exceeded the threshold of 85 dB, with a peak of 96.86 dB at point Std 10. The health impacts were clearly visible with 46.2% of workers experiencing headaches and 61.5% having difficulty communicating, even though the majority had used PPE. The combination of distance and vegetation has proven effective in reducing noise up to 76 dBA at a distance of 95 meters. The metal plate enclosure system showed positive results, reducing noise levels to 83 dBA inside and 67 dBA outside the building. Recommended control strategies include a zoning system with double protection, worker rotation, and health monitoring for areas >85 dBA, and a preventive approach for zones <85 dBA.

Abstract

Young coconut fibers, often found as waste, contain tannin and anthocyanin compounds that can produce various natural colors, so they can be used as organic dyes. The research method used was an experiment with a focus on testing silk thread dyeing using young coconut fiber extract dissolved in rice field water. This study aims to explore and develop the use of young coconut fibers as a source of environmentally friendly natural dyes. The results showed that young coconut fibers have the potential as organic dyes. Young coconut fiber extract with fermented rice field water solvents produced three color variations depending on the fixator used: brownish black (ferrous sulfate), gray (alum), and brown (lime). Structural tests using Scanning Electron Microscopy (SEM) proved that the dyeing process did not change the cross-sectional shape of the silk thread. In terms of tensile strength, yarn with alum fixation had the highest strength compared to native yarn, ferrous sulfate fixation, and lime fixation. Elongation tests showed the highest elasticity in yarn with alum fixation, followed by lime, ferrous sulfate, and native yarn. The color fastness test against washing at a temperature of 40°C showed a fairly good level of fastness for organic dyes from young coconut fiber
