This research aims to explore the optimization of land clearing techniques in supporting agricultural sustainability in Dahana Tabaloho Village, Gunungsitoli District, North Sumatra. This research involved students of the University of Nias Agrotechnology Study Program who applied land clearing techniques which included weed removal, soil loosening, drainage and bed making. The methods used in this study were direct observation, interviews, and measurement of soil parameters before and after the application of the techniques. The results showed that the combination of traditional and modern techniques in land management can improve tillage efficiency and environmental sustainability. The use of cultivators for soil loosening is proven to speed up the process, but still requires organic fertilizer to maintain the quality of the soil structure. Good drainage is effective in managing excess water and ensuring water availability during the dry season. In addition, making beds with proper direction supports optimal plant growth. The 15% increase in organic matter content and the stability of soil pH to remain neutral are indicators of the success of the applied techniques. Overall, this study provides evidence that proper land management can support sustainable agricultural productivity in the tropics.

This research aims to describe and compare the morphological characteristics of spores in Thallophyta (lichens) and Bryophyta (mosses). The research was conducted at the Biology Laboratory of UIN Sunan Gunung Djati Bandung for one week. This study employed a descriptive method with macroscopic and microscopic observations. Samples of lichens and mosses were analyzed using a light microscope. The results showed that Thallophyta spores have asymmetrical morphology, are pale green, have a count of 15 spores, and are adaptive to extreme conditions. In contrast, Bryophyta spores are round and flat, with a reddish-brown capsule, and a larger number of spores, namely 67. These differences reflect the unique adaptation strategies of the two groups to their respective environments. Lichens, which are a symbiosis between fungi and algae, serve as indicators of environmental quality and grow on various substrates, including polluted areas. Meanwhile, mosses play an important role in maintaining soil moisture, preventing erosion, and supporting water and carbon cycles.

This study analyzes the relationship between social and ecological aspects of agricultural activities in Bonthula Village, Gorontalo Regency. Most of the community relies on maize cultivation as the main commodity, but diversification into perennial crops such as nutmeg, durian, rambutan, cloves, coconut, cocoa, and avocado is also practiced tomaintain soil balance and increase income. The community's ecological awareness is reflected in their understanding of the benefits of perennial crops in improving soil fertility, maintaining moisture, and preventing degradation caused by monoculture maize. The village government supports these practices through perennial crop seed assistance programs aimed at promoting ecosystem sustainability and improving farmers' welfare. This research adopts a descriptive approach with data triangulation from interviews, observations, and document studies. The analysis reveals that the integration of perennial crop diversification and local policy support positively impacts the socio-economic and ecological aspects of Bonthula Village. This community-based agricultural management model can serve as a reference for implementing sustainable practices in other regions facing similar challenges.

Effective agricultural waste management has a huge potential to increase community productivity and income. Agricultural waste, often considered a problem, can be processed into valuable resources such as organic fertilizer, biogas, and animal feed. By utilizing organic fertilizer from agricultural waste, soil fertility can be enhanced and dependence on chemical fertilizers can be reduced, thus contributing to increased crop yields. Biogas produced from the fermentation process of waste can be used as an alternative energy source, which in turn can reduce operational costs and increase income. Moreover, animal feed derived from agricultural waste can improve the quality and quantity of livestock production, which also contributes to changes in the income of livestock farmers. Additionally, good agricultural waste management can reduce environmental pollution and improve public health. Therefore, it is important to raise awareness and knowledge among the community about sustainable agricultural waste management practices. This needs to be complemented by adequate infrastructure and training so that waste can be processed into resources that benefit everyone.    

in facing the changes in culture, thought, and morality that have emerged in the midst of postmodern society. In this context, Mark 4:1-20, which contains the parable of the sower, provides important insights into how the word of God The implementation of a sower for Christians in the postmodern era is a relevant topic to study considering the complex challenges faced by the church and individual Christians are delivered and received in various conditions of the human heart. This study aims to examine the relevance of the teachings in the parable for Christians in the postmodern era. In the postmodern era, where relativism, pluralism, and skepticism towards absolute truth are increasingly growing, the parable of the sower provides an illustration of how the word of God is spread and received in various situations. Just as the sower sows seeds into various types of soil (roadside soil, rocky soil, thorny soil, and fertile soil), so too Christians are faced with varying conditions of heart and mind in receiving the message of the gospel. This study identifies the challenges faced by the church, such as the influence of social media, individualism, and relativism, which can affect the way the word of God is received by postmodern society. Through a theological approach to Mark 4:1-20, this study offers a perspective on how Christians can act as faithful sowers, seeking to sow the seeds of the word with patience, and seeking to respond to various social and cultural conditions that exist wisely. Thus, the implementation of the parable of the sower in the context of the postmodern era not only invites people to actively spread the gospel, but also to understand the various challenges and heart situations that can affect the reception of the word.

This study aims to analyze the influence of soil contour types and depths on soil characteristics using a Randomized Block Design (RBD) method. The research data were obtained from a secondary dataset encompassing physical and chemical soil characteristics across three contour types (Top, Slope, and Depression) and four depth levels (0-10 cm, 10-30 cm, 30-60 cm, and 60-90 cm). The analysis results indicate that soil contour types and depths do not significantly affect most soil characteristics, such as pH, nitrogen content, phosphorus, calcium, sodium, and soil conductivity. However, significant effects were observed on magnesium (Mg) and potassium (K) content. Conversely, area grouping showed significant effects on nearly all tested soil characteristics. These findings highlight the importance of considering geographical variations in soil management to enhance the efficiency and sustainability of agricultural practices. Further research is recommended to explore other factors affecting soil characteristics, such as climate and vegetation types, to support more optimal land management strategies.

The global food crisis has become one of the most pressing issues requiring serious attention, especially as the world's population continues to grow. This growth has led to an increasing demand for food, while agricultural resources such as fertile land, water, and labor become increasingly limited. These conditions present significant challenges for farmers, including droughts that damage crops, floods that devastate agricultural lands, and pest attacks that significantly reduce yields. Furthermore, global climate change exacerbates the situation, directly impacting the stability of food production. Unpredictable weather patterns threaten harvest success, increase the risk of crop failure, and decrease agricultural productivity. Therefore, innovative solutions, such as utilizing Internet of Things (IoT)-based technologies, are urgently needed to support the sustainability of the agricultural sector by enhancing efficiency, effectiveness, and global food security. This study aims to contribute to addressing these challenges through a modern technological approach

Goat urine is liquid waste from goat feces. Goat urine is able to provide macro and micro nutrients and contains growth regulators (ZPT) that plants need. Goat urine contains 1.5% nitrogen, 0.13% phosphorus, and 1.8% potassium. Goat urine contains natural hormones of IAA, gibberellin, and cytokinin higher than other livestock urine. Goat urine processing can be done by fermentation. Fermentation is a process of chemical changes in an organic substrate through enzyme activity produced by microorganisms. The results of fermentation of organic materials such as sugar, alcohol, amino acids, proteins, carbohydrates, vitamins and other organic compounds are easily absorbed directly by plant roots. The use of effective microorganisms in the manufacture of goat urine fermented liquid organic fertilizer aims to accelerate the fermentation process. Effective microorganisms or also known as probiotics are mixed cultures of various types of beneficial microorganisms such as photosynthetic bacteria, lactic acid bacteria, actinomycetes yeasts, fermentation fungi that can improve soil microbes. The use of solid waste of goat manure is commonly done by farmers, but the use of liquid waste (urine) of fermented goats has not been widely known. Therefore, it is important to optimize the use of fermented goat urine as liquid organic fertilizer.

Worm infections are a health concern in Indonesia and all other tropical nations. A number of species, including roundworms (Ascaris lumbricoides), whipworms (Trichuris trichiura), hookworms (Hookworms), Necator americanus, Ancylostoma duodenale, and Strongyloides stercoralis, are members of the Soil Transmitted Helminth nematodes. Children in elementary school are among the age groups most vulnerable to Ascaris lumbricoides. Without a clean and healthy lifestyle, an Ascaris lumbricoides infection might have major repercussions. Research on the correlation between Ascaris lumbricoides infection and total immunoglobulin E levels in primary school students is therefore required. This study uses a cross-sectional, observational analytical design. Children at Lifuleo Village's elementary schools served as the research subjects. The ECLIA method was used to assess total immunoglobulin E levels, and the Kato-Katz method was used to diagnose Ascaris lumbricoides infection under a microscope. An aberrant total immunoglobulin E level of 12.5% was observed in 42.5% of Ascaris lumbricoides eggs, according to the examination results.
