Dependence on chemical fertilizers has caused a decline in soil quality, groundwater contamination, and rising agricultural production costs due to unstable fertilizer prices. In recent years, frequent fertilizer crises have revealed the fragility of reliance on inorganic fertilizers within the national agricultural system. Hence, a transformation toward environmentally friendly and sustainable agriculture is urgently required. This study employed a scoring technique to analyze field observation data, which were narrated based on the written methodology. Respondents’ answers were categorized and classified according to their assumptions or opinions, with scores determined using a Likert scale. The Likert scale measures attitudes, opinions, and perceptions of individuals or groups regarding specific social phenomena. The results showed that key driving factors—such as affordable fertilizer prices, support from agricultural extension workers, and social encouragement from the community—achieved scores above 82%. This finding indicates that external conditions are quite favorable for promoting the use of organic fertilizers. However, major challenges remain, including the limited availability of organic fertilizers in the field and farmers’ long-standing dependency on chemical fertilizers. To address these challenges, it is essential to enhance the market availability of liquid organic fertilizers (POC) through collaboration between producers and farmer groups. Continuous technical assistance should be provided, including demonstration plots that display tangible improvements in rice yields using POC. Furthermore, government support in the form of targeted subsidies or special incentives for farmers transitioning to organic fertilizers is vital, while strengthening the role of farmer groups and agricultural extension workers as catalysts for the adoption of environmentally friendly innovations.

Herbaceous plants play an important role in reducing the negative impact of erosion on the surrounding environment. Their high adaptability and solitary distribution patterns allow herbs to grow in various habitat conditions. One location that shows a fairly high diversity of herbs is in the Jaboi Hot Spring Area, Sukajaya District, Sabang City. This study focused on grouping the types of herbaceous plants in the area and assessing their diversity. Data collection was carried out using a 100-meter line transect method, which was divided into four observation stations. Each station consisted of six 2 x 2-meter square plots used for species inventory. The observation resulted in data on 22 identified herbaceous species, representing 13 families, with a total of 385 individuals. The Convolvulaceae and Fabaceae families were the most dominant groups with four species from each family. The level of species diversity was analyzed using the Shannon-Wiener index, resulting in a score of 2.82, which is classified as moderate. The findings of this study provide preliminary information on the diversity of herbaceous plants in the area, which can be used as a reference for further research and environmental management in the Jaboi Hot Spring Area, Sukajaya District, Sabang City.

This research explores the application of literary formulas in Brandon Sanderson’s novel Mistborn: The Final Empire. The research aims to identify the specific narrative formulas employed within the novel’s structure and to map the pattern by which these formulas are integrated to create its compelling narrative. Using a qualitative approach, the study applies Cawelti’s literary formulas and Vogler’s stages of the journey to analyze key scenes, dialogues, passages, and plot events. Data collection involved close reading and detailed note-taking. The findings show that Mistborn integrates three formulas: adventure, mystery, and romance, into the narrative. By mapping the protagonist’s journey onto Vogler’s twelve stages, the study shows a clear pattern where the adventure formula drives the main plot, the mystery intellectually engages the reader, and the romance provides emotional depth. These findings help explain the narrative appeal of the novel and offer a useful framework for understanding how fantasy stories are structurally composed. The study demonstrates how traditional storytelling formulas can be used to create rich and engaging narratives in modern fantasy literature.

Organic agriculture plays a vital role in Indonesia’s agricultural development, with a key challenge being how to boost productivity efficiently and sustainably. Liquid Organic Fertilizer (LOF) derived from natural materials provides an eco-friendly option to improve soil fertility and crop yields. Bamboo shoots (Bambusa spp.), rich in organic carbon and gibberellin, present strong potential as LOF raw material to support plant growth. This study evaluated the effect of bamboo shoot-based LOF on the growth and yield of white radish (Raphanus sativus). The research was conducted from May to August 2025 in Kalolok, Batupapan Village, Tana Toraja Regency, South Sulawesi, at an altitude of 775 m. LOF was produced by fermenting 200 kg of ground bamboo shoots with 4 kg palm sugar, 1 liter EM4, and 200 liters water for 14 days. Treatments consisted of 0, 100, 200, and 300 ml per liter of water, applied twice at two-week intervals starting 14 days after planting. Using a randomized block design with four treatments and three replications, variables observed included plant height, leaf number, tuber size, and yield. Results showed that 300 ml/liter LOF gave the best outcomes: tallest plants (27 cm), most leaves (15.89), largest tubers (29.37 cm length; 6.06 cm diameter), and highest weight (731 g/plant; 6936.67 g/plot). These effects are linked to balanced nutrients (N, P, K, Mg, Ca) enhancing vegetative growth and tuber development. Thus, bamboo shoot-based LOF at 300 ml/liter is recommended as an effective organic fertilizer for white radish.

The use of organic materials as fertilizers is an important effort to improve soil fertility and crop productivity sustainably. Gliricidia sepium (gamal leaves) is a leguminous plant rich in nutrients such as nitrogen, phosphorus, and potassium, and contains bioactive compounds and microbes that support plant growth. Liquid organic fertilizer (LOF) made from fermented gamal leaves offers advantages including ease of application, high nutrient absorption by plants, and environmental friendliness compared to synthetic chemical fertilizers that may cause pollution and other negative impacts. This study aimed to evaluate the effect of LOF from gamal leaves on the growth and yield of Japanese cucumber (Cucumis sativus L.). The research was conducted at the Experimental Garden of the Faculty of Agriculture, UKI Toraja, South Sulawesi, from April to July 2025. The LOF was produced by fermenting gamal leaves for 15 days using EM-4 solution and palm sugar as activators. The LOF was applied three times at two-week intervals, starting at 7 days after planting (DAP), by soil drenching around the base of the plants. Observed variables included plant height, number of leaves, leaf area, stem diameter, number of fruits per plant and per plot, average fruit diameter and length, and fruit weight per plant and per plot. Data were analyzed using analysis of variance (ANOVA) and the Honestly Significant Difference (HSD) test at a 0.05 significance level. The results showed that application of LOF from gamal leaves at a dose of 300 ml per plant produced the best results across all observed parameters, including plant height, leaf number and area, stem diameter, fruit number, fruit size, and fruit weight per plant and per plot.

Sweet corn (Zea mays L. saccharata) is a high-value horticultural crop whose productivity is closely linked to effective nutrient management, particularly the balanced application of macronutrients—nitrogen (N), phosphorus (P), and potassium (K). This study evaluates the agronomic and economic impacts of applying NPK compound fertilizer at varying doses (0.5×, 0.75×, 1.0×, 1.25×, and 1.5× the recommended rate) on sweet corn growth and yield performance. Field experiments demonstrated that NPK application significantly enhanced vegetative growth parameters, including plant height, leaf number, and stem diameter, with improvements ranging from 15.8% to 37.3% over the unfertilized control. Yield components such as ear length, husked ear weight, and dehusked ear weight also showed marked increases, resulting in higher total yields per plot and per hectare. Among the treatments, the 1.25× dose achieved the highest relative agronomic effectiveness (RAE) at 147%, indicating superior nutrient utilization and biomass conversion. However, the 1.0× dose yielded the most favorable economic outcome, generating a net profit of Rp. 10,780,200 and an R/C ratio of 1.47, suggesting optimal cost-efficiency. These findings underscore the dual benefits of NPK compound fertilizer in sweet corn cultivation, highlighting that precise dosage not only maximizes agronomic performance but also enhances economic viability. The study recommends adopting the 1.0× dose for balanced productivity and profitability, while the 1.25× dose may be considered in contexts prioritizing yield maximization.

This study provides an in-depth examination of the emergence of servitude rights (hak servituut) arising from procedural errors in land parcel division, which result in landlocked plots without road access. Servitude rights, as regulated in Article 674 of the Indonesian Civil Code and reinforced by the Conversion Provision of Article I point 6 of the Basic Agrarian Law (UUPA), constitute a legal burden imposed on one parcel of land for the benefit of another, thereby ensuring that landlocked owners gain reasonable access. Although the UUPA serves as the national agrarian framework, the servitude concept remains highly relevant and functions as a crucial legal instrument to safeguard the rights of affected landowners. This research employs a normative juridical approach, integrating statutory and conceptual analyses to explore the consistency between legal theory and practice. The findings demonstrate that parcel division conducted without considering the social function of land, as mandated by Article 6 of the UUPA, can trigger access disputes that adversely affect community interests. Dispute resolution may proceed through litigation or non-litigation channels, with mediation emerging as the more effective and efficient option for maintaining harmonious relations between parties. Article 667 of the Civil Code provides a clear legal basis for landlocked property owners to obtain access while obligating them to pay fair compensation to the burdened land. Based on these findings, the study recommends strict adherence to lawful land division procedures and the development of detailed technical guidelines on servitude compensation to prevent future disputes and to strengthen legal certainty for all stakeholders.

This study aims to analyze the structure and composition of vegetation on the banks of the Ira River (Wae Ira), Negeri Kamarian, Kairatu District, West Seram Regency. Riparian vegetation plays an important role in maintaining the stability of river ecosystems, both in terms of ecological, hydrological, and biodiversity aspects. The method used in this study is a combination of the continuous strip sampling method and the line plot sampling method, which are applied to four levels of vegetation growth, namely seedlings, saplings, poles, and trees. The results of the analysis show that the vegetation structure in the study area is divided into four strata, with varying species compositions in each stratum. The dominant species found include Pulai (Alstonia scholaris), Pulaka (Cyrtosperma merkusii), Buah rao (Dracontomelon mangiferum), and Salam (Syzygium polyanthum). The highest Importance Value Index (INP) at the tree level is owned by Pulai (Alstonia scholaris) at 54,2. The highest vegetation density is at the seedling level with 52000 individuals/ha and the lowest at the tree level with 341 individuals/ha. The Shannon-Wiener diversity index (H') ranges from 1.87–2.65, indicating a moderate level of diversity. The results of this study indicate that the Ira River border area still has a relatively good vegetation structure and composition, although there are ecological pressures that cause dominance by certain species

The proliferation of fake news across digital platforms has raised critical concerns about information reliability. A notable example is the viral rumour falsely claiming that the Nigerian Minister of the Federal Capital Territory, Nyesom Wike, had collapsed at an event and was rushed to an undisclosed hospital an entirely fabricated claim that caused public confusion. While both traditional machine learning and deep learning approaches have been explored for automated fake news detection, many existing models have been limited to topic-specific datasets and often suffer from overfitting, especially on smaller datasets like ISOT. This study addresses these challenges by proposing a standalone Bidirectional Long Short-Term Memory (BiLSTM) model for fake news classification using the ISOT dataset. Unlike multi-modal frameworks such as the MM-FND model by state-of-the-art model, which achieved 96.3% accuracy, the proposed BiLSTM model achieved superior results with 98.98% accuracy, 98.22% precision, 99.65% recall, and a 98.93% F1-score. The model demonstrated balanced classification across both fake and real news and exhibited strong generalization capabilities. However, training and validation performance plots revealed signs of overfitting after epoch 2, suggesting the need for regularization in future work. This study contributes to the growing body of research on fake news detection by showcasing the efficacy of a focused, sequential deep learning model over more complex architectures, offering a practical, scalable, and robust solution to misinformation detection

This research aims to analyze the crucial role of the shipping agency—specifically PT. Maritime Network Indonesia Dumai Branch—in preparing the vessel departure and arrival schedule (line-up). Line-up preparation is a strategic process that involves vessel plotting at Pelindo Dumai Port and is vital for supporting the smooth running of port operations and loading/unloading activities. The research methodology includes field research (field research) to observe direct practices at the port and literature review (library research) to reinforce the theoretical and regulatory foundations. The findings confirm that the shipping agency plays an important role in ensuring the efficiency of the port schedule. Nevertheless, in practice, the line-up preparation process faces several significant challenges. These obstacles include the limited authority of local agents in independently determining vessel plotting, restricted coordination meeting schedules, and the continued use of manual and inefficient communication methods. This lack of integrated communication often leads to inaccuracies in the initial line-up preparation, forcing agents to recalculate the previously arranged vessel positions. The conclusion of this study suggests the need for developing an integrated system that facilitates real-time communication and reporting to all relevant agencies. Adopting a digital system will enhance process efficiency, ensure proper documentation, and minimize errors, thereby accelerating the vessel plotting coordination process in the field.

Story writing skills are one of the essential competencies in learning Indonesian language at the elementary school level. However, in reality, many students still face difficulties in expressing ideas, organizing plots, and using language appropriately. Therefore, a learning model that can improve students’ story writing skills is needed. Project Based Learning (PjBL) was chosen because it emphasizes student activity, creativity, collaboration, and the production of tangible written works. This study employed a Classroom Action Research (CAR) method based on the Kemmis and McTaggart model, which was carried out in two cycles. The subjects of the study were 14 third-grade students of MI Ziyadatul Iman, Jambi City. The research instruments included a story writing test, student activity observation sheets, and documentation. Data were analyzed using both quantitative techniques (average scores, mastery percentages) and qualitative techniques (student activity and reflection in each cycle). The findings showed that students’ story writing skills improved through the implementation of PjBL. The average score increased from 62.86 in the first cycle to 79.29 in the second cycle. The percentage of learning mastery also rose from 42.86% in the first cycle to 85.71% in the second cycle. In addition, students became more active, creative, and collaborative during the learning process. The implementation of Project Based Learning can therefore enhance the story writing skills of third-grade students at MI Ziyadatul Iman, Jambi City, both in terms of learning outcomes and learning activities.

Tropical forests play an important role as carbon sinks and biomass stores, including through the litter produced by vegetation. Litter contributes to nutrient cycling, maintains soil fertility, and is an important component of ecosystem carbon reserves. This study aims to estimate the biomass and carbon content of litter in the Jaboi Hot Spring Flow Area, Sukajaya District, Sabang City. The study was conducted in June 2025 using a 100 m long line transect method with four transects, each consisting of 18 1 x 1 m plots. Leaf litter samples were collected, their wet weight was measured, dried in an oven for 48 hours, and their carbon content was calculated based on the percentage of organic carbon of 0.47. The results showed a total litter biomass of 8,106 kg/m² with an average of 2,027 kg/m², and a total litter carbon of 3,809 kg/m² with an average of 0,952 kg/m². The highest values were found at Station 3 (2,354 kg/m² and 1,106 kg/m²) and the lowest at Station 1 (1,691 kg/m² and 0,795 kg/m²). Variations in values are influenced by soil physical-chemical factors, vegetation density, and climatic conditions, which influence production and decomposition rates. These results emphasize the importance of monitoring biomass and litter carbon to support forest management and conservation.

Shrub vegetation is an important component in the structure of vegetation communities that have a significant ecological role, especially in maintaining soil stability and supporting biodiversity. One area that has the potential for shrub vegetation diversity but has not been scientifically documented is the Jaboi hot spring area, Weh Island, Sukajaya District, Sabang City. The purpose of this study was to investigate various types of shrub vegetation found in the study area and to calculate the diversity index. Data collection was carried out using a one-hundred-meter line transect method divided into four paths, with one pair of transects directed towards residential areas and plantation areas, while the remaining two transects were directed towards areas that were still forested. At each transect there were six observation points with a distance between points of 20 meters, each point consisting of three quadrat plots measuring 2 × 2 meters. Analysis of the diversity index used the Shannon-Wiener formula (H’). The results showed that there were 9 shrub species from 7 families with a total of 169 individuals from four observation stations. The Melastomataceae family dominates the shrub community with two main species, Melastoma malabathricum and Memecylon caeruleum. The diversity index value is 2.17, which is included in the moderate category (H = 2–3). This diversity is influenced by the physical-chemical conditions of the environment, such as acidic soil pH (4.4–5.5) and relatively stable temperatures, although temperatures exceeding the optimum limit were found in some locations. This study provides initial data on the potential of shrub vegetation as a basis for ecosystem management and conservation in the area.

One example of a case of falsified documents in the issuance of overlapping land certificates occurred in East Luwu Regency and was raised in court through Decision Number 90/Pid.B/2020/PN MII. In this case, it was discovered that land certificate falsification was carried out by a land mafia, resulting in the emergence of two certificates for the same plot of land. This practice not only harms the legitimate owner but also creates laws and gives rise to complex agrarian conflicts. This research uses a normative juridical method, with an approach based on laws and court decisions. The results show that the preservation was an intentional act carried out by one party, with the aim of controlling land rights that did not belong to him. In the decision, the perpetrator was found guilty and sentenced because it was also proven to have falsified documents, as stipulated in Article 263 of the Criminal Code (KUHP). From this case, it can be concluded that law enforcement against overlapping duplicate certificates is very important to ensure legal certainty and protection. Protection efforts for land rights holders are carried out through a land registration process that complies with procedures based on Law Number 5 of 1960 concerning the Principles of Agrarian Law. Compliance with these procedures can provide a strong basis for identifying legitimate rights holders and preventing future damage, including cases of overlapping certificates caused by document falsification. To prevent the recurrence of similar cases, it is necessary to improve the monitoring system and digitize land data comprehensively by the National Land Agency (BPN). An integrated digital-based land system can minimize the opportunity for the issuance of duplicate certificates for a single plot of land, because all land rights data can be accessed and disclosed transparently and in real time.

The author constructs the story world through elements such as plot, character, and setting. These elements are interconnected and form a cohesive whole within the narrative. This study aims to examine and analyze the story elements in the novel Angin Bersyair by Andrei Aksana. The theoretical framework used in this research is Robert Stanton's structuralism theory. This research employs a descriptive qualitative approach. Data collection was carried out through literature study, using techniques such as reading the novel, highlighting and identifying data, classifying, selecting, compiling the data corpus, and organizing the data. The results of the analysis show that the novel Angin Bersyair by Andrei Aksana is constructed using a mixed plot structure, the setting is categorized into place, time, and atmosphere. The characterization includes both main and supporting characters. The mixed plot in the novel combines both progressive and regressive plot patterns, allowing the author to weave past and present events fluidly to enrich the narrative tension and emotional depth. The temporal shifts also reflect the psychological complexity of the main characters, especially in relation to themes of love, identity, and longing. The setting of place varies from urban environments that reflect modern social dynamics to more introspective or symbolic places that reveal the characters’ inner worlds. The time setting spans multiple periods, indicating a narrative that draws heavily on memory and personal transformation. The atmosphere often shifts between melancholic, romantic, and contemplative tones, aligning with the protagonist’s emotional journey. Character analysis reveals a strong central figure whose emotional struggles and internal conflicts are supported and contrasted by secondary characters, enriching the story’s multidimensionality. The protagonist is depicted with psychological depth, while the supporting characters serve as foils or catalysts for change. Overall, this research highlights how Angin Bersyair employs literary elements to construct a rich and emotionally engaging narrative grounded in structuralist principles.
