Emosi Tokoh Utama dalam Novel Sheiland Karya Bayu Permana dan Korelasinya dalam Pembelajaran Sosial Emosional

Piska Piska — 2026-01-01

This study aims to: 1) describe the form of emotions of the main character reflected through id in the novel Sheiland by Bayu Permana; 2) describe the emotional form of the main character reflected through the ego in the novel Sheiland by Bayu Permana; 3) describe the form of the main character's emotions reflected through the superego in the novel Sheiland by Bayu Permana; and 4) describe the correlation between the emotional forms of the characters contained in the novel Sheiland by Bayu Permana and social-emotional learning. This research is a qualitative descriptive research using Freud's theory of personality structure, namely id, ego, and superego. Research data in the form of citations in the form of sentences or paragraphs. The source of the data comes from the novel Sheiland by Bayu Permana. The data collection technique is carried out by reading and recording techniques. Data analysis uses the Miles & Huberman model which includes data collection, data reduction, and conclusion drawn. The results of the study show that the various forms of emotions of the main characters reflected through the dynamics of id, ego, and superego show complex patterns of emotion management. Although each personality structure displays a different variety of emotions, there is generally a shift from spontaneous emotional impulses to more mature moral control and judgment. The correlation between the main character's emotional dynamics and social-emotional learning is seen through the way the main character expresses, understands, and manages his emotions in various situations. These emotional experiences reflect the process of developing self-awareness, social awareness, self-management, relational skills, and responsible decision-making. This research provides a scientific contribution by presenting a new perspective on the integration of literary psychoanalysis studies and social-emotional learning, thus opening up opportunities for the use of literary work analysis as a medium to strengthen students' social-emotional competence.

Sistem Pertanian Terpadu di Lahan Kering : Integrasi Sapi-Jagung-Gamal di Das Batu Lanteh, Sumbawa

Sudarli Sudarli — 2026-01-04

The Integrated Agricultural System (SPT) is a strategic approach in dryland development, as it is able to respond to various biophysical constraints such as water limitations, low soil fertility, and production fluctuations. In the Batu Lanteh watershed, Sumbawa Regency, the integration of cattle-corn-gamal is a synergistic model that combines the production of food crops, the provision of forage feed, and the use of livestock waste as a source of organic fertilizer. Various studies show that plant-livestock-tree integration can increase corn productivity, improve soil quality, increase land use efficiency, and strengthen the economic resilience of farmer households (Irawan et al., 2024; Panjaitan et al., 2019). This study analyzes the integration system from an epistemological perspective, especially in looking at the relationship between farmers' local knowledge and scientific knowledge developed through research and program interventions. The results of the review show that there is an epistemological tension between local knowledge that is empirical-contextual and scientific knowledge that is procedural-generalizing. However, the integration of the two is possible through a hybrid epistemology that emphasizes co-creation of knowledge, dual validation, and farmer participation in the innovation process. The conclusion of the study emphasizes that the success of cattle-corn-gamal integration is largely determined by the harmonization between local and scientific perspectives, so that this epistemological approach becomes the basis for the formulation of a more adaptive, participatory, and sustainable dryland agricultural policy in Sumbawa Regency.

Representasi Sistem Nilai dan Perilaku Budaya dalam Tradisi Nganak-Merariq Masyarakat Sasak : Kajian Linguistik Antropologi

Muhamad Wahyu Ramdani — 2026-01-04

This study aims to reveal the role of language in representing the cultural values and social structure of the Sasak community through an analysis of the lingual forms used in the merariq tradition. Based on an anthropological linguistic approach, this study uses a qualitative method with observation techniques, in-depth interviews, and documentation of merariq ritual practices in several Sasak communities in Lombok, West Nusa Tenggara. Data were analyzed using the intralingual matching method with the link-comparison technique to find the relationship between language structure and cultural meaning. The results of the study identified 41 lingual forms classified into six main domains, namely: mbait, beselabar, bekawin, berejap, begawe, and rebaq jengkis. Each domain depicts the stages of the traditional procession that represent the values of courage, sacredness, solidarity, honor, and social integration. Language in the merariq tradition functions not only as a means of communication, but also as a symbolic medium that strengthens the value system, social legitimacy, and cultural identity of the Sasak people. These findings reinforce the theory of Mahsun (2024), Duranti (1997), and Geertz (1973) that language is a cultural practice that shapes collective social consciousness. Theoretically, this research contributes to the development of the study of anthropological linguistics in Indonesia, while practically supporting efforts to preserve ritual languages and local oral traditions. Further research is suggested to explore dialectic variation and cross-cultural comparisons to broaden understanding of the relationship between language, culture, and identity.

Analisis Lem Kuku Cair dan Gel Dilihat dari Bentuk dan Ukurannya

Esta Ramadhani Windyastari — 2026-01-05

This study was conducted to analyze the results of the differences between liquid nail glue and gel nail glue based on the effectiveness of their use. The method used was direct observation by conducting experiments on several commercial products, accompanied by simple testing on the ease of application, adhesion, and durability of the results of use in four female participants. The results showed that although liquid nail glue has a smaller packaging and a thinner texture making it easy to apply, its adhesion tends to be lower and less durable. In contrast, gel nail glue that is generally packaged in larger containers with a thicker consistency has been shown to provide stronger adhesion as well as higher resistance to the nails. This study aims to analyze the difference between liquid nail glue and gel nail glue in its application to gel press-on nails, by reviewing the packaging shape, product size, and adhesion effectiveness. This research is simple experimental/comparative. Observations were made through direct application tests using several types of press-on nails. The results show that liquid glue, although easy to apply, tends to be less stable on the surface of the press-on gel and comes off more quickly. In contrast, gel nail glue with its thick texture provides stronger adhesion and is able to maintain press-on nails longer, even at intensive daily activities. Therefore, gel glue is considered much more effective and is recommended as the main choice for gel press-on nail installation.

Metafora Perempuan Sasak dalam Novel Jatiswara Karya Lalu Agus Fathurrahman

Marlina Marlina — 2026-01-10

Literary works not only function as aesthetic expressions, but also as a reflection of culture and social value-forming media, including representing women. Jatiswara's novel was chosen as the object of study, because it displays the symbolism of women that is full of meaning and firmly rooted in the context of Sasak culture. The purpose of this research is to describe the forms of women's metaphors and uncover the representation of Sasak women's feminism in the text of the novel. The research uses a qualitative method with the conceptual metaphor approach of Lakoff and Johnson and the concept of true women and new women feminism. The results of the study show that the metaphor of women in this novel is classified into three main categories of women's metaphors, namely structural, ontological, and orientational. The representation of Sasak women's feminism shows ambivalence, namely women present as noble true women and moral guardians, as well as new women who are critical, independent, and progressive. This research contributes to the development of the study of conceptual metaphors and local feminism in Indonesian literature.

Amrullah Amrullah — 2026-01-11

The integration of livestock-food crops and horticulture is a strategic approach in realizing a sustainable agricultural system, especially in irrigated areas such as the Batu Bulan irrigation in Sumbawa Regency. This system not only increases resource efficiency through the utilization of crop waste as animal feed, the use of organic fertilizer from feces, and the planting of legumes to improve soil fertility, but also has the potential to be developed into agro-edutourism that can increase farmers' income. This study aims to analyze the potential of integration from the perspective of ontology, epistemology, and axiology, and assess its relevance as a basis for developing sustainable agro-edutourism. The method used is a systematic narrative review of international literature (2015-2024) covering the themes of agriculture-livestock integration, agro-edutourism, sustainability, and the philosophy of science. The results of the study indicate that livestock-crop integration has an ontological basis as an integrated agroecological system, an epistemological basis through scientific and local knowledge, and an axiological basis as a source of economic, educational, and ecological value. The development of integrated agro-educational tourism in the Batu Bulan irrigation system has the potential to increase farmer incomes, improve soil health, and strengthen local food security. With institutional support, technology, and multi-stakeholder collaboration, this model can become a viable and valuable strategy for sustainable agricultural development.

Gagal Mengikat Tinggi-Heron-Relasi Sisi : Analisis Miskonsepsi Mahasiswa pada Segitiga

Lutfiyah Lutfiyah — 2026-01-12

This study aims to identify and describe in depth the emergence of conceptual misconceptions and procedural errors, as well as the dynamics of students' thinking processes when solving triangle geometry problems. The research used a descriptive qualitative approach with a case study design on three mathematics education students who had taken basic geometry, selected purposively to represent a variety of academic abilities and allow for intensive exploration of thought processes. The instrument is a triangular geometry problem solving task that looks for height, area, and lateral relations. Data was collected through written answer sheets, video recordings of the work, and retrospective clarification interviews, then analyzed qualitatively to trace patterns of misconceptions and procedural errors in the problem-solving flow. Data validity through source triangulation and trail auditing. The results showed that the three students displayed a neat calculation procedure, but were conceptually fragile. The height of a triangle is not interpreted as a perpendicular relation, the use of the theorem is carried out without prerequisites, and the relations between the lateral segments are assumed intuitively. Weak monitoring and evaluation during the problem-solving process hinders the formation of a coherent conceptual framework. These findings confirm the need for geometry learning that emphasizes the status of mathematical objects, adherence to the prerequisites of concepts and theorems, and the development of reflective monitoring habits in problem solving.

Dampak Perubahan Iklim Global terhadap Keanekaragaman Hayati dan Stabilitas Ekosistem Alam : Review

I Wayan Karmana — 2026-01-13

Global climate change has become one of the main drivers of the biodiversity crisis and the instability of natural ecosystems in various parts of the world. This study aims to systematically synthesize scientific findings related to the impact of climate change on biodiversity and ecosystem stability through a Systematic Literature Review (SLR) approach. The study was conducted on national and internationally reputable scientific articles published in the period 2010-2025, with an emphasis on the last five years. Literature searches were conducted through Google Scholar, Scopus, Web of Science, and PubMed databases using keywords related to climate change, biodiversity, and ecosystem stability. Study selection followed the PRISMA guidelines with strict inclusion and exclusion criteria to ensure the quality and relevance of the literature. The results of the synthesis indicate that climate change has a significant impact on biodiversity through shifts in species distribution, phenological disruption, habitat degradation, and increased extinction risks, especially for tropical and endemic species. This decline in biodiversity directly contributes to the weakening of ecosystem stability and resilience, both in terrestrial, freshwater, and marine ecosystems. The loss of keystone species and reduced functional redundancy have been shown to reduce the ability of ecosystems to maintain essential ecosystem functions and services, such as nutrient cycling, primary productivity, coastal protection, and climate regulation. This study confirms that biodiversity is a key foundation for ecosystem stability and that conservation efforts need to be closely integrated with climate change mitigation and adaptation strategies through an ecosystem-based approach.

Effect of Soil Moisture on Vibration Detection Using an ESP32-Based IoT System

Kisman Akuba — 2026-01-14

Earthquakes are natural disasters that frequently occur due to inadequate soil structure and varying soil moisture conditions, which significantly influence ground vibration characteristics. This study aims to investigate the effect of soil moisture conditions, specifically dry and wet soil on vibration response. The system employs an SW-420 vibration sensor integrated with an ESP32 microcontroller for data acquisition and real-time monitoring. The experiment was conducted on a small-scale soil medium, with vibration data recorded at one-second intervals for a duration of 60 seconds. The measured vibration signals were transmitted and monitored in real time, then analyzed to determine which soil condition exhibits greater vibration damping characteristics. The results indicate that soil moisture has a significant effect on the vibration sensor response. The highest average ADC value was obtained in dry soil at 823.21, while wet soil produced a lower average ADC value of 533.16. The decrease in ADC values demonstrates increased vibration damping as soil water content increases. These findings confirm that higher soil moisture enhances energy absorption and reduces vibration transmission. Therefore, the IoT-based vibration detection system using the ESP32 and SW-420 sensor is capable of distinguishing soil vibration characteristics under different moisture conditions and shows strong potential for further development as an early warning system for landslide mitigation.

Bahasa sebagai Medium Makna : Tinjauan Filsafat Bahasa terhadap Hakikat Bahasa Manusia

Novitasari Novitasari — 2026-01-15

Language is a fundamental phenomenon in human life that plays a role not only as a means of communication, but also as a medium for the formation of meaning, thoughts, and social reality. This study aims to analyze the nature of language as a medium of meaning in the perspective of the philosophy of language through the thoughts of the main figures, namely Ferdinand de Saussure, Gottlob Frege, Ludwig Wittgenstein, and J. L. Austin and John Searle. This research uses a qualitative approach with a literature review method, with data sources in the form of classical and contemporary works on the philosophy of language and relevant scientific literature. The analysis is carried out in a descriptive-analytical and reflective-critical manner to uncover the main concepts of language and meaning. The results of the study show that language has a constitutive role in human life. Saussure asserts that meaning is both structural and conventional; Frege shows the cognitive dimension of meaning through the distinction between sense and reference; Wittgenstein views meaning as a use in the context of social practice; while Austin and Searle emphasize the performative power of language as a social action. Thus, language not only represents reality, but also shapes the way humans think, understand, and construct social reality. This study makes a theoretical contribution to the development of the philosophy of language and its relevance in the study of linguistics, education, and the humanities.

Sintesis dan Karakterisasi Nanokomposit Fe3O4/PANI sebagai Komponen Anoda Baterai

Balkis Br Harahap — 2026-01-23

Magnetic materials such as Fe₃O₄ have high potential as conductive materials and energy stores. However, its limited electrical properties require modification through the addition of conductive polymers to improve its performance. The combination of Fe₃O₄ and Polyanillin (PANI) is expected to improve conductivity and capacitance through the formation of Fe₃O₄/PANI nanocomposites. In this study, Fe₃O₄/PANI nanocomposites were synthesized using a co-precipitation method with local iron sand-based materials, then combined through an in situ polymerization method using aniline monomer volume variations of 4 mL, 6 mL, 8 mL, and 10 mL, coded PA1, PA2, PA3, and PA4, respectively. The results of characterization using X-Ray Diffraction (XRD) showed the formation of two main phases, namely magnetite (Fe₃O₄) and maghemite (γ-Fe₂O₃). Scanning Electron Microscopy (SEM) analysis showed that increased volume of aniline monomer resulted in a more homogeneous composite surface, although excessive volume led to overpolymerization. The test results using the LCR Meter showed an increase in capacitance and electrical conductivity values to reach optimal conditions in the PA3 sample, with a crystal size of 50.94 nm, capacitance of 8.9 F, resistance of 1.0 Ω, and conductivity of 127.4 S/m. These results prove that the variation in aniline monomer volume has a significant effect on the structural and electrical properties of Fe₃O₄/PANI nanocomposites. The optimum composition of PA3 shows high potential as an anode material or conductive energy storage electrode that supports the development of environmentally friendly and sustainable energy technology.
