This study aims to examine the gastronomy of the traditional culinary dish Ayam Napinadar as part of Batak cultural identity, covering aspects of history, ingredients, processing techniques, cultural values, and preservation challenges. The background of this research is based on the importance of maintaining the sustainability of traditional cuisine amid modernization and changes in consumption patterns. The method used is a qualitative approach through in-depth interviews with three informants, namely an MSME (Micro, Small, and Medium Eterprises) practitioner, a traditional leader, and a consumer. The results show that Ayam Napinadar has a unique characteristic in the use of andaliman and blood (gota) as its distinctive flavor. Traditionally, the cooking process involves grilling over firewood to produce a characteristic smoky aroma, although it has now shifted to more practical methods without altering the original recipe. From a cultural perspective, Ayam Napinadar holds symbolic meaning as an expression of prayers, blessings, and joy in various Batak traditional ceremonies. However, there are challenges in its preservation, such as the declining participation of younger generations in traditional activities and the increasing influence of modern foods. In conclusion, Ayam Napinadar functions not only as food but also as a medium for preserving cultural values and ethnic identity. This study provides benefits as a basis for developing gastronomic tourism and strategies for preserving traditional cuisine through education, collaboration, and the use of modern promotional media.

This study examines the export barriers encountered by emerging small and medium-sized enterprises (SMEs) in Indonesia, with a focus on export documentation challenges, tariff constraints, and the adaptive marketing strategies employed to sustain international market engagement. Employing a qualitative case study approach, this research investigates PT Albarka International Group, a nascent export-import company established in 2021 and headquartered in Malang, East Java, which specializes in the export of natural commodities including Bakhur-related materials (opercula shells, damar resin, agarwood), spices, and other Indonesian products to Middle East markets including Yemen, Saudi Arabia, UAE, Libya, Sudan, and Djibouti. Data were collected through in-depth interviews with key company personnel and supplemented by document analysis. Findings reveal three primary export barriers: (1) high shipping tariffs relative to regional competitors, frequently triggering order cancellations by importers; (2) complex and time-intensive export documentation requirements, particularly for regulated natural resource products subject to CITES compliance, fish quarantine certification (Health Certificate), and customs declaration (PEB); and (3) internal organizational constraints stemming from overlapping job roles. In response, PT Albarka has adopted adaptive strategies including Full Container Load (FCL) consolidation to reduce per-unit shipping costs, advance payment systems (TT in advance) to mitigate importer default risk, and collaborative consultation with customs and quarantine authorities. The study contributes to the SME internationalization literature by demonstrating how resource-constrained emerging exporters navigate institutional and logistical complexities in developing economy contexts, offering practical insights for SME practitioners and export policy stakeholders.

Seren Village has abundant organic waste potential, particularly banana peel waste generated from banana-processing MSME activities and wood ash resulting from household firewood combustion. To date, this waste has not been optimally utilized and is often discarded, thereby posing potential environmental problems. This study aims to process banana peel waste and wood ash into an innovative, environmentally friendly shoe polish made from natural materials, while also enhancing the economic value and welfare of the community. The research employed a descriptive qualitative method with a case study approach. Data were collected through observation, interviews, and documentation involving the women’s Family Welfare Empowerment Group (PKK) of Seren Village as the target participants. The shoe polish production process includes drying and grinding banana peels, mixing them with a wood ash solution that functions as a natural coloring agent, adding supporting materials, and heating the mixture until a ready-to-use shoe polish is obtained. The results indicate that the shoe polish produced from banana peels and wood ash has a solid texture, is slightly coarse, non-glossy, and has a relatively fast drying time of approximately one minute. In addition, the product shows good resistance to water splashes and does not damage the surface of shoes. The use of natural ingredients makes this shoe polish safer for health. The utilization of this waste has the potential to support MSME development, reduce environmental pollution, and sustainably improve the welfare of the Seren Village community.

Compare the growth of F2 white oyster mushroom seedlings between corn cobs and a mixture of corn cobs and wood powder. 3). Improve the skills and add to the experience and knowledge of students so that they can apply the knowledge they have gained in the lecture hall. This study used a comparative descriptive experimental approach, which is to compare the growth of F2 white oyster mushroom (Pleurotus ostreatus) seedlings on two different types of seedling media. This research was conducted at the Wairita Farm in Wairbleler Village, Waigete District, Sikka Regency, East Nusa Tenggara Province, over a period of 7 days (Monday to Sunday) during working hours from 08:00 to 16:30 with a break from 11:30 to 14:00. This location was chosen because it is an agricultural business unit engaged in the cultivation of white oyster mushrooms (Pleurotus ostreatus). The study period was 3 months, from September 17 to November 17, 2025. Independent variables and dependent variables. Data were obtained through direct observation of mycelium growth, daily recording during the incubation period, and visual documentation. The results of this study indicate that the success of white oyster mushroom F2 seedling propagation is greatly influenced by the suitability of the medium to the physiological and ecological characteristics of the mushroom. A mixture of corn bran and wood powder proved to be more suitable and is recommended for use in the propagation of F2 white oyster mushroom seeds compared to pure corn bran media.

This study investigates biomass-derived surface engineering of AISI 1020 steel for electromedical applications using galam wood charcoal and chicken bone waste as carburizing media. Surface modification is required to improve the mechanical performance of low-carbon steel, particularly in applications that demand high wear resistance and long-term durability. A pack carburizing approach was applied using various ratios of biomass-derived media at a treatment temperature of 800 °C for 2 hours. Chemical composition was analyzed using Optical Emission Spectroscopy (OES), surface hardness was evaluated using Micro Vickers hardness testing, and microstructural characteristics were observed using optical microscopy. The results show a significant increase in surface carbon content with increasing fractions of chicken bone powder, indicating its effectiveness as a carbon donor and diffusion promoter. The surface hardness increased from approximately 150 HV in the untreated condition to a maximum of about 860 HV in the treated specimen. Microstructural observations revealed the formation of a distinct carburized layer with increasing thickness and uniformity, consistent with enhanced carbon diffusion and surface strengthening. These findings demonstrate that biomass-derived surface engineering provides an effective and sustainable approach for improving the surface properties of low-carbon steel. The proposed method offers strong potential for environmentally friendly manufacturing of durable and reliable electromedical components.

This study aims to analyze product failures and propose improvement actions for cabinet products at CV. Arafah Jaya Purwakarta. Based on production data from November 2024 to April 2025, cabinet products showed the highest defect rate compared to other products, reaching 13%. The most common defects include wood cracks, warped wood, and brittle wood. Failure Mode and Effect Analysis (FMEA) was applied to identify and prioritize potential failures based on the Risk Priority Number (RPN), while Fault Tree Analysis (FTA) was used to systematically determine the root causes of failures. The analysis results indicate that the main causes of defects are related to substandard raw material quality, environmental conditions, and insufficient supervision during the production process. Based on the results of FMEA and FTA, improvement proposals were developed using the 5W+1H approach, focusing on improving raw material selection, controlling wood storage conditions, and enhancing work procedures and production supervision. These improvement efforts are expected to reduce defect rates and improve the overall quality of cabinet products.

Wood consumption in Indonesia, which is expected to reach more than 64.84 million m³ by 2025, is putting enormous pressure on forests, as evidenced by the reduction in forest area through the clearing of 96,230 hectares of forest in 2023. To reduce dependence on wood as a building material, alternative materials with comparable physical and mechanical properties are needed. Bamboo, especially laminated bamboo, was chosen because it has high tensile strength, a short harvest time, and abundant availability. This study examines the behavior of hollow section laminated bamboo beam-column connections with a glue-in-rod-bracket system to determine the ductility of the connection under unidirectional (static) loads. An experimental method was used with the independent variables of diameter and number of bolts, while the dependent variables included the moment-rotation of the connection, stiffness, strength, and ductility. The results show that the average ductility values for 4 and 6 thread rods D6, D8, and D10 mostly meet the SNI 1729 (≥1.25) and AISC 360 (rotation >0.03 rad) standards, with classifications ranging from "partially ductile" to "fully elastic." However, the 10-diameter 6-thread rod only achieved a ductility of 1.2, thus failing to meet the SNI standard. Based on the Handbook of Structural Steel Connection Design and Details, all connections fall into the non-seismic category because their ductility values are less than 3. These findings confirm the potential of laminated bamboo as an environmentally friendly construction material, while also providing technical guidelines for the design of non-seismic beam-column connections.

The unknown exact flexural strength of low carbon steel, Randu ribs wood, paving stones, and lightweight bricks is a problem faced. The purpose of this research is to obtain the flexural strength of low carbon steel, Randu ribs, paving stones, and lightweight bricks. The research method is carried out through the preparation of low carbon steel specimens 16mmx200mm, Randu ribs 40mmx60mmx250mm, paving stones 55mmx100mmx200mm, lightweight bricks 95mmx100mmx300mm, Tarno Grocky flexural testing machine settings, flexural testing support distance for low carbon steel 160mm, Randu ribs 220mm, paving stones 170mm, and lightweight bricks 260mm, flexural testing of each material, making flexural stress and deflection curves for low carbon steel, and analyzing flexural test results. The results of the study showed that the flexural strength of low carbon steel was 698 MPa at a deflection of 1.1 mm, the flexural strength of Randu rib wood in an upright position was 40.7 MPa, in a horizontal position was 55.5 MPa, in a normal position of paving stone in an upper position (normal) was 6.64 MPa, in a lower position (upside down) was 6.62 MPa, and in a lightweight brick was 1.28 MPa, which implies that the type of material, the distance between supports and the cross-section of the specimen greatly affect its flexural strength, except for ductile materials for low carbon steel which do not have flexural strength, but have yield strength at a certain deflection.

Technological developments and modern lifestyles have indirectly changed the way elementary school children interact with their surroundings. Most of them spend all day playing with gadgets. The lack of physical interaction with the natural environment is not just a matter of preference, but can also affect many important aspects of child development. Therefore, an innovative approach is needed to bridge this gap, namely, through aquascape training. Aquascape is the art of arranging and combining aquatic plants, water, sand, stones, driftwood, and other elements in a playful manner through a combination of underwater aesthetic styles in an aquarium. The purpose of this training is for children to be invited to directly recognize and understand aquatic ecosystems, but also to actively practice their responsibility, creativity, and awareness. Thus, it is hoped that aquascape training can divert a small portion of screen time to more meaningful real experiences, shaping a generation that is more connected to nature and the surrounding environment. The community service program was conducted for 110 fifth-grade students at Kebalenan State Elementary School in Banyuwangi Regency on January 14, 2025. The activity was carried out in person. Session 1 focused on Environmental Education and Ornamental Fish, while Session 2 involved training in creating a simple aquascape. During the training, the students showed high motivation, enthusiasm, and interest in participating in the activity.

Islamic architecture in the archipelago cannot be understood as simply a transfer of physical forms from the Middle East to Southeast Asia. It is the result of a deep cultural dialogue between universal Islamic principles and local wisdom that has been formed since pre-Islamic times. When Islam spread in the archipelago, it did not exist as a force that negates Hindu, Buddhist, and vernacular traditions, but rather proceeded through visual and structural synthesis that gave birth to a distinctive and hybrid Islamic architectural identity. One of the most iconic manifestations of this process is the use of overlapping roofs in historic mosques such as the Great Mosque of Demak and the Great Mosque of Banten. Different from typical Persian or Mediterranean stone domes, this multi-storey wooden structure is inspired by the concept of Meru in Hindu-Javanese architecture. The choice is not only symbolic, but also a functional adaptation to the tropical climate, as it allows for efficient rainwater disposal as well as optimal natural ventilation. Spatially, the placement of mosques follows the concept of Catur Gatra Tunggal, which is the integration of mosques with squares, government centers, and markets. This pattern reflects the integration between the spiritual, political, and economic life of the community. In the interior, the use of Saka Guru shows the appointment of local construction techniques as the main element of worship buildings. Aspects of syncretism are also seen in ornamentation, where pre-Islamic figurative motifs are transformed into flora and calligraphy patterns that are in harmony with the principles of Islamic aniconism. Thus, the archipelago's Islamic architecture represents Islam as an inclusive and contextual force that is able to process local traditions into a sustainable new identity.

This study aims to understand how green accounting practices are constructed as a social reality within organizations and how environmental awareness develops through social interaction, organizational values, and culture. The research adopts an interpretive qualitative approach within the social construction paradigm (Berger & Luckmann, 1966). Data were collected through in-depth interviews, participant observation, and document analysis in organizations that have implemented sustainability reporting. The analysis employed an interpretive thematic approach to uncover the meanings underlying environmental accounting practices. The findings indicate that green accounting functions not only as a technical reporting instrument but also as a mechanism for shaping organizational moral and ecological awareness. Environmental awareness is constructed through three main stages: the externalization of sustainability values by leadership, objectivation through policies and reporting systems, and internalization within work behavior and organizational culture. Participatory, reflective, and innovation-oriented organizational cultures strengthen the substantive implementation of green accounting, whereas bureaucratic structures tend to produce symbolic practices or greenwashing. Theoretically, this study reinforces the view that accounting is a social practice that both shapes and is shaped by collective consciousness (Hopwood, 1992; Gray, 2010). Practically, the findings highlight the importance of visionary leadership and social learning spaces in fostering a sustainability-oriented organizational culture. Thus, green accounting is understood as a social process that plays a strategic role in realizing ethical, sustainable, and environmentally responsible organizations.

This study discusses the design and development of an automatic safety system for a wood cutting machine using Arduino Uno, a PIR (Passive Infrared) sensor, and a servo motor as the main components. The system is designed to automatically stop the movement of the wood cutting machine when human motion is detected around the cutting area, thereby minimizing the risk of work-related accidents. The research method includes hardware design, microcontroller programming, and system response testing using two types of test objects: the human body and a wooden block. The results show that the system operates according to the programmed logic. When the PIR sensor detects human motion, the servo motor stops and the red LED lights up as a danger indicator. In contrast, when no human motion is detected, the servo motor continues to move normally and the green LED remains on as a safe indicator. The system’s average response time is 0.6 seconds, indicating a fast and accurate performance. Therefore, the designed system is considered effective and can serve as a prototype of a simple safety tool to enhance operator safety in wood cutting machines.

This research is based on the awareness that music functions both as an artistic expression and as a cosmological representation embedded within the cultural structures of traditional societies. The Siwaluh Jabu traditional house in Lingga Village, North Sumatra, was selected as the object of study to examine the relationship between music and the cosmological views of the Karo people. The purpose of this study is to reveal the meaning of music within cultural practices and rituals carried out in the Siwaluh Jabu House, as well as to explore musical elements that reflect the continuity between humans, ancestors, and the universe. This research employs a qualitative approach, with data collected through literature review, participatory observation, and interviews with traditional leaders and local artists. The data analysis was conducted through data reduction, classification, data presentation, and drawing of conclusion. The results of the study show that music both the vocal mantra “ole…ah…ole” and the Gendang Lima Sendalanen ensemble contains symbolic values that interpret wood as a natural element, sustain social connections between groups, and reinforce the social system embedded in the spatial organization of the Siwaluh Jabu traditional house. Music serves as a medium of spiritual and cultural communication that unites the physical and metaphysical dimensions of life. The implications of this research enrich the perspective of music culture and emphasize the importance of preserving traditional music as a local knowledge system integrated with the cosmology of the Karo people.

The use of sengon albasia ash waste as a partial cement substitute in concrete production is carried out to reduce combustion waste and also reduce cement use. This study focuses on the use of sengon albasia wood ash waste. The use of sengon albasia wood ash as a cement substitute causes a significant decrease in the slump test value. The use of sengon albasia wood ash as a partial cement substitute in concrete mixes actually produces different results depending on the proportion. If added as much as 10%, the concrete's compressive strength actually increases, but if it reaches 20% or 30%, the compressive strength actually decreases. This occurs because this type of wood ash has a significant water absorption capacity. As a result, the water that should be used for The chemical activity occurring between cement and water is diminished, so that the bond between the cement mixture as a binder and aggregate as a filler is reduced, and ultimately the concrete's compressive strength also decreases.

This study presents a woodcraft creation in the form of a wall clock with traditional Karo ornaments as the main visual element. The creation is driven by the urgency to preserve the visual culture of the Karo people, which is increasingly threatened by modernization, and the lack of distinctive local souvenirs in tourist areas such as Berastagi, which often offer only generic or mass-produced items. This creation aims not only to function as an indicator of time but also as a medium for cultural preservation, education, and the strengthening of the Karo visual identity in a contemporary context. The creative process applies the "three stages and six steps" approach by S.P. Gustami, which includes exploration, design, and realization. Exploration involves field observations of Karo architecture and artifacts, literary studies on Karo visual symbols, and careful selection of motifs, focusing on Tapak Raja Sulaiman, Takal Kerbo, and Pengeret-ret as representative elements rich in symbolic meaning. The design stage produces various sketches that integrate the functional aspect of the wall clock with the principles of ornamentation, ensuring both utility and cultural expression. Realization involves selecting local woods such as teak, mahogany, and jelutung, followed by manual carving techniques, the application of natural wood coloring, and protective finishing with melamine spray to ensure durability and aesthetic quality. The final result consists of twelve unique wall clocks that embody the aesthetic, symbolic, and cultural richness of the Karo people. This work demonstrates how traditional motifs can be re-contextualized into functional objects, making cultural heritage more visible and relevant in daily life, and is expected to inspire further innovation in the local crafts industry, contributing to long-term preservation and revitalization of regional cultural identity.
