description: We propose an efficient method to compute Lyapunov exponents and Lyapunov eigenvectors of long-range interacting many-particle systems, whose dynamics is described by the Vlasov equation. We show that an expansion of a distribution function using Hermite modes (in momentum variable) and Fourier modes (in configuration variable) converges fast if an appropriate scaling parameter is introduced and identified with the inverse of the system temperature. As a consequence, dynamics and linear stability properties of many-particle states, both in the close-to and in the far-from equilibrium regimes can be predicted using a small number of expansion coefficients. As an example of a long-range interacting system we investigate stability properties of stationary states of the Hamiltonian mean-field model.

description: Abstract

Tourism has a strategic role for the Indonesian economy through its contribution to the formation of GDP (Gross Domestic Product), foreign exchange earnings and employment. Kaniungan Island Tourism Area is one of the leading tourism destinations in East Kalimantan. However, analytical data shows that the tourism sector has not had an optimal impact on improving the welfare of the community around the tourist area. In improving the optimization of the role of tourism on the economy and community welfare, it is necessary to develop a sustainable and inclusive tourism development based on an adequate understanding of the characteristics of the conditions and constraints faced by creative economy-based MSME business actors in the tourism sector. Primary data was obtained from interviews with 12 expert resource persons consisting of local government, village government, Berau DPRD, banks, academics, and entrepreneurs. Secondary data came from several official government agencies at the central and regional levels. The results of this study show that the majority of businesses are mostly micro-scale, engaged in providing food and beverages, and in the form of individual businesses. The main constraints faced include technical constraints, namely limited public facilities and clean water; economic constraints, namely limited buyers and intense business competition; social constraints, namely the role of associations, assistance and training that are not yet optimal; and environmental constraints, namely the lack of environmental and waste management and rampant fish bombing. Tourism development in the Kaniungan Island area is carried out by prioritizing financing and investment to further strive for sustainability and inclusiveness. The main approach (driver) of the development is through policy, which is directed to carry out two main strategies in the form of increasing MSME businesses and the creative economy, competence and quality of human resources, and increasing connectivity, both physically and business systems between tourist destinations. The sustainable and inclusive financing and investment-based tourism development strategy in the Kaniungan Island Tourism Area comes from government collaboration.

description: (Abridged) The Long Wavelength Spectrometer (LWS) onboard the Infrared Space Observatory (ISO) observed the four large main-belt asteroids (1) Ceres, (2) Pallas, (4) Vesta, and (10) Hygiea multiple times. The photometric and spectroscopic data cover the wavelength range between 43 and 197 um, and are a unique dataset for future investigations and detailed characterisations of these bodies. The standard ISO archive products, produced through the last post-mission LWS pipeline, were still affected by instrument artefacts. Our goal was to provide the best possible data products to exploit the full scientific potential of these observations. We performed a refined reduction of all measurements, corrected for various instrumental effects, and re-calibrated the data. We outline the data reduction process and give an overview of the available data and the quality of the observations. We apply a thermophysical model to the flux measurements to derive far-IR based diameter and albedo values of the asteroids. The measured thermal rotational lightcurve of (4) Vesta is compared to model predictions. The absolute photometric accuracy of the data products was foubd to be better than 10%. The calibrated spectra will serve as source for future mineralogical studies of dwarf planets and dwarf planet candidates.

Year: 2013

description: For many protected areas, the inclusion of interested parties in decision-making processes has become both more important and common. The range of interests can lead to a variety of conflicts. Given the diversity of stakeholders, effective conflict management requires an integrated communicative approach that addresses this range interests. Yet the question remains: Are techniques developed for a specific case, and in one particular culture, applicable to other cases? To explore this question we compared the attitudes of stakeholders in Vatnajökull National Park in Iceland and Daisetsuzan National Park in Japan regarding conflict, communication and consensus. Despite the cultural and geographical distance between the two cases, the results show an 84% concurrence in stakeholder views, leading the authors to conclude that, despite minor differences, conflict management techniques can be applied across cultural borders provided that managers are sensitive to local understandings of how people relate to their social and natural environments.

Publisher: name: tourismos
Year: 2013

description: This study examines the motivational push and pull factors that affect tourists’ decision in their choice of a holiday destination. 200 questionnaires were completed using a face to face interview among specific groups of travellers to Mauritius (English, French, German, Italian and South African tourists) at various points on the island. The findings show that rest and relaxation are the most compelling push motivation forces followed by nostalgia, escape, novelty, social interaction. The key pull based motives were found to be climate and weather, landscape and scenery, flora and fauna, beaches, the exotic atmosphere, the Mauritian hospitality and authentic Mauritian culture. Push and pull factors between first time visitors and repeat visitors are discussed. This study contributes to our overall understanding of why holiday makers take travel decisions for long haul destinations like Mauritius and can therefore help destination marketers develop better marketing programmes to meet the specific needs. highly, while north Italian managers seem more concerned about issues of co-ordination and the quality of service provision.

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The standard covariant differentiation procedure for fields in vector bundles is generalised so as to be applicable to fields in general nonaffine bundles in which the fibres may have an arbitrary nonlinear structure. In addition to the usual requirement that the base space should be flat or endowed with its own linear connection, and that there should be an ordinary gauge connection on the bundle, it is necessary to require also that there should be an intrinsic, bundle-group invariant connection on the fibre space. The procedure is based on the use of an appropriate primary-field (i.e. section) independent connector that is constructed in terms of the natural fibre-tangent-vector realisation of the gauge connection. The application to gauged harmonic mappings will be described in a following article.

Importance of the advection scheme for the simulation of water isotopes over Antarctica by atmospheric general circulation models: A case study for present-day and Last Glacial Maximum with LMDZ-iso

description: Atmospheric general circulation models (AGCMs) are known to have a warm and isotopically enriched bias over Antarctica. We test here the hypothesis that these biases are partly consequences of a too diffusive advection. Exploiting the LMDZ-iso model, we show that a less diffusive representation of the advection, especially on the horizontal, is very important to reduce the bias in the isotopic contents of precipitation above this area. The choice of an appropriate representation of the advection is thus essential when using GCMs for paleoclimate applications based on polar water isotopes. Too much diffusive mixing along the poleward transport leads to overestimated isotopic contents in water vapor because dehydration by mixing follows a more enriched path than dehydration by Rayleigh distillation. The near-air surface temperature is also influenced, to a lesser extent, by the diffusive properties of the advection scheme directly via the advection of the air and indirectly via the radiative effects of changes in high cloud fraction and water vapor. A too diffusive horizontal advection increases the temperature and so also contributes to enrich the isotopic contents of water vapor over Antarctica through a reduction of the distillation. The temporal relationship, from Last Glacial Maximum (LGM) to present-day conditions, between the mean annual near-air surface temperature and the water isotopic contents of precipitation for a specific location can also be impacted, with significant consequences on the paleo-temperature reconstruction from observed changes in water isotopes.

Husband-father’s perceptions of labour and delivery
Creators: name: Leonard, Linda Gaye
Publisher: name: University of British Columbia
Year: 2010

description: This study was concerned with the husband-father['s perceptions of labour and delivery, how he perceived his role during this period, and his perceptions of the nursing care provided to his wife and himself. Sample selection was by random sampling and included twenty husbands. All were Caucasian, Canadian or British born, between the ages of twenty-two and forty years of age, and all had attended prenatal classes. Eighteen fathers attended the delivery. Seventeen were fathers for the first time and three were fathers for the second time. Data were obtained via one hour-long interview with the husband during the first three days postpartum. An interview schedule was used and contained rating scales, fixed-alternative and open-end questions. The data were subsequently analyzed by single variance analysis, nonparametric (Chi-square) tests, and by content analysis of the open-end questions. Major findings were that labour and delivery were seen as positive experiences, delivery being the most positive; that husband focus during labour was on his wife until late second stage when it shifted to the baby and to his own feelings. Labour was stressful for many, their wives' pain being a major contributor to their uneasiness. The major function of the husband in labour was cited as providing moral support, encouragement, and the provision of bodily care to his wife. Most felt that they were effective in their role but needed to confirm this with their wives. Prenatal classes were viewed as having a positive influence oh husband attitudes toward labour and delivery. The attitudes and responses of the nurses during labour and delivery were noted as having a significant effect on the husband's confidence and relaxation. The major weakness of the nursing care was the inadequate assessment, explanation, and nurse contact time during the active phase and second stage of labour. The study results have implications for the prenatal preparation of,couples, for care of the parents during labour, delivery, and the early postpartum period. Recommendations for future study centered on the need for more information about husband-father response during labour and delivery, early responses to the newborn, and information about the effects of husband-father participation in childbirth on the husband-wife-child relationship.

description: Gorontalo City embodies highly valuable tourism potentials to reveal. The city offers not only physical attractions for the tourists to please their eyes but also values of the objects that live along with the highlighted events within the historical timeline. Among the historical objects is Otanaha Fort, a tourist spot in Gorontalo, named after the place’s feature of historical legend. Many believe that stories and legends behind the naming of a place or an object are highly related to the socio-cultural life of the ancient society. With that in mind, a study is essential to carry out and to reveal the historical events that lie behind tourism objects with the aims of enriching insights of local people. Such an effort is undertaken as a support of local contents acquisition to be capable of extending the information of a tourism object for the locals. The study aims to carry out the historical overview of Otanaha Fort as a supporting element of cultural tourism in Gorontalo. The researchers employed field survey and interview to obtain the data and folklore analysis to approach the research object. The result shows that the folklore of Otanaha Fort is a manifestation of features of social events of Gorontalo in the ancient times that depict the record of past events. The historical facts are further packaged in the form of imaginative fable for people to enjoy as an act of historical preservation. The evidence of the historical facts is observable by data tracking within the naming process of the objects, site or tombstone of influential figures of the story, preservation of address of traditional titles related to the figures, and distinct building techniques observable in the fort’ architecture.

description: Recent studies have revealed that neural combinatorial optimization (NCO) has advantages over conventional algorithms in many combinatorial optimization problems such as routing, but it is less efficient for more complicated optimization tasks such as packing which involves mutually conditioned action spaces. In this paper, we propose a Recurrent Conditional Query Learning (RCQL) method to solve both 2D and 3D packing problems. We first embed states by a recurrent encoder, and then adopt attention with conditional queries from previous actions. The conditional query mechanism fills the information gap between learning steps, which shapes the problem as a Markov decision process. Benefiting from the recurrence, a single RCQL model is capable of handling different sizes of packing problems. Experiment results show that RCQL can effectively learn strong heuristics for offline and online strip packing problems (SPPs), outperforming a wide range of baselines in space utilization ratio. RCQL reduces the average bin gap ratio by 1.83% in offline 2D 40-box cases and 7.84% in 3D cases compared with state-of-the-art methods. Meanwhile, our method also achieves 5.64% higher space utilization ratio for SPPs with 1000 items than the state of the art.

Avanguardia o sopravvivenza:  il Gruppo 70 e la dischiusura del campo letterario

Year: 2014
Subjects: Antonio Scurati; Gruppo 70; Lamberto Pignotti; Neo-Avant-Garde; Rethorics

description: This article presents literature as a vital and irreplaceable form of human culture. It does so by discussing various prominent works by Gruppo 70, which already by 1963 had conceptualized literary conscience as beyond literature per se. Scurati declared that the necessary broadening of the literary field emerged from the conviction that our literary conscience “is, today, largely integrated, if not mostly integrated, by the use of works which are not mediated by written words”. On the other hand, Lamberto Pignotti’s presentation at the “Art and Communication” symposium (May 1963) underlined how “avant-garde after avant-garde” represented the only survival option for literature in a neo-capitalist society. This article starts from this discussion to analyse the clash between a “closed literature” definition – whereby aesthetic differences imply meaning and value – and an “open literature” definition – literature as a vital and irreplaceable form of human culture. It does so by discussing various prominent works by Gruppo 70.

description: The dP Salsa covers a geographical area of great value for biodiversity that has been highlighted since the end of the 19e century, as shown in the thematic map. Within this context, the map also illustrates the coherence between the countries involved in the construction of the dP: the Philippines, Malaysia, Indonesia, etc. This thematic map illustrates biodiversity jumps which suggest a zone of interest where high biodiversity meets high human pressure. The thematic map presented here is simplified from Raes & van Welzen, in Blumea 54, 2009, 6-8(3). Zollinger (1887) first observed a zone of unusually high biodiversity in between Asia and Oceania, and called it the "Malesian floristic region", and its the delimitations were precised by Van Steenis (1948, 1950) with three demarcation knots (North to peninsular Malaysia from 375 to 200 genera, north to Philippines from 421 to 165, and between papua New Guinea and Australia from 644 to 340). The numbers indicate the number of botanic genera that do not crossing the knots, illustrating a higher endemicity within the zone. The green lines indicate ecotones separating biogeography zones between asia and oceania, with the Wallace lines and the eastern and western variants by different authors. The "Zollinger" zone correspond to the countries represented in yellow. The "Wallacea" zone varies a lot according to authors, but is often understood as a smaller zone comprising Sulawesi and Molucca archipelagoes.

description: Abstract

This study evaluates the technical efficiency of small-scale 'Bungulan' banana farming in Cotabato, Philippines, crucial for enhancing productivity. Given the Philippines' prominence as a banana exporter, it aims to identify factors impacting technical efficiency and address local challenges. Using stochastic frontier analysis, 182 members of the Organic Banana Producers Association (OBPA) were sampled through stratified techniques. These farmers, engaged in 'Bungulan' farming for over three years on land under 10 hectares, provided primary and secondary data. Results showed 43.96% of farms had efficiency levels below 0.50, and only 3.30% achieved near-optimal efficiency (>0.90). Key findings include the significant impact of quality planting materials on efficiency (coefficient: 3.76). Increased production correlates with higher efficiency, while family labor and training programs show mixed effects. Regular extension contacts and proximity to markets reduce inefficiency, emphasizing advisory services and market access. Recommendations include improving planting materials, optimizing labor, and enhancing training, extension services, and infrastructure.

description: E-learning for over fifteen years has evolved from a simple instrument for virtual educational interactions (1.0) to an environment capable of promoting wide participatory experiences (2.0). Recently, Open philosophy has given rise to new ways of designing and using courses, while Open Educational Practices (OEP) have encouraged the use and reuse of online educational resources. Internet is no longer only a channel, since it increasingly appears as an environment offering new opportunities for discovering and questioning acquired knowledge. These new trends should also allow small-medium universities or individual members of teaching staff to renew institutional practices improving educational quality. In this article, we propose a modality called Open Educational Path (OEPath®), a methodological variation of e-learning, within the OEP. Openness is understood in a critical-cognitive way, as “openness to the ongoing restructuring of knowledge and its sharing”. Students are encouraged to actively participate, depending on their expertise, in enriching and revising the learning path.

description: Basically, many developed any developing countries need to expand tourism activities for accessing to the goals of national economic development and attracting foreign funds, therefore evaluating the efficiency of tourism industry can have significant help in recognizing the existed tourism potentials. The Chabahar zone in spite of numerous potential abilities in attracting domestic and foreign tourists and despite the fact that it is known as one of the important poles of tourism in Iran, but it is not so successful in attracting tourists. The present research has been provided to access to the efficiency of tourism industry in this area. For analyzing the information, the Data Envelopment Analysis Method (DEA) have been used. According to the results, the technical, management and scale efficiencies are 0.58, 0.69 and 0.84 percent respectively. It is suggested to strengthen the marketing, advertising and doing appropriate transportation infrastructure by employing manpower and efficient and expert management.

description: Abstract

This study was conducted to determine the relationship between learning strategies and technical writing competency of senior high school students of Region XII. This study utilized the quantitative causal method. Four hundred respondents were selected using stratified random sampling. The respondents answered the survey questionnaire through Google Form. The mean, Pearson r, and regression were used in the analysis of data. Results showed that the learning strategy and technical writing were high and found that learning strategies significantly relate to students' technical writing ability. The strong correlation highlights that students who effectively employ cognitive, behavioral, and self-regulatory strategies are more likely to excel in technical writing. It suggests that learning strategies enhance students' knowledge, skills, and attitudes towards technical writing, leading to better academic outcomes. Consequently, educators may emphasize the development of learning strategies to improve students' technical writing proficiency, ultimately contributing to their overall academic and professional success.

description: Motivated by Weinberg's asymptotic safety scenario, we investigate the gravitational renormalization group flow in the Einstein-Hilbert truncation supplemented by the wave-function renormalization of the ghost fields. The latter induces non-trivial corrections to the beta-functions for Newton's constant and the cosmological constant. The resulting ghost-improved phase diagram is investigated in detail. In particular, we find a non-trivial ultraviolet fixed point in agreement with the asymptotic safety conjecture, which also survives in the presence of extra dimensions. In four dimensions the ghost anomalous dimension at the fixed point is $η_c^* = -1.8$, supporting space-time being effectively two-dimensional at short distances.

description: Networks of optical oscillators simulating coupled Ising spins have been recently proposed as a heuristic platform to solve hard optimization problems. These networks, called coherent Ising machines (CIMs), exploit the fact that the collective nonlinear dynamics of coupled oscillators can drive the system close to the global minimum of the classical Ising Hamiltonian, encoded in the coupling matrix of the network. To date, realizations of large-scale CIMs have been demonstrated using hybrid optical-electronic setups, where optical oscillators simulating different spins are subject to electronic feedback mechanisms emulating their mutual interaction. While the optical evolution ensures an ultrafast computation, the electronic coupling represents a bottleneck that causes the computational time to severely depend on the system size. Here, we propose an all-optical scalable CIM with fully-programmable coupling. Our setup consists of an optical parametric amplifier with a spatial light modulator (SLM) within the parametric cavity. The spin variables are encoded in the binary phases of the optical wavefront of the signal beam at different spatial points, defined by the pixels of the SLM. We first discuss how different coupling topologies can be achieved by different configurations of the SLM, and then benchmark our setup with a numerical simulation that mimics the dynamics of the proposed machine. In our proposal, both the spin dynamics and the coupling are fully performed in parallel, paving the way towards the realization of size-independent ultrafast optical hardware for large-scale computation purposes.

description: The existence and origin of large spatial temperature fluctuations in HII regions and planetary nebulae are assumed to explain the differences between the heavy element abundances inferred from collisionally excited and recombination lines, although this interpretation remains significantly controversial. We investigate the spatial variation in electron temperature inside NGC 346, the brightest HII region in the Small Magellanic Cloud. Long slit spectrophotometric data of high signal-to-noise were employed to derive the electron temperature from measurements derived from localized observations of the [OIII]($\lambda4959 + \lambda5007)/\lambda4363$ ratio in three directions across the nebula. The electron temperature was estimated in 179 areas of 5$^{\prime\prime}\times1.5^{\prime\prime}$ of size distributed along three different declinations. A largely homogeneous temperature distribution was found with a mean temperature of 12 269 K and a dispersion of 6.1%. After correcting for pure measurements errors, a temperature fluctuation on the plane of the sky of $t^2_{\rm s} = 0.0021$ (corresponding to a dispersion of 4.5%) was obtained, which indicates a 3D temperature fluctuation parameter of $t^2 \approx 0.008$. A large scale gradient in temperature of the order of $-5.7\pm1.3$ K arcsec$^{-1}$ was found. The magnitude of the temperature fluctuations observed agrees with the large scale variations in temperature predicted by standard photoionization models, but is too small to explain the abundance discrepancy problem. However, the possible existence of small spatial scale temperature variations is not excluded.

description: We study the polarized infrared emission by Polycyclic Aromatic Hydrocarbons (PAHs), when anisotropically illuminated by UV photons. PAH molecules are modeled as planar disks with in-plane and out-of-plane vibrational dipoles. As first pointed out by Leger (1988), infrared emission features resulting from in-plane and out-of-plane modes should have orthogonal polarization directions. We show analytically how the degree of polarization depends on the viewing geometry and the molecule's internal alignment between principal axis of inertia and angular momentum, which gets worse after photon absorption. Longer wavelength features, emitted after better internal alignment is recovered, should be more strongly polarized. The degree of polarization for uni-directional illumination (e.g., by a star) is larger than for diffuse illumination (e.g., by a disk galaxy), all else being equal. For PAHs in the Cold Neutral Medium, the predicted polarization is probably too small to distinguish from the contribution of linear dichroism by aligned foreground dust. The level of polarization predicted for PAH emission from the Orion Bar is only ~0.06% at 3.3 microns; Sellgren et al. (1988) report a much larger value, 0.86+-0.28%, which suggests that the smallest PAHs may have moderately suprathermal rotation rates. Future observations of (or upper limits on) the degree of polarization for the Orion Bar or for dust above edge-on galaxies (e.g., NGC 891 or M82) may constrain the internal alignment of emitting PAHs, thus providing clues to their rotational dynamics.

description: Novel 1,3,5-trinitro-1,3,5-triazine/3,3-bis (azidomethyl) oxetane-tetrahydrofuran copolymer (RDX/BAMO-THF) energetic nanocomposites were successfully prepared by a facile sol–gel freezing–drying method. The as-prepared RDX/BAMO-THF energetic nanocomposites were characterized by Raman and Fourier transform infrared spectroscopy, which revealed that RDX particles were incorporated into BAMO-THF gel matrix. Scanning electron microscopy was used to characterize the morphology and the particle size of the as-obtained samples. The results showed that RDX particles were trapped in the BAMO-THF gel matrix and the particle sizes were in nanoscale. Differential thermal analyzer (DTA) was performed to determine the thermal decomposition behaviors of BAMO-THF, raw RDX and RDX/BAMO-THF nanocomposites. The results indicated that the thermal decomposition process of RDX/BAMO-THF nanocomposites was enhanced compared with that of BAMO-THF and RDX. The kinetic, thermodynamic and thermal stability parameters were calculated according to DTA analysis. The calculated results revealed that RDX/BAMO-THF nanocomposites presented high thermal reactivity. The results of impact sensitivities for RDX/BAMO-THF nanocomposites indicated the sensitivity was effectively reduced compared to raw RDX.

description: In this Letter, we measure the full orbital architecture of the two-planet system around the nearby K0 dwarf 14 Herculis. 14 Her (HD 145675, HIP 79248) is a middle-aged ($4.6^{+3.8}_{-1.3}$ Gyr) K0 star with two eccentric giant planets identified in the literature from radial velocity (RV) variability and long-term trends. Using archival RV data from Keck/HIRES in concert with \textit{Gaia-Hipparcos} acceleration in the proper motion vector for the star, we have disentangled the mass and inclination of the b planet to ${9.1}_{-1.1}^{+1.0}$ $M_\mathrm{Jup}$ and ${32.7}_{-3.2}^{+5.3}$ degrees. Despite only partial phase coverage for the c planet's orbit, we are able to constrain its mass and orbital parameters as well to ${6.9}_{-1.0}^{+1.7}$ $M_\mathrm{Jup}$ and ${101}_{-33}^{+31}$ degrees. We find that coplanarity of the b and c orbits is strongly disfavored. Combined with the age of the system and the comparable masses of its planets, this suggests that planet-planet scattering may be responsible for the current configuration of the system.
DEVELOPING EQUATIONS FOR ESTIMATING CORROSION OF DUCTILE IRON AND CARBON STEEL PIPELINES

description: Abstract

The distribution system's efficacy and reliability are greatly affected by the water quality in the pipelines. It is common practice to measure water's scaling or corrosive potential using the Langelier Saturation Index (LSI). The most common issues with drinking water facilities caused by corrosion and scaling include water loss, reduced facility life, pipe punctures, pipe clogging, and pressure loss in distribution systems. This paper aims to develop equations for calculating the pipe mass loss due to pipe corrosion that is subjected to water characteristics of PH, alkalinity, calcium hardness, TDS, and temperature, which give negative LSI indicators. Ten identical samples, five ductile iron sheets and five carbon steel sheets with dimensions of 5 x 3 x 2 cm were subjected to water with LSI indicator values of -0.2, -0.5, -1, -3, and -5. The sheet mass loss was recorded every seven days. Two equations for the two used pipe material types were developed to calculate the mass loss for any LSI indicator value at a given time. It was found that the mass loss due to pipe corrosion for ductile iron pipes was less than that of the carbon steel pipes.

description: Recently, it was shown that a simple empirical formula, in terms of the mass and valence nucleon numbers, can describe the main trends of the yrast excitation energies of the natural parity states up to $10^+$ in even-even nuclei throughout the entire periodic table. The same empirical formula was applied to the yrast excitation energies of unnatural parity states including $1^+$, $2^-$, $3^+$, $4^-$, $5^+$, $6^-$, $7^+$, $8^-$, $9^+$, $10^-$, and $11^+$ in even-even nuclei. Although the overall character of the effective residual interaction for the unnatural parity states was quite different to that of the natural parity states, the same form of the empirical formula was found to hold reasonably well for the yrast excitation energies of the unnatural parity states.

description: Abstract

This paper explores the application of the Business Model Canvas (BMC) to Baso Aci Akang, a small and medium-sized enterprise (SME) in the Indonesian culinary sector, to illustrate the strategic benefits and insights this tool can provide in enhancing business operations and competitive positioning. Through a detailed analysis of Baso Aci Akang’s application of the BMC, the study demonstrates how each of the nine components—Customer Segments, Value Propositions, Channels, Customer Relationships, Revenue Streams, Key Resources, Key Activities, Key Partnerships, and Cost Structure—can be optimized to align more closely with market demands and consumer preferences. The findings reveal that Baso Aci Akang’s focus on digital engagement and customer-centric strategies has significantly enhanced its market presence and operational efficiency. The paper discusses the implications of these strategies for other SMEs in the culinary sector, emphasizing the importance of digital marketing, customer relationship management, and continuous innovation. It also suggests that integrating sustainability practices into the business model can further enhance competitive advantage. Future research directions are proposed, highlighting the need for cross-cultural studies on the BMC’s adaptability, the impact of emerging technologies, and the integration of sustainability practices within SME business models. This study contributes to the literature on strategic management and business model innovation, offering practical insights and a framework that other SMEs can adapt for their contexts, ensuring resilience and growth in a dynamic market environment.
