Published: September 2024

Wilayah di Indonesia yang merupakan sentra produksi bawang merah salah satu diantaranya adalah Kabupaten Cirebon dengan produksi 14.976 ton tahun 2014 (BKP5K, 2015) atau menyumbang produksi 1,21% dari total produksi bawang merah nasional 1.233.984 ton tahun 2014 (Ditjen Hortikultura Kementan, 2015). Namun keadaan tersebut masih belum memberikan penghasilan pendapatan yang wajar bagi petani disebabkan modal yang tinggi, juga fluktuasi harga jual produk yang sulit diprediksi petani karena adanya permainan harga oleh para pedagang yang cenderung dominan menguasai harga pasar. Hal tersebut berakibat sekitar 80% petani melakukan jalan pintas dengan menjual produknya secara tebasan. Tujuan penelitian ini adalah (1) Mengetahui profil sosio-demografis petani responden gabungan menjual tebasan dan non tebasan; (2) Mengetahui struktur komponen biaya tunai dalam sistem produksi bawang merah; (3) Mengetahui selisih pendapatan dan perbandingan pengembalian (return) penjualan tebasan dan non tebasan. Adapun target khusus yang ingin dicapai adalah kemandirian petani responden untuk menghasilkan bibit berkualitas dengan penangkaran benih. Untuk menetapkan lokasi penelitian menggunakan metode dengan pendekatan “purposive” atau langsung berdasarkan kriteria target sasaran produksi bawang merah di Kabupaten Cirebon pada periode musim tanam tahun 2017. Kegiatan penelitian diawali dengan prasurvei/survei non formal pada instansi terkait lingkup Kabupaten Cirebon. Lebih lanjut kumpulan informasi hasil prasurvei digunakan sebagai acuan untuk menyusun daftar pertanyaan atau kuesioner survei formal. Penetapan petani responden atau sampel menggunakan pendekatan dengan teori Gay et al (1992) yang menyebutkan bahwa besarnya sampel minimal 10 % dari jumlah populasi bilamana pupulasi terlalu kecil (N < 60), maka jumlah sempel minimal adalah 20% , dan teknik pemilihan sampel menggunakan pendekatan “stratified random sampling”Kata kunci : Bawang merah, tebasan non tebasan, pendapatan.

The lack of public open space due to the land competition in urban area generates less activity to gather in community, because of this changing of the life style, people who used to gather in public open spaces now moving to gather in modern shopping centers. This led to the development of shopping center design that integrated with public open space as a forum for the community to gather. This research takes a case study in Paris Van Java Mall Bandung (West Java), Mall Kelapa Gading (DKI Jakarta), and Lippo Mall kemang (DKI Jakarta). These three shopping centers is integrated with public open space. The purpose of this research is to find a form of integration of public open spaces to the shopping centers, especially in the aspect of circulation, zoning activities, and visual space. The method use in this research is descriptive qualitative method with a case study approach. Methods of data collection are using place-centered mapping and person-centered mapping. The results of this research indicate that circulation aspects use camouflaging approach by the linear arranged retails, that visitors can pass through the space between retails whose circulation form with semi open space. The aspect of zoning activity will form zoning receiver, zoning connections, zoning support (retail, sitting area, garden), and multiuse zoning. The aspect of visual space will be dominated by the space and the principle of rhythm, so that the visual of the space would provide unity between public open space and shopping center.Keyword: integration, public open space, shopping center

Transit Oriented Development (TOD) is an approach to developing cities that adoptsa spatial mix of commercial and mixed use residential areas designed to maximizeaccess to public transportation and combine features to encourage transit passengersby maximizing the use of mass transportation such as Busway or BRT, Mass RapidTransportation ( MRT), Light Rail Transit (LRT), and equipped with a pedestrian orbicycle network. Thus the trip will be dominated by using public transportation that isconnected directly to the purpose of the trip. Public transport stops, especially airports,have relatively high densities and are usually equipped with facilities such as arrivalcorridors, boarding lounges, baggage claims, parking lots and more. Soekarno-HattaAirport is one of the largest airports which is the main gateway in Indonesia, whichwas built since 1985. It has applied this TOD concept to its ultimate terminal 3management. Over time, the passenger service capacity which was originally only 22million PAX was inadequate due to current conditions because based on a surveyfrom Airport Council International in 2013 the number of passengers at SoekarnoHatta Airport had reached 52 million PAX. To overcome the density of passengersand air traffic, the development of Soekarno Hatta Airport facilities is very necessaryto improve the quality of service and the convenience of airport service users.Keywords: Transportation, Transit, Development, Commercial, Residential

Individual Responses to Paradox: The Articulation Between Emotion and Cognition
Authors: Santistevan Diana , Thélisson Anne-Sophie , Vo Linh-Chi
Published: September 2024

This article examines how emotions and cognition work together to shape individual responses to paradox. While much-existing research focuses on organizational response or the effect that either emotions or cognitions have on individual responses, our work shows how emotion and cognition work together to create individual responses. Based on a qualitative study of a global organization with employees who regularly face paradoxes, we found two cognitive appraisals (perception regarding the difficulty of managing paradoxical tensions and self-perception of leadership role) that either generate emotion or regulate response. By examining the interlinking of appraisal – emotion – appraisal – response, we identify two mechanisms that demonstrate the articulation between emotion and cognition: the nonregulated response and the regulated response. We contribute to the existing literature by detailing each mechanism and explaining how emotions and cognition work together to shape individual responses.
Collective Action for a Multispecies World: A Compositionist Approach to Grand Challenges
Authors: Mercier-Roy Mireille , Mailhot Chantale
Published: September 2024

As the field of management studies widens its scale of reflection to consider the socio-ecological ecosystems of which organizations are part, more attention is devoted to grand challenges. While extent literature generally treats them as exogenous objects, our focus here is on unfolding encounters with grand challenges. We conceive grand challenges as concrete problems of arbitration of more-than-human ways of life, where the managerial practices of organizations enact and transform grand challenges. We put forward a posthumanism and pragmatist style of thinking, which, we argue, can help us think with grand challenges and engage in creative ways of composing a common world. Through the story of a problematic situation where tangles of grand challenges abound, we offer a mode of construction that can help us compose what is, in a given situation, a ‘better’ world. This mode of construction is based on three sets of practices, namely, slowing down, multispecies world-making, and being present and grieving losses. It facilitates the emergence of new ways of composing the world, helps account for the implication of other species, and foregrounds the elaboration of worlds in a response-able way. Our paper contributes to the grand challenges literature by proposing a mode of attention and action that engages both management researchers and practitioners in the work of constructing multispecies worlds.

This paper presents an innovative approach to designing and analyzing a simulated piezoelectric energy harvesting system for electricity generation, employing various array connections using Proteus software. The ingenious concept of harnessing energy from rainfall through piezoelectric technology has become an exciting way to turn a common natural occurrence into a possible power source. The rainfall energy harvesting introduces a novel approach that capitalizes on the mechanical energy imparted by raindrops as they strike surfaces, such as rooftops, pavements, or specially designed structures. This study explores distinct piezoelectric connection types to determine their impact on output voltage, focusing on applications such as rechargeable battery and LEDs. The system begins by harvesting vibration and applying it to the piezoelectric disc. The investigation prioritizes identifying the optimal array connection design. Array configurations of series (S), parallel (P), and combination of series-parallel (SP) are assessed in the simulation. Notably, the series connection of 10 units of piezoelectric elements yielded the highest output voltage at 8.5V. The findings provide valuable insights into finding the optimal array connections in enhancing piezoelectric electricity generation. This research contributes to the leading of potential applications of piezoelectric energy harvesting from rainfall, offering insights into a greener and more self-sufficient energy future.

Published: September 2024

The dynamic behaviour of Hemic peat in Johor, Malaysia is described. The index properties of three different locations in Johor were investigated. Cyclic triaxial test with different frequencies and effective stresses were applied to correlate the characteristics behaviour of Johor peat. By using the Cyclic Triaxial machine located in the Research Centre of Soft Soil, Universiti Tun Hussein Onn Malaysia, the tests conducted referred to the British Standard and ASTM. The result of cyclic shear modulus shows that hemic peat in Johor indicated less than 2MPa and damping ratio in the range of 7.70% to 24.84%. The influences for the cyclic shear modulus correlations in this research are mostly affected by the effects of fibres structures and the natural characteristics of peat. The different behaviour of fibres in peat also significantly influenced the results. These behaviours lead to a different performance of each sample used. The natural characteristics of peat results in varied and scattered behaviour. Through this assessment, the peat characteristic is significantly depending on the well-structured of hemic peat which mostly consists of fibres, water and pores that controls its behaviour during the cyclic loading test.

Known as a problematic soil in the civil engineering field, a sustainable solution to marine clay soil strength behaviour is needed. Another major concern in the engineering field is the solid waste management. Demolished Tile Material (DTM) is one of the largest contributors to construction waste. By utilizing DTM as a stabilizer product to treat marine clay soil, both problems can be minimized. The primary objective of this study is to assess the improvement in marine clay soil's strength characteristics through the addition of DTM and cement. Various proportions of DTM (4%, 8%, 12%, 16%, and 20%) were incorporated into the soil, with a constant 10% cement content. Unconfined Compressive Strength (UCS) measurements were taken at different curing times (0, 7, 14, 28, and 60 days). Results indicate a significant increase in UCS after treating marine clay with DTM and cement, with the most substantial improvement observed at 16% DTM content. The study also emphasizes the role of curing time in enhancing soil strength. The research findings shows that the potential of repurposing DTM for soil stabilization, reducing construction waste, and promoting environmentally responsible construction practices. This study also contributes to the sustainable development of marine clay areas in Malaysia and offers valuable insights for soil engineering and waste management in construction projects.

Published: September 2024

Essential oils (EOs) have been used in numerous industries for ages including pharmaceutical, textile and food. Microencapsulation formulation and techniques are important to enhance the EOs characteristics and stability which could directly influence the yield and quality of EOs. This research paper evaluated the effect of using different solvents and stirring time on thymol EO microcapsules. Ethanol and methanol were used as solvents to encapsulate the core and wall material using a simple coacervation method. The microcapsules were collected at various time intervals which were 15, 30, 45, 60, 90, 120, 150, and 180 minutes. It has been noted that the stirring time influenced the size of microcapsules. Using Thymol oil, ethyl cellulose, methanol and polyvinyl alcohol (TM) produces the most microcapsules at 120 minutes of stirring time. The biggest microcapsule diameter was recorded at 90 min stirring time using formulation of thymol oil, ethyl cellulose, ethanol, and polyvinyl alcohol (TE). The encapsulation efficiency (EE) of both samples are 64.55% and 72.16%, respectively.

Published: September 2024

Rear-end collisions involving trucks can have a direct impact on the safety of vehicle occupants, particularly due to the crashworthiness of the truck's rear-end under-run bar. These types of accidents, which occur between small vehicle and truck, contribute significantly to fatalities and serious injuries, presenting a significant public safety concern. This research paper aims to examine the collision effects on the rear-end under-run bar of a truck and its behaviour when it collides with another vehicle. The study employed the finite element method and simulated the under-run bar and impactor collisions using finite element software. The entire structure of the rear-end under-run bar had been designed, taking into account real parameters. The under-run bar structure was made of steel, and the impactor had a mass of 115kg, which resembled the mass of a motorcycle. A predefined field feature was utilized to apply a velocity of 30km/h to the impactor, which had a cylindrical shape. The element size of the mesh for the under-run bar was determined by using the mesh sensitivity technique. The simulation was tested a few times by using different sizes of elements. It is shown that the force reached a peak value of 28kN at a displacement of 68.25 mm, corresponding to the maximum under-run bar displacement. The data revealed that the energy absorbed increased from time 0.003s to 0.012s, reaching its peak value of 11.08kJ at 0.012s. The results show convincing results and prove the capability of rear-end under-run bar to be simulated and analysed using finite element simulation.

Authors: Mohammad Mazian , Othman Abdul Rahim , Epin Vorathin , Idris Naila Rusma , Ramli Siti Haslina
Published: September 2024

Composite materials are widely used as repair materials in the oil and gas sector, particularly for vessels, piping, and pipelines. Inspection and monitoring of these composite repairs is a critical aspect of ensuring their integrity and long-term performance. The reason being that failure of composite repairs may lead to loss of production and incur additional costs for re-repair or equipment replacement. Conventionally, a visual inspection is generally performed to observe any irregularities on the external surface of the composite repairs. This will usually be followed by a series of Non-destructive Tests (NDT) to identify the extent of the damage. However, these NDT methods, merely allowing off-line testing in a local manner with complicated and heavy equipment, require extensive and time-consuming labour. Structural Health Monitoring (SHM) based on Fibre Bragg Grating (FBG) that utilizes strain-based signals is one of the best options for monitoring the damage mechanism in composite due to its unique advantages of light weight, high stability and reliability, a long-life cycle, and the ability to capture the online reading. In this paper, the application of the FBG monitoring approach was used to examine the strain characteristics of composite materials based on mechanical tests (tensile and flexural). Three types of samples were prepared to simulate the type of damage mechanism: healthy, delamination, and disbondment. Based on the results, it was shown that the FBG sensor has potential for detecting and distinguishing the types of failure mechanisms in composites, including cracks, delamination, and disbondment. Hence, it was suggested that the FBG sensor technology could be used for site deployment in industry.

Published: September 2024

Conventionally, researchers have primarily focused on developing gravity-compensation robots without considering the voluntary resistant force in continuous passive motion (CPM) therapy. This leads to critical limitations in robot-assisted therapy compared to conventional therapy administered by therapists, particularly in terms of generating natural behavioural responses in patients. To address this limitation, our proposed technique aims to investigate model-based dynamic force estimation specifically related to intrinsic muscular force in order to develop a robotic-human-like controller for CPM therapy. We conducted an estimation of the muscular force based on surface electromyography (sEMG) signals using Ridge Polynomial, Artificial Neural Network (ANN), and Support Vector Machine (SVM) approaches. Strategic preprocessing and model optimization procedures were implemented. The optimized results demonstrate that ANN exhibits slightly superior performance enhancing the accuracy and precision with its quicker testing time. Moreover, the substantive results demonstrate a notable comparison between the use of conventional gravity compensation and our novel technique which integrates both intrinsic muscular force and gravity compensation. It reveals that our approach yields calculated voluntary forces that more closely approximate to the actual values in comparison to the conventional method. In conclusion, this research makes a significant contribution to the development of a smart robotic controller offering high-accuracy measurement of voluntary forces for CPM therapy, thereby facilitating natural behavioural responses.

The Wing-in-Ground (WIG) craft represents a pioneering vehicular innovation that exploits aerodynamic lift via a cushioning mechanism, enabling it to remain suspended above the water's surface. A notable concern encountered during the navigational manoeuvres of the WIG craft over the uneven sea terrain pertains to its potential impact on fuel efficiency during flight durations. This research objective is focused on the pivotal of ascertaining the optimal lifting force prerequisites for a prototype WIG craft. This comprehensive study entails an exploration of diverse combinations of velocities and angles of attack (AoA) to identify the most suitable configuration capable of attaining the requisite lift force levels. The study's methodology revolves around the adaptation of the actual WIG concept, encompassing a focus on the aerofoil profile and leveraging insights garnered from a design concept pertaining to WIG craft. To emulate real-world scenarios with precision, computational simulations employing the flow simulation capabilities of SolidWorks software are executed concurrently with the validation of a fabricated prototype. Parameters encompassing, angle of attack, and velocity are meticulously configured, adhering to the commonly employed parameters within the realm of WIG craft operations. The resulting outcomes are rigorously validated and subsequently compared against a lift coefficient of 1.25 at an angle of attack set at 16°, consistent with outcomes from prior research activities. This established angle of attack serves as a foundational reference for the present study's empirical conclusions. The culmination of these simulations yields the identification of an optimal arrangement characterized by a velocity of 120 km/h coupled with an angle of attack measuring 20°. This particular configuration consistently stimulates the requisite magnitude of lift force, thereby demonstrating the feasibility of elevating the WIG craft prototype without compromising stability or safety.

Animal milk has been consumed by humans for a very long time. In the food industry, the probiotic Lactobacillus is regarded as a good substitute to lower the risk of food-borne illnesses. The bacteria Lactobacillus aids in the body’s nutrient absorption, digestion, and defense against pathogens. Determination of Lactobacillus from unfermented and reconstituted Milk. The initial and biochemical tests allowed for the identification of the organisms. The two pathogens, identified as Escherichia coli and Staphylococcus aureus were isolated in light of the findings. The purpose of these two pathogens, selection was antagonistic research. With the cross-stretched method, the antagonistic activity test was conducted. The outcome demonstrates that there is more inhibition displayed by the Lactobacillus grown in buffalo milk. In an antagonistic test, the probiotic organism inhibits the test pathogens.
High School Students’ Perceptions towards COVID-19 Vaccination: Benefits, Barriers and Influencing Factors

After the outbreak of the Corona pandemic and its conquest of the world, it became necessary to find a vaccine against the Corona virus in order to break the cycle of its spread, but the acceptance or rejection of the vaccination by the citizens may be affected by the mental and representational maps that have stuck to the epidemic through the emergence of several trends. Some researchers have observed that the large population has a relatively high reluctance to current vaccinations and that vaccination coverage is not adequate (van Doremalen et al 2020; Harapan et al. 2019). In Morocco, the elderly have, it seems, readily accepted to participate in the vaccination campaign launched by the government. But what is the attitude of young people towards vaccination against COVID 19? This study aims to understand the perceptions towards the COVID-19 vaccination and the targeted subject is the high school students (17-18 years old). The research used five-point Likert scale instruments to examine student’s perceptions of the COVID-19 vaccination. The sample for this analysis is N=263 participants. Through the analysis that targeted the students’ answers about the advantages of vaccination, it was found that vaccination against the Corona virus has several advantages for students of the second year of the baccalaureate, as both scientific and literary students acknowledge that it combats the disease, but the percentage of importance varies from scientific to literary. Statistics from both categories of students indicated that literary people consider the vaccine against the Corona virus to be ineffective, while scientists do not. The results also showed that there are more risks of unwanted negative side effects than benefits. Statistics have also shown that among the obstacles that would prevent students from getting vaccinated against the virus, in addition to fear of the vaccine, doubt about its safety. Both science and literary students indicated that the school, the free vaccination, the media, the Internet, and the family are some important factors that may affect students' receipt of the vaccination. The comparison between the two groups of students showed that there are no significant differences between the students regarding the COVID-19 vaccination process, and from this we can assume that the information obtained by the science students did not affect their perceptions.

Endodontic instrument fracture is a procedural error that creates a significant barrier to routine root canal therapy. A separated instrument results in insufficient cleaning and shaping of the root canals. Inadequate biomechanical preparation has an impact on the result and outcome of root canal treatment. Therefore, retrieval of separated instruments should be considered important. There are many instrument retrieval kits and techniques available for this purpose. In this case report, a separated rotary file was successfully retrieved using a Masserann kit .

Logistics is currently undergoing a transformative phase due to rapid digitalization, prompting a profound exploration of both theoretical potentials and practical challenges within the industry. This comprehensive review delves deeply into the growing interest in digital technologies within logistics, with a specific emphasis on their practical applications. This study aims to conduct a bibliometric analysis to explore the growth and academic focus on the logistics digitalization. Academic literature is studied from the Web of Science database for 2020–2024. Literature review and bibliographic analysis of selected articles are performed using VOS Viewer. It was identified that one of the clusters comprise keywords related to logistics and information technology. The analysis of investments in digital technology reveals experiences of the logistics sector seeking to figure out how investments impact labor productivity. The descriptive analysis results indicate that companies implementing technology can achieve up to a 20% increase in labor productivity, signifying the importance of technology investments for business competitiveness increase. These findings illuminate how various logistics sub-sectors respond to software and computers investments and the pace at which these technologies influence labor productivity metrics. These empirical findings considerably fortify the theoretical framework, offering practical implications and stressing the critical necessity for logistics firms to seamlessly adopt digital technologies into their operational frameworks. In conclusion, as the logistics landscape teeters on the brink of a digital revolution, businesses must navigate and fully embrace digital solutions to maintain competitiveness.
Water Evolution and Inventories of Super-Earths Orbiting Late M Dwarfs

Published: September 2024

Super-Earths orbiting M dwarf stars may be the most common habitable planets in the Universe. However, their habitability is threatened by intense irradiation from their host stars, which drives the escape of water to space and can lead to surface desiccation. We present simulation results of a box model incorporating deep-water cycling between interior and atmosphere and water loss to space for terrestrial planets of mass 1–8 M
⊕ orbiting in the habitable zone of a late M dwarf. Energy-limited loss decreases with planetary mass, while diffusion-limited loss increases with mass. Depending on where it orbits in the habitable zone, a 1 M
⊕ planet that starts with 3–8 Earth Oceans can end up with an Earthlike surface of oceans and exposed continents; for an 8 M
⊕ super-Earth, that range is 3–12 Earth Oceans. Planets initialized with more water end up as waterworlds with no exposed continents, while planets that start with less water have desiccated surfaces by 5 Gyr. Since the mantles of terrestrial planets can hold much more water than is currently present in Earth’s atmosphere, none of our simulations result in Dune planets—such planets may be less common than previously thought. Further, more water becomes sequestered within the mantle for larger planets. A super-Earth at the inner edge of the habitable zone tends to end up as either a waterworld or with a desiccated surface; only a narrow range of initial water inventory yields an Earthlike surface.
