Authors: Mainali Divesh , Shrestha Hari Mohan , Pokhrel Sudip
Published: February 2024

The satisfaction of employees in their jobs holds a substantial influence on the overall success and effectiveness of an organization. This study is focused on evaluating the factors that directly affect the job satisfaction of civil engineers employed in private organizations in Kathmandu Valley. To gather primary data, structured questionnaires were distributed utilizing the summation job factors method. 120 questionnaires were collected and subsequently employed for detailed data analysis using SPSS 25. To ensure the reliability of the collected data, the internal consistency of the construct variables was assessed using Cronbach's alpha. All computed alpha values for the constructs surpassed the threshold of 0.8, indicating a high level of consistency. Data were analyzed using mean, standard deviation, frequency, percentage, and multiple linear regression. The findings revealed a high level of job satisfaction with a mean score of 3.4. Specifically, factors such as the role of supervisors, payment/salary, working conditions, empowerment and leadership, and relationships with co-workers played significant roles in influencing job satisfaction. However, the job itself and promotion opportunities were not identified as significant factors. The coefficient of determination (R2) was calculated to be 0.872, signifying that these independent variables collectively explain a substantial 87.2% of the variation in job satisfaction among civil engineers working in private organizations in Kathmandu Valley. In light of these findings, private organizations and relevant authorities must prioritize enhancing the core responsibilities tied directly to the job, as well as providing ample opportunities for career advancement.

Published: February 2024

Radar communication systems are needed to predict weather and other military needs. One of the important parameters required for a radar communication system is an antenna with high performance and broad bandwidth that can improve the resolution. The research proposes a single patch microstrip antenna that is rectangular and has a 8 GHz resonance frequency for radar applications that have high bandwidth and performance. The antenna was developed with two dual feed lines connected to the peradiation element with the 2x1 element array technique aimed at increasing the bandwidth of the frequency. The antenna is designed using a FR-4 substrate with a tangent loss of 0.0265, a dielectric constant ( |r) = 4.3, a substrat thickness (h) = 1.6 mm. The dimensions of the rectangular single patch microstrip antenna substrata are 20x20 mm2 and 35x35 mm2 for the dual feed line antenna design. Simulation results from the antenna development showed a 159.62% increase in bandwidth compared to the original antenna design. The reflection coefficient also increased from the original design antenna, which was -16.36 dB, to -25.64 dB or an increase of 56.72%. This antenna is very suitable and recommended to be applied as a receiver antenna on radar communications systems

Published: February 2024

The large number of cases of lung disease means that doctors have difficulty in making initial diagnoses, making them prone to misdiagnoses. One type of lung disease that is included in the vulnerable category is pneumonia. Early detection of the condition of the lungs affected by bacterial pneumonia can be carried out by screening using the X-Ray examination modality, namely Digital Radiography (DR). However, in practice, the diagnosis process on Citra DR takes a long time because it requires competent medical personnel (specialists). A system is needed that can help medical personnel to speed up the process of diagnosing lung disease and get accurate results so that misdiagnosis does not occur. The aim of this research is to utilize the Spiking Neural Network (SNN) method for classifying lung disease from DR images. The system was created using MATLAB with the initial step of creating a read data program, namely reading DR image secondary data in .jpg format taken from Kaggle.com. This research uses DR image data totaling 200 images. Next, standardize the size to 50 x 50 pixels. Then segmenting the image divides the gray level histogram into two different parts of the image automatically without requiring user assistance to enter threshold values ​​for normal and pneumonia images. Then convert the image to 1 dimension and create a manual program for the training data using 50 normal images and 50 pneumonia images. Lastly, create a program to test the data using 100 normal images and 100 pneumonia images. Based on the results of data testing, a confusion matrix was obtained from 200 images with sensitivity of 87%, specificity of 69%, precision of 73.7288%, recall of 69%, and accuracy of 78%

Effect of Thermal Modification on the Density, Durability, Dimensional Stability, and Mechanical Properties of Pinus caribaea
Authors: Withanage, W.H.M.  , Amarasekera, H.S.
Published: February 2024

Pinus caribaea (Pine) is an underutilized timber species in Sri Lanka due to its low density, durability, dimensional stability, and undesirable colour. This research aims to examine the enhancements in the physical and mechanical properties of Pinewood through thermal modification (TM) and compare the properties of the TM wood with kiln-dried and untreated wood and with the properties of high-graded timbers of Tectona grandis (teak) and Koompassia malaccensi (kempas). TM is a process that involves heating wood to high temperatures (2000 C) in the absence of oxygen, which removes the moisture and creates changes in the wood at the cellular level. The effectiveness of the thermal modification on density, modulus of rupture (MOR), modulus of elasticity (MOE), moisture content, dimensional stability, durability, and colour was studied. Specific gravity of thermally modified wood was 6% higher than untreated wood, but lower than teak and kempas. MOR and MOE values were 35.75% and 46.46% respectively higher than untreated wood. Equilibrium moisture content was reduced after TM and volumetric shrinkage of TM was reduced to 2.16% and swelling under liquid water contact was reduced to 2.37%. Thermally modified timber was classified as not durable (DC 5) based on field test (EN 252, 2014) results. However, TM timber was slightly durable (DC 4) according to laboratory tests and showed better fungal resistance. The wood underwent a darkening effect as a result of thermal modification, resembling the colour of teak. The cost of TM was 13.1% higher than kiln drying. Improved dimensional stability, enhanced bending strength, and attractive appearance demonstrate the potential of thermal modification as a promising alternative for transforming P. caribaea wood into high-value raw material. TM timber finds suitable applications in indoor furniture and joinery projects. However, due to its lack of termite resistance, preservative treatment is recommended for outdoor ground contact usage.

Authors: Muthumala, C.K.  , Amarasinghe, W.V.T.D.  , Mudalige, T.
Published: February 2024

Wood anatomy is a rapid method for identifying different timber species. Shorea is a diverse genus of trees in the subfamily Dipterocarpaceae and encompasses a group of some 470 tree species that dominate much of the tropical forests of South and Southeast Asia. Many of these are valued commercially for their hardwoods. However, the anatomical identification of Shorea sp. in Sri Lanka has not been fully studied yet. Six Shorea species available in the lowland wet agroecological zone in Ratnapura District, in Sri Lanka, were selected for this study. The study was conducted in the wood Science laboratory of the State Timber Corporation, Sri Lanka. Six Shorea species, including Beraliya dun (S. disticha), Navada dun (S. stupularis), Dun (S. zeylanica), Yakahalu dun (S. trapezifolia), Yakal dun (S. astylosa) and Thiniya dun (S. congestiflora) were used to identify the variation of wood anatomical features to differentiate the species. As a reference, the Publication List of the International Association of Wood Anatomists on anatomical characteristics was used. To determine the microscopic features, six wood sections (Radial, Tangential, and Transverse sections of the wood) representing each species were employed. The anatomical characteristics of the timber were examined using Micrometrics SE Premium 4 software. According to the results, Yakahal Dun species showed the highest number of vessels and Navada represented the lowest number of vessels. The highest value for the vessel diameter showed the Thiniya species and the lowest for the Dun. Beraliya species showed the highest no of rays and the lowest number of rays showed in Yakahalu dun. A Dichotomous key was developed for the exact identification of Shorea species based on the anatomical characteristics.

Authors: Jayathilake, K.M.P.I.  , Manage, P.M.  , Idroos, F.S.
Published: February 2024

Phosphorus plays a significant role in numerous physiological and metabolic processes in plants. Soil phosphorus is immobilized due to the formation of insoluble complexes. The use of efficient phosphate-solubilizing microorganisms opens up a new prospect for better crop productivity and for greater yield performance without affecting the soil health. Phosphate-solubilizing fungi (PSF) enhance available phosphorus released from soil, which contributes to P requirement of plants. Hence, the present study was designed to evaluate the utilization of PSF as a biofertilizer. Pikovskaya's Agar medium was used to isolate fungal species from compost and open dumpsite soil. Isolated fungi were labelled as PSF-X, PSF-Y, and PSF-Z. A pot experiment was carried out to determine the effect of isolated fungal strains. The isolated fungal strain was introduced to the developed potting media which contained compost and soil at 1:1 ratio. Soya bean was selected as the experimental plant. Plant growth parameters (shoot length and root length) were measured to determine the effect of isolated fungal strains. Plant growth parameters were recorded after 21days. Fungi inoculated pots showed a significant increase in both shoot and root lengths in comparison to the control (n=9, p<0.05). Potting media consisting of PSF-X showed the best result. The highest root length (4.7±0.1 cm) and shoot length (35.8±1.2 cm) were recorded in pots inoculated with PSF-

Hence, isolated PSF-X, PSF-Y, and PSF-Z are recommended as suitable biofertilizer strains for potting medium.

Rainfall information contributes significantly to weather-related research as it can be directly applied to many theories and models such as climate change, disaster management, environmental assessments. Therefore, the availability of long-term meteorological data and their accuracy are crucial. At the same time the access to these data from different sources have their own drawbacks. For example, meteorological department of Sri Lanka is responsible of collecting rainfall data. However, their data are very expensive, and their data are not available for all desired locations. On the other hand, the freely available satellite data sources have a question of reliability of the data although no missing data are found. Thus, a comparative assessment of rainfall data was carried out from two distinct sources: meteorological department of Sri Lanka and freely available National Aeronautics and Space Administration (NASA) satellite-based data. The objective of this study was to compare and discern the distinctions in rainfall data obtained from these sources for the benefit of future usage of the data in various studies. The study was carried out in different agro-ecological Zones (wet, dry, and intermediate) of Sri Lanka for the period of 1981-2021. The stations were selected randomly to represent the zones. Identified missing values in the meteorological dataset were subsequently addressed using the mean imputation method. Statistical procedures were conducted on the non-normal rainfall data to identify similarities between the sources within individual agro-ecological zones. Results revealed that there is a statistically significant difference at 5% between the sources (NASA and meteorological measurements) in wet and intermediate zones. However, the comparison of the dry zone resulted in inconclusive decisions both at 5% and 1% significance levels. In conclusion, it is statistically advisable to use meteorological rainfall measurements over NASA data for the wet and intermediate zones.

Aquifers Recharge Potentiality Evaluation using Bivariate and Multivariate Statistical Analysis: A Case Study in Malwathu Oya River Basin
Authors: Rashmika, L.R.U.  , Ranasinghe, A.K.R.N.
Published: February 2024

An aquifer is a body of porous rock or sediment saturated with groundwater that plays a vital role in the hydrological cycle. Due to rapid population growth and urbanization, these valuable resources face threats like climate changes, pollution, and over-exploitation. Overdraft, where extraction exceeds recharge, can lead to groundwater depletion. Although Sri Lanka is not considered a water- scarce country, it faces rising water demands due to rapid population growth. Especially in dry zones, groundwater is crucial for drinking and agriculture; unauthorized agro-wells exacerbate groundwater issues. Therefore, this research aims to assess groundwater recharge potential zones in Malwathu Oya river basin using Bivariate and Multivariate statistical analysis. Comparing these techniques will lead to the precise identification of potential recharge areas. And this study primarily focuses on the implementation of GIS to find solutions for this kind of challenge without performing field investigations. Therefore, eight conditioning factors; water level, electrical conductivity, lithology, soil, slope, lineament density, drainage density and land use were selected as groundwater recharge influencing factors. The well inventory database consisted of 380 well locations and, out of these, 70% was considered as the training dataset, and the remaining 30% was taken as the testing data set. Groundwater recharge potential maps (GRP) were developed in ArcGIS 10.8, based on the results obtained from Frequency Ratio (FR), Logistic Regression (LR) and their ensemble method. For testing the accuracy of the FR model, test well locations were cross tabulated with the GRP map, and the highest well percentage was achieved in high groundwater recharge potential zone (37.39%). In the LR model, cross-tabulation results showed that 62.61% of testing wells were in the very high potential zones. The ensemble method of FR and LR revealed that 53.04% of test wells fall into the very high potential class. Hence, it can be assumed that LR predictions are more reliable than the FR model. To further validate the LR model and ensemble model, Receiver Operating Characteristics curve method was used. The Area Under the Curve (AUC) values for Success rate curve (SRC) and prediction rate curve (PRC) in LR method were 63% and 57% respectively. In ensemble method, the AUC values for SRC and PRC were 89% and 75%. These results indicate that the LR model is relatively poor estimator, whereas FR and LR ensemble method is relatively good estimator to evaluate groundwater recharge potential in Mulwathu Oya river basin.

In the process of crop management, fertilization must be practiced in an appropriate way to maintain the sustainability. Hence, the right type of fertilizer and the correct mode of application is crucial. The source and the physical nature of the fertilizer is having a significant effect on the performance of plants. In that context, liquid fertilizers are generally a convenient and effective way to enhance the nutrients availability. Hence, the present study was conducted to evaluate the effect of several liquid fertilizers on the growth performance of the popular leafy vegetable Ipomoea aquatica. Plants were established in coir grow blocks and treated with five different commonly known and available liquid fertilizers namely, Albert’s solution (T1), Compost tea (T2), Vermiwash (T3), Sanstha liquid fertilizer (T4) and Gliricidia leaf extract (T5) once a week by applying a constant volume of 100 mL. The experiment was arranged in a randomized complete block design (RCBD) inside a semi protected plant house. The growth parameters of the plants (plant height, number of leaves, leaf area, fresh weight, and dry weight) were recorded up to 60 days. One-way Analysis of Variance (ANOVA) was used for statistical comparisons. According to the results all the parameters denoted significant differences among the treatments (P<0.05), except for chlorophyll content. However, T1 denoted the highest mean values for the vegetative parameters including, plant height, number of leaves, leaf area, fresh weight, and dry weight while T3 (Vermiwash) reported the second highest values for the respective parameters. Regarding the chlorophyll content the highest mean value was recorded by T2 (Compost tea) followed by T5 (Gliricidia leaf extract). The results of the present study indicated that liquid fertilizers can be used effectively for the production of I. aquatica in coir-based media. It suggested Albert’s solution and vermiwash as high potential liquid fertilizers while vermiwash can be recognized as a nutrient supplement for organic production of Ipomoea aquatica in coir-based media.

Zoning, Land Use Management and Nature-Based Solutions in Urban Planning, Where Sri Lanka is Standing
Authors: Ranasinghe, P.R.
Published: February 2024

Urbanization rapidly changes the land use pattern in Sri Lanka. Cities are important economic centers and provide opportunities for quality of life. Zoning creates prospering urban planning environments, improves construction permit efficiency, enables agency coordination, and provides widespread participation in urban planning. A comprehensive zoning plan with environmentally conscious zoning contributes to the conservation of natural resources, enhances the ability of climate change adaptation and mitigation, fosters a greener urban environment, and ensures urban sustainability. Nature-based Solutions (NbS) are incorporated by nature; use, or mimic, natural processes to contribute to improvement in given landscapes, small or large scale. Attention to NBS has significantly increased in the recent past and is trying to mainstream NbS into a wide range of policies, and urban planning. This study aimed to explore how zoning and NbS can be incorporated in an urban setting to increase urban resilience in water-born cities. The administrative capital of Sri Lanka, Sri Jayawardhanapura-Kotte was selected due to unique inland urban wetland characteristics and vulnerability to wetland ecosystem due to rapid development in the area. Sri Jayawardhanapura-Kotte is rich with its unique landscape and is a part of Ramsar-Colombo wetlands. The Sri Jayawardhanapura-Kotte Capital City Development Plan (the Plan) 2020 and other relevant national policies were assessed in terms of zooning and application of NbS as a strategy of a sustainable and resilient city. Environmental changes and disaster risk areas were assessed (spatial and temporal changes) utilizing earth observation and GIS techniques, and secondary data were obtained from official records and reports. Sri Jayawardhanapura-Kotte covers 78% of the Greater Colombo flood retention area, and 55% of the area is suitable for flood retention. However, 40% of Colombo wetlands have been lost during the last 30 years due to urbanization. Data shows that most of the wetlands are being filled for infrastructure development, including housing, and it is critically important to conserve remaining wetlands in the area with strict regulations including zoning. The Plan has no signs of incorporating or recognizing NbS in the objectives, strategies, and actions for restoration wetlands, proper zoning system for flood mitigation. Analysed policies lack recognition or incorporation of zoning for environmental conservation and disaster risk reduction. The importance of urban areas for future cannot be underestimate and proper urban planning is a necessity in Sri Lanka for mitigate precent anthropogenic climate change impacts ranging but not limited to urban flooding to public health.

The objective of this work was to report clinical cases of Mycoplasma sp. in four Guinea Pigs (Cavia porcellus). Mycoplasma is a bacterium from the Mollicutes class that causes infections of relevance in veterinary medicine, having already been observed in several species of animals. In the present case, the main complaint brought up was related to panting and sneezing by the four animals reported. During anamnesis, it was also reported that the patients’ parents had already been tested positive for Mycoplasma sp. Upon physical examination, lung auscultation was noted with wheezing, tachypnea, and lethargy. They were sent to a hospital to stabilize their condition, where antibiotics (orally and inhaled) and local steroid anti-inflammatory drugs (inhaled) were administered. Qualitative PCR (Polymerase Chain Reaction) was performed for Mycoplasma sp., using a stool sample, in an attempt to make a diagnosis. After improving their condition, the patients were discharged to continue treatment at home. A return visit was made after 5 days for reevaluation, the animals were stable and the lungs were clear upon auscultation. The PCR confirmed the suspicion of mycoplasma, with all patients testing positive. After the diagnosis was made, a monthly protocol was carried out with Pulmotil ™ AC (tilmicosin) (10 mg/kg/SID/ 5 days/monthly/drinking water). After starting the protocol, patients improved, returning to the hospital only for follow-up appointments. The monthly use of Pulmotil™️ AC (tilmicosin) proved effective in reducing clinical signs caused by Mycoplasma sp. in the reported case, and the animals no longer presented the symptomatic form of the disease.

. Hypoadrenocorticism (HA), or Addison's disease, is an endocrine disorder uncommon in dogs, primarily occurring between 1 to 6 years of age. It can be classified according to its origin as primary, secondary, or tertiary, with its primary form being the most common. It is caused by idiopathic immune-mediated destruction of the adrenal cortex, which can result in a deficiency of mineralocorticoids and/or glucocorticoids. Clinical manifestations are nonspecific, so patients may exhibit intermittent gastrointestinal symptoms, as well as hypotension, tremors, lethargy, anorexia, and weight loss. Diagnosis is made through anamnesis, clinical signs, hematological tests, urinalysis, and abdominal ultrasound. A definitive diagnosis requires the adrenocorticotropic hormone (ACTH) stimulation test, in which dogs with HA will show results below the reference range. Treatment should be based on the patient's overall condition and hormonal supplementation, which should be tailored to each dog's specific needs. This study aims to report the case of a 1-year-old Whippet dog admitted to a 24-hour emergency veterinary hospital due to episodes of vomiting and anorexia that evolved into an Addisonian crisis. After the diagnosis of HA and the initiation of treatment with prednisolone and fludrocortisone acetate, the patient was followed-up with for 965 days, during which it experienced episodes of vomiting in stressful situations and had sodium levels at the lower limit in hematological tests.

Singapore was founded in 1819, with Protestant and Catholic missionaries working in the city from the beginning. In the first hundred years, the percentage of Christians grew to 5%, and over the next century to 19%, with most of the growth occurring at independence. State policy allowed the spread of Christianity, provided that religious figures did not participate in political life. Among the three major ethnic communities, the Chinese were the most favorably disposed to Christianity. Singapore is now a symbol of success and prosperity for the entire Southeast Asian region, international Christian conferences are held in Singapore, and the city's megachurches, which have serious organizational and financial resources, send missionaries to other countries.

Minimally invasive resection of a prominent transverse process in neurogenic thoracic outlet syndrome: new application for a primarily spinal approach. Illustrative case
Authors: Hohenhaus Marc , Lambeck Johann , Kremers Nico , Beck Jürgen , Scholz Christoph , Hubbe Ulrich
Published: February 2024

BACKGROUND

The optimal surgical approach to treat neurogenic thoracic outlet syndrome (nTOS) depends on the individual patient’s anatomy as well as the surgeon’s experience. The authors present a minimally invasive posterior approach for the resection of a prominent transverse process to reduce local muscular trauma.

OBSERVATIONS

A 19-year-old female presented with painful sensations in the right arm and severe fine-motor skill dysfunction in the right hand, each of which had been present for several years. Further examination confirmed affected C8 and T1 areas, and imaging showed an elongated C7 transverse process displacing the lower trunk of the brachial plexus. Decompression of the plexus structures by resection of the C7 transverse process was indicated, owing to persistent neurological effects. Surgery was performed using a minimally invasive posterior approach in which the nuchal soft tissue was bluntly dissected by dilatators and resection of the transverse process was done microscopically through a tubular retractor. The postoperative course showed a sufficient reduction of pain and paresthesia.

LESSONS

The authors describe a minimally invasive posterior approach for the treatment of nTOS with the aim of providing indirect relief of strain on brachial plexus structures. The advantages of this technique include a small skin incision and minor soft tissue damage.
Atypical cervical radiculopathy presenting with brachioradial pruritus: illustrative cases
Authors: Khalifeh Kareem , Le Janneinne , Musmar Basel , Maroon Joseph , Kanter Adam S , Ozgur Burak
Published: February 2024

BACKGROUND

Brachioradial pruritus (BRP) is a rare form of chronic dysesthesia characterized by persistent itching, burning, or tingling commonly involving the dorsolateral upper extremities. Although the exact pathophysiology remains unclear, the condition may be a manifestation of atypical cervical radiculopathy.

OBSERVATIONS

The authors describe two patients with BRP, a 44-year-old female and a 51-year-old male, both of whom benefited from surgical intervention for atypical cervical radiculopathy, while also highlighting their presentation, diagnostic testing, treatment, and outcomes.

LESSONS

The cases demonstrate the potential relationship between cervical spondylosis and BRP while examining the role of surgical intervention as a treatment option.
Brainstem anesthesia during awake craniotomy: illustrative case
Authors: Chen Yun , Sun Mei , Bai Hongmin , Yang Ruixin , He Huan
Published: February 2024

BACKGROUND

Awake craniotomy (AC) is performed to remove the lesions near or in eloquent areas, during which the patients are alert and without any airway instrument. Apnea is a severe complication in AC. Here, the authors describe a case of sudden apnea induced by unexpected local anesthesia of the brainstem during AC.

OBSERVATIONS

A 42-year-old male underwent AC for a large, recurrent, bilateral frontal lobe mass and experienced transient apnea and loss of brainstem reflexes during the surgery. The patient recovered spontaneous breath rhythm just a few minutes after the removal of a lidocaine cotton pledget, which was found near the patient’s midbrain. Then the patient awoke and cooperated to finish the surgery.

LESSONS

The administration of a local anesthetic subdurally in AC is common but risky. The scouring action of cerebral spinal fluid can spread those agents and cause unexpected brainstem anesthesia. A lower concentration of the anesthetic and keeping away from the cistern can make it safer.

Purpose: to develop a water intake structure for land reclamation purpose under the conditions of water withdrawal from mountainous natural water sources. Materials and methods. The paper is based on the theoretical analysis of the river hydrological and geological characteristics, which made it possible to calculate the minimum flow required for the stable operation of water intake structure and guaranteed water withdrawal during the growing seasons. The design parameters of the water intake structure were developed using the method of expert assessment with non-parametric statistics by comparing several dependent variables. Having determined the required qualities for a water intake structure, the design of a reclamation facility adapted for the conditions of the mountain and foothill zones of the North Caucasus was developed. Results. To achieve this goal, a static method for analyzing water intake structures was adapted, and statements with a factorial rating scale for expert assessment were developed. Kendall's concordance coefficient was 0.726, the data were consistent, the significance level P was less than 0.05, the differences between the factors were significant. The layer-by-layer latticed type of water intake structure has maximum efficiency. The design of a bottom-type water intake structure has been developed on the basis of the river hydrological regime and the method of water supply to the system. This type of structure demonstrates high efficiency in conditions of difficult terrain and unstable water source regimes during the growing seasons, ensuring stable water intake with minimal impact on the ecosystem. Conclusions. The proposed design of a water intake structure can be adapted to different types of water resources and their fluctuations, which makes it acceptable for mountainous areas with variable water levels in natural water sources. Minimal impact on the ecosystem is ensured by a high degree of water purification without significant changes in river channels.

Borobudur, an ancient monument renowned as a prominent tourist attraction for years, has traditionally been scrutinized through the lens of mystical logic, with prevailing discussions revolving around spiritual influences and supernatural elements. This perspective posits that every aspect of Borobudur, from its construction to its purpose, is intrinsically linked to spiritual motivations. However, a departure from this mystical logic emerges in contemporary research studies that delve into Borobudur's facets through various disciplines such as geography, geology, architecture, and astronomy. This shift aims to explore the cultural landscape of Borobudur during its construction in the eighth century from a different standpoint. In a departure from the mystical approach, this study adopts Tan Malaka's Madilog method to present a fresh perspective on Borobudur's cultural landscape. Through this alternative approach, the study unveils a compelling revelation: Borobudur's cultural landscape development aligns significantly with sustainable and economic sustainability principles. Contrary to the prevailing mystical narratives, Tan Malaka's Madilog sheds light on the pragmatic aspects of Borobudur's construction era, emphasizing a connection to broader concepts of sustainability and economic viability. This nuanced exploration broadens our understanding of Borobudur and highlights the importance of considering diverse methodological approaches to unlock the multifaceted dimension of this historical monument.
