Published: November 2023

Bus Rapid Transit (BRT) in modern times has become a prevalent issue in various parts of the world. The reasons are passenger appeal and expandability, high performance, and quality, as well as its buildability quickly, step-by-step, and ergonomics. With all this flexibility, BRT can provide high-quality transit performance over a wide range of geographic areas outside of dedicated lanes. This paper aims to find out the passenger occupancy phenomena of BRT in the main corridors in Jakarta. The hope is that BRT operators and regulators can optimally provide services for users after knowing the growing trend. The method used is to know the trend based on the graph of the number of BRT users in 2019-2020. The study results concluded trend of annual passengers has decreased by more than 50%, which is thought to be due to the COVID-19 Pandemic. While the monthly passenger trend will increase by 14% in November and December, this is a due accumulation of activities at the end of the year. Furthermore, the daily passenger trend is dominated by weekdays on Mondays, with the number of passengers 28% above the daily average

Authors: Firmansyah Fikri , Rifai Andri Irfan , Taufik Mohamad
Published: November 2023

Roundabouts with traffic signals at the Kadipaten intersection are one of the centers of activity in this area, with traditional markets, shops, and terminals. The rapid development in this area has caused the traffic volume at the intersection to increase, resulting in various traffic problems, including congestion and chaos. The Traffic Signaling Tool's function has yet to provide a solution to congestion and chaos, especially during rush hour. Especially with the roundabout in the middle of the intersection, which adds to the obstacle. The research method is a qualitative method, which is carried out directly or through surveys in the field that refer to IHCM 1997. This research aims to analyze the performance of traffic that occurs at the signalized roundabouts at the Kadipaten intersection. The study results show that the Duchy intersection's performance is less than optimal when using roundabouts. Interchange performance will be more optimal if the roundabout is eliminated. The decrease in intersection performance is indicated by the higher degree of saturation (DS) and delay (DT). Degree saturation at the Duchy of Interchange is currently 1.54, with the highest delay time reaching 392 seconds.

Commuter Railways (KRL) is one of Indonesia's modes of mass transportation, especially in the Jabodetabek area. The existence of KRL makes it easier for people to travel, so it is necessary to emphasize service quality in following its users' wishes. This paper aims to increase KRL user satisfaction with KRL services and schedules. Questionnaires were distributed to 100 respondents at the station and on the KRL. The data analysis method used is the Importance Performance Analysis method which is processed using Microsoft Excel. From the analysis results, nine variables are considered essential but still need to meet the expectations of KRL users, so they become the top priority. Then, seven variables are considered essential and have met expectations, so these variables must be improved. Based on the research results on the level of passenger interest in the Citayam-Tebet KRL route, an average value of 4.60 is obtained with an average level of performance of 4.11, which means that the variable is still not as expected and does not meet the satisfaction of KRL passengers.

Published: November 2023

In today's globalized world, much software is developed to make work easier to implement. This software is demonstrated using AutoCAD Civil 3D® to demonstrate how geometric road design can be completed briefly. In this case, the purpose of geometric planning is to evaluate the effectiveness of manual geometric planning using AutoCAD Civil 3D®. This journal's geometric road planning implements qualitative methods. The geometric planning of the road that became the subject of this journal's research is located on Jalan Kertawangunan - Kadugede, with a road plan length of 9.3 km as an additional alternative to Kuningan Regency's new outer ring road. The calculation of horizontal alignment required the minimum bend (Rmin) and transition arch (Ls) values. Therefore, it is necessary to plan the assembly ahead of time before planning the corridor. The corridor's function is to determine the location of cut and fill based on road planning. As a result, planning a path with AutoCAD Civil 3D® is more effective and efficient, and it can retrieve the necessary data quickly. There are four points of interest with different types of curves in road traffic planning. The plan speed (Vr) was set to 60 km/h, the maximum superelevation slope (e-maks) was set to 0.08, and the transverse friction coefficient (f) was set to 0.153. The average excavation volume obtained from this planning is approximately 1,900,000 m3.

At present, global warming increment and petroleum reserve depletion have been a major threat to the environment. These occur due to various human activities. Construction industry contributes 40 % for the global carbon emission. From that 10% is contributed from the manufacture of cement and the rest is contributed by the other requirements in the construction industry. Therefore, scientists are now more focused to involve bio-based products to minimize the emission of carbon. This resulted in, paying more attention towards the natural composite materials that can be used instead of artificial materials. Scientists are eager to find natural materials which are locally available. The structures built today, does not survive the entire service life of the structure. This is due to corrosion of steel, especially in coastal areas. So, in order to overcome this, use of a natural material which can provide the same tensile strength can be used. Over the past few decades engineering materials like composites, plastics, ceramics has dominated the engineering industry. There are new polymer materials introduced such as glass fiber, carbon fiber and aramid but they are not eco-friendly. The main problem associated with these is the high production cost. Therefore, new composites which are environmentally friendly should be found in order to replace other materials. Even though there has been much research published on different natural fiber composite materials, here an attempt has been made to use coir to produce reinforcement bars in order to combat corrosion Keywords: coir, composite, corrosion, petroleum, fiber glass, aramid

Published: November 2023

Microplastics, which can enter aquatic environments through various sources, are small plastic pieces that are less than 5 mm in length. There are two types: primary and secondary microplastics. Sri Lanka has limited studies on microplastics in inland water bodies, so this research aims to quantify the levels of microplastic pollution in Colombo's surface waters in a spatiotemporal manner. Samples were taken from Beira Lake, Dutch canal network, Talangama canal, in wet and dry seasons. Microplastic concentrations were determined using NOAA guidelines and an optical microscope. Statistical analysis was performed using IBM SPSS version 21, including One-way Anova and Pearson correlations to identify significant differences and correlations. The study found that Dutch Canal had the highest average microplastic concentration of 12.7 mg/L during the wet season, and the lowest of 4.2 mg/L during the dry season. Both Dutch Canal and Talangama canal showed significantly higher microplastic concentrations during the wet season than the dry season, while the opposite was found in Beira Lake. The statistical analysis showed significant differences between microplastic concentrations in wet and dry seasons in all three water bodies. The microplastic levels in Beira Lake were higher on the surface water during the dry season (4.32 mg/L) and wet season (13.77 mg/L) compared to point sources (4.05 mg/L and 11.68 mg/L, respectively). Furthermore, Dutch canal's point sources showed higher during the dry season (8.47 mg/L) than the wet season (11.51 mg/L) and concentration of microplastics on the surface water was higher during the wet season (5.73 mg/L) than the dry season (7.16 mg/L). Talangama canal had similar patterns to Beira Lake. The study found microplastic contamination in urban and semi-urban surface waters at levels comparable to some industrialized countries, highlighting a concerning issue.

Cost overruns are a significant issue in the construction industry, particularly from the standpoint of clients. Many studies have been interested in the unpredictable situations that lead to cost overruns, with the primary goal of pinpointing the precise causative factors. There is a knowledge gap about whether cost overruns could be prevented through effective decision-making at a project’s earliest phases. Therefore, the aim of this research was to critically review if the impact of the project duration decision taken at the bidding process could lead to cost overruns of Sri Lankan building projects, and to provide recommendations of preventive measures to be taken. Deductive research approach and qualitative analysis was used to achieve the four main objectives set for this study. The literature review was able to identify the significant causative factors for cost overrun in the construction industry. The analysis of data collected through questionnaire survey and semi-structured interviews revealed that there are several causative factors for cost overrun, that stem from the project duration being excessive or inadequate : Claims and disputes, inadequate planning and scheduling, unrealistic work schedule, expense due to completion delay and extension of time, and difficulty in predicting the future. This study was able to identify that there is a relationship between project duration decision and cost overrun, where if the project duration decided at the bidding process is excessive or inadequate, it will be causative of cost overruns. Finally, this study has provided preventive measures to avoid cost overrun at the bidding process when deciding the project duration.

Assessing the impact of seed priming by nanomaterials on stevia germination and biochemical attributes under drought stress
Authors: Safaeipour Mahla , Kalat Mohsen , Shahverdi Mehdi
Published: November 2023

Seed priming with nanocompounds can potentially enhance seed germina- tion and tolerance to environmental stress. The study examined the effects of drought stress induced by PEG-6000 at various levels (0, −0.3, −0.6, and −0.9 MPa) and seed priming with different nano-compounds (zinc oxide, titanium oxide, or silicon) on the germination, growth, and biochemical and physio- logical characteristics of stevia. The results showed that drought stress had a negative impact on most seed germination and growth parameters, while seed priming with zinc oxide nanoparticles had the highest positive impact. Different seed priming treatments produced varying outcomes. Drought stress and seed priming also significantly affected total chlorophyll content, chlorophyll a and b, and antioxidant enzyme activity (catalase and peroxi- dase). Under severe drought stress, all the three seed priming combinations significantly increased total chlorophyll content. Increasing the concentra- tion of PEG-6000 in the seedling growth medium increased catalase activity. Non-primed seeds and seeds primed with zinc oxide under severe drought stress had the highest peroxidase enzyme activity. The Pearson correlation analysis revealed significant correlations among the measured traits. Lastly, the stepwise regression analysis identified catalase and peroxidase activities as the most influential traits related to stevia seed germination percentage. Seed priming with zinc oxide nanoparticles can enhance stevia seed germina- tion and growth, particularly under drought stress, by adjusting antioxidant enzyme activity and increasing photosynthetic pigment content. Moreover, as a practical outcome, the utilization of priming can serve as an applicable approach in the production of seedlings for this plant.

Application of appropriate doses of macro and micronutrients is pre-requisite for maximizing growth and yield of crops. The present study was conducted at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh during the period from October 2022 to February 2023 to assess the effects of different doses of nitrogen (N) and zinc (Zn) on growth and yield of cabbage. The two-factor experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The first factor was nitrogen having four doses of N, such as N0 = 0 kg/ha, N1 = 100 kg/ha, N2 = 150 kg/ha and N3 = 200 kg/ha and the second factor was Zn having four doses, namely Zn0 = 0 kg/ha, Zn1= 1.5 kg/ha, Zn2 = 2.0 kg/ha, Zn3 = 2.5 kg/ha. Significant variations were noted due to the application of different doses of N and Zn fertilizers in respect of all growth and yield traits studied. Application of N at 200 kg/ha contributed the best outcomes on plant height (32.72 cm), number of leaves per plant (47.86), gross yield per hectare (69.99 tons), marketable yield per hectare (45.98 tons) and the lowest yield per hectare (64.52 tons), marketable yield per hectare (38.37 tons) produced from control treatment. The highest level of zinc Zn3 (2.5 kg/ha) produced the best results on plant height (32.30 cm), number of leaves (48.26) per plant, gross yield per hectare (78.02 tons), marketable yield per hectare (61.62 tons) and the lowest gross yield per hectare (59.17 tons), marketable yield per hectare (29.40 tons) produced from control treatment. The maximum doses of nitrogen and zinc (200 kg/ha and 2.5 kg/ha), respectively showed the best performance on plant height (33.32 cm), number of leaves (49.53) per plant, gross yield per hectare (81.15 tons), marketable yield per hectare (65.78 tons) and the lowest gross yield per hectare (55.41 tons) and marketable yield per hectare (27.28 tons) were obtained from the control treatment. The results of this investigation revealed that application of nitrogen (N) and zinc (Zn) enhanced the affects the growth and yield of cabbage.

Authors: Etli Ibrahim , May Hasan , Cicek Engin , Celik Cihan , Mohamed Abdullahi
Published: November 2023

The plantar muscle is fusiform, attaching to the calcaneus, starting behind the knee. Plantaris muscle formation has been reported in humans at a rate approaching 90%. It is frequently preferred for tendon grafting and tendon transfer in hand surgery and Achilles tendon injuries. In this study, our goal is to investigate the frequency of the presence of the plantar muscle in the Somali population. We retrospectively analyzed 607 knee MRI scans performed at Recep Tayyip Erdoğan Training and Research Hospital in Mogadishu between January 2019 and March 2022. The clinical and demographic characteristics of the patients were recorded. Patients with muscle trauma and previous surgery involving muscles, proximal tibia fracture surgery, and soft tissue tumors were dropped out of the study. 469 (77.3%) of these patients were male and 138 (22.7%) were female.182 (72%) of the male patients with right MRI saw plantaris while 68 (28%) did not. While plantaris was seen in 183 (83.5%) of the male patients who underwent left-sided MRI, plantaris was not seen in 30 (16.5%). Plantaris was seen in 62 (79.5%) of the female patients who had right-sided MRI, while plantaris was not seen in 16 (20.5%). Left plantar was present in 55 (91.7%) and absent in 5 (8.3%) female patients who underwent left-sided MRI. Since the plantaris muscle is used as a tendon graft, pre-op evaluation of its presence is important in terms of surgery and can change the surgical procedure. The presence of the plantar tendon can be revealed by using knee MRI in the Somali population living in the African continent.
Estimation of change in forest variables using synthetic aperture radar
Authors: Huuva Ivan
Published: November 2023

Large scale mapping of changes in forest variables is needed for both environmental monitoring, planning of climate actions and sustainable forest management. Remote sensing can be used in conjunction with field data to produce wall-to-wall estimates that are practically impossible to produce using traditional field surveys. Synthetic aperture radar (SAR) can observe the forest independent of sunlight, clouds, snow, or rain, providing reliable high frequency coverage. Its wavelength determines the interaction with the forest, where longer wavelengths interact with larger structures of the trees, and shorter wavelengths interact mainly with the top part of the canopy, meaning that it can be chosen to fit specific applications. This thesis contains five studies conducted on the Remningstorp test site in southern Sweden. Studies I – III predicted above ground biomass (AGB) change using long wavelength polarimetric P- (in I) and L-band (in I – III) SAR data. The differences between the bands were small in terms of prediction quality, and the HV polarization, just as for AGB state prediction, was the polarization channel most correlated with AGB change. A moisture correction for L-band data was proposed and evaluated, and it was found that certain polarimetric measures were better for predicting AGB change than all of the polarization channels together. Study IV assessed the detectability of silvicultural treatments in short wavelength TanDEM-X interferometric phase heights. In line with earlier studies, only clear cuts were unambiguously distinguishable. Study V predicted site index and stand age by fitting height development curves to time series of TanDEM-X data. Site index and age were unbiasedly predicted for untreated plots, and the RMSE would likely decrease with longer time series. When stand age was known, SI was predicted with an RMSE comparable to that of the field based measurements. In conclusion, this thesis underscores SAR data's potential for generalizable methods for estimation of forest variable changes.

Vitamin E – Recommended and Actual Intake
Authors: Sabolová Monika , Fišnar Jakub , Réblová Zuzana
Published: November 2023

Vitamin E has only relatively mild manifestations of hypovitaminosis in humans, which, moreover, are not, in most cases, caused by insufficient content of tocopherols in the diet. Thus, the fact that the actual intake of vitamin E is (worldwide) insufficient in the majority of the population is likely to escape the attention of nutrition policy. This review summarizes current information on the recommended and actual intake of vitamin E and on the risks and possible benefits associated with insufficient or increased intake.
Methodology for Determination of the Total Amount of Phenolic Substances, Flavonoids and Antioxidant Capacity of Plant Samples using Combined Extraction
Authors: Berková Veronika , Štěpánková Lenka , Čičmanec Petr , Frejlichová Lucie , Berka Miroslav
Published: November 2023

Although multiple methodologies are used to determine antioxidant parameters in plants, most studies use separate extractions for each type of the determination. The aim of this work was to specify detailed methodology able to analyse the total amount of phenolic and flavonoid compounds and total antioxidant capacity from one sample using a microtitration plate format to minimize the sample consumption. In addition to that, the described extraction procedure and the decreased sample consumption enable one to make complementary analyses and a closer characterization of the composition of plant samples. The extract can be used for subsequent targeted analyses, which was demonstrated by the determination of selected flavonoids using GC-MS analysis, which confirmed the results of spectrophotometry. The described combined extraction of plant samples facilitates complex analyses, reduces the amount of starting material and enables the subsequent analysis of biomolecules.

Driving Innovation: Analyzing Mobile Ridesharing App Interfaces and Moving Toward Community-Based User Experience (CBX)
Authors: Allen Laura L. , Johnson Gavin P.
Published: November 2023

Purpose: Our article interrogates mobile ridesharing apps as sites where digital interfaces, cultural practices, and rhetorical discourses intersect. We establish counter- histories of mobile ridesharing apps and conduct a critical interface analysis of select apps to demonstrate
how innovative interfaces imagine a universal user while culturally specific apps make space for community-based user experience (CBX). Method: This article brings together Haas' digital cultural rhetorics (DCR) framework with Brock's critical technocultural discourse analysis
(CTDA) to zoom in on the cultural ideologies, form, and function of mobile ridesharing apps. Results: Our analysis highlights how developers of culturally specific apps inscribe and promote an ethos of community for users marginalized by Western ideologies regarding race, gender, and
sexuality. We show that, despite working in prescribed programming and coding structures, these app developers take advantage of forms and functions to amplify their cultural significance. Conclusion: Rhetoric, technical communication, and UX researchers and practitioners should look
to culturally specific mobile ridesharing apps as exemplars for designing technologies that center and acknowledge multiply-marginalized communities and their DCR practices. We insist CBX be part of interface design.
