Published: December 2024

Objective: To enhance the safety, simplicity, and efficacy of non-invasive prenatal paternity testing, we developed a method based on multiplex PCR targeted capture sequencing technology utilizing single nucleotide polymorphisms (SNPs) as genetic markers.

Method: We screened 627 SNPs from public databases and literature based on specific criteria and population genetic data from 100 unrelated individuals. A total of 15 peripheral blood samples were collected from pregnant women and the suspected father. Paternal alleles were detected and analyzed in the plasma cell-free DNA (cfDNA) of pregnant women, fetal SNP genotypes were obtained, and the combined paternity index (CPI) was calculated for paternity testing.

Results: Biological fathers were accurately determined in all cases, with CPI values ranging from 1.05 × 1014 to 2.03 × 1034, consistent with results obtained using polymerase chain reaction-capillary electrophoresis (PCR-CE) with short tandem repeats. Significant differences in CPI between unrelated males and biological fathers allowed for straightforward exclusion. Even cfDNA from maternal plasma as early as five gestational weeks enabled accurate paternity determination.

Conclusion: This novel approach demonstrates significant improvements by reducing the number of SNPs, streamlining the research procedure, and lowering costs, yielding substantial advancements in non-invasive prenatal paternity testing.

Published: December 2024

Critical thinking is a skill needed to solve problems in the 21st century. However, the critical thinking skills of Indonesian students are still considered low, as confirmed by PISA research results. This low critical thinking ability is due to students' limited understanding of factual and conceptual information when solving problems. One learning model that can serve as an alternative to improving students' critical thinking skills is the Inquiry model with a STEM approach. In this model, students are actively engaged in learning, as the process focuses on them. Additionally, the STEM approach enhances students' critical thinking abilities because it integrates various fields of knowledge, enabling students to think from multiple perspectives and become accustomed to critical thinking. The purpose of this research was to determine the effect of the Inquiry learning model with a STEM approach on students' critical thinking skills. This quantitative research was conducted at Mts 1 Jember during the even semester of the 2024/2025 academic year. The sample included class VIII B as the experimental group and class VIII D as the control group, selected through purposive sampling. Data collection techniques involved tests as the primary instrument, with supporting instruments such as observation, interviews, and documentation. Data analysis was conducted using the Independent Sample t-test, which showed a significance value (2-tailed) of 0.000 < 0.05. The results indicated a moderate increase in students' critical thinking skills, with a score of 0.68. From this analysis, it can be concluded that the use of the Inquiry learning model with a STEM approach has a significant positive impact on improving students' critical thinking skills.

Published: December 2024

This article presents a conceptual study (literature review) of several research results focused on developing modern physics learning tools. The research subject comprises ten articles from national and international journal databases within the last ten years (2014-2024). The results of the conceptual study show that several studies have developed teaching materials for Modern Physics lectures, but they still have limitations. These limitations are that the scope of the modern physics material developed has yet to be efficient for students to use online; the teaching materials developed in the form of applications are quite heavy when opened using a smartphone and require quite a large storage space capacity. The use of multimedia in physics learning in Indonesia is quite rapid, easy to present material, efficient to use, and supported by the latest applications to produce teaching materials that can insert text, images, videos, and interactive quizzes. The conclusion obtained from this conceptual study research is that the development of modern physics learning tools has been proven to improve the quality of learning, and there has yet to be any development of modern physics teaching materials based on interactive multimedia. The results of this conceptual study became one of the bases for developing teaching materials for modern physics based on interactive flipbooks.Implications of research on curriculum development and modern physics improving students' critical thinking skills. This approach is expected to increase students' interest in studying modern physics.

The phenomenon of soil scour is influenced by several factors, namely, continuous rainfall, slope, and soil movement. This causes landslides, especially on slope surfaces. The use of vegetation can be used as an effort to overcome shallow landslides on a slope.This study aims to determine the characteristics of the soil, the effect of plant roots on the shear strength of the soil by using a direct shear test tool and to determine the safety value on the slopes by using Geo5 application analysis. The types of plant roots used in this study were Paitan grassroots, Teki grassroots, Setaria grassroots, Gajah grassroots and Alang-Alang grassroots.From the results of the direct shear test, the shear strength value of the soil and Paitan grassroots was 101.433 kg/cm2, the soil with Teki grassroots was 99.392 kg/cm2, the soil with Setaria grassroots2, Alang-Alang grass is 123,730 kg/cm2 and the highest value is found in the soil and Gajah grassroots which is 105,7039 kg/cm2. With the characteristic form of fibrous roots and able to grow to very deep depths, the roots of these plants can have a great impact on soil shear resistance. The greater the diameter and root content in the soil, the greater the shear resistance. The presence of plant roots has proven to be helpful in increasing the holding moment even after erosion has occurred. It can be said that the presence of plant roots on slopes is one of the potential solutions as an effective, economical, and environmentally friendly method. Keywords: shear strength, retaining moment, safety value, plant roots, erosion

Published: December 2024

Currently, numerical methods have been widely used to analyze the case of deep foundations, both determining the bearing capacity and settlement due to loads that occur on the foundation. This method has been used to obtain friction bearing capacity and end bearing capacity to obtain the adhesion factor in soft soil.The purpose of this final project was to generate the respective values of the friction bearing and the end resistance of the pile cap on a loading test 200% of the design load through finite element simulation of FEM (Finite Element Method) using the Plaxis 2D program. This research began by collecting data from the N-SPT and CPT soil investigations, loading test data, and pile specification data. The soil investigation data were correlated into soil parameters (E, v’, c, dan φ) which were required by Mohr-Coloumb modeling on Plaxis 2D to produce end bearing and friction bearing capacities that were in accordance with the loading test results.The results of the loading test 200% of the design load carried out on the pile of TP No.101, As.Q-5 resulted in a friction bearing capacity of 15 meters of piles is 95.98 tons, and an end bearing capacity is 4.08 tons. And then, the TP No.58F-2E pile resulted in a friction bearing capacity of 15 meters long piles is 91.96 tons, and an end bearing capacity is 8.04 tons. The results shows that at a load of 200% of the design load carried out on the piles it can still be well supported by the friction bearing capacity of the pile cap, so that the end bearing capacity still receives a much less load than the load received by the friction bearing capacity. Keywords: bearing capacity, pile cap, loading test, numerical methods

Published: December 2024

Steel materials have a superiority in terms of strength, rigidity, and ductility compared to other structural materials, in addition  to that  with the material being detailed and  high specific strength can produce a lighter structure.  In this study,  a redesign of the Banjarbaru City PUPR office building with a steel structure was carried out, this 2 (two) floor building with size  of  24 x 36 m2 was previously designed using a reinforced concrete structure.  The designed structure falls into the category of B seismic design and is designed with a common moment-bearing frame system (SRPMB). The design results are for the roof structure used double elbow profiles ⊥50.50.5, ⊥45.45.4, and ⊥30.30.3, for floor plates using floordeck with a thickness of 0.75 with a plate thickness of 110 mm and wire mesh reinforcement M8 – 175. For the child beam and the main beam successively use the WF 250×125×6×9 and WF 300 x 150 x 5.5 x 8 profiles, where the beams are designed as composite beams. While the column uses the H150x 150x10x15 profile. Rigid Connection is carried out at the connection of the moment-retaining beams while simple connection is carried out at the beam-beam connection. For the foundation used pile foundations with dimensions of 25x25 cm are staked to a depth of 6 m. The results of the structure comparison obtained that the effective weight of the steel structure is almost 50% lighter than the concrete structure, so that the basic shear force, displacement, and deviation between floors (story drift) that occurs are smaller. For the comparison of the foundation used with the same dimensions and depth in the steel structure, 2 poles are needed, while for the concrete structure it takes 4 pieces to withstand the load of the upper structure. Keywords: Steel Structure, Rigid Connection, Simple Connection.

Drainage in Banjarbaru City is generally good, but inundation rarely occurs. However, in certain areas, periodic inundation occurs namely inundation for less than 6 (six) months, one of which is in the Landasan Ulin District, which is a transition from swampland to residential use. The research location is the existing drainage canal which is located on several roads of the Hercules complex, Landasan Ulin Village. In general, the drainage channels in the Hercules complex are stone masonry. Improper maintenance causes sedimentation, which impacts drainage channel services. This final project aims to re-evaluate the drainage channels in the residential area of the Hercules complex in Banjarbaru City based on the network system in the residential environment. The analytical method is divided into two. The first is hydrological analysis and hydraulic analysis.From the results of hydrological and hydraulic analysis and also a comparison of calculations with the existing drainage network system that has been developed, it can be seen from the runoff discharge in the existing channel (Qex) then compared with the calculation of the design flood discharge (Qr) that the cross-sectional dimensions of Box Culvert (60 x 80 x 100), U-Ditch 1 (60 x 75 x 100), U-Ditch 2 (60 x 90 x 100) and U-Ditch cover 5 cm thick is sufficient to accommodate flood discharge two years, five years, ten years, 15 year and 20-year anniversary plans. Keywords: Drainage Network System, Design Flood Discharge, Rainfall Intensity, Runoff Discharge
