Abstract

Cytokinins are growth regulators that play a crucial role in cell division and shoot growth. Thidiazuron, a potent cytokinin, was the focus of our research. The research aimed to determine the effect of several concentrations of Thidiazuron on the protocorm growth of Grammatophyllum stapeliiflorum and to identify the best concentration of Thidiazuron (mg/L) for the protocorm growth of G. stapeliflorum orchids in vitro. The research was conducted from January until March 2022 at the Plant Physiology Laboratory, Universitas Andalas, Padang. The research used a Completely Randomized Design (CRD) with 5 treatments and 5 replications. Several concentrations of Thidiazuron were added to MS media with various concentrations: 0 mg L-1 (A), 0.50 mg L-1 (B), 1 mg L-1  (C), 1.50 mg L-1(D), and 2 mg L-1  (E). The parameters in this research were the percentage of life explants, day of shoot appearance, number of shoots, shoot length, number of leaves, number of roots, and root length. The results showed that Thidiazuron significantly affected the protocorm growth of the G. stapeliiflorum orchid compared to the control treatment. Notably, 2 mg L-1  Thidiazuron emerged as the best concentration for all growth parameters of protocorm G. stapeliiflorum, a finding that could significantly impact our understanding of orchid cultivation and plant physiology.

Abstract

The tofu industry produces high protein food but produces wastewater with high organic matter and ammonia which is the result of protein breakdown in soybean seeds during the extraction process. Small and Medium Enterprises (SMEs) sometimes neglect waste treatment due to limited resources. Indonesian regulations stipulate special quality standards for wastewater in the Regulation of the Minister of Environment of the Republic of Indonesia No. 5 of 2014 concerning Wastewater Quality Standards for Soybean Processing Businesses and/or Activities. Indicators of organic matter pollution are characterized by the parameters BOD 150 mg/l, COD 300 mg/l, TSS 200 mg/l, and pH 5-9. Meanwhile, tofu industrial wastewater without special treatment can exceed the quality standard with BOD levels of 5.000-10.000 mg/l and COD levels of 7.000-12,000 mg/l. To overcome this problem apart from using activated sludge, researchers are exploring the use of Aerobic Granular Sludge (AGS) technology. AGS involves aggregate microorganisms in granules to treat wastewater efficiently. This increases treatment efficiency, reduces space requirements, and handles high organic loads effectively. Although aerobic granular technology is promising, research is still ongoing to better understand its characteristics and optimize applications in various industries and environmental conditions. This study aims to explore the potential application of Aerobic Granular Sludge (AGS) technology in treating tofu industrial wastewater with high organic matter content and significant ammonia content so that it meets permitted quality standards.

Abstract

Science learning in the independent curriculum seems to still stand alone, is oriented cognitive learning outcomes, does not relate to social issues, and is not yet oriented towards scientific literacy. In the field, there is no yet available natural and social science learning model framework that structurally involved social, ethical and moral issues, through a Socio Scientific Issues (SSI) approach that is applicable to educational practitioners. This research aims to produce a framework for a natural and social science (IPAS) learning model based on Socio Scientific Issues (SSI) approach to strengthen students' scientific literacy in elementary school. This Design Based Research (DBR) was carried out through stages problem identification and analysis; design; testing and evaluation); and reflection. This research involved teachers and students of grade IV Islamic elementary schools in Kartasura, Sukoharjo, were taken using purposive sampling. The model validity test was carried out by experts in the fields of learning models, content and language. The resulting IPAS learning model based on Socio Scientific Issues (SSI) approach framework has a validity of 99.2% (very valid) and a learning tool of 96.5% (very valid). This model is very practical to implement (score 86%), and is quite effective in strengthening the scientific literacy of elementary school students. This model is suitable for application at other elementary school levels in a wider scope, with careful planning in terms of infrastructure and time management.

Abstract

In aircraft structures, composite plate joints often present significant challenges. Mechanical fastenings such as pins, bolts, or rivets require holes to be drilled in the plates, which reduces the strength of the laminate due to stress concentrations around the hole edges. These joints frequently become sources of structural failure in aircraft. Therefore, the design of composite plate joints is crucial to maintain structural integrity. Adhesive joints offer several advantages over mechanical joints, including the ability to join two different materials, more uniform stress distribution along the joint, and reduced weight since no bolts or rivets are needed. The most common adhesive joint design is the Single Lap Joint (SLJ), which is popular due to its simple geometry and high structural efficiency. However, the main drawback of the SLJ is load eccentricity, which leads to secondary bending and undesirable normal stresses along the adhesive edges. The hypothesis of this study is that SLJ conditions with optimal shear strength can be achieved through the right combination of adhesive type, bond surface preparation, and joint configuration. This study analyzes the influence of various adhesive materials, joint designs, and manufacturing methods using numerical modeling methods, validated with analytical approaches and ASTM standard testing. Numerical modeling is conducted using the finite element method with a cohesive zone model (CZM) approach to examine stress distribution in various cases, such as the impact of geometry, adhesive thickness, and joint length. The normal and shear stress distribution along the joint is found to significantly affect the strength of the SLJ, highlighting the importance of careful design and material selection in these applications.

Abstract

The disposal of industrial sludge from Water Treatment Plants (WTP) poses environmental risks, particularly groundwater pollution. One solution is reusing this sludge in brick production, as clay use is unsustainable and may lead to shortages. This research investigates innovations in brick making, specifically using WTP sludge and the Microbially Induced Calcite Precipitation (MICP) technique with Bacillus huizhouensis to enhance brick strength. The MICP method produces calcium carbonate (CaCO₃) naturally, reinforcing bricks without harmful burning. After 50 days, compressive tests showed that bio-bricks with 15% WTP sludge and 25% bacteria achieved the highest strength of 3.79 MPa, compared to 1.49 MPa for mud bricks with only sludge. However, bio-bricks with 6% bacteria and 15% sludge reached only 1.74 MPa, with all values below the SNI 15-2094-2000 standard of 5 MPa.
