Abstract

Syntactic foam is a lightweight, high‑strength composite consisting of a polymer matrix filled with hollow microspheres (microballoons). This study examines how the volume fraction of glass‑clad silica microballoons K15 (10–50 vol %) affects the density, porosity, and void distribution of epoxy‑bonded syntactic foams. Specimens were molded in accordance with ASTM D790, conditioned for 48 h (23 ± 2 °C; 50  ±  5 % RH), and their density was measured by the pycnometric method specified in ASTM D792. Porosity was calculated theoretically and validated by SEM–EDS imaging of fracture cross‑sections. Results show a linear decrease in density from 1.15 g cm⁻³ (0 vol %) to 0.63 g cm⁻³ (50 vol %), while porosity rises exponentially from 2.7 % to 18.4 %. Morphological analysis confirms a homogeneous microballoon dispersion up to 30 vol %, but agglomeration and interbinder voids appear above 40 vol %, leading to uncontrolled porosity. A strong negative correlation (R² = 0.96) is observed between density and effective porosity. A 30 vol % K15 loading is identified as the optimum, achieving a 28 % density reduction without a significant porosity spike. These findings provide a basis for designing sandwich cores and amphibious flotation structures that require high strength‑to‑weight ratios.

Abstract

The aim of this design is to obtain a design for the tension control system and the automatic system, which are the two mechanisms in the unwind, accompanied by an estimate of the design costs. The design process was carried out using the French method. This method is often used for new products or still has few competitors, with the advantage of being able to facilitate the selection of product concept variants efficiently when designing products that have many limitations in terms of variants. Based on the validation results, the second concept design used is a tension measurement mechanism using a load cell and speed regulation using a magnetic powder brake. The results of numerical calculations show that the maximum rotation torque value of the printed material is 13.6 Nm, the maximum speed is 628.24 rpm, and the maximum stress value measured is 206.122 N. Based on the validation results, the second concept design is a movement mechanism that uses four pneumatic cylinders to move the frame and cutter. The results of numerical calculations show that the time required to cut the material is 0.24 seconds, and the time required to return to its original position is 2.25 seconds. The amount of air required for one cutting cycle is 37.83 ×10-6 m3/s. The estimated cost of designing the overall unwind unit based on the components used is IDR. 74,873,625.

Abstract

The objectives of this research are: 1) Analyzing the effect of sterilization temperature and time on protein content in soft spiny milkfish, 2) Analyzing the effect of sterilization temperature and time on the bacterial content in soft spiny milkfish, and 3) Knowing the ideal temperature and time in the milkfish sterilization process soft spines. There are various types of diversification of processed milkfish, including processing it into presto milkfish. The shelf life of pressure-cooked milkfish can be increased by sterilization using a high-pressure pressure cooker using a retort tool. In this study, the sterilization process used a combination of temperatures of 110°C, 121°C, 130°C, and times of 10, 20, and 30 minutes. The research method uses an experimental approach. The research location is CV Sekar Tekno, Semarang. The data collection technique uses observation, which is carried out by systematically observing and recording the symptoms being investigated. Data analysis techniques use descriptive statistics and analysis of variance/ANOVA. The results of the research showed that the effect of temperature and time on the sterilization process of soft spiny milkfish did not have a significant effect on the protein content of soft spiny milkfish. Although the protein content of soft spiny milkfish experienced changes up and down during the sterilization process, the protein content did not decrease significantly. The effect of high temperature in the sterilization process of soft spiny milkfish has a significant effect on the number of bacteria present in soft spiny milkfish after the sterilization process. This is indicated by the phenomenon of a constant decrease/value of bacterial content as shown in the following data: temperature 110°C is 148.44 CFU/g, temperature 121°C is 86.78 CFU/g, and temperature 130°C is 25.44 CFU/g. On the other hand, the effect of long sterilization time on the bacterial content of soft spiny milkfish tends to show an up-and-down phenomenon. This is indicated by an increasing trend in the number of bacteria at 30 minutes, which was 125 CFU/g. This phenomenon is caused by a leak in the retort pack used for soft spiny milkfish and other causes that are not yet known for certain in this process. Based on the results of the effect of temperature and time on protein levels and bacterial content, it shows that a temperature of 130°C has a high protein content of 16.6% with the lowest bacterial content, namely 45 CFU/g. At 20 minutes, it had a high protein content of 14.296% with the lowest bacterial content, namely 32.67 CFU/g. So the ideal temperature and time for the sterilization process of soft spiny milkfish is 130°C and 20 minutes

Abstract

Autodesk Inventor software learning in manufacturing drawing subjects in vocational schools requires the support of interactive visual-based media to make complex technical materials easier for students to understand. The weakness of conventional methods in conveying this concept requires a breakthrough through the use of modern learning technology. This study focuses on evaluating the effectiveness of using PowerPoint-based multimedia to improve students' mastery of Autodesk Inventor. The research design used the purposive sampling method with pre-test and post-test models in two groups involving 60 students in grade XI of Mechanical Engineering at SMK Negeri 5 Semarang. The experimental group made use of interactive PowerPoint media, while the control group continued to use traditional methods. The results showed a significant increase in the experimental group with a p< value of 0.05 and an N-Gain value of 0.499 much higher than the control group with only 0.148. Thus, the use of interactive PowerPoint has proven to be effective in strengthening students' understanding of assembly engineering materials in a more interesting, flexible, and appropriate way for learning needs.
