Abstract

Industry 4.0 is supported by nine foundational pillars, including Big Data and Analytics, Autonomous Robots, Simulation, Horizontal and Vertical System Integration, the Industrial Internet of Things (IIoT), Augmented Reality, Cloud Computing, Additive Manufacturing, and Cybersecurity. This study focuses on horizontal and vertical system integration, which enables seamless information flow across departments, suppliers, and customers through smart systems and IoT devices. One important tool in supporting industrial integration is Computer Aided Design (CAD), which plays a key role in product design and the generation of blueprints that bridge design and manufacturing functions. Most widely used CAD software such as AutoCAD, SolidWorks, Inventor, and CATIA are commercial and come with high licensing costs. At Samudra University, Autodesk Inventor Student Version was previously utilized for educational purposes; however, due to its feature limitations and temporary license, an alternative was sought. In collaboration with the Mechanical Engineering Department, FreeCAD was explored as an Open Source solution. This research aims to identify a free and open-source CAD software that offers features comparable to commercial CAD tools and can be further developed without licensing constraints. The methodology involves collecting various Open Source CAD applications, establishing evaluation criteria, testing core functionalities, and selecting the most suitable application to support academic and industrial design needs.

Abstract

Aceh Province is experiencing rapid changes in infrastructure along with population growth and globalization and urbanization. This development and growth has led to a significant increase in the construction of high-rise buildings in urban areas. In multi-storey buildings, the use of materials that have a low albedo against solar radiation, so that a lot of radiation is absorbed and stored in the form of heat in the building so that it can increase the temperature of the building up to 12 °C. The absence of heat absorbers such as green plants around the building affects the thermal comfort of building occupants. Thermal comfort can be measured using various parameters, one of which is the Temperature Humidity Index (THI). The use of green plants of the type of Sansevieria Ttrifasciata which is used as a building envelope for 7 days on the 2nd floor of the Samudra University Laboratory building to measure the temperature difference after being absorbed first by the (Sansevieria Ttrifasciata) in the photosynthesis process. The results show that the THI thermal comfort index is reached at 25°C to 26°C with the conditions shown based on the ASHRAE 55 standard is thermally comfortable.

Abstract

Global climate change causes environmental temperatures to rise resulting in thermal comfort problems in humans. Thermal comfort is needed by humans in their daily lives. If thermal comfort is not met properly, it can inhibit activity, and reduce the quality of life. Humans spend 87% of their time in the building performing various activities. To improve thermal comfort in the building, air conditioning systems such as air conditioners are needed, but increased use of air conditioners will increase electricity consumption. Samudra University's multipurpose building with a glass envelope and orientation of the building in the direction of the rising sun results in direct solar radiation entering the building. The wave nature of solar radiation when it enters the glass becomes a short wave and cannot return through the glass to get out so the temperature inside increases. To minimize radiation entering the building, it is necessary to add a green facade that can absorb solar radiation heat. However, studies on the effect of green facades on buildings with glass material envelopes are still unknown. The purpose of this research is to examine how the influence of solar radiation entering the Samudra University multipurpose building on thermal comfort with experimental study methods and MATLAB simulations to obtain a thermal comfort index. The results showed that with the green façade, the indoor temperature at 12:46 pm was 38.16 ºC in the part planted with plants, while the top of the room was the hottest part because at the top there was no obstruction from the sun on the roof of the building. Based on the simulation results show that the green façade of heat entering the building undergoes absorption first so that the temperature inside the building is lower than the environment which will improve thermal comfort.

Abstract

Efforts to manage waste are being undertaken at all levels, from households to large factories that produce waste daily. The imbalance between waste production and management has made waste a significant environmental issue. One of the most challenging types of waste to decompose naturally (non-biodegradable) is plastic waste, which constitutes the largest quantity compared to other types of waste. According to statistical data, the amount of non-biodegradable waste disposed of daily at final disposal sites in several cities in Indonesia is 6,598.23 tons per day. This research has both general and specific objectives. The general objective is to utilize plastic waste as a material for making paving blocks, while the specific objective is to analyze the compressive strength properties of paving blocks made from plastic waste. By exploring the potential of plastic waste in construction materials, this study aims to provide a sustainable solution to the plastic waste problem and contribute to environmental preservation. This study used 4 types of specimens where Specimen A consisted of 80% plastic waste and 20% glass powder. Specimen B consisted of 60% plastic waste and 40% glass powder, Specimen C consisted of 40% plastic waste and 60% glass powder, Specimen D consists of 20% plastic waste and 80% glass powder. The research results showed that Specimen B achieved the highest average compressive strength value of 10.9 Mpa, indicating significant potential in supporting material strength. On the other hand, Specimen D showed the lowest average compressive strength value with only 1.2 Mpa, indicating the need for further composition adjustments to increase the material's strength. This research provides valuable insight into developing recycled materials for construction and other industrial applications.

Abstract

Fasilitas infrastruktur serta lingkungan sekitar berpotensi mengalami kerusakan lebih cepat akibat korosi. Jika korosi tidak segera ditangani, hal ini dapat menimbulkan kerugian yang cukup besar. Salah satu metode pencegahan korosi adalah proteksi katodik dengan anoda korban. Namun, karena biaya perawatan yang tinggi, teknik ini lebih sesuai digunakan dalam skala industri. Selain metode anoda korban, penggunaan inhibitor juga dapat menjadi solusi untuk mengendalikan korosi. Inhibitor adalah zat yang mampu memperlambat laju korosi meskipun diberikan hanya dalam jumlah kecil pada konsentrasi tertentu. Untuk menekan biaya perlindungan, beberapa inhibitor alami dapat dimanfaatkan dari bahan-bahan yang tersedia di sekitar, salah satunya adalah daun pepaya yang memiliki kandungan organik berpotensi menghambat proses korosi. Tujuan umum kegiatan pengabdian ini adalah memberikan edukasi kepada masyarakat mengenai pemanfaatan ekstrak daun pepaya sebagai penghambat korosi, khususnya untuk menjawab kebutuhan kelompok tani Limpah Ruah di Gampong Mekar Jaya, yang menghadapi permasalahan besi konstruksi pertanian seperti pagar yang cepat berkarat. Adapun tujuan khususnya adalah memberikan informasi mengenai cara pembuatan ekstrak daun pepaya sebagai inhibitor. Kegiatan yang dilakukan meliputi survei, pembuatan dan pengujian larutan inhibitor, serta penyuluhan kepada kelompok tani Limpah Ruah. Proyek pengabdian masyarakat ini merupakan kegiatan perdana yang dilaksanakan di wilayah Gampong Mekar Jaya.

Abstract

Global climate change, characterized by an increase in the average temperature of the Earth, is an important issue that affects human life. One of the phenomena that occurs is the Urban Heat Island (UHI) phenomenon. This phenomenon occurs due to the lack of green plants that function as absorbers of solar heat. However, the effectiveness of plants in absorbing solar heat can vary. Therefore, experimental scientific studies are needed to determine the extent to which hanging ornamental plants can absorb solar heat. This study tested five types of hanging ornamental plants to obtain heat absorption values, namely Epipremnum aureum, Chlorophytum comosum, Paperomia hopei, Discidia geri, and Tradescantia spatcheae. The results of the study found that Chlorophytum Comosum (spider plant) had the highest heat absorption value of 1 kJ. This study contributes to providing solutions for controlling environmental temperature.
