Intrusion Detection System provides services related to surveillance of computer security, as one of the minimum components that must exist in a computer network architecture. Regarding the adoption of cloud technology, many users have switched to using cloud computers to operate servers, applications, or the web in cloud computing. To meet the security needs of users, various open source and commercial tools are being developed. Although many developments have taken place in the IDS area, in cloud-based IDS many challenges such as security, interoperability, resource scheduling, virtualization still need to be improved. This paper reviews the paradigms and surveys about the Intrusion Detection System that runs on cloud computing in terms of concepts, technology, tools, and various challenges. A systematic literature review of selected papers, published from 2016 to 2020, was carried out to properly understand the Intrusion detection System paradigm in cloud computing and the security challenges faced in cloud computing. This review paper helps researchers who want to start their research careers in the cloud computing-based Intrusion Detection System

Thalassemia is known as one of the blood disorder diseases that is inherited by parents. There are several types of Thalassemia, namely as Thalassemia major, minor, and intermedia. Among them, Thalassemia major is the most dangerous and needs more attention. Generally, it can be detected since the child is one year old. Late detection of this disease can have adverse consequences and various complications. This study aims to develop a new model for the prediction of thalassemia for children. The model adopts a fuzzy-based rule. The novelty in this article is that our model has 4 outputs, namely thalassemia major, intermedia, minor and not thalassemia. In the previous article it only had 3 outputs. In this study, we intend to implement a model that we developed using a fuzzy-based approach to classify thalassemia diseases based on CBC data. This article describes how to build a model and implement it in software. We compare the test results with the opinion of pediatricians regarding thalassemia. The final results of testing 4 CBC data show that our proposed model has successfully identified the type of thalassemia. © Published under licence by IOP Publishing Ltd.

Students' conceptual and procedural knowledge on integration: Reflections on calculus learning

引用

AIP Conference Proceedings 2023年第1期2698卷

作者： Aniswita Ahmad Fauzan Armiati 1Doctoral Program of Educational Science Universitas Negeri Padang Padang Indonesia 2Department of Mathematics Universitas Negeri Padang Padang Indonesia

This study aims to describe conceptual and procedural knowledge on integral topics. Data were collected from 30 students who were randomly selected from 120 students of the mathematics education study program at IAIN Bukittinggi who took an integral calculus course. Data were analyzed by categories from student's work. The results showed that students' conceptual knowledge is still very low. Students do not understand the meaning of the definite integral as the limit of the Riemann sum and build a definition of the integral. Most of the students had a fairly good knowledge of procedural aspects. Students can determine the integral of a function using the basic theorems of calculus and can use the right integration technique for some given functions. On the other hand. Integral calculus learning is expected to increase students' conceptual knowledge in addition to their procedural knowledge.

High-quality fluorescence imaging of biological systems is limited by processes like photobleaching and phototoxicity, and also in many cases, by limited access to the latest generations of microscopes. Moreover, low temporal resolution can lead to a motion blur effect in living systems. Our work presents a deep learning (DL) generative-adversarial approach to the problem of obtaining high-quality (HQ) images based on their low-quality (LQ) equivalents. We propose a generative-adversarial network (GAN) for contrast transfer between two different separate microscopy systems: a confocal microscope (producing HQ images) and a wide-field fluorescence microscope (producing LQ images). Our model proves that such transfer is possible, allowing us to receive HQ-generated images characterized by low mean squared error (MSE) values, high structural similarity index (SSIM), and high peak signal-to-noise ratio (PSNR) values. For our best model in the case of comparing HQ-generated images and HQ-ground truth images, the median values of the metrics are 6·10-4, 0.9413, and 31.87, for MSE, SSIM, and PSNR, respectively. In contrast, in the case of comparison between LQ and HQ ground truth median values of the metrics are equal to 0.0071, 0.8304, and 21.48 for MSE, SSIM, and PSNR respectively. Therefore, we observe a significant increase ranging from 14% to 49% for SSIM and PSNR respectively. These results, together with other single-system cross-modality studies, provide proof of concept for further implementation of a cross-system biological image quality enhancement. © 2024, CC BY-SA.

Analysis of chili demand in Indonesia

引用

AIP Conference Proceedings 2023年第1期2583卷

作者： Mei Tri Sundari Darsono Joko Sutrisno Ernoiz Antriyandarti 1Doctoral Program of Agriculture Science Graduate School of Universitas Sebelas Maret Surakarta Central Java - Indonesia 2Agribusiness Study Program Faculty of Agriculture Universitas Sebelas Maret Surakarta Central Java - Indonesia

The increase in population that continues to increase every year and the national economic growth impacts the increase in chili demand, both from households, processing and food industries, and export needs. The price also influences the demand for chili products in the market. When chili production is abundant, the price of chili will be very low and demand will increase, but on the contrary, when chili production decreases, the price of chili will be high and demand will decrease. Therefore, this study aims to analyze the factors that influence Indonesian chili demand and determine the elasticity of chili demand in Indonesia. The data used in this study is data from 2005 to 2019. The analytical method used is multiple linear regression analysis. The results showed that the independent variables that significantly affected the Indonesian chili demand are income per capita, garlic price, and chili export price. The price elasticity of 0.134 indicates that the demand for red chili is inelastic. Shallots and garlic are complementary goods with elasticities of -0.285 and -0.060. The income per capita elasticity is 3.115, indicating that the percentage of red chili demand will increase if income increases.

AIP Conference Proceedings 2023年第1期2568卷

作者： I. Made Astika I. Nyoman Suprapta Winaya I. Ketut Gede Wirawan Akhmad Herman Yuwono I. Dewa Gede Ary Subagia 1Doctoral Study Program of Engineering Science Faculty of Engineering Udayana University Kampus Sudirman Denpasar Bali 80234 Indonesia. 2Study Program of Mechanical Engineering Faculty of Engineering Udayana University Kampus Bukit Jimbaran Badung Bali 80361 Indonesia 3Department of Metallurgy and Materials Engineering Faculty of Engineering Universitas Indonesia Kampus Baru UI Depok Depok 16424 Indonesia

Composite materials are a combination of several materials to form a new material with specific properties. Chemical compatibility of the constituent materials is a factor that affects the characteristics of composite materials. Currently, composite phase change materials (PCM) are commonly applied as thermal energy storage systems. This study investigated the characteristics of beef tallow/rice husk charcoal/plaster PCM composite. The weight fraction of rice husk charcoal used was 10%. To prevent leakage of beef tallow from the composite structure, the researcher used polyvinyl acetate (PVAc) to cover the tallow/RHC composite before mixing it with plaster material. As much as 30% of the tallow/RHC/PVAc composite weight fraction is integrated into the plaster. PCM composite was made by using a direct incorporation method. The FTIR test results on the PCM composites produced showed good chemical compatibility among different components. The scanning electron microscope results showed the formation of microcapsules where the rice husk charcoal and polyvinyl acetate functions as a wrapper/capsule for beef tallow. This composite is suitable for application in building walls as thermal energy storage.

Characterization and performances of hydrophobic polymer membrane modified with dragon’s blood resin

引用

AIP Conference Proceedings 2023年第1期2613卷

作者： Aulia Chintia Ambarita Sri Mulyati Nasrul Arahman Muhammad Roil Bilad 1Doctoral School of Engineering Science School of Engineering Post Graduate Program Universitas Syiah Kuala Banda Aceh 23111 Indonesia 2Department of Chemical Engineering Faculty of Engineering Universitas Syiah Kuala Banda Aceh 23111 Indonesia 3Department of Chemical and Process Engineering Faculty of Integrated Technologies Universiti Brunei Darussalam Jalan Tungku Link-Gadong BE1401 Brunei

Hydrophobic membranes have limitations, which are the low permeation rate and susceptible to fouling, therefore membrane modifications are generally required. In this paper, hydrophobic polymer membrane modification has been studied by mixing dragon's blood resin (DBR) as bio additive. Two types of polymers were used, they were polyethersulfon (M-3 PES) and polyvinylidene Two types of polymers were used, they were polyethersulfon (M-3 PES) and polyvinylidene fluoride (M-3 PVDF) with a concentration of 14.5% polymer and 3% DBR. The results showed that M-3 PES had greater porosity, water uptake, pore size, and clean water flux than M3-PVDF. However, the antifouling performance of M-3 PVDF membrane tends to be better than M-3 PES, as well as its rejection. Both membranes tend to be stable even after repeated use.
