Zeebaree, Renas Rajab Asaad, Dilovan Asaad Majeed, Amira Bibo Sallow, Hawar Bahzad Ahmad First page: 1 Abstract: Safety and privacy are seriously threatened by IoT devices enabling smart homes that have security flaws. It is not feasible to use a single network management strategy for all of these devices due to their differing Value of Service (QoS) needs. By detecting rogue or susceptible devices and automate network operations depending on device type or function, device categorization may be used to improve IoT security and management in order to solve these issues. Due to this, there is already a growing body of research on the use of machine learning for traffic analysis with the purpose of automatically classifying devices and identifying hidden patterns in Internet of Things data. In order to comprehend these techniques' potential and limitations, this study explores them in depth. It begins with describing a broad process for categorising IoT devices and then delves further into methods and fixes for every stage of the workflow. Among the important elements discussed are: categorization of public datasets in addition to analysis of IoT traffic data collecting situations and techniques. The literature on IoT traffic extraction of features is evaluated; common features are classified and compared, free feature extracting tools are described, and machine learning techniques for IoT device classification are summarised and evaluated. The results of this investigation are shown in taxonomies along with information that shows trends found in the literature. In addition, the study looks at and recommends uncharted or understudied research directions in this developing sector.

Zeebaree First page: 11 Abstract: A worldwide emphasis on lowering energy use has been prompted by a noticeable rise in energy consumption in recent years, especially in the housing sector. The idea of "smart houses" emerged as a result of advancements in energy conversion techniques, communication networks, and information technology. The confluence of varied technologies across application industries has given rise to the Internet of Things (IoT), which allows things to be connected via the World Wide Web for remote device management, monitoring, and detection. Enhancing energy efficiency through the integration of IoT, big data, and machine learning technologies with automation systems for homes is a promising approach. This paper presents HEMS-IoT, a big data and machine learning powered holistic energy control system for intelligent houses that puts security, convenience, and energy efficiency first. In order to identify user behaviours and patterns of energy use, the J48 neural network technology and the Weka API were utilised in the study. This method made it possible to classify households according to how much energy they used. Furthermore, to guarantee user comfort and safety inside smart homes, RuleML and Apache Mahout, also known were implemented. These technologies exploit the user's preferences to deliver tailored recommendations for energy-saving actions. The paper provides a workable example of how a smart home might be monitored to guarantee security and comfort while cutting down on energy consumption. This demonstration confirms the efficacy of the technique suggested in the research. PubDate: 2024-05-02 DOI: 10.22437/jiituj.v8i1.32598 Issue No:Vol. 8, No. 1 (2024)

Authors:Jade O Hizon, Nikki Y Cruz, Leila M. Collantes, Joel M. Torres, Amirul Mukminin First page: 170 Abstract: Using a pretest-posttest quasi-experimental design, the study investigated the effect of Concept Cartoons in teaching Evolution on the academic achievement of 40 Grade 11 STEM students taking General Biology 2 in a synchronous teaching mode. Moreover, the researchers determined the students’ misconceptions on basic concepts in Evolution using Concept Cartoons as a formative tool implemented in an online platform. Students were divided into control (n = 21) and experimental (n = 19) groups, where the control group was taught using the traditional lecture method while the experimental method was taught using Concept Cartoons administered online. Findings revealed that students hold a series of misconceptions on the topics under Evolution. Paired sample t-test showed a statistically significant difference between pre-test and post-test scores for both experimental and control groups. However, when post-test scores of experimental and control groups were compared, independent t-test results revealed that there was no significant difference between experimental and control groups to their achievement. Thus, this study discussed the two possible factors for this incongruence that may act separately or in combination: (1) administration of Concept Cartoons in digital media and (2) uncontrolled technical problems during synchronous classes. The present study provided initial information that Concept Cartoons may not be as effective as it is in synchronous learning modality, which is important to note especially for science teachers who are transitioning their materials used in face-to-face classes to online modality amidst pandemic.

Authors:Febriansyah Febriansyah, Albadi Lijaya, Rukmini Rukmini, Ra. Hoetary Tirta Amallia, Novin Teristiandi, Andi Saputra, Siti Soleha Pages: 203 - 211 Abstract: Small-scale gold ore processing areas have become a global concern due to their significant contribution to heavy metal pollution. The residual amalgamation process in these areas leads to the accumulation of heavy metals in the environment, which can bioaccumulate in living organisms. This study focuses on the lime plant (Citrus aurantifolia), commonly found in small-scale gold ore processing areas, particularly in Sukamenang village. The research aims to assess the Bioconcentration Factor (BCF) and Estimated Daily Intake (EDI) of heavy metals in lime plants to evaluate the risk to residents who consume them. Samples were collected using random sampling and analyzed with an Atomic Absorption Spectrophotometer (AAS) and a mercury analyzer. The results indicate that Citrus aurantifolia has a BCF value of less than 1 (<1), classifying it as an excluder plant, effectively preventing heavy metals from entering its upper parts and allowing it to thrive in polluted environments. However, the consumption of these plants poses health risks. The study highlights the Reference Dose (RfD) values for heavy metals: Cu at 4.0 x 10^-2 (0.008), Fe at 0.7, and Hg at 0.0001, as recommended by the United States Environmental Protection Agency (USEPA) in 2011. Heavy metals such as Fe, Cu, and Hg in the lime plants indicate potential adverse health effects due to their toxicity. This research underscores the necessity for monitoring and mitigating heavy metal pollution in small-scale gold ore processing areas to protect public health and the environment.

Authors:Agus Sutanto, Kartika Sari, Handoko Santoso, Hening Widowati, Hasminar Rachman Fidiastuti, Yaya Rukayadi Pages: 212 - 230 Abstract: One way to decompose the pond waste sediment is to use the liquid nutrient culture media (NB) called Pumakkal as a starter formula. However, bioremediation in shrimp ponds paid less attention despite being massively promoted by the official government. East Lampung produced 11.6 million m3 of liquid waste and 4.077 m3 of sediment waste in shrimp ponds rich in organic matter. However, they will poison the pond if they are unchecked. This study investigated how Pumakkal decomposed shrimp pond waste with three parameters: macronutrients, micronutrients, and pH. The study employed laboratory experiments, and the research was a completely randomised design (CRD) with 15 factorial arrangements. The sample was 65 kg of shrimp pond waste and 65 litres of liquid waste. They were analysed with five treatment experiments: three treatments of liquid waste media (LW), sediment waste (SW), and mixed liquid and sediment waste (MLS). The results showed that the treatment of the CE 15 isolate (with MLS significantly improved (p<0.05) fertiliser quality. Bioremediation using Pumakkal CE is the best treatment with MLS, obtaining the fertiliser with the best macronutrient: Nitrogen (N) 1,3%, Phosphorus (P)2,3%, and Potassium (K) 2,3%; C-organic 23%, C/N ratio 29; micronutrient: Fe:155 ppm, Cu: 51 ppm, Zn: 72 ppm, Mn; 51 ppm, B; 25 ppm, and Mo: 8 ppm, and pH 5-6. The mixture of liquid and pond sediment waste produces the best fertiliser suitable for plant fertiliser users. The study implies that Pumakkal applies to decomposing harmful waste sediment to support the bioremediation program. PubDate: 2024-05-14 DOI: 10.22437/jiituj.v8i1.32094 Issue No:Vol. 8, No. 1 (2024)

Authors:Tran Van Hai First page: 284 Abstract: In the context of human resources in the securities industry being depleted after the Covid-19 pandemic, with strong fluctuations and many risks, maintaining and improving the quality of human resources to meet the an urgent new development stage for the sustainable development of securities companies. Recent studies around the world to meet the needs of workers mostly focus on fields such as banking, manufacturing, etc. The results show that leadership style or salary has a direct impact on meeting the needs of workers. However, the securities industry with young human resources in developing countries like Vietnam has its own differences. The goal of the study is to clarify the relationship between satisfaction, engagement and financial performance in securities companies in Vietnam after the Covid-19 pandemic. Sample data was collected online by the authors from 225 employees working at securities companies in Vietnam, in the period from September 2023 to December 2023. Using quantitative research on the PLS-SEM linear structural model on SPSS 20 and AMOS 20 software, the results show that securities employees are not really satisfied with their current job, identifying 2 factors. Factors that have a strong influence on the financial performance of securities companies include: (1) Training and advancement and (2) Working environment. This is consistent with the characteristics of securities human resources in Vietnam. The study adds to the understanding of meeting employee needs through training and improving the work environment, which in turn will improve a company's financial performance.

Authors:Heriberta Heriberta, Zulfanetti Zulfanetti, Rike Setiawati First page: 310 Abstract: This groundbreaking research explores the intricate interplay between age factors, motivation to work, and the self-determination of mothers engaged in the informal employment sector, a demographic often overlooked in scholarly investigations. Employing a mixed-method approach characterized by a sequential exploratory design, this study pioneers a comprehensive examination of the multifaceted dynamics shaping maternal self-determination. Leveraging purposive sampling, data collection unfolds through a meticulously orchestrated blend of orally administered questionnaires and in-depth interviews, ensuring a holistic understanding of the subject matter. Analytically, the research employs a dual-pronged strategy encompassing descriptive and inferential statistical analyses, complemented by Miles & Huberman's framework for interview analysis. The study unveils a significant nexus between age, motivation, and maternal self-determination through rigorous statistical scrutiny, filling a conspicuous void in extant literature. This research's novelty lies in its explicit focus on delineating the intricate correlations and synergies between age and motivation factors vis-a-vis self-determination, particularly within the context of working mothers operating within informal economies, an underexplored realm in academic discourse. The implications of this study reverberate far beyond academia, offering tangible insights that can inform the development of targeted support programs tailored to empower and uplift mothers navigating the informal employment sector. Ultimately, this research represents a pioneering stride towards fostering a more inclusive and equitable ecosystem for working mothers, underpinned by a nuanced understanding of their unique challenges and aspirations.

Authors:Syamsurizal Syamsurizal, Elisma Elisma, Puspa Dwi Pratiwi Pages: 325 - 333 Abstract: The sun's ultraviolet radiation causes erythema, premature aging, sunburn, hyperpigmentation, inflammation, and dry skin. For this purpose, sunscreen with an SPF value of over 15 is needed to protect the skin against UV rays. Breadfruit peel containing flavonoids may protect against free radicals and UV radiation. This study aims to increase SPF value from breadfruit fractionate by combining niacinamide and alpha-tocopherol. The ABTS and BSLT methods were used to screen potent free radical scavengers in n-hexane, dichloromethane, ethyl acetate, and methanol extracts. The dichloromethane extract had the highest potential as a free radical scavenger, with IC50 20,90 more or less 0,54, and the lowest toxicity, with LC50 234,42 more or less 1,06. Then, the scavenging activities and selective index of fractionates of dichloromethane were evaluated to show that the DM2 fraction had the strongest free radical scavenging activity and the lowest toxicity, with the highest selective index value of 46.08. The main active ingredient was DM2, combined with niacinamide and alpha-tocopherol into five compositions. The results of the lotion dosage forms revealed that the fifth formula, F5, met the requirement SNI standards and was stable during storage, with an SPF value of 20.61 more or less than 0.75, which was three times higher than the positive control with an SPF value of 6.67 more or less 1.28.

Authors:Desi Novita, Tavi Supriana, Sirozujilam Sirozujilam, Satia Negara Lubis Pages: 334 - 349 Abstract: Sustainable agriculture is an important factor in preserving sustainable development in an area. Red chili is a commodity that has a strategic role in the agricultural sector. This research aims to measure the endemic index in the red chili agribusiness system in North Sumatera Province. Data collection was carried out through in-depth interviews involving farmers, marketers, extension workers, and local governments using five dimensions of climbing. The data analysis method used was Multi-Dimensional Scaling (MDS), called RAP-Chili (Rapid Appraisal for Chili). The results show that the combined index for the red chili agribusiness system in this province is quite sustainable, with an index value of 58.94. Only one dimension is included in the high desire index level (78.35), namely the environmental dimension. Meanwhile, the other four dimensions are at the level of the quite desirable category, namely the economic dimension (52.82), the socio-cultural dimension (57.30), the partnership dimension (54.24), and the institutional dimension (51.98). Overall performance can be improved by making improvements in each dimension. Therefore, policy planning for developing the red chili agribusiness system must improve weak indicators and impact existing dimensions. Environmental aspects regarding land suitability, climate, and fertility must continue to be improved, considering that agriculture in Indonesia is still very dependent on natural resource factors.
