Abstract

This research aims to design an IoT-based home light monitoring system using Wemos D1 Mini. This tool is designed to control the current and voltage contained in house lights automatically. The sensor used to measure the current in the house lights is the ACS712 sensor, and the sensor used to measure the voltage in the house lights is the ZMPT101B sensor. The simulation of the house lights on this tool uses three LED lights, where each lamp is located on the terrace of the house, living room, and kitchen with different light power variations. In addition, the Blynk application on smartphones can be used to turn lights off and on and monitor currents and voltages. The test results show that this tool can control three regulated room lights and monitor the current and voltage in the three lights online using the Blynk application.

Abstract

This study details the nickel-substituted cobalt ferrite nanoparticle employing natural fine sediment (NiCFO-fs) annealing temperature dependency of crystalline and magnetic characteristics. The NiCFO-fs nanoparticles were prepared by the coprecipitation method with varying annealing temperatures (200-500°C with increment of 100°C for five hours). As a comparison, Ni-CFO was also synthesized using pure analytical chemicals (NiCFO-pa). The XRD results showed that the whole Ni-CFO nanoparticles established an inverse spinel face center cubic (fcc) order according to space group Fd-3m for both NiCFO-fs and NiCFO-pa. There was no additional peak, indicating that Ni2+ cations successfully substituted in cobalt ferrite nanoparticles. In case of NiCFO-fs nanoparticle samples, a crystallite size (D) decreased with the increasing annealing temperature (Ta), namely 45.72 nm, 37.35 nm, 25.95 nm, and 20.51 nm. In contrast to NiCFO-pa, the D increased with the increase of the Ta, i.e., 19.67 nm, 20.74 nm, 21.99 nm, and 23.33 nm. Meanwhile, FTIR results showed the presence of metal-oxygen bonds at 551-586 cm-1 and 384-391 cm-1 at tetrahedral (k1) and the octahedral (k2) sites for both NiCFO-fs and NiCFO-pa nanoparticles samples. The VSM result showed that a narrow hysteresis curve was observed for the NiCFO-fs sample compared to NiCFO-pa. The NiCFO-fs nanoparticles owing the smallest coercive field (HC) of 79.5 Oe were attained for the Ta of 300°C. In case of NiCFO-fs samples, magnetization saturation (MS) decreased with the increase of the Ta in contrast to NiCFO-pa samples. Here, the redistribution of two and three plus ions in the sub-lattice k1 and k2 locations should be encouraged by the Jahn-Teller phenomenon through strain-induced magnetism. The findings of the antibacterial test indicated that the potential of NiCFO based on natural materials (fine sediment) was higher than that of NiCFO based on pure analytical chemicals. This result was also supported by the emergence of ZOI magnitudes for all NiCFO-fs materials compared to NiCFO-pa that was only at Ta = 300°C.

Abstract

Dental health is an integral part of health in general. Maintaining dental health is important. Teeth that are not cared for or maintained in health and hygiene can damage teeth such as caries, periodontal disease, and fractures when traumatized. Therefore, if the tooth is left in such a state, it can potentially lose the tooth. Dentures are prostheses that replace some or all of the missing natural teeth and surrounding tissues. The use of dentures can be influenced by several factors such as the high cost of making dentures, the length of time it takes to make dentures and the lack of public knowledge about the benefits of using dentures. The purpose of the study was to determine the level of knowledge of patients about the use of dentures after permanent tooth extraction at the Molawe Health Center based on gender, age, education, occupation and income. This study is a descriptive research with a cross sectional approach using the total sampling technique and the number of samples as many as 37 respondents. The results showed that the relationship between knowledge level and gender was obtained with a p-value of 0.473, the relationship between knowledge level and age was obtained with a p-value of 0.023, the relationship between knowledge level and education was obtained with a p-value of 0.000, the relationship between knowledge level and employment was obtained with a p-value of 0.004, and the relationship between knowledge level and income was obtained with a p-value of 0.005. This study shows that there is no relationship between the level of knowledge and gender on the use of dentures after tooth extraction. Furthermore, there is a relationship between the level of knowledge and age, education, occupation, and income on the use of dentures after tooth extraction.

Abstract

Chewing food with one side of the mouth will cause thick and strong muscles only on that side. The facial muscles on the right and left sides will become asymmetrical. Chewing one side is one of the bad habits that can affect the hygiene status of teeth and mouth. Dental and oral hygiene can be measured by an index with good, medium, bad criteria. The measurement used is with OHI-S (oral hygiene index simplified).. This study aims to determine whether there is a one-sided chewing relationship with dental and oral hygiene status in people aged 30-40 years, Simae Environment, Baranti District, Sidrap Regency. This type of research is descriptive correlative with a cross sectional approach. Sampling was carried out using purposive sampling techniques and obtained 44 respondents. The results of the correlative descriptive test showed that there was a relationship between one-sided chewing and OHI-S status in people aged 30-40 years, Simae Environment, Baranti District, Sidrap Regency, namely chewing using one side by 72.7% of medium criteria.

Abstract

When the COVID-19 pandemic hit almost all countries, all activities were limited and it was recommended to stay indoors, including the online learning process. This research is based on problems that occur in the learning process during the Covid-19 pandemic. Overcome this problem, it can be done using interactive media. This study aims to determine the development of technology in the world of education. One of them is interactive media-based learning media. In learning media, interactive media can be further developed to be varied so that the function of the media becomes wider. The development of media is not easy, but the need for an effort to maximize it. Therefore, the use of media is very important to improve and support the delivery of material. Interactive media usually refers to a computer system service that responds to actions between users in presenting material, such as text, images, animation, video, and audio.

Abstract

This study aims to analyze inpatient data using the K-Means Clustering method on a simulated dataset. The dataset includes various patient-related attributes such as age, billing amount, length of stay, medical condition, and type of admission. Several preprocessing steps were applied, including date conversion, duration calculation, numerical normalization, and one-hot encoding for categorical attributes. The Elbow Method was used to determine the optimal number of clusters, and clustering quality was evaluated using both the Silhouette Score and Davies-Bouldin Index. The analysis results show that the patients can be segmented into three major clusters, each exhibiting distinct characteristics—for example, younger patients with short and low-cost stays, and elderly patients with prolonged and more expensive hospitalizations. The resulting Silhouette Score of 0.14 and Davies-Bouldin Index of 1.74 reflect a moderate clustering performance, yet the model remains informative and meaningful. These clusters provide actionable insights that hospitals can use to optimize their service strategies, improve resource allocation, and enhance operational efficiency. Moreover, the study illustrates the practical application of unsupervised learning techniques in healthcare settings, contributing to data-driven decision-making practices and offering a foundation for further research into patient segmentation.

Abstract

This study aimed to evaluate the effect of temulawak extract nanoemulsion (Curcuma xanthorrhiza Roxb.) supplementation in drinking water on the production performance and Income Over Feed Cost (IOFC) of broiler chickens. The study utilized 100 broiler chickens of the Loghman MB 202 Platinum strain, which were randomly assigned into four treatments: P0 (control), P1 (4 mg/kg body weight), P2 (6 mg/kg body weight), and P3 (8 mg/kg body weight), with five replications per treatment. Data were analyzed using one-way ANOVA followed by Duncan’s multiple range test. The results showed that the P2 treatment (6 mg/kg) produced the best performance, with a final body weight of 1,677 g/bird, feed intake of 202.83 g/bird, and the lowest feed conversion ratio of 1.34. The highest IOFC was also observed in P2, amounting to Rp11,367/bird. In conclusion, supplementation of temulawak extract nanoemulsion at a dose of 6 mg/kg body weight effectively improved production performance and IOFC in broiler chickens and is recommended for implementation.
