The Covid-19 virus can be transmitted in various ways, including direct contact with sufferers, so that there are many cases of Covid-19 patients who die during self-isolation. The cause is lessened oxygen levels in the blood or a medical term called Happy Hypoxia. Under normal conditions, the value of oxygen levels in the blood ranges from 95-100% and abnormal conditions <95%, while the standard heart rate ranges from 60–100 beats per minute (BPM). In general, a person feels normal and healthy without realizing his blood when experiencing a lack of oxygen. Therefore, it is necessary to measure oxygen levels in the blood periodically. Pulse oximeters are already on the market. Not many people have it. The pulse oximeter does not have a remote check feature. In addition, the use of a pulse oximeter at home is still controlled directly by the officer manually so that it is possible to interact directly. This tool can display data such as room temperature, body temperature, oxygen level data (SP02), and heart rate (BPM) of the patient. The device can work properly by sending patient health data remotely in real-time. So this research can help medics analyze and take action quickly. From the results of testing oxygen levels, the average error value is 0.01 or 1%. This value is still within the tolerance limit. So can use this tool to assist media workers in analyzing patient conditions remotely and making decisions about giving treatment to patients.

Diabetes is one of the diseases with the highest number of sufferers worldwide. In addition, diabetes is in the top 10 leading causes of death and has been significantly increasing since 2000. If not treated quickly, diabetes will be very dangerous for the human organs, especially the parts of the body traversed by blood vessels. Therefore, this study aims to detect early stage diabetes. So that the treatment of diabetes is faster before it develops into a more serious direction. The begging technique on the PSO-based C4.5 algorithm is applied to determine the accuracy of this algorithm model in classifying people with diabetes. The bagging method and Particle Swarm Optimization (PSO) aim to address the weaknesses of the C4.5 algorithm in overlapping data, a large number of attributes, and classes. According to the experiments, the bagging technique on the PSO-based C4.5 algorithm produces a better accuracy value by approximately 95.58%, while the C4.5 algorithm ware 90.38%.

Abstract Background: Several studies have been published on the characterization of Trimeresurus venoms. However, there is still limited information concerning the venom composition of Trimeresurus species distributed throughout Indonesia, which contributes to significant snakebite envenomation cases. The present study describes a comparative on the composition of T. albolabris, T. insularis, T. puniceus, and T. purpureomaculatus venoms originated from Indonesia. Methods: Protein content in the venom of four Trimeresurus species was determined using Bradford assay, and the venom proteome was elucidated using one-dimension SDS PAGE nano-ESI- LCMS/MS shotgun proteomics. Results: The venom of T. albolabris contained the highest protein content of 11.1 mg/mL, followed by T. puniceus, T. insularis and T. purpureomaculatus venom with 10.7 mg/mL, 8.9 mg/mL and 5.54 mg/mL protein, respectively. In total, our venomic analysis identified 65 proteins belonging to 16 protein families in T. purpureomaculatus; 64 proteins belonging to 18 protein families in T. albolabris; 58 different proteins belonging to 14 protein families in T. puniceus; and 48 different proteins belonging to 14 protein familiesin T. insularis. Four major proteins identified in all venoms belonged to snake venom metalloproteinase, C-type lectin, snake venom serine protease, and phospholipase A2. There were 11 common proteins in all venoms, and T. puniceus venom has the highest number of unique proteins compared to the other three venoms. Cluster analysis of the proteins and venoms showed that T. puniceus venom has the most distinct venom composition. Conclusions: Overall, the results highlighted venom compositional variation of four Trimeresurus spp. from Indonesia. The venoms appear to be highly similar, comprising at least four protein families that correlate with venom’s toxin properties and function. This study adds more information on venom variability among Trimeresurus species within the close geographic origin and may contribute to the development of optimum heterologous antivenom.

Geographic Information System Technology makes it easier for us to manage geo-referenced information data or mapping the location of an area that is connected to the database. Nahdlatul Wathan is one of the largest organizations in West Nusa Tenggara, where there has been rapid development from year to year, especially in the field of education. The number of Islamic schools (madrasas) under the Nahdlatul Wathan organization is increasing every year. But until now, the location (geographical location) of each school is still not well recorded and mapped. Therefore, we need a geographic information system that can be used for the process of mapping and data collection of schools under the Nahdlatul Wathan organization that can help the management of Nahdlatul Wathan and each Islamic school and community to find out the location. from each school, which can be accessed quickly and precisely.

the development of information technology is currently progressing, multimedia is one of the right way to facilitate the delivery of information in the form of audiovisual form of 3D animation. Utilizing multimedia to convey information is as one way in an effort to publish the traditional architecture of the Lombok area, especially the traditional house of Belek Sembalun Lawang Village in the form of 3D animation using blender software that can be used as a medium of learning. Belek Village is a large village/village parent which was first created consisting of seven houses that are the forerunner of Sembalun Village. By using 3D animation is expected to provide solutions and alternatives in the process of introduction and learning about the traditional architecture of Lombok traditional house especially the traditional house of Belek Village, so that in the process of learning and recognition becomes more unique and interesting, as well as learning media and introduction of traditional house of Belek Village, 3D animation can also provide an advantage in publication efforts and documentation of history and culture of Sembalun Lawang Villag.
