This study investigates the grain size characteristics and sediment types of the Aceh's coastal deposits that are primarily based on the sieve analysis. This study is mainly driven by two reasons. Firstly, this study is a preliminary effort to identify coastal sediment in the Aceh coastal areas. Secondly, this information is important to interpret the support mechanism of sediment during transportation and depositional processes. In this study, many sediment deposits from both the east and west coasts of Aceh were collected. Laboratory sieve analysis was carried out to these samples. Then, further analysis of this sieve analysis results is carried out. The analysis reveals the past transport mechanism of this study sand deposits which is river's channel. However, such finding should be investigated further as all the tested sand were taken at the top surface and big main rivers are not indicated at both sand locations.

Diabetes mellitus (DM) is metabolic disease causing hyperglicemia due to insulin action anomali. DM can cause cellular changes, including buccal cell. Blood tests are used to diagnosis diabetes, so non-invasive test is required for diagnosis of diabetes. Accordingly, this research aims to design non-invasive system based on artificial neural network for type 2 DM detection using buccal cell images. Buccal cells smears were obtained from 30 subjects suffering from type 2 DM and 30 normal subjects. The smears were stained by using Papanicolaou method. Each slide were observed under digital microscope and were evaluated. The system was designed by using MATLAB with image processing and Probabilistic Neural Network (PNN) algorithm to classify features. Buccal cell images were segmented to get features. The features used in this study were nucleus area, nucleus perimeter and nucleus circularity. Nucleus areas and perimeters in type 2 DM group were higher than those in control group with similar nucleus roundness in both groups. Forty nucleus feature datasets were used for training process, while 20 nucleus feature datasets were used for testing process. The optimal PNN value was 0.4 g constant. The optimal accuracy of training was 92.5%, while the optimal accuracy of testing was 90%.

Identifying cues to contagious disease is critical for effectively tracking and defending against interpersonal infection threats. People hold lay beliefs about the types of sensory information most relevant for identifying whether others are sick with transmissible illnesses. Are these beliefs universal, or do they vary along cultural and ecological dimensions? Participants in 58 countries (N = 19,217) judged how effective, and how likely they were to use, cues involving each of the five major sensory modalities in an imagined social interaction during a flu outbreak. Belief patterns were strongly consistent across countries (sight > audition > touch > smell > taste), suggesting a largely universal conceptualization of the role of sensory information for interpersonal respiratory disease detection. Results also support a safe senses hypothesis, with perceivers reporting that they would use senses that function at a distance—and thus reduce pathogen transmission risk—more than would be expected given participants’ beliefs as to the efficacy of these senses for disease detection. Where societal variation did emerge, it was captured by a cohesive set of socio-ecological factors, including human development, latitude, pathogen prevalence, and population density. Together, these findings reveal a shared lens through which contagious respiratory disease is assessed, one that prioritizes minimizing risk to perceivers, and may offer leverage for designing interventions to improve public health. © 2025 Elsevier Inc.

Bisindo or Bahasa Isyarat Indonesia is one of sign language methods in Indonesia, besides SIBI or Sistem Isyarat Bahasa Indonesia. Generally, Bisindo is used by deaf people in their daily communication. Deaf people tend to have barriers to communicate with others. Yet, in the educational realm, some of them still have high spirit to continue their education until university. So, they must improve their abilities or competences in communicating with others and try to get information from around the world, for example using sophisticated technology with sign language. Information system of sign language learning is important to help deaf and heard people who want to understand the deaf conversation meaning. Bisindo information system is in website form that is built by PHP, MySQL, and sublime text 3. Based on the black box method, the Bisindo information system can run well. The results of the trial to the user describe that the maximum percentage for each level of testing is above 50% except for testing of conformity with the needs of deaf only at maximum of 42%. The Bisindo information system still has weakness, but it already gives benefits especially for deaf people in Indonesia.

Fuel motor is a machine that converts chemical energy into mechanical energy. In the design of this approach, we look for a gas converter model in accordance with its capacity according to the volume of the cylinder used, where the thing that needs to be considered is the performance of the gas converter itself, namely from the art form/model, fuel efficiency and large pressure settings. gas supply that enters the combustion chamber. The GX270 general motor is a fuel motor engine used as a test tool. The design was carried out at the STT Muhamadyah Cielungsi mechanical engineering energy conversion laboratory. To understand the variables that affect performance, in making this converter, things that need to be considered are variations in rotation and variations in load. From the design of the gas converter, the results of the design calculation are as follows: T torque = 19.12 (Nm), effective power Ne = 5.003066667 (kW), average effective pressure Pe = 889.4340741 (kPa), total usage hourly fuel mf = 0.0675 (kG / hour), specific fuel consumption Be = 0.013491725 (kg / kN.m), fuel ratio with air F / A = 0.13781, ideal air mass flow rate mv = 0,0,001138242 (m3 / s), volumetric efficiency 843,30666 (%) and thermal efficiency 15,78 (%), the greater the engine rotation used, the more fuel level will be consumed, as well with effective engine power.

Preliminary Gravity study of Pre-Tertiary and Tertiary Rock in Northern Kebumen, Central Java, Indonesia

引用

IOP Conference Series: Earth and Environmental Science 2019年第1期318卷

作者： Faridz Nizar Ahmady Djoko Santoso Geophysical Engineering Study Program Faculty of Mining and Petroleum Engineering Institut Teknologi Bandung Bandung 40132 Indonesia Applied Geophysics Research Group Faculty of Mining and Petroleum Engineering Institut Teknologi Bandung Bandung 40132 Indonesia

Luk Ulo Melange Complex is a Pre-Tertiary rock formation consisting of various lithological background and complicated geological structure. Located in Northern Kebumen Regency, this rock is originally interpreted as products of tectonic process caused by paleo-subduction between Indian Oceanic Plate beneath Eurasian Plate in Cretaceous age. According to previous study on geological surface investigation shows that the melange complex is tectonically overlain by Tertiary sedimentary formation. On the contrary, geophysical study of the subsurface condition of the area is still under discussion due to limited of measured data. In order to obtain detailed subsurface image, gravity profiling was measured and interpreted across both Tertiary and pre-Tertiary rock. Frequency domain filter and designed moving average filter were used to separate residual and regional anomaly. The results denote gravity value of residual anomaly varying from -5 to +5 mGal, while regional anomaly is ranging from 150-180 mGal respectively. The preliminary interpretation was developed by taking into account the geological information and also the data that was collected during field campaign. Overall, high gravity anomaly is interpreted as diabase intrusion in the middle of research area. Meanwhile, low gravity anomaly indicated clay rich rock material related to matrix content of Luk-Ulo Melange Complex in the northern area.

作者： Ismaiba Riries Rulaningtyas Katherine Ernawati 1Biomedical Engineering Program Study Faculty of Science and Technology Universitas Airlangga Campus C Zip Code: 60115 Surabaya East Java Indonesia 2Fetomaternal Division of Obstetrics and Gynecology Department Faculty of Medicine Universitas Airlangga Campus A Zip Code: 60131 Surabaya East Java Indonesia

The maternal mortality rate in Indonesia is related to the lack of knowledge of mothers regarding high-risk pregnancies, especially with cesarean delivery. In this case, the prediction system designed is done as an effort to increase the awareness of mothers or women who were preparing for high-risk pregnancies. In this article, an Android-based prediction application will be presented using an expert system with the Dempster Shafer method. This method is based on a mathematical theory which consists of a combination of belief function and plausible reasoning from the risk parameters of each labor class by representing the knowledge obtained from experts. This study uses 16 risk parameters as input based on Poejo Rochati's high-risk pregnancy card with 2 outputs, with risk or no risk of having cesarean delivery. The result obtained from this system is 85%, concludes that the prediction system is able to predict the risk of cesarean delivery.
