Abstract

Geostatistics is a branch of statistics that focuses on the analysis and interpretation of spatial data in earth science. Marcov chain is one of the most frequently used methods of geostatistics where this method can analyze and predict secular processes in space and time. In geology, the marcov chain method is widely used to model vertical and lateral variations in stratigraphic sequences. The research area is located in Patuk District, Gunungkidul Regency, Special Region of Yogyakarta or at coordinates S -878815 and E 110.548088. The research location is included in the Sambipitu formation, according to previous research the Sambipitu formation consists of sandstone alternating with tuffan sandstone which contains many trace fossils. The results of the marcov chain analysis showed that the highest value was found in the lithological loops of sandstones which showed that it was likely that the lithological loops would be formed in the form of sandstones and the results of the chi-squared analysis showed that the lithology in the research area was not patterned and the H1 hypothesis was rejected and H0 was accepted

Abstract

Before carrying out a reservoir simulation, porosity and permeability analysis is very important to understand the physical characteristics of the reservoir rock. Determination of these parameters helps identify the production capacity and fluid distribution in the reservoir. Correlation of core data with log data and stratigraphic simulations can provide more accurate predictions about the distribution of porosity and permeability in heterogeneous fields. Core data obtained through SCAL (Special Core Analysis) and RCAL (Routune Core Analysis) is processed into rock regions to group good and bad rock characteristics. The aim of this research is to determine rock regions based on rock permeability porosity. The method used with SCAL and RCAL analysis includes porosity, core depth permeability. After that, determine the FZI (Flow Zone Index) value obtained from the RQI (Reservoir Rock Quality Index) data divided by the NPI (Normalized Porosity Index). Then find the cumulative probability value by dividing the core sample number by the total sample number. The RQI value is obtained through permability and effective porosity data, while the NPI is obtained through porosity data. The results of research on the "ZN" formation obtained plotting between the porosity and permeability of rocks which have six rock regions based on porosity and permeability data obtained through SCAL and RCAL

Abstract

Mechanization of production equipment in UMKM an effort to increase productivity needs to get attention from higher education academics. UMKM Sari Jampi is an UMKM which operates in the field of processing herbal products. One of the products produced is the wedang uwuh This concoction requires sliced ​​ginger as one of the components in the concoction. The process of slicing ginger from the rhizome into thin flakes has been using a mechanical slicer. This slicing tool has limitations, namely inconsistent thickness, processing time, and the amount of labor. The equipment mechanization process is carried out by changing the driving force from human power to power from an electric motor. The previously reciprocal slicing mechanism has been changed to rotational. The results of this mechanization provide results in the form of thinner and more consistent slice quality, one person is required to work instead of two, and production capacity increases from 4 kg per hour to 20 kg per hour.

Abstract

This study aims to investigate the effect of varying milling durations (4 hours, 8 hours, and 12 hours) on the microstructure and hardness of Fe-C alloy powders processed using the mechanical alloying method. The mechanical alloying process involves high-energy milling to produce a homogeneous mixture with fine grain size. The variation in milling duration is expected to influence microstructural changes, such as grain size, phase distribution, and the formation of metastable phases. Microstructural analysis was conducted using electron microscopy. The results show that longer milling durations lead to finer grain sizes and an increase in martensitic phase formation. At 12 hours of milling, the grain size reached the nanometer scale, contributing to increased hardness (425 HVN) and microstructural homogeneity. Thus, the variation in milling duration significantly impacts the microstructural evolution of Fe-C alloy, with longer milling durations producing finer and more uniform microstructures. This research provides deeper insights into the relationship between milling parameters and the microstructural properties of Fe-C alloy for more optimal applications in engineering materials. .

Abstract

Hospitals are public facilities that are very much needed by the community. As technology advances, hospital facilities also develop with the presence of increasingly advanced technology. This study aims to develop and implement an Internet of Things (IoT)-based nurse calling system in hospitals using Message Queuing Telemetry Transport (MQTT) technology and the ESP8266 microcontroller. IoT is a concept that allows various devices to connect and communicate with each other via the internet, thus facilitating real-time data exchange without human interaction. This system allows patients to call nurses in real-time through devices connected to a Wi-Fi network. Messages sent from devices in each patient's room are forwarded to the MQTT server, which then sends notifications to the nurse application. Testing was carried out to measure the latency, reliability, and power consumption of the system. From the results of 100 experiments, the average latency obtained varied depending on the distance between the ESP8266 device and the Access Point, with the lowest average latency of 26.72 ms at a distance of 15 meters, and the maximum latency reaching 2897 ms at a distance of 20 meters. The system demonstrated 100% reliability, with no packet loss during testing. In terms of power efficiency, the device consumes only 0.35 watts, making it energy efficient and suitable for long-term implementation in hospital environments. With acceptable latency and high reliability, the system is expected to improve nurses’ response time to patients, as well as provide an efficient and reliable communication solution in hospitals.

Abstract

Mining of andesite at PT. Pro Intertech Indonesia is carried out through drilling and blasting activities using explosives in the form of Ammonium Nitrate and Fuel Oil (ANFO). In calculating the use of explosives based on blast geometry, several methods are used, including the theory of The Modern Technique of Rock Blasting, the ICI-Explosive theory, and linear functions based on correlation graphs. The actual blast geometry in the field has short burden, spacing, and stemming, as well as a high bench height and long charge column length, resulting in the use of 46.98 kg of explosives with fragmentation results of approximately 16 cm. Based on the designed geometry, the use of explosives would be reduced by using the ICI-Explosive theory. However, the geometry design recommended by the author is to use The Modern Technique of Rock Blasting theory, as a smaller powder factor can minimize blasting effects such as fly rock and vibration, which impact the environment. The resulting geometry design includes a burden and stemming of 2.68 m, spacing of 3.34 m, subdrilling of 0.91 m, bench height of 10.66 m, and charge column length of 9.28 m. This geometry design uses 46.19 kg of explosives per blast hole and produces a blast production volume of 243.34 tons, with fragmentation results of 20.17 cm.
