Abstract

          Energy resources are resources that can be processed by humans so that they can be used to meet energy needs. Water resources are a renewable natural resource that has a volume with constant conditions in the hydrological cycle. Microhydro Power Plant (PLTMH) is renewable energy that utilizes water resources as an energy producer where the energy produced is classified as small scale energy (less than 200 kW). Electrical energy is energy that is produced from changing other energy that has strength and capacity. Sustainable Development Goals (SDGs) are a new development agreement agreed upon at the UN general assembly in September 2015 with 17 goals to encourage changes towards sustainable development, one of which is regarding clean and affordable energy which is contained in point 7. The location of this research is to determine the potential and estimate the availability of energy to fulfill electricity needs in Rantau Kermas Village,ANGKAt District, Merangin Regency, Jambi Province.

Abstract

The presence of lava and pyroclastic sequences in the Karing River on the Merangin Jambi UNESCO Global Geopark territory provides information about the existence of ancient volcanoes. The absence of confirmed rock formations from the distribution of volcanic rock products that have been mapped nationally and also the shape of this ancient volcanic body, is an important reason for this research to be carried out using a petrological approach using petrography and XRF gochemical methods. Petrographic analysis is an appropriate method to determine the mineralogy consist, textures and particular textures, rock structures that are confirmed from field data. Meanwhile, a geochemical approach is used to determine rock oxide compounds. This method aims to reconstruct the shape and type of volcanoes. Research data shows that there are four lava sequences, with Sequence 1 having an entablature structure, Sequence 2 and Sequence 3 having a flow structure, and Sequence 4 having a vesicular-flow structure. The petrography results show that Sequence 1 and Sequence 2 are composed of phenocrysts and microliths of plagioclase, olivine, clinopyroxene, orthopyroxene. Meanwhile, in Sequence 3, hornblende is present, and in Sequence 4, the mineral olivine is absent. The results of geochemical analysis from the four lava sequences are in basalt rocks with 40%-50% Silica content, Calk-alkali basalt magma series, petrogenesis interpreted from the convergence of oceanic subduction beneath continent. The pyroclastic rocks found at the bottom of the lava sequence are evidence of the stratigraphic structure that makes up a volcano originating from the Karing Paleovolcanic, while the pyroclastic rocks found at the top of the lava sequence are believed to originate from other ancient volcanic eruptions. With the stratigraphy composed of lava and pyroclastic sequences, it can be concluded that this ancient volcano is a strato volcano type which is relatively sloping and almost resembles a shield volcano.

Abstract

Research has been conducted using the ground penetrating radar (GPR) method which aims to determine subsurface lithology on peatlands in Jati Mulyo Village based on 2D modeling. The GPR method is one of the geophysical methods that applies electromagnetic wave propagation. GPR data measurements were carried out as many as 3 passes with each length of 200 meters. The result of the GPR measurement is a 2D model that describes subsurface lithology. The response of this 2D model is in the form of a distribution of color variations starting from yellow-red, green, light blue -dark blue. The yellow-orange color response indicates the presence of minerals found on peatlands. The green response describes the soil below the surface. While the blue response indicates a cavity filled with water. This is appropriate based on the geology of this peatland is a sedimentary deposit that has pores filled with water and the presence of mineral content contained in the peat soil.

Abstract

Hydroxyapatite (HAp) biomaterials have been successfully obtained from Channa striata and Scomberomorus commerso fish bone. Heat treatment was chosen as the method to get it. Heat treatment was done at 400oC, 600oC, and 800oC. The X-ray diffractometer (XRD) was used to determine the crystalline phase and crystallography properties. Based on XRD data and JCPDS 09-0432, all samples showed the phase of HAp. However, the β-TCP phase has been found in samples from Scomberomorus commerso, which calcined at 600oC and 800oC. The crystallite size of HAp from Channa striata fish bone increased as followed by higher temperature, and Scomberomorus commerso has the same crystallite size on samples that calcined at 600oC and 800oC. The microstrain of both samples has the same trend: the higher the temperature, the lower the microstrain. The temperature also affected the crystallinity sample; the higher the calcined temperature, the improved crystallinity. Fourier Transform Infrared (FTIR) data determined the functional groups of samples. The functional groups that appeared were OH-, PO43-, and CO32-. The mass of samples before calcined differs from after calcined, where the mass after calcined is smaller than before. The higher the temperature we used, the more decreased yield percentage we got.

Abstract

Research has been carried out to carry out soil vulnerability analysis at the Faculty of Science and Technology, Jambi University. The construction of buildings at the Faculty of Science and Technology has necessitated an analysis of the vulnerability of the land around the buildings at the Faculty of Science and Technology. Based on the regional geology in this area, the Muara Enim formation (TMPM) is formed in the Tertiary age which is composed of rocks from interbedded tuffaced sandstones with tuffaced mudstones, interbedded quartz sandstones with quartz mudstones, interbedded with coal and iron oxide. The rocks formed in this formation are a type of sedimentary rock. To carry out soil vulnerability analysis, the HVSR method is applied to measure microtremors. Microtremors are a geophysical method that uses very small and continuous ground vibrations. This HVSR method is a passive seismic method using three components, namely 2 horizontal components and 1 vertical component. Microtremor measurements on the ground were carried out at 6 points around the building. The results obtained from microtremor measurements using the HVSR method are the natural frequency (f0), amplification factor (A0) and Seismic Vulnerability Index (Kg). The natural frequency (f0) value ranges from 1.30-1.82 Hz, the amplification factor (A0) value ranges from 1.69 - 3.28 times and the seismic vulnerability index (kg) value ranges from 1.814167 to 5.948834 x 10^-6 s^2/cm. Based on the Kanai classification, a frequency value < 2.5 HZ includes soil type IV and soil type II with Alluvial Rock lithology formed from delta sedimentation, top soil, mud. With a depth of 30 meters or more. This area has a very thick surface sediment, more than 30 meters. Based on the classification according to Setiawan, the amlification factor is classified as low (A0<3) to medium (3<A0<6). A low to moderate amplification factor indicates that the rock that makes it up is compact/hard. Based on the Refrizon Classification, the Seismic Vulnerability Index value is in the low (kg<3) to medium (3<kg<6) category. The seismic vulnerability index is low to medium, meaning that if a shock occurs there will be no damage because the vulnerability value is medium - low. Based on these three parameters, it can be concluded that the land around the FST building is still classified as safe from shocks.

Abstract

A research has been conducted to help the medical staff in the hospital. The purpose of this study is to calculate and regulate the infusion flow rate of the infusion into the patient's body. This research uses an experimental method. The liquid released from the infusion is converted into droplets, which are then detected by the LM393 optocoupler sensor, which consists of three sensors arranged around the detection area by emitting infrared light through a transmitter to detect the shadow of the droplet so that the signal is received by the receiver of the optocoupler sensor. Which is processed with the Arduino Uno microcontroller. The Arduino Uno provides the results received from the sensor and coded using the Arduino IDE software to be displayed on a 16x2-character Liquid Crystal Display (LCD). The sample used in this study was Sodium Chloride (NaCl). The calibration tools performed were droplet sensor test, servo motor test, and Real Time Clock (RTC) DS3231 module test. The results of the detection in the droplet sensor configuration showed a high degree of accuracy, with an error value of 2.414%. so that this research can be implemented in the detection and appropriate management of infusion flow rates. The current testing being carried out is still on a laboratory scale. However, in the future, this system can be developed to monitor infusions in real-time over a longer period of time and using more complex data processing functions.

Abstract

Waduk merupakan suatu bangunan buatan yang berfungsi untuk menampung air. Penyebab utama yang dapat menyebabkan kerusakan pada badan tanggul biasanya adalah keruntuhan tanggul yang disebabkan oleh ketidakstabilan tanggul tersebut. Ketidakstabilan tanggul dapat terjadi karena adanya rembesan air yang menyebabkan tanah menjadi jenuh air. Tanggul Waduk Desa Kemuja hingga saat ini terdapat beberapa retakan pada badan tanggul yang kemungkinan dapat menyebabkan keruntuhan tanggul apabila tidak ditangani lebih lanjut. Penelitian ini mengidentifikasi kondisi lapisan tanah pada tanggul agar dapat mengetahui ketidakstabilan tanggul Waduk di Desa Kemuja menggunakan metode geolistrik self-potential (SP). Penelitian ini dilakukan dengan mengukur 3 lintasan penelitian. Berdasarkan hasil penelitian, pada lintasan 1 terdapat ketidakstabilan tanggul pada jarak 110 m dengan nilai potensial sebesar -11,1 mV dan pada jarak 125 m sebesar -10,8 mV, pada lintasan 2 terdapat pada jarak 155 m sebesar -1,3 mV, dan pada lintasan 3 terdapat pada jarak 55 m sebesar -4,1 mV. Ketidakstabilan tanggul menunjukan anomali negatif ketika rembesan air masuk ke tanggul. Zona ini dapat menyebabkan keruntuhan sehingga dapat mengganggu kestabilan tanggul. Berdasarkan hasil yang diperoleh, dapat disimpulkan bahwa metode self-potential (SP) dapat digunakan sebagai solusi tercepat untuk mencegah kerusakan tanggul berdasarkan identifikasi ketidakstabilan tanggul.
