Abstract

Water is an essential resource for human being and the needs significantly increases from time to time. The highly demand of water may cause water scarcity. Based on that condition, groundwater exploration is urgently needed, where at least the location and depth of the groundwater can be identified through an accurate method. Geoelectric, on the other hand, is a geophysics method that is commonly used for identifying geology structures, including for groundwater exploration or identification. The objectivity of this research was to compare the geoelectric configuration accuracy, which Schlumberger, Wenner, Wenner-Schlumberger, Dipole-dipole, and Pole-pole were discussed. As a result, configuration of Wenner amd Wenner-Schlumberger showed the best results based on the vertical resolutiuon, the CST, and the sounding parameters.

Abstract

Scattering of rocks can be done in various ways depending on the characteristics of the rock to be crushed. Blasting activities aim to remove or scatter material from the parent rock so that the size of the resulting fragmentation can facilitate further mining activities. The data used in this study is primary data. blasting geometry needs to modify the spacing because it affects the size of the rock, using a small level of space density will get a smaller rock size and reduce the number of rock boulders or bolder. The results of blasting 1 - 3 are calculated directly after blasting using the screening method with a size of 5 x 5 meters, the rock size is <20 cm = 22.60 percent, 21-40 cm = 25.34 percent, 41-60 cm = 28.08 percent, 61-80 cm = 22.60 percent, and 80 > cm = 1.37 percent. After accumulating the percentage, the size 0-60 = 76.03 percent, 61-80 cm = 23.97 percent, there are still 23.97 percent of rocks whose size is above 60 cm. The size of the retained rock is 61-80 cm = 23.97 percent, because the rock is still above 20 percent, it is necessary to destroy the rock using a mechanical method using a heavy rock breaker.

Abstract

Biodiesel, which is a methyl ester of fatty acids, has been considered as a renewable fuel that is environmentally friendly because it is able to support the sustainability of the carbon dioxide cycle. Biodiesel is conventionally synthesized from oil or fat with a homogeneous base catalyst, such as potassium hydroxide or sodium hydroxide. However, the use of homogeneous catalysts has several drawbacks, such as: it requires a tight free fatty acid content, is prone to oil saponification reactions, is relatively difficult to separate, and cannot be regenerated. Therefore, heterogeneous catalysts in biodiesel synthesis are considered as a substitute for homogeneous catalysts. Calcium oxide is a solid heterogeneous catalyst that has been proven effective in assisting the transesterification reaction of oil into biodiesel. Calcium oxide can be synthesized from calcium carbonate, which is widely found in waste, such as blood clam and egg shells. This study aims to synthesize and characterize calcium oxide from egg and crab shells as a catalyst in the synthesis of biodiesel from used cooking oil. Calcium oxide was obtained by calcination to blood clam and egg shells at 800 oC for 8 hours. The calcination results were further characterized by the method of x-ray diffraction and BET (Brunauer-Emmet-Teller) isotherm adsorption-desorption to determine the type of oxide phase formed and the surface characterization. The synthesis of biodiesel was carried out at a reaction time of 2 hours, a temperature of 60 oC, a molar ratio of oil to methanol 1:12, and a catalyst content of 10%. The results showed that calcium oxide was successfully synthesized from blood clam and egg shells waste with different characteristics. Calcium oxide from the two wastes is able to catalyze the transesterification reaction of used cooking oil into biodiesel, and biodiesel is produced according to SNI 7182-2015 concerning biodiesel quality standards.

Abstract

Picking is the process of moving an object while packaging is the process of packing the object. The development of industrial automation systems 4.0 allows both processes to be carried out using a Programmable Logic Controller (PLC) and robots. However, most industries in Indonesia are still using human labor. This method is considered less effective because human can feel tired and bored. This study aims to make the prototype of a picking and packaging system using PLC and robots. Robot 1 plays role in loading objects, robot 2 plays role in sorting, arranging, and packing objects, while robot 3 plays role in putting the lid on the packaging. System is made using 3 Dobot Magician robots, 3 conveyors, and 1 Outseal Nano V.4 PLC. System communicates with each other through an intermediary circuit using the PIC817 IC optocoupler. The results of the study experiment carried out showed that the system worked well and as desired, the system can move objects from the point where they placed, then sort objects by color to pack. Green objects will be packed while other colors will be returned. When the package is full, the system carries away it to be given the lid on the packaging

Abstract

The research focuses on dacite intrusion, in the Hargerejo area in the southern Kulonprogo Mountains and administratively in the Begelen District, Purworejo Regency, Central Java Province. The presence of a hydrothermal system in the Kulon Progo area is in the form of low-medium sulfidation epithermal in Kokap, Epithermal - Lithocap in Bagelen, and high-sulfidation epithermal in Menoreh (Magelang). In the case of the Bagelen intrusion, it is suspected that it is part of the hydrothermal system that forms the Au-Ag hydrothermal system. The research uses geological mapping methods and surface sampling on dacite rocks and laboratory observations with polarization and ore microscopy. This study focuses on the character of quartz and the presence of fluid inclusions by using the qualitative concept of fluid inclusion petrography. The lithology of the Bagelen area consists of volcanic breccias, andesite intrusions, dacites, and alluvial deposits. Petrographic analysis of dacite samples showed a porphyritic texture with 55-76% phenocrysts in the form of quartz (8-22%), hornblenda (3-11%), plagioclase (40-55%), surrounded by a bottom mass of volcanic glass and feldspar microlites. , as well as opaque minerals in the form of pyrite and residual magnetite as much as 2-5% and the base mass undergoes diagenesis and is changed to silica. Quartz is divided into types 1 and 2, indicating the presence of primary and pseudosecondary inclusion types. Quartz type 1 (qz-1) shows an irregular distribution and pseudosecondary trail with Type I, II, III inclusions. In type 2 quartz, it is seen that the inclusions are dominated by type II & III or L<V and L>V biphase, with low to high vapor densities. Inclusions in type 2 quartz show a primary pattern and are similar to the general epithermal vein fluid on the surface. The presence of fluid inclusions in the magmatic quartz at Bagelen, indicates the existence of a hydrothermal system formed due to changes in silicate character, and affects the fluid character from magmatic to hydrothermal. Epithermal or related mineralization is more influenced by the presence of type 2 quartz, and subsequent hydrothermal processes. The type of mineralization affected is intermediate sulfidation with a characteristic presence of disseminated pyrite-chalcopyrite in dacite. The fluid that affects mineralization is dominated by the epithermal system. Keyword : Exploration, Fluid, Copper, Gold, Kulon Progo
