Abstract

Telah dilakukan penelitian tentang kerentanan tanah di Kecamatan Adipala, Kabupaten Cilacap, menggunakan  data  rekaman  mikrotremor  untuk  dianalisa  menggunakan  metode  Horizontal  to vertical Spectral Ratio (HVSR). Metode ini digunakan untuk mengetahui nilai frekuensi dominan tanah  (f0)  dan  amplitudo  dari  frekuensi  dominan  tersebut  (A0).  Nilai  f0  dan  A0  yang  diperoleh selanjutnya akan digunakan lagi untuk menghitung nilai kerentanan tanah (Kg) yang berkaitan dengan kemampuan atau ketahanan tanah terhadap gempa. Dari hasil penelitian yang mengambil 17 titik pengambilan data diperoleh bahwa Kecamatan Adipala memiliki nilai amplifikasi tanah antara 1-8 dan merupakan kawasan dengan resiko kerusakan tinggi apabila terjadi gempa.

Abstract

Geothermal prospect in Cipari has been shown by spring who has a temperature of about 50°C and is categorized as a low temperature. The presence of spring on Cipari earth's surface is an indication of geothermal structures' existence on the surface and a geothermal system below the surface. Geophysical methods can be used for subsurface structures identification, one of them is the density method with gravity data. This study has an objective to identify the subsurface structures in Cipari geothermal potential area using GGMPlus gravity data. Terrain and Bouguer corrections were used to obtain Complete Bouguer Anomaly (CBA). Separation of regional and residual anomalies using Butterwoth and Bandpass filters. The rock contact boundary was obtained by the FHD method and geological structures such as faults were obtained by the SVD method. FHD and SVD results were used as information for 2D forward modeling. The ABL map shows anomalous contrasts in areas that have rock contacts and geological faults. The high anomaly in the center of the study area indicates the Cipari anticline. Data processing and analysis concluded that the area around the Cipari hot spring has anticline, several rock contacts, and normal fault structures. The fault in the study area is part of the geothermal system which is confirmed by GGMPlus data.

Abstract

Lumajang is one of district at Jawa Timur regency where located Lamongan volcanic area. Lamongan volcano is a young monogenetic volcano that was growth from a fault at the summit. Eruption at Lamongan volcano not only occurred at the main volcano, but also at parasite cone at Lamongan volcanic area with 37 cinder cones dan 27 maars. Cinder cones dan maars formed from contact of magma and water that cause freatomagmatic eruption with pyroclastic debris and material deposit’s flow. This research focused at mapping western Lamongan volcanic area based on magnetic anomalies to conducted vulcanic activities at subsurface. Based on magnetic anomalies data, there is an area at south, west, and north with high temperature subsurface rock around maars and cinder cones, that is indicated by negative magnetic anomaly. Keywords: Lamongan volcano, maar, cinder cone, magnetic anomalies.

Abstract

Jeruklegi landfill has leachate management system that still potential for leachate infiltration in subsurface. Leachate contamination may occur if landfill activity is continuous and have an impact to local society. Leachate contamination is an environmental pollution man-made minor disaster clasified. This research is an early prevention step by identifying disaster source. Identification is done by analyzing leachate distribution in subsurface using geoelectrical method with Wenner-Schlumberger array. The result of data acquisition is resistivity which is processed to apparent resistivity. Apparent resistivity was modelled by inversion method that shows leachate contamination near surface by resistivity not least at 1 ohm.m. Leachate contamination was not found over 20 meters based on the lack of resistivity difference. This was confirmed by chemical test of bore well water that match to hygiene and sanitation standards. Keywords: leachate, resistivity, geoelectric, Wenner-Schlumberger.

Abstract

The Use Of Mobile Technology In The Industrial 4.0 Era Is A Must. The Number Of Smartphone Users Continues To Increase Over Time. Contiinum Reality Technology Which Consists Of Both Virtual Reality (VR) And Augmented Reality (AR) Becomes A Portable Technology That Is Easy And Affordable Being Used With A Smartphone. This Study Has An Objective To Determine The Potential Uses Of Augmented Reality (AR) Technology In Modern Islamic Da'wa. This Study Are Counted As A Literature Study Using The Traditional Review Method.AR Applications Have Been Used In Many Fields, Such As Medical, Military, Manufacturing, Visualization, Entertainment And Games, Robotics, Education, Marketing, Navigation, Tourism, Geospatial, Urban Planning And Civil Sciences. Da’wa Requires Attention In Both Truth And Good Ability Of The Preachers. It’s Based On Legal Aspects And The Procedures (Fiqhud-Dakwah). There Was Limited Amount Of Research And AR Products Used In Da'wa. The AR’s Technology That Can Be Applied In Islamic Da'wa Are 1) Playing Cards For Da’wa, 2) Islamic Story Books, 3) Da’wa Brochures / Leaflets / Poster, 4) Islamic History Museum.

Abstract

This research develops a Microsoft Excel application based on the Visual Basic for Application (VBA) Assessment Matrix of 9 Standard Bachelor Programs with product advantages. They are a matrix display with simpler sentences, accreditation assessment, a dashboard of assessment results, and an information system following LKPS to facilitate the manufacture of LEDs based on Quadrant Evaluation. The 4-D development design method is carried out through 4 stages: define, design, develop, and dissemination. The defined stage includes an analysis of the needs of study program managers facing accreditation, an assessment matrix of 9 standard study programs, and dashboard analysis. The design stage includes the selection of the calculation format, dashboard format, and the initial design of the Excel program (prototype I). The development stage is the validation of the initial product design, with the results of the assessment of the content aspect being 4,6250 valid criteria, displaying 4,3750 valid criteria and 4,1250 valid criteria for programmers (prototype II). Limited trials were carried out on all members of SPMI UNUGHA. Each item scored more than or equal to 3.75, with an average of 4.3276, which means it is feasible with a very good rating. (prototype III). The first year the field trial was conducted at the Nahdlatul Ulama University Mathematics Study Program, Purwokerto. Each item scored more than or equal to 3.75, with an average of 4.1354, which means it is feasible with a very good rating. (prototype IV). The dissemination stage (prototype 4) is carried out in two forms: scientific publications in SINTA accredited national journals (INSANIA: Journal of Alternative Educational Thought) and intellectual works: Microsoft Excel applications based on Visual Basic for Application (VBA) Undergraduate Program Assessment Matrix 9 Standards.

Abstract

MTs Sultan Agung Kalipoh in Kebumen Regency is one of the junior high schools that established a content creator community since 2021. However, despite having computer laboratory facilities, those students primarily relied on smartphone applications indicating basic graphic design knowledge level within their community. Therefore, it is necessary to enhance their creativity and computer-based graphic design skills through learning how to design logo using CorelDraw and Photoshop in form of case study. The community service program was conducted in four (4) phases: analysis of situation, formulation of possible solutions, logo creation training, and evaluation. The results showed a notable 59% increase in logo creation experience indicating of the enhanced creativity in graphic skills. Moreover, there was an 80% improvement in knowledge regarding graphic application functions, and a 75% improvement in the ability to create logos.
