Abstract

The technology and sophistication of social media is growing very fast, marketing is increasingly growing in proportion to the information needs of the community. Therefore we need an appropriate strategy to deliver information well, and be able to achieve success. The purpose of this study was to help MTS Al-Husna YPIHN in an effort to focus on new prospective students. The problem that occurs in marketing MTS Al-Husna YPIHN is the lack of effective media in delivering messages. The marketing used is only using a brochure, brochures and there is no media video profile that explains in full about the school profile, excellence, vision, mission, school achievements and school facilities. The method used is the method of data collection (Observation, Interview, Library Study) and the method of the Concept of Media Production (KPM). The results of this study were in the form of Vidio Profile of the MTS Al-Husna YPIHN school, which included all school profiles designed using Adobe Premier Pro and Adobe Photoshop software. Through the design of promotional media using this video profile will increase the interest of new prospective students to join MTS Al-Husna YPIHN every year and can be useful as a medium of information for the community.

Abstract

Sebagian wilayah pantai Kota Pekalongan dijumpai adanya air tanah payau yang pelamparannya semakin luas. Tujuan penelitian ini adalah untuk memetakan sebaran air tanah payau tersebut, baik pada akuifer dangkal maupun akuifer dalam dan juga untuk mengetahui penyebab keasinan air tanah tersebut. Sebaran air tanah asin dipetal<an berdasarkan nilai daya hantar listrik (DHL) dengan kriteria tingkat keasinan sebagaimana ditetapkan oleh Panitia Ad Hoc Intrusi Air Asin Jakarta. Sedangkan penyebab keasinan air tanah dianalisa berdasarkan fasies hidrokimia dengan diangram Trilinier Piper. Hasil penelitian menunjukan bahwa pada akuifer dangkal air tanah agak payau dengan DHL 1500 \iS/cm - 2.200 uS/cm dijumpai di sebelah utara, meliputi Desa Bandengan, Kandang Panjang, Panjang Wetan, Krapyak Lor, dan sebagian Degayu. Sedangkan untuk airtanah dalam seluruhnya dalam kondisi tawar dengan nilai DHL < 1500 uS/cm, kecuali sumur di Pantai Sari tergolong agak payau dengan DHL 1.602 jjS/cm. Keasinan air tanah pada akuifer dangkal disebabkan oleh proses intrusi air laut, kecuali air tanah di Kauman merupakan air fosil (connate water). Untuk akifer dalam juga tampak mulai muncul tanda-tanda intrusi air laut terutama pada wilayah bagian barat dan tengah, sedangkan di wilayah timur belum tampak adanya gejala intrusi air lautKata kunci: Daya hantar listrik, Intrusi air laut, akuiferIn the part of Pekalongan coastal region was found brackish groundwater which spreading progressively. Theaim of this research was to map the brackish groundwater, either at the shallow or deep aquifer and also toknow cause of the ground water saltiness. Briny groundwater spread was mapped based on the value ofelectric conductivity (EC) with saltiness criterion as specified by Panitia Ad Hoc Intrusi Air Asin Jakarta.

Abstract

Research of magnetic methods that aim to interpretation the subsurface structure around the hot springs area Diwak and Derekan and to identification caused of hot springs Diwak and Derekan has been successfully carried out. In this research, measurements were taken at 97 points using a proton precession magnetometer (PPM) type of GSM model 19T geometrics and two Geotron Magnetometer G5 models to get the value of the total magnetic field. Measurement data is processed by the daily variation correction and correction IGRF (International Geomagnetic Reference Field) to get the value of the total magnetic field anomaly. Corrected data used to create contours of the total magnetic field anomaly. Contour total magnetic field anomaly is used for the reduction to plan surface process and upward continuation process. The results of the upward continuation get the contours of local anomaly and regional anomaly, the results of the local anomaly contour then reduced to the pole. Results of the research is a pair of positive and negative closure indicate a fault structure below the surface. There are two pairs of positive and negative closure which an incision is made to determine the subsurface structure by creating a 2D model using the software Mag2dc. 2D modeling results indicate the existence of a second incision fault structure in the form of down trending fault southwest-northeast. Meanwhile, to make 3D models using software Mag3D and 3D modeling results indicate the presence of fault structures below the surface. Fault zone results of 2D and 3D modeling is a media outlet fluid to the surface in the form of hot springs Diwak and Derekan.
