Semi-infinite slab modeling has been made through inverse data gravity using Matlab. Inversion of gravity data is done by first determining the simulation data. Forward modeling uses simulation data to produce an initial guess inversion model expressed with parameters n0 (1), n0 (2), n0 (3) and n0 (4). The forward modeling is performed on the next initial guess that the value of the misfit is as small as possible through an iteration using the Jacobian matrix. Accuracy of inversion results is determined by the initial guess and the number of iterations. The results obtained show that inversion modeling is more valid in the inversion modeling process compared to advanced modeling, because the value of the parameters sought is generated from mathematical observations of the observation data. Guesses greatly affect the results of inversions obtained. Initial guesses are given in the form of parameters n0 (1), n0 (2), n0 (3) and n0 (4). The initial guess for the parameters n0 (1), and n0 (2) that are made far deviant does not affect inversion. The initial guess for the parameters n0 (3), and n0 (4) that are made deviating far influences the inversion caused by a very small RCON value so that the result is NAN.

Online assessment has been carried out research on academic information system Unnes using Technology Acceptance Model (TAM) whose goal is to achieve accountability in academic application by taking the Graduate Program Unnes sampling. The method used to carry out this research through interviews/in dept interviews, documentation and questionnaires. Analyses were performed using analysis of Structural Equation Modeling (SEM) based covariance AMOS (Analysis of Moment Structures). The results obtained overall, Knowledge of Search Domain has no effect on Perceived Ease of Use. However, CMIN / DF qualified, because it has a value of≤2.

Salah satu jalur penjaringan mahasiswa baru Universitas Negeri Semarang (UNNES) adalah melalui Seleksi Nasional Masuk Perguruan Tinggi Negeri (SNMPTN). Mekanisme seleksi melalui SNMPTN didesain dengan berbagai kemudahan karena berbasis laman yaitu melalui http://penerimaan.unnes.ac.id. Terdapat fenomena yang menarik terkait dengan kecenderungan jumlah pendaftar mahasiswa baru UNNES yang perlu diteliti menyangkut usability laman http://penerimaan.unnes.ac.id/. Hasil analisis data peminat SNMPTN dan SPMU UNNES selama lima periode terakhir terhadap jumlah mahasiswa yang diterima memperlihatkan jumlah penerimaan mahasiswa UNNES lebih besar berasal dari peminat SPMU dibandingkan dengan peminat SNMPTN. Hal tersebut menunjukkan usability laman http://penerimaan.unnes.ac.id/ optimal.

This service aims to provide assistance to the community in the Gubung Serut area to prepare educational natural tourist destinations. Mentoring involves partners from PT. Astra International Tbk., Honda Central Java region. Community empowerment applies a participatory method through the stages of community empowerment through the stages of preparation, implementation, and evaluation. Preparation is carried out through the stages of establishing partnerships to build a shared commitment to developing empowerment programs in target locations. The empowerment program is prepared jointly between the service team, village officials, and target community leaders. Data during the empowerment process and activity achievements were collected through interviews and observations. Interviews reveal the opinion of tourism managers about knowledge gained during empowerment activities and benefits obtained in setting up educational tourism areas. The number of visitors to the tourist area every week has reached more than 100 people. The most attractive tourist destinations for visitors are natural panoramas and educational attractions. Preparing the Gubung Serut tourist area to become an educative natural tourism destination has been carried out through preparing management resources, building destinations, and preparing educational tourist attractions. The development of the Gubung Serut tourist area needs to be done with a broader partnership. The culinary and artistic potential still needs to involve partners more broadly to increase the diversity of tourist attractions that attract visitors.

Studi literatur untuk mengestimasi temperature reservoir Gunung Lumpur Bledug Kuwu telah dilakukan menggunakan metode geotermometri larutan. Perhitungan temperature diperoleh dari hasil perhitungan empiris kandungan unsure-unsur kimia terlarut pada air panas Gunung Lumpur Bledug Kuwu. Kandungan unsure ini diperoleh dari hasil analisis sampel air panas dengan metode Atomic Absorption Spectrophotometer (AAS) yang dilakukan oleh Rizqiya 2014, berupa konsentrasi Na, K, Ca, Mg dan SiO2. Dari hasil perhitungan ini, estimasi temperature reservoir Bledug Kuwu berkisar antara 90.411 – 148.354 0C.
