Abstract

Good local government performance, especially related to the realization of good corporate governance, can be created if there is good communication between agencies, employees and compact collaboration to synergize policies that facilitate public services. To optimize government performance, one of which is the Boyolali District Archives and Library Service through collaborative relationships between employees so as to create intense two-way communication. This study aims to identify social networks related to collaboration between employees using the Social Network Analysis method and a total of 40 people as respondents, but only 32 people filled out the questionnaire data completely. The indicators used in viewing the research results are density values, degree centrality values, closeness centrality values, betweenness centrality values, and clique values. The results of the analysis obtained a network density level of 14.8% (considered weak because it is less than 50 percent). Employee number 21 has the highest degree centrality value and betweenness centrality value, then employee number 9 has the highest closeness centrality. This research concludes that there is a good collaborative relationship between the four departments in the Archives and Library Office of Boyolali Regency, namely the Operations department, the Service department, the Archives department, and the Librarian department.

Abstract

The case of drop out at the Weleri STEKOM is often done by the campus. Drop out is a problem that is often done by Weleri STEKOM students because of a GPA of less than 2, Number of organizations followed, Tuition not paid for students and student who have exceeded the limit of 14 semesters. This study discusses predicting drop out students with C4.5 and ID3 decision tree methods that are useful to assist the campus in anticipating student dropouts. This study uses student data as many as 1087 students. Student data is divided into training data and testing data in order to obtain a model or rule in predicting DO students. Variable of this reseach contain V1(GPA) and then V2 (Distance beetween home and campus), V3(how long the lecture has been done), V4(Having a Job), V5(Family) and V6(school fee). This   research  The results of this study obtained 18 rules or rules for ID3 algorithm and 8 rules for C4.5 algorithm. The algorithm ID3 test results obtained an average of 95.17%, precision of 94.7% and recall of 96.18%, while for Decision Tree C 4.5 obtained an average of 96.45%, precision of 96.90% and recall of 95.38. This research prove that Decision using C4.5 is better for prediction of drop out students at STEKOM.

Abstract

Kecamatan Bandungan dan Sumonowo merupakan wilayah di Kabupaten Semarang yang ditetapkan sebagai kawasan Agropolitan. Dalam beberapa survei dan penelitian di kawasan yang memiliki kesamaan administratif dan geografis tersebut menunjukan tren perubahan produktifitas pertanian akibat pembangunan. Pendekatan sistem informasi geografis digunakan dalam penelitian ini dengan alasan untuk bisa menganalisis objek spasial secara menyeluruh pada kawasan terkait. Penelitian ini berusaha memetakan penataan ruang secara objektif dengan metode Artificial Neural Network. Dimana hubungan antar objek spasial dikalkulasikan potensi perubahannya pada dua data spasial yang berbeda   tempo. Hasilnya didapatkan bahwa simulasi objektif dengan metode ANN terhadap data spasial hasil klasifikasi menggunakan metode minimum distance diperoleh min validation error 0,0656. Hasil validasinya juga cukup baik, yaitu memperoleh prosentasi kebenaran 85,3% dan index kappa 0.80. Peta simulasi dihasilkan sampai pada tempo 2021. Dari peta simulasi didapatkan pengetahuan bahwa sistem pertanian terbuka akan terus mengalami pertumbuhan luasan secara positif dengan kisaran 0,015%. Adapun sistem pertanian tertutup akan terus mengalami penyusutan luasan pada kisaran 0,01%. Pengetahuan ini bisa menjadi alternaif solusi dalam mempertimbangkan implementasi rencana tata ruang dan wilayah pada kawasan terkait.
