Abstract

Salah satu permasalahan utama analisis jaringan pada sistem informasi geografis (SIG) adalah menentukan jalur terpendek antara dua lokasi dalam suatu jaringan. Meski terdapat beberapa metode untuk menyelesaikan permasalahan ini tetapi pencarian metode alternatif masih penting dilakukan. Penelitian ini menggunakan pendekatan metode optimasi metaheuristik koloni semut yang terinspirasi dari prilaku alamiah semut, untuk mencari jalur terpendek antara dua titik, pada data jaringan jalan riil (JJR). Pengujian terhadap metode ant colony optimization (ACO) dilakukan dalam dua tahap. Pertama, pengujian menggunakan data buatan untuk mendapatkan gambaran pengaturan terbaik dari parameter-parameter metode koloni semut. Kedua, pengujian menggunakan data JJR untuk melihat kinerja metode optimasi koloni semut terhadap data JJR. Hasil pengujian optimasi koloni semut pada data JJR kemudian dibandingkan dengan hasil pengujian algoritme jalur terpendek Dijkstra pada JJR dalam hal panjang jalur optimal dan waktu eksekusi. Hasil pengujian menunjukan bahwa secara secara umum metode Dijkstra menghasilkan solusi yang lebih baik dari metode ACO namun pada pengaturan parameter tertentu ACO lebih cepat dari Dijkstra.Kata Kunci: algoritme Dijkstra, analisis jaringan, jaringan jalan riil, optimasi koloni semut, permasalahan jalur terpendek.

Abstract

AbstractThe purpose of this research is to know the author's productivity pattern of article in the field of agriculture in Indonesia 2006-2015 using Lotka’s Law. The data of this research were taken from national journal accredited by the Ministry of Research, Technology and Higher Education which can be accessed from http://www.kopertis12.or.id. From 2006-2015, it is found that there are 2650 authors and 4141 articles on Agriculture. Assessment author’s participation was done by using ‘straight count’.The Lotka theoretical value use the formula of yx=C/xn.. C is a constant and n is exponent. Based on the calculation with Lotka’s law, it is found that C=0.80773 and n= 2.81500. The result shows that the percentage of the authors giving contribution to 1 article is 80.77%. Test of Kolmogorov-Smirnov results shows that the maximum deviation is 0.08396 with critical value (with α = 0.05) 0.02642, it shows that the maximum deviation is bigger than critical value. Therefore, the null hypothesis is rejected and concluded that the dataset does not follow Lotka’s law (there is a significant difference between the Lotka’s law theoretic distribution and the distribution of article author in the field of Agriculture). Keywords: Agriculture Science, Author Productivity, Bibliometrics, Lotka Law

Abstract

Indonesia has the largest peatland area among tropical countries, covering about 21 milions ha, which spread mainly in Sumatera, Kalimantan, and Papua. Land and forest fires occur almost every year in peatland areas in Indonesia. One of indicators for forest and land fires is hotspot. The objective of this study is to group hotspots with road and river as obstacles using the CPO-WCC (Clustering in Presence of Obstacles with Computed number of Cells) algorithm. Clusters of hotspot data were analyzed based on peatland area distribution. This study also evaluates the results of clustering on peatlands in order to obtain the best clusters. Clustering using CPO-WCC algorithm produces three clusters of hotspot. The area of dense cluster is 10202.10 km2 with number of hotspots per km2 is 0.985. The higest number of hotspots occurrence is found in peatland with type of Hemists /Saprists (60/40) and depth greater than 400 cm.

Abstract

The quality of a university is not only measured by its academic program inputs but also by its processes, outputs, and outcomes. Performance measurement can be conducted by looking at its achievements at a certain period of time compared with its targets and baseline. It is a fact that the academic implementation of the Undergraduate Program of Computer Science of Faculty of Mathematics and Natural Science IPB is unsatisfactory viewed from the average GPA and study duration during the academic years of 2009-2013. This study aims to to describe the quality of the implementation of the Undergraduate Program of Computer Science and the efforts made by the stakeholders in maintaining and improving the quality and to formulate alternative strategies to obtain better quality. Fishbone analysis method was used to determine the cause of an unsatisfactory average GPA and longer study duration, and descriptive analysis was used to describe the academic quality of the undergraduate program of Computer Science. The results showed the academic quality of the academic year of 2009-2013 has not reached the targets set in the strategic plan, but if seen from the figures, its accomplishments have nearly reached the targets; therefore, it can be said the quality is reasonably good. Constructive efforts in running the academic administration of the study program have also been implemented by the management.Keywords: academic quality, period of study, quality improvement, FMIPA IPB
