Membuat Sistem Informasi (Kehutanan)

Saya cukup sering mendengar institusi-institusi menganggarkan pembuatan Sistem Informasi semisal Sistem Informasi Manajemen Kehutanan (SIMHUT), Sistem Informas Lingkungan, dan lain sebagainya yang kebanyakan ujung-ujungnya adalah website. Apakah membangun sistem informasi itu produknya adalah website? Atau itu hanya sarana untuk gaya-gaya an saja biar kelihatan wah. Tidak punya website ya ketinggalan jaman.

Saya mengamati bahwa ada beberapa kesalahan dalam mendisain dan menjalankan Sistem Informasi dalam institusi sebagai berikut. Continue reading “Membuat Sistem Informasi (Kehutanan)”

Weibull Parameter Estimation using Linear Regression

Weibull statistic is the most favorite model of mine. Not only its flexibility to mimic many natural phenomenon, it also has plenty of methods (approaches) in predicting its parameters. Yes, I do like the choices of Weibull in deciding which parameter estimation method suits with my application. In this writing, I want to show the example of Linear Regression method in predicting 2-parameters Weibull distribution. Other methods such as Maximum Likelihood or Percentile will be discussed later on. Continue reading “Weibull Parameter Estimation using Linear Regression”

Map Scale

Some definitions of map scale
“the ratio of the distance on a map to the corresponding distance on the surface the map represents”
“Map scale is the relationship between a unit of length on a map and the corresponding length on the ground. It’s also expression of how much the area represented has been reduced on the map”
“Map scale specifies the amount of reduction between the real world and its graphic representation (usually a paper map).
“The scale of a map is the ratio of a single unit of distance on the map to the equivalent distance on the ground”
“Map scale represents the ratio of a distance on the map to the actual distance on the ground”
