Referensi2 June 23, 2023 3 minute read

Selama saya kuliah tentu saja banyak cari referensi, bahan, atau sekedar informasi di Internet. Ini adalah beberapa yang sempat saya simpan, dan daripada mengendap, apa ruginya kalo dishare? Berikut beberapa link penting yang bisa dimanfaatkan

Websites

  1. Home Page Omniscape
  2. Home Page Circuitscape
  3. Home Page MaxEnt
  4. NASA’s ARSET APPLIED REMOTE SENSING TRAINING PROGRAM Banyak training dan workshop yang bisa dijadikan bahan belajar
  5. NASA’s GIOVANNI Untuk visualisasi data satelitnya NASA. Bisa bikin mean klimatologi dari sini, bisa jadi alternatif kalo lagi males. Masalahnya kalo harus analisis yang lain, misal bikin standar deviasi klimatologi, gabisa pake... read more

Running Julia in the Cloud June 29, 2023 1 minute read

[ How To Run Julia in Cloud ]

Even tough julia was made to optimize hyper computation, often times the workload still surpass desktop computer capabilities. Once I tried running omniscape in a gaming pc with ryzen 9 5900x 16gb RAM, and the computation process still taking 80 days. To overcome this, I tried cloud computing services like Julia Hub, GCP, AWS, etc. I think this is the right solution because I can access much more powerful machine easily (If you have fine budget, there’s this 1TB RAM to up your game)

Time Elapsed inside a Grid Cell July 9, 2023 3 minute read

Time Elapsed inside a Grid Cell
Menghitung Waktu yang dihabiskan di dalam suatu grid cell.

Biasanya dilakukan dalam mengolah data tracking GPS. Hal ini juga sangat penting apabila ingin melakukan analisis dalam pergerakan hewan yang ditrack menggunakan GPS. Ada beberapa langkah yang bisa dilakukan:

Filtering

Filtering berguna untuk menghilangkan data-data yang error atau rusak. Contohnya seperti apabila hewan yang ditag adalah hewan aquatik, akan tetapi data yang diperoleh menunjukkan koordinat pada daratan. Ini merupakan suatu hal yang tidak mungkin, sehingga perlu dilakukan filtering atau menghilangkan data error tersebut. Contoh lainnya apabila ada pencatatan waktu yang sama dalam koordinat... read more

Bias June 23, 2023 2 minute read

Bias

A cognitive bias is a systematic pattern of deviation from norm or rationality in judgment.[1] Individuals create their own “subjective reality” from their perception of the input. An individual’s construction of reality, not the objective input, may dictate their behavior in the world. Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, and irrationality.

Pada perang dunia 2, para ilmuwan menganalisis bagaimana cara agar pesawat terbang bisa lebih kuat dan lebih aman bagi para pilot. Mereke kemudian mengamati bekas tembakan yang ada pada pesawat bomber yang kembali dari medan perang. Hasilnya adalah sebagai berikut: read more

Calculating Current Magnitude and Direction in R

Asumsi:
Data yang digunakan berformat tif, dan format nama file tifnya “u/v_angka bulan.tif” contoh “u_12.tif”,”v_3.tif”.
Dalam menghitung arah dan magnitude harus ada komponen U dan V.

library(raster) # Set the path to the directory containing u and v TIF files u_directory <- "D:/tes u v/u" v_directory <- "D:/tes u v/v" # Create empty lists to store monthly magnitude and direction monthly_magnitude_list <- read more
