Abstract

Distribusi log-logistik merupakan salah satu distribusi yang dapat diaplikasikan untuk data mutu lingkungan. Makalah ini membahas pembangkitan data dari distribusi log-logistik mulai dari pembangunan algoritme sampai pembuatan program komputer pada perangkat lunak MATLAB. Metode pembangkitan datanya menggunakan metode inverse transform. Ada dua jenis data yang dibangkitkan, yaitu data lengkap dan data tersensor kiri. Dalam makalah ini diberikan contoh data yang dibangkitkan dari distribusi log-logistik.

Abstract

Model variasi komponen H medan magnet bumi menggunakan Analisis Deret Fourier, berdasarkan data pengamatangeomagnet dari stasiun pengamat geomagnet LAPAN biak, pada aktivitas matahari minimum. Pemodelan variasi komponen Hmedan magnet bumi ini diawali dengan penentuan periodisitas gangguan yang mempengaruhi aktivitas geomagnet,menggunakan fast Fourier transform (FFT). Dari hasil analisis diperoleh periodisitas ganguan yang mempengaruhi medanmagnetbumi terdiri dari periode 24, 48 dan 72 jam. Antara periode-periode gangguan tersebut yang paling dominan adalah periode 24jam dan periode inilah yang mendukung pemodelan variasi komponen H medan magnet bumi pada aktivitas matahari minimum.Akurasi model dinyatakan galat sebesar 7,36 nano tesla dan kesamaan pola antara data pengamatan terhadap model dinyatakandua versi koefisien korelasi yaitu R2 = 0,883 menurut pola linear dan R2 = 0,916 dalam bentuk pola logarithmik

Abstract

Data transformation plays a major role when behave of the data do not meet the assumption of linearregression and ANOVA. In this paper we will demonstrate an application of the alternative method oftransformation, so that the assumptions of ANOVA are met (or violated to a lesser degree). These datawere collected from biostatistics experiments. Some of calculation is done by manually and the restby the MINITAB software. The results will be discussed at the end of the paper.

Abstract

The act of violence against wife is condemnable and attracts various legal penalties, globally. This article attempts to find a link between spousal age difference and violence (Emotional, Physical and Sexual) against wives in Nigeria. The result show that wives who are older than their partners are more likely to experience sexual and emotional violence; also, wives who are same age as their husbands are more likely to experience sexual violence; whereas wives who are 1-4 years younger than their husbands are more likely to experience physical violence; while wives 5 years or more younger than their husbands are generally less likely to experience any form of violence.

Abstract

Pengukuran dari sebuah karakteristik menghasikan sebuah nilai yang berbeda beberapaderajat dari nilai sebenarnya. Perbedaan ini disebabkan adanya kesalahan pengukuran karenabeberapa sumber variabel yang berhubungan dengan proses pengukuran. Penilaian terhadapsumber-sumber kesalahan pengukuran mempunyai peranan penting dalam menentukankemampuan suatu alat ukur. Penilaian tersebut diantaranya diukur dengan Repeatability danReproducibility. Pada makalah ini akan dibandingkan perhitungan nilai varians Repeatability danReproducibility melalui dua metoda yaitu metoda Anava dan metoda Varians Sampel denganmenggunakan simulasi “Monte Carlo”

Abstract

Dalam penelitian, peneliti tidak terlepas dengan data. Untuk keperluan analisis, ada ketentuanbahwa asumsi dari data yang dipergunakan haruslah mengikuti distribusi normal. Salah satumetode untuk kecocokan distribusi normal, dapat menggunakan Plot Persentil-Persentil atau P-PPlots yang distandarisasi (F.F. Gan, Kennet J. Koehler and John C. Thompsons; 1991).

Abstract

Deforestation and forest degradation caused by mining has had very great impact to global climatechange, because one of the functions of forest vegetation is very important is capture and storageCO2 emissions. Revegetation activities in the area of mining is done in order to restore the forestvegetation. Research to estimate absorbtion CO2 as a result of carbon stock by forest vegetationneeds to be done . Remote sensing technology through radar imagery can be applied to estimateforest vegetation carbon stock more quickly and efficient. The research was conducted in the goldmining area of PT . JResources Bolaang Mongondow. Main objective of this research is to estimatechanges in forest covered land due to mining activities, estimation amount of carbon stored in 2008 ,2009, and 2010 and the economic value that can be obtained from stored carbon, using theestimated price based REDD schemes. The methodologies for measurements of the variables used inthe calculation variable of above ground biomass using allometric and ALOS PALSAR image analysisof 2008, 2009, and 2010 to estimate the carbon stock in forests. The results showed there werewidespread changes in forest land cover due to mining activities, and based on image analysis of2008 , 2009, and 2010 , the amount of carbon stock in the research area respectively are32,695,253.57 ton C, ton C 50,146,772.71 and 79,420,248.55 ton C. The economic value of carbonstock in 2010 are Rp.7,538,299,190,029.09 with price estimates and assumptions based on REDDscheme BAU Carbon savings in 2008.
