Abstract

This study aims to map the level of animal food security in Indonesia using multidimensional scaling method. The data used are secondary data obtained from the Central Bureau of Statistics, namely the average data of consumption of animal protein (gram / capita / days) and the average data of consumption of animal protein (rupiah / capita / month) in 2015 from all provinces in Indonesia. The result of the research shows that group I is food resistant in all animal food commodities, namely West Sumatra, Riau, South Sumatera, Bangka Belitung Islands, Riau Islands, Banten, West Kalimantan, Central Kalimantan, South Kalimantan, East Kalimantan and North Kalimantan. Group II is food resistant in fish, eggs and milk, less food in the meat of North Sumatra, Bengkulu, West Nusa Tenggara, North Sulawesi, West Papua and Papua. Group III is food-resistant in meat, eggs and milk, lack of food in fish such as DKI Jakarta, West Java, DI Yogyakarta, and Bali. Group IV is food-resistant in eggs and milk, less food in fish and meat such as Lampung, Central Java, and East Java. Group V is food-resistant in eggs and milk, food-susceptible to fish, and less food for less meat, namely Aceh, Central Sulawesi, South Sulawesi, Southeast Sulawesi, Gorontalo and Maluku. Group VI status is susceptible to food in fish, less food in meat, eggs and milk of West Sulawesi and North Maluku. Group VII is under-food in all animal food commodities, namely East Nusa Tenggara. Stress value of 11.15% and R2 value of 95.01% indicate that multidimensional scaling method is suitable for use in this research. Keywords: animal protein, food security, multidimensional scaling method,

Abstract

Proses pemilihan feature dari citra RGB (Red-Green-Blue) dilakukan untuk memprediksi buah belimbing yang dicirikan dengan kandungan TPT (Total Padat Terlarut). Dari feature terpilih, dilakukan transformasi komponen utama satu dimensi (1D-PCA) dan dua dimensi (2D-PCA)  untuk mereduksi dimensi citra dengan proses pengenalan tingkat kemanisan yang dikelompokkan menjadi tiga, yaitu manis, sedang, dan asam. Dari 300 citra buah belimbing diperoleh hasil bahwa secara akurasi, teknik 1D-PCA maupun 2D-PCA memberikan  hasil  yang relatif  sama.  Namun  dari  segi kecepatan, 2DPCA jauh lebih cepat dibanding  1D-PCA, khususnya  pada  bagian  pembentukan  sumbu. Model hubungan  tingkat kemanisan sebagai fungsi dari  nilai RGB memberikan tingkat determinasi terbesarnya 69.9%. Percobaan  menunjukkan  bahwa 1D-PCA maupun 2DPCA mampu  menerangkan  sekitar  95% model hubungan tersebut yang dikembangkan pada ruang asal. Teknik PCA digabungkan dengan teknik klasifikasi KNN untuk pengenalan mampu mengenali buah kelompok manis dan asam dengan akurasi 100%. Sedangkan untuk kelompok sedang memiliki akurasi 83%.

Abstract

Mixture-mixture design with a split plot was proposed for simultaneously two mixture systems. The complete model was formed by multiplying cubic models for  two systems. The design was applied to the simultaneous optimizations of both mobile phase chromatographic mixtures and extraction mixture for the Phyllanthus niruri L. In this experiment used split plot approach. Saturated model coefficients were hypothesized with confident interval 99%. Reduction model consisted of real coefficients in complete coefficient models. Estimation method of reduction model coefficients consisted of Ordinary Least Square (OLS) and Generalized Least Square (GLS). Models were formed to count sum peaks chromatographic at 225, 254, and 260 nm. RMSEP values in OLS method at wavelength 225, 254, and 260 nm were produced 4.122, 3.049, and 2.56, otherwise RMSEP values in GLS method were 3.99, 2.79, and 3.18. There are component indicators in wavelength greater and more complex. Key words : Mixture-mixture design, OLS, GLS, split plot
