Judul: Analysis of Food Supplying Pattern and Strategy of Social Forestry's Fanner Household in Lampung Barat
Abstrak: The government of Lampung Barat District need information about food supplying pattern and strategy of Social Forestry's farmer household. This inf~tion is essential for formulating forestry policy and program that support foo~ecurity of Social Forestry's fanner who utilize the forestry by planting coffel: The objectives of this research were to: 1) know the socio economic cha~teristics of Social Forestry's fanner household in Lampung Barat District, 2) a~lyze food supply level of Social Forestry's fanner household in Lampung BarafllDistrict, 3) know the source and cost of food supplying of Social Forestry's fann~ household in Lampung Barat District, 4) know food supplying strategy of Sociaf Forestry's farmer household in Lampung Barat District. The research was cond@ted in October-November 2008 by using cross sectional study design. The sam~ was 90 Social Forestry's fanner households. The data obtained by the reseaWh were household characteristics; food supplying pattern and strategy whidi analyzed descriptively and inferentially. More than half of the samples (78~1;are small households with all fanners and housewives are in productive age and illl elementary school. The income per capita per month of the sample is Rp 509.626, obtained from both Social Forestry and Non Social Forestry works. The food &xpenditure per capita per month is Rp 213.136, while non food expenditure per c~ita per month is Rp 197.851. The larger shares of food expenditure are utiliz&i in food supplying of cereals (31,7%), vegetables and fruits (20,3%), and animi food (18,5%). Energy supplying of the sample for cereals, vegetables and fruits?'oils and fats, sugar, and others are sufficient, while energy supplying for tubers, animal protein, legumes, and oily seed are not sufficient. The food supply is obtained by purchasing (70,8%), self production (28,2%), and other sources (0,4%). Strategies for raising income conducted by the sample are searching supplementary income other than the main working field; conducting husbandry; and planting crops in garden. Saving is a strategy rarely conducted by the sample.

Judul: Nutritional Garrying Gapacity of Social Forestry In Lampung Barat District
Abstrak: The Government of Lampung Barat District issued Social Forestry Program to address forest degradation problem that caused by illegal logging. Therefore, nutritional carrying capacity of Social Forestry was important to be analyzed to understand the advantage of Social Forestry for farmer. The objectives of this research were to 1) analyze the characteristics of farmer household, 2) analyze the commodity diversity of Social Forestry, 3) analyze nutritional carrying capacity of Social Forestry, 4) analyze household food access based on income and food expenditure, and 5) analyze factors related to nutritional carrying capacity and food access of farmer household. The research was conducted by using cross sectional study design. The sample was 90 Social Forestry's farmer households chosen by using purposive sampling method. The result of the research shows that almost all samples are small family which has elementary school-education-Ievel and are Sundanese and Javanese. The average size of land organizing of Social Forestry each household is 1.3 ha with range 0.25-4 ha. The commodity diversity organized by the farmer household (52.2%) is included in low category with:;; 12 commodities. The average nutritional carrying capacity of Social Forestry is 2.754 Gal/cap/day, while the highest is in others (coffee and spices) which is 1.875 Gal/cap/day (68.1%) and the lowest is in legumes which is 2 Gal/cap/day (0.1%). More than half (67.8%) of the sample has reach nutritional carrying capacity"' 90% of ideal nutritional requirement. Social Forestry is the main source of income for fanner household with share of income is 63.9% of total household income. More than half (71,1%) of the sample has sufficient food access level (share of food expenditure is < 55% of income). The factors related to nutritional carrying capacity are: number of household member, housewife education, land size, income per capita, and commodity diversity, while the factors related to food access level are number of household member, land size, income per capita, and food caring capacity

Judul: Quantum Convolutional Neural Network (QCNN) for Classification Brain Tumor MRI Image
Abstrak: Penelitian ini bertujuan untuk mengembangkan model deteksi tumor otak menggunakan citra MRI dengan metode Quantum Convolutional Neural Network. Data yang digunakan adalah citra MRI otak yang terdiri dari citra tumor otak glioma, meningioma, hipofisis, dan negatif tumor yang dibagi kedalam data latih dan uji dengan rasio 80:20. Selanjutnya data latih dilakukan penyeimbangan dengan teknik oversampling. Dilakukan pengembangan model untuk mendeteksi tumor otak (biner), dan juga model untuk mengklasifikasikan jenis tumor otak (multiclass). Parameter yang digunakan dalam pengembangan model adalah jumlah ukuran filer = 2 dan kedalaman = 4, dengan qubit 4, dan dilatih dengan jumlah epoch sebanyak 10. Data akan diproses dengan metode Quantum Convolutional Neural Network yang terdiri dari lapisan quantum convolution, lapisan flatten, dan lapisan dense. Model multiclass mendapatkan akurasi 52%, setelah data latih diseimbangkan akurasi model meningkat menjadi 62%, sedangkan model biner mendapatkan akurasi 88%, setelah data latih diseimbangkan akurasi model meningkat menjadi 89%.
