Abstrak: Analisis Elastisitas Tiga Bahan Pangan Sumber Protein Hewani di Indonesia.Penelitian ini bertujuan untuk menganalisis perilaku permintaan rumah tangga atas tiga sumber protein hewani (ikan, daging sapi, dan daging ayam) dikaitkan dengan karakteristik rumah tangga yang berbeda dan menganalisis respon rumah tangga di Indonesia terhadap perubahan harga dan pendapatan pada konsumsi ketiga komoditas tersebut. Model yang digunakan untuk melakukan estimasi adalah model Almost Ideal Demand System (AIDS), dengan menggunakan data dari Indonesia Family Life Survey gelombang 4 (IFLS 4). Jumlah rumah tangga sumber data yang dianalisis dalam penelitian ini berjumlah 839 rumah tangga. Hasil penelitian menunjukkan secara parsial harga ikan, harga daging sapi, pengeluaran rumah tangga, wilayah geografi, dan jumlah anggota keluarga berpengaruh terhadap pangsa pengeluaran untuk produk ikan-ikanan, daging ayam, dan daging sapi. Elastisitas permintaan harga permintaan untuk ikan, daging sapi, dan daging ayam masuk dalam kategori inelastis, elastisitas pendapatan untuk daging sapi dan daging ayam masuk kategori elastis, dan ikan mempunyai elastisitas pendapatan yang inelastic. Kata kunci: model Almost Ideal Demand System (AIDS), elastisitas harga permintaan, elastisitas silang, elastisitas pendapatan. Abstract: Elasticity Analysis for Three Animal Protein Resources in Indonesia.This study aimed to analyze the behavior of household demand on three sources of animal protein (fish, beef, and chicken) were associated with different household characteristics and analyze the response of households in Indonesia to changes in price and income on the consumption of fish, beef, and chicken. Almost Ideal Demand System (AIDS) was adopted in this study, using data from the Indonesia Family Life Survey wave 4 (IFLS 4). Total number of the household analyzed in this study amounted to 839 households. The results showed that partially price of fish, beef prices, household expenditure, geographic region, and number of family members affect the share of expenditure fisheries products, chicken, and beef. The results implied that Price elasticity of demand for demand for fish, beef, and chicken were categorized as inelastic. While the income elasticity for beef and chicken were elastic, furthermore income elasticity for fish was inelastic.Keywords: Almost Ideal Demand System (AIDS) model, demand price elasticity, cross elasticity of demand, income elasticity of demand. PENDAHULUANTingkat konsumsi rumah tangga merupakan salah satu komponen dalam pembentukan Produk Domestik Bruto (PDB) Indonesia. Perkembangan dari tahun ke tahun menunjukkan bahwa konsumsi rumah tangga selalu menjadi kontributor terbesar dalam pembentukan nilai PDB. Dalam 10 tahun terakhir (2001-2010) rata-rata pertumbuhan PDB mencapai 5,22% dan

Even though economics learning in Senior High Schools has been able to increase students’ economic knowledge, their economic behavior is still far from being appropriate, whereas their concern for others, the environment, and even for themselves is lacking. The aims of this study were to apply caring economics learning (CEL) at senior high schools in Indonesia and to observe the internalization of caring economics attitude among the students through action research. It contained instructional package consisting of lesson plans, student worksheets, instructional materials, instructional media, and learning assessment in the form of situational judgment tests (SJTs). The CEL employed case method that was implemented in three learning activities. The data were obtained through observation, interviews, tests, and documentation. The study has revealed that the CEL was assessed by the observers as good and excellent. The success of caring attitude development on the students was reflected in the number of students showing caring attitudes, which increased from the first learning activity (52%) to the last one (95%). Based on the SJT-1, 55.56% of students achieved high scores and 44.44% had moderate scores. Based on the SJT-2, the number of students with high scores increased significantly (77.78%), while the number of students who had moderate scores decreased considerably (22.22%).
