<p>Salah satu diversifikasi pengolahan pisang adalah menjadi tepung pisang instan dengan pengering drum dryer. Teknologi pengeringan ini memerlukan bahan pengisi dan agen anti pencoklatan. Tujuan dari penelitian ini adalah mengoptimasi konsentrasi tapioka, asam sitrat dan puree pisang dalam proses pembuatan tepung pisang Cavendish instan. Penelitian ini menggunakan rancangan Response Surface Methodology (RSM), tiga parameter yang dioptimasi adalah konsentrasi tapioka, asam sitrat dan puree pisang. Level dari input parameter adalah tapioka 3-10%, asam sitrat 150-300 ppm dan puree pisang 1-50%. Karakteristik fisiko-kimia produk tepung pisang instan kemudian dianalisis, meliputi kadar air, abu, lemak, protein, karbohidrat, serat kasar, kalori, dan warna (oHue). Hasil prediksi variabel respon dari formula optimal yaitu kadar air 2,67 %, abu 1,60 %, lemak 3,09%, protein 2,38%, karbohidrat 90,26%, serat kasar 7,49%, kalori 398,84 Kkal/100g, dan warna 67,78oHue (kuning kecoklatan). Formula optimum tepung pisang instan adalah formula 6, yaitu dengan penambahan tapioka 6,50%, asam sitrat 225 ppm dan puree pisang 30%. Tepung pisang instan berpotensi untuk digunakan sebagai makanan sarapan melalui formulasi dengan penambahan bahan yang lain seperti lemak dan protein.</p><p> </p><p><strong>Optimisation of The Instant Cavendish Banana Flour Formula by Response Surface Method. 2018.

The purpose of this research was to get the optimum concentration of tapioca, citric acid and banana puree to produce instant banana flour.The experiment used Response Surface Methodology (RSM), with three parameters being optimized, i.e. the concentration of tapioca, citric acid and banana puree. The percentage used for tapioca in the range of 3-10 %, citric acid 150-300 ppm and banana puree 1-50%. TThe instant banana flour was analyzed for its physicochemical characteristics, i.e: moisture, ash, fat, protein, carbohydrate, crude fiber content, energy, and color 67.78 (oHue). The result of variable response prediction from the optimum formula was moisture content 2.67%, ash 1.60%, fat 3.09%, protein 2.38%, carbohydrate 90.26%, crude fiber 7.49%, color 67.78oHue brownish yellow, energy 398.84 kcal/100g. The optimum formula was formula 6, with the addition of tapioca 6.50%, citric acid 225 ppm and banana puree 30%. This product has a potential to be used as a breakfast food through further formulations with the addition of other ingredients such as fat and protein.</p>
ABSTRAK. Alpinia merupakan jenis bunga potong tropis yang disukai kosumen hotel, floris, dan rumah tangga, namun belum banyak dikenal masyarakat luas. Oleh karena itu jenis bunga potong tersebut perlu disosialisasikan memiliki potensi untuk dikembangkan dalam agribisnis tanaman hias. Penelitian bertujuan mendapatkan informasi preferensi konsumen terhadap bunga potong Alpinia. Penelitian dilakukan pada bulan Agustus 2004 sampai Maret 2005 dengan metode survai. Responden yang dipilih ialah pedagang (floris), hotel (berbintang empat dan lima) dan rumah tangga masing-masing sebanyak 10, 9, dan 13 responden. Pemilihan responden dilakukan secara sengaja, berdasarkan pertimbangan bahwa responden tersebut merupakan konsumen Alpinia dalam bentuk bunga potong. Analisis data untuk menentukan preferensi konsumen dilakukan dengan menggunakan Chi-Square (P=0,01) dan untuk faktor-faktor yang memengaruhi konsumen dalam pemilihan Alpinia menggunakan metode ranking. Hasil penelitian menunjukkan bahwa faktor utama yang menjadi pertimbangan konsumen dalam pembelian bunga potong Alpinia ialah warna bunga. Selera konsumen hotel terhadap bunga potong Alpinia ialah warna merah, ukuran besar, tingkat kemekaran 50% kuncup, jumlah daun per tangkai tiga helai, panjang tangkai lebih dari 50 cm, dan harga sedang atau murah. Konsumen rumah tangga menyenangi bunga Alpinia berwarna merah, ukuran besar, mekar penuh, tanpa daun, panjang tangkai lebih dari 50 cm dengan harga sedang atau murah. Hasil penelitian diharapkan dapat menjadi masukan bagi pengembangan agribisnis Alpinia dan upaya pemuliaannya.Katakunci: Alpinia; Bunga potong; Preferensi konsumen. ABSTRACT. Sunarmani, Nurmalinda, and D. Amiarsi. 2011. Consumer's Preference on Alpine Cut Flower.Alpine is a tropical cut flowers which is preferred by consumers of hotels, florists, and households, but the cut flower has not been widely known by people. It is required to be introduced for the development of its agribusiness. The objective of this research was to identify the consumer's preference on Alpine cut flower. Primary data were collected from 10 respondents of florist, nine respondents of four and five star hotels, and 13 respondents of household. The respondents were purposively chosen based on that they are Alpine consumers. Consumer's preferences were analyzed by a ranking technique and tested by Chi-Square analyses (P=0.01). The results showed that the major factor of consumenr's preference was color interest. Hotel consumers prefered red color, outgrows flower, 50% buds opening, total leaf per stalk was three, stalk length more than 50 cm, and lower or medium price. Meanwhile, family consumer's favoured rudle flower, big, and full opening flower, without leaf, stalk length more than 50 cm, and low or medium price. This comsumer's preference study will be useful for farmers to develop Alpine cut flower needed by consumers, and also for researchers to develop new superior varieties.
