Learning media is one of the important aspects of supporting learning processes. This research development aims at producing audiovisual learning media of hydroponic system on biotechnology topic which are valid and effective. The development model used is a modified 4D development model. The data collected came from the subject experts, media specialists, and teachers as practitioners in the field using the media. The data collection instruments were in the form of questionnaires and interviews. The data were analyzed by the using descriptive qualitative and the descriptive statistics. The study was tested to the biology teachers from twelve senior high schools by using a questionnaire based on the seven criteria (in conformity with the learning objectives, the learners, the characteristics of the appeal, the time of purchase, the media cost, ease of use, and the context of use). The audiovisual learning media of hydroponic system developed was categorized as the very effective learning medium (88.17%) in the high schools and fulfilled all of the criteria.
Abstract. Hasanah R, Daningsih E, Titin. 2017. The analysis of nutrient and fiber content of banana (Musa paradisiaca) sold in Pontianak,. This study aimed to find out the effect of varieties of banana and market places to nutrients and fiber of bananas which were sold in Pontianak. Completely Randomized Design (CRD) Factorial model with main factors of varieties of banana (barangan, masak hijau, singapura), market places namely traditional market, fruit stores, and side road kiosk, and the combination of varieties and market places of banana. The variable tests were carbohydrate, glucose, fructose, sucrose, protein, lipid, vitamin C, crude fiber, water and ash content test. The result was processed with SAS application 6.12 version using ANOVA CRD Factorial and significances followed by LSD α=0.05. Result found varieties of banana affected on significantly to total carbohydrate, glucose, fructose, sucrose, vitamin C, lipid, and water but did not significantly affect on crude fiber, and ash. The market places gave no significant effect on total carbohydrate, glucose, fructose, sucrose, protein, vitamin C, crude fiber, water but gave significant affect on ash content. The combination between varieties and market places affected significantly on specific nutrient content. Barangan was good on total carbohydrate, vitamin C, and ash whilst masak hijau was highest on glucose, fructose, sucrose, and crude fiber. In addition, singapura was highest on protein, lipid and water.
AbstrakNanas dapat digunakan sebagai tambahan cita rasa pada biscotti yang merupakan makanan khas Itali. Modifikasi biscotti dapat diujikan secara organoleptik untuk mengetahui perbedaan konsentrasi nanas (Ananas comosus (L.) Merr.) yang disukai oleh konsumen. Parameter yang diamati adalah warna, aroma, rasa nanas, rasa manis, tekstur dan kesukaan. Desain penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan konsentrasi nanas (150, 175, 200 gr) dengan 25 ulangan. Uji organoleptik dengan 25 panelis tidak terlatih yaitu siswa SMA Negeri 8 Pontianak menggunakan lembar uji skalar. Data dianalisis menggunakan SAS. Konsentrasi nanas 200 gr berpengaruh signifikan terhadap aroma, tetapi tidak berpengaruh pada parameter lainnya seperti warna, rasa nanas, rasa manis, tekstur dan kesukaan. Perlakuan 200 gr nanas memberikan kriteria cukup disukai oleh panelis berdasarkan rata-rata skor. Dengan demikian nanas dapat digunakan untuk biscotti dengan cita rasa lokal.Kata kunci: nanas, biscotti nanas, uji organoleptik Abstract Pineapple can be used as an added flavor to the biscotti which is a typical Italian food.Modification of biscotti can be tested organoleptically to determine the difference in the concentration of pineapple (ananas phyaces (L.) Merr.) that consumers liked. The observed parameters are color, aroma, pineapple flavor, sweetness, texture and liking. The research design uses complete random design (RAL) with 3 pineapple concentration treatments (150, 175, 200 gr) with 25 repeats. Organoleptic Test with 25 untrained panelist, SMA Negeri 8 Pontianak students use scalar test sheet. Data is analyzed using SAS. The concentration of Pineapple 200 gr significantly affects the scent but has no effect on other parameters such as color, pineapple flavor, sweetness, texture and taste. The treatment 200 gr pineapple gives the criteria quite liked by the panelist based on the average score. Thus, the pineapple can be used for biscotti with a local flavour. PENDAHULUANNanas (Ananas comosus (L.) Merr.) merupakan tanaman buah-buahan yang dapat diproduksi sepanjang tahun, tidak tergantung musim dan termasuk dalam salah satu produk buah unggulan nasional karena hasil produksinya yang melimpah, termasuk di Kalimantan Barat. Berdasarkan data Badan Pusat Statistik (BPS) Kalimantan Barat tahun 2017, nanas menempati urutan ke tiga dengan hasil produksi sebesar 34.950 ton atau 11,96% dari produksi buah yang dihasilkan di Kalimantan
<p>Tujuan penelitian ini adalah mengukur pertumbuhan tanaman selada. Penelitian ini menggunakan Rancangan Acak Lengakap (RAL) Faktorial dengan faktor utama (hiroponik rakit apung dan rasio nutrisi), dan faktor kombinasi antara keduanya. Pengukuran dilakukan selama 14 hari (7 kali pengamatan) dengan enam parameter (panjang akar, tinggi tanaman, jumlah daun, kadar klorofil, berat basah dan berat kering). Data dianalisis menggunakan SAS. Jika terdapat perlakuan yang signifikan dilanjutkan dengan uji LSD pada alfa 0,05. Hasil menunjukan rakit apung dinamis meningkatkan pertumbuhan selada secara signifikan dibandingkan rakit apung statis. Rasio nutrisi N3 meningkatkan pertumbuhan selada secara signifikan dibandingkan rasio nutrisi lainnya pada semua parameter kecuali jumlah daun. Kombinasi antara rakit apung dinamis dan rasio nutrisi N3 merupakan pertumbuhan tanaman selada tertinggi secara signifikan dibandingkan dengan 7 kombinasi lain.</p>
