Abstract

The study aims to enhance the quality and quantity of rice flour in drying process, especially when it is compared to the conventional sun drying. The rice flour was dried for 2 hours at different thickness of 1 and 1.5 cm. The temperatures were measured at several points of the dryer’s tray that is consisted of 4 layers, which was counted from the lowest layer as the first level. The samples were weighed in a small box which was put in the near border of the tray (box A) and in the centre of the tray (box B) for each layer. All measurements were done at interval of 15 minutes. Results showed that the temperature for drying the rice flour at depth 1.5 cm was 66 °C, which was higher than that of drying the rice flour at depth 1 cm (60.5 °C). In consequence, the relative humidity in the drying room at depth 1.5 cm was 35 %, which was lower than that of at depth 1 cm (61.8 %). However, the drying rate at depth 1.5 cm was lower than the drying rate at depth 1 cm. In addition, the distance of tray to the heater was also found to cause the low drying rate.

Abstract

Selama ini kualitas pisang sale di Aceh masih belum memuaskan konsumen. Perlu adanya upaya memperbaiki mutu pisang sale misalnya melalui peningkatan kualitas pengasapannya. Penelitian ini bertujuan untuk menguji performansi alat pengasap tipe rak pada pengolahan pisang sale dengan menggunakan  bahan bakar  biomassa. Sebuah alat pengasap pisang sale dirancang dengan 2 bahagian yang masing-masing mempunyai 7 buah rak. Alat pengasap ini diuji dengan variasi 3 jenis bahan bakar yaitu kayu bakar, kayu bakau dan tempurung kelapa. Proses pengasapan dilakukan sampai kadar air maksimal 18%. Parameter analisis meliputi temperatur dan kelembaban relatif ruang pengasapan, kapasitas kerja alat, rendemen, kadar air, karbohidrat, vitamin C dan uji organoleptik terhadap karakteristik bentuk, warna, bau, rasa dan tekstur. Hasil penelitian menunjukkan bahwa temperatur dan kelembaban relatif ruang pengasap ketika alat menggunakan bahan bakar tempurung lebih baik dari bahan bakar kayu. Hal ini mengakibatkan waktu yang diperlukan untuk pengasapan pisang sale dan kapasitas kerja alat ketika alat pengasap menggunakan bahan bakar tempurung kelapa juga lebih singkat yaitu 10 jam dan 4 kg/jam. Perbedaan jenis bahan bakar tidak menyebabkan terjadinya perbedaan rendemen pisang sale. Kandungan karbohidrat pisang sale mengalami peningkatan setelah proses pengasapan menjadi 8,84%, 10,18%, dan  9,45%  masing-masing menggunakan bahan bakar kayu bakar, kayu bakau dan tempurung kelapa. Sedangkan kandungan vitamin C pisang sale mengalami penurunan menjadi 7,37 mg/100g (kayu bakar), 7,458 mg/100g (kayu bakau), dan 7,194 mg/100g (tempurung kelapa). Berdasarkan uji organoleptik, pisang sale yang proses pengasapannya menggunakan bahan bakar tempurung kelapa dan kayu bakau adalah yang paling disukai bentuk, warna, bau, rasa dan teksturnya.

Abstract

Abstrak. Lengkuas (Alpinia galanga) adalah salah satu tanaman penting bagi masyarakat Indonesia. Tanaman ini dapat digunakan untuk bumbu masakan dan obat herbal. Tujuan kajian ini adalah untuk menduga umur simpan lengkuas segar dengan menggunakan model Arrhenius. Lengkuas segar yang baru dipanen dibersihkan dan dipotong-potong dengan ukuran 2cm, kemudian disimpan pada suhu 5, 10 dan 28°C. Evaluasi dilakukan oleh 25 orang panelis dengan menggunakan skala hedonic dari sangat suka sampai sangat tidak suka terhadap warna, kesegaran, aroma dan tekstur. Parameter yang diamati adalah kadar air dan kadar sari larut dalam air. Parameter tersebut diamati dalam interval 3 hari selama 21 hari atau sampai sampel dinyatakan tidak disukai oleh panelis pada salah satu kriteria hedoniknya. Hasil penelitian menunjukkan bahwa pad asuhu 28°C, lengkuas dapat disimpan selama 3 hari, sedangkan pada suhu 10 dan 5°C, lengkuas dapat disimpan selama 12 dan 21 hari. Energi aktivasi (EA) dan tingkat perubahan mutu (Q10) karena kadar sari larut dalam air lebih besar dari energi aktivasi (EA) dan tingkat perubahan mutu (Q10) karena kadar air lengkuas. Namun demikian, kedua parameter tersebut tidak tepat digunakan untuk menduga umur simpan lengkuas. Shelf-Life Prediction of Galanga by Using Arrhenius Model Based on Its Moisture and Water Soluble Extract Content Abstract. Galanga (Alpinia galanga) is one of important plants for Indonesian people. It can be used as spices and also as herbal medicine. The aim of this study is to predict the shelf-life of fresh galanga by using Arrhenius model. Fresh harvested galanga, which was cleaned and chopped at width about 2 cm, was stored at temperatures 5, 10, and 28°C. The evaluation was done by 25 respondents by using hedonic scale from the range of like very much until dislike very much. This hedonic evaluation was assessed, based on colour, freshness, aroma, and texture. Parameters observed were moisture and water soluble extract content. These parameters observed at interval 3 days for 21 days or until the samples were rejected by respondents for at least one of hedonic factors. Results showed that at temperature 28°C, galangal can be stored for 3 days. However, at temperature 10 and 5 °C, galangal can be stored for 12 and 21 days, respectively. The energy act ivation (EA) and the rate of quality change (Q10) due to water soluble extract were higher than those of water content. Nevertheless, these two parameters cannot be used in prediction the shelf-life of fresh galanga.

Abstract

Abstract: The development of science and technology has brought about many changes in society life. However, the main concern here is that the changes have caused the existence of moral crisis. This is based on the fact that the development of knowledge in the area of technology and information is not balanced with the development of moral of modern society. The reality of life that drives educa­tional activity continuously to run and change that demand the new acceleration in educational world, especially moral education. Therefore, the concept of moral education still needs to be specifically examined because the concept of moral education is very important in educational world. Moral education is not a new problem. There are many experts that have formulated the concept of education and have taken moral as not a separated part of educational system. Even, moral education has to integrate the spiritual and intelectual aspects and also normatif  and hystorical aspects (reality). The integration of all these aspects will become the core for the balance between the aspects of cognitive (mind), affective (faith), and pychomotoric (deed) in education practices.Abstrak: Perkembangan sains dan teknologi telah banyak memberi perubahan dalam kehidupan masyarakat. Tetapi, yang memprihatinkan adalah perubahan itu justru mendorong munculnya krisis moral. Hal ini didasarkan pada kenyataan bahwa kemajuan ilmu pengetahuan di bidang teknologi dan informasi tidak selalu sebanding dengan kemajuan di bidang moral pada masyarakat modern. Realitas kehidupan yang menggiring aktivitas pendidikan terus berjalan dan berubah-ubah menuntut adanya suatu akselerasi baru dalam dunia pendidikan terkhusus pendidikan moral. Oleh karena itu, konsep pendidikan moral masih perlu dikaji secara spesifik karena konsep pendidikan moral adalah hal yang sangat penting dalam dunia pendidikan. Pendidikan moral memang bukanlah persoalan baru. Banyak ahli pendidikan telah merumuskan konsep pendidikan dan menjadikan moral sebagai bagian yang tidak terpisahkan dari sistem pendi­dikan. Bahkan pendidikan moral harus mampu mengintegrasikan aspek-aspek spiritual dan intelektual serta aspek normativitas dan historitas (realitas). Integrasi keseluru-han aspek tersebut akan menjadi inti bagi keseimbangan aspek kognitif, (akal), afektif (iman), dan psikomotorik (amal) dalam pendidikan secara praktis.
