Abstract

his research was done in order to utilize agricultural waste (rice straw) as substrate to produce crude cellulase enzyme from Aspergillus niger. This research was conducted in two stages; the first stage was determination of the initial pH and fermentation time by pH treatment (5, 6 and 7) and fermentation time (7, 9 and 11 days). The second stage was determination of concentration of NaOH treatment and concentration of substrate, namely: concentrations of NaOH (2, 4 and 6%) and concentrations of substrate (1, 2 and 3% (w/v)). The results showed that the fermentation time of 9 days with the initial pH 6.0 was the optimal condition for production of crude cellulase enzyme from A. niger with rice straw as a substrate. The highest enzyme activity derived from interaction of delignification treatment with NaOH concentration of 6% and 2% rice straw substrate which produces endoglukanase enzyme activity (0.037 units/ml), filter paperase activity (0.033 units/ml), soluble protein (0.362 mg/ml), and specific activity of filter paperase (0.123 units/mg).

Abstract

Tujuan dari penelitian ini adalah sebagai percontohan pola pergeseran aktivitas Masyarakat Bali melalui sebuah komoditas, yang dalam hal ini adalah komoditas berbasis budaya dan melihat pola perkembangan dan pengembangan Endek sebagai sebuah komoditas berbasis budaya di Kabupaten Klungkung. Studi ini menggunakan pendekatan gabungan dari metode penelitian historis, etnologi, deskriptif kualitatif dan kultural. Pengumpulan data dilakukan dengan teknik observasi dan wawancara langsung kepada para stakeholder yang ditentukan menggunakan metode purposive dan snowball sampling. Kerajinan tenun endek di Klungkung dapat menggambarkan adanya pergeseran aktivitas pada masyarakat di Klungkung. Aktivitas menenun yang semula merupakan aktivitas sekunder kemudian berkembang ataupun bergeser menjadi salah satu aktivitas primer (mata pencaharian). Bergesernya fungsi aktivitas adalah sebagai akibat dari bergesernya fungsi dari kain endek yang sebelumnya adalah artefak bergeser menjadi komoditas. Pola perkembangan dan pengembangan yang terjadi pada kain endek di gerakkan oleh proses adopsi teknologi, yakni teknologi yang terkandung pada fasilitas rekayasa (ATBM), teknologi yang terkandung dalam informasi yakni media (cetak, televisi, internet), teknologi yang terkandung pada manusia (Observasi, Experience) dan teknologi yang terkandung dalam organisasi (proses akulturasi). Proses adopsi teknologi mengakibatkan terjadinya perkembangan melalui sebuah pengembangan yang kemudian menghasilkan bentuk baru dikenal dengan istilah komodifikasi.

Abstract

Penelitian ini bertujuan untuk menentukan konsentrasi starter dan penambahan gula yang optimal untuk memperoleh karakteristik wine salak yang terbaik. Penelitian ini menggunakan Rancangan Acak Kelompok pola factorial dengan dua faktor. Faktor pertama adalah konsentrasi starter yaitu: 5, 10 dan 15% (v/v) dan faktor kedua adalah penambahan gula yaitu: 10, 15, 20 dan 25% (b/v). Hasil penelitian menunjukkan bahwa konsentrasi starter dan penambahan gula berpengaruh terhadap karakteristik wine salak. Pada konsentrasi gula yang lebih tinggi dapat menhasilkan kadar alkohol yang lebih tinggi juga, karena terdapat lebih banyak substrat yang dimanfaatkan oleh khamir untuk memproduksi alkohol. Wine salak dengan karakteristik terbaik diperoleh dari perlakuan konsentrasi starter 15% (v/v) dan penambahan gula 25% (b/v), dengan kadar alkohol tertinggi yaitu sebesar 12,25% dan juga memiliki nilai uji efektifitas terbaik yaitu sebesar 1,33.
