"ABSTRAKThe effect of alkali dehulling on pearled grain, milling quality, and flour colour of sorghum grain was under study. Aqueous solutions of sodium hydroxide (NaOH) as dehulling agents hulled grain. Four soaking periods (5;10;15; and 20 minutes) and NaOH concentrations (2,5;5;7,5;10;12,5; and 15 w/w) were investigated. A randomized complete block design with 3 replications was used. The treated grain was washed, neutralized with acetic acid, and washed again. After treated the grains were milled by Satake Polish Rice Machine and then analysed. Physical analysis included the hull removed, milling quality and flour colour. The experiment indicated that the optimum conditions of sodium hydroxide solutions to removed the hull grain was 8,3% at various concentrations to removed (15%, 10% and 5%), and various times (5min.; 10min.; and 15min.). Under these conditions, the yield recovery of milled whole grains were not significantly affected by alkali dehulling. Colour of starch from dehulled grain appeared to be whiter than starch from whole grain, which were indicated by flour reflectance."

"Tesis ini membahas pola interaksi dan komunikasi berbagi pengetahuan para peneliti dalam menciptakan inovasi di Lembaga Ilmu Pengetahuan Indonesia (LIPI) dan faktor-faktor yang mempengaruhi berbagi pengetahuan. Penelitian ini adalah penelitian kualitatif dengan pendekatan fenomenologi. Hasil penelitian menunjukkan bahwa kesadaran peneliti dan interpretasi makna berbagi pengetahuan yang dilandasi oleh nilai, keyakinan, motivasi dan norma mempengaruhi tindakan berbagi pengetahuan. Saran yang diajukan adalah: lembaga perlu membangun kedekatan dan kerja sama antar peneliti guna mengembangkan pengetahuan yang menunjang penciptaan inovasi; peran perpustakaan sebagai pusat informasi harus lebih diberdayakan dalam manajemen pengetahuan; penanaman nilai-nilai organisasi, seperti nilai kebersamaan, kepercayaan terhadap individu lainnya hendaknya diwujudkan dalam program nyata, bukan hanya berupa slogan sehingga dapat dirasakan dan diingat oleh seluruh individu dalam lembaga.

This thesis discusses the patterns of interaction and communication researchers to share knowledge in creating innovations at Indonesian Institute of Sciences (LIPI) and the factors that influence knowledge sharing. This research is a qualitative study with phenomenology approach. The result showed that researcher‟s awareness and meaning interpretations of knowledge sharing were based on values, beliefs, motivations and norms.

The suggestions are: institution needs to construct closeness and cooperation among researchers to develop knowledge that supports the creation of innovation: the role of libraries as information centers should be more empowered in knowledge management; Constructing the organizational values, such as sharing values, trusting to others should be realized in a real program, not only as a slogan/motto butit should be felt and implemented by all individuals in the institution."
