The aim of this study was to investigate the modification of black glutinous rice starch (BGRS) as tablet filler. The black glutinous rice was treated with NaCl and NaOH to obtain BGRS. The native BGRS was modified by pregelatinizaion and prepared as co-composite and used as filler in tablet formulation compared with Starch 1500®. Propranolol was used as a model drug. The properties of tablets including disintegration time were evaluated. Interestingly, the disintegration times of the native BGRS was less than 90s which was faster than Starch 1500®. The results suggest that the native BGRS would be used in fast disintegrating tablets. While the disintegration times of pregelatinized BGRS was more than 30 min. Thus, the pregelatinized BGRS might be used for sustained release tablet. For the co-composite method, PVP K90 in the concentration of 1, 3, 5, 7 and 9 % w/w was incorporated with BGRS. The tablets of the co-composite producing by direct compression method were compared with tablets producing by wet granulation method using PVP K90 as binder. In concentration of 3% w/w PVP K90, the co-composite was comparable to wet granulation method in term of hardness and disintegration time. Thus, it could be used as direct compression filler in pharmaceutical field.

Keragaan morfologi dan kandungan antosianin padi beras merah (Oryza sativa L.) pada Kecamatan Munte dan Kecamatan Payung di Kabupaten Karo. Penelitian ini bertujuan untuk mendapatkan informasi morfologi dan kandungan antosianin padi beras merah (Oryza sativa L.). Penelitian ini dimulai dari Juni 2017dan selesai pada Januari 2018 di kecamatan Munte dan Kecamatan Payung Kabupaten Karo.Metode survei deskriptif menggunakan panduan International Rice Research Institute (IRRI). Teknik penentuan lokasi secara sengaja dan pengamblan sampel secara kebetulan.Uji kandungan antosianin menggunakan metode analitik dengan menghomogenkan sampel. Hasil eksplorasi didapatkan 72 genotipe yang dibagi menjadi tiga lokasi lahan. Berdasaran uji kandungan antosianin didapatkan lahan A memiliki kandungan tertinggi yaitu 0,5 mg/100 g dan terendah yaitu lahan B 0,08 mg/100 g.

Experiments were carried out to assess some insecticide modules against major insect pests of rice. Each module consists of a basal application of carbofuran 3G @ 1 kg a.i ha-1 at 20 DAT and Rynaxypyr 20 SC @ 30 g a.i ha-1 at 45 DAT except untreated control. All modules differ with each other only in third treatment which was applied in 65 DAT. The third treatment includes: Imidacloprid 17.8 SL @ 27 g a.i ha-1, Pymetrozine 50 WG @ 150 g a.i ha-1, Triflumezopyrim 106 SC @ 27 g a.i ha-1, Buprofezin 25 SC @ 250 g a.i ha-1; Glamore (Imidacloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1, Thiacloprid 24 SC @ 60 g a.i ha-1, Azadirachtin 0.03 EC @ 8 g a.i ha-1, Dinotefuran 20 SG@ 40 g a.i ha-1 and untreated control. All the treated plots recorded significantly lower percent of dead heart, white ear- head caused by stem borer and silver shoot caused by gall midge. Module with Pymetrozine 50 WG @ 150 g a.i ha-1 treated plot recorded significantly higher per cent reduction of plant hoppers (>80% over untreated control) and produced higher grain yield (50.75 qha-1) than the other modules. Among the different treated modules the maximum number of spiders was found in Azadirachtin 0.03 EC @ 8 g a.i ha-1 treated module plot followed by other treatments.
