Indonesian nutmeg export is constrained due to aflatoxin content that exceeds the minimum limit. This study was aimed at examining the effectiveness of three drying types of nutmeg to diminish aflatoxin contamination. The three drying types tested were (a) the rack type house with a source of solar energy heat combined with a kerosene stove fire, (b) the drying bases one meter above the ground with or without a black cloth cover, and (c) the floor drying 5 cm above the ground with or without black cloth cover. Unpeeled nutmegs were dried in the drying racks until they dried (sound when shaken by hand). After that they were. peeled and redried in the same type of dryer. Observation parameters included temperature, humidity, drying time, moisture content, oil content, oleoresin, myristicin, and aflatoxin content. The results showed that the drying time in the house-type drying rack was 51.5 hours, longer than the para-para and drying floor (30 hours). The temperature during drying in the drying house was 35.6-37.31 0 C lower than the other two types of dryers. However, its humidity was the highest (40.71-49.33%). The moisture content of shelled nutmegs and peeled nutmegs from all drying types fulfill the requirements (< 10%). The total aflatoxin contamination in shelled nutmegs and peeled nutmegs was < 3.28 µg/kg, while B1 aflatoxin was < 1.06 µg/kg, so that they fulfilled SNI standard. All three drying types can be recommended to be tested further in field scale. Keywords : Nutmeg, Myristica fragrans, drying technology, seed quality.

Modifikasi hidrogel dengan polimer alami mulai banyak dikembangkan. Hal ini dimaksudkan untuk mendapatkan hidrogel dengan kualitas mutu yang lebih baik dan ramah lingkungan. Oleh karena itu, penelitian ini bertujuan untuk mengetahui pengaruh penambahan pati tapioka yang telah dimodifikasi dengan ekstrak jahe pada hidrogel PVAM hasil sintesis PVA dengan maleat anhidrida (MA) menggunakan inisiator aluminium persulfat (K 2 S 2 O 8 ). Sintesis hidrogel dilakukan dengan reaksi kopolimerisasi cangkok. Parameter yang diamati meliputi analisis gugus fungsi dengan spektroskopi FTIR ( Fourier transform infrared ), fraksi gel, derajat pengembangan, dan derajat grafting . Hasil penelitian menunjukkan bahwa puncak serapan dari hidrogel PVAM- g -tapioka jahe lebih lemah dibandingkan PVAM yang ditandai dengan ikatan C=C pada bilangan gelombang 1625 cm - 1. Nilai fraksi gel dan derajat grafting hidrogel PVAM- g -tapioka jahe (85,42% dan 97,62%) lebih tinggi dibandingkan PVAM- g -tapioka (76,56% dan 92,19%). Akan tetapi, derajat pengembangan hidrogel PVAM- g -tapioka jahe lebih rendah (275,72%) dibandingkan PVAM- g -tapioka (286,58%). Penelitian ini memberikan informasi bahwa penambahan ekstrak jahe dapat meningkatkan sifat fisik dari hidrogel PVAM- g -tapioka.
