The ripeness of oil palm fruits is one of the key factors for crude palm oil qualities. Recently, electronic nose systems have been developed intensively for fruit quality assessment which relates odors to ripeness levels. This study developed an electronic nose system to characterize the ripeness levels of oil palm fruits using output voltage of each sensor and fruit hardness. The system consisted of a sensor chamber and a sample chamber. The sensor chamber consisted of eight MOS gas sensor modules of MQ series. Samples were oil palm fruits taken from oil palm fresh fruit bunches (FFB) which were previously categorized traditionally into unripe, ripe, over ripe, peeled and put into the sample chamber. Some of the fruits were also used for hardness measurement. To quantify the output voltages for each sensor, integrated trapezoid areas were calculated and related to the fruit hardness values. The results showed a significant voltage difference of each sensor for the three ripeness levels. Only four out of eight sensors showed significantly higher voltages. Three sensors which can significantly differentiate the ripeness levels are MQ3, MQ5, and MQ135 which MQ135 is the best. This shows that the electronic nose is potential for oil palm fruits. Keywords: electronic nose, fruit hardness, MOS gas sensor, oil palm fruit, ripeness

Maggot black soldier fly (Hermetia illucens) is a protein source of feed which is highly favored by poultry, especially ducks and chickens. However, it is feared that the provision of live maggot in ducks will affect the organoleptic quality of the egg, especially its taste and aroma. Therefore this study aims to determine the organoleptic quality of duck eggs fed Hermetia illucens maggot feeds in a living state. The study used 120 alabio ducks which were placed in a postal cage. The design used was a completely randomized design, each treatment using six replications. Each replication is taken egg sample to be tested panelists. The panelists used were 67 panelists who were somewhat trained. The data obtained were analyzed of variance and Duncan's multiple range test. The treatments that were tried consisted of P1: low protein rations without live maggot, P2: low protein rations with live maggot administration 40 g/bird/day, P3: high protein rations without live maggot administration, and P4: high protein rations with live maggot administration 40g/bird/day. The results showed that the treatment affected the texture, flavor, and aroma of boiled eggs. Ducks fed with high protein ration coupled with the provision of live maggot 40 g/bird/day produce softer textures, tastes quite good, and aroma more fishy. Keywords: Maggot, duck eggs, organoleptics
