The purpose of this study was to evaluate several superior clones of Robusta coffee through semi-wet processingg. The research was conducted at the Lampung AIAT Experimental Garden in Natar, Way Haron Village, the Lampung AIAT Laboratory and the Polinela Food Laboratory from April 2019 to October 2019. The clones used in the study were BP 534, BP 939, BP 436 and SA 203. Harvesting was carried out by red picking and then the berries were sorted. Analysis of the quality of coffee beans refers to Indonesian National Standard (SNI) 01-2907-2008 and SNI 01-3542-2004 for ground coffee. The results showed that clones BP 534 and BP 939 were classified as quality I, BP 436 and SA 203 clones were classified as quality II. The BP 534 have the highest protein, ash and carbohydrate content with the lowest fat content, while the fiber value is 17,389%. The color values (L) of coffee beans were ranged from 42.907 to 47.250. There was an increase in the L value from roasted coffee to ground coffee for all clones. The quality of ground coffee from four Robusta coffee clones meets the quality standards based on SNI 01-3542-2004. Ground coffee from clone BP 534 was the best compared to other clones.

Ambon bananas are one of several types of bananas exported from Lampung to other countries. Due to the distance and the length of time, the bananas undergo ripening before arriving at the destination country. The current research aims to increase the shelf life of bananas so that they are still fresh and fit for consumption by consumers. The experimental design used was a completely randomized design with ethylene absorbent formulation treatment, namely B0 = Control (0 g/kg ethylene absorbent material (KMnO4 + clay), B1 = 1 g/kg ethylene absorbent material (KMnO4 + clay), B2 = 2 g/kg ethylene absorbent material (KMnO4 + clay), and B3 = 3 g/kg ethylene absorbent material (KMnO4 + clay). Storage was performed at a temperature of 16−18°C for 24 days after treatment (DAT). During storage, samples were taken and observed for storage days 0, 4, 7, 10, 14, 17, 21, and 24. The data were statistically analyzed and continued with Duncan’s test at the 5% level. The control treatment (B0) of Ambon bananas can only be stored up to 10 DAT, while the B1 treatment is 14 DAT. For B2 treatment, Ambon bananas can be stored up to 21 DAT, and the best treatment is B3 (3 g/kg KMNO4 + clay), which can withstand banana ripeness until the end of the observation (24 DAT).
