Abstract

This study aimed to test the application of the Deep Flow Technique (DFT 4cm dan DFT 2cm)  and Nutrient Film Tecnique (NFT) bare root system hydroponic system on water spinach plants by calculating plan water requirements and measuring vegetative growth of water spinach plants with thickness / water level different. The results showed that the CU (Coefficient Uniformity) value was 95% in that DFT 4cm, 111,55ml of water as used, plant height and number of leaves were relatively that same as t6he other treatments with a plant mass weight of 181.28gr, with a stem meter of 12.92cm. DFT 2cm required 90.17ml of water with a plant mass weight of 160.33gr. NFT needs water as much as 106.57 ml with a plant mass weght of 153.28gr.

Abstract

ABSTRACTThe purpose of this study was to examine the effect of the thickness of irrigation water flow in the Deep Flow Technique (DFT) hydroponic system on the amount of plant water requirement (or evapotranspiration) and the Water Use Efficiency (WUE) in rice cv. Serayu at the vegetative phase. This research was carried out in a tropical greenhouse roofed with polyethylene (PE) plastic film. The treatments in this study were three kinds of thickness of  micro irrigation in the DFT hydroponic system, i.e. 2, 4 and 6 cm. The results showed that water requirement for each planting hole in rice plants during the vegetative phase (60 days) were 14.3650, 12.7025, and 11.3108 with biomass of 62.4576, 58.2874 and 52.6370 g, respectively for 6, 4 and 2 cm. The water use efficiency in 2, 4, 6-cm-DFT-system were 2.3268,  2.293 and 2.1740 g/L, respectively. Keywords: Hidroponics, Deep Flow Technique, Evapotranspiration, Water Use Efficiency

Abstract

ABSTRACT The objective of this research was to design a pulper machine model TEP-JLL 2015 for fresh coffee robusta used in rural areas of Tana Toraja district. The machine was designed based on the analysis of physical characteristics of Robusta Tana Toraja coffee and literature study. The analysis result of physical characteristics showed the average length, thickness width was 12.494 mm, 12.802 mm, 10.687 mm, respectively, and the bulk density was 1,115 kg/m3. The theoretical hopper capacity of this machine was 3.7687 kg. Assuming the cylinder speed was 111.594 rpm with an effective distance setting system or flawed setting of 1.2 cm, the theoretical capacity of this pulper machine was 380.62 kg/hour. Keywords: fresh Robusta coffee fruit, pulper machine

Abstract

Abstract This study aims to design a CSM 16 TP type corn seeds planter by adopting the TP CSM 15 type corn seeds planter and a corn seeds planter integrated with the Kubota M9560 four-wheeled tractor, and testing technically the corn seeds planter covering effective field capacity, theoretical field capacity, field efficiency and planting effectiveness. The results of the study were 1 unit of maize seed planting tool TP CSM 16 type consisting of 2 static planting units, and technical testing of corn seeds planter in 10 m  5 m plot of land with 3 repetitions obtained the results is the average effective field capacity of 0,080 ha/hour, the average theoretical field capacity of 0,110 ha/hour and the average field efficiency of 72,54%. The results of field observations on the corn seeds planter is the average distance in row planting is 28,57 cm, the average distance between planting rows is 75,37 cm, the number of seeds per planting hole an average of 1 seed, the average planting depth of 4,23 cm, the percentage of seeds growing an average of 80.42% and the percentage of seeds not growing an average of 19.58%. Key words: Seeds planter, TP CSM 16, Hand Tractor.
