Abstract

This study aimed to determine the effect of granule growing media on growth and yield of vegetables in ahidroponic wick system. The design of this study used Randomized Complete Block (RCB) with factorialarrangement and three replications. The first factor consisted of three levels : kale (S1), spinach (S2), andmustard (S3). The second factorwere the size of the granules with four levels : 12mm (M1), 6mm (M2), 4 mm(M3) and husk char (M4) as a control. Each plant was grown in a wicked pot. There were 12 treatmentcombinations, with three replicates. Parameters observed were physical properties of the media,evapotranspiration, number of leaves, growth, biomass, and yield. Data was analyzed using the Analysis ofVariance (ANOVA) 1%and 5%levels of significance, followed by LSDcomparision. Results showed that therewasno significant interaction betweenmedia and types of plant. However; sizes of media significantly affected theevapotranspiration, growth, biomass, and yield.Keywords:Wicked, hydroponics, granules, media, vegetables

Abstract

The aim of this research is to know the effectiveness of intermittent irrigation and water productivity analysis, analysis of optimum irrigation interval on plant material of mixed solids of digestat and soil mixture, analysis of optimum combination of digestat solid and soil for plant, and growth and yield analysis Pak Choi plant production. The research was conducted at Greenhouse Plastic Department of Agricultural Engineering Faculty of Agriculture, University of Lampung in November 2016 until December 2016. This research uses two factors of observation, namely Composition of Planting Media and Interval of Irrigation Time. This research used 4 mixed treatment of plant media composition, that is D0 (Digestat 0%: Soil 100%), D1 (Digestat 20%: Soil 80%), D2 (Digestat 40%: Soil 60%), and D3 (Digestat 60% : Soil 40%). Each mixture of media was done 3 repetitions, so that 12 pots were observed. The results showed that the combination of planting medium D1 (Digestat 20%: 80% soil) resulted in a high enough on pak choi of 122.7 grams, while for treatment result D0, D2 and D3 there was a less significant difference. The provision of irrigation water with intermittent irrigation does not significantly affect the growth and yield of Pak choi plant. Longer water delivery intervals still provide a good effect on the results of pak choi plant production due to the addition of solid digestat on the planting medium. The highest water use productivity was achieved by treatment D1 with an average of 774 g /m3. Keywords : Digestat, Intermittent Irrigation, Media Planting, and Pak Choi.

Abstract

Study on drying robusta coffee beans using a solar dryer dome was conducted to support the improvement of coffee bean quality in Lampung Province. This study aims to determine and compare the effects of thickness and drying methods (solar dryer dome and sun drying) on the drying characteristics of robusta coffee beans. The parameters observed were temperature, humidity, weight loss, moisture content, and drying rate. The research results indicate that the reduction in coffee bean moisture content in the solar dryer dome occurred more rapidly than with sun drying. The drying process took 10 days using the solar dryer dome method and 21 days using the sun drying method. ANOVA results on day 10 indicate that the variations in thickness and drying methods significantly affected the moisture content of the coffee beans. LSD results show that the effects of the treatments differed significantly from one another. The treatment using a solar dryer dome with a single-layer thickness yielded the lowest moisture content at 10.2% (wet basis).

Abstract

Water scarcity and low surface irrigation efficiency are major constraints to leafy vegetable productivity in dryland farming. Capillary mat-based irrigation offers a solution through efficient water distribution to the root zone. This study aimed to analyze capillary irrigation efficiency using a cocopeat and rice husk charcoal mixture (1:1) on three leafy vegetables (pakcoy, lettuce, caisim), and to compare the effects of capillary mat lengths of 50% (M1) and 100% (M2) on water use efficiency and plant productivity. The experiment employed a Split-Plot Design within a Completely Randomized Design with three replications (18 experimental units). Measured parameters included environmental conditions (temperature, RH, VPD), nutrient quality (pH, EC, TDS), plant growth (height, leaf number, canopy area, root length, root fresh weight), yield (shoot fresh weight), water consumption, and water productivity.  The results showed that M2 provided a larger water supply than M1 but did not show a significant difference in water use efficiency. Average water productivity for M1 and M2 was 48.69 g/L and 49.86 g/L, respectively. Plant type influenced yield, with caisim producing the highest shoot fresh weight (92.3 g) under M2K3, while lettuce produced the lowest (38 g) under M1K2. Root parameters did not show a consistent interaction pattern between mat treatment and plant type. Economically, M1 was more efficient, with costs Rp10,640.00 lower per bed unit compared to M2. This study recommends using a 50% capillary mat (M1) for pakcoy and lettuce cultivation. Future research can be improved by selecting plants with uniform harvest periods, applying an automated microclimate control system, and utilizing high-precision water level sensors.
