Abstract

The aim of this study is to analyze the potential of sand as a planting medium with the addition of cocopeat, obtain the dose of liquid organic fertilizer for sand media, and find the suitable combination of cocopeat for sand media. The method used is a Complete Randomized Design (CRD) Factorial with 2 factors. The first factor is the combination of planting media (sand and cocopeat) and the second factor is the dose of liquid organic fertilizer. The first factor consists of 3 levels: M1 (sand and cocopeat), M2 (sand and cocopeat mixed), and M3 (cocopeat and sand). Each planting medium has a height of 11 cm. The second factor has 3 levels: P1 (LOF 10 ml/l), P2 (LOF 20 ml/l), and P3 (LOF 30 ml/l). The initial stages carried out in this research include preparing the planting media, seed sowing (for approximately ±16 days), transplanting, and maintenance (watering and fertilization). Observations include monitoring every 3 days (plant height, number of leaves, and leaf width) and final observations (total weight of fresh mustard plants, weight of upper and lower mustard plant parts). The planting media (sand, cocopeat) influenced all parameters. The optimum dose of liquid organic fertilizer is a dose of 30 ml/liter. The most optimal interaction of planting media factors with the dose of liquid organic fertilizer is sand media, cocopeat, and a dose of 30 ml (M1P3) with an average total fresh weight of 4.14 grams. Keywords: Cocopeat, LOF, Planting media, Sand.

Abstract

This research aims to detect flood susceptibility using the Topographic Wetness Index (TWI) and create a flood susceptibility map in the Way Katibung Sub-watershed using the Topographic Wetness Index (TWI). This study employs the Topographic Wetness Index (TWI) method with observation parameters including land slope, soil type, land elevation, rainfall, and land use. The results show that the most influential parameter on the Topographic Wetness Index (TWI) is the land slope. Therefore, TWI can be used to detect flood susceptibility in the Way Katibung Sub-watershed, which is predominantly flat. Areas with the lowest average TWI value of 6.35 have no potential for flooding, whereas areas with average TWI values of 10.94 and 13.95 are the most susceptible to flooding. The flood-prone areas are primarily located near river streams, such as Mekar Sari, Sumber Agung, Talang Way Sulan, Karang Pucung, Banjar Sari, Purwodadi, and Pamulihan in Way Sulan District. Keywords:  Flood Puddle, Sub-DAS Way Katibung, TWI, Vulnerability.

Abstract

The aim of the research was to study the effect of the volume of growth media and nutrient EC (Electrical Conductivity) on the yield and productivity of melon plants (Cucumis melo L.), using a hydroponic wick system.  This study employed a Randomized Complete Design (RCBD) with a factorial arrangement consisting of 2 factors.  First factor consisted of a 3 level growth medium volume per pot namely 5 liters (M1), 14 liters (M2), and 34 liters (M3).  The second factor was a 4 level nutrient EC, including 1.5 mS/cm (P1), 2.5 mS/cm (P2), 3.5 mS/cm (P3), and 4.5 mS/cm (P4).  Each treatment combination used 3 replicates to achieve 36 experimental units. The results showed that the treatment of the 34-liter growth media (M3) yielded high fruit weight of 1.40 kg and the highest water productivity of 37.90 kg/m³. The planting media volume treatment (M) significantly affected parameters namely stem diameter, fruit weight, sweetness level, fruit circumference, and water productivity, but not for other parameters. Meanwhile, the fertilizer EC treatment (P) significantly affected plant height, sweetness level, and fruit circumference, but not for other parameters.  If fruit weight is used as the criterion, the optimum choice was M3P1 (34 liter media volume and 1.5 mS/cm EC). Keywords: Electrical Conductivity, Hydroponics, Melon, Rice Husk Charcoal, Wick System.

Abstract

This research aims to design, manufacture and test a parallel type smoker which has an output that can be controlled and has uniform temperature in each smoker cabinet. In this research, design, assembly, testing and temperature regulation were carried out. This parallel type smoker has 3 main parts, namely the combustion stove, inlet pipe, and smoking cupboard. In the inlet pipe there is a faucet which functions as a control for the smoke output and temperature from the combustion stove to the smoking cupboard. In terms of testing, this tool was tested in several stages, namely trial 1, trial 2, and performance test. After the test is complete, the final stage is carried out, namely equalizing the temperature in each cupboard. The trial phase 1 was carried out with treatment on the operation of the smoke cupboard. Where the stages of operation of all cupboards are carried out simultaneously, then operation of 2 cupboards is carried out and one path is closed alternately. The results showed that the tool experienced problems in the form of unstable temperatures and leaks in the smoker cupboard, so it required patching with silicon. After design improvements have been made, trial 2 and performance testing are continued. Trial 2 was carried out to find out whether the tool still had problems or not before carrying out a performance test. The treatment for trial 2 was the same as that given during trial 1. As a result, the device had no leaks and the temperature was stable and the device was ready to operate at the 15th minute. After that, a performance test was carried out which had the same stages as trials 1 and 2. This is intended to see whether the tool is in accordance with the results during testing or not. After the performance test is carried out, the final stage is to equalize the temperature in each cupboard to produce the same and stable temperature. This equalization is done by adjusting the opening of the faucet valve on the inlet pipe. The results obtained were a parallel type smoker which had 3 smoking cabinets with the same temperature around 37oC. This temperature can used for low smoking temperature.Keywords: Design of Smoker, Parallel, Temperature.
