Abstract

Many lettuce plants are grown hydroponically because they produce better quality.The problem with hydroponic systems is that the plant roots are submerged in the nutrient solution, therefore it will rot easily due to lack of oxygen in the root area. To overcome this problem, hydroponics with microbubble technology is applied. This research aims to determine the performance of the ventury dual nozzle in producing microbubbles and its effect on the growth and productivity of lettuce plants. This research was carried out by assembling a hydroponic system equipped with a ventury model aerator, measuring bubble characteristics using the image processing method and analyzing plant parameters using variance analysis. Ventury nozzle with a pressure of 260 KPa produces microbubbles measuring between 200 - 300 m and a spray range of 6.13 cm with a resistance of around 3.2-4.6 seconds. The use of a ventury nozzle model aerator increases dissolved oxygen and distributes it evenly in the hydroponic nutrient solution, thereby increasing the growth and yield of lettuce plants.

Abstract

The corn seed sorting tool is a tool used to improve the quality of corn seeds used in the corn plant production process. The corn seed sorting process aims to separate corn seeds based on size and dirt. With the existence of this corn seed sorting tool, it can greatly assist corn farmers in producing high-quality seeds. This research aims to determine the performance of the seed sorting tool in sorting corn seeds using a vibration mechanism. In this research method, the variation of machine rotation speed is carried out at three levels, 1065 rpm, 1300 rpm, and 1400 rpm. Each speed level is tested with different inclination levels, 10°, 12.5°, and 15°. The results of this study indicate that the work capacity is directly proportional to the machine's rotational speed and the inclination angle of the sieve. The best performance in the sorting process is achieved at a machine rotational speed of 1400 rpm and an inclination angle of 15°, resulting in a sorting rate of 99%. Meanwhile, sorting effectiveness can be achieved at a machine rotational speed of 1300 rpm°.

Abstract

Plant cultivation using the NFT (Nutrient Film Technique) hydroponic system is quite widely used by people in urban areas in plant houses. Suboptimal provision of nutrients causes unsatisfactory plant production. Less than optimal provision of nutrients for plants will affect plant production. Cultivation of caisim mustard plants in hydroponic systems will also be beneficial in urban areas where land is very limited. The design of the NFT hydroponic system also affects the provision of nutrients for Caisim mustard plants. This study aims to determine the performance of the NFT hydroponic system (gutter discharge) and the concentration of AB Mix in the cultivation of caisim (Brassica Juncea L.). The method used in this study was a Randomized Group Factorial Design (RAKF) with two treatment factors, namely water flow discharge (Q) and concentration of nutrient solution (N) consisting of three treatments and three replications. The research parameters were plant height, number of leaves, plant fresh weight, plant dry weight and plant productivity. It was concluded that the water flow discharge and concentration of nutrient solution had a significant effect on plant growth, number of leaves and fresh weight of plants.

Abstract

Spectrometer is one of the tools that can produce a spectrum of light with certain wavelengths. A wavelength produced by measurements using a spectrometer will produce absorbance, reflectance and transmittance values. The result of light absorbed by the object is called absorbance, the light reflected by the object is called reflectance, while that which is not absorbed and not reflected by the object is called transmittance.Objective. The purpose of this study are the wavelength, absorbance value, reflectance and its relationship to color in the post-harvest process so that it is expected to be a reference and can provide information about wavelength, absorbance value, reflectance and its relationship to color in the post-harvest process.Methods. Measuring wavelenght, absorbance and reflectanceduring the postharvest process, both before treatment and after treatment. Results. The results obtained are the absorbance value of fresh green coffee of 0.98%, fresh yellow coffee of 0.18% and red coffee of 0.27%. However, after going through the post-harvest process there is a change in the absorbance value where green coffee that has been dried using the yellow honey method has decreased by 0.92% and the black honey method is 0.38% while yellow and red coffee beans have increased at wavelengths ranging from 300-400 nm and 400-500 nm, as well as roasted coffee. While the reflectance value can be seen that fresh green coffee has a reflectance value of 92%, yellow coffee is 89% and red is 69%. However, after going through the post-harvest process where green and yellow coffee that has been dried using the black honey and yellow honey methods has decreased and red coffee beans have increased at wavelengths around 900-1000 nm, as well as roasted coffee, therefore, can be concluded that the post-harvest process causes the absorbance and reflectance values to change at the same wavelength.These findings are expected could provide the information regarding the change of wavelength, absorbance and reflectance during coffee processing.

Abstract

The post-harvest handling of corn involves threshing, the process of separating kernels from the cob. A corn shelling machine without husking offers advantages for both sellers and buyers by allowing manual sorting of good and damaged kernels before threshing. This study evaluates the performance of a no-husk corn sheller used in the Amali District, Bone Regency. Key parameters analyzed include fuel consumption, shelling capacity, percentage of damaged kernels, and cleanliness level at three different rotational speeds (500, 600, and 700 rpm). The results indicate that increasing the rotational speed leads to higher fuel consumption and improved shelling capacity. However, the percentage of damaged kernels decreases with higher speeds, achieving an average damage rate of 0.049%. Additionally, the cleanliness level of the shelled corn reaches an average of 98%, confirming the machine’s efficiency. These findings suggest that optimizing the rotational speed enhances both productivity and output quality, making the no-husk corn sheller a viable tool for post-harvest processing.

Abstract

Virgin Coconut Oil is a pure coconut oil that can be obtained from the extract of fresh and old coconut meat. This study aimed to evaluate the performance of a biofermentor integrated with a fuzzy logic control system and IoT for VCO production. The research involved designing control rules to regulate temperature, testing the IoT system for real-time monitoring, and assessing the biofermentor's performance. The parameters observed were control system response, temperature, yield and moisture content.  Results showed that the fuzzy control system effectively maintained temperature stability, resulting in a higher yield (39.65%) and lower moisture content (0.08%) compared to conventional methods. In addition, the fuzzy control rules are able to regulate the power so that the temperature overshoot is quite small (1%), the settling time is relatively short (9 minutes), the temperature is stable, and the steady state error is 1.02% (with in tolerance limits).

Abstract

The Index of Land Potential (IPL) is a land evaluation method that aims to identify and utilize land according to its potential. Through IPL, it is expected to achieve optimal productivity and land sustainability. This research aims to determine the Paddy Field Potential Index with the IPL weighting method using Geographic Information Systems (GIS) in Gowa Regency. In this research, the method used is a tiered quantitative approach, where each parameter is given an appropriate weight. Overlapping techniques were applied to various maps used to assess land potential, including aspects of slope, soil type, lithology, hydrology, and disaster risk. The results of this study include a land potential index map and a map of paddy field potential in Gowa Regency. In the LMI, the dominating classes are low and very low, covering an area of 156,885.34 ha (72%), while the use of paddy fields in the very high and high potential classes covers an area of 20,604.48 ha (39%). The relationship between productivity and IPL is explained through the equation IPL = 0.1025P + 4.9539 with a value of R2 = 0.7809, which indicates that an increase in IPL can be a guide to increasing the productivity of rice plants..
