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

Rice fields are used as an alternative to achieve food self-sufficiency because they have many advantages such as providing lots of water, land close to rivers, and the ability to choose land for farming. So this research is needed to determine the work efficiency and operational costs of the Jajar Legowo RTP 2040 rice transplanter. So that it can maximize the performance of this planting tool when it is later used by farmers. The aim of this research is to determine the work efficiency and operational costs of the Jajar Legowo RTP 2040 rice transplanter on rice fields in Bone Regency. The procedure used begins with the seeding stage, land processing, and the rice transplanter operation stage. The Jajar Legowo RTP 2040 rice transpanter was operated with a test distance of 10 x 10 m and carried out 3 repetitions using a speed of 2 km/hour on the land according to the planting work pattern. The results of this research obtained a KLT value of 0.257 ha/hour, KLE of 0.193 ha/hour, and field efficiency of 75.15%. Meanwhile, the wheel slip value obtained was 15.42. As for the cost analysis, the fixed costs are obtained at Rp.8.842.988,-/year, while the total variable costs are Rp. 5.154.240,-/year. Basic operational costs obtained are IDR. 13.997.228.-/year.

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..

Abstract

Corn is a staple food for the Indonesian population due to its high carbohydrate content, second only to rice. Estimating corn production before the harvest period is crucial for predicting total production output from a given location. This study aims to develop a production model for corn using Sentinel-2 satellite imagery combined with spectral data from a spectrometer and field measurements. The research involved collecting field data on corn production, downloading Sentinel-2 imagery for the period from December 10, 2022, to February 28, 2023, performing atmospheric correction and image cropping, transforming the data into NDVI and EVI vegetation indices, and analyzing the data using simple linear regression to determine the relationship between the NDVI and EVI indices and corn plant parameters, specifically biomass. The results show a strong correlation between productivity estimates using Sentinel-2 and spectrometer data with field observations. For the Sentinel-2 Vegetation Index, EVI has the highest correlation with productivity at approximately 88%, compared to other vegetation indices at around 80%. For the Spectrometer Vegetation Index, NDVI has the highest correlation at around 83%, while other indices are below 80%. Therefore, Sentinel-2 and spectrometer data can effectively estimate productivity in corn plantations.

Abstract

Post-harvest handling, particularly fermentation and soaking, significantly affects cocoa quality. This study investigates the effects of fermentation duration (3, 5, 7 days) and soaking time (1, 2, 3 hours) on the moisture content of MCC 02 cocoa beans. The fermented beans were sun-dried, and moisture content was analyzed using the wet/dry basis method. Results showed the lowest wet basis moisture content of 55.65% for beans fermented for 3 days and soaked for 1 hour, and the highest of 63.1% for beans fermented for 3 days and soaked for 2 hours. After drying, the control sample had a moisture content of 7.7% (63.5% before drying), while the lowest moisture content for beans fermented for 5 days with 1-hour soaking was 7.95%, and the highest was 10.65% for beans fermented for 3 days with 1-hour soaking, exceeding the SNI standard (6-7%). Temperature fluctuations (28 - 37°C) and weather-dependent drying prolonged the process, resulting in higher moisture content than the standard, indicating the need for controlled drying methods.

Abstract

Coconut water (Cocos nucifera L.) is a natural beverage widely recognized for its high nutritional and health benefits. It contains essential electrolytes such as potassium, magnesium, and calcium, along with various vitamins and antioxidants; however, the quality deteriorates over time during storage. This study compares changes in the quality of young and mature coconut water stored at cold and ambient temperatures over a specific period of time. The research method includes measuring turbidity levels, pH, and total dissolved solids (TDS). The results indicate that both young and mature coconut water experience degradation in quality during storage, although at different rates. Storage at ambient temperature leads to a more rapid decline in quality than cold storage for both maturity types. Additionally, microbial growth is more frequently detected in coconut water stored at ambient temperature, particularly in mature coconut water. This study summarises that the quality of young and mature coconut water is influenced by storage temperature, with mature coconut water deteriorating at a higher rate. These findings can be recommended for storing coconut water at cold temperatures and consuming it shortly after opening it.
