Abstract

Biomass growth can affect the increase of corn crop production. Efforts can be made to produce good biomass growth, one of which is by adjusting plant spacing to ensure even distribution of nutrients to plants. Vegetation indices on sentinel-2 satellite imagery could used to observe the growth of corn plant biomass. The purpose of this study was to determine the relationship between sentinel-2 image vegetation index and corn plant growth parameters at a spacing of 70 x 40 cm, 70 x 20 cm and irregular. This research was conducted through several stages, i.e. (1) field data collection of plant height, biomass and leaf area, (2) downloading sentinel-2 image data for the period of December 10, 2022 - February 28, 2023, (3) atmospheric correction and image cropping, (4) transformation of NDVI and EVI vegetation indices and (5) data analysis using simple linear regression analysis to observe the relationship of NDVI and EVI vegetation indices to corn plant growth parameters. The parameters observed were plant height, biomass and leaf area. Based on growth parameters, planting distance of 70 x 40 cm produced good crop growth. Furthermore, growth parameters and vegetation index values of both NDVI and EVI showed a strong correlations at a spacing of 70 x 40 cm. In addition, the transformation map of the two indicices showed that NDVI vegetation index is categorised in the group of medium greenness, while EVI vegetation index is categorised in the group of high greenes. Based on the research results, NDVI and EVI vegetation indices had a strong relationship with the growth parameters of corn plants at a spacing of 70 x 40 cm. In other hand, spacing of 70 x 20 cm and irregular were categorised as moderate. It is found that corn plant growth parameters (plant height, biomass and leaf area) can be monitored using sentinel-2 satellite imagery.

Abstract

Aquaponic system is a cultivation method that combines fish and plant farming or aquaculture and hydroponics that are mutually beneficial (symbiotic mutualism) at one time. Aquaponic water level control to maintain water volume is still done using conventional methods. Therefore, this research aims to produce a good control system to control aquaponic water levels equipped with an on/off control system and can monitor water levels remotely. This research method includes designing a control system for water level, functional test and performance test of the control system to aquaponics as well as data loss test and network delay to Thinger.io platform. The parameter observed was the water level. The results showed that the on/off control system was able to regulate the water level with no overshoot, the settling time reached for a height of 20 cm was 9 minutes, a height of 25 cm for 22 minutes and for a height of 30 cm for 34 minutes and the steady state error that occurred was still within the tolerance limit. The IoT system using the Thinger.io platform implemented is able to send data and store data during the testing process, and the Thinger.io platform can monitor water levels remotely and provide data in excel format. The test results of lost data with an average of 1.81% and delay testing with an average of 0.88%, based on data mapped every 6 hours, the largest percentage of lost data and delay occurs at 00.00 -06.00 GMT +8.

Abstract

Postharvest handling and coffee processing must be carried out based on SNI standards to produce good quality and to increase selling value. In Tana Toraja Regency, there are various UKM engaged in the coffee processing industry but not many have analyzed the quality of the coffee produced. The purpose of this research is to know the postharvest handling and processing of coffee bean at UKM Akarosta and compare the proper postharvest handling process of coffee beans based on SNI standards. The results showed that the postharvest method carried out by farmers in Pasang Village, South Makale District, Tana Toraja Regency is a semiwash method which included harvesting, sorting, peeling fruit skins, washing, drying then stripping horn skins, sorting, roasting, grinding and packaging by UKM Akarosta. The postharvest process carried out by farmers has met with SNI. The quality of the coffee beans produced has met the SNI standard quality of coffee beans No. 01-3542-2004.
