Abstract

In this research, the feasibility of using NIR spectroscopy coupled with forward interval partial least squares (FiPLS) regression for nondestructive soluble solids content (SSC) determination in Pondoh snake fruit was investigated. Spectra of snake fruit were acquired using a VIS-NIR USB4000 portable spectrometer in absorbance mode. The SSC was measured using a digital refractometer.  The calibration and validation models were developed using the FiPLS regression using original spectra. The result showed that the optimal combinations of 7 spectral intervals among 11 intervals which selected by FiPLS yielded good results (RMSEC = 0.854783%, rc= 0.96, RMSECV = 0.899828%, rv = 0.95).  Keywords: soluble solids content, absorbance mode, nondestructive method, snake fruit, FiPLS regression, NIR spectroscopy

Abstract

The objectives of this research was to evaluate the feasibility of using NIR spectroscopy and interval partial least squares (iPLS) regression for nondestructive soluble solids content (SSC) determination in snake fruit. Spectra of snake fruit were acquired using a VIS-NIR USB4000 portable spectrometer in absorbance mode. The SSC was measured using a digital refractometer.  The calibration and validation models were developed using the iPLS regression using original spectra. The calibration results showed that the root mean square of cross-validation (RMSECV) of first six subintervals from 582-831 nm was lower than that of the average of RMSECV and these subintervals were selected for developing final iPLS regression. Using the selected subintervals the calibration has high quality of prediction with RPD = 3,35. Keywords: NIR spectroscopy, soluble solids content, absorbance mode, nondestructive   method, snake fruit, iPLS regression

Abstract

Mushrooms are plants that have a nucleus, spores, no chlorophyll and are heterotrophic. Mushrooms can not produce their own food, they get nutrition by way of absorption. Nutrients are absorbed from the mushrooms existing in the organic material in which they live (Alexopoulos and Mims, 1996). Baglog is a media into the growth of mushrooms which comprises a mixture of basic materials such as wood sawdust, rice bran, limestone and so on. The mixture will be allowed to stand for 2-3 days so that all the materials decompose properly. All the material that has decomposed properly inserted into the plastic which will then be compacted. This media must be completely solid to support the growth of mushrooms. Compaction is done by using a press baglog mushrooms (Sunarmi and Saparinto, 2010). Keywords: mushroom baglog, two cylinder, electric motor

Abstract

Kale spinach is a type of vegetable that is widely consumed by people in Indonesia. It’s contains protein, carbohydrates, calcium, iron, sodium, phosphorus, fiber, vitamins A and C. The kale spinach is a low-calorie vegetable. The purpose of this research is to design kale spinach seed planting tool with a semi-mechanical system which power comes from human power, this tool is operated by pulling a lever on the tool so that the tool can work. After the manufacture of kale seed planting is complete, the authors test the performance of the tool capacity, and from the results of the performance test of this tool it can be concluded that it can work well. The results of the performance test of the capacity of this tool to plant water spinach seeds with an area of 0.0005 ha takes 0.007 hours with an average speed of 0.2 m/s, the average seeds that fall per hole are 3 seeds, 98.6% efficiency, The theoretical capacity is 0.072 ha/hour, the effective capacity is 0.071 ha/hour, the percentage of growth is 95%, the average distance between plants is 10 cm, and the average distance between rows of plants is 10 cm.
