Abstract

AbstractThe aim of this research is to develop a Near Infrared (NIR) calibration model based on water content and total carotene that can be used as a standard of ripe fruit. There are three steps of the research. The first step is NIR spectral data aquisition of 60 samples by using NIRFlex N-500. Next step is measuring water content and total carotene from each sample using destructive method. The last step is development of NIR calibration model using (Partial Least Square) PLS and applying pretreatment data Standard Normal Variate (SNV), normalization (N01), dan First Derivative Savitzky-Golay 9 Point (DG1). The result show that water content could be predicted well by applying SNV with R2 (calibration) =0.89, R2 (validation) = 0.88 and RPD = 2.84. Total carotene also could be predicted well by applying DG1 with R2 (calibration) = 0.84, R2 (validation) = 0.77 and RPD = 2.06.Keywords: Fresh Fruit Bunch (FFB) maturity, NIR spectra, calibration model, water content, total caroteneAbstrakTujuan dari penelitian ini adalah untuk membangun model kalibrasi dari kadar air dan total karotenyang dapat dijadikan standar kematangan buah. Terdapat tiga tahapan pada penelitian ini, pertama akuisisi spektrum Near Infrared (NIR) pada 60 sampel menggunakan NIRFlex N-500. Langkah selanjutnya adalah pengujiankadar air dan total karoten tiap sampel secara destruktif. Langkah terakhir adalah pembuatanmodel kalibrasi menggunakan metode (Partial Least Square) PLS dan menerapkan pretreatment data Standard Normal Variate (SNV), normalisasi (N01), dan First Derivative Savitzky-Golay 9 titik (DG1). Hasilmenunjukkan bahwa kadar air dapat diprediksi dengan baik menggunakan SNV dengan R2 (kalibrasi) = 0.89 dan R2 (validasi) = 0.88 dan RPD = 2.84. Total karoten juga dapat diprediksi dengan baik menggunakan DG1 dengan R2 (kalibrasi) = 0.84 dan R2 (validasi) = 0.77 dan RPD = 2.06.Kata kunci: Kematangan Tandan Buah Segar (TBS), spektrum NIR, model kalibrasi, kadar air, total karotenDiterima: 13 Agustus 2014 ; Disetujui: 30 September 2014

Abstract

Ngebel Village is a producer of Klanceng Honey and an ecotourism destination for Ngebel Adventure Park (NAP) in Ponorogo Regency. Klanceng honey produced by the endemic Klanceng bee (Trigona sp.) is the honey that has high selling value (IDR 60,000 per 100ml) and currently, there are 61 farmers with the total of 620 log beehives. So far, production capacity has only met 40% of consumer demand, so efforts to increase the capacity are needed. Efforts and support have been given by the village government to beekeepers through the increasing the number of wooden bee nests (setup) and improving the technology of the honey handling process. One of the critical processes to determine the optimization of the quantity and quality of klanceng honey is the extraction process as a process that determines the level of yield. So far, honey extraction has been done manually using a syringe or filtered with a sieve. The Trigona sp. bee, as a honey-producing bee, has a laver-shaped hive, where the shape of the hive influences its internal structure. The extraction of Klanceng honey can not be done using the existing honey extractors due to the inappropriate structure of the beehive. Dissemination of the centrifugal extractor was aimed to increase honey extraction efficiency and improve its hygiene. The Centrifugal Extractor consists of an extractor tube having a static tube and a rotating tube, a filter tube, a transmission unit and a 0.25 HP electric motor with rotary speed regulator.. The use of this machine results in an increase in yield (increasing of rendemen from 75% up to 83% Klanceng honey) and an increase in organoleptic of honey (aroma, appearance, taste and color) so that the product is competitive in the market.
