“…Komoditas buah naga dalam pengembangan agribisnis mempunyai prospek yang cerah untuk peluang ekspor dan pasarnya masih terbuka lebar serta memiliki potensi yang sangat baik untuk pasar di dalam negeri (Chusna, 2011). Djamila et al (2010) mengemukakan bahwa kegiatan budi daya buah naga di Indonesia sangat menguntungkan karena disamping memberi keuntungan secara ekonomi pada petani, hal ini juga akan mengurangi impor buah, bahkan ada kemungkinan untuk menembus pasar ekspor. Tahun 2006, total produksi buah naga dari perkebunan di Malang, Yogyakarta, Semarang, Pasuruan, Jombang dan Klaten sebesar 1 341 ton/tahun.…”

Aspek panen dan pascapanen buah naga putih penting untuk diketahui. Kegiatan penelitian dilaksanakan di Sabila Farm, Sleman, Yogyakarta pada bulan Februari–Juni 2013. Hasil menunjukkan bahwa budi daya buah naga putih yang diterapkan di Sabila Farm secara keseluruhan sudah cukup baik sehingga dapat menghasilkan mutu buah yang mampu bersaing dengan perusahaan lain. Panen tidak dilaksanakan secara serempak setiap bulan, tetapi berdasarkan pesanan konsumen dan keperluan agrowisata. Pemanenan buah naga putih oleh tenaga kerja dilakukan secara manual sesuai dengan karakteristik umur panen. Tenaga kerja panen memiliki keterampilan yang cukup baik sehingga kerusakan hasil panen akibat kerusakan mekanis jarang terjadi. Kerusakan hasil panen disebabkan oleh hama burung dan ayam. Berdasarkan uji korelasi dan regresi, produktivitas dan jumlah bunga dipengaruhi oleh curah hujan dua bulan sebelumnya. Pengelolaan pascapanen buah naga putih di Sabila Farm secara keseluruhan sudah cukup baik, tetapi grading dan pengemasan masih perlu perbaikan.

“…Kebutuhan buah naga di Indonesia masih mengalami kekurangan sehingga masih bergantung pada produk import sebanyak 6.696 ton pada tahun 2012 [12]. Budidaya tanaman buah naga memberi keuntungan yang cukup besar seperti meningkatkan perekonomian petani hingga memungkinkan membuka peluang untuk menembus pasar ekspor [13].…”

Dragon fruit is one of the fruit commodities included in the type of cactus which can grow in arid areas and less productive land such as in Pangandaran Regency. Knowledge of the surrounding community about dragon fruit is good, but knowledge about cultivation and propagation of dragon fruit is still lacking. So that the supply of plant material that is still difficult to obtain and requires high costs for farmers because of the increasing number of enthusiasts in the cultivation of dragon fruit. To resolve this problem such as by providing the planting material independently. The technique of plant propagation of dragon fruit plants such as by vegetative propagation which can improve the quality of the yield and economic value of dragon fruit. To increase public awareness and interest can be done by providing assistance in the plant propagation technique of dragon fruit plants. The area used as a partner in this activity is Cintaratu Village, Parigi District, Pangandaran District. The method used in the mentoring activity is the treatment of dragon fruit multiplication, propagation practice, and the making of planting demonstration plots of tanama. Based on the results of the enrichment shows that the enthusiasm and high interest of the community in getting knowledge and information about the propagation techniques of dragon fruit plants in the area and willing to cooperate in the next program.

NIR spectroscopy and chemometrics were assessed to determine the total soluble solids (TSS) and hardness of the dragon fruit nondestructively. Dragon fruit reflectance (n=117) were measured nondestructively by FT NIR spectrometer, and after that TSS and hardness of dragon fruit were measured destructively with digital refractometer and rheometer, respectively. Six spectra pretreatments and some number of PLS factors were applied to analyze the chemometrics effect to NIRS accuracy in predicting TSS and hardness of dragon fruit. The values of reflectance spectra of dragon fruit are high in 1000-1400 nm and after that decrease gradually. On the contrary, the values of absorption spectra are low in 1000-1400 nm, but in 1400-2500 nm the values are high with high variation. The hardness range of dragon fruit is 8.73-24.91 N and TSS of 9.20-17.60 brix. Reflectance spectra is better than absorption spectra in predicting TSS and hardness of dragon fruit. Only detrending spectra pretreatment increased the accuracy of NIR spectroscopy in predicting TSS of dragon fruit. However, there is no spectral pretreatment that can improve accuracy in predicting dragon fruit hardness. Increasing the number of PLS factors may increase the accuracy for a while but after that it decreases. The best chemometrics to determine TSS of dragon fruit is using detrending pretreatment of reflectance spectra and 16 PLS factors (r=0.93, SEP=0.66 brix, RPD=2.09). For hardness, the best chemometrics is using original reflectance spectra and 17 PLS factors (r=0.89, SEP=1.75 N, RPD=2.02). NIR Spectroscopy and chemometrics can be used to predict TSS and hardness of dragon fruit accurately and nondestructively.
