Indigenous vegetables have become popular in recent Indonesian diet, but agronomic and economic studies on these crops are limited. The objective of this research was to investigate the cultural technique of indigenous vegetables, their uses and economic importance in Keywords: Cosmos caudatus, Limnocharis flava, local knowledge, Pilea melastomoides, Solanum americanum ABSTRAKPopularitas sayuran indigenus terus meningkat di Indonesia, namun studi agronomi dan ekonominya masih terbatas. Penelitian bertujuan mengkaji budidaya, pemanfaatan dan nilai ekonomis sayuran indigenus di Jawa Barat, Indonesia. Penelitian pendahuluan dilakukan di pasar di wilayah Bogor. Penelitian mendalam dilakukan dengan mewawancarai pedagang, petani dan konsumen, serta mengamati di lahan petani di tiga kabupaten yakni Bogor, Cianjur dan Tasikmalaya untuk empat sayuran indigenus utama yakni genjer (Limnocharis flava (L.) Buchenau), kenikir (Cosmos caudatus Kunth.), leunca (Solanum americanum Miller) dan poh-pohan (Pilea melastomoides (Poir.) Wedd.). Studi menunjukkan bahwa sayuran indigenus diproduksi secara intensif dan semi intensif, serta dijual di pasar setiap hari, walaupun penduduk setempat tidak mengkonsumsi secara teratur. Sayuran indigenus mengisi celung pasar kurang dari 5% dan memenuhi kurang dari 10% kebutuhan sayuran rumah tangga. Konsumen memilih sayuran indigenus karena sudah terbiasa mengkonsumsi, harga terjangkau, disukai anggota keluarga, ketersediaan dan kemudahan mengolah. Secara umum, anggota keluarga muda (usia < 30 tahun) lebih jarang membeli sayuran indigenus dibanding yang lebih tua (usia > 30 tahun), kemungkinan disebabkan keterbatasan informasi nilai guna, adanya aroma asing, dan ketersediaan sayuran lain.

<p>ABSTRACT</p><p><br />The objective of the experiment was to investigate the physical and chemical characteristic of eight genotypes of papaya i.e. IPB1, IPB 2A, IPB 3, IPB 3A, IPB 4, IPB 7, IPB 8, and IPB 9 on two stages of ripening period based on percentage of the yellow area of fruit peel (75% yellow and 100% yellow). The fruits were <br />picked at 25% yellow of fruit peel colour. The experiment was conducted in split plot wi th completely randomized block design. The main plot was ripening periods of 75% and 100% ripe, while the genotypes were taken at subplot. There was no significant different on physical and chemical characteristics between papaya at stadium 75% and 100% yellow. Flesh firmness of IPB 9 was better than IPB 1, IPB 4 and IPB 8. Ascorbic acid content of IPB 4 (107.36 mg/100 g) was higher than that of IPB 2A and IPB 3A. Carotenoid content of IPB 4 (29. 73 mg/100g) was higher than that of the other genotypes.</p><p><br />Key words: Carica papaya, physical characteristic, chemical characteristic, ascorbic acid, carotenoid</p>

Eggplant is one of the most widely cultivated vegetables in the world and has high biodiversity in terms of fruit shape, size, and color. Therefore, fruit morphology and nutrient content become important considerations for both consumers and breeders who develop new eggplant-based products. To gain insight on the diversity of eggplant metabolites, twenty-one eggplant accessions were analyzed by untargeted metabolomics using GC-MS and LC-MS. The dataset of eggplant fruit morphologies, and metabolites specific to different eggplant fruit accessions were used for correlation analysis. Untargeted metabolomics analysis using LC-MS and GC-MS was able to detect 136 and 207 peaks, respectively. Fifty-one (51) metabolites from the LC-MS analysis and 207 metabolites from the GC-MS analysis were putatively identified, which included alkaloids, terpenes, terpenoids, fatty acids, and flavonoids. Spearman correlation analysis revealed that 14 fruit morphologies were correlated with several metabolites. This information will be very useful for the development of strategies for eggplant breeding.

True Shallot Seed (TSS) of shallot is shallot seed origin as solution of seed availability problem. Generally, farmers still use bulb seed for shallot production. This is because the aspect of shallot cultivation using TSS seed is still to be reviewed. The aims of this research is get information of performance some varieties of TSS shallot compared to bulb seed of Bima Brebes. This research was conducted in the experimental field of Pasir Sarongge IPB, Cianjur in a Randomize Complete Block Design Group by one factor for with three replication. TSS varieties used Bima Brebes (TSS), Tuk tuk, Pikatan, Tajuk, BM 8705, Sanren, and Manjung compared to bulb seed of Bima Brebes. The result showed variability of color and bulb characters on TSS shallot. Variety of Sanren has leaf length, pseudostems diameter, leaf diameter, and number cloves of clump are higher than Bima both of TSS and bulb seed. The dry weight of clump variety for Sanren, Manjung, and BM 8705 showed not significant to bulb seed of Bima Brebes.

The information of secondary metabolite compound from underutilized Indonesian fruits are still limited including rambai ( Baccaurea motleyana Müll.Arg.), nangkadak ( Artocarpus nangkadak or A. heterophyllus x A. integer ), rambutan ( Nephelium lappaceum L.) and Sidempuan salak ( Salacca sumatrana Becc.). To identify the secondary metabolite, we used GC-MS (gas chromatography-mass spectrometry) and LC-MS (liquid chromatography-mass spectrometry) analyses. The accessions/varieties numbers used in this analysis including two accession for rambai, three accessions for nangkadak, four varieties for rambutan and three accessions for Sidempuan salak. All sample were collected from edible part such arilode/carpel and also rind for only rambutan. Based on, spectral data showed common and specific secondary metabolite compounds in each commodity. Preliminary GCMS analysis from the dataset obtained specific secondary metabolites contained in rambai; Decanoic acid, 1-Decene, Methyl salicylate and Stearyl alcohol, nangkadak; β-Cyclocitral, 2-Furanmethanol and Linoleic acid, rambutan; Citraconic anhydride, 3,5-Dideuteropyridine-4-carboxylic acid, Isobutyl formate and n-Methyl-D3-Aziridine, and Sidempuan salak; 5-Formyl-2-furfurylmethanoate, 2-Methoxy-4-vinylphenol and Tiglic acid.

PENDAHULUANTerung (Solanum melongena L.) merupakan sayuran yang bernilai ekonomi tinggi dan dapat memberikan manfaat bagi kesehatan manusia. Buah ini dikonsumsi diseluruh dunia dalam berbagai warna, bentuk dan ukuran (Akanitapichat et al., 2010). Terung telah dibudidayakan secara luas di daerah tropis dan subtropis, terutama di Asia (Sathappan et al., 2012) dimana beberapa negara produsen terbesar antara lain adalah Cina, India, Mesir, Turki dan Indonesia. Tanaman ini memiliki hasil produksi global sebanyak lebih dari 32 juta ton dengan (Begum et al., 2013
