Abstract

The research aims to observe the influence of harvesting time on the change of calcium oxalate (CaOx) content and crystal density in Porang corms. The corms were harvested at different times, i.e., (1) two weeks before the plants shed (R0-1), (2) when the plants shed (R0), and (3) two weeks after the plants shed (R0+1). CaOx was obtained using the modified extracting method. Microscopic observations were obtained from the slices of the edge and center part of porang corms. Parameter observed including CaOx content, corm weight, shape, and density of CaOx crystal. CaOx content and crystal density in corms were analyzed using One way ANOVA. If the results are significant, it will be followed by Tukey Test α 0.05. In the meantime, the relation between CaOx content and corm weight was analyzed using Correlation Test Bivariate. The results showed that CaOx content was relatively higher in porang corms, i.e., 15.98 ± 0.60g/100g. On the other hand, the increasing of CaOx content might improve corm weight. The total density of druse, styloid, and prism crystal was pretty high in corms obtained when the plants shed compared to another harvest time, i.e., 1,494 ± 286; 31,280 ± 17,406 and 6,256 ± 1,533 crystals/cm2 . Raphide crystal density, by contrast, increased in corms obtained after the plants shed, i.e.,1,656 ± 368 crystals/cm2 . Total CaOx crystal density in the edge parts of corms harvested when the plants shed was proportionately higher than in the other harvest times, i.e., 12,292 ± 4,687.89 crystals/cm2 . In contrast, CaOx crystal densities in the center parts of corms were not much different at three harvesting times. The density of druse and prism crystals was somewhat higher in the center part of corms than in the edge parts. In opposition to, the density of raphide and styloid crystals was fairly higher in the edge part of corms than it was in the center parts. However, only raphide crystal density found in the edge and center part of corms was significantly affected by harvest time from all these results.

Abstract

Kalimantan Utara merupakan salah satu provinsi yang berbatasan langsung dengan Negara Malaysia perlu didukung untuk dapat berkembang sehingga masyarakatnya tidak tergantung dengan produk-produk pertanian dari daerah Negara lain. Salah satu hal yang bisa dilakukan guna mendukung hal tersebut adalah dengan menerapkan program pertanian terpadu. Desa batu kajang merupakan salah satu desa terluar di wilayah Kalimantan Utara dan sebagian besar masyarakatnya bermata pencaharian sebagai petani tanaman hortikultura, permasalahan yang ada di desa Batu Kajang yaitu masyarakatnya belum banyak yang memiliki usaha sampingan lain untuk menunjang ekonomi keluarga sehingga masyarakat disana hanya bergantung pada pendapatan hasil panen yang dijual kepasar. Kegiatan pengabdian kepada masyarakat ini dilaksanakan di Desa Batu Kajang Kabupaten Malinau Provinsi Kalimantan Utara. Mekanisme kegiatan dibagi kedalam beberapa tahapan yaitu survei, sosialisasi, pelatihan dan evaluasi kegiatan. Kegiatan pelatihan merupakan kegiatan puncak dari PKM yaitu bimbingan teknis kepada masyarakat mengenai pembuatan instalasi hidroponik dan pembuatan kolam terpal untuk ikan lele. Tahapan pelatihan terdiri dari beberapa tahapan diantaranya pembuatan instalasi hidroponik, Kegiatan pengabdian masyarakat berjalan dengan baik ditunjukkan dengan antuasisme masyarakat desa batu kajang yang sangat besar dalam mengikuti pelatihan tersebut. Budidaya tanaman secara hidroponik dan ternak lele merupakan salah satu solusi terbaik sebagai usaha sampingan dalam meningkatkan pendapatan ekonomi keluarga.

Abstract

Chemical compounds are presumed to interact with each other and potentially affect the crystal development of porang tubers. This study focused on glucomannan and calcium oxalate (CaOx) as chemical compounds found in porang. Crystal development was analyzed by microscopic observation. The tuber tissue was used for microscopic slides and was harvested two weeks before the plants lost their leaves, when the plants lost their leaves, and two weeks after the plants lost their leaves. The CaOx and glucomannan content was measured using a modified extraction method. The increasing of CaOx content tends to increase the number of CaOx crystals. The analysis showed that the crystal density could affect the increasing of tuber weight possibility. There was a development process in raphide crystals that showed by different sizes at three harvest times, which the others were not. The results also indicated that glucomannan might influence the crystal density and the CaOx content. It can be concluded that glucomannan can potentially induce CaOx synthesis and crystal count increase. Keywords: Caox, Crystal, Development, Glucomannan, Interact, Porang.
