The purpose of this study was to analyze the nutrient content of POC produced from household waste using the stacked bucket method. This research was conducted for 3 months from September to November 2020. This research is a descriptive study. The first process is the process of making organic fertilizer from household waste which is fermented in a stacked bucket for 2 months. Leachate from organic waste is dried in the sun for one month or until the leachate is blackish in color and has no more subtle aroma. The finished POC is sampled and tested in the laboratory to determine the content of micro and macro nutrients as well as organic C. To measure the content of macro and micro nutrients, the test material used was Kjeldahl for nitrogen content while P, K, Fe, Mn, Cu, Zn, S, Ca, Mg, Na used spectrometric wet oxidation method and the content of C-organic by spectrophotometric method. The test results showed that the POC of household waste contained 0.08% total N, 0.07% total P, 0.28% total K, 5 ppm total Fe, 0.4 ppm total Mn, 0.0 ppm total Cu, Zn total 0.6 ppm, total S 0.5%, total Ca 165.0 ppm, total Mg 106.9 ppm, total Na 172.7 ppm, organic C 1.06%, and C/N ratio 13.27.
Non-cultivated local rice is known to have high resistance to various environmental stresses. This resistance is inseparable from the role of symbiotic and non-symbiotic rhizosphere bacteria that live in the root rhizosphere. This study aims to isolate and study the potential of rhizobacteria that live around the roots of non-cultivated local rice plants. This research is exploratory research to obtain rhizobacterial isolates that can stimulate plant growth and development and can be applied to cultivated rice plants. Soil samples were taken from Mimi Baru Village, Jagebob District. Sampling was carried out aseptically. Isolation was carried out using the multilevel dilution method. Isolates grown in NA media were then subcultured to obtain pure isolates. The isolates obtained were then characterized morphologically according to Bergey's Manual of Determinative Bacteriology and characterized microscopically. Based on the results of this study it can be concluded that there were 12 bacterial isolates in the local rice "Cempo Laut" which were suspected to be Bacillus and Pseudomonas. The results of this study need to be tested further to determine the effect on plant growth and development.
Phytotoxicity test of probiotic bacteria was carried out to determine its effect on the germination of jack bean seeds (Canavalia ensiformis L). The study was conducted in February to March 2017, at the Seed Health Laboratory and Seed Center of the Bogor Institute of Agriculture. The study was designed in a Randomized Block Design with seven treatments and three replications. The test results showed that three pairs of probiotics were toxic and three other pairs of probiotics that were not toxic to the growth of Canavalia ensiformis. The three pairs of probiotics that are not toxic are AcCKB20-P24 (D1), AcCKB4-B28 (D3), and AcCKW5-P24 (D4). The three pairs of probiotics that are not toxic are recommended for use in making bio-organic fertilizers for Canavalia ensiformis.
Kegiatan pengabdian ini bertujuan memberdayakan masyarakat Kelurahan Kamundu khususnya mereka yang kesehariannya sebagai ibu rumah tangga, untuk dapat mengolah ikan kakap menjadi beberapa produk makanan, sehingga memenuhi kebutuhan protein hewani khususnya bagi anak – anak. Ikan dapat dioleh menjadi beraneka ragam menu makanan baik sebagai lauk maupun sebagai camilan antara lain, bakso, nugget, sosis, kerupuk, abon, dendeng, perkedel dan lain sebagainya. Target yang ingin dicapai dalam kegiatan pengabdian ini berupa adanya tambahan pengetahuan dan keterampilan bagi masyarakat kelurahan Kamundu dalam mengolah ikan khususnya ikan kakap menjadi berbagai jenis makanan. Metode yang dilakukan dalam kegiatan pengabdian ini berupa motivasi dan sosialisasi kepada masyarakat, kemudian dilanjutkan dengan pelatihan dalam pengolahan ikan kakap menjadi aneka produk makanan berupa bakso, sosis dan perkedel. Hasil dari kegiatan pengabdian ini adalah masyarakat cukup antusias dalam mengikuti seluruh kegiatan ditunjukkan dengan peran serta peserta mengikuti dan mempraktektan seluruh pembuatan produk.
