Abstract

Ikan yang dijual di pasar tradisional mengalami kendala dalam mempertahankan kesegarannya. Hal tersebut disebabkan oleh mikroorganisme khususnya bakteri yang hidup pada ikan tersebut. Cakalang (Katsuwonus pelamis L.) merupakan ikan yang berasal dari laut timur Indonesia dan dikenal  sebagai salah satu ikan yang banyak diminati masyarakat khususnya di Singaraja, Bali. Penelitian ini bertujuan untuk mengetahui jumlah koloni bakteri yang tumbuh pada insang ikan cakalang yang berasal dari pedagang ikan di tiga pasar tradisional di kota Singaraja, Bali. Adapun sampel dari penelitian ini antara lain ikan cakalang yang berasal dari pasar anyar, pasar banyuasri dan pasar banyuning. Perhitungan jumlah bakteri menggunakan metode Standard Plate Count. Hasil penelitian ini menunjukkan rata-rata jumlah koloni bakteri yang ditemukan pada insang ikan cakalang di ketiga pasar cukup bevariasi. Bakteri terbanyak berjumlah 4,20 x 107 CFU/ml ditemukan pada pasar banyuasri dan tersedikit ditemukan pada pasar anyar yaitu 2,10 x 107 CFU/ml (rata-rata dari pengenceran 10-6). Bakteri gram negatif mendominasi pada setiap ikan cakalang yang dijual di pasar tradisional kota Singaraja.

Abstract

The purpose of this research were to determine the differences between organic and inorganic fertilizers in the growth of gemitir (Tagetes erecta) seen from the height and number of leaves. This research used a qualitative approach. This research was conducted by observing 56 fruit trees which were cultivated in two different beds and applied in organic and inorganic fertilizers at the same concentration and amount. To reduce the factors that inhibit plant growth, shade from plastic is made. Watering and maintenance were carried out every day with the same amount. Observations regarding plant height and number of leaves were carried out starting from week 1 to week 7. Data analysis was done by searching for the mean and percentage difference in yield from plant height and number of studies showing that the average plant height using organic fertilizer was 18.96 cm and organic fertilizer was 20.44 cm. This showed that there was a difference of 7.24% inorganic fertilizer higher than organic fertilizer. While the average number of leaves of gemitir plants added with organic fertilizer was 26.00 strands and inorganic fertilizers as much as 28.40 strands. The difference between the two was 8.5%, meaning that the use of inorganic fertilizers produces more leaves 8.5% or an average of 2-3 strands compared to organic fertilizers.
