Abstract

Cilok is one of the traditional food in Indonesia. Cilok is a popular treat among Indonesians due to its good taste and cheap price. To make it last longer, cilok is sometimes added with preservative. However, such attempt will endanger consumers if dangerous preservatives are used, such as formaldehyde and borax. Their usage in food preservation may negatively impact consumers’ health. The aim of this research was to develop an alternative, natural preservative for fish cilok. The preservative would be chitosan. The method used is an experiment that is by making a chitosan solution from the shrimp skin waste. In the experiment, chitosan was extracted from shrimp waste. A 1,5% chitosan concentrate was used. Its preservation potency was tested by giving three treatments towards fish cilok: fish cilok with 1,5% chitosan coating; fish cilok mixed with 1,5% chitosan solution and fish cilok without chitosan. The three treatments were observed and an organoleptic test was performed according to the preservation time in a room temperature on Day 1, 2, 3, 4 and 5. The parameters tested during the experiment were taste, color, odor and texture of fish cilok. The research results showed that fish cilok coated with 1,5% chitosan solution lasted longer than fish cilok without or added with chitosan. Keywords: chitosan, natural preservative, fish cilok

Abstract

Tujuan yang dicapai dalam penelitian ini adalah untuk meningkatkan kecerdasan logika matematika anak melalui permainan balok usia 5-6 tahun di TK Amanah Kecamatan Sumbersari Kabupaten Jember. Jenis Penelitian yang dipakai yaitu penelitian Tindakan Kelas (PTK) dengan variabel terkait dengan mamakai kegiatan permainan balok yang meliputi empat langkah yaitu: perencanaan, pelaksanaan, observasi, dan refleksi. Analisis data dalam penelitian ini dengan menghitung skor kesuksesan atau ketuntasan secara klasikal. Berdasarkan analisis data yang dilakukan, dengan diterapkannya kegiatan permainan balok mulai dari observasi awal dengan presentase 53%, pelaksanaan siklus I 69% dan siklus II meningkat menjadi 80% kecerdasan logika matematika anak dapat meningkat dari belum berkembang sampai berkembang. Sehingga bisa mencapai standart yang diharapkan. Dengan demikian dapat dikatakan bahwa permainan balok dapat meningkatkan kecerdasan logika matematika anak usia 5-6 tahun.
