Abstract. Koesoemawardani D. Afifah LU, Herdiana N, Suharyo AS, Fadhallah EG, Ali M. 2021. Microbiological, physical, and chemical properties of joruk (fermented fish product) with different levels of salt concentration. Biodiversitas 22: 132-136. Joruk is a fermented fish product originated in Ogan Komering Ulu Timur, South Sumatra, Indonesia. The aim of this study was to determine the effect of salt on the microbiological, physical and chemical properties of joruk. This research was arranged in a Randomized Complete Block Design (RCBD), with treatment of salt concentrations at 5%, 10%, 15%, 20%, 25%, and 30% (w/w). The follow-up test used the Least Significance Difference (LSD) at 5%. The result of this study showed that the addition of 10% salt produced the best joruk with the best microbiological and chemical properties as follows: total LAB of 8.75 log cfu/g, total microbes of 13.25 log cfu/g, and total mold of 4.27 log cfu/g, pH of 5.85, total lactic acid of 2.97%, Total Volatile Base (TVB) of 153.05 mgN /100g, and water content of 59.33%. Based on this study, it is concluded that the addition of salt at different concentrations significantly affects the pH, total lactic acid, total lactic acid bacteria (LAB), and water content of joruk.

Pulau Pasaran dikenal sebagai penghasil ikan teri (Stolephorussp.) di provinsi Lampung dengan jumlah produksi mencapai 57,6 ton setiap bulannya. Hal ini menjadikan Pulau Pasaran sebagai sentra penghasil ikan di provinsi Lampung. Upaya pengolahan yang dilakukan oleh masyarakat menghasilkan berbagai bentuk produk seperti ikan teri kering, teri kemasan vakum dan produk diversifikasi untuk makanan ringan serta pengolahn limbah sebagai bahan baku pakan (feed) untuk ikan nila dan lele. Upaya pengolahan ini disamping dapat meningkatkan nilai tambah (value added) dari ikan teri juga dapat menerapkan konsep zero waste dalam proses pengolahan ikan teri, sehingga pendapatan masyarakat lebih optimal.

Kecalokis recognized as a typical shrimp sauce traditionally produced by the Malay inhabitants in Bangka Island and Palembang, Southern region of Sumatra. Comparing to terasi, the most common Indonesian fermented shrimp, the information on kecalokhas rarely been reported. This study aimed to obtain the characteristics of both the geographical origin of kecalokproduct from Bangka and Palembang. A descriptive analysis was used to observe the profiles of both kecalokproducts including sensory, microbiology, proximate, and physical analysis. Results showed that kecalokfrom both locations had similar characteristics, i.e. a distinctive taste and aroma, high nutrition value, and containing some useful bacteria (LAB) which have beneficial role in human body. Therefore, kecalokwill be a prospective functional based-indigenous food in Indonesia.
