Abstract

Formalin merupakan salah satu senyawa kimia yang sering ditambahkan kepada ikan dan seafood. Padasaat paparan formalin masuk ke dalam tubuh manusia, maka hal tersebut sangat berbahaya bagi kesehatan manusia. Tujuan dari penelitian ini adalah untuk mendeteksi kandungan formalin pada sampel ikan dan seafood yang berasal dari beberapa pasar lokal di kota Samarinda. Metode penelitian ini bersifat deskriptif observational terhadap 149 sampel uji ikan dan seafood asin. Deteksi kandungan formalin pada ikan dan seafood dilakukan dengan rapid test kit. Pada saat sampel uji mengalami perubahan warna menjadi merah dan ungu, maka sampel tersebut terindikasi positif mengandung formalin. Ditemukan bahwa dari 10 dari 13 sampel ikan dan 4 dari 4 sampel seafood positif mengandung formalin. Jenis ikan dan seafood yang mengandung formalin di penelitian ini adalah layang, sarden, teri, baronang, pedak, haruan laut, kepala batu, kaca-kaca, tenggiri, hiu cucut, cumi, udang ebi, udang papay dan baby cumi. Penelitian ini menyarankan bahwa konsumen harus lebih berhati-hati untuk membeli ikan dan seafood yang mengandung formalin.

Abstract

Prangat Baru Village is located in a hilly area, with rainfall of 194.5 and an altitude of 150 meters above sea level. The majority of the community work as garden farmers. Farmers are encouraged to innovate in search of other plantation crop commodities, namely the cultivation of liberika coffee plants by naturally fermenting coffee beans by civets. The main objective of this program is to increase the economic level of the members of the Kopi Luwak Village farmer group through 3 (three) basic foundations, namely (1) liberika coffee cultivation, (2) civet care which pays attention to animal welfare, and (3) edutour of Kampung Kopi Luwak with various educational tourism activities. Through deliberations on the preparation of the 2021 Renja with the management of Pertamina Hulu East Borneo, it was agreed upon the activities of the Kapak Prabu 2021. Among them are a comparative study of coffee cultivation in Pangalengan Malabar, West Java, assistance for PIRT powder & coffee beans with more marketable packaging, procurement and development of liberika coffee seeds, as well as the addition of cages and pandanus civet. Based on the results of the implementation of assistance in the kapak prabu social innovation program, the basic problems of the Prangat Baru Village community were resolved and the need for social innovation had been properly achieved.

Abstract

Heavy metals are compounds that can affect the quality of a waters. Various kinds and types of heavy metals that enter and settle in sediments can cause diversity to decrease to the extinction of organisms in the waters. This study was aimed to determine the content of Cd, Pb, and Cu accumulated in water, substrate, and gastropods obtained from Kersik Village, Kutai Kartanegara Regency, East Kalimantan. Samples of water, substrate, and gastropods were collected from 4 stations with 3 repetitions. Water samples, substrates, and gastropods were analyzed using AAS. Concentration ranges of Cd, Pb, and Cu in water were 0.003 - 0.011 mg/L; 0.161 - 0.731 mg/L; and 0.007 - 0.009 mg/L, respectively. The concentration ranges of Cd, Pb, and Cu on the substrate were 0.021 - 0.182 mg/kg; 19.5 - 31.12 mg/kg; and 14.29 - 15.47 mg/kg, respectively. In gastropods, the range of Cd concentrations was 0.509 - 0.675 mg/kg, while for Pb and Cu were 15.96 - 21.52 mg/kg and 57.78 - 92.4 mg/kg, respectively. The concentration of Pb in gastropods at all stations has exceeded the quality standard based on SNI-7387-2009, while the concentration of Cu in gastropods at all stations has also exceeded the quality standard based on BPOM No.03725/B/SK/89. Bioconcentration Factor (BCF) of organisms to sediment (BCFo-s), shows the ability to accumulate Cu in Gastropods which is higher than Cd and Pb. Bioconcentration Factor (BCF) analysis of organisms to water (BCFo-w), showed that the accumulation of Cd, Pb, and Cu were in the low, medium, to high categories. The average comparison of concentrations of the three heavy metals at each observation station was not significantly different (sig. > 0.05).

Abstract

Formalin is a chemical compound that is often added to fish and seafood. When formalin exposure enters the human body, it is very dangerous for human health. The purpose of this study was to detect the formalin content in fish and seafood samples from several local markets in the city of Samarinda. The research method was descriptive observational on 149 test samples of fish and seafood salted. Detection of formalin content in fish and seafood was detected by the rapid test kit. When the test sample changed to red and purple color, the sample was indicated to be positive for formalin. It was found that 10 out of 13 fish samples and 4 out of 4 seafood samples were positive for formaldehyde. The types of fish and seafood containing formalin in this study were layang, sarden, teri, baronang, pedak, haruan laut, kepala batu, kaca-kaca, tenggiri, hiu, cumi, udang ebi, udang papay and baby cumi. This study suggests that consumers should be more careful to buy fish and seafood that contain formaldehyde.
