Protein is the most important nutrients in the body, which serves as a new network-forming and maintaining or repairing worn tissue. Protein cucumbers reach 82% of his body. However, the protein can undergo denaturation when heated. Formulation of the research problem is whether there was an effect on long boiling sea cucumbers (Holothuria argus) the protein content. The research objective was to determine whether there is a long effect on the boiling sea cucumbers (Holothuria argus) the protein content. This type of research is experimental. The study population was all kinds of sea cucumbers are caught by fishermen in Kel.Sukolilo Kec.Bulak Surabaya. The research sample is sea cucumber Holothuria argus species caught by fishermen in Kel.Sukolilo Kec.Bulak Surabaya. Research using the 5 treatments with 5 repetitions. Criteria longer boiling is P1 (0 min / control), P2 (15 min
Makanan dan minuman yang dikemas dalam kaleng memiliki kemungkinan untuk terkontaminasi logam berat yang berasal dari komponen penyusun kaleng. Kontaminasi logam berat bisa menyebabkan keracunan dan berbahaya bila masuk ke dalam system metabolism tubuh dengan jumlah yang melebihi batas yang telah ditetapkan dalam SNI dan BPOM. Penelitian ini bertujuan untuk menganalisa Timbal (Pb), Kadmium (Cd) dan seng (Zn) pada sarden, kornet, susu kaleng, sari buah, minuman berkarbonasi. pengambilan sampel dilakukan di dua lokasi berbeda yaitu pasar modern dan pasar tradisional, dengan tujuan agar dapat membandingkan perbedaan pada pasar modern dan pada pasar tradisional.Serapan logam diukur dengan menggunakan spektofotometri serapan atom (SSA) pada gelombang yang spesifik. Hasil penelitian adalah kadar cadmium (Cd) tidak teridentifikasi, kadar logam Timbal (Pb) pada sampel makanan dan minuman kaleng adalah 0.01 mg/kg, 0.018 mg/kg, 0.026 mg/kg, 0.012 mg/kg, 0.027 mg/kg, 0.027 mg/kg, 0.018 mg/kg, 0.015 mg/kg, 0.024 mg/kg dan 0.019 mg/kg, sementara itu cemaran Zn adalah 0.188 mg/kg, 0.169 mg/kg, 0.193 mg/kg, 0.184 mg/kg, 0.129 mg/kg, 0.105 mg/kg, 0.107 mg/kg, 0.098 mg/kg, 0.176 mg/kg, 0.152 mg/kg. Semua sampel makanan dan minuman kaleng tidak ada yang melebihi batas maksimum cemaran yang telah di tetap kan dalam SNI dan Badan Pengawas Obat dan Makanan. Kadar cemaran logam berat Pb dan Zn pada sampel makanan dan minuman kaleng dari pasar tradisional lebih tinggi daripada sampel makanan dan minuman kaleng dari pasar modern Kata kunci : Makanan-Minuman Kemasan Kaleng, SSA, Timbal, kadmium, seng
This study aims to determine the effect of Aloe vera extract in reducing formaldehyde levels in tuna processed into "pindang" after being given Aloe vera extract. This type of research is experimental. The population in this study was boiled fish sold in the Sawotratap Market. This research was conducted at the Laboratory of Chemistry at the University of Muhammadiyah. Data were analyzed using analysis of variance at a significant level α = 0.05 followed by the Duncan test. The average formaldehyde concentration before being given Aloe vera extract at a concentration of 0% is equal to 23.7 mg / L, and the lowest formalin content in boiled fish with 100% treatment is equal to 5.6 mg / L. Aloe vera extract showed a significant decrease in formaldehyde levels in boiled fish (p <0.05). It can be concluded that the administration of Aloe vera extract is effective in reducing formaldehyde levels.
Tanggal Submit:28 Januari 2019 Tanggal Review:30 April 2019 Tanggal Publish Online:17 Mei 2019 Potatoes are one of the vegetables that contain substances that are important for the formation of body tissues, such as protein and fat. Potatoes also form red blood cells or hemoglobin (Ca, P and Fe). In Indonesia tend to process potatoes using only meat. The skin is removed, even though the nutritional content of the skin is five times greater than the meat. Potato peels that supply querestin, antioxidants and flavonoids that act as free radical acceptors. (Free radicals are reactive molecules that cause damage to the body that can lead to diseases such as heart disease and cancer) in the skin of potatoes found also effective antioxidants, chlorogenic acid. Potato skin is also proven to increase hemoglobin levels (Khomsan, A, 2009). However, that does not mean potato skin does not have adverse side effects, if the use is not appropriate. In order to use it optimally, you need to know enough information about the advantages and disadvantages and the possibility of abuse. However, the level of toxicity from potato skin is still unknown. Brine Shrimp Lethality Test (BSLT) is one of the oxicity test methods that is widely used in tracing bioactive compounds that are toxic from natural materials. This research is an experimental research with post test-only control group design approach. Treatment with giving potato skin juice to Artemia salina Leach larvae with the aim to determine the potential of plant biological activity based on the toxicity of secondary metabolites contained in it, and at the same time as the initial screening test of anticancer activity of chemical compounds in potato skin juice. The results showed the LC50 value was at a concentration of 0.5% to 1% and based on the results of SPSS 21 analysis with probit analysis obtained LC50 price data of 0.746 gr / ml (7460 μgr / ml), based on the results of research and data analysis it can be concluded that potato skin has an LC50 value at a concentration of 0.746 gr / ml (7460 µgr / ml). With an LC50 price of more than 1000 µg / ml according to the BST method the potato skin does not have the potential for toxicity so the skin of the potato has the potential as an alternative to increasing hemoglobin levels.Keywords: potato skin, toxicity, BSlT
