Analysis of Thiobarbituric acid Value and Benzo(α)Pyrene of Smoked Tilapia (Oreochromis niloticus) Using Corn Cob and Coconut Shells Liquid Smokes

Corn cob and coconut shells are agriculture waste that could be found easily and it has potential to be processed as liquid smoke and can be applied to Tilapia. The aim of this research is to find the different influence of corn cob and coconut shells liquid smoke to the changing of thiobarbituric acid (TBA) value, benzo(α)pyrene, and organoleptic of the smoked tilapia during storage. The result showed that the smoked tilapia which use liquid smoke corn cob has higher organoleptic value than using coconut shells. The different of liquid smoke gives very significant effect to TBA value (P<0.01). The result on PAH of smoked tilapia using corn cob and coconut shells liquid smoke showed that there was no benzo(α)pyrene detected

The Journal of International Relations, Peace and Development Studies 8th Edition Introduction

Our 8th annual edition of The Journal of International Relations, Peace Studies & Development, presents the following papers for their unique and valuable contribution to the broader discussion. Olivier Sempiga’s The impact of geopolitical risks on price variation and political trust in France: analyzing the Ukraine-Russia conflict, provides a geopolitical analysis demonstrating the far-reaching consequences of the conflict far from the Ukraine-Russian border. Camilla Gironi’s Decolonizing Kyiv’s politics of memory: current and potential implications of Russia’s 2022 invasion of Ukraine on Ukrainian monuments and toponyms, presents an insightful examination of the conflict’s influenced Ukraine’s politics of memory, in the process to revive its national identity. Renée Stoute’s Bring On the Heat, discusses the opportunities, due to the conflict, for the European Union to accelerate its adoption of sustainable energy alternatives given its rejection of Russian oil and gas. Katherine Wallentine’s Never Enough: EU Military Spending Challenges in the Face of Open Conflict, which analyzes the EU’s military spending in light of the Ukraine-Russia conflict

ANALISA JUMLAH MIKROBA (Total Plate Count) IKAN TUNA (Thunnus sp) ASAP DAN IKAN KAMBING-KAMBING (Abalistes stellaris) ASAP MENGGUNAKAN ASAP CAIR TEMPURUNG KELAPA

Penelitian ini bertujuan untuk mengetahui jumlah mikroba ikan tuna dan ikan kambing-kambing asap menggunakan asap cair tempurung kelapa selama penyimpanan suhu ruang. Sampel dalam penelitian ini adalah ikan tuna dan ikan kambing-kambing yang telah di fillet dengan berat 50 gram. Asap cair tempurung kelapa 3% serta larutan garam 10%. Analisa data pada penelitian ini menggunakan ANOVA. Parameter penelitian adalah cemaran mikroba (Total Plate Count), dan data pendukung uji organoleptik ikan segar dan ikan asap. Hasil uji TPC ikan tuna pada hari ke-0, 2, 4 adalah 2.3x103kol/gr, 2.8x104 kol/gr, tidak dapat dihitung (TBUD). Sedangkan hasil uji TPC ikan kambing-kambing asap pada hari ke-0, 2, 4 adalah 2.7x103 kol/gr, 4.7x104 kol/gr, TBUD. Hasil uji organoleptik ikan tuna asap selama penyimpanan suhu ruang hari ke- 0, 2, 4 adalah 8,67, 7,1, dan 1,83. Sedangkan hasil uji organoleptik ikan kambing-kambing asap selama penyimpanan hari ke-0, 2, 4 adalah 8,33, 7,23 dan 1,7. Hasil penelitian menunjukkan bahwa pemberian asap cair memberikan pengaruh nyata (P < 0,05) pada jumlah mikroba ikan tuna dan ikan kambing-kambing asap

Different neutral surfactant template extraction routes for synthetic hexagonal mesoporous silicas

The co-condensation of a tetraethoxysilane molecule on a neutral n-octylamine surfactant template is a convenient synthetic methodology for mesostructured material preparations. Distinct routes of template removal were investigated. The neutral surfactant was removed by calcination, hot solvent extraction, heating at 150 degreesC, in vacuo at room temperature and at 100 degreesC, and air drying, with the products assigned as HMM, HMS, HME, HMV1, HMV2 and HM, respectively. Si-29 NMR, infrared, surface area, pore diameters and pore volume determinations were employed to characterize each sample. Elemental analysis detected the presence of amine residues of 1.8, 1.2, 0.2, 1.6 and 0.30 mmol g(-1) for HMA, HME, HMS, HMV1 and HMV2, respectively. The HMM, HMS and HMV2 samples presented a low amount of amine residues, and HMS and HMV2 have the great advantage of permitting template removal without calcination.12123823382

Functional properties from nile tilapia (Oreochromis niloticus (Linnaeus, 1758)) frame protein hydrolysis

This study was to determine the functional properties of fish protein hydrolysis produced from tilapia frame. This study used a factorial design where the first factor was different types of proteolytic enzymes (E1 = bromelain, E2 = papain) and the second factor was different hydrolysis time (T1 = 5 hours, T2 = 6 hours) and was carried out with 3 replications. The results of the analysis showed that the different types of enzymes and hydrolysis time had a significant difference on the yield, degree of hydrolysis, proximate, viscosity, and protein solubility. This product has the potential to be used as food additives that can give special function properties so further research needs to be carried out to investigate these special functional properties for health and reduce the fat content that can affect the self-life product.Keywords: Functional properties; Protein hydrolysis; Nile tilapia fram
