Tendürek Sönmüş Yanardağının Florotoksik Kaynak Suları Örneğinde Doğal Florozisin Çiftlik Hayvanı Kemiklerinin Flor Düzeyleri Üzerine Etkisi

It is known that the level of Fluoride in the spring waters from some volcanic lands is high and these waters cause Fluoride toxicity. Scientific studies have shown that in Doğubayazıt there is high amount of fluoride in some spring waters originating from the foothills of Tendürek volcano and normal level in Iğdır and Cappadocia volcanic lands. In this study, it was revealed comparatively how the spring waters in these regions affect the bone Fluoride levels of farm animals that are given as drinking water. Fluoride analyses in bone, water and urine samples were performed by means of an ion meter equipped with an iron selective electrode (ISE). The urine and bone fluoride levels of farm animals followed a similar course to water samples. Fluoride levels in bone and urine samples of Doğubayazıt were detected to be significantly higher in compared to Igdır and Cappadocia regions. Bone Fluoride analysis results were also supported by external bone and dental examination findings. The presence of a strong relationship between the analysed water, urine and bone Fluoride levels was determined in this study. It was found that drinking water has a very strong effect on urine and bone in terms of fluoride level. Consequently, Fluorine levels in the bones of farm animals drinking water with high Fluorine levels originating from Tendürek Mountain in Doğubayazıt were found to be higher than normal. Fluoride levels in the bones of farm animals that drank high-fluoride waters originating from Tendurek mountain in Doğubayazıt were found to be higher than normal. This situation can be evaluated as evidence that natural Fluoride toxicity formed by drinking water causes Fluoride accumulation on bones.

Pemanfaatan tulang ikan kambing-kambing (Abalistes stellaris) sebagai sumber kalsium pada produk tepung tulang ikan

Tulang ikan kambing-kambing salah satu limbah padat yang masih menjadi hasil samping yang belum dimanfaatkan. Tulang ikan kambing-kambing merupakan salah satu limbah padat yang sangat berpotensi sebagai salah satu sumber kalsium. Penelitian ini bertujuan untuk memanfaatkan tulang ikan kambing-kambing menjadi produk yang bernilai ekonomis dan sumber kalsium. Penelitian ini menggunakan metode hidrolisis protein untuk mengetahui karakteristik bahan baku tulang ikan kambing-kambing dan proksimat (kadar air, kadar lemak, kadar abu), kalsium dan nilai FTIR tepung tulang ikan kambing-kambing yang dihasilkan. Penelitian ini menggunakan ekstraksi basa NaOH dengan perbedaan konsentrasi yaitu 1N, 1,5N dan 2N. Nilai rendemen yang didapatkan adalah 7,55%, 12,94% dan 10,96%. Nilai kadar air yang didapatkan adalah 3,79%, 4,15% dan 3,87%. Nilai kadar lemak adalah 0,12%, 0,11% dan 0,10%. Nilai kadar abu yang didapatkan adalah 90,05 %, 88,76% dan 87,52%. Nilai kalsium yang didapatkan adalah 31,83 %, 35,75% dan 32,33%. Pengujian FTIR menunjukkan pada tepung tulang ikan kambing-kambing terdapat kalsium.Kata kunci: ekstraksi; kalsium; ikan kambing-kambing (Abalistes stellaris) Starry triggerfish bone is one of the solid waste, which is a by-product that has not been utilized. It has great potential as a source of calcium. This research aims to utilize starry triggerfish bone to be a valuable product and source of calcium. This research used the protein hydrolysis method to determine the characteristic of raw material and proximate of starry triggerfish bone (water, fat and ash content), calcium and FTIR values of starry triggerfish bone meal. This research uses NaOH base extraction with different concentrations of 1N, 5N and 2N. The yield value obtained were 7,55%, 12,4% and 10,96%. The values of water content obtained were 3,7%, 4,15% and 3,87%. The value of fat content were 0,12%, 0,11% and 0,10%. Ash content values obtained were 90,05%, 88,76% and 87,52%. Calcium values obtained were 31,83%, 35,75% and 32,33%. FTIR testing showed that the bone meal of starry triggerfish contained calcium.Keywords: extraction; calcium; starry triggerfish (Abalistes stellaris)

Produksi Tepung Tulang Ikan Tuna (Thunnus Sp) Dengan Metode Kering Sebagai Sumber Kalsium Dan Fosfor Untuk Pembuatan Biskuit

Research has been conducted on processing tuna bones into flour which has a high mineral content which aims to produce nutritious biscuits in the form of food products. This study obtained the results that the tuna bone water content was 6.40% and the biscuit water content was 2.67%, the calcium and phosphorus content of tuna fish was 5.35% and 3.37%, while the biscuit dough with variations in the ratio between flour and fish bones namely 100 : 0; 95 : 5; 90 : 10; and 85 : 15 obtained the results of increased calcium content of 0.9%; 0.97%; 1.25%; and 1.29%; and phosphorus content 0.38%; 0.43%; 0.46%; and 0.60%; and the protein content is 9.32%; 11.74%; 11.99%; and 12.4

Near infrared spectroscopic assessment of loosely and tightly bound cortical bone water

NIR spectroscopy can differentiate water loosely bound to bone tissue, and tightly bound to either collagen or mineral.
