“…In addition to changes in the compounds formed, physical changes are very clearly visible, namely a change in color from beige to gray-white and the hard solid form becomes more brittle. This change occurred due to the reduced water content in the pearl oyster shell samples [2]. The changes in the mass of the clam shells also occurred during the calcination process as shown in Figure 3.…”

Pearl clam shell waste can be decomposed as a result of CaO compounds. CaO is a compound that can be applied in various fields such as biomaterials, electronics, agricultural industries, and others, for example as a source of biological calcium which plays a role in the growth and survival of shrimp, lobsters, and fish. This study aims to examine the effect of Calcination Temperature on calcium oxide (CaO) characteristics of pearl clam shells (Pinctada Maxima). The procedures carried out in this study include the preparation of pearl clam shells (pinctada maxima), the formation of Calcium Oxide (CaO) using the calcination method which is then continued with the characterization of the test sample. The CaO characteristics studied include CaO characteristics such as CaO compound content, powder size, powder density, bulk density and porosity. The results of measuring the CaO characteristics of pearl clam shells with variations in calcination temperature get an increase in calcination temperature resulting in the CaO yield value tending to decrease with an increase in CaO levels. Bulk density is not particularly affected by calcination temperature, but powder density tends to increase with temperature increase, whereas, porosity and particle size have smaller values. Interestingly, the values of density and porosity are inversely proportional which is closely related to empty cavities or pores formed as a result of differences in calcination temperature.

“…It is common knowledge for geologists and agronomists who say that calcium carbonate can be converted into HAP using liquid phosphate at room temperature [21]. This study uses precipitation techniques to process the Pinctada maxima pearl shells powder into HAP powder [22], [23], [24].…”

BACKGROUND: Pinctada maxima pearl shell contains inorganic and organic materials that have a bone-like basic structure that facilitates bone remodeling. AIM: This study aimed to describe the effectiveness of Pinctada maxima pearl shells as bone graft material in the world of dentistry using an animal model. METHODS: Research uses Pinctada maxima pearl shell that was processed into hydroxyapatite Pinctada maxima (HPM) powder. Chemical and surface characteristics of HPM were performed with X-ray fluorescence (XRF), Fourier transform infra-red (FTIR), and X-ray diffraction (XRD), respectively. Thirty male guinea pigs were randomly assigned into three groups: Negative control (NC), positive control, and HPM. After 14–21 days of observation, guinea pigs were sacrificed. Bone formation was seen through immunohistochemical examination of osteoprotegerin (OPG) and bone morphogenetic protein (BMP2) expression. Data were analyzed through Shapiro wills and analysis of variance with a significance level of 5%. RESULTS: There was a high expression of OPG and BMP2 on days 14–21 in the HPM group when compared to the NC group with a significance level of 5%. CONCLUSION: HPM powder can be used as a promising bone graft material in the world of dentistry.

“…Menurut Wahyuni dan Erna (2010), cangkang kerang dapat digunakan sebagai bahan komponen elektronik, karena termasuk jenis material keramik dan memiliki sifat semikonduktor. Rahayu et al (2018) menyatakan bahwa cangkang kerang memiliki mineral dengan komposisi 98,7% Ca; 0,05% Mg; 0,9% Na; 0,02% P; dan 0,2% lainnya. Tingginya kandungan kalsium karbonat pada kulit kerang yang merupakan sumber kalsium menjadikan material ini berpotensi untuk digunakan sebagai bahan sintesis HAp.…”

Biokeramik hidroksiapatit (HAp) adalah suatu komponen kimiawi sintetik dari turunan kalsium fosfat yang banyak digunakan untuk memperbaiki kerusakan jaringan keras. Salah satu bahan alami untuk membuat hidroksiapatit adalah cangkang kerang simping (Amusium pleuronectes), hasil samping dari usaha penangkapan kerang simping. Tujuan penelitian ini untuk menghasilkan sediaan HAp dari cangkang kerang simping dan mengkarakterisasi sediaan hidroksiapatit yang dihasilkan. Tahapan yang dilakukan adalah persiapan tepung cangkang kerang, proses kalsinasi dengan perlakuan suhu (700, 800, dan 900°C) dan waktu (6; 4,5; dan 3 jam), serta sintesis HAp menggunakan amonium dihidrogen fosfat. Hasil HAp terbaik diperoleh dari perlakuan suhu kalsinasi 800°C selama 4,5 jam dengan rendemen 75,20%. Gugus fungsi CO 3 2yang muncul mengindikasikan adanya vibrasi C-O dari gugus CO 3 dan gugus hidrogen fosfat (HPO 4 2-). Difraktogram HAp yang dihasilkan mendekati standar (HAp-S) dengan intensitas tinggi pada nilai 2θ: 25,88°; 31,75°; 32,18°; 32,88°; 34,05°; 39,77°; 46,61°; dan 49,97°. HAp yang dihasilkan memiliki unsur Ca dan P masing-masing 59,09 dan 40,91% dengan rasio Ca/P sebesar 1,44 dan diameter partikel rata-rata 396,88 nm. HAp ini memiliki morfologi berbentuk aglomerat dan tidak terdapat permukaan dengan tepi runcing dan tajam sehingga relatif aman untuk diaplikasikan pada jaringan lunak manusia.
