Abstract

The preparation of CaO from golden snail (Pomacea canaliculata) and lion snail (Babylonia spirata) through decomposition at various temperature i.e 700o, 800o, 900o and 1000oC during 3 hours has been carried out. Calcium oxide from decomposition was characterized using X-Ray diffractometer. Furthermore, the characterization was continued using FT-IR spectrophotometer and determination of surface area using BET analysis. The results showed that the optimum temperature for preparation of CaO from golden snail and lion snail at 900oC with 2q values are: 32.2° , 37.4o , 54o , 64.2o , 67.3° and 32.4°, 37.5°, 67.5 °, respectively. FT-IR spectra showed characteristic vibrations for the Ca-O in the sample golden snail and lion snail combustion products at a temperature of 900oC. Ca-O absorption of golden snail samples in the wavenumber around 362.62 cm-1 and lion snail seen in wavenumber around 384.76 cm-1 indicating the presence of Ca-O vibration of the metal oxide of preparation. Golden snail and the lion snail combustion at 900oC temperature of each sample which has a surface area of 20.495 m2/g, while the lion snail 17.308 m2/g. The pore diameter of golden snail 3.753 nm and 11.319 nm of lion snail. All CaO can be categorized as mesoporous material. Keywords: golden snail, lion snail, decomposition, CaO

Abstract

Halal products generally can be seen from the Halal Certificate and or Halal Label on the product packaging. However, halal products often are sold with products that have not been guaranteed to the Halal in one place of display such as in supermarkets or the market, so it can’t be known the halalness of the product. To know halal and thayyib products, knowledge of foodstuffs are classified as halal and thayyib is needed. The purpose of this Community Service (PKM) activity is to socialize and educate related halal and thayyib products, the ingredients used in the product manufacturing process, and the halal critical point of each ingredient and or product. This form of activity is in the form of education and socialization about halal and thayyib materials and or products that enter, circulate, and be traded in the territory of Indonesia. To see the success rate and satisfaction of participants in this PKM activity are done through pretest, posttest, and questionnaire. The result of this PKM is that the participants can understand that the products that enter, circulate, and are traded in the territory of Indonesia are syubhat, so they must be halal certified. In addition, the participants of the PKM program can know and or distinguish what ingredients or products are halal or haram, as well as which are thayyib and which are not thayyib.
