Penelitian ini dilatarbelakangi metode pembelajaran guru DPK Keramik menempatkan peranan guru lebih dominan dibandingkan siswa. Dekorasi keramik yang dibuat, mengolah keramik sebagai fungsi pakai. Bentuk penelitian adalah deskriptif yang bersifat kualitatif. Bertujuan untuk mendeskripsikan tujuan penelitian pertama sampai dengan ketiga, yaitu (1) menerapkan metode pembelajaran dekorasi keramik teknik marble di SMK Negeri 1 Sukasada, (2) mendeskripsikan keunggulan dan kelemahan metode pembelajaran dekorasi keramik teknik marble di SMK Negeri 1 Sukasada, (3) mendeskripsikan hasil penerapan dekorasi keramik teknik marble di SMK Negeri 1 Sukasada. Penelitian ini menggunakan teknik pengumpulan data observasi, wawancara, dan dokumentasi dengan objek penelitian adalah guru dan siswa di jurusan DPK Keramik kelas XI. Hasil penelitian ini adalah (1) data berupa dokumentasi dan deskripsi proses guru dalam menerapkan metode pembelajaran dekorasi keramik teknik marble, yaitu dengan metode yang berpusat pada guru (ceramah dan demonstrasi) yang selanjutnya metode yang dipusatkan kepada siswa (eksperimen, mengajar sesama teman, metode drill dan elaborasi). (2) dari proses guru menerapkan metode maka didapat keunggulan dan kelemahan metode pembelajaran dekorasi keramik teknik marble, metode dengan keunggulan paling banyak adalah eksperimen yaitu 8 keunggulan dan metode dengan kelemahan terbanyak adalah metode ceramah dengan 6 kelemahan. (3) hasil penerapan metode pembelajaran dekorasi keramik teknik marble berupa benda keramik yang sudah diberikan dekorasi marble, karya siswa dengan metode drill dan eksperimen yang diberikan guru, sudah menunjukkan keberhasilan penerapan dekorasi teknik marble. Kata Kunci : Kata- kata kunci: metode pembelajaran, dekorasi keramik, teknik marble This research is based on learning method of teacher of DPK Ceramic put role of teacher more dominant than student. Ceramic decorations are made, ceramic processing as a function of wear. The form of research is descriptive that is qualitative. Aiming to describe the purpose of the first study to the third, namely (1) applying the marble ceramic decoration learning method in SMK Negeri 1 Sukasada, (2) describing the advantages and disadvantages of marble ceramic decoration learning method at SMK Negeri 1 Sukasada, (3 ) describes the result of application of ceramic decoration of marble technique at SMK Negeri 1 Sukasada. This study uses observation data collection techniques, interviews, and documentation with the object of research are teachers and students in the department of Class XI Ceramics. The results of this research are (1) data in the form of documentation and description of teacher process in applying marble ceramic decoration teaching method, that is with teacher-centered method (lecture and demonstration), then the method which is centered to the students (experiment, drill and elaboration). (2) from the process of applying the method teacher then obtained the advantages and disadvantages of marble ceramic decoration learning method, the method with the most advantage is the experiment that is 8 advantages and the method with the most weakness is the lecture method with 6 weaknesses. (3) result of application of marble decoration technique method of marble ceramic that have been given marble decoration, student work with drill method and experiment given by teacher, has shown success of marble technique application implementation. keyword : Keywords: learning method, ceramic decoration, marble technique

Dummy Decal: Contemporary Ceramics and Endless Decorative Creative Work

Regardless of the type of product or the differences in its basic elements, the product graphic is synonymous with high beauty, uniqueness, and precision. It is parallel with the beautiful ornaments that adorn the surface of the ceramic product, which originate from diverse civilizations and reflect the maker's creative inspiration. The decal is based on the most advanced and widely used ceramic decoration techniques in Europe and China, which serves as an inspiration for the rest of the globe when it comes to putting decoration to their products. Whichever is the case, the manufacturing and distribution expenses of decal decoration techniques are considerable, needing extensive preparation and execution to provide a high-quality result. As a result, the invention of the 'Dummy Decal' decoration process has enabled manufacturers of ceramic products to maintain a consistent level of output while adding differentiation to their designs. Water Based Inkjet Water Transfer Paper is a fresh source of inspiration for creative items and ceramic works. With a modest access fee and the ability to purchase, this decoration serves as a magnet for contemporary products and creative works. This article can be used as a guide and resource for small and medium-sized businesses, as well as individuals, to assist them in developing their creative thinking when it comes to marketing their organic products.

Ionic Liquid-Assisted Synthesis of C@ZrSiO4 Ceramic Inclusion Pigment

An innovative two-step route was successfully applied to the ionic liquid-assisted synthesis of C@ZrSiO4 ceramic pigments, which is able to reduce the reflux time from many hours to a few minutes. The structure and morphology of the inclusion pigments were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). And the chromatic value of the pigments was measured by the CIE color system. The results show that the pigment in the absence of ionic liquid (IL) exhibited homogeneous single t-ZrO2 phase, while the samples in the presence of IL showed coexistence of two crystal phases (m-ZrO2 and ZrSiO4). The CIE coordination L* value decreased with the increase of TEOS amounts due to the pure zircon formation. The as-prepared pigment showed high tinting ability, as L*=37.16, a*=0.71, b*=0.3, making it promising candidate for ceramic decoration.

A Novel Cyanide-Free Gold Complex: [Au(tu)2 ]SCN H2O

A novel aurous complex containing thiourea and thiocyanate as the mixed ligands is synthesized by the ISRC method in this paper. Its formula is determined as [Au (tu)2 ]SCN H2O by elemental analysis. The electrochemistry studies show it is a typical ionic compound and its conductivity reaches 13×10-4 Sm2mol-1. TG studies and related stability tests reveal the compound is excellently stable. By using single factors experiments the optimal plating index has been gotten and they are: pH=1.5~3.5, [A =1.5~2.5 g/L, temperature 30~50°C and plating time 10 minutes respectively. It is a competitive gold complex and will be find a wide application in electroplating, chemical deposition, ceramic decoration and other related areas.
