Hasil-hasil penelitian glasir Balai Besar Keramik akan dikaji dalam kaitannya dengan permasalahan di industri keramik di Indonesia. Kajian ini bertujuan mengevaluasi perkembangan penelitian glasir di Balai Besar Keramik (BBK) dalam keterkaitannya dengan topik yang diangkat dan permasalahan di industri keramik Indonesia. Perkembangan penelitian akan dikaji dalam rentang waktu 5 tahunan sesuai topiknya. Isu-isu industri juga diklasifikasikan kedalam 5 topik isu, yakni: bahan baku, teknologi proses, mutu produk, inovasi produk, dan lingkungan. Sampel data diambil dari penelitian-penelitian glasir mulai tahun 1992 hingga 2016 berdasarkan KTI Nasional dalam majalah JKGI dan ITKG. Sedangkan informasi tingkat permasalahan industri keramik didekati dari jajak pendapat 20 asesor industri keramik. Metode penelitian yang digunakan adalah metode statistik deskriptif dan inferensial ANOVA dengan tingkat kepercayaan 95%. Hasil perhitungan ANOVA memberikan nilai p-value dibawah 0,05 dan perhitungan nilai F 4,75 (diatas kriteria F 2,87) yang menunjukkan bahwa penelitian-penelitian glasir selama ini memiliki hubungan yang signifikan dengan permasalahan di industri keramik Indonesia. Walaupun demikian, dalam kaitannya dengan industri keramik yang lebih besar, beberapa hal perlu ditingkatkan dalam penelitian bahan baku dan teknologi proses yang juga dibahas dalam kajian ini.

The density and magnetic properties of barium ferrite from BaFe12O19 Nanoparticles prepared by microemulsion method have been studied by comparing with the properties of micro-scaled BaFe12O19 prepared by metallurgical method. The preceding preparation consists of emulsification process, mixing, aging, centrifuging/separation, drying, grinding, and calcination at temperature of 900 oC, which brings on the BaFe12O19 nanoparticles powder as its final product. Then, the obtained powders have been formed at compaction pressure of 200 Kg/cm2 and sintered at temperature of 1100 oC. The indications of formed BaFe12O19 nanoparticles have been confirmed via XRD and TEM testings which their dimension sizes are under 100 nm. Based on density measurements, the density of barium ferrite prepared by microemulsion method is higher than that of by metalurgical method (i.e. 5,3 gr/ml). While, the permagraph examinations have indicated that both remanence magnetic induction (2.49 kOe) and maximum energy product values (0.47 MGOe) of barium ferrite prepared by microemulsion method are higher about 1.22 and 1.47 times, respectively.

Industrialization of lithium batteries in Indonesia requires in addition to mineral technology as well as local raw material support. Solid electrolytes are one of the lithium battery cell components that determine the working stability (long life-time) of the battery and the safety of its use. In this study solid electrolyte for secondary battery with type of Lithium Aluminum Titanium Phosphate (LATP) was synthesized in variation of LATP.n% Li2O where Li2O functioned as conductivity enhancing additive with n=0,5,10. Theoretically, the largest LATP solid electrolyte content is the Titanium Phosphate (TiP) material about 80% by weight fraction, the material can be obtained from natural mineral materials such as ilmenite and apatite in Indonesia. It has qualified for the industrialization of battery components with domestic component level (TKDN) material exceeding 60%. The TiP material was prepared by sintering destruction and acid-base methods, while the LATP.n% Li2O was made using powder metallurgy and sintering method with pre-heating 400 ° C. The XRD test result shows a diffraction pattern of TiP similar to TiP pattern from other publication reference. A slight difference in the XRD pattern indicated an excess of TiO2 rutile content in TiP material and other impurities, which has also been proven by XRF test results. The SEM test result provided a micrograph showing off the crystal blocks corresponding to the shape described by other references. The LATP material made has a single and stable ionic conductivity mechanism based on the interpretation of the Cole-cole plot diagram. The result of ionic conductivity test for LATP.n% Li2O showed variation with n = 5 having conductivity (4.5x10-5 S / cm) higher than other variations.

Magnet barium ferit merupakan salah satu jenis magnet permanen yang masih mempunyai potensi untuk dikembangkan, salah satunya dengan pemberian doping untuk mempengaruhi sifat magnetiknya. Dalam penelitian ini, telah dilakukan penambahan doping MnO dan MnO2 pada barium ferit. Metode pembuatan barium ferit yang dilakukan adalah dengan metode metalurgi serbuk dan diberikan penambahan doping MnO dan MnO2dengan variasi %berat. Hasil yang diperoleh yaitu sampel dengan doping MnO2mempunyai karakteristik sifat magnetic yang lebih tinggi jika dibandingkan dengan doping MnO. Nilai doping MnO2 terbaik pada komposisi 1,5% dengan nilai Br 1,91kG, Hcj 3,073 kOe dan BHmax 0,76 MGOe. Dari penelitian ini, dapat disimpulkan doping MnO2relatif lebih baik digunakan untuk meningkatkan sifat magnetik magnet barium ferit.

Telah dilaksanakan studi tentang pengaruh ukuran butiran NdFeB pada sifat densitas dan kemagnetan bahan magnet komposit hybrid BaO.6(Fe2O3)/NdFeB. Kegiatan penelitian ini meliputi: proses sintesis bahan magnet komposit dalam matrik PVA, pengujian densitas bulk dan karakterisasi kurva hysteresis magnetisasi serta analisis hasil pengolahan data penelitian. Perbandingan komposisi massa BaO.6(Fe2O3):NdFeB ditentukan 1:1. Adapun variasi penelitian diambil dari ukuran butiran NdFeB yang diperoleh berdasarkan standar mesh ayakan 60 (mewakili ukuran 250µm), 230 (63µm), 325 (44µm) dan 400 (37µm) yang mana ukuran butiran BaFe dibuat tetap pada mesh ayakan 325 (44µm). Keempat sampel variasi ini diberi label mesh 60, mesh 230, mesh 325, dan mesh 400. Hasil pengujian densitas bulk menunjukkan kepadatan terbaik untuk sampel mesh 60, hasil ini diikuti secara kuadratik oleh remanensi magnetiknya. Pengamatan parameter kuat medan maksimum dalam kurva histeresis magnetisasi mengindikasikan estimasi temperatur Curie yang paling baik/tinggi untuk sampel mesh 60. Hasil pengujian nilai induksi remanen (Br) dan perhitungan total energi produk maksimum (BHmax) menguatkan bukti hipotesis bahwa sampel mesh 60 (ukuran butiran terbesar) memiliki sifat kemagnetan yang lebih baik dari sampel lainnya.

The addition of MnO2 in synthesis of barium ferrite magnet were prepared by powder metallurgy method with variation formula of MnO2 0%, 0.1%, 0.2%, 0.3%, 0.5% and 1% sintered at 1175 ºC. Material characterization includes X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) and permagraph were employed to investigate the effect of MnO2 addition to magnetic properties and sample density. Hysteresis curve using permagraph showed that the addition of MnO2 have an effect on the increasing of magnetic properties and density. Remanence induction (Br), coercivity (Hc) and density (ρ) reached the maximum value of 1.36 kG, 2.757 kOe and 4.29 g/cm3 respectively on different formula MnO2. The best value of MnO2 addition could be concluded on the addition MnO2 of 0.3% with Br = 1.36 kG, Hc = 2.683 kOe, and ρ = 4.29 g/cm3. The XRD results showed the formed of barium ferrite phase in the sintered sample at 1175ºC. While the SEM result revealed that the addition of MnO2 affected the density of barium ferrite particles.
