"This book summarizes the results of years of research on the problem of strength and fracture of polymers and elastomers. It sets out the modern approach to the strength theory from the standpoint of fractals, the kinetic and thermodynamic theories as well as the meso-mechanic destruction. The dimension reduction method is applied to model the friction processes in elastomers subjected to the complex dynamic loading. Finally, it analyses a relation between the fracture mechanism and the relation phenomena, and provides new experimental data on the sealing nodes in accordance with their specific working conditions where the effect of self-sealing is observed."

"Escherichia coli merupakan bakteri yang umum digunakan sebagai parameter terkait cemaran tinja dan sanitasi. Keberadaan nitrat pada air juga menjadi salah satu indikator terkait sanitasi. Beberapa penelitian menunjukkan bahwa sanitasi dapat mempengaruhi konsentrasi TDS (Total Dissolve Solids) dalam air tanah. Adanya kandungan E .coli, nitrat, dan TDS berlebih dalam air tanah yang digunakan sebagai air minum rumah tangga dapat berdampak pada kesehatan. Penelitian ini bertujuan untuk menganalisis hubungan antara kondisi sanitasi rumah tangga dengan kualitas air minum rumah tangga bersumber air tanah berdasarkan parameter E .coli, nitrat, dan TDS. Kondisi sanitasi yang diteliti meliputi 7 aspek, yaitu sarana buang air besar, tempat pembuangan akhir tinja, jarak tempat pembuangan akhir tinja, tempat pembuangan sampah rumah tangga, jarak TPS/TPA terdekat, sarana pembuangan limbah cair rumah tangga, serta jarak sarana pembuangan limbah cair rumah tangga. Penelitian ini menggunakan data sekunder dengan metode cross sectional. Analisis dilakukan dengan uji univariat dan uji bivariat menggunakan uji chi square dengan tingkat kepercayaan 90%. Hasil penelitian menunjukkan bahwa ada hubungan signifikan antara tempat pembuangan akhir tinja dengan kandungan TDS (p=0.086), tempat pembuangan sampah dengan cemaran E. coli (p=0.054), dan jarak TPS/TPA terdekat dengan kandungan TDS (p=0.061). Disarankan bagi peneliti selanjutnya untuk menganalisis lebih lanjut mengenai keterkaitannya dengan kesehatan.

Escherichia coli is a commonly used bacteria as a parameter related to fecal contamination and sanitation. The presence of nitrate in water is also an indicator related to sanitation. Several studies show that sanitation can affect concentration of TDS (Total Dissolve Solids) in groundwater. So, the presences of E. coli, nitrate, and TDS in groundwater that used as daily needs household drinking water can affect human health. This study aims to analyze the relationship between seven household sanitation conditions and the quality of household drinking water from groundwater based on the presence of E. coli, nitrate, and TDS as the parameters. The sanitation conditions include 7 aspects, such as defecation facilities, faecal disposal sites, the distance between feces disposal sites and drinking water sources, household waste disposal sites, the distance between household and temporary storage sites (TPS)/Final Processing Sites (TPA), household waste water disposal facilities, and the distance between household waste water disposal facilities and drinking water source. This research uses secondary data with a cross sectional analysis method. The analysis was carried out with univariate test and bivariate test using chi square test with a confidence level of 90%. The research results showed that there was significant relations between faecal disposal sites and TDS (p=0.086), waste disposal sites and E. coli (p=0.054), the distance to the nearest waste disposal sites and TDS. Therefore, the suggestions for further researcher to analyze the relations with health.

"The book is mainly focused on micromachining of transparent materials which, due to the nonlinear absorption mechanism of ultrashort pulses, allows unique three-dimensional capabilities and can be exploited for the fabrication of complex microsystems with unprecedented functionalities."

"Pembangunan bendungan di daerah hulu akan berakibat terhadap perubahan keluaran debit aliran dan sedimen yang berada di bagian hilirnya. Tujuan dari penelitian ini yaitu untuk menyelidiki pengaruh berfungsinya bendungan jatigede di Kabupaten Sumedang terhadap kondisi padatan tersuspensi total PTT di perairan sekitar Muara Ci Manuk. Untuk mengidentifikasi PTT, maka digunakanlah algoritma Budhiman 2004 PTT = 8.1429 exp 23.704 band merah . Dalam penelitian ini citra yang digunakan yaitu citra Landsat 8 OLI/TIRS multi temporal selama waktu sebelum dan sesudah berfungsinya Bendungan Jatigede sekitar dari tahun 2014-2017 yang digunakan untuk mengidentifikasi besaran PTT. Selanjutnya dalam penelitian ini juga mendiskusikan variasi perubahan spasial dan temporal kaitannya dengan debit aliran dan faktor oseanografi berupa arus dan gelombang laut. Daerah studi dalam penelitian ini dibagi menjadi tiga bagian wilayah, yaitu Wilayah Muara Barat Ci Manuk, Wilayah perairan antara dua Muara Ci Manuk dan Muara Timur Ci Manuk. Analisis spasial yang digunakan dalam penelitian ini yaitu trend surface analysis. Pada saat sesudah berfungsinya Bendungan Jatigede yang sudah beroperasi kurang lebih 15 bulan luasan sebaran konsentrasi PTT >80mg/l cenderung berkurang dibagian perairan yang dekat dari pantai. Hasil yang didapat juga memperlihatkan bahwa debit aliran mempengaruhi secara signifikan persebaran perairan keruh di Muara Barat pada sebelum berfungsinya bendungan, sedangkan saat ini setelah berfungsinya bendungan tidak lagi baik di ketiga daerah penelitian.

Construction of dams in the upstream area will lead to changes in flow water and sediment output in the downstream area. The purpose of this paper is to investigate the influence of the functioning of the dam Jatigede in Sumedang District towards the condition of total suspended solids TSS in the waters sea areas around the mouth of the Ci Manuk River. To identify TSS, then the algorithm is used is the Budhiman 2004 TSS 8.1429 exp 23.704 band red. In this study, the imagery used is Landsat 8 OLI TIRS multi temporal during before and after the functioning of dam Jatigede from years 2014 to 2017. This study also discusses the changes in the spatial and temporal variations in relation to the flow rate and oceanographic factors. The research area is divided into three regions, The Western Region at Mouth Ci Manuk River, Water sea areas between two mouth of Ci Manuk River, and The Eastern Mouth of Ci Manuk River. The spatial analysis that used in this study is a trend surface analysis. After Jatigede operated which were already more than 15 months, the distributions and amounts of TSS concentration 80mg l tends to reduce, especially at section the waters areas that close to the coast. The results also show the significance affect of flow rate towards the TSS distribution in Western Region before the functioning of the dam, while after the functioning of the dam it is no longer affect the distribution of TSS in the three research areas."

"This textbook explores the theory of Cosserat continuum mechanics, and covers fundamental tools, general laws and major models, as well as applications to the mechanics of granular media. While classical continuum mechanics is based on the axiom that the stress tensor is symmetric, theories such as that expressed in the seminal work of the brothers Eugène and François Cosserat are characterized by a non-symmetric stress tensor. The use of von Mises motor mechanics is introduced, for the compact mathematical description of the mechanics and statics of Cosserat continua, as the Cosserat continuum is a manifold of oriented “rigid particles” with 3 dofs of displacement and 3 dofs of rotation, rather than a manifold of points with 3 dofs of displacement. Here, the analysis is restricted to infinitesimal particle displacements and rotations. This book is intended as a valuable supplement to standard Continuum Mechanics courses, and graduate students as well as researchers in mechanics and applied mathematics will benefit from its self-contained text, which is enriched by numerous examples and exercises.

"This textbook, now in its third edition, provides a formative introduction to the structure of matter that will serve as a sound basis for students proceeding to more complex courses, thus bridging the gap between elementary physics and topics pertaining to research activities. The focus is deliberately limited to key concepts of atoms, molecules and solids, examining the basic structural aspects without paying detailed attention to the related properties. For many topics the aim has been to start from the beginning and to guide the reader to the threshold of advanced research. This edition includes four new chapters dealing with relevant phases of solid matter (magnetic, electric and superconductive) and the related phase transitions. The book is based on a mixture of theory and solved problems that are integrated into the formal presentation of the arguments. Readers will find it invaluable in enabling them to acquire basic knowledge in the wide and wonderful field of condensed matter and to understand how phenomenological properties originate from the microscopic, quantum features of nature."
