Setiap buku ajar yang disebarluaskan secara bebas perlu dilakukan sebuah penilaian untuk mengetahui kelayakannya, terutama dalam pembelajaran bahasa kedua. Penelitian ini bertujuan untuk mendeskripsikan dan menjelaskan kelayakan isi dan muatan budaya buku ajar BIPA “Sahabatku Indonesia” tingkat BIPA 1 edisi tahun 2019 yang disusun oleh Badan Pengembangan Bahasa dan Perbukuan Kemendikbud. Penelitian berfokus pada kelayakan isi dan muatan budaya. Penelitian ini menggunakan metode kualitatif dengan konten analisis. Instrumen yang digunakan berupa lembar analisis dari teori penilaian kelayakan buku ajar berdasarkan Muchlis. Berdasarkan hasil penelitian, dapat disimpulkan bahwa buku ajar Sahabatku Indonesia tingkat BIPA 1 “cukup layak” digunakan, dengan persentase kelayakan sebesar 65,8%. Sebagian besar kekurangan buku ajar Sahabatku Indonesia tingkat BIPA 1 disebabkan oleh kurangnya pranala dan rujukan serta ketidaksesuaian materi dan kosakata dengan target pembelajaran dan elemen kompetensi tingkat BIPA 1.

“…[1] The permeability characteristics of hydrate reservoirs were the decisive factors for gas production. Current experimental studies were mainly focus on artificial sediments, [2][3][4] and the numerical simulations for gas production were also based on relative high permeability. [5] The effective permeability of natural sediment cores was measured to be 1-100 mD in the Eastern Nankai Trough, which was 2-3 orders of magnitude less than conventional estimates.…”

“…As the filtration process proceeds, solid particles in suspension continuously deposit on the surface of medium to form a filter cake or block inside pores of medium. Then, flow resistance increases, and filtration rate decreases rapidly. , Permeability is a key parameter for studying the filtration process, and it is the most basic problem in studying seepage of porous cake materials . However, the permeability in both the Ruth equation and Kozeny–Carmen (K–C) equation is treated as a constant.…”

Permeability plays a decisive role in the dewatering process and reflects the difficulty of filtration, especially for soft solid material such as sludge. In this paper, the physicochemical properties and dewatering performance of sludge conditioned with different kinds of flocculants were investigated. Results showed that the flocculant could change the sludge microstructure such as floc morphology, specific surface area, and fractal dimension. Compared with filtration pressure, flocculants had a greater influence on sludge permeability which was a significant negative correlation with filtration pressure and was a positive correlation with flocculant dosage. In order to describe the fact that fluid flows through the porous voids for soft solid sludge, the improved Kozeny constant was corrected. Research showed that permeability was more significant in the dewatering process for the sludge conditioned with inorganic flocculants than that with organic flocculants. The Kozeny constant was not only relevant with suspension nature but also with filtration pressure. The range of the improved Kozeny constant was reasonably determined based on flocculant type, concentration, and filtration pressure, which was of great help to project applications. For raw sludge, the improved Kozeny constant was 958 times than that of the original value, and it decreased significantly for conditioned sludge.
