"Teknik rekayasa jaringan digunakan untuk memperbaiki jaringan rusak dengan menggunakan pengganti biologis. Saat ini,para peneliti mengembangkan implan untuk rekayasa jaringan. Material berbasis polimer sebagai bahan implan banyak menarik perhatian karena biaya realtif murah, sumber berlimbah dan dapat diterima tubuh. Pendekatan material rekayasa jaringan tulang didasari dengan substansi dari material penyusun tulang. Pada penelitian ini digunakan hidroksiapatit yang berfungsi sebagai filler karena mampu memberikan kekerasan yang baik dan meningkatkan kemampuan adhesi (perekatan) sel. Silk Fibroin berfungsi sebagai matriks yang berfungsi untuk meningkatkan elastisitas dan sifat mekanik komposit. Hidroksiapatit berhasil ditumbuhkan pada silk fibroin dengan metode in-situ berbantukan iradiasi gelombang mikro (720 W; 15 menit). Larutan SF yang telah diekstraksi dengan Adjisawa reagent dicampurkan dengan larutan kalsium fosfat yang telah dipreparasi menggunakan Ca(OH)2 dan (NH4)2HPO4 sebagai prekursor. Pengaruh rasio SF terhadap kekerasan komposit HA/SF diamati pada variasi rasio (v/v) yaitu HA90/SF10, HA80/SF20, dan HA70/SF30. Hasil XRD didapatkan bahwa ukuran kristal (L) dan indeks kristalinitas (CI) menurun seiring bertambahnya rasio SF pada komposit. Indeks kristalinitas terbesar terhitung pada sampel HA90/SF10 yaitu 32,6 dan 0.885. FTIR dipilih pada sampel HA70/SF30 didapatkan gugus fungsional utama yaitu pada bilangan gelombang 569, 608, 900, dan 1036, amida I pada bilangan gelombang 1636, amida II pada bilangan gelombang 1527 dan amida III pada bilangan gelombang 1264 yang menandakan bahwa HA dan SF saling mengikat menggambarkan bahwa kandungan SF mempengaruhi ukuran partikel, dimana semakin banyak kandungan SF maka semakin menurun ukuran partikel yang terbentuk. Hasil uji mekanik microvickers menunjukkan bahwa semakin banyak rasio SF dalam komposit HA/SF mengakibatkan semakin tinggi nilai kekerasan komposit ditandai dengan nilai kekerasan sampel HA70/SF30 yaitu 0,0335 GPa, sampel HA80/SF20 sebesar 0,0278 GPa dan sampel HA90/SF10 sebesar 0,0266.
Tissue engineering techniques are used to repair damaged tissue using biological substitutes. Currently, researchers are developing implants for tissue engineering. Polymer-based materials as implant materials have attracted a lot of attention because of their relatively low cost, wasteful sources and acceptable to the body. The bone tissue engineering material approach is based on the substance of the bone building material. In this study, hydroxyapatite was used as a filler because it was able to provide good hardness and increase cell adhesion. Silk Fibroin serves as a matrix that serves to increase the elasticity and mechanical properties of the composite. Hydroxyapatite was successfully grown on silk fibroin by in-situ method assisted by microwave irradiation (720 W; 15 minutes). The SF solution that had been extracted with Adjisawa reagent was mixed with a calcium phosphate solution that had been prepared using Ca(OH) 2 and (NH4)2HPO4 as a precursor. The effect of the SF ratio on the hardness of the HA/SF composite was observed in the variation of the ratio (v/v) namely HA90/SF10, HA80/SF20, and HA70/SF30. XRD results showed that the crystal size (L) and crystallinity index (CI) decreased with increasing SF ratio in the composite. The largest crystallinity index was calculated for the HA90/SF10 sample, namely 32.6 and 0.885. FTIR was chosen on the HA70/SF30 and the main functional groups were found at wave numbers 569, 608, 900, and 1036 ,amide I at wave number 1636 ,amide iI at wave number 1527 and amide III at wave number 1264 which indicates that HA and SF bind to each other. The SEM results show that SF content affects particle size, where the more SF content, the particle size was decrease. The results of the microvickers mechanical test showed that the higher the ratio of SF in the HA/SF composite, the higher the hardness value of the composite was indicated by the hardness value of the HA70/SF30 sample, which was 0.0335 GPa, the HA80/SF20 sample of 0.0278 GPa and the HA90/SF10 sample of 0.0278 GPa. 0.0266.

ABSTRAKInisiatif Silk Road Economic Belt SREB dari China menimbulkan baik entusiasme maupun keresahan di seluruh penjuru dunia. Pembangunan dari SREB akan memudahkan aliran ekonomi antara Eropa dengan Asia yang kemudian meningkatkan kerjasama dan kemakmuran di kawasan tersebut. Namun motif asli dibalik pengembangan SREB masih menjadi pertanyaan besar. Uni Eropa hingga saat ini belum memberikan respons resmi terhadap inisiatif tersebut, sementara Jerman telah menunjukkan dukungan mereka atas hal tersebut. Studi ini menganalisa motivasi dari Jerman untuk mendukung SREB melalui Teori International Political Economy. Variabel Pursuit of Wealth digunakan untuk menganalisa manfaat ekonomi yang didapat oleh Jerman dari pengembangan SREB, dan variable Pursuit of Power digunakan untuk menjelaskan kepentingan politik antara Jerman, SREB, dan juga Uni Eropa. Hasil penelitian ini menunjukkan bahwa Jerman tengah berusaha menggunakan SREB sebagai alatnya untuk merealisasikan kepentingan ekonomi dan politiknya di Uni Eropa.
ABSTRACTChina rsquo s Silk Road Economic Belt SREB initiative is raising both concerns and excitement around the globe. The development of the SREB will increase the flow of economy between Europe and Asia and in turn is supposed to raise cooperation and prosperity amongst the region. However the true motive of SREB either it be politics or economics, remains a big question. The European Union have not made an official stance towards the initiative, however Germany have shown indications of their support. This study analyzes the motivation of German in doing so through the International Political Economy Theory. The Pursuit of Wealth variable is used to analyze the economic benefits Germany may receive from the SREB, while the Pursuit of Power variable is used in attempts to understand the politics involving Germany, SREB and the European Union. The results shows that Germany is trying to utilize the SREB as a vehicle in pursuing its economic and political interest in the European Union. "

"When novelist Owen Quine goes missing, his wife calls in private detective Cormoran Strike. At first, Mrs. Quine just thinks her husband has gone off by himself for a few days--as he has done before--and she wants Strike to find him and bring him home. But as Strike investigates, it becomes clear that there is more to Quine's disappearance than his wife realizes. The novelist has just completed a manuscript featuring poisonous pen-portraits of almost everyone he knows. If the novel were to be published, it would ruin lives--meaning that there are a lot of people who might want him silenced. When Quine is found brutally murdered under bizarre circumstances, it becomes a race against time to understand the motivation of a ruthless killer, a killer unlike any Strike has encountered before"
