"Sintesis ZSM-5 mikropori dan hirarki telah dilakukan dengan menggunakan zeolit ??alam Bayat sebagai sumber silika dan alumina. Pada zeolit ??alam dilakukan proses aktivasi, purifikasi, dealuminasi, dan fragmentasi terlebih dahulu untuk menghilangkan pengotor yang terdapat dalam zeolit alam. Sintesis ZSM-5 dilakukan dengan menggunakan metode single template dengan menambahkan TPAOH tetrapropilamonium hidroksida merupakan substrat organik sebagai pengarah struktur mikropori. Selanjutnya, sintesis ZSM-5 hirarki menggunakan metode double templated dengan penambahan TPAOH dan PDDAM poli akrilamida-co-diallyldimethylammonium chloride sebagai pengarah struktur mesopori. Zeolit ??yang disintesis kemudian dikarakterisasi dengan berbagai metode seperti FTIR, XRD, SEM-EDX dan BET. Hasil karakterisasi XRD menunjukan bahwa ZSM-5 hasil sintesis memiliki puncak khas 2? 7-10? dan 22-25?. Hasil analisa SEM menunjukan ZSM-5 hasil sintesis berbentuk heksagonal yang merupakan ciri khas kristal ZSM-5. Rasio mol Si/Al hasil sintesis ZSM-5 mikropori dan ZSM-5 hirarki berturut-turut adalah 32,34 dan 43,53. Hasil analisa BET menunjukan ZSM-5 mikropori memiliki rerata diameter pori sebesar 2,0213 nm dan ZSM-5 hirarki memilki rerata diameter pori sebesar 2,3837. Kemudian, hasil sintesis ZSM-5 dimodifikasi menjadi H/ZSM-5 untuk menghasilkan zeolit yang lebih stabil dalam lingkungan termal atau hidrotermal. H/ZSM-5 mikropori dan hirarki diuji aktivitasnya sebagai katalis dalam reaksi perengkahan senyawa n-heksadekana sebagai senyawa model. H/ZSM-5 hirarki memiliki konversi yang paling tinggi yaitu sebesar 84,73 serta memiliki persentase yield dan selektivitas produk gasolin paling tinggi berturut-turut yaitu sebesar 83,13 dan 98,11.

Synthesis of miroporous and hierarhical ZSM 5 has been carried out using Bayat natural zeolite as silica and alumina source. Prior being used as material for synthesis, natural zeolite was subjected to the process of activation, purification, dealumination, and fragmentation to remove impurities contained in natural zeolite. The synthesis of microporous ZSM 5 was performed using a single template method by adding TPAOH tetrapropylammonium hydroxide as an organic substrate as micropore structure directing agent. Furthermore, the synthesis of hierarchical ZSM 5 uses a double template method with the addition of TPAOH and PDDAM poly acrylamide co diallyldimethylammonium chloride as mesoporous structure directing agent. The synthesized zeolite were then characterized by various methods such as FTIR, XRD, SEM EDX and BET. The XRD characterization results show that the synthesized ZSM 5 had typical peaks of 2 7 10 and 22 25 . SEM analysis results showed ZSM 5 synthesized had hexagonal shaped which is characteristic of ZSM 5 crystals. The molar ratio of Si Al of synthesized ZSM 5 micropore and ZSM 5 hierarchies were 32.34 and 43.53, respectively. The result of BET analysis showed that ZSM 5 micropore has pore diameter mean was 2.0213 nm and ZSM 5 hierarchy has pore diameter mean was 2,3837. Then, the ZSM 5 synthesis results were modified to H ZSM 5 to increase the stability zeolite in thermal or hydrothermal environments. Microporous and hierarchical H ZSM 5 were then used as a catalytic cracking reaction catalyst using n hexadecane as a model compound. Hierarchical H ZSM 5 had the highest conversion that is equal to 84.73 and has the highest percentage of yield and selectivity of gasoline product which is 83.13 and 98.11 , respectively."

"Perkembangan e-learning meningkat setiap tahunnya. tingkat pertumbuhan rata-rata per-tahun sebesar 7,9% dengan total e-learning market 52,5 Miliyar USD di seluruh dunia. Sebagai posisi ke-8 tingkat pertumbuhan e-learning tertinggi di dunia, Indonesia memiliki total e-learning market USD 12,2 miliar dengan tingkat pertumbuhan rata-rata 25% pada tahun 2017. Indonesia memiliki potensi besar untuk mengembangkan e-learning yang lebih besar dan prospektif. Menteri Pendidikan dan Kebudayaan Republik Indonesia berencana menetapkan e-learning secara permanen dengan mengubah pembelajaran tradisional menjadi hybrid learning termasuk pada tingkat sekolah dasar. Tujuan dari penelitian ini adalah untuk merancang rekomendasi strategi yang mempengaruhi penggunaan berkelanjutan untuk menerapkan e-learning di tingkat sekolah dasar. Model konseptual dikembangkan berdasarkan dua teori, yaitu Expectation Confirmation Model of IS Continuance (IS-ECM) dan Information System Success Model (ISSM). Total data responden penelitian ini adalah 195 sampel yang dianalisis menggunakan metode Partial Least Square SEM (PLS-SEM). Hasil penelitian menunjukkan bahwa 4 dari 11 hipotesis ditolak karena tidak memenuhi persyaratan yaitu H1, H4, H7, dan H10. Berdasarkan hasil ini, terdapat 10 rekomendasi strategi yang diajukan dan dinilai oleh beberapa expert. Penilaian menggunakan metode integrasi importance-performance analysis (IPA) dan Kano, dimana terdapat 4 strategi dipilih sebagai prioritas perbaikan dan 3 strategi dipilih sebagai prioritas pertahanan.

The demand for e-learning has increased every year. Its annual worldwide average growth rate is 7.9%, with a total worldwide e-learning market of USD 52.5 billion. As the 8th position of the highest growth rate e-learning worldwide, Indonesia had a total of e-learning market USD 12.2 billion with an average growth rate of 25% in 2017. Indonesia has great potential to develop a bigger and more prospective e-learning business. The Minister of Education and Culture of the Republic of Indonesia plans to set e-learning permanent by changing traditional learning into hybrid learning including at the elementary school level. The purpose of this paper is to design strategies recommendations for increasing continuance intention to apply e-learning at the primary school level. The conceptual model was developed based on two theories: The Expectation Confirmation Model of IS Continuance (IS-ECM) and the Information System Success Model (ISSM). It involved a total of 195 respondents and used the Partial Least Square SEM (PLS-SEM) method for data analysis. The results showed that 4 of the 11 hypotheses were rejected because they do not meet the requirements, such as H1, H4, H7, and H10. Based on these results, 10 strategic recommendations were submitted and assessed by several experts. The assessment was carried out by the integration method of importance-performance analysis (IPA) and Kano, where 4 strategies are selected as improvements strategic priorities, and 3 strategies are selected as keep up the good work strategic priorities."
