Tesis ini meneliti mengenai pengaruh pengurangan mineral pengotor pada bentonit menggunakan alat hidrosiklon dan modifikasi pertukaran kation dengan penambahan dosis surfaktan terhadap basal spasi organobentonit yang dihasilkan serta terhadap sifat-sifat dari nanokomposit karet alam/organobentonit. Nanokomposit karet alam/organobentonit dibuat dengan teknik pelelehan kompon. Hasil penelitian menunjukkan proses reduksi mineral pengotor pada bentonit telah mampu mengurangi kandungan senyawa pengotor, seperti Fe2O3, CaO, dan K2O. Sementara itu, peningkatan dosis surfaktan pada bentonit dapat meningkatkan basal spasi pada organobentonit. Organobentonit rendah mineral pengotor ini mampu menghasilkan nanokomposit dengan sifat mekanik yang lebih baik dari nanokomposit berbahan pengisi bentonit alam. ...... This thesis are to studies the effect of the reduction of mineral impurities in the bentonite using hydrocyclone and the effect of cation exchange modification with the addition of surfactant dosage on the basal spacing of organobentonit and the properties of natural rubber/organobentonite nanocomposites Natural rubber/organobentonite nanocomposites made by melting compound technique. The results showed the reduction process of mineral impurities in the bentonite has been able to reduce the content of impurities, such as Fe2O3, CaO, and K2O. Meanwhile, an increase in the dose of surfactant on bentonite may increase the basal spacing of organobentonite. Low mineral impurities organobentonite is capable of producing nanocomposite with better mechanical properties than nanocomposite filled pristine bentonite.

Permintaan daging sapi di Indonesia selalu meningkat dari tahun ke tahun. Tetapi sayangnya persediaan di dalam negeri tidak mencukupi, sehingga impor daging dalam jumlah besar terus dilakukan. Pemerintah telah melakukan berabagai usaha untuk mengurangi impor dan mencapai swa sembada. Saat ini, permerintah sedang menyelenggarakan program Swasembada Daging Sapi (PSDS) 2014. Tetapi, beberapa ketidakakuratan data masih tetap muncul, misalnya antara data yang digunakan di dalam blueprint PSDS 2014 dan data yang dirilis dalam Basis Data Statistik Pertanian (BDSP). Ketidakakuratan data dapat menyebabkan ketidakakuratan kebijakan di sektor peternakan. Oleh karena itu, di dalam disertasi ini, diusulkan suatu konsep e-Livestock untuk mengatasi ketidakakuratan data tersebut. Disertasi ini dilakukan berdasarkan Definition, Framework, Methodology, and Area of concern (DFMA) model of reserach. Ada lima langkah penelitian yang dilakukan di dalam disertasi ini. Pertama, definisi (D) dari e-Livestock diformulasikan. Kedua, definisi tersebut divalidasi dan diperbaiki dengan cara mewawancarai beberapa pakar dan stakeholder, dan hasil wawancara tersebut diinterpretasi menggunakan hermeneutika. Definisi yang sudah divalidasi kemudian digunakan pada langkahlangkah berikutnya. Ketiga, 36 faktor sukses untuk inisiatif e-Government di sintesis menggunakan Meta-Ethnography. Semua faktor sukses tersebut kemudian digunakan di dalam langkah keempat untuk memformulasikan 62 faktor sukses yang spesifik untuk e-Livestock di Indonesia. Semua 62 faktor sukses, multivew framework, dan soft system thinking kemudian digunakan sebagai framework (F) di dalam langkah berikutnya. Di dalam langkah kelima, metodologi (M) bernama Soft Systems Metodology (SSM) digunakan di dalam area (A) yang menjadi perhatian untuk menghasilkan model-model yang terkait untuk e-Livestock di Indonesia. Hasil dari semua langkah penelitian telah menjawab semua research questions dari disertasi ini. Berbagai kontribusi teoritis dan praktis juga telah dihasilkan dan dapat memperkaya ilmu pengetahuan di dalam penelitian e-Government dan dapat membantu pemerintah Indonesia.

The demand for beef resources in Indonesia is always increasing from year to year. Unfortunately, the national beef supply usually did not able to meet those needs. The import of beef in large numbers likely to remain performed. The government has made various efforts to reduce imports and achieve self-sufficiency in beef. Currently, the government has launched the new Beef Self-Sufficiency Program (PSDS), i.e. PSDS 2014. However, some concerns about the data inaccuracies was actually reflected in the difference about beef production data released by Agricultural Statistics Data Base (BDSP) and the data stated in the blueprint of PSDS 2014. Inaccuracy of data can lead to the inappropriate policy making in the livestock sector. Therefore, it is proposed in this dissertation that e-Livestock can help to solve the problem This dissertation are based on Definition, Framework, Methodology, and Area of concern (DFMA) model of reserach. Five main research steps have been conducted in this dissertation. First, the definition (D) of e-Livestock in Indonesia is formulated. Second, the definition then be validated and adjusted by interviewing some stakeholders and experts, and the results of interviews are interpreted using hermeneutic. The resulted definition than used in all other subsequent steps. Third, 36 success factors for e-Government initiative are synthesized using Meta-Ethnography. Those success factors then used in the fourth research steps to formulates the 62 success factors that specific for e-Livestock in Indonesia. These 62 success factors, multivew framework and soft systems thinking then used as the framework (F) of idea in the next research step. In the fifth research step, the Soft Systems Metodology (SSM) is used and combined with some other methods to model the e-Livestock in Indonesia. The results from all research steps have answered all the research questions of this dissertation. Several theoretical and practical contributions have emerged and can enrich the body of knowledge in e-Government research and can take into consideration in practice.

Penelitian ini berfokus pada intensi pembelian konsumen generasi X yang sebagian besar memiliki daya beli yang kuat. Berdasarkan sampel 190 responden generasi X di Indonesia, peneliti menguji pengaruh variabel personal awareness of security, personal innovativeness, perceived ease of purchasing, dan perceived usefulness terhadap online purchase intention dengan menjadikan variabel attitude towards online purchase dan habitual online usage sebagai variabel mediasi dan menggunakan metode analisis data berbasis structural equation modelling SEM. Hasilnya, nilai personal awareness of security yang rendah menunjukkan kekhawatiran konsumen generasi X terhadap situs e-commerce, lalu personal innovativeness dan perceived usefulness menjadi faktor penting yang menentukan intensi pembelian online, sedangkan perceived ease of purchasinghanya berpengaruh secara langsung terhadap intensi pembelian online tanpa dimediasi oleh kedua variabel mediasi. Temuan dalam penelitian ini diharapkan memiliki implikasi bagi para peneliti, pelaku bisnis e-commerce dan pihak ritel dengan target di segmen generasi X, di mana harapannya adalah mereka mampu memahami secara lebih baik karakteristik target konsumennya dan dapat merumuskan strategi online yang lebih baik.

This study focuses on the intention of purchasing of consumer generation X which mostly have a strong purchasing power. Based on a sample of 190 respondents of generation X consumers in Indonesia, the researcher examined the effect of personal awareness of security, personal innovativeness, perceived ease of purchasing, and perceived usefulness toward online purchase intention by making the attitude towards online purchase and habitual online usage as mediator variables and using SEM based data analysis method. As a result, the low personal awareness of security pointed to the worries of generation X consumers on e commerce, on the other hand personal innovativeness and perceived usefulness became important factors in determining online purchasing intention, while perceived ease of purchasing affects directly the intention of online purchase without any mediation on both mediator variables. The findings in this study are expected to have implications for researchers, e commerce and retailers with a target in the generation X consumers, with expectations that they get better understanding of the characteristics of their target customers thus they can formulate better online strategies.
