Abstract
For the first time, well ordered zink oxide nanoparticle was synthesized by soft template technique using gelatin as co template. The structure of nanoparticle were characterized by Fourier transform infrared spectroscopy, XRay diffraction, transmission electron microscopy, nitrogen adsor[tion desoprtion tevhniques and scanning electron microscopy. Elementalo analysis on surface monitored by EDAX showed that pure particle produced by the first step produces by self assembly route. However, the process is affaected by block copolimer infiltration into zink precursor which make the Zn bulk formation. In another approach, the using gelatin as template had big effect on the morphology and structure on the nanoparticle. The structure of nanoparticle that synthesized by gelatin involving showed significantly enhanced textural morphologies than zink oxide without gelatin. F future application, nanoparticle using gelatinn as co template can be new candidate of the green material in the future

Abstract. Sending a message via e-mail is the most efficient, faster, and cheaper. Email is a communication tool, file transfer, as well as advertising media through the internet. With the advantages of e-mail, not all users take advantage of the good email. Many users send emails with messages containing viruses, advertisements, and fraud. This email is called spam email. To overcome this problem. To solve this problem, it should be made a research to develop an application of text mining using Support Vector Machine (SVM) method that is capable of classifying to differentiate between spam and non-spam emails according to specific criteria. Text mining is the process of data mining in the form of text where the source data is usually obtained from the documents and the goal is to find words that can represent the contents of the document so it can be analyzed connectedness between documents. In text mining process includes the process tokenisasi, stemming and filtering. Data were collected by literature methods. Thus, the system offered will be able to classify spam and non-spam emails if that happens.

Abstract
The new era of Industry 4.0 is marked by, among others, digitalization and automation in every aspects. For banking industry, this era offers a great opportunity by providing technology-based governance tools. This governance technology has changed the way banks operate and offer products and services to their customers by reducing geographical constraints and the costs of financial transactions. Although the importance of technology in the banking industry is widely recognized, concern for the challenges in this digitalization and automation era in the Islamic banking sector is still not well developed. This study is conducted to investigate the factors influencing Islamic bank-s consumers in adopting online internet banking. To test the hypotheses developed, this study uses the extended theory of The Unified Theory of Acceptance and Use of Technology (UTAUT) consisting of expected performance, effort expectations, social influences, facility conditions, and religious factors. This study utilizes 250 Islamic banking customers as the sample, gathered from Bandung and Jakarta. Using Partial Least Square Modelling as the data analysis method, the results reveals that the expected performance and religious factor are the most important determinants for Islamic banking customers to adopt online services. This research extends the existing knowledge of internet banking adoption in the context of Islamic banking. From a practical perspective, this study provides a guidance and strategy for Islamic bank managers to encourage their customers to adopt online internet banking services.

Abstract
Universities cannot be separated from the existence of assets owned, by seeing so many assets and development opportunities, there are often mistakes in planning, procurement, and inventory of data relating to assets. Sekolah Tinggi Pariwisata National Hotel Institute (NHI) Bandung is a College that organizes professional education programs in the field of tourism. In implementing its business processes, STP involves supporting assets owned by the State managed by the State Property section(BMN). In managing assets which include the process of registration, request, acceptance, and maintenance of BMN goods still use the written recording process in the paper, as well as the process of making reports still using Microsoft Excel applications taken from the data written on the paper. From these problems, BMN requires a computerized information system design. System analysis methods use Object Oriented Analysis and Design (OOAD), and Unified Modeling Language (UML). The results of this study are to design an asset management information system in the form of desktop-based application design. So that it can be used as a reference in implementing it into the application. With the application, it can facilitate BMN in making reporting related to asset control and management

In this study, mesoporous carbon is used to adsorb Ibuprofen using hexan solvent and the temperature variation experiment at 0°C, 37°C, and 45°C as the innovation of the drug delivery system. The drug delivery system is evaluated in a simulated body fluid after ibuprofen loading process. The results of the experiments showed that the optimum adsorption capacity of the trial temperature is 45°C it was due to a relationship between temperature and surface tension.
