Judul: Mobile Business Analytics System for Service Level Analysis of Customer Relationship Decision (A Case Study PT Y)
Abstrak: Business Analytics (BA), which is a part of the Business Intelligence (BI), is one form of analysis that can be used on determining the relationship between company and their customers. BA is a concept that also can be used to improve the relationship with customers based on analysis of data. This research aims to identify services that determine the level of customer satisfaction and the pattern of satisfaction level with the services, which the analysis will be integrated into the mobile application. System analysis must be done first before building the apps. Identification was done by distributing questionnaire against customers using Liker scale and the result was analysed using Relief method. The result of Relief would show the attributes that affect the level of customer satisfaction. Decision Tree is used to recognize the pattern of satisfaction level. Result shows that there are 9 from 18 attributes of service affecting customer satisfaction. There are six pattern for determining customer satisfaction level obtained from DT calculation. In addition, mobile applications containing the model to perform the analysis are build in Java Programming Language

Judul: Implementasi Perbaikan Layanan Menggunakan Metode Analisis Bertahan (Survival Analysis) Pada PT Mitra Nasional Kualitas
Abstrak: Keeping customer satisfaction are important thing to maintain customer loyalty by implementing Customer Relationship Management (CRM). CRM is the main objective to improve customer retention through improved customer satisfaction. Provide appropriate services to gain customer satisfaction. Given appropriate services based on customer ratings of the importance of the level of service variables. In addition, service evaluation is done by applying the method of survival analysis, information on the decline gets customer satisfaction based on customer retention. The purpose of this study was to assess the variables that are important to customer service. Then, the implementation needed to build a recovery service is based on the 4P's of marketing aspects of the company. Research at the National Quality Partners, Ltd. Jakarta, show resulting in customers assess the reliability and security attributes of the service is very important variable. Decline in retention rates and survival rates as well as the slope indicates the level of danger that companies need to do a recovery service. recovery services performed by approaching the 4P's of marketing with services variables that are considered important. then be sorted by priority service which should be rectified by the company using the Analysis Hierarchy Process (AHP).

Judul: Sintesis 6-Bromo-4-O-metilkoniferil Alkohol dan trans-Sinamat-nya sebagai Prekursor ke Analog Podofilotoksin
Abstrak: Podofilotoksin merupakan lignan utama dalam resin podofilin yang diekstraksi dari tumbuhan Podophyllum. Toksin ini memiliki aktivitas antivirus, antitumor, antijamur dan antikanker. Berbagai upaya menyintesis podofilotoksin secara kimia telah banyak dilaporkan. Eugenol yang memiliki kerangka fenilpropena dapat digunakan sebagai bahan awal untuk sintesis podofilotoksin berdasarkan keberadaan kerangka dimer fenilpropanoid. Penelitian ini bertujuan menyintesis prekursor untuk sintesis analog podofilotoksin, 6-bromo-4-O-metilkoniferil alkohol dan ester trans-sinamat-nya, dari bahan awal eugenol. Senyawa alkohol target berhasil disintesis dalam 3 tahap, yaitu brominasi, dehidrobrominasi-substitusi, dan hidrolisis, dengan rendemen keseluruhan 34% dari tribromida metileugenol. Sementara produk ester trans-sinamat belum dapat ditentukan rendemennya karena belum semua fraksi dapat dimurnikan sebagai akibat dari pandemi Covid-19. Isomerisasi asam trans-sinamat dan esterifikasi isomer-cis yang diperoleh dengan 6-bromo-4-O-koniferil alkohol serta penuntasan pemurnian ester trans-sinamat merupakan rencana pekerjaan selanjutnya.
