Abstract

Pada penelitian ini dilakukan kombinasi steganografi dan kriptografi untuk pengamanan data dengan tidak mengubah kualitas media cover. Metode steganografi yang digunakan dengan melakukan pencocokan bit pesan pada bit MSB citra. Proses pencocokan dilakukan secara divide and conquer. Hasil indeks posisi bit kemudian dienkripsi menggunakan algoritma kriptografi Data Encryption Standard (DES). Masukkan data berupa pesan teks, citra, dan kunci. Output yang dihasilkan berupa chiperteks posisi bit yang dapat digunakan untuk merahasiakan data. Untuk mengetahui isi pesan semula diperlukan kunci dan citra yang sama. Kombinasi yang dihasilkan dapat digunakan untuk pengamanan data. Kelebihan metode tersebut citra tidak mengalami perubahan kualitas dan kapasitas pesan yang disimpan dapat lebih besar dari citra. Hasil pengujian menunjukkan citra hitam putih maupun color dapat digunakan sebagai cover, kecuali citra 100% hitam dan 100% putih. Proses pencocokan pada warna citra yang bervariasi lebih cepat. Kerusakan pesan dengan penambahan noise salt and peper mulai terjadi pada nilai MSE 0,0067 dan gaussian mulai terjadi pada nilai MSE 0,00234.

Abstract

The development of hotel business to make consumers more critical to choose a hotel products and services. If the hotel facilities more complete, so interest of the consumer is higher to choose the hotel. This  research study intend to build a decision support system for the procurement of hotel facilities with TOPSIS method. This method uses the six alternative form of the data; hotel rooms (guest  room), karaoke, gift shop, a gym, spa and travel corner (travel tour information) and data of some criteria. This method was chosen because it is based on the best alternative concept, was not only has the shortest distance from the positive ideal solution, but also has  the longest distance  from  the  negative  ideal  solution.  TOPSIS  calculations  systems  have  been  done  the  comparison  of  final  value  using  excell calculation. Calculations that used in this research study is simple and produces alternative hotel rooms (guest room) with t he highest ranking as the ideal solution. TOPSIS method facilitates decision-makers in choosing the best alternative for the procurement of hotel facilities.Keywords : Decision support system; Hotel facilities; TOPSIS

Abstract

In the development of the information system needed a plan that will complement the university's strategic direction. Planning process utilizing enterprise architecture planning methodologies that produce a conceptual model of the enterprise architecture that includes data architecture, application and technology. This research aim to make enterprise architecture planning a conceptual model of the enterprise architecture as a high-level blueprint for data, applications and technology. Conceptual model enterprise architecture generated can be used as a blueprint for data, applications and technology in the development of information systems. Results of the blueprint enterprise became architecture planning for the needs of the data, estimates of technology platforms and applications as well as other things that are needed in the development of an integrated information system in university.   Keywords:  Enterprise architecture planning; Data architecture; Application architecture; Technology architecture

Abstract

Housing is one of human secondary needs. In selecting the most appropriate housing, there are lots of aspects to be considered to satisfy the costumers  want. In order to get optimal result, a system is needed to help the costumers to decide which housing fit them   most. System that will be built in this thesis is a system that supports costumers’ satisfaction in housing selection. There are 2 main stages in the  system,  namely  data  grouping  and  ranking.  Data  grouping  method  used  is  Fuzzy  C -Means  Clustering  (FCM).  Simple  Additive Weighting (SAW) is used for ranking purpose. Testing is carried out by comparing  interview result with system counting result. The testing result produces 9 cases that derive similar recommendation.Keywords : Housing selection; FCM; SAW; Recommendation; Grouping

Abstract

An expert system is a system that seeks to adopt human expertise so that computers can do things that can be done by an expert to solve specific problems. Experts in this case is an expert in the field to address the problem under on detecting cervical cancer. Cervical cancer is a disease that is very afraid of all women because it attacks the reproductive organs caused by the virus Human Papilloma Virus (HPV). The system is made to detect cervical cancer using the certainty factor with a forward chaining inference engine. Certainty factor method used in cervical cancer detection system to give certainty to the disease. As a result of this information system is to provide information regarding the statement of cervical cancer and cancer treatment solution according to the stage.   Kata kunci : Certainty Factor; Forward Chaining; Kanker Mulut Rahim

Abstract

Procurement of assets by auction requires a decision support in selecting the winning bidder so that decision makers can pick and choose the winner of the auction. This study aims to develop a Decision Support System (DSS), which serves as an aid in decision mak ing in the process  of  evaluating  the  winning  bidder  acquisitions.  In order to  achieve  the  purpose  of  SPK  well  then helped  by  using  one  of  the methods in decision-making that is the method of Simple Additive weighting method (SAW) to evaluate alternatives in the provision of asset  based  decision-making  criteria.  This  method  has  the  advantage  criteria  (benefits)  and  cost  criteria  (cost).  Criteria  advantage (benefit) is used when considering the aspects of decision making maximum profit. While the cost criteria (cost) is the inver se of the attributes of an advantage, in this draft decision will be looking  for a minimal fee. The results may support the decision on the selection of an alternative evaluation of acquisitions winners based on predetermined criteria.Keywords: Acquisitions; Decision support systems; Simple additive weighting

Abstract

Performance evaluation of academic departments in university become routine activity to improve quality service.There qualitative and quantitative aspects to evaluate academic department. As well known that Data Envelopment Analysis (DEA) is one of non parametric technique based on linear programming. In this paper, we study to evaluate the academic departments with data envelopment analysis based on quantitative aspects. We formulate the performance evaluation as DEA problem. There are several stage to build DEA model as tool for the performance evaluation of academic departments. Firstly, we investigate purely quantitative variables in departement as input/output DEA model. Secondly, we discuss several ranking methods of decision making unit (DMU) to obtain efficiency of academic departments. In this paper, we use modified l1-norm method to rank DMU’s in DEA model. Keywords : DEA, DMU, and modified l1-norm method

Abstract

COVID-19 pandemic has changed human life. One of the impacted sectors is education. Ministry of Education urges students to implement distance learning. No exception with early childhood education or Pendidikan Anak Usia Dini (PAUD). Although distance learning has been widely implemented, PAUD sector has the lowest online learning implementation in Indonesia with 13.2% of total 98.4% of PAUD students implementing distance learning, whereas early age is considered capable of gaining an understanding of digital technology and equipment. One possible step in conducting digital learning in PAUD is through a digital educational game, because game is an important element in PAUD. In this study, a digital educational game was developed for TK-A level students using Scratch 3 with multimedia development life cycle method. After development, the game goes through two stages of testing. Alpha testing in the form of black box testing, and beta testing in the form of usability testing with 94,39% result, confidence testing with 97,8% result, and summative evaluation with 90% result on TK-A students, as well as interviews with PAUD teachers. The test results indicate that the game has been successfully developed and is feasible to be played by TK-A students.
