This study aims to produce products in the form of LKPD SPLDV material, and Know the response of educators to LKPD on SPLDV material. The method of this research is Research and Development (R & D) based on ADDIE model Stages performed only from stage 1 to stage 5 that is from analysis, design, development, implementation, evaluation. The result of the material expert test on the content quality aspect obtained the average score of 3.67 with very good criteria, on the aspect of the accuracy of the scope obtained the average score of 3,167 with good criteria. Expert test media on LKPD size aspect got the average score 4 very interesting, skin design aspect LKPD got average score 3,66 with the good criterion, design aspect of LKPD got average score 3,4167 with good criterion. Expert tests obtained an average score of 3.22 with good criteria. In the small group trial of students in the attractiveness, test obtained an average score of 3.57 with interesting criteria, large group trials of students in the attractiveness test obtained an average score of 3.56 with interesting criteria. From some of the above data, it can be concluded that LKPD developed into good criteria and get a good response for the learners.

This study aims to produce products in the form of bilingual module based on quantum learning on the material opportunities. This research includes the type of research and development (Research and Development) refers to a model consisting of five steps of activities namely analysis, design, development, implementation, and evaluation. The result of the research shows that the module that obtained the average percentage value from the material expert is 83,33% with the very good criterion, the average percentage value from media expert is 85% with very good criteria and the average percentage value from the linguist ie 78.67% with very good criteria. The bilingual module based on quantum learning on the opportunity meters also obtained a percentage value of 80% student response with very good criteria and obtained the percentage value of educator equal to 84% with very good criteria.

This research aims to determine customer perceptions of food outlets located on Lampung Walk and to find out the similarities between food outlets on Lampung Walk using Multidimensional Scaling analysis. The methods used in this reseach are descriptive method and analytic survey using inferential statistics. The research places are the food outlet of Kedai Urang, el's coffee, dimsum moresto, pondok hijau and sup duren ewok. The results of this research known that the highest customer perceptions is in Kedai Urang with affordable price attributes, more portions, good taste, neat and clean presentation. So that for other business developers can pay attention to the attributes of consumer perception for business continuity.

The purpose of this reaserch is to develop teaching materials consisting of pictorial bilingual modules using Realistic Mathematics Education (RME) on set material and to research the effectiveness of the product being developed. The research used in this research is Research and Development using ADDIE models consisting of motion sickness Analysis, Design, Development, Implementation and Evaluation. This study was declared valid and feasible to be used as teaching material for mathematics learning by 3 material experts who obtained an average score of 3,72 in the "valid" category and 3 media experts with an average score of 3,71 in the "valid" category and 3 language experts with an average score of 3,65 with the category of "Valid" with each maximum score of validity is 4. With the test of attractiveness of teaching materials determined "Very Attractive" by a small group test of 9 students by agreeing to the average score average of 3,65 and a large group test of 29 students with approval of an average value of 3,68. The results of the assessment using testing the effect size with an approval score of 0,50 with the category "Effective Enough". So it can be concluded that the development of teaching materials produced is declared feasible and effective enough and can be used as teaching materials in learning mathematics. Abstrak: Tujuan dari penelitian ini yaitu mengembangkan bahan ajar berupa modul bilingual bergambar dengan pendekatan Realistic Mathematics Education (RME) pada materi himpunan serta mengetahui keefektifitasanproduk yang dikembangkan. Penelitian yang digunakan dalam penelitian ini adalahResearch and Development menggunakan model ADDIE yang terdiri dari tahap Analyze, Design, Development, Implementation dan Evaluation. Penelitian ini dinyatakan valid dan layak digunakan secara keseluruhan sebagai bahan ajar pembelajaran matematika oleh 3 ahli materi yang memperoleh skor rata-rata sebesar 3,72 dengan kategori “valid” dan 3 ahli media dengan skor rata-rata sebesar 3,71 dengan kategori “valid” serta 3 ahli bahasa dengan skor rata-rata sebesar 3,65 dengan kategori “Valid” dengan masing-masing skor maksimal kevalidan adalah 4. Sedangkan uji kemenarikan bahan ajar dinyatakan “Sangat Menarik” oleh uji kelompok kecil terhadap 9 orang peserta didikdengan perolehan skor rata-rata sebesar 3,65 dan uji kelompok besar terhadap 29 orang peserta didik dengan perolehan nilai rata-rata sebesar 3,68. Hasil penilaian uji efektivitas dengan menggunakan rumus effect sizedengan perolehan skor sebesar 0,50 dengan kategori “Cukup Efektif”. Sehingga dapat disimpulkan pengembangan bahan ajar yang dihasilkan dinyatakan layak dan cukup efektif serta dapat digunakan sebagai bahan ajar dalam pembelajaran matematika.
