Judul: Needietary: Aplikasi Penyedia Kebutuhan Diet
Abstrak: Sejalan dengan pertumbuhan ekonomi, jumlah penduduk yang tergolong berat badan berlebih dan obesitas mengalami peningkatan. Hal ini mendorong meningkatnya kebutuhan akan program diet untuk mengatasi masalah berat badan lebih dan obesitas. Dalam melakukan program diet untuk menurunkan berat badan, seseorang sering kali menghadapi kendala dan permasalahan, sehingga perlu aplikasi untuk membantu pelaksanaan program dietnya.

Metode yang digunakan dalam penelitian ini adalah customer development yang berfokus pada tahapan customer discovery. Pengambilan sampel dilakukan dengan purposive sampling sebanyak 30 responden di daerah Jakarta. Hasil pada penelitian ini menunjukkan bahwa terdapat beberapa permasalahan saat menjalani diet dengan dua permasalahan tertinggi yaitu kesulitan menentukan menu diet dan bosan dengan menu makanan diet. Berdasarkan permasalahan yang diperoleh berdasarkan informasi diperoleh dari responden, disusun prototype aplikasi Needietary yang dirancang untuk mengatasi permasalahan pelaku diet. Hasil penelitian lainnya adalah teridentifikasinya dan terverifikasinya kanvas model bisnis dalam mengembangkan aplikasi ini sebagai suatu bisnis. Pada penelitian selanjutnya disarankan untuk melanjutkan penelitian ketahapan customer validation., In line with economic growth, the number of people classified as overweight and obese has increased. This has led to an increasing need for diet programs to address the problem of overweight and obesity. In doing a diet program to lose weight, a person often faces obstacles and problems, so an application is needed to help implement the diet program. This study aims to (1) identify the problems experienced by consumers while on a diet, (2) design a diet application prototype that can be a solution to consumer problems when dieting, (3) develop the right diet application business model to solve problems when doing a diet. The method used in this research is customer development which focuses on the customer discovery stage. Sampling was done by purposive sampling of as many as 30 respondents in the Jakarta area. The results of this study indicate that there are several problems when undergoing a diet with the two highest problems, namely difficulty in determining diet menus and boredom with diet food menus. Based on the problems obtained based on the information obtained from the respondents, a Needietary application prototype was developed which was designed to overcome the problems of dieters. Another research result is the identification and verification of the business model canvas in developing this application as business. In further research, it is recommended continuing research on customer validation stages.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
