Judul: Pembangunan Aplikasi Model Multimarket (Multimarket Express Versi 1.0)
Abstrak: Multimarket model is a model that simulates the impact of price or quantity of one comodity to other comodities. For an example, a decrease in corn price has an impact on the price of rice as a competitor. The multimarket model were developed by InterCAFE LPPM IPB. Currently, the implementations of multimarket model was used in InterCAFE is using Microsoft Excel. The study focus on developing a multimarket model application system, so that it could supports the researcher in simulating the changes impact of price or quantity of one or more comodities. This research uses The Prototyping Oriented Software Development Methodology, VB.Net as programming language, and Microsoft Access as the DBMS. Prices, commodities ela sticity, household’s income, and total demand were used as input of this system. The output produced were the percentage effect of a changes of comodities to others comodities. This system is tested using white box, black box and heuristic evaluation (questionnaires). White box testing is applied to multiplication and matrix inversion. The result of the black box testing shows that every tested function is working properly as expected with 99.32% accuracy rate compared to the Microsoft Excel simulations. On the other hand, the result of the heuristic evaluation using questionnaires shows that 58% of the respondents said that they were satisfied, 27% less satisfied and the rest was not satisfied. Based on the result of the study, it can be concluded that this system may facilitate the users in performing data management and simulation. However, this system still have a deficiency, in that it cannot change the pre-determined model. Hence, further study can be done to develop an application with a dynamic modeling system.

Judul: Pembangunan Prototipe Sistem Aplikasi Mobile Pedagang Sayur Keliling dengan Pendekatan Experiential Marketing
Abstrak: Penggunaan aplikasi e-commerce di Indonesia untuk membeli bahan pokok terus meningkat dari waktu ke waktu dan semakin digemari ketika pandemi terjadi, kemudahan produk yang langsung sampai di depan rumah menjadi alasan aplikasi ini diminati. Sayangnya pelanggan tidak bisa berinteraksi langsung dengan produk yang mereka inginkan bila hanya melalui layar smartphone. Sebaliknya, pedagang sayur keliling bisa memberikan pengalaman tersebut untuk pelanggan tetapi kehadirannya yang tidak menentu menyulitkan pelanggan untuk berbelanja. Penelitian ini bertujuan untuk membangun prototipe sistem aplikasi mobile pedagang sayur keliling sehingga masyarakat bisa berbelanja dengan berinteraksi langsung dengan produk secara efisien. Aplikasi ini telah dikembangkan dengan framework React Native dan sudah diuji oleh empat client. Setelah dua iterasi pengembangan dengan metode prototyping, aplikasi sudah memenuhi seluruh kebutuhan yang diinginkan client dan harapannya bisa diterapkan sebagai model bisnis baru antara pelanggan dan pedagang sayur keliling di Indonesia., The utilization of e-commerce applications in Indonesia for buying daily needs is getting higher day by day and even more popular during the pandemic, convenient products delivery to the customer’s front door becomes a reason why these applications are loved. Unfortunately customers cannot directly interact with the products they want through a smartphone screen. On the other hand, vegetable peddlers are able to give this experience to customers but their uncertainty to be present makes it difficult for customers to shop. This research’s objective is to develop a mobile application prototype system for the vegetable peddler so people can shop by interacting directly with the products efficiently. These applications have been developed using React Native framework and have been tested by four clients. After two iterations of development with prototyping methods, applications have fulfilled all requirements which clients want and hopefully can be implemented as a new business model between customers and vegetable peddler in Indonesia.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
