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: Pengembangan Modul Back-End Aplikasi Sistem Enterprise Hortikultura Tingkat Petani dan Kabupaten Menggunakan Metode Prototyping
Abstrak: Cabai merah, bawang merah, dan bawang putih termasuk kedalam komoditas yang berperan besar dalam inflasi di Indonesia. Distribusi cabai merah, bawang merah, dan bawang putih di Indonesia masih perlu dikembangkan karena proses pendataan saat ini masih dilakukan secara manual menggunakan blangko. Proses tersebut dinilai rumit dan memungkinkan terjadinya kesalahan. Sistem enterprise untuk cabai merah sudah dikembangkan, namun belum dilengkapi dengan statistik deskriptif untuk tingkat kabupaten. Oleh sebab itu, diperlukan suatu sistem enterprise yang dapat mendata distribusi komoditas tersebut dan dapat memberikan laporan untuk petugas BPS. Pada penelitian ini, sistem enterprise cabai yang sudah ada akan ditambah dengan komoditas bawang merah dan bawang putih serta akan dibuat fitur statistik deskriptif, penambahan modal, penambahan jenis pupuk, dan ekspor blangko. Pengembangan sistem enterprise dilakukan dengan metode prototyping dengan berfokus pada pengembangan back-end. Hasil dari penelitian berupa enam endpoint API baru yang terdiri dari endpoint tambah modal, edit modal, get modal, delete modal, ekspor blangko, dan statistik. Sebagai kesimpulan, service back- end yang sudah dibuat dapat diakses secara publik dan telah dilakukan pengujian dengan menggunakan integration testing yang terdiri dari 27 kasus uji dan mendapatkan waktu respon total 3,454 detik. Untuk penelitian selanjutnya diharapkan dapat melakukan pengujian pada pengguna langsung supaya umpan balik lebih akurat.

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.
