Judul: Design of Information System for Farmers Group Corn Production Based on AppSheet.
Abstrak: Jagung merupakan bahan pakan utama unggas yang digunakan sebagai bahan penyusun ransum. Jagung dibudidayakan oleh petani yang tergabung dalam kelompok tani. Saat ini pencatatan tanam dan panen oleh petani masih dilakukan secara manual. Catatan ini kemudian dihimpun dalam pelaporan data kelompok tani dan juga laporan tanam dan panen komoditas jagung tingkat Kecamatan dan Kabupaten. Dibutuhkan sistem yang dapat membantu kelompok tani budidaya jagung melakukan beberapa penginputan, pengolahan, dan pelaporan data dengan mudah, cepat, dan bisa dilakukan menggunakan smartphone seperti merekap data tanam dan panen. Data yang diinput akan di proses sehingga menghasilkan informasi yang dibutuhkan oleh pemerintah daerah. Tahapan penelitian mengacu pada metode System Development Life Cycle (SDLC). Penelitian ini melalui tahap identifikasi masalah, analisis sistem, desain sistem, implementasi sistem, evaluasi sistem sampai aplikasi memenuhi kebutuhan. Hasil dari penelitian ini adalah sebuah aplikasi Appsheet yang dapat melakukan penginputan data, melakukan prediksi panen, serta pelaporan data tanam dan panen berbasis level organisasi dan waktu. Berdasarkan pengujian langsung yang dilakukan oleh masing-masing user didapatkan hasil bahwa aplikasi sangat mudah dijalankan, mempunyai tampilan yang menarik, dan memenuhi kebutuhan user., Corn is the main feed ingredient for poultry which is used as a building block for rations. Corn is cultivated by farmers who are members of farmer groups. Currently the planting and harvest recording by farmers is still done manually. These records are then compiled in the reporting of farmer group data as well as reports on planting and harvesting of corn at the district and district levels. A system is needed that can help corn cultivation farmer groups to input, process, and report data easily, quickly, and can be done using a smartphone, such as recording planting and harvesting data. The data inputted will be processed to produce the information needed by the local government. The research stage refers to the System Development Life Cycle (SDLC) method. This research through stages problem identification, system analysis, system design, system implementation, system evaluation until the application meets needs. The result of this research is an Appsheet application that can input data, predict harvest, and report planting and harvest data based on organization level and time. Based on direct testing carried out by each user, the results show that the application is very easy to run, has an attractive appearance, and meets user needs.

Judul: Android Based Sugarcane Cultivation Information System Design
Abstrak: Gula merupakan salah satu bahan pokok yang memiliki tingkat kebutuhan tinggi di Indonesia. Ketersediaan gula di Indonesia belum mencukupi kebutuhan nasional. Salah satu bahan pembuatan gula adalah tebu. Produksi tebu sebagai bahan pembuatan gula yang maksimal pada tingkat desa dapat membantu pemerintah dalam memenuhi kebutuhan gula nasional. Produksi tebu yang maksimal dapat dipenuhi dengan melakukan manajemen data lahan tebu pada tingkat desa. Penelitian ini bertujuan untuk merancang sistem informasi berbasis android pada budidaya tebu tingkat desa yang dapat memaksimalkan manajemen data lahan tebu. Tahapan penelitian ini terdiri dari identifikasi masalah, analisis sistem, desain sistem, implementasi sistem, dan pengujian sistem. Penyususnan basis data menggunakan bahasa pemrograman terstruktur pada webhost untuk menyusun basis data, relasi antar data, dan akses pengguna. Sistem informasi budidaya tanaman tebu berbasis android telah diimplementasikan berbasis android dan telah diuji sistem. Berdasarkan uji sitem aplikasi ini dapat menampilkan informasi berupa data pengguna, data lahan, data pengolahan lahan, data pemupukan, data panen, dan data penjualan bekerja dengan baik., Sugar is a staple that has a high level of need in Indonesia. The availability of sugar in Indonesia is not sufficient for national needs. One of the ingredients for making sugar is sugar cane. Sugar cane production as a material for making maximum sugar at the village level can assist the government in meeting national sugar needs. Maximum sugarcane production can be met by managing data on sugarcane fields at the village level. This study aims to design an Android-based information system for sugarcane cultivation at the village level that can maximize sugarcane land data management. The stages of this research consist of problem identification, system analysis, system design, system implementation, and system testing. Database development uses structured query language on the webhost to compile databases, relationships between data, and user access. An Android-based information system for sugar cane cultivation has been implemented based on Android and the system has been tested. Based on the system test, this application can display information in the form of user data, land data, land processing data, fertilization data, harvest data, and sales data.

Judul: Perbandingan Model HIV dengan dan tanpa Waktu Tundaan
Abstrak: Acquired immunodeficiency syndrome (AIDS) is the reduction of the human immune system. AIDS is caused by human immunodeficiency virus (HIV). No medicine has been found for this desease until recently. An AIDS therapy is usually performed with highly active antiretroviral therapy, namely reverse transcriptase inhibitors, protease inhibitors and combination of both. Various models have been developed to explain the immune system of patients with AIDS, namely the HIV, response and the time delay model. This paper discusses the comparison between the dynamics of the HIV virus, the dynamic response of protease inhibitors and dynamics of time delay. The dynamics model of HIV is influenced by the level of white blood cells produced and the rate of its death. Dynamics of protease inhibitors on the response and the time delay model is influenced by the death rate of infected white blood cells and the failure rate of treatment.
