Judul: Pengembangan Aplikasi Mobile SiTernak untuk Pelaporan Kesehatan pada Hewan Ternak
Abstrak: Pelayanan informasi digital dapat menjadi salah satu upaya peningkatan pengawasan kondisi hewan ternak untuk mengantisipasi kemungkinan penurunan produksi dan kualitas hewan ternak. Akan tetapi, layanan sistem informasi bagi hewan ternak di sejumlah daerah belum dilakukan secara efisien. Di banyak daerah di Indonesia, pengawasan kondisi hewan ternak oleh pemerintah setempat masih dilakukan secara manual sehingga berakibat pada panjangnya proses pelaporan kasus kepada dinas-dinas yang melakukan tindak lanjut terhadap masalah peternakan. Hal ini menunjukkan bahwa diperlukan improvisasi dalam proses pelaporan penyakit pada ternak agar data yang didapat lebih aktual dan terpusat. Penelitian ini berhasil merancang aplikasi mobile yang berguna untuk membantu pelaporan kesehatan hewan ternak melalui fitur utama berupa pelaporan kesehatan. Dengan menggunakan Kotlin pada sisi front end dan JavaScript pada sisi back end, aplikasi memanfaatkan REST API untuk meneruskan permintaan dari sisi pengguna ke database. Pengembangan selesai dilakukan dengan menghasilkan 9 endpoint API dan melewati 18 skenario kasus dengan output sesuai dengan yang diharapkan., Digital information service can be a way to improve the livestock condition monitoring to anticipate the possibility of decreased production and quality of livestock. However, the information system services for livestock in many regions have not been implemented efficiently yet. In some regions we can find in Indonesia, the livestock condition’s monitoring process is still carried out manually by the government, causing a long process of cases reporting until it can be heard by those who take responsibilities of doing the follow-ups toward livestock’s problems (dinas). This shows that improvisation is needed in the process of acquiring disease data on livestock so that the data obtained is more actual and centralized. This research has succeeded in designing a mobile application as a tool for acquiring livestock’s health data through health reporting feature as the main feature. Using Kotlin for the client side and JavaScript for the server side, this application utilizes REST API to forward requests from the user side to the database. This development resulted 9 API endpoints and had going through 18 case scenarios with expected outputs.

Judul: Rancang Bangun Aplikasi Pendataan Ternak Sapi Potong Menggunakan RFID Berbasis Android
Abstrak: Usaha peternakan sapi potong terbagi atas dua sektor, yaitu usaha ternak sapi potong rakyat dan perusahaan. Sebagian besar peternakan sapi potong di Indonesia merupakan peternakan rakyat. Pola pemeliharaannya masih tradisional, serta kepemilikan jumlah ternak yang terbilang masih sedikit antara 2-3 ekor/peternak. Karena kurangnya pengawasan dan kontrol terhadap ternak, standar mutu hasil ternak menjadi salah satu permasalahan yang mempersempit lingkup pasar dari usaha ternak sapi potong rakyat. Penelitian ini bertujuan untuk merancang dan membangun aplikasi berbasis Android yang dapat dipergunakan untuk membantu para peternak tradisional untuk mencatat dan mengakses data ternak sapi potong. Pendekatan dalam tahap perancangan aplikasi menggunakan metode pengembangan System Development Life Cycle (SDLC) yang terdiri dari investigasi sistem, analisis sistem, desain sistem aplikasi, implementasi sistem aplikasi, dan pemeliharaan sistem aplikasi. Hasil dari penelitian ini adalah aplikasi yang dapat mencatat dan menyajikan data ternak sapi potong sesuai dengan EPC pada label RFID yang dimiliki., The beef cattle farming business is divided into two sectors, namely the small-scale farmers and companies. The majority of beef cattle farming in Indonesia is carried out by small-scale farmers, with traditional breeding methods and a small number of cattle per farmer, usually between 2-3 heads of cattle. Due to the lack of supervision and control over the cattle, the quality standards of the cattle become one of the problems that narrow the market scope of small-scale beef cattle farming. This research aims to design and build an Android-based application that can be used to help traditional farmers record and access data on beef cattle. The approach in the application design phase uses the System Development Life Cycle (SDLC) method, which consists of system investigation, system analysis, application system design, implementation of the application system, and maintenance of the application system. The result of this research is an application that can record and present data on beef cattle according to the Electronic Product Code (EPC) on the RFID tag that the cattle have.

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.
