  • Deteksi Area Pendaharahan Otak Pada CT Scan Kepala (Otak) Menggunakan
           Metode K-Means Clustering

    • Authors: Nur Fadillah Bustamin, Nur Inayah Yusuf, Sri Rahayu, Andi Baso Kaswar
      Pages: 1 - 8
      Abstract: Abstrak. Pendarahan otak merupakan salah satu penyakit yang sangat berbahaya karena otak merupakan salah satu organ paling vital bagi manusia. Dalam penanganannya, pendarahan otak dapat di ketahui melalui CT Scan kepala yang dilakukan di rumah sakit. Namun pemeriksaan melalui CT Scan tidak dapat mengetahui atau mendiagnosis letak atau area pendarahan otak yang terjadi, sehingga dibutuhkan suatu teknologi yang dapat mengatasi masalah tersebut agar penanganan terkait pendarahan otak dapat dilakukan dengan cepat, tepat dan efisien. Pada penelitian ini, dibuat sebuah pengolahan citra digital untuk mendeteksi area atau letak pendarahan otak pada citra CT Scan menggunakan metode kmeans clustering. Metode yang digunakan terdiri dari proses segmentasi menggunakan k-means untuk memisahkan objek pendarahan dan background, kemudian proses deteksi menggunakan region props untuk memberikan label objek pada hasil segmentasi pendarahan otak sebelumnya. Berdasarkan hasil uji coba program dengan 20 data uji citra diperoleh rata-rata akurasi yaitu sebesar 90%. Hal tersebut menunjukkan bahwa proses deteksi area pendarahan otak yang diusulkan memiliki akurasi yang tinggi, sehingga dapat memberikan hasil yang lebih akurat dan proses yang lebih cepat.Keywords: CT Scan Pendarahan Otak, Algoritma K-Means Clustering, Pendarahan Otak

  • Perbandingan Metode Klasifikasi Maximum Likelihood dan Support Vector
           Machine dalam Pemetaan Genangan Banjir (Studi Area: Kawasan Danau Tempe)

    • Authors: Nur Yani, Sulistiawaty Sulistiawaty, Usman Usman
      Pages: 9 - 17
      Abstract: Abstrak. Penelitian ini bertujuan untuk mengetahui  potensi Citra Sentinel-1a menggunakan metode klasifikasi maximum likelihood dan metode klasifikasi support vector machine dalam mengindentifikasi genangan banjir  serta memban-dingkan ketelitian dalam pemetaan genangan banjir  di sekitar kawasan Danau Tempe. Untuk mencapai tujuan tersebut telah digunakan data citra sentinel-1A dengan akuisisi 3 Maret 2018 (sebelum banjir) dan 26 Mei 2018 (pada saat banjir). Data tersebut diambil, diolah, dan dianalisis di Lembaga Penerbangan dan Antariksa Nasional (LAPAN) kemudian mengecek dan mencocokkan kembali  data di lapangan. Data yang diperoleh diolah melaui tahap pengolahan awal interpretasi citra sentinel adalah Preprocessing data Sentinel-1A dengan menggunakan perangkat lunak SNAP 7.0.  Selanjutnya menggabungkan citra pre-flood dan post-flood menggunakan stack tools di software SNAP untuk menyatukan kedua citra tersebut menjadi satu citra. Citra hasil stacking selanjutnya dikomposit ke RGB, selanjutnya digunakan dua metode klasifikasi terbimbing yaitu maximum likelihood dan support vector machine. Hasil penelitian yang diperoleh adalah metode Maximum Likelihood dan Support Vector Machine (SVM) berpotensi mengidentifikasi genangan banjir dengan    nilai akurasi pemetaan genangan banjir pada metode  Support Vector Machine (SVM) lebih tinggi dibandingkan dengan metode Maximum Likelihood (MLC) dengan nilai akurasi metode SVM sebesar 50% dan  metode MLC sebesar 42.3%. Kata Kunci: Banjir, Citra Sentinel-1A, MLC, SVM

      Pages: 38 - 42
      Abstract: Abstract. Belajang Susu Plant (Scindapsus pictus Hassk.) is a species of the genus Scindapsus including the Araceae family which has been traditionally used by the Mambi people for medicine. Plants from the genus Scindapsus contain active compounds such as calcium oxalate, flavonoids sulfate and a mixture of flavones and flavonols sulfate which can be used as anti-inflammatory, analgesic, antioxidant, anticancer and anti-tumor. This study aims to determine the potential of methanol extract of Scindapsus pictus Hassk. as an anticancer. Extraction was carried out by maceration with methanol and then tested for cytotoxicity against MCF-7 cancer cells. The results showed that the methanol extract of Scindapsus pictus Hassk. was very active against MCF-7 breast cancer cells with an IC50 value of 3.9861 μg / mL. Keywords: Belajang susu,  Scindapsus pictus Hassk., MCF-7The first section in your paper

  • Comparative Analysis of Temperature External and Internal and Relative
           Humidity of Electric Egg Incubator

    • Authors: Zulhajji Zulhajji, Muliyati Yantahin
      Pages: 84 - 94
      Abstract: Abstract. This study aimed to determine the ratio of external and internal temperatures and the humidity of the electric egg incubator. This research was designed in three stages. The first stage is the manufacture of an egg incubator, followed by the testing and analysis stage. Based on the data from the measurement and analysis results, it was found that the temperature and humidity in the incubator greatly influenced the quality of the hatching of native chicken eggs. This study used an experimental method and was carried out twice. The first stage of testing and measurement data obtained an average external temperature of 28.5°C, internal 38.2°C, and the humidity of the air in the hatchery room was 56.0%. In contrast, the second stage of testing and measurement obtained data on an average outside temperature of 28.42°C, inside 38,0°C, and humidity in the hatchery room 56.0%. It can be concluded that the ratio of outside and inside temperatures in the incubator must be balanced until the 21st day of hatching. In this case, if the outside temperature rises, the temperature inside the incubator must decrease, with the same relative magnitude. Likewise, the humidity inside must have relatively the same ratio to obtain a perfect hatching process, which is between 50% - 60%.
