ANALISA PENGEMBANGAN SISTEM PAKAR UNTUK DIAGNOSA PENYAKIT PADA BURUNG WALET BERBASIS APLIKASI BERGERAK

Tujuan penelitian adalah untuk mengdiagnosa penyakit pada burung walet yang di tandai dengan adanya gangguan pada burung walet. Hal ini dapat memberikan dampak yang buruk apabila terganggunya pertumbuhan pada burung walet. Maka dari itu penulis membuat sistem pakar agar mengetahui bagaimana cara mengatasi setiap penyakit yang ada pada burung walet serta solusi penanganannya. Sistem pakar ini dikembangkan dengan menggunakan metodologi pengembangan sistem RUP (Rational Unified Process) dengan tahapan sebagai berikut, yaitu fase inception, elaboration, construction, dan transition. Aplikasi ini dirancang dengan menggunakan bahasa pemrograman Java. Penentuan penyakit burung walet dalam sistem pakar ini dilakukan melalui proses konsultasi antara sistem dengan pengguna. Sehingga diharapkan sistem pakar ini dapat memberikan informasi dan penanganan secara dini jika anak terdeteksi mengalami gangguan pada burung walet

Striking Down Physician-Only Laws: A Necessary and Constitutionally Required Answer to the United States’ Critical Abortion Provider Shortage

In 2020, women in South Dakota were deprived of an abortion provider in their state for seven months because the pandemic prevented out-of-state physicians from traveling. And as of late 2021, multiple states had only one abortion provider: if just one physician left, entire states or regions would be cut off from abortion access. The dearth of abortion care is not just caused by the pandemic or the escalating state-imposed restrictions on clinics that force them to close: it is the fact that laws in thirty-six states limiting the provision of abortion to physicians exclude an entire group of practitioners willing and able to safely administer early-term abortions. Including advanced practice clinicians (APCs)—who hold master’s or doctoral degrees—in the provision of first-trimester abortion will ameliorate the United States’ abortion provider shortage, especially for marginalized women. Excluding APCs from abortion care is not just impractical: it is also unconstitutional. Since the Supreme Court made clear in Whole Woman’s Health v. Hellerstedt that medical evidence must support a state’s health-motivated abortion restriction, physician-only laws cannot pass constitutional muster. It is well established that there is no difference in health outcomes between APC and physician-administered first trimester abortions. But the Supreme Court overturning Roe. v. Wade signals an unwillingness to appropriately follow bedrock abortion precedent, meaning that federal and state legislatures must also repeal physician-only laws in the case that the Supreme Court continues to disregard long-standing precedent

Penelitian ini didasarkan atas permasalahan kesulitan belajar dan rendahnya pemahaman siswa SMA pada konsep kelarutan dan tetapan hasil kali kelarutan. Tujuan penelitian ini untuk menyusun desain didaktis yang meminimalkan learning obtacles yang ada dan sesuai dengan karakteristik siswa SMA, mengetahui karakteristik respon siswa dan self-reflection guru dengan lesson analysis dari implementasi pada konsep kelarutan dan tetapan hasil kali kelarutan. Metode yang digunakan pada penelitian ini adalah metode kualitatif dengan Didactical Desain Research. Penelitian ini dilakukan di kelas XI IPA2 SMA Laboratorium Percontohan Universitas Pendidikan Indonesia. Teknik pengumpulan data yang digunakan adalah tes, observasi, lesson analysis, wawancara dan dokumentasi. Hasil penelitian didapatkan 4 karakteristik learning obtacle yaitu learning obstacle terkait connection, learning obstacle terkait conceptual, learning obstacle terkait contruction, learning obstacle terkait struktural. Bentuk desain didaktis yang dikembangkan adalah dengan pemberian fenomena yang diikuti dengan percobaan dengan apersepsi yang menggali pengetahuan siswa yang terkait dengan konsep kelarutan dan tetapan hasil kali kelarutan. Desain didaktis disajikan dalam bentuk chapter design dan lesson design yang telah disesuaikan dengan karakteristik siswa kelas XI IPA2 SMA Laboratorium Percontohan Universitas Pendidikan Indonesia. Implementasi dari desain didaktis ini yaitu berkurangnya learning obtacle dan meningkatnya kemampuan siswa yang semula kebanyakan di kategori kemampuan 1, 2 dan setelah implementasi rata-rata meningkat di kategori kemampuan 3, 4. Lesson analysis pertemuan pertama ini lebih mengarah ke sesi klasikal dikelas dengan intrepretasi berpusat pada guru dan siswa bila dibandingkan dengan sesi kolaborasi sedangkan lesson analysis pertemuan kedua lebih mengarah pada interpretasi kolaborasi. Self-reflection yang didapatkan secara umum adalah penekanan pada materi terdahulu yaitu kesetimbangan kimia terutama dalam penulisan reaksi kesetimbangan dibagian apersepsi pembelajaran. Kata-kata Kunci : Desain Didaktis, Lesson Analysis, Learning Obstacle, Self-reflection, Kelarutan dan Tetapan Hasil Kali Kelarutan This study was based on student’s learning obstacle and the student’s low understanding on solubility and solubility constant product concept. The aim of this study is to arrange didactical design for minimalizing identified student’s learning obstacle and based on student’s characteristic, to know characteristic of student response dan teacher’s self reflection through the implementation of lesson analysis on solubility and solubility constant product concept. The method used in this study was qualitative descriptive method with Didactical Desain Research (DDR) approach. This study was conducted on students of grade XI2 at Senior High School Indonesia University of Education (UPI). The data was collected by test, observation, lesson analysis, interview, and documentation. Findings of this study showed the characteristic of student’s learning obstacle; learning obstacle about connection, learning obstacle about conceptual, learning obstacle about contruction, learning obstacle about structural. Didactical design developed in this study was giving phenomenon in experiment activity that explored student’s understanding on solubility and solubility constant product concept. The didactic design was presented on the form of chapter design and lesson design which had been suited with the characteristics of students of grade XI2 in Indonesia University of Education (UPI) Senior High School. The implementation of didactical design showed the decrease of student’s learning obstacles and the increase of students’ understanding which the ability category was at 1, 2 before the implementation and advanced to 3, 4 after the implementation. Lesson analysis on the first meeting tended to be teacher centered learning on classical session and students collaboration on grouping session. Lesson analysis on second lesson meeting tended to be students centered learning on classical session and students collaboration on grouping session. Teacher’s Self-reflection based on lesson analysis was an affirmation on previous concept about chemical equilibrium and chemical equation concept on appperception activity.

Leaf Spring Damages Analysis on Four Wheel Vehicle

Leaf spring is a component that accept dynamic loads and provide driving comfort. Leaf springs that have been used for a long time will experience a decrease in the quality that causes fracture. The test of leaf spring includes chemical composition, hardness, fractography and metallography. The results show leaf spring is medium carbon steel of 0.47% C, the average hardness value of broken leaf springs is 419.7 means does not experience significant changes, the microstructure of broken leaf springs was tempered martensitic, has corrosion attack, trans granular cracking, secondary crack and crevice corrosion,  and the fracture first occurred in the upper position of the middle leaf springs, while the remaining fractures were at the edges, there was also a corrosion attack on the bottom of the leaf springs, forming rough holes. The initial fracture is marked by the presence of a beach mark. This shape is a characteristic of fatigue fracture.

K-MEANS ALGORITHM DATA MINING IN SALES LEVEL ANALYSIS

In this research, data collection and processing of sales of electronic goods were carried out with CV. Berkah Elektronik. The data obtained is then aggregated with the K-Means algorithm to gain knowledge about which electronic products are selling well on the market and which are not. In this study, the clustering method was used with Tanagra 1.4.48 software, and the K-Means algorithm was used as an algorithm to draw conclusions about which items were selling well and which were not inputted, namely product prices. goods and sale of goods. And from the results of testing and manual testing with the Tanagra application, the same clusters are produced, namely, products that do not sell well (Cluster_KMeans_1) and products that sell well (Cluster_KMeans_2)
