Abstract

Turbin Gas unit (GT. 1.2) PLTGU Cilegon dilakukan Major Inspection Overhaul (MIO) pada (14 September - 6 November) 2019, dari overhaul tersebut akan terjadi perubahan performa pada turbin gas, untuk mengetahui perubahan nya diperlukan analisis perhitungan dan hasil secara termodinamik pada kondisi sebelum (26 Agustus) dan sesudah (12 November) dengan perbandingan grafik terhadap variabel performa yaitu; Efisiensi komponen turbin gas, Spesifik Fuel Consumption, Air Fuel Ratio, Back Work Ratio dan Heat Rate. Data yang digunakan adalah data bahan bakar dan operasi (variasi jam). Pengolahan dan perhitungan data menggunakan Microsoft. Excel dan didapat nilai rata-rata dari variabel performa. Kesimpulannya adalah terjadi peningkatan performa efisiensi; turbin gas sebesar 0.72 %, kompresor sebesar 0.98 %, siklus thermal aktual sebesar 1.06 %. Terjadi nilai tetap pada efisiensi ruang bakar sebesar 100 %. Dan terjadi penurunan nilai; AFR sebesar 0.116, BWR aktual sebesar 0.98 %, SFC aktual sebesar 0.004387, Heat rate aktual sebesar 222.242.

Abstract

In the comprehensive study of the Indonesian coal mining industry, a rigorous exploration and clustering approach was applied to historical stock price data and financial metrics from coal companies listed for over a decade. Data sourced from Yahoo Finance underwent an automated download process, ensuring consistency and efficiency. The research utilized robust clustering techniques, including K-means, Hierarchical, and Correlation Clustering, to discern the stock price movements during the dynamic market conditions of 2022 and 2023. Financial performance analysis, focusing on key metrics such as ROA, NPM, and EPS, highlighted the unique financial dynamics of companies like PTIS, IATA, and AIMS. The study's results provide a multifaceted understanding of the coal industry's financial trends, emphasizing varied company responses to market conditions and revealing significant financial performance divergences among key players. This research not only offers invaluable insights into the coal industry's financial landscape but also presents an innovative methodology poised to transform financial analytics in the sector.

Abstract

ABSTRACT Prostate cancer is one of the most common forms of men's cancer in the world and the understanding of its epidemiology is crucial to effective prevention, early detection and management strategies. This systematic review highlights the potential of artificial intelligence-based diagnostic methods to revolutionize the early diagnosis of prostate cancer. A comprehensive literature search was carried out using databases such as PubMed, Google Scholar and Scopus. After removing duplicates, titles and abstracts were examined in 279 studies and the following full texts were examined in 128 studies. We have ten studies to review in total. Therefore, we chose to review data for all 10 identified studies that applied AI techniques to detect ca prostate. The Paige Prostate Alpha AI system significantly enhances pathologists' diagnostic capabilities, leading to more accurate and effective prostate cancer detection. These limitations indicate that further research is required to address these issues and validate the results in a more diverse and controlled environment. AI-based diagnostic methods have shown significant promise in enhancing the early detection of prostate cancer. As technology continues to advance, integrating AI with traditional diagnostic approaches could lead to more effective, efficient, and accurate prostate cancer screening and diagnosis. Future studies should focus on large-scale clinical trials and real-world applications to validate these findings and facilitate the adoption of AI in clinical settings. Keywords: Prostate Cancer, Artificial Intelligent, Deep Machine Learning, MRI

Abstract

Glide Path bekerja pada frekuensi Ultra High Frekuensi (UHF) antara 309,15Mhz hingga 335,4Mhz dan berfungsi memberikan informasi panduan sudut luncur 3ᵒ saat melakukan prosedur pendaratan agar pesawat mendarat tepat pada touchdown. Pada Perusahaan umum (Perum) Lembaga Penyelenggara Pelayanan Navigasi Penerbangan Indonesia (LPPNPI) Cabang Palembang dalam pelaksanaan perawatan peralatan navigasi diwajibkan mengisi LogBook harian terutama pada peralatan Glide Path merek Selex tipe SI-2100. Sesuai Peraturan Direktur Jendral Perhubungan KP 35 Pasal 12 Tahun 2019 ayat 2 dijelaskan bahwa pada poin b pemeriksaan status indikator dan pembacaan parameter termasuk kedalam pemeliharaan tingkat 1 fasilitas navigasi penerbangan. Oleh karena itu, penulis memiliki ide untuk membuat sebuah rancangan monitoring Battery Charging pada peralatan Glide Path yang dapat memonitoring tegangan pada baterai 1 dan baterai 2 dengan menampilkan informasi suhu, tegangan, arus dan daya secara aman dan mudah. Diharapkan rancangan ini dapat digunakan sebagai monitoring tegangan Battery Charging pada peralatan Glide Path merk Selex agar memudahkan teknisi untuk melakukan perawatan dan memonitoring baterai back up peralatan navigasi Glide Path Selex SI-2100 yang sebelumnya hanya menggunakan avo meter sebagai media alat ukur.

Abstract

The activity was a community service carried out in Bawu Village to a Micro, Small and Medium Enterprises (MSME) with the name Baim¢s Cafe and Bubur Rujak Mbok Siti. The spread of COVID-19 that hit Indonesia had a negative impact on micro-entrepreneurs in Indonesia, especially in Bawu Village. The implementation of Restrictions Towards Community Activities (PPKM) by both central and local governments significantly reduces consumer access to the micro business actors. The purpose of this community service is to increase the entrepreneurial knowledge and skills of business owners in selling through social networking. This service is carried out through mentoring activities including the creation and training of the use of social media in product sales, grab registration, relayout, redesign menu list, as well as monitoring and evaluation. The results obtained after mentoring showed an increase in consumer access to the assisted micro businesses, as indicated by the increase in orders and turnover of the assisted micro businesses. This activity is expected to be an example for other Micro, Small and Medium Enterprises business actors affected by the COVID-19 pandemic and become a solution to the existing problems.
