Abstract

Corrosion is a chemical phenomenon that occurs in metal materials in a wide variety of environmental conditions. always good corrosion causing losses losses that are directly or indirectly impacted. one way of corrosion prevention is the addition of corrosion inhibitors. Corrosion inhibitor is a substance that is added to the medium to prevent or reduce the rate of corrosion of metals in the environment . In this study , the authors make use of a corrosion inhibitor cocoa peel extract from the rind of the results of maceration with the variation of the cocoa peel extract concentration was 0 ppm , 500 ppm , 1000 ppm , 1500 ppm and 2000 ppm in sea water media using specimens of carbon steel pipe A53,The purpose of this study was to determine the effect of variations in the concentration of cocoa peel extract against corrosion rate and efficiency of inhibitors that occur in the carbon steel pipe A53 and analysis form macroscopic and microscopic corrosion that occurs in the specimen by using a camera and test equipment microscope with 200x magnification. From the results of this study concluded that there are significant variations in the concentration of the tea leaf extract against corrosion rate of carbon steel pipe A53. At 2000 ppm concentration variation, occurred average value of the lowest rate of corrosion inhibitor that is 0,2384 mdd and highest efficiency 83.37 %.

Abstract

Building Information Modeling (BIM) BIM adalah seperangkat teknologi, proses, kebijakan yang seluruh prosesnya berjalan secara kolaborasi dan integrasi dala sebuah model digital. BIM 3D itu disebut juga dengan model digital 3 dimensi. Banyak yang sudah mengetahui tapi kadang masih banyak orang yang salah memahaminya. Jika orang pada umumnya kenal gambar 3D itu hanya sebatas gambar yang mempunyai 3 sisi maka yang dimaksud dengan BIM 3D adalah Model 3D bangunan yang sudah berisi parameter informasi, komponen yang lebih detail dan pastinya bisa diintegrasikan ke berbagai platform dan bisa ditingkatkan ke dimensi selanjutnya. Pada pembangunan proyek Graha Pemuda Kompleks Katedral Pemuda saat ini menggunakan bim 2D yaitu autocad, pada bim 2D yaitu seperti autocad memiliki kekurangan yaitu harus menghitung volume dengan manual dan juga dalam permodelan tulangan. Pada bim 3D dapat menampilkan permodelan keseluruhan gedung dan juga memudahkan menghitung volume suatu bangunan gedung. Penelitian ini diharapkan dapat bermanfaat untuk memudahkan menghitung volume bangunan gedung dan mempermudah memahami gambar perancangan. Pada penelitian ini peneliti dalam pengumpulan datanya menggunakan metode kuantitatif. Dari hasil pemodelan yang telah dilakukan dengan menggunakan konsep Building Information Modeling (BIM) menjadi lebih efektif dan efisien dikarenakan semua informasi seperti elemen struktur dapat dimodelkan dengan lebih cepat, akurat, rinci seperti pemodelan tulangan sebuah struktur dan juga dapat mengetahui tabrakan elemen struktur dengan elemen MEP. Konsep BIM juga dapat menampilkan perhitungan dan analisis volume struktur.

Abstract

This study aims to understand the perceptions of fishermen towards the regulated fishing policy implemented by the Indonesian government. This policy is an effort to maintain the sustainability of fishery resources and marine ecosystems. The research method used is a quantitative survey with a descriptive approach, conducted on fishermen in the Sorong Manoi District, West Papua. Data were collected through questionnaires, structured interviews, and field observations, with a sample of 72 fishermen. The results of the study show that most fishermen have a positive understanding of this policy, recognizing its benefits in maintaining the sustainability of fish resources and reducing conflicts among fishermen. However, there are concerns related to the short-term economic impact and the need for more effective socialization and technical assistance. Fishermen also realize the importance of maintaining the marine ecosystem and support the use of environmentally friendly fishing gear.

Abstract

Keselamatan dan Kesehatan Kerja (K3) merupakan aspek krusial dalam industri minyak dan gas, terutama di lingkungan kerja yang memiliki potensi risiko tinggi seperti kilang minyak. Penelitian ini bertujuan untuk menganalisis implementasi sistem K3 di area kilang utilitas PPSDM Migas Cepu, dengan fokus pada pengelolaan risiko kerja, penerapan standar keselamatan, dan dampak terhadap lingkungan. Metode yang digunakan dalam penelitian ini meliputi observasi langsung di unit kilang utilitas, wawancara dengan bagian K3, serta studi literatur terkait peraturan keselamatan industri. Hasil penelitian menunjukkan bahwa PPSDM Migas Cepu telah menerapkan sistem manajemen K3 berbasis ISO 45001, dengan berbagai langkah mitigasi bahaya, termasuk penggunaan alat pelindung diri (APD), inspeksi rutin, penerapan sistem izin kerja, serta pengelolaan limbah industri. Selain itu, PPSDM Migas juga memiliki fasilitas kesehatan yang mendukung keselamatan tenaga kerja, seperti poliklinik dan program pemeriksaan kesehatan berkala. Pengukuran kebisingan, kualitas udara, serta pencahayaan juga dilakukan untuk menjaga lingkungan kerja yang aman. Dalam proses produksi, potensi bahaya seperti ledakan, kebocoran gas, dan kecelakaan mekanis telah diantisipasi melalui penerapan teknologi keselamatan, seperti sistem Burner Management pada furnace dan pemantauan kondisi peralatan secara berkala. Implementasi yang baik dalam sistem K3 ini diharapkan dapat mengurangi risiko kecelakaan kerja, meningkatkan efisiensi operasional, serta menjaga keberlanjutan lingkungan industri.

Abstract

Penyelenggaraan Perizinan Berusaha Berbasis Risiko melalui Sistem Online Single Submission (OSS) merupakan pelaksanaan Undang-Undang Nomor 11 Tahun 2020 Tentang Cipta Kerja. OSS Berbasis Risiko wajib digunakan oleh Pelaku Usaha, Kementerian/Lembaga, Pemerintah Daerah, Administrator Kawasan Ekonomi Khusus (KEK), dan Badan Pengusahaan Kawasan Perdagangan Bebas Pelabuhan Bebas (KPBPB). Kementerian Perdagangan memanfaatkan banyak sistem informasi yang secara bisnis proses saling berkaitan antara satu layanan dengan layanan lainnya, namun sistem informasi tersebut masih terpisah-pisah sehingga sulit untuk memperoleh kesatuan informasi terkait pelaku usaha perdagangan. Penelitian ini berhasil marancang Sistem Profiling Pelaku Usaha (SPPU) dengan menggunakan metode Spiral Model untuk membantu pimpinan dalam menentukan kebijakan yang tepat guna dengan fitur-fitur Perusahaan OSS, Eksportir, Buyer, Distribution Dashboard, Distribution Receive NIB, Distribution Receive License, Distribution Receive File DS, Check API NIB, Check API NPWP, dan Manajemen User. Pengujian SPPU dengan metode blackbox testing diperoleh hasil bahwa seluruh rancangan fitur dapat berjalan dengan baik.

The platform also supports the flexibility of the learning process, providing a platform for learners to learn independently and collaboratively. Data analysis showed a significant increase in learners' engagement during the learning process. ABSTRAK Pada era modern, pendidikan dituntut untuk mengintegrasikan teknologi dalam proses pembelajaran guna menyesuaikan diri dengan perkembangan zaman. Penggunaan teknologi dapat meningkatkan keterlibatan peserta didik melalui metode yang lebih interaktif dan menarik, serta memperkuat efektivitas dalam penyampaian materi. Dengan demikian, integrasi teknologi menjadi langkah penting untuk menciptakan pembelajaran yang relevan dan berkualitas. Penelitian ini bertujuan untuk mendeskripsiskan penerapan platform digital sekolahku sebagai media pembelajaran teks novel di SMA Al Hikmah Surabaya. Dengan menggunakan metode deskriptif kualitatif, penelitian ini melibatkan peserta didik kelas XII dan guru Bahasa Indonesia sebagai sumber data. Teknik pengumulan data dilakukan melalui observasi, wawancara, dan dokumentasi. Hasil penelitian yang didapatkan menunjukkan bahwa sekolahku memberikan bentuk pengemasan materi pembelajaran yang menarik melalui integrasi konten multimedia, adanya asesmen formatif, serta fitur interaktif yang dapat meningkatkan motivasi dan pemahaman peserta didik terhadap teks novel. Platform ini juga mendukung fleksibilitas proses pembelajaran, memberikan wadah peserta didik untuk belajar secara mandiri maupun kolaboratif. Analisis data menunjukkan peningkatan signifikan dalam keterlibatan peserta didik selama proses pembelajaran berlangsung.
