Abstract

Dalam menumbuhkan tingkat kepekaan mengenali tekstur benda pada anak diperlukan suatu metode yang tepat agar dapat lebih memberikan rangsangan mengenai berbagai macam bentuk dan warna benda disekitar. Cara yang dapat dilakukan yaitu menggunakan media pasir ajaib (magic sand), bermain cat air, dan lilin mainan. Hal ini bertujuan untuk mengkaji upaya peningkatan kepekaan anak untuk mengenal tekstur benda disekelilingnya dengan mengelola permainan sensorik pada anak usia dini di PAUD Tumbuh Harapan Desa Karanganyar Kecamatan Kalibening.

Abstract

This paper is prepared as one of the requirements for completing studies in the field of Civil Engineering. The topic we discuss in this paper is the Occupational Safety and Health (K3) Budget for Construction in accordance with the Omnibus Law. Our objective is to gain a comprehensive understanding of the Construction K3 Budget that aligns with the Omnibus Law in Indonesia and to analyze its impact on the construction industry in the country. The background of this topic is crucial considering the importance of understanding and implementing Occupational Safety and Health (K3) in the construction industry in Indonesia. With the changing times and technological advancements, K3 has become a critical aspect of carrying out construction activities. Therefore, we find it essential to explore and deepen our understanding of the K3 Budget to provide a comprehensive understanding to the readers. In this paper, we will delve into the K3 Budget and the laws regulating it. We will elaborate on the concepts, theories, and principles related to Construction K3. Additionally, we will involve analysis and a review of relevant literature to support our understanding and arguments. We hope that this paper can be beneficial and make a meaningful contribution to both the professional and academic realms. We also aspire for this paper to serve as a useful reference for readers interested in further studying the Construction K3 Budget. In conclusion, we express our gratitude to all those who have assisted and supported us in preparing this paper. Without their help and support, this paper would not have come to fruition. We hope that this paper proves to be useful and provides valuable insights to the readers.

Abstract

Penelitian ini bertujuan untuk menganalisis tingkat kebisingan pada unit kilang minyak di PT. X Cepu berdasarkan baku mutu lingkungan dan nilai ambang batas kebisingan kerja. Metode yang digunakan meliputi observasi lapangan dan pengukuran langsung dengan alat Sound Level Meter pada lima titik pengukuran di unit furnace dan pompa crude oil selama dua hari. Hasil pengukuran menunjukkan bahwa sebagian besar titik melebihi baku mutu kawasan industri (70 dB(A)), dan satu titik melebihi ambang batas kerja (85 dB(A)). Tingkat kebisingan tertinggi tercatat sebesar 89,5 dB(A) di titik depan furnace. Studi ini menyimpulkan bahwa paparan kebisingan dapat berisiko terhadap kesehatan kerja meskipun pekerja menggunakan alat pelindung diri. Diperlukan pengendalian kebisingan yang lebih lanjut untuk menjamin keselamatan pekerja.

Abstract

This study aims to explore the potential of marble industry waste as a contextual chemistry learning medium that supports environmentally friendly learning practices in a high school located in a marble-producing area. The research uses a descriptive qualitative method to investigate how marble waste, particularly in the form of calcium carbonate powder, can be utilized in chemistry learning to minimize the use of hazardous chemicals and reduce laboratory waste. Data were collected through field observations at local marble industries, interviews with industry workers and chemistry teachers, and documentation of the marble processing stages and waste materials. The data were analyzed using a descriptive technique to interpret the findings based on real conditions in the field. The results show that marble waste has significant potential to be used in simple chemistry experiments such as acid-base reactions, identification of chemical compounds, and the study of geological processes. The use of locally sourced waste materials enhances students' understanding of chemistry concepts, increases learning motivation, and contributes to a safer and more sustainable school laboratory environment. The findings suggest that local industrial materials can be integrated effectively into science education to create meaningful and environmentally responsible learning experiences.

Abstract

Pengolahan sampah anorganik dapat dilakukan dengan berbagai cara, salah satunya adalah dengan proses pyrolysis. Proses pyrolysis pada penelitian ini dikerjakan dengan memvariasikan laju pemanasan dan suhu reactor. Dengan tujuan untuk mengetahui kuantitas dan karakteristik hasil dari proses pyrolysis.Dari penelitian yang telah dilakukan, didapatkan hasil bahwa kuantitas minyak hasil pyrolysis pada laju pemanasan 6,94oC/menit dengan suhu reactor 0oC – 250oC selama 36 menit sebanyak 118 mL berwarna hitam pekat dengan nilai viskositas 0,3 dPa.S, densitas 780 kg, dan flash point 34oC. Pada laju pemanasan 1,66oC/menit dengan suhu reaktor 250oC – 300oC selama 30 menit menghasilkan 130 mL berwarna kuning tua dengan nilai viskositas 0,29 dPa.S, densitas 770 kg, dan flash point 33oC. Selanjutnya pada laju pemanasan 1,78oC/menit dengan suhu reactor 300oC – 350oC selama 28 menit menghasilkan 165 mL berwarna kuning jernihdengan nilai viskositas 0,28 dPa.S, densitas 760 kg, dan flash point 32oC. Pada laju pemanasan 2,38oC/menit dengan suhu reaktor 350oC – 400oC selama 21 menit menghasilkan 180 mL berwarna kuning kecokelatan dengan nilai viskositas 0,31 dPa.S, densitas 780 kg, dan flash point 34oC. Dan pada laju pemanasan 2,77oC/menit dengan suhu reactor 400oC – 450oC selama 18 menit menghasilkan sebanyak 201 mL berwarna abu-abu keruh dengan nilai viskositas 0,33 dPa.S, densitas 790 kg, dan flash point 35oC.
