Abstract

This paper presents the building monitoring system that can determine the building condition in real time and ensure the safety of building operations. This monitoring building system can detect the ambient, CO gas, fan, water leak, and also intrusion detectors, through a wired sensor network. Then the data is processed by a main controller to generate a report that sent to the inspectors through ZigBee and / or sound an alarm if the situation is considered dangerous. Prototype of this monitoring system shows precision and stability with minimal error rate. Main controller can receive data from the sensor network properly and send it through ZigBee modules.

Abstract

ABSTRACT. Limitations in obtaining energy is one of the problems that occur throughout the world, including in Indonesia. One alternative that can be used to overcome the scarcity of raw materials is to use energy from biomass. The purpose of this study was to determine the effect of a mixture of alaban charcoal powder (Vitex pubescens) and palm shell charcoal (Elaeis guineensis Jacq ) on the quality of charcoal briquettes. The research will be conducted using a completely randomized design (CRD). The conclusion obtained from the results of this study, the results obtained from the test that the density in all treatments with an average value ranging from 1.1676-1.5392 g/cm3 meets the briquette standard in Indonesia (SNI 01-6235-2000) , namely ≥ 0.44 g/cm3, the water content in all treatments with an average value ranging from 3.4433-6.3433% complies with the briquette standard in Indonesia (SNI 01-6235-2000), namely ≤8% , the ash content in all treatments with an average value ranging from 0.5400-6.7500% complied with the standards of briquettes in Indonesia (SNI 01-6235-2000), namely ≤8%, volatile matter in all treatments with an average value -average ranges from 18.4967-25.9733%, only close to standard briquettes in Indonesia (SNI 01-6235-2000), namely <15%, carbon is bonded to all treatments with average values ranging from 67.7700-74.9600 % is only close to the standard of briquettes.

Keterbatasan dalam memperoleh suatu energi merupakan salah satu permasalahan yang terjadi di seluruh dunia tidak terkecuali di Negara Indonesia. Salah satu alternatif yang dapat digunakan untuk mengatasi kelangkaan bahan baku adalah dengan menggunakan energi dari biomassa. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh variasi campuran serbuk arang alaban (Vitex pubescens) dan arang tempurung kelapa sawit (Elaeis guineensis Jacq ) terhadap kualitas briket arang. Penelitian yang akan dilakukan menggunakan metode Rancangan Acak Lengkap (RAL). Kesimpulan yang diperoleh dari hasil penelitian ini, Hasil yang diperoleh dari pengujian bahwa kerapatan pada semua perlakuan dengan nilai rata-rata yang berkisar antara 1,1676-1,5392 g/cm3 telah memenuhi standar briket di Indonesia (SNI 01-6235-2000), yaitu ≥ 0,44 g/cm3, kadar air pada semua perlakuan dengan nilai rata-rata yang berkisar antara 3,4433-6,3433%telah memenuhi standar briket di Indonesia (SNI 01-6235-2000), yaitu ≤8%, kadar abu pada semua perlakuan dengan nilai rata-rata yang berkisar antara 0,5400-6,7500%  telah memenuhi standar briket di Indonesia (SNI 01-6235-2000), yaitu ≤8%, zat terbang pada semua perlakuan dengan nilai rata-rata berkisar antara 18,4967-25,9733% hanya mendekati standar briket di Indonesia (SNI 01-6235-2000), yaitu <15%, karbon terikat semua perlakuan dengan nilai rata-rata berkisar antara 67,7700-74,9600% hanya mendekati standar briket di Indonesia (SNI 01-6235-2000), yaitu  (≥77%), dan nilai kalor pada semua perlakuan dengan nilai rata-rata berkisar antara 5289,5133-6616,2267 telah memenuhi standar briket di Indonesia (SNI 01-6235-2000), yaitu (≥5000).

Abstract

During their productive years, athletes can earn incomes above the per capita average of a country or region. However, upon retirement, athletes often face financial problems, as many professional athletes lack the skills to effectively manage personal finances. Their occupation, which heavily relies on physical strength, makes their finances vulnerable. Additionally, professional athletes are prone to mental health issues and excessive anxiety or depression. Some athletes even commit suicide after retiring. The presence of these risks forces many athletes to retire at a relatively young age, around their 30s, and they may struggle to find suitable post- athletic careers. Hence, athletes need to plan their finances for a longer period compared to most people. Unstable incomes during their sports careers, often dependent on sponsorships, prizes, and awards, make them vulnerable to income declines after retirement. Moreover, high expenses during their careers, especially for training and medical care, might not have allowed them to build substantial savings. Researchers argue that financial literacy and security enable athletes to ensure their financial well-being, particularly in their post-athletic lives. Financial literacy can help athletes achieve sustainable financial well-being. Financial planning before retirement is crucial for individuals or families to achieve stable and prosperous financial conditions. Interviews we conducted found that all athletes at Dojo Judo Gajah Mungkur have goals for the money earned from competitions. However, only a few, especially the younger ones, use their income productively. This is evidenced by initial interviews showing that most of them, or 50-70 percent, spend their income on purchasing motor vehicles, and 80 percent of athletes do not have businesses or investments (both in the real and non-real sectors) that can generate additional income outside their profession.
