Perhatian pada sektor air bersih semakin meningkat secara signifikan. Pada World Summit on Sustainable Development (WSSD) di Johanesburg, 2-4 September 2002, air bersih menjadi salah satu perhatian dari lima sektor yang dibahas, yaitu water, energy, health, agriculture, dan biodiversity (disingkat sebagai WEHAB). Air bersih memiliki tingkat kepentingan yang tinggi dalam perkembangan aspek ekonomi, sosial, dan lingkungan. Banyak upaya dilakukan untuk menjaga pasokan air, termasuk penghematan air, waste water management, dan rain water harvesting (RWH). Pada penelitian ini, dilakukan analisis terhadap perancangan sistem RWH pada bangunan publik dengan studi kasus Hotel Novotel Yogyakarta. Kegiatan utamanya yaitu melakukan studi kelayakan pada existing building condition dan menganalisis potensi penghematan dengan pemanfaatan sistem RWH.Air hujan yang biasanya langsung dibuang ke saluran drainase kota dikumpulkan, kemudian diberikan pengolahan agar sesuai dengan standar kualitas air minum yang dikembangkan oleh World Health Organization (WHO) sehingga dapat dimanfaatkan sebagai sumber air bersih pada hotel. Selain itu, perancangan sistem RWH ini juga mengacu pada Greenship Rating Tools yang dikeluarkan oleh GBCI (Green Building Council Indonesia). Dari perhitungan yang dilakukan, rata-rata air hujan yang dapat ditampung dalam satu bulan yaitu 478.820 liter dan dalam satu tahun dapat terkumpul sebesar 5.745.809 liter. Pada musim hujan, air hujan pada Hotel Novotel dapat memasok hingga 21% dari total kebutuhan air bersih dalam satu bulan. Rata-rata konsumsi air yang dapat ditangani oleh air hujan dalam setahun adalah 8,6%.

Sektor bangunan berperan secara signifikan pada konsumsi energi nasional. Pada bidang pencahayaan, umumnya sebuah bangunan komersial biasanya menghasilkan beban 20% - 45% dari konsumsi energi total yang dibutuhkan dari gedung tersebut (UNEP, 2006). Untuk memaksimalkan pemanfaatan beban energi yang sebesar itu, sistem pencahayaan harus memperhatikan faktor performansi dan kenyamanan visual yang dihasilkan. Penelitian ini dilakukan untuk menganalisis kualitas sistem pencahayaan pada dengan studi kasus Hotel Novotel Yogyakarta pada ruang pertemuan dan lobi dengan tiga metode, yaitu dengan perhitungan numeris dengan dasar acuan studi Standar Nasional Indonesia (SNI) tentang pencahayaan, metode pengukuran langsung, dan simulasi komputer dengan menggunakan DIALux. Berdasarkan hasil penelitian, nilai iluminansi rata-rata ruang pertemuan dengan perhitungan numeris 78,1 lux, pengukuran langsung 72,33 lux, dan simulasi 89 lux dengan nilai baku mutu SNI 300 lux. Nilai iluminansi rata-rata lobi pada malam hari dengan perhitungan numeris yaitu 49,05 lux, pengukuran langsung 48,02 lux, dan simulasi 70 lux dengan nilai baku mutu SNI 100 lux. Berdasarkan data tersebut diketahui bahwa nilai iluminansi rata-rata ruang pertemuan dan lobi pada malam hari belum berhasil memenuhi standar kenyamanan SNI. Nilai iluminansi rata-rata lobi pada siang hari yaitu dengan perhitungan numeris 151,3 lux, pengukuran langsung 91,37 lux, dan simulasi 222 lux. Hal ini berarti lobi pada siang hari berhasil mendekati standar kenyamanan SNI. Analisis perbandingan ketiga metode tersebut menunjukkan bahwa perhitungan numeris dengan dasar SNI dilakukan sebagai dasar dari perancangan sistem pencahayaan, simulasi dilakukan untuk memperoleh perhitungan yang optimal, dan evaluasi sistem pencahayaan dilakukan dengan pengukuran langsung di lapangan.

Abstract: The density of major cities in Indonesia is the impact of the rapid development of the population. Increasing the population as well as their welfare make the residential and traffic environment in urban areas less healthy. Noisy, and air quality as the main indicators that can be felt to be very disturbing to the human environment. The sound quality perspective is one that is overlooked. Even though the government of the Republic of Indonesia has issued standard noise levels in Kep-48 / MENLH / 11/1996, evaluation and control of reality in the field is still lacking. The soundscape approach that is very concerned about the environment as a resource will be the most effective when applied in urban and regional planning. This paper aims to explore how sound impacts in providing an auditory experience in open space through a soundscape approach with case studies of open space or the court of the Great Mosque of Yogyakarta. This case can be an example of implementing a strategy to create peace of space in the midst of the hustle and bustle of the city. On the other hand soundscaping techniques become the needs of every city to do, and in particular there must be a spatial pattern that unites and adapts to each other between buildings, open spaces, vegetation, water elements and activities, so that the sustainability of a comfortable and calm space will last long. Keywords: space sustainability; noise; auditory experience; soundscapeAbstrak: Kepadatan kota-kota besar di Indonesia merupakan dampak perkembangan penduduk yang begitu cepat meningkat. Peningkatan jumlah penduduk sekaligus kesejahteraan mereka membuat lingkungan pemukiman dan lalu lintas di perkotaan semakin kurang sehat. Bising, dan kualitas udara sebagai indikator utama yang dapat dirasakan sangat mengganggu lingkungan hidup manusia. Perspektif kualitas suara adalah salah satu yang terabaikan. Sekalipun pemerintah Republik Indonesa sudah mengeluarkan baku tingkat kebisingan dalam Kep-48/MENLH/11/1996, namun evaluasi dan kontrol terhadap kenyataan di lapangan masih kurang dilakukan. Pendekatan soundscape yang sangat memperhatikan lingkungan sebagai sumber daya akan menjadi yang paling efektif bila diterapkan dalam perencanaan kota dan kawasan. Tulisan ini bertujuan untuk mengeksplorasi bagaimana dampak suara dalam memberikan pengalaman auditory dalam ruang terbuka melalui pendekatan soundscape dengan studi kasus kawasan ruang terbuka atau pelataran Masjid Agung Yogyakarta. Kasus ini dapat menjadi contoh penerapan strategi menciptakan ketenangan ruang di tengah hiruk pikuk kota. Di sisi lain teknik soundscaping menjadi kebutuhan setiap kota untuk dilakukan, dan secara khusus harus ada pola spasial yang menyatukan dan saling menyesuaikan antara bangunan, ruang terbuka, vegetasi, unsur air dan aktifitas, sehingga keberlanjutan ruang kawasan yang terkondisi nyaman dan tenang akan bisa bertahan lama.Kata Kunci: keberlanjutan ruang; kebisingan; pengalaman auditory; soundscape

Electricity consumption in the household sector is classified into two categories based on the economic class of the household. The first category is the low class, in which the greatest electricity consumption (approximately 20.00%) is used for lighting. The second category is the medium and high class, in which the greatest electricity consumption (approximately 20.00-32.00%) occurs for powering the air conditioning (AC) system. To date, vertical type housing can be commonly found in the medium class, and as of 2017, the level of occupation has reached 9.52%. This condition calls for an analysis on the energy consumption and energy efficiency of the buildings. Case found in a low-cost apartment building, also known as Rumah Susun Sederhana Sewa (Rusunawa) in Yogyakarta, Indonesia, is one example where an energy monitoring system is needed. This is due to the inhabitants' habit of electrical usage that is unsuitable to the Rusunawa's function, such as their inefficient use of AC and washing machines. The energy meter system measures the electrical voltage and current of electrical appliances that are attached to the system. This system utilizes a ZMPT101B-5 sensor to measure the voltage and an ACS712 sensor to measure the elctrical current. The design of the energy meter system enables one to measure the voltage and current of electrical appliances with a 4.40% margin of error. Based on the measurements obtained in this paper, the AC is the greatest source of power consumption, with an approximate value of 800 kWh.

Like other developing countries where traffic is a significant sound nuisance, traffic in Indonesian urban areas is boisterous. How this condition is regulated by the Indonesian government so that the community can live healthily and comfortably is a very crucial issue. Unfortunately, Indonesia has not had any sound environmental improvement since the regulation was enacted. Additionally, regulators and government officers who run the rule carelessly worsen the condition. This study aims to study how sound is regulated in Indonesia’s central and local governments, what types of sound or noise and levels are covered, and whether recent local regulations have been enacted to regulate sound in Indonesian cities. The study mainly uses quantitative, i.e., snowball or chain referral sampling techniques, to collect sound regulations applied in ten large and busy cities in Indonesia. Then, the qualitative stage was conducted based on the content of the rules. The data shows that the Indonesian government at both the central and regional levels does not have legal standing to regulate noise caused by the absence of noise regulation at the statutory level that can force those who violate the law to be punished. The only regulation is by the Minister of Environment, dated 1996, which is referenced nationally and adopted by most cities without or with minor modifications. This study found that (1) six of the ten cities regulate only one type of noise among various types of noise, (2) twelve of the 35 local regulations incorporate noise regulations into air pollution regulations instead of stand-alone regulations, (3) because provinces and cities adopt central regulations, the lowest noise level follows the central standard at 55 dB for settlement area without specific frequency ranges, (4) there is no straightforward procedure on how measurements to be carried out except in regulations stipulated by Yogyakarta province. There is also a fact that a standardized procedure for measuring noise is vital to be included in the regulation because unskilled government officials collected invalid data in dealing with a noise complaint leading to an unresolved situation.

Open-plan offices have become widely adopted in various industries as a workplace environment. However, this office layout type suffers from speech privacy, which can be represented by the acoustic parameter known as the Speech Transmission Index (STI). ISO 3382-3:2012 provides guidelines for calculating the acoustic parameters of a room tailored explicitly for open-plan offices. However, the existing method in ISO 3382-3:2012 requires a parallel layout of workstations to determine the STI value, which is hardly found in modern office settings. This study presents a technique to predict the ideal values of rP and rD, based on the relationship between %Alcons and the Speech Transmission Index (STI) for a specific workstation, using linear regression and in-situ measurements. The analysis of acoustic conditions in an open-plan office reveals that modified techniques can predict the acoustic quality in a modern office layout. The D2, S values indicate good acoustic quality, but the Lp, A, S,4m values do not meet the required standard. Using %Alcons equations, the study shows how to predict distraction distances and categorize workstations as 'Distracted' or 'Not distracted'. The results indicate only a small percentage of workstations allow for private communication.

Introduction: Ship-to-shore (STS) crane operators strive for efficiency in their work, but they must take a hard look at their high-risk jobs. It is necessary to learn how to improve occupational safety and health. This study aims to investigate the problems faced by STS crane operators working in container ports and to understand the importance of fit-for-work monitoring procedures, particularly for individuals working in high-risk industries such as STS operators. Methods: This study used a qualitative approach, and data were collected through interviews and observations of STS operators and in-house clinic staff. Nine STS operators, two in-house clinic staff, and two safety, health, and environment (SHE) staff were interviewed. Results: This study found that container terminal companies emphasise two critical aspects for STS operators: productivity and occupational safety and health. STS operators face health problems, including physical and psychological problems, due to the fast-paced work system, sleep patterns, daily activities, and thoughts that are difficult to control. Employees have coping mechanisms to deal with fatigue, and stakeholders have effectively communicated the company's safety and health culture. Most stakeholders in a container terminal company want a fit-for-work monitoring system to make the business efficient and sustainable. Conclusion: The STS industry faces a significant problem with operator fatigue, which can negatively impact safety and productivity. This issue requires a comprehensive strategy, including legislation to regulate working hours and shift patterns, technology to combat fatigue, and operator education and training.
