Abstract

Buildings contribute more than 40% of world energy consumption, so it is feared that it will cause energy problems in the future, especially in the construction sector. One solution to reducing this problem is by analyzing energy use at the initial design stage and utilizing solar energy as one of the solar power plants (PLTS) in office buildings. To analyze the use of energy in buildings, Building Information Modeling (BIM) was used. The purpose of this research is to analyze the annual energy level of office buildings in Palembang using BIM software, namely Autodesk Revit. The number of solar panels as well as the amount of energy were also identified using web-based software (HelioScope) resulting the economic feasibility as indicated by the installation of solar panels as a component of PV mini-grid. The results showed that the use of BIM technology in analyzing building energy can provide a detailed description of the building model at the design stage. Revit analysis indicates that the building consumed electrical energy per year for about 3,647,713 kWh with a roof area of 1,657 m2. In addition, based on the HelioScope analysis, the use of renewable energy from the installation of PLTS was 152,900 kWh/year. Meanwhile, for economic feasibility analysis, the installation of PLTS in office buildings can provide a positive Net Present Value (NPV), indicating a feasible project.

Abstract

[ID] Sampah merupakan sisa kegiatan manusia yang harus dikelola dengan baik agar tidak menimbulkan permasalahan bagi kehidupan manusia atau lingkungan. Pengelolaan sampah yang tidak berbasisi 3R, minimnya armada angkutan, serta banyak terdapat tempat pembuangan sampah ilegal. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi kinerja serta mengoptimalisasi kinerja pengelolaan sampah di Kecamatan Indralaya, Kabupaten Ogan Ilir. Jumlah penduduk di Kecamatan Indralaya mencapai 20.913 jiwa pada tahun 2022. Pengukuran pengelolaan sampah meliputi aspek operasional, kelembagaan, pembiayaan, regulasi, dan partisipasi masyarakat. Pengumpulan data dilakukan dengan menyebarkan kuesioner kinerja pengelolaan sampah kepada total 100 responden di Kecamatan Indralaya, Kabupaten Ogan Ilir. Kuesioner terdiri dari 5 kategori variabel dan 18 item subvariabel. Hasil penelitian menunjukkan bahwa kinerja pengelolaan sampah dipengaruhi oleh peralatan pengangkutan dan pengolahan sampah. Keterbatasan ini sangat berpengaruh sehingga perlunya memperbanyak jumlah armada serta waktu ritasi pengangkutan dilaksakanan tidak pada jam padat kendaraan seperti pagi hari dan di sore hari. Kinerja pengelolaan sampah di Kecamatan Indralaya, Kabupaten Ogan Ilir, diperlukan strategi pengumpulan sampah berbasis 3R (Reuse Reduce Recycle) agar sampah yang ada bisa dioptimalkan dengan baik, untuk menciptakan kondisi yang strategis dan efisien. [EN] Waste is the remaining part of human activities that must be managed properly to avoid problems for human life or the environment. Waste management is not based on 3R, there is a lack of transportation fleet, and there are many illegal waste dumps. This research aims to analyze the factors that influence performance and optimize waste management performance in Indralaya District, Ogan Ilir Regency. The population in the Indralaya Sub-district reached 20,913 people in 2022. Waste management measurement includes operational, institutional, financing, regulatory, and community participation aspects. Data were collected by distributing waste management performance questionnaires to a total of 100 respondents in the Ogan Ilir District. The questionnaire consisted of 5 categories of variables and 18 sub-variable items. The results of the study showed that waste management performance was influenced by waste transportation and processing equipment. This limitation is very influential so that it is necessary to increase the number of fleets and carry out transportation routine times not during busy vehicle hours such as in the morning and in the afternoon. The performance of waste management in Indralaya District, Ogan Ilir Regency, requires a 3R (Reuse Reduce Recycle) based waste collection strategy so that existing waste can be optimized properly, to create strategic and efficient conditions.

Abstract

Integrated MSWM is still the target in most developing countries. The factors that influence MSWM performance are integrated not only from the preparation of regulations and funding, but also the preparation of the human resources involved. The planning stage of this model is inspired by the interpretation of the management process by Gunawan et al (2021) and is in line with Terry's (1972) theory which categorizes the management process into planning, organizing, implementing and controlling (POAC) functions. This research characterizes and compiles aspects and indicators of MSWM implementation which are critical issues within the framework of management functions. The goal is to make it easier to recognize the most critical aspects of MSWM implementation. The management function framework in implementing MSWM in this research was prepared using the systematic literature review (SLR) method. In developing countries, the application of MSWM still focuses on the collection system aspect which is the actuating function. In this case, an in-depth study of the planning function is needed, namely how policy and financial support influence the development of an effective technical plan for a collection system. The actuating function does not only carry out technical implementation but is also accompanied by firmness in enforcing regulations and sanctions. Regular monitoring and evaluation are needed to control the effectiveness of MSWM. Supervision requires organized human resource strength. The potential for developing an inventory of elements in each dimension is still needed. This may be caused by differences in the characteristics of the study areas.

Abstract

Abstrak Constructed wetland atau lahan basah buatan adalah salah satu penerapan eko - drainase dengan tujuan memperbaiki kualitas air, kuantitas air, konservasi air, menciptakan keindahan, dan estetika. Kondisi awal limbah greywater perumahan pada lokasi penelitian memiliki kadar limbah yang masih jauh dari baku mutu yaitu, BOD sebesar 93 Mg/L, COD sebesar 990,5 Mg/L, TSS sebesar 93 Mg/L, suhu sebesar 28,9°C dan pH air sebesar 9,6. Penelitian ini menganalisa pengaruh kerapatan tanaman eceng gondok terhadap kinerja lahan basah buatan. Pada kerapatan tanaman 13 tanaman/m2, kadar polutan turun dengan baik, untuk kadar BOD yang awalnya 990 Mg/L turun menjadi 42,17 Mg/L, kemudian kadar COD yang awalnya 794,4 menjadi 114,1 Mg/L, lalu dilihat kandungan TSS yang awalnya 93 Mg/L menjadi 20 Mg/L, dan pH dari 9,6 menjadi 7,6.  Pada kerapatan 21 tanaman/m2, untuk kadar BOD yang awalnya 990 Mg/L turun menjadi 29,73 Mg/L, kemudian kadar COD yang awalnya 794,4 menjadi 98,4 Mg/L. Kandungan TSS yang awalnya 93 Mg/L menjadi 13,6 Mg/L, dan pH dari 9,6 menjadi 7,2. Berdasarkan hasil penelitian didapatkan bahwa variasi kerapatan tanaman 13 individu/m2 menghasilkan efisiensi penurunan BOD, TSS, dan COD sebesar 94%, 79% dan 88%. Sedangkan variasi kerapatan tanaman 21 individu/m2 menghasilkan efisiensi penurunan BOD, TSS, dan COD sebesar 96%, 85% dan 90%. Kata Kunci: ekodrainase, lahan basah buatan, eceng gondok, limbah greywater  Abstract Constructed wetland or man-made wetland is one of eco-drainage applications, aiming to improve water quality, water quantity, water conservation, and for aesthetics purposes. The initial condition of greywater in the area of research does not meet the effluent standard, as such 93 Mg/L of BOD, 990,5 Mg/L of COD, 93 Mg/L of TSS, temperature of 28,9°C and pH of 9,6. This research analyze the effect of water hyacinth plant density on constructed wetland performance. At a plant density of 13 plants/m2, BOD levels which were initially 990 Mg/L decreased to 42,17 Mg/L, COD which was originally 794,4 to 114,1 Mg/L, then the TSS content was initially 93 Mg/L to 20 Mg/L, and pH from 9,6 to 7,6. For density 21 plants/m2, The initial BOD of 990 Mg/L dropped to 29,73 Mg/L, then the COD level which was originally 794,4 became 98,4 Mg/L. TSS content which was originally 93 Mg/L to 13,6 Mg/L, and pH from 9,6 to 7,2. Based on the results, plant density of 13 plant/m2 can reduce pollutant parameters up to 94% for BOD, 79% for TSS and 88% of COD while plant density of 21 plant/m2 can reduce pollutant parameters up to 96% for BOD, 85% for TSS and 90% of COD. Keywords: eco-drainage, constructed wetland, water hyacinth, greywater
