Reputation loss of a pipeline failure subject to corrosion is commonly neglected due to its qualitative nature. However, case studies found that perceptions of the stakeholders are prone to affect pipeline owner’s long-term reputation. Identifying the influence factors is insufficient to assist the owner to respond if pipeline failure occurs. Thus, this article endeavors to prioritize the influential reputation loss factors by interviewing six experts of pipeline integrity management personnel. The analytic hierarchy process multi-criteria decision making method was selected to help the prioritization process. Result shows that the most influenced factor is the loss of customer confidence (B1) and employee(s) caused accident (C9) ranked the least. The effort to quantify reputation loss can be substituted by prioritizing them according to stakeholders’ preferences as an initial step to monetarily quantify these factors in future. Thus, a comprehensive pipeline risk assessment and the pipeline integrity management can be achieved and simultaneously improve the company’s annual profit margin.

Street children as a reality that can be found in every city in Indonesia becomes a "magnet" of urban issues especially in education sector. Marginal Theory assumes that urban poverty occurs due to culture of poverty that is isolated within certain societies with apathetic and pessimist individual characters and unsupportive family and community environments. The existence of marginalized groups became the main source of the occurrence of various forms of public illness, one of them is street children. Mobile Architecture is a reaction from the world of architecture in presenting new solutions in the social world. The phenomenon of formal education that is always seen with the size of formalities and measurable values, it should be seen from the other side that presents a reaction to the world of architecture as a container. The main question is how the concept of architectural flexibility can work optimally in the existence of this street children's school design? So that can be according to time, function and place. Architectural flexibility as the concept offered is accordance with current social and environmental conditions. This flexibility is supported by Portable Architecture and Folding Architecture methods so that a design - in this case street children’s school - can match the space at any time. This method allows to environment changes and can reach street children scattered at some point in the city. Based on the characteristics of street children who have demands on the street to make money, the empowerment approach proposed is the "Street Based Intervention" approach. This approach makes street children will be approached at a certain point then accommodated and given services in the form of education, coaching, and the place of play and socializing

Instalasi pengolahan air limbah (IPAL) industri tapioka di Kabupaten Lampung Timur Provinsi Lampung menggunakan kombinasi UASB dan tangki aerasi. Air limbah kemudian diolah lebih lanjut pada kolam stabilisasi. Pada saat ini seluruh kolam stabilisasi tidak menggunakan pelapis membran ataupun tanah lempung. Hal ini dinilai mencemari air tanah di daerah sekitar pabrik. Air limbah yang dilepas ke badan air juga masih melebihi baku mutu. Sehingga perlu dilakukan evaluasi unit bangunan eksisting dan memberikan solusi atas hasil evaluasi ini. Evaluasi dilakukan dengan melakukan komparasi kondisi eksisting dengan kriteria desain unit IPAL. Hasil study menunjukan bahwa beberapa kriteria seperti waktu detensi, organic loading rate, velocity, dan dimensi pada beberapa unit tidak sesuai. Solusi yang diberikan atas pencemaran air tanah adalah penutupan kolam stabilisasi dan menggantinya dengan kombinasi unit anaeobic baffled reactor (ABR) - facultative pond. Instalasi tersebut dinilai mudah dan murah dalam pengoperasian dan perawatan. Data kualitas dan kuantitas air limbah didapat dari kombinasi data primer dan sekunder. Data yang didapat dijadikan acuan untuk perencanaan detail engineering design IPAL pengganti kolam stabilisasi. Perhitungan biaya untuk IPAL dan perpipaan mengacu pada Standar Nasional Indonesia dan Harga Satuan Pokok Kerja (HSPK) Kota Bandar Lampung. Setelah dilakukan perhitungan terhadap biaya pembangunan ABR dan kolam fakultatif, diperlukan biaya sebesar Rp. 761.313.124.
