BIPV is an integral part of the building envelope such as the roof or the facade. There is a difference of Building Integrated Photovoltaic placement between the location in the equator region and other regions. The study aims to know the effect of BIPV placement and its potency in generating electrical energy. The study reviews previous research related topics of BIPV in all regions. The study shows that BIPV placement is determined by the sunâ€™s position that producers incidence angle. Incidence angle should fall perpendicularly on a surface to obtain the high of an intensity of solar irradiation. Therefore, most of BIPV placement in the equator region are on rooftops while in the regions far from equator not only on rooftops but also on facades. Roofs are so far considered to be the ideal location for BIPV placement since roofs provide the best solar energy generation. The potency of BIPV can be explored in building design with the variation of orientation and shape to increase the building surfaces for getting solar potential.

One of the most important parts of a project management is the quality management. While it is absolutely necessary to conduct a thorough research on the maturity of quality management in construction companies, especially contractors so that construction companies know at what level of their company quality, this has an effect on building customer perceptions of their companies and the business of the company itself to continue to grow to be able to reach the highest maturity level. This paper aims to propose an assessment model of contractor quality management maturity (QMM) that covers both the corporate and project levels of a construction project. Determination of research variables was conducted with the study of literature in depth and validated by experts. Weighting variables by pairwise comparison method were based on interviews with experts and was represented in the form of a spider web. For model validation, case studies of large state-owned contractors and a medium-sized private contractor in Surabaya were used. The weighting for QMM assessment on contractors is 43% on corporate level and 57% on project level. In corporate level there are 10 variables with each weighting: People and Customer Management (2.9%), Supplier Partnership (1.6%), Communication of Improvement Information (2.4%), Customer Satisfaction Orientation (5.3%), External Interface Management (1.4%), Strategic Quality Management (6.2%), Team Work Structures for Improvement (4.3%), Operational Quality Planning (4.4%), Quality Improvement Measurement System (8.2%), and Corporate Quality Culture (6.3%). Project level quality consists of 39% for product quality and 18% for service quality. In the project level there are 8 variables for product quality: Performance (9.0%), Features (4.1%), Reliability (8.0%), Conformance (5.6%), Durability (4.5%), Serviceability (3.0%), Aesthetics (1.7%), Perceived Quality (3.1%). While the service quality consists of 5 variables: Service Reliability (4.9%), Responsiveness (2.7%), Assurance (5.7%), Emphaty (1.8%), and Tangibles (2.8%).

Contact angle measurement is a technique which can be used to determine the surface properties of a substance and observe the interaction of surfaces. When polar liquid dropped on a non-polar solid, it will make an interaction that can observed from the contact angle. In simple way, the different polarity of the solid and the liquid sample will affect to the contact angle obtained. In this work the value of contact angle will be correlated to the polarity of the sample. The results showed that the plot between polarity parameter with contact angle on polytetrafluoroethylene substrat has a correlation which formed a sigmoidal curve with R2=0,954. It means the polarity of liquids can be determined by the contact angle values.

Prinsip pembangunan berkeadilan sosial mengindikasikan pentingnya dilaksanakannya pembangunan secara menyeluruh, baik di area perkotaan ataupun daerah pedesaan. Area pedesaan seringkali tertinggal di bidang pendidikan dan pembangunan dikarenakan faktor geografis yang seringkali menghambat masuknya fasilitas dan modernisasi ke area pedesaan. Salah satu pembangunan yang seharusnya mendapat perhatian adalah perkembangan pendidikan di pedesaan. Seringkali siswa di desa tertinggal dalam hal pendidikan dibandingkan dengan siswa di perkotaan. Hal ini dikhawatirkan menimbulkan kesenjangan pendidikan yang dapat menghambat pembangunan. Salah satu cara mengatasinya adalah dengan mengembangkan profesionalisme guru di area pedesaan yang pada akhirnya diharapkan dapat meningkatkan prestasi/kualitas pendidikan siswa di desa. Beberapa metode yang dapat dilaksanakan adalah dengan membentuk komunitas belajar guru sebagai sarana dan media guru untuk bersama-sama belajar dalam struktur komunitas yang lebih bersifat horizontal dan diadaptasikan dalam konteks sosial dan budaya area pedesaan yang bersifat kolektif. Komunitas belajar ini diharapkan lebih efektif untuk mengembangkan kualitas pendidikan dan pengetahuan guru karena lebih bersifat komunitas berkala serta menstimulasi diskusi dan kegiatan kegiatan akademis yang didasarkan pada isu-isu pendidikan yang kekinian dan sesuai dengan konteks sosial dan budaya. Metode yang kedua yaitu dengan melalui pembentukan kepemimpinan sekolah yang bersifat transformasional. Kepemimpinan tersebut diharapkan dapat menstimulasi perubahan/perkembangan dan dapat memberikan iklim yang kondusif untuk tumbuh kembangnya kepemimpinan guru. Model kepemimpinan transformasional dapat beradaptasi dan menerima perubahan-perubahan yang terjadi dengan cepat didunia pendidikan sebagai dampak globalisasi dan perkembangan ilmu pengetahuan dan teknologi. Melalui kepemimpinan transformasional, diharapkan guru dapat terpacu untuk selalu mengikuti perubahan dan perkembangan pengetahuan dan metode pembelajaran.

Upaya peningkatan pemanfaatan bahan bakar gas bumi untuk rumah tangga dan pelanggan kecil terhambat karena terbatasnya infrastruktur yang menghubungkan gas bumi dari sumbernya ke konsumen. Kegiatan survei dan pemetaan ini sangat diperlukan karena akan memberikan gambaran eksisting lokasi rencana jalur jaringan gas bumi. Dengan demikian kegiatan perencanaan akan lebih realistis, efektif dan efesien karena memperoleh informasi eksisting kondisi di lapangan sehingga dalam pelaksanaannya nanti tidak mengalami kendala yang berarti. Kegiatan survey dan pemetaan dalam rangka perencanaan jaringan gas rumah tangga ini dilakukan dengan dua metode yaitu, terrestrial dan fotogrammetri jarak dekat. Metode terrestrial digunakan untuk memberikan gambaran potongan memanjang dan melintang sepanjang jalur rencana pipa gas sedangkan fotogrammetri jarak dekat digunakan untuk memberikan gambaran tampak dari udara mengenai lokasi perencanaan jaringan pipa gas serta perkiraan sebaran pelayannya. Dari kegiatan ini diperoleh gambaran mengenai peta situasi, potongan memanjang dan melintang sepanjang jalur perencanaan pipa gas serta tampak sebaran layanan yang terjangkau. Peta-peta tersebut diharapkan dapat digunakan sebagai dasar perencanaan untuk jaringan pipa gas bagi rumah tangga terutama di lokasi yang dilakukan survey dan pemetaan
