Judul: Rencana Revitalisasi Lanskap Kota Tuo Sawahlunto, Provinsi Sumatera Barat.
Abstrak: Indonesia has many old colonial cities, one of which is part of Sawahlunto city. The town has a strong dutch colonial history and culture but due to the rapid development of the city, some of the relics have been experiencing changes and damage so needed landscape revitalization effort. Revitalization landscape aims to improve the landscape of the old town towards the modern standards but still respecting and maintaining those old colonial of history and culture character. This research based on landscape historical approach with descriptive research methods (quantitative) either by conducting interviews to obtain data, perform direct observation in the area as well as conduct studies of the literature. From the results of the analysis that has been done, the old town of Sawahlunto experienced extensive change, shape and city planning, population, and economic, social and cultural. However, this town has a value of uniqueness and originality but has undergone little change. For it needs to be done to revitalize the old city's efforts to boost values of authenticity and uniqueness. The value of the originality of the “Kota Tuo Sawahlunto” can be improved by maintaining and revitalizing land use pattern, the pattern of settlements, buildings, and patterns of circulation. While the value of the uniqueness of the “Kota Tuo Sawahlunto” can be increased by keeping the historical relations and revitalize the owned elements/cityscape, keeping the integrity of the historical landscape elements that form a unity of the historical landscape with a strong character, keeping the historic landscape elements of the diversity of societies, as well as maintaining the quality of aesthetics. Revitalization Program that can help improve and maintain the city's characteristics: (1) improve the physical beauty of the area by restoring the cityscape on colonial forms; (2) implement new activities in the area that is closely related to community involvement; and (3) provide input on policy orders to local governments to support the planning and supervise the activities of its implementation.

Judul: Revitalisasi Perkampungan Budaya Betawi di Setu Babakan, Srengseng Sawah, Jakarta Selatan
Abstrak: Perkampungan Budaya Betawi is located in Setu Babakan an engineered village, Srengseng Sawah Village, South Jakarta established by the government as the site of preservation and Betawi cultural development. The purpose of this research is to evaluate the existence of physical component, non-physical and value as well as proposing a revitalization efforts based on potential and assessment landscape. The result of this research are expected to be input for the government as well as provide recommendations on model (template) of Jakarta’s revitalization. This research is done in three community (RW) (7th, 8th,9th) at Srengseng Sawah village, South Jakarta. The method that is used in the inventory/survey, Kappa statistic and assessment of historical and cultural landscape. The research show that kappa coefficients value of region shows the potential areas of conservation (0.819). Based on historical and cultural landscape assessment, the 8th community as a village embryo have the highest value in iii originality and uniqueness of the highest compared with 7th and 9th. Therefore it is recommended that develoved based on balance between phsyical character and socio-cultural value of Perkampungan Budaya Betawi instead of potensial economic activity. Revitalizing it is also recomended that development community participation, so that the efforts taken not only survived in a short time period, but can be sustainable and meet the community needs.

Judul: Kajian Mekanisme Transport Ion pada Membran Telur Ayam Ras melalui Pengukuran Listrik
Abstrak: Telah dilakukan penelitian untuk mengetahui mekanisme transport ion yang melewati membran telur ayam berdasarkan pengukuran sifat kelistrikan membran dengan meninjau pengaruh dari konsentrasi, valensi ion, suhu dan frekuensi. Sifat kelistrikan dapat dilihat dengan melakukan pengukuran tegangan, konduktansi, dan karakteristik 1-V. Pengukuran dilakukan dengan menggunakan dua metode yaitu tanpa pemberian sumber arus eksternal dan dengan pemberian sumber arus eksternal. Pengukuran tanpa pemberian sumber arus eksternal digunakan untuk menentukan nilai tegangan membran pasif. Sedangkan, pengukuran dengan pemberian sumber arus eksternal digunakan untuk menentukan nilai konduktansi listrik dan karakteristik I-V membran. Penentuan tegangan, konduktansi dan karakteristik I-V membran dilakukan dengan cara meletakkan membran di dalam chamber yang diisi larutan elektrolit NaCl, MgCl2 dan AlCl3. Variasi konsentrasi, valensi ion, suhu dan frekuensi mempengaruhi nilai tegangan, konduktansi dan karakteristik I-V membran. Semakin besar konsentrasi dan suhu larutan eksternal maka tegangan, konduktansi dan kemiringan I-V membran meningkat. Ditinjau dari valensi ionnya maka tegangan dan konduktansi listrik membran terbesar ditunjukkan oleh larutan AlCl3. Konduktansi listrik membran akan meningkat dengan meningkatnya frekuensi larutan eksternal. Karakteristik I-V membran telur mendekati sifat ohmik. Pengaruh variasi suhu pada larutan NaCl konsentrasi 0,1 mM dan 10 mM serta larutan MgCl2 dan AlCl3 konsentrasi 0,1 mM tidak memberikan kontribusi yang signifikan terhadap aliran arus. Pengaruh variasi suhu terhadap kemiringan kurva I-V terlihat pada konsentrasi NaCl 100 mM, sedangkan MgCl2 dan AlCl3 pada konsentrasi 10 mM dan 100 mM.
