Pekalongan Residence has a relatively many sand and gravel deposits particularly in river area. Nowadays,many locations have been exploited by local residences or investors from other regions. Sand and gravel miningis being done since 1980s, thatâ€™s why it can created devastated land in that surrounding area of mining. As theresult of that condition, it is called for the research to determine how devastated land condition during or aftermining. Factors used in this research to determine devastating land are mining technique, rate of mining, depthof slope mining, width of mining hole, relief of digging base, characteristics of material slope, tilt of diggingslope, reserving of top soil and overburden, erosion stage, vegetation cover, reclamation. Devastated landbased on mining has vary in low and high scale. In the gullies river,most of them in low devastated landcondition. Meanwhile, devastated land in border of river vary in low up to high. Several places which are havehigh devastated land are Sastrodirjan (Wonopringgo District), Dororejo(Doro District) and Krompeng (TalunDistrict). In deposit bar, has low up to high devastated land. High devastated land are Pododadi (Karanganyardistrict), Sastrodirjan (Wonopringgo district) and Kaligawe (Karangdadap district).

Kiln is an equipment which has vital existence in the manufacture of cement. Kiln firing requires a hightemperature to produce a clinker. Higher combustion temperature allows heat transfer occurs on the surfacecoating on the walls of the kiln that is not evenly distributed, so most of the heat is absorbed. As a consequence,it requires large amounts of fuel. Heat efficiency in the kiln is important to know. Production of clinker in thekiln which occurs at high temperatures, will also release a variety of gases, such as CO2. Carbon dioxide isincluded as one of the greenhouse gas, this gas will negatively impact the earth's ozone. Therefore, need to knowthe range of greenhouse gas that is formed, in order to determine the appropriate mitigation and prevention.Evaluation result of heat efficiency in the kiln is 43,17% by generating greenhouse gas emissions amounted to6,173 tonnes CO2 equivalent / tonne of coal.

We observe the surface deformation of the Mt. Bromo which located at eastern Java Indonesia area that includes neighborhood volcanic system on TNBTS (Taman Nasional Bukit Tengger Semeru). Recently, remote sensing has played as an important role to observe volcano behaviour. We apply the SAR Interferometry (InSAR) algorithm referred to as Small Baseline Subset (SBAS) approach that allows us to generate mean deformation velocity maps and displacement time series for the studied area. The common SBAS technique, the set of interferometric phase observations writes as a linear combination of individual SAR scene phase values for each pixel independently. Particularly, the proposed analysis is based on 22 SAR data acquired by the ALOS/PALSAR sensors during the 2007â€“2011 time interval. A fewer studies have been able to show capability of InSAR analysis for investigating cycle of volcano especially of Mt. Bromo which characterized eruption stratovolcano in ranging one to five years. The results expected in this work represent an advancement of previous InSAR studies of the area that are mostly focused on the deformation affecting the caldera. According to the result, we expected this study could implement on risk management or infrastructure management.

[Title: A Change of The Facade of a House in Recidential Woningpark Gergadji Semarang] Indis architecture is an assimilation or a mixture of elements of Western culture especially the Dutch with Indonesian culture, especially from Java. Woningpark Gergadji (Park Housing Gergadji or NIS - Park) is a residential complex that is occupied by employees and their families who work in the NIS / Nederlands Indische Spoorweg Maatschapij (now PT . KAI DAOP IV) since the Dutch colonial era. The houses in the housing preserved and maintained . But now every home no longer has the same view of the facade as the first appearance of the facade of the colonial period look even additional buildings that resemble a home between homes - the original home. This thesis discusses a changes the facade of the main house at Recidential Woningpark Gergadji performed by residents since occupied. If there is a change of the facade that does not follow the rules that match the architecture of the building, it will make the facades of the building will lose its identity. A growing phenomenon in that houses, there is a change in the facade of the main building and the new building increased in the land. Therefore, the PT. KAI DAOP IV and residents today must work well together so that the houses retaining the architectural identity. Â
