    Shoreline change is a natural process caused by the transported sediment generated by nearshore current to preserve the mass rates. Shoreline change can be a shoreline loss called abrasion as well as shoreline expansion due to sedimentation called accretion. Abrasion and accretion phenomenon can be regarded as a threat if they cause damage or potentially disrupts human activity. Identification of land use as well as geographical and physical condition of a region can be approached by satellite image analysis. This research uses Landsat Satellite imagery to observe shoreline changes based on the position of shoreline recorded through satellite images of 2004, 2010, and 2016. The image of one period overlapped with other period images is used to calculate the increment or decrease of shoreline occurring at a particular location. The results of this study will show the trend of increasing or decreasing the shoreline based on certain time and positio

    Distribution transformer has an important role in the distribution of electric power in a distribution system. So that the transformer can operate with both the condition of the transformer must be in a stable condition. One of the things that can damage the transformer is non-linear load, such as computers, printers, air conditioning (AC) equipment lab in every department and equipment other electronics that may cause harmonic on the network power systems, content of harmonic high can cause a condition of distribution transformer overheats and if not treated immediately will cause transformer life time becomes shorter. This study aimsto determine the harmonic correlation to the increase of temperature on the distribution transformer in the Faculty of engineering University of Riau

    Efek Kombinasi Jenis Pupuk Organik Dengan Bionutrisi Terhadap Pertumbuhan Dan Hasil Tanaman Jahe (Zingiber Officinale Rosc.) Pada Inceptisols Di Garut

    Percobaan untuk mengetahui pertumbuhan dan hasil tanaman jahe padakombinasi jenis pupuk organik (pupuk kandang domba, bokashi pupuk kandangdomba, dan Bios) dengan Bionutrisi, dilakukan dari bulan Desember 2000 sampaiApril 2001 di Desa Haruman, Kecamatan Leies, Kabupaten Garut. Percobaanmenggunakan Rancangan Acak Kelompok (RAK) yang terdiri dari enam perlakuandan diulang sebanyak empat kali. Adapun perlakuan tersebut adalah P1 = 30 tonpupuk kandang domba/ha, P2 = 30 ton pupuk kandang domba/ha + Bionutrisi 3cc/L, P3 =10 ton bokashi pupuk kandang domba/ha , P4 = 10 ton bokashi pupukkandang domba/ha + Bionutrisi 3 cc/L, Ps = 6 ton Bios/ha, dan P6 = 6 tonBios/ha + Bionutrisi 3 cc/L. Hasil percobaan menunjukkan bahwa tanaman yangdiberi 30 ton pupuk kandang domba atau 10 ton bokashi domba atau 6 tonBios/ha mengahasilkan bobot jahe segar/rumpun yang tidak berbeda. Aplikasi 3cc Bionutrisi/L tidak memberikan kenaikan hasil yang signifikan, tetapi kombinasi6 ton Bios/ha dengan 3 cc Bionutrisi/L cenderung memberikan hasil yang relatiflebih tinggi (yakni 206,0 g rimpang jahe segar/rumpun atau sekitar 12 ton jahesegar/ha). Pupuk Bios 6 ton/ha (20 % dad dosis pupuk kandang domba) dapatdijadikan altematif untuk mengganti pupuk kandang pada pertanaman jahe

    Information and communication technologies, the growing human needs will push the information quickly and accurately. As in the field of tourism, fast and accurate information is needed in order to facilitate the tourists to reach tourist destinations that will be targeted. Promotion and marketing of tourist attraction which was conducted by the Department of culture and tourism of the city of Palembang was a print media such as mass media, booklets with tour maps are dynamic but not this method is still not enough to convey the information accurately to tour domestic and foreign tourists. Therefore, through the design and development of information system of tourism based android mobile is able to facilitate tourists in finding existing tourist information in the city of Palembang. This system utilizes the internet and technology Location Based Service (LBS) using the GPS (Global Positioning System) which was built on the Android platform. As for the system development methods used is RUP (Rational Unified Proces) using the concept of the Unified Modelling Language (UML), while the diagram is the Use Case diagrams, Activity diagrams, Sequence Diagrams, and Class diagrams. Information in the form of tourist maps are displayed in the Library of Google Maps Apis. The result of the final project of tourism information system Architecture-based Android Mobile with the approach of Beriorentasi objects on the Department of culture and tourism of the city of Palembang is capable of displaying travel information, tourism as well as the supporting means of tourist sites in the form of a dynamic tourism maps

    Tajwid Lake is an oxbow lakes that located in the Langgam District, Pelalawan Regency,Riau Province. The potency of the Tajwid Lake is currently under reviewed by the governmentof Pelalawan as it will be developed into a tourist destination. Water quality in the lake Tajwidmight be changed as a result of human activities conducted around the lake. A study aims toprovide basic information on water quality and determine the trophic status of the lake wasconducted in February 2016. There are three stations (Station 1, Station 2 and Station 3) and thewater was sampled from three depths, surface, middle and the bottom of the lake. The samplingswere conducted 3 times, once / week. The water quality parameters measured were depth,transparency, temperature, pH, free CO2-, DO, Nitrate and Phosphate concentration. Resultsshown that the depth of the lake was ranged from 6.3 to 12.3 m, transparency 51.3- 69 cm,temperature 27.7-30.3 °C, pH 5, dissolved oxygen 2.3-8.3 mg / L. Free carbon dioxide ranged4.9-13.9 mg / L, nitrate 0.02- 0.11 mg / L, phosphate from 0.02 to 0.1 mg /L. The Nitrate andphosphate concentrations indicate that the condition of the Tajwid Lake is between oligotrophicto mesotrophic
