Kabupaten Rokan Hulu merupakan sebuah kabupaten hasil pemekaran Kabupaten Kampar yang beribu kota di Pasir Pangaraian, Provinsi Riau. Pembangunan transportasi pada daerah ini harus mampu menunjang upaya pemerataan dan penyebaran pembangunan daerah. Kebutuhan akan pergerakan selalu menimbulkan permasalahan, khususnya pada saat orang ingin bergerak untuk tujuan yang sama di dalam daerah tertentu dan pada saat yang bersamaan pula. Penelitian ini bertujuan untuk mengetahui besarnya estimasi sebaran pergerakan masyarakat di Kabupaten Rokan Hulu dengan memahami pola pergerakan menggunakan metode sintetis (interaksi spasial) yang biasa disebut model gravity (GR) dalam bentuk Matrik Asal Tujuan (MAT) dan garis keinginan (desire line) dengan System Informasi Geografis (SIG). Sebaran pergerakan dilakukan dengan membagi Kabupaten Rokan Hulu menjadi 16 zona. Analisis sebaran pergerakan menggunakan Model Gravity dengan Batasan-Bangkitan-Tarikan (PACGR). Sebaran pergerakan terbesar yang terjadi di Kabupaten Rokan Hulu sebesar 75% berbasis pergerakan internal dan 25 % berbasis pergerakan antar zona. Sebaran pergerakan antar zona terbesar yang terjadi di Kecamatan Pendalian IV Koto yang mempunyai tujuan pergerakan ke kecamatan Rokan IV Koto. Sebaran pergerakan terbesar yang terjadi untuk Kecamatan Rambah Samo, Kunto Darussalam dan Pagaran Tapah mempunyai tujuan pergerakan ke kecamatan Ujung Batu. Hal ini dikarenakan Kecamatan Ujung Batu merupakan pusat industri dan perdagangan di Kabupaten Rokan Hulu

Welfare have a relative explanation, dynamic, and quantitative. Quantitative formulation of welfare is never final because it will continue to evolve along with the development needs of human life. In 2011, the National Team for the Acceleration of Poverty Reduction (NTAPR) made priority sector that can serve as a benchmark the welfare in a region. From the priority sector will be made cluster or group which contains all 33 provinces based on the level of public welfare in the region uses data in 2012 were sourced from the Central Statistics Agency (CSA). The method that can be used to group the 33 provinces is K-Means Cluster method with number cluster as many as two, three, four, and five clusters. K-Means Cluster method is one of cluster analysis method who can partition the data into one or more clusters, so that the data with the same characteristics are grouped into the same cluster and data with different characteristics grouped into other clusters. To know the most optimal of the number of clusters we use Davies-Bouldin Index (DBI). We concluded that the optimal number of cluster is three with details the province in the first clusters have superiority in four sectors like net enrollment rate of primary school, net enrollment rate of junior high school, IMR (Infant Mortality Rate), and access to electricity. The province in the second clusters have superiority in one sector, that is open unemployment rate. The province in the third clusters have superiority in all sectors. Keywords: Welfare, NTAPR Priority Sector, K-Means Cluster Method, Davies-.Bouldin Index (DBI)

Clean water is a need that must be met for everyday, both individual needs and the needs of household groups. The quality of water that is needed everyday is colorless, no smell and dirty, the village of estuary in the middle of the morning is an area close to oil wells and highlands that have very low levels of water cleanliness. Muara Fajar Barat village has high iron content so that it cannot be used for consumption and even for bathing. The West Dawn Estuary community must buy water for daily needs with costs incurred every 3 days reaching 50000 rupiah or an average of 13,000 every day. The economic conditions of the underprivileged people are added to the economic burden with daily expenses by issuing the clean water financing. With this condition there needs to be a solution offered in order to reduce economic burdens and environmental friendliness, for that we need an innovative water purifier tool with a distillation method using natural ingredients and a paralon pipe as a wrapper. The water filter that is made can meet the needs of every daily household by spending only 100,000 euros every 2 months. The decline in the burden of the eastern dawn estuary community could reach 140000 rupiahs every 2 months or 70000 rupiahs
