Item Penerapan Ahp Dalam Menentukan Prioritas Utama Srategi Pemenuhan Kebutuhan Air Bersih Di Pulau Merbau(wahyu sari yeni, 2019-01-09) Joleha, Joleha; Mulyadi, Aras; Wawan, Wawan; Suprayogi, ImamThis paper discusses the problem of how to determine the main priority of the strategy to meet clean water needs that can be applied to small islands, especially on Merbau Island using the Analytic Hierarchy Process (AHP) method. This study began with a survey of 100 family heads by distributing questionnaires. The questionnaire contains questions relating to personal data, and data about the components of rainwater harvesting. The opinions of experts were asked in this matter to determine the values considered by experts in determining strategies for meeting clean water needs on Merbau Island. Then an analysis is carried out using the AHP program. The results showed that the fulfillment of recommended water requirements on Merbau Island was to maximize household scale rainwater harvesting (RWH). Maximizing rainwater harvests on a household scale is a top priority with the support of the availability of adequate clean water facilities and infrastructure. In relation to clean water facilities and infrastructure, it is expected to use a rainwater harvesting technology system, therefore the criteria of technology have the highest value, but in the field it is difficult to implement by the community so government support is needed in realizing it. Government support is highly expected because 44% of the island's population Merbau is a poor person who naturally prioritizes basic needs rather than providing good and right rainwater harvesting facilities and infrastructure.Item Penilaian Kesesuaian Lahan Dan Degradasi Tanah Gambut Yang Digunakan Untuk Perkebunan Kelapa Sawit Di Area Hgu PT. Subur Mandiri Lestari(wahyu sari yeni, 2019-01-03) Wawan, WawanIn recent years it has been claimed that the use of peat land for oil palm production was declared to be damaged. To clarify these claims, the research has been done with the purpose of evaluating the suitability and degradation of the peat soil which is used for oil palm plantation in area of PT. Subur Mandiri Lestari (PT.SML). This research has been done with survey method. The research location was determined with purposive sampling methods. While the sampling is done with transect method and the sampling point on every transects was determined with free grid method. On this research there is two transect, each transect had set for 5 and 4 sampling point. The determination of land suitability class is done with limiting factor method with matching technique, while the determination of peat land degradation was done with comparative method. The result of analysis shows that the peat land which is used for oil palm plantation in the area of PT. SML have an actual land suitability class of S3-f (marginally suitable with pH and low base saturation as limiting factor) and the potential land suitability of S2 (suitable). The results of the analysis of peat degradation indicate that peat land are used for oil palm plantations in the area of PT. SML if referring to PP No. 71/2014, PP No. 57/2016 and PP no. 150/2000 all damaged (degraded). However, if the degradation analysis refers to BBSDLP (2018), then the peat land is not degradedItem Respon Padi Gogo (Oryza Sativa L.) Terhadap Pemberian Silikat Dan Pupuk Fosfat Pada Tanah Ultisol(2018-02-06) Zulputra, Zulputra; Wawan, Wawan; Nelvia, NelviaThe research aims to study the response of upland rice on the application of silicates and phosphate fertilizer on Ultisol. The study was conducted in land Ultisol in Pematang Berangan Village, Rokan Hulu Regency, Riau Province. Research in the form of experimental factorial completely randomized design consisting of two factors. The first factor is silicate consists of four levels (0, 50, 75, and 100 kg SiO2/ha), while the second factor that phosphate fertilizer consists of four levels (0, 36, 54, and 72 kg P2O5/ha), each combination was repeated three times. The results showed that application of silicates and phosphates increase the growth and yield of upland rice. The application of 100 kg SiO2 and 36 kg P2O5 per hectare increasing of the percentage of grain pithy and weight of dry grain per square meter, about 21% and 117% respectively compared to without silicates and phosphates
