The main equipment used is nine pieces of SSF Pipe, each has 4 inches in diameter and 50 cm in length with Pantai Panjang Bengkulu’ssand as the filter medium. The inlet positions tested were 90°, 45° and 0°; repeated three times and arranged in a completely randomized design (CRD). The observed variable is the weight of the captured pollutant in the SSF at the distance of 10cm, 20cm, 30cm, and 40cm from the inlet. Results of the research showed that the number of pollutant particles caught along the flow path in the SSF decreased following a linear model as the distance from the inlet was increased. The number of pollutant particles caught also decreased with the decrease of inlet position slope. The inlet position significantly affected the number of pollutant particles caught along the flow path; the position of 90° causes the highest amount of pollutants to be caught and significantly differs from that of the position of 45° and 0°. The position of 0° causes the least amount of pollutants to be captured that considered to be the best inlet position so far. It is important; however, to research whether inlet position of more than 180° could result in a much smaller amount of pollutant caught along the flow in the  SSF Pipe.Keywords: SSFPipe, inlet position, particle caught in SSF, peat water filtration","PeriodicalId":397828,"journal":{"name":"AGRITROPICA : Journal of Agricultural Sciences","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133924022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The poverty level was quantified method by comparing household income with the World Bank poverty line, i.e. US $ 2/capita/day. Households were categorized into poor if their income is less than US $ 2/capita/day or Rp 26,908.00/capita/day (with an exchange rate of Rp 13,454.00 per US $), vice versa.  To determine factors affecting the probability of poverty occurrence, the binary logistic model was applied.  The results showed that the average non-plasma farmer household income was Rp 39,484.00/capita/day. With the level of exchange rate applied in this research, it was found that forty percent households were below the poverty line.

Initially, the contents of soil Cmic, Nmic, Pmic, DHA, and APA increased gradually during 2-14th days of incubation (DAI), again increased significantly at 28th DAI and then decreased slowly at 60th DAI in all treatments under both series.
