The aim of this research was to examine the effect balance of bokashi and inorganic fertilizer on growth, simplicia yields and secondary metabolites of sinensetin kumis kucing varieties. The design of research was a split-plot field experiment, with the main plot were varieties (Orsina 1 and Orsina 2) and subplots in bokashi fertilization of goat manure (control, bokashi 15 tons ha-1, bokashi 15 tons ha-1 + 100% inorganic fertilizer dose recommendation, bokashi 15 tons ha-1 + 50% recommended dosage of inorganic fertilizer and 100% recommended inorganic fertilizer). Inorganic fertilizer recommendations consist of Urea 100 kg ha-1, SP36 200 kg ha-1, and KCl 100 kg ha-1. The results showed that the use of bokashi 15 tons ha-1 + 50% inorganic fertilizer increased growth. Besides it also produced the highest simplicia of 48.57 g plant-1 and the highest secondary metabolite of 0.045% plant-1 in Orsina 1. Both kumis kucing varieties did not show growth differences and yields. Bokashi fertilizer can reduce the use of inorganic fertilizers in the growth and simplicia yields and potentially increase sinensetin of kumis kucing.","PeriodicalId":36463,"journal":{"name":"Sains Tanah","volume":"336 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77389248","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}

Land conversion and improper land-use have been widely recognized as the main cause of environmental damage since the demands for agricultural lands become greater than land resource available. The objective of this study was to determine the concept of appropriate land-use planning through environmentally sound spatial management in order to prevent land and environmental degradation. The sub-district of Antang Kalang was chosen as study area representing sloping lands in humid tropic that have a susceptibility to erosion. Conservation approach by the use of USLE erosion risk prediction model and land evaluation through land suitability classification was used in this study. The geographic information system (GIS) and remote sensing (RS) technology were applied to generate spatial basic information and to assist in spatial analysis. Two crops, upland rice, and rubber, representing food crop and estate p have been selected based on the local resource that has been existed since a long time ago. The result of spatial analysis shown that the arable land for agricultural practices covers 9,039 hectares (23.19%) while for non-arable land, it is allocated for forest preservation with total areas 29,934 hectares (76.81%). Land-use planning and land resources management involving conservation aspect and land suitability evaluation should be taken into account for farming practice at sloping lands areas since the value of soil loss potential appears as an indicator of erosion risk. Permanent cultivation system and the intercropping farming system is the option of recommended agricultural practice at sloping lands in the humid tropic that have a susceptibility to erosion.","PeriodicalId":36463,"journal":{"name":"Sains Tanah","volume":"65 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90831457","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}

Nowadays the use of biodegradable coating materials for slow-release fertilizer (SRF) is preferable because of environmental issues. This research was aimed to make SRF using starches and cellulose as the coating materials and to test the release rate of the nutrients. Five kinds of starches (cassava, corn, sago, wheat, and glutinous rice) and carboxymethyl cellulose (CMC) were used as coating material for granulated NPK fertilizer. The coated fertilizers (NPK SRF) were tested for their leaching rate in the soil by percolation experiment. The results showed that the kind of starch used influenced the release rate of the NPK SRFs. The NPK SRF coated with sago starch exhibited slow release rate and low leached nutrients which also resulted in slow growth of corn plant, as expected of SRF. The use of starch and CMC as biodegradable coating materials in this research has a possibility to affect the microbial activity in the soil so that the nutrient release became faster than the uncoated NPK fertilizer.","PeriodicalId":36463,"journal":{"name":"Sains Tanah","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75791287","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}

Thus, this research aims at investigating the dynamics of groundwater and its nutrient status condition for the purpose of supporting plant cultivation in the second crop after rice planting. The study was conducted in Banyu Urip Village, Tanjung Lago Telang II, Banyuasin. The plant used in this activity was paddy, with the treatment of a ratoon cultivation system. The ratoon system is paddy cultivation by using the first paddy planting season shoots. A urea treatment was given with a dose of 0 kg/ha (control) and a dose of 150 kg/ha. The results of soil analysis showed that, although not significant, there was an increase in the nutrient status of the soil condition. Therefore, it can be concluded that fertilizing was considered ineffective for the system of ratoon cultivation. The study of groundwater dynamics showed that at the early phase, a groundwater table was dropped above 30 cm (critical) but it could increase by the rain and water retention in the canal. The average of the groundwater table during the ratoon period was at the depth of 5-30 cm below the soil surface, allowing it to be suitable for plant growth. The plant growth at B treatment was better and its production was 2.8 ton/ha. This 2.8 ton/ha plant production was classified as a high category for paddy with the ratoon cultivation system. There is no effect of the fertilizer treatment on the nutrient status in the soil. Moreover, the application of fertilizer did not give a significant result on the production of rice.","PeriodicalId":36463,"journal":{"name":"Sains Tanah","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80936788","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}
