In this research was analyzed the effect of flow rate of wastewater treatment to remove turbidity, zinc, and iron. The applied flow rate of membrane separation was of 7 L/min and 14 L/min and the operation time was of 90 min respectively. The rejection concentration of turbidity, zinc, and iron decreased with increasing the flow rate at adsorbent fly-ash. Whereas at the hybrid membrane UF-RO, the rejection concentration of turbidity, zinc, and iron increased with increasing the flow rate. The maximum rejection of turbidity was 24.26%, 95%, and 67.89% for adsorbent fly-ash, UF membrane, and RO membrane respectively. The maximum rejection of zinc was 91.67%, 59.70%, and 14.81% for adsorbent fly-ash, UF membrane, and RO membrane respectively. The maximum rejection of iron was 62.24% and 21.62% for adsorbent fly-ash, UF membrane respectively. The pollutants concentration in the permeate was met the quality standards of the Indonesian health department through the decision of the Minister of Health number 907 of 2002 concerning supervision of the quality of drinking water.","PeriodicalId":31278,"journal":{"name":"Sriwijaya Journal of Environment","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87381570","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}

Planting these crops must be carried out on a land that is suitable based on the results of a land suitability evaluation. A framework to evaluate the land suitability for many land uses is initiated by Food and Agricultural Organization (FAO) in the late 1970’s. As the advent of smart phone nowadays becoming ubiquitous technology to solve problems in most settings, such as education, agriculture, medicine, psychology, and many others. This paper is to capitalize such advantage by converting the framework into a mobile app. This solution is hoped to help land users or planners to be more effective and efficient in evaluating their land. An algorithm is employed in the form the Rule Based System (RBS) in a way to construct the framework into bunch of rules that connect each other, resulting the conclusion of suitability. The rules itself are working on some variables, namely annual rainfall, altitude, drainage, soils’ type, pH, flood risk, fertility of the soils, soil solumn depth, etc. This study focuses on three medicinal crops only, which are candlenut, cardamom and onion to be evaluated. Data of agro climatic that were determining the suitability of the crops were developed into general and specific criteria for the plants. A usability model was studied from 40 respondents using the app. It is found that the usability of the app was in “very good” classification, with dimension scores, ranging from 3.79 and 4.22.","PeriodicalId":31278,"journal":{"name":"Sriwijaya Journal of Environment","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76807174","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 Riding Village occupied around 10,000 hectares land because they felt that the company and the government had never asked their permission to make the land an industrial planted forest. The community has evidences that the land belongs to their ancestors, namely “sonor” (planting rice by burning land first) and trenches for timber by their ancestors in the region. In July 2013, the people of Riding Village and Bumi Mekar Hijau LLC agreed to resolve land conflicts through an open, concrete and successful dialogue process. Both parties appointed Wahana Bumi Hijau (WBH) and Imparsial Mediator Networking (IMN) as mediators who assisted the negotiation process.

This is done so that the capture CO2 from air can be used as a feedstock or raw material for producing carbon free renewable fuels by applying direct air capture (DAC) process. This way of capturing is gone to be possible with using some solid & aqueous sorbents in pilot plant. The success of this capturing process is depended on the appropriate configurations of both major & minor plant operations. Heat & mass balance are required necessarily to contribute on the finding of each pilot plants data. The design of this process is modeled like this so that the captured CO2 can be delivered at 15MPa into the pilot plant & for this, the requirements of energy inputs are about 8.81GJ or 5.25GJ of natural gas & 0 KWHr or 336KWHr of electricity respectively. Then all the results finding from the pilot contactor, reactor, calciner are optimized to reduce the processing cost of the capturing process. It is observed after the ending of the process that the amount of operating cost is ranged between 50$ to 100$ to capture per ton of CO2 from surrounding air where the total levelized cost of the whole process ranges between 94$ to 232$/t-CO2. If it considers the other specific choices such as financial safety, environ mental & ecological arrangements etc. then this DAC process would be the best reliable solution to capture the CO2 from air in upcoming decades.","PeriodicalId":31278,"journal":{"name":"Sriwijaya Journal of Environment","volume":"116 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89419685","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 research resulted that socio-economic determinant factors causing peatlands degradation are complex and integrated each other. Based on clustering the main sequence of causing peatlands degradation was performed by increasing population; increasing poverty; win-win approach; security of land ownership; and agricultural infrastructure and expansion respectively. Understanding this cluster with a comprehensive approach is needed to decide what factors play in the degradation of peatland, so that the policies made are precise and targeted.

This study is aimed to analyzing strategies used to cope with disguised unemployment in the tidal agricultural sector through a combination of technological innovation and income diversification. The study was carried out in the tidal lands in Province of South Sumatra, Indonesia in 2017. This study employed a quantitative method with a survey technique. Simple random sampling was conducted to determine each subject population.The analysis was carried out using tabulative, mathematical, and simulation method. Technological innovation in agriculture gave to the rising number of disguised unemployment in tidal agriculture sector. But, with technological innovation and income diversification, disguised unemployment will be decreased and farmers' income will be increased, yet, the productivity will be low. In other words, to cope with the issues of disguised unemployment, technological innovation in the agricultural sector should be accompanied with the income diversification. However, we should be noted that the combination of agricultural technology innovation policy and income diversification affects to decreasing on household productivity The results are, by and large, useful for policy makers in designing in arranging disguised unemployment policies.","PeriodicalId":31278,"journal":{"name":"Sriwijaya Journal of Environment","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81017704","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}
