Abstract

The application of sewage treatment in New Delhi should implement the treatment processes, which are easy to be operated and is not costly operational and avoid the complexity of the operating system of STP. The renewed interest in alternative onsite treatment technology by using a constructed wetland (CW). Canna lily, an ornamental plant that has an aesthetic value, is very suitable for an alternative plant for a constructed wetland. This study aims to observe the ability of canna lily for phytotechnology implementation in a constructed wetland. This study is known as a range-finding test (RFT), which served as a preliminary test. Observation is conducted by preparing variation concentration of wastewater; 25%; 50%; 75%; 100% and 0% as control, which was injected into the wetland. CW (60 cm long, 60 cm wide and 60 cm deep) contained gravel medium height 25 cm with a wastewater volume 3 L. Observation measured the height of the plant, the color of the leaf, and DO, and BOD concentration. The observation was conducted for about 25 days, in term of 15 days for range finding test and 10 days for acclimation. The results show that Canna lily could grow well, though it has some part of the withered leaf, reach height significantly, and indicated decreasing concentration of organic parameters. It is conjectured that Canna lily is very possible for a constructed wetland application.

Abstract

Many advantages are obtained in treatment using microalgae. Microalgae treatment using an oxidation ditch can remove organic matter in wastewater. On the other side, the wastewater treatment using microalgae with oxidation ditch algae reactor (ODAR) to reduce organic matter also produces by-products that are harmful if dissolved in water. Processing in ODAR has Effluent Organic Matter (EfOM) and Algae Organic Matter (AOM) which are by-products of the microalgae process. The content of these compounds can lead to the formation of DBPs in water. This research was conducted on control variation (without microalgae) and variation of the volume of waste and microalgae 1:3, with oxic and oxic-anoxic conditions. Spectroscopy FTIR test is used to determine the organic matter contained through its functional groups. In the oxic-anoxic control variation, the FTIR percentage increased to 46.63% on the fifth day. In control oxic variation, it decreased to 46.12%. Meanwhile, in the oxic-anoxic 1:3 variation, the percentage decreased on the fifth day to 46.39%, and in oxic conditions, the rate was 46.8%. From the results obtained, the addition of microalgae can increase the content of organic matter in processing due to the by-products produced by microalgae and bacteria in processing.

Abstract

Infrastructure development in an area, including the construction of toll roads, is aimed at developing a region and increasing the economy of the region. The construction of the toll road which is connected from Krian-Manyar-Gresik is carried out to facilitate traffic connecting the two cities. Traffic jams often occur at the link between the two cities. Congestion that occurs is usually caused by an increase in the volume of vehicles. Therefore, the construction of a toll road connecting the two cities is the best alternative. This research aimed to know government policies effectiveness in the construction of this toll road. The method used in this research is to use a dynamic system approach. From the results of the traffic simulation model design, it is found that the construction of toll roads is considered very influential and can be a way out of congestion problems. This is due to a decrease in the degree of saturation of congestion and although there is an increase from year to year, it is only slightly and not too significant. So the researchers suggest to continue the planned toll road construction project.

Abstract

Small and medium Enterprises (SMEs) are a group of one of the largest economic actors in the Indonesian economy and have proven to be a safeguard for the national economy in times of crisis and also create sizable job opportunities for domestic workers, thus greatly assisting efforts to reduce unemployment caused by difficulties looking for jobs. This research is classified into qualitative research. Respondents were taken using purposive sampling technique. The method used is analysis using SWOT (Strengths, Weaknesses, Opportunities, and Threats). The results of research with SWOT analysis show that in managing finances, they still use traditional records, in products they still use recipes for the taste and quality of food and beverages, in promotions they are passive in waiting for consumers, strategic locations and neatly arranged.
