Abstract

The condition of rivers in Indonesia in 2018,  25 rivers were heavily polluted, while in 2019,  38 rivers were  heavily polluted . Efforts are needed to determine the carrying capacity of river pollution loads so that they can be used as guidelines for river management. This study aims to provide an overview of the  conditions of  Indonesia’s rivers through a literature review. This literature review  uses 10 articles from the Google Scholar database for the period 2014-2020. The rivers under study do not have a pollution  load capacity, namely the Code Yogyakarta river, the Bengawan Solo watershed of the Surakarta and Karanganyar sections, the Brantas river in Malang City, the Kupang river, Pekalongan City, the Mahakam river in East Kalimantan, the Winongo river, Sleman Regency, the section of the Brantas river Kekep-Punden Kota Batu, the segment of the Pesanggrahan river of the City; Garang river, Central Java Bedung river, Denpasar City.   Most of the parameters that exceed the loading  capacity of the entire river are BOD, COD, TSS, nitrite, nitrate, phosphate, and ammonia. The source of pollution in most rivers is  unidentified (certain and uncertain sources of pollution). Generally, river management efforts are not carried out in an optimal manner to maintain water quality and condition .

Abstract

Government, through the Head of the Communication Bureau, Public Information Services and Cooperation, Ministry of Energy and Mineral Resources, conveyed a plan to build household gas networks in more than 50 districts and cities that aim to balance the mix of fossil energy use in society. The prepaid system is a payment system that allows users to enjoy services after making a payment. It aims to limit the service as needed, while the postpaid system allows its users to use the service indefinitely during the time span given by the service provider. Currently, the household gas network is equipped with postpaid meters, but it does not rule out the possibility of a prepaid system being applied if it is able to provide better convenience and comfort. Based on the research we conducted to determine public response of Cikarang society against the payment system, as much as 55% of the total sample studied preferred to use the postpaid system rather than the prepaid system on the household gas network. However, it is possible to use prepaid payment system for household gas networks (respondent's result is 35%) if the supporting facilities are continuously improved and developed for better service in the future.

Abstract

Fischer-Tropsch (FT) Synthesis has been widely known for centuries as the process of converting syngas to liquid fuels. Several reactors including Slurry bubble column, fluidized-bed, and fixed bed reactors have been used for FTS on an industrial scale. Although science has seen remarkable development in technology for FT synthesis, the industry still faces challenges in optimizations of process parameters and achieved desired selectivity.  Extensive research has been continuously conducted to seek the best FT reactor offering heat uniformity and efficient heat transfer across the reactor to increase the catalytic activity and its lifetime. Dielectric Barrier Discharge (DBD) plasma has become one of the options to deal with these issues. This reactor work under low temperature delivers a synergistic effect between plasma and catalyst to break H2 and CO bond. DBD plasma is also suitable for feedstock with high H2/CO molar ratios. It is also found that FT catalyst such as cobalt catalyst used in DBD plasma was well dispersed on the support which in turn favour the selectivity toward liquid hydrocarbon.

Abstract

The number of people utilizing the city market facility is likely to increase day by day. It causes  the market conditions to become congested. Therefore, it cannot be denied that  the  existing main roads are definetly affected by this condition. For this reason, the performance of the roads needs to be further reviewed since they are openly accessed by the community also due tothe influence of Teratai Market activities. A descriptive method is used in this studyby surveying the conditions of the Komyos Sudarso road. The calculation  is carried out based on the Indonesian Road Capacity Manual (MKJI) 1997. The results of this study shows that the activities of the Teratai Market greatly affect road capacity resulting in the increased of traffic volume. When the market operates, the trafficbecomes denser as  such a large number of vehicles are commuting on the road. The observation area is included in a commercial area with high roadside activity as evidenced by a side friction survey which shows a high side friction class count with a weighted frequency of 508.3. The results of the road performance show that Jalan Komyos Sudarso is still not saturated, in which the DS value is 0.34 and the average speed of light vehicles is 42 km/hour.

Abstract

The problems that occur in the company is the production system make to order, for example PT. XYZ. Unknown certainty the amount of the order lenses will be produced. So it is not known how labor should be allocated to each shift. Then used the approach of dynamic programming to optimize the number of workers per shift in the PT. XYZ. This study aims to determine the analysis of the dynamic programming optimization to allocate the amount of labor per shift to be effective. The type of research data is primary data obtained through direct observation in PT. XYZ. The results of the research based on the calculation of the forward recursive dynamic programming: shift 1 = 105 people, shift 2 = 104 people and shift 3 = 104 people. While the solution of the optimal allocation of labor for each shift based on the calculation of the backward recursive dynamic programming: shift 1 = 105 people, shift 2 = 104 people and Shift 3 = 104 people. Then the PT. XYZ should allocate 313 workers, so that the allocation of labor to each shift is optimal according to the order received
