Authors: Kurniawan Dody 
Published: February 2020

Abstract
This study is motivated by the issue of conflicts of interest between pedestrian users and Trans Jakarta transportation service users. Current pedestrian functions aside from being a means of transferring human movements developed into a means of transit (Pedestrian Transit) of human movement. Sidewalks in the station area become a new transit point for human movement and need to be managed wisely. The existence of the Trans Jakarta shelter on Jalan Manggarai Utara 1, Manggarai Station greatly facilitates the transit of Jakarta residents who want to move to use the train facilities. On the other hand, the existence of the Trans Jakarta shelter on Jalan Manggarai Utara 1, raises problems with pedestrians. The condition of the Trans Jakarta shelter is currently taking up part of the sidewalk space, so pedestrians must go out of the sidewalk to continue their journey. This study was conducted to find out the existence of sidewalks as transit pedestrians.
From the formulation of the problem, a descriptive method will be carried out. a descriptive method is carried out to make a description, description systematically factually and accurately regarding the facts, characteristics and relationships between the phenomena investigated.

Abstract
This study discusses the support of water related to the relationship between the region and availability, and its effects in the future, including the direction of spatial planning, and air requirements based on population development in the Cibinong catchment. In general, there are two main stages consist of several supporting aspects, carrying capacity of water-based on water availability and water needs. In the first stage consisting of: prediction analysis of land cover change; hydrological analysis to determine the planned rainfall for calculating the discharge of the plan; calculation of potential discharge seen from the ability of the land to collect water; and calculation of the ideal area and volume of reservoirs of water bodies. For the water needs stage are based on the calculation of demand discharge based on population projections, and land use; in accordance by applicable standards. The results show that Cibinong Urban area infiltration water experiences a downward trend from an increase in value of 0.16 m3/s/day to only 0.01 m3/s/day. As for the availability of surface water based on runoff water tends to rise statically. But the potential that can be used today as an urban water source is only 1.26 m3/s/day.
Do the state and market affect the farmer’s sovereignty? Study of organic agriculture in indonesia
Authors: Ningrum V , Subroto A 
Published: February 2020

Abstract
Many studies reveal organic farming as an environmentally friendly way compared to conventional agriculture. However, there is a lack of social issues discussed, such as farmer sovereignty, which has a significant impact on farmers’ sustainability in running their organic business and their social welfare in the long term. This paper aims to analyze whether government policies and market interventions affect the farmers’ sovereignty as defined in the Nyéléni declaration. We use organic farmer surveys in 4 provinces in Indonesia, which represent coconut, nutmeg, sorghum, and rice farming. By using the Partial Least Square (PLS), we concluded that government intervention has significantly influenced the condition of farmers’ sovereignty but not for market intervention. This result indicates that organic agriculture grows naturally based on nature and community. The implication is the government needs to provide capacity building for organic communities rather than by subsidizing organic fertilizers, organic seeds, and machinery as in conventional agriculture and needs to legitimate organic label guarantees from the farmer’s community.

Published: February 2020

Abstract
The growth of the creative economy and advances in information and communication technologies have led to a significant change in how space is both produced and consumed. Nowadays, people can work in a variety of locations, regardless of the space or time. This change has brought with it the need for new and flexible workspaces that allows people to collaborate, thus increasing the phenomenon of co-working space in urban areas. The purpose of this study is to identify the distribution of co-working space locations and determine the factors that influence user preferences in choosing such locations in DKI Jakarta. This study employed the nearest neighbour method and principal component analysis. The research concludes that the distribution patterns of co-working space in DKI Jakarta are clustered. The densest locations of co-working space are distributed in the central area of offices, trades, and services. Meanwhile, the factors influencing consumer preferences in choosing co-working space are location and fare factors. There is a strong relationship between the co-working space locations frequently visited and the choice of transportation types. Thus, co-working spaces that do not provide large parking areas tend to set lower rates, while their users tend to use public transportation. This implies that the government can facilitate collaboration and thus, has a strategic role to play in the development of the creative economy in the city while building strong networks with other development stakeholders in the Penta-helix.
Spatial Distance And Mode Of Transportation Choices In Jabodetabek Metropolitan Area: A Sakernas 2017 Micro-Data Analysis On Commuting Pattern Of Workers
Authors: Chotib  
Published: February 2020

Abstract
The growth of Jabodetabek (Jakarta-Bogor-Depok-Tangerang-Bekasi) Metropolitan Areas raises several problems including the occurrence of traffic congestion in various parts of the metropolitan area. This congestion occurs partly because of the increasing number and use of private vehicles, especially by workers who commute mobility within the Jabodetabek metropolitan areas. The pattern of movement from the place of residence to the place of work in the metropolitan area is also a factor causing congestion. The purpose of this study is to find out the extent to which the distance factor measured by geographical distance and the proximity of the area between the place of residence and place of work has an impact on the preference for the use of transportation modes by workers who are commuting. In accordance with the availability of data in the Sakernas 2017 (National Labor Force Survey 2017) Micro Data, the transportation mode preference consists of two choices: public transportation mode or private transportation mode. The Sakernas 2017 micro data analysis was conducted with descriptive analysis (cross tabulation) and inferential analysis (Binary Logit Regression). The analysis shows that the probability of using public transportation tends to be used by workers whose travel distance is longer (above 10 km), in areas that do not directly border between residence and workplace, female workers, young workers, workers with education Junior high school and below,and workers who work in the agricultural sector. Urban managers covering the Greater Jakarta Metropolitan Area should continue to disseminate and promote the importance of using public transportation in travel from place of residence to place of work to reduce traffic congestion and urban air pollution.

The behaviour of fluid flow in a 90-degree (sliced) nonlinear bend
Authors: Abduh Moh , Suhardjono  , Sumiadi  , Dermawan Very 
Published: February 2020

Abstract
The behaviour of flow due to nonlinear bends in piping networks involves the occurrence of contractions and turbulence that begin when approaching the upstream part down to the downstream part; these conditions are caused by collisions between fluid particles flowing with pipe walls in sudden direction changes. Though contractions and turbulence occur in all directions along the bends, the normal flow downstream of the bends occurs quite far after the bends. The elements that influence contraction and turbulence are velocities (U), number of slices (n), length of nonlinear walls (Li), sudden angle changes (α), coefficient of friction (f), acceleration of gravity (g), and the slope of the pipe base (I). A higher flow velocity in a pipe leads to farther laminar flow returns downstream of the bends, and a smaller flow velocity leads to the flow returning to normal downstream shortly after the bends. The simulations of this research involved a 10 m/s initial velocity with a 25.4 mm pipe diameter and the number of slices (n) = 2; normal flow was achieved at 22D after the nonlinear bend. With similar velocity and different diameters of pipes, the length of contraction, turbulence, and laminar flow were equal. This analysis is expected to provide optimal benefits for performance in the usage of nonlinear bends in activities related to piping networks, especially the primary network, which uses large-diameter pipes.

Published: February 2020

Abstract
Riverbeds in the Mt. Merapi area are dominated by gravel originating from Mt. Merapi. The 2010 Mt. Merapi eruption has formed a riverbed consisting of sediments of various size. Since then, the morphology of the rivers has changed dynamically, depending upon the natural and the anthropogenic factors. Most of the rivers drain into the Progo River, whereas the main river system of Progo River drains into the Indian Ocean. The dynamics of the tributaries of volcanic rivers along the Progo River are the major concern to identify the capacity of the tributaries against potential lahar flow disasters that may occur. This paper presents the results of a series of observations of several tributaries of the volcanic rivers, taking into account the natural flow phenomena as well as the sediment mining activity along the river under investigation. The investigation included the hydraulic simulation, which employed a numerical model. The results of the simulation showed that the downstream part of the Progo River is influenced by sediment from Mt. Merapi through its tributaries. These also suggest cost-effective river tributary maintenance to mitigate the risks of lahar flow disasters.

Published: February 2020

Abstract
This paper presents the hydraulic flow system in a fishway to simulate the flow of a pool-type fishway. A fishway is a waterway to allow some fish species to pass by a human-made obstruction in a river or stream. The construction on the river, which has no fishway, will impact the river ecosystem balance. The purpose of this research is to give an alternative to reduce negative effect on the river ecosystem because of the obstruction. The velocimeter and the flow type in fishway must be able to be passed by the fish. In a kind of the pool-type fishway, there is an orifice in the bottom that has a potential supercritical flow before it becomes subcritical flow. The purpose of this experiment is to identify the surge in the pools of the fishway. The physical model of the pool-type fishway in Sembayat Barrage, Gresik was created to analyse the hydraulic condition of the flow in the fishway structure. The velocity has a greater value than the permissible velocity of the fish, and thus several fishways are not able to function optimally because the fish refuse to swim through the fishway. From the results of the study, it can be concluded that the velocity can be reduced by adding baffles at the downstream part of the orifice.

Published: February 2020

Abstract
This paper presents a study carried out to assess the accuracy of several sediment transport functions commonly applied in HEC-RAS 4.0 against data from the sediment flushing of Wlingi reservoir in 2016. Another aim of this assessment is to evaluate the viability of selected transport equations to simulate riverbed changes during the sediment-flushing event. Thus, the best scenario of sediment flushing could be determined according to their efficiencies. The overall accuracy of the transport function indicated by RMSE values in descending order were those of Laursen-Copeland, Ackers and White, Meyer-Peter and Müller, and Wilcock formulas, when applied to the observed data. The study also indicated that Laursen-Copeland formula had parameters that were commonly well-characterized by the riverbed of Wlingi reservoir. Further, it was suitable to be utilised to assess the achievement of sediment flushing in Wlingi reservoir, while others seem less satisfactory.
Utilization of a pond in East Jakarta for a sustainable urban drainage system model
Authors: Chalid Abdul , Prasetya Bagus 
Published: February 2020

Abstract
High population growth in the area of East Jakarta has led to more construction of settlements, including in several areas of East Jakarta, which includes Jalan Pengantin Ali in Ciracas Sub-District. When very heavy rains fall in the rainy season, this place is often flooded, while in the dry season there is a scarcity of raw water or clean water. This study examines the application of sustainable drainage systems with the technique of making a retention pond as a flood control alternative. The purpose is to hold water runoff during the rainy season so that it does not enter the river directly, and so that some of the collected water could be used to meet the clean water supply needs of the people. The calculation of rainwater potential used the height of the monthly average rainfall. The retention pond capacity was determined by the pool simulation method during the rainy season. The planned flood discharge was calculated using the Nakayasu HSS method. The obtained results indicated a peak discharge value with a return period of 2 years that amounted to 8.84 m3/sec. The planned retention pond area is 6380.94 m2, with a retention pond height of 4 m, a dike slope of 1:1, and the elevation of the overflow base being at an altitude of 38.5 meters above sea level (masl). From the results of the HEC-RAS 5.0.6 software, an optimal overflow width of 2 m was obtained, with an outflow discharge of 4.55 m3/sec and a pond volume of 19530 m3. With the retention pond, flood peak discharge could be reduced by 4.29 m3/sec. This will allow the flood discharge in the rainy season to be reduced and increased clean water needs in the dry season to be met.

Abstract
The quantity of rain that falls on the earth cannot be known with certainty. Floods and droughts due to a small quantity of rainfall are frequent events in some areas of Indonesia. The depth of rainfall at a certain time can be anticipated with accurate information. Along with rapid advances in technology, the forecasting of patterns of rainfall can be performed by artificial intelligence models, using historical data for the climatological parameters. The aim of this study is to predict rainfall depth based on climatology data. There are three categories of data that were obtained using NeuroSolutions for Excel: monthly, daily and hourly data. The input data are temperature, pressure, duration of sunshine, and humidity. The output data is rainfall depth. Based on the results of running calculations on monthly, daily, and hourly data, it was indicated that monthly, daily, and hourly data have relative errors of 11.49%, 8.49%, and 19.32% respectively.

Published: February 2020

Abstract
Reservoir operation is strongly influenced by water balance conditions in the catchment area. The amount of inflow, reservoir capacity, and water requirements are major factors in creating reservoir operation rules. The purpose of this research is to obtain the extent of the reliability of parallel reservoir operation with simultaneous execution by utilizing water transfer from wet to dry watersheds. Reservoir operation rules were derived by utilizing the storage capacity of the two reservoirs with two spillways and two separate water demands in the downstream parts. The various parameters applied for the operation rules are expected to optimize the operation of the reservoirs.
