Published: February 2020

Abstract
Population growth in Indonesia which is increasing causes the need for land to be used as a residential space or housing space to increse. One of the regions in Indonesia that experienced a land cover change of paddy fields into settlements is Somba Opu Sub-District, Gowa Regency. Somba Opu Sub-District is directly adjacent to Makassar City in the North. An effort to overcome changes in agricultural land to non-agriculture land is by making policy regarding the Sustainable Food Agriculture Land. The definition of the Land of Sustainable Food Agriculture is a field of agricultural land that is determined to be protected and developed consistently in order to produce staple food for independence, resilience, and national food sovereignty. The methods used in this study are observation, interviews using questionnaires, and studying the documentations. The criteria of the respondents in this study were paddy field farmers. In determining the number of respondents, this study uses the Slovin formula. The criteria for Sustainable Food Farming are based on Regulation of Ministery of Agriculture No. 7 of 2012. The result shows that Somba Opu Sub-District has an area of potential for Sustainable Food Agricultural Land covering an area of 214 ha and Sustainable Food Agricultural Reserves Land covering an area of 854 ha.

Authors: Ardhiansyah Nicolaus Nino , Mahendarto Trias 
Published: February 2020

Abstract
Indonesia traditional market was one of the main economic centres in the past, where farmers, fishermen, gardener, and those whose products were connected to the natural resources could sell their products and consumers could buy them with much cheaper prices. Now, with the rise of small scale supermarkets, online shopping, door-to-door sellers, and more modern marketplace, the traditional markets are threatened to lose their customers. There are also the degrading images of traditional market in the society that further discourage consumers to visit the marketplace. Salaman traditional market is one of the traditional markets that is being affected by these changes, and has begun to lose its customers. With the size of the marketplace’s site, the location, and the economic importance it holds for its suppliers, Salaman District will face a major economic and urban problem if Salaman Traditional Marketplace is to be closed. The government has begun to take notice of the problem by trying to modernize the marketplace, but without careful analysis and full consideration of the main problems, Indonesia might lose one of its unique historic building typologies. This research wishes to evaluate the main reasons on why Salaman market is in the downwind, and using empirical study and primary data collection backed by literature and historic study, this research will try to pinpoint the problems in order to have the best approach to revitalize the marketplace. The steps that is being suggested in the Salaman traditional marketplace can become a precedent for other traditional marketplaces in Indonesia that are facing similar problems, and how the marketplace can still become a cultural and economic centre for the people that surround it.

Published: February 2020

Abstract
Historical records of disasters in the world find in scriptures, history books, geography, and folklore. This study aims to analyse the mitigation of Mount Kelud eruption with ancient manuscripts. The research method is by examining the ancient script “Goenoeng Keloet,” which is in Javanese with an old spelling. The results showed the difference in height and changes in water sources, and increased temperatures around the mountain, and many indicators of small fish that died mention in ancient manuscripts as a sign of mountain eruption. Ancient manuscripts also say about mitigating volcanic eruptions by planting tamarind trees, no land clearing in the land path, and no houses building.

Published: February 2020

Abstract
This paper studies the effect of compaction temperatures on Marshall properties on a Hot Rolled Sheet-Base (HRS-Base) mixture with the addition of plastic waste. Polyethylene terephthalate (PET) type plastic waste from plastic bottle waste is used in this study as an additional material of HRS-Base mixture. The ‘wet method’ is used to mix the PET into HRS-Base mixture, in which the PET is pre-mixed with asphalt material at the temperatures between 160 °C to 170 °C to create modified asphalt before it is mixed with HRS-Base aggregates. The materials used in this study consist of PET from plastic bottle waste, 60/70 penetration asphalt, Portland cement, and aggregates. The aggregate composition used must meet HRS-Base specifications based on the Indonesian National Standard (SNI). The results showed that increasing the compaction temperature of the HRS-Base mixture had an impact on increasing density, Voids Filled with Asphalt (VFA), Marshall stability, and Marshall Quotient (MQ), while the values of Voids in Mix (VIM), Voids in Mineral Aggregates (VMA), and Flow decreased. In addition, HRS-Base without the addition of PET plastic (conventional HRS-Base) and HRS-Base with the addition of PET plastic (modified HRS-Base) were compared. Conventional HRS-Base has a density value, Voids Filled with Asphalt (VFA), and Flow higher than those of modified HRS-Base. While, the value of Voids in Mix (VIM), Voids in Mineral Aggregates (VMA), and Marshall stability of conventional HRS-Base are lower than those of modified HRS-Base.
Strengthening the Role of Sharia Public Banking in the Indonesian Construction Industry: Towards an Atmosphere of Sustainable Urban Development
Authors: Fatwa Nur 
Published: February 2020

Abstract
The sharia public banking is one of the major finacing methods in Indonesian contraction industry. The big sharia banks such as BTPN Syariah, Bank Syariah Mandiri, BNI Syariah, and BRI Syariah (named CR4) play a major role in financing construction industry in Indonesia. The CR4 monopolize the construction industry that causes an unfair competition, while the Financial Control Authority (called Otoritas Jasa Keuangan, OJK) has yet issued regulations that favor small- scale banks. As a result, this competition causes the impact on inequality in financing construction service projects. This paper analyzes the competition within the banking industry, especially sharia public banks, the factors that affect the level of competition, and the improved regulation by the OJK in order to mitigate the competitive fringe competition in the construction financing. This study emphasise that the capital has a significant positive effect in the form of minimum capital limitation regulation. With this regulation, the small scale sharia public bankings would be merged and financially stronger to support the construction projects. This revised regulation aims to achieve the distribution of sustainable urban development implementation in Indonesia.

Published: February 2020

Abstract
Temef Watershed is located in the Benanain River Basin with a catchment area of 551.50 km2. River characteristics in the Temef Watershed are influenced by three main river streams from upstream to downstream. Conventional collection of data on watershed characteristics requires a relatively long process and time. However, when based on Geographic Information Systems (GIS), the cost and time will be more efficient. The floodwater level is affected by the amount of rainwater runoff that occurs in the Temef Watershed. The amount of runoff depends on the level of soil permeability and land cover. To determine the level of soil permeability, hydrogeological maps are used. Based on this, a study of the characteristics of flood waters from GIS-based hydrogeology is needed. The analysis method used ArcGIS overlay on hydrogeological maps, while data on watershed characteristics used the Archydro and HEC-GeoHMS features. The results of the analysis showed a level 3 permeability type with limestone lithology, solid volcanic breccia, sandy marlene, conglomerate, and alluvium consisting of sand and gravel having moderate to high permeability. The metamorphic and basalt rocks have low to moderate permeability and the scaly clay has low to very low permeability. This condition causes runoff that turn into flood streams.

Published: February 2020

Abstract
A spillway is one of the most important features of a dam. It should be able to allow flood discharge to flow and keep its structure stable. The force impacting a spillway is great; hence, it needs a proper design. The design philosophy of a spillway is to maximize its discharge while keeping the water level in the dam low. The discharge capacity of a spillway is mostly predicted based on empirical data derived from idealized conditions with laboratory experiment. To determine actual capacity, a physical test model is usually utilized. However, a physical model needs large amounts of space and time to prepare. Computational Fluid Dynamics (CFD) offers an interesting method to predict spillway capacity with less time and resources. In this paper, a simulation of flow over an Ogee spillway was performed using the open-source CFD platform called OpenFOAM. The flow is simulated based on the Volume of Fluid (VoF) method to resolve the dynamics of free surface. The simulation results show a good agreement with experimental measurements and the USBR method of calculation.
Study on flow regime change due to weir construction plan in Batang Asai River, Sarolangun, Province of Jambi
Authors: Rizaldi Akbar , Farid Mohammad , Riyando Moe Idham , Kendra Herryan 
Published: February 2020

Abstract
The weir design process not only considers the location, dimensions, strength, and durability of the weir structure, but must also be consider the effect on the flow characteristics in the river after the weir, especially related to the flow velocity characteristic around the weir. The water level will rise and affect the flow velocity downstream of the weir. Because of the fall of water, the velocity will greatly increase and the river can erode. The weir construction on the Batang Asai River, specifically located in Sarolangun, Province of Jambi, has unique conditions that cause the velocity of water after the weir to increase. Several alternatives will be analysed as solutions to deal with changes in flow velocity. The alternatives are groundsill, riverbed normalization, and river crossing widening. It was found that the alternative of river widening showed a significant reduction in flow velocity.

Published: February 2020

Abstract
Declining potential of water resources and the highly increased exploration of water resources along with highly increased needs in society demand the analysis of water balance of the Gandong Watershed in Magetan Regency. Analysis results showed that surface water availability that comes from discharges, springs, and drilled wells is 35.144 m3/s in the dry season, 48.050 m3/s in the low season, 59.833 m3/s in the normal season, and 78.163 m3/s in the peak season. The availability of subsurface water is 163.650 m3/s. The surface water requirement of Gandong Watershed is 183.580 m3/s with 55 irrigation areas, and the subsurface water requirement is 118.990 m3/s. The highest surface water deficit is in the Jejeruk Irrigation Area, with 13.680 m3/s or only 1.23% of the needs met in December (dry season), and the highest surplus is in the Gemblung Irrigation Area, with 10.430 m3/s or 100% of the needs fulfilled in February (peak season). Water balance evaluated by the Water Evaluation and Planning (WEAP) Software showed only 10 irrigation areas met 100% of the demand. Subsurface water balance is at a surplus condition from January to December. Land water balance is at a deficit condition from May to December.

Published: February 2020

Abstract
An accurate determination of water availability of Amprong River has an important role in the planting system to support the agricultural production process in the Kedungkandang Irrigation Area, because if the availability of water is not precisely determined, there will be an error in regulating irrigation water. To overcome these problems, a good analysis system is needed. One of the time-series models is the ARIMA (Autoregressive Integrated Moving Average) model. The model was built by discharge data from 9 periods from 2008/2009 to 2016/2017, and its purpose was to predict the discharge of the 2017/2018 period. There were only five models feasible for use. The best model is the ARIMA model (2, 0, 1) (1, 2, 1)36 with values of MSE = 22.90; KR = 6.00; MSD = 8.05; MAD = 2.04; MAPE = 18.53; and MPE = -8.98.

Published: February 2020

Abstract
The purpose of this study is to determine the condition of water quality, trophic status, abundance and type of phytoplankton, and pollution load, as well as to formulate a conservative effort for reservoir management based on Lahor Reservoir conditions in 2017. The data needed for water quality analysis are total P, NO3-N, NO2-N, NH3-N, BOD, DO, TSS, and pH; hydrological and reservoir data such as rainfall data, the volume of the reservoir, reservoir catchment area, and Lahor reservoir outflow; as well as data on abundance and types of phytoplankton. The results of the water quality analysis of the Lahor Reservoir showed that it did not meet Class II water quality standards and trophic status, being eutrophic to hypereutrophic, which means the Lahor Reservoir has become polluted. The abundance of phytoplankton that occurs in the Lahor Reservoir exceeds the limit of the phytoplankton abundance that has been determined and is dominated by Microcystis blue-green algae. Therefore, the recommended efforts are bioremediation techniques, regulation of reservoir operation patterns, application of the Trophic Level-Based Aquaculture (TLBA) system, and introduction of rotifer zooplankton.

Authors: Widyaningsih Ida , Abu Bakar Bakhtiar , Kusdian Didin 
Published: February 2020

Abstract
Pangandaran Regency is located in the Province of West Java and consists of the subdistricts of Parigi, Cijulang, Cimerak, Cigugur, Langkaplancar, Mangunjaya, Padaherang, Kalipucang, Pangandaran, and Sidamulih. The capital of Pangandaran Regency is located in Parigi Sub-District. The rapid growth in the area has resulted in increased water demands, which in turn has resulted in an imbalance between water availability and water needs. To restore the function of recharge areas, Pangandaran Reservoir was built in order to conserve water. In addition to its function to recharge, the reservoir can be used as a source of raw water supply for Pangandaran Regency. In its operation, the water collected in the reservoir must be used optimally to meet the needs of various sectors. To achieve this goal, a study of reservoir operations is needed. This study of reservoir operations includes analysis of rainfall, analysis of water availability using the F.J. Mock method and NRECA, analysis of reliable discharge, and analysis of needs for various needs such as irrigation and drinking water for the people. By using water equilibrium as well as minimum and maximum storage limits (effective storage), the fulfilment of water needs for domestic, municipal, and irrigation or industrial use can be known.

Published: February 2020

Abstract
Floods that occur in the Upper Citarum River Basin are generally caused by flood discharge that exceeds the capacity of the Citarum River. Dayeuhkolot is one of the areas that is often flooded in the Upper Citarum River Basin. The Citarum River Authority has made efforts to handle floods in Upper Citarum by constructing the Nanjung Tunnel. When floods occur, Nanjung Tunnel will function to divide the water partially into the tunnel and through the Curug Jompong. SOBEK Model was utilized to find out the effect of the Nanjung Tunnel against flood inundation in Dayeuhkolot. This flood modelling also accommodates other efforts that have been made by BBWS Citarum such as the Cieunteung Pond and Cisangkuy Floodway. A 20-year return period was used for modelling. From the results of the modelling, it was found that difference in flood inundation area with and without the Nanjung Tunnel was 12.5 Ha or 3.5 %, with the duration of the overall inundation being reduced by 4.9 hours. Nanjung Tunnel does not have a great influence on the area of inundation, but it has an effect on reducing the duration of floods that occur in Dayeuhkolot.
Potential use of crushed pyroclastic rocks from mount Kelud as alternative backfill materials
Authors: Primantyo Hendrawan Andre , Suprijanto Heri , Yuliani Emma 
Published: February 2020

Abstract
Pumice and scoria are pyroclastic rocks that can be found where volcanic mountains appear. In Indonesia, pumice and scoria are found in large deposits in the area of Mount Kelud at Kali Putih River in Blitar Regency, Province of East Java. Thus, it is important to evaluate their potential uses as alternative backfill materials. Standard Proctor compaction tests were conducted to determine the maximum dry density (MDD) and optimum moisture content (OMC) to evaluate their compaction properties. Constant head permeability tests were also conducted to determine the coefficients of permeability. Direct shear tests were also applied to investigate the shear strength characteristics of these materials. The results showed that the MDD values of scoria are slightly higher than pumice. The OMC values of pumice and scoria are 23% and 15.5%, respectively. The internal friction angle of pumice and scoria are higher than natural sand, which are approximately 55-64º and 46-59º respectively. Pumice and scoria with different relative densities had coefficients of permeability that ranged from 0.0003 to 0.002 cm/s and 0.001 to 0.002 cm/s respectively. Due to their mechanical properties, it can be concluded that these materials have potential as alternative backfill materials.
Acute Stress-Induced Coagulation Activation in Patients With Remitted Major Depression Versus Healthy Controls and the Role of Stress-Specific Coping
Authors: von Känel Roland , Merz Franziska , Pfister Hildegard , Brückl Tanja , Zimmermann Petra , Uhr Manfred , Holsboer Florian , Höhne Nina , Ising Marcus 
Published: February 2020

Abstract

Background
Depressed patients have an increased risk of myocardial infarction, for which acute stress is a frequent trigger. Prothrombotic changes could be one involved mechanism that can be modulated by psychological coping.

Purpose
We examined the effects of remitted major depression and situation-specific coping strategies on stress-induced coagulation activation.

Methods
Forty patients with remitted depression and 23 healthy controls underwent the Trier Social Stress Test, rating applied coping strategies thereafter. Blood was sampled at baseline and 15 and 45 min poststress to measure fibrinogen, von Willebrand factor (VWF) and D-dimer. Coagulation activation over time was quantified as area under the curve (AUC) with respect to baseline activity. Standardized z-scores of individual coagulation AUC measures were added up to a prothrombotic index.

Results
Stress provoked significant VWF (p = .024) and D-dimer (p = .002) responses. Remitted depressed patients used positive distraction coping more frequently than controls did (p = .030). Coagulation AUC measures were similar in both groups. In all participants, higher positive coping total (p = 0.009), driven by devaluation/defense (p = .022) and distraction (p = .004) coping, was associated with a lower prothrombotic index. In controls, but not in remitted depressed patients, higher positive coping total (p = .008), driven by higher devaluation/defense (p = .010) and distraction (p = .023) coping, was associated with lower VWF AUC.

Conclusions
Despite the use of favorable coping strategies in a specific stress situation, remitted depressed patients may benefit less from a positive effect of positive situational coping on coagulation activation than controls. Such a mechanism could partially explain the increased risk of myocardial infarction in depressed individuals.
