Authors: Suripin  , Ulfiana D , Budieny H , Parmantoro PN , Prastiwi D 
Published: March 2021

Abstract
Changes in land use can lead to an increased risk of flooding in an area. One example of flood conditions due to land use change is that occurred in the Diponegoro University Campus area in Tembalang. Most parking lots in this area comprises of conventional paving block system. It is basically a permeable pavement types, but in reality, existing conventional paving block systems cannot infiltrate storm water into the soil. There are two possible causes: first, the type of paving block is not a permeable type of concrete paving block and the second is the open graded base (OGB) and subbase do not have a high permeability, or a combination of both. This condition generates stormwater runoff in this area to be high, and causes on site and/or out side inundation. In this study, permeable paving block system (P2BS) was developed to find the parking lots with zero runoff.

Abstract
Reducing CO2 in nature is the reason for the development of alternative technologies such as mortar geopolymers. This will have an impact on reducing the use of Portland cement. Moreover, the potential of local materials is also feasible to be developed especially contains an ingredient that can support environmentally friendly alternative materials. This study aims to determine the mechanical behavior of geopolymer mortars that consist of sand, fly ash type F from Tanjungjati Jepara, white soil from Kupang NTT (as substitution of fly ash), and Potassium Hydroxide (KOH) 8M as an activator. The specimens were cube 5x5x5 cm3 and molds similar to number eight. The mix proportion was 1 binder : 3 sand. Binder is a mixture of fly ash, white soil, and KOH 8M solution with w/b of 0.5. Mortar dried in the oven until 24 hours at 60 °C. Specimens were tested for compressive and tensile strength, density, and porosity within a specified time. The results show that the substitution of white soil in geopolymer mortar can increase of the compressive and tensile strength, increase porosity, and make the weight of volume the mortar become lighter. The substitution of white soil at 10, 20, and 25% shows a trend that has a better result than the others, while the substitution of 5% has not been effected yet.

Abstract
In designing a building, the shape and facade have a very important role. Green building is a high-performance building designed to be responsive to the environment, economically sufficient profit, and as a healthy place to live and work (environmentally responsible, economically profitable, and healthy places to live and work). The concept of ‘green’ is not just a current trend, but must be treated as a basic principle when we start designing buildings. The characteristics that emerge from the design of the shape and facade of a building will form the image of the building itself. To find out the explanation of the concept of the shape and facade of a building, in this research qualitative research with content analysis method is used, through a study of the main building with a case study of the building of LP2M UNNES Sekaran Gunungpati Campus by applying descriptive analysis content. From the analysis study, it will be known that the building has undergone a transformation in the form of addition and subtraction. In designing environmentally friendly buildings is actually a process. The goal is not to make a perfect building, but rather to create a better building. One of the advantages gained in applying the Green Building concept is efficiency. In terms of the facade of the LP2M UNNES building, it appears that in the processing of the embodiment of the shape of the building, of course it is also influenced by material elements, color, proportion, rhythm, and texture. From these studies it is expected that the facade elements of the appearance of a building will show the identity and character of the building.

Authors: Zhang Lei , Han Weixiao 
Published: March 2021

Abstract
Lime stabilization has opposite effects on mechanical and hygric property of earth material. In order to determine the optimal lime content for earth material sourced from Turpan, the effects of lime content on both mechanical and hygrothermal properties of lime stabilized earth bricks (LSEB) are investigated simultaneously. The results indicate that there is an obvious correlation existed between the mechanical performance and lime content, and the max value of compressive strength and the minimum of loss of compressive strength after freezing-thawing cycles appear at lime content of 6 wt%. This phenomenon has been explained by effect of lime stabilization on the compactness inside LSEB matrix. When lime content is 6 wt%, thermal conductivity of LSEB is 0.9169 W/(m K) which is considered to be a tiny increase in comparison with LSEB without lime. In addition, all LSEB specimens are capable for regulating the indoor relative humidity.

Abstract
As an important part of state-owned assets, roads and other transportation infrastructure are an important foundation for the sustained and healthy development of the national economy. It is extremely important to increase the service life of roadways. Aiming at the highly restricted multi-objective optimization problem of roadway maintenance, this paper considers the three dimensions of construction schedule, cost and quality, and proposes an elitist evolutionary multi-objective optimization algorithm based on the concept of ϵ-dominance, called ϵ-multi-objective genetic algorithm variable (εv-MOGA) to solve roadway maintenance problems. Experimental results show that the algorithm can help decision makers choose the most suitable solution among a large number of feasible solutions.

Abstract
Phosphates are important components in the fermentation medium for biosurfactant production. In the present study, Ochrobactrum intermedium strain XY-1 was used as the experimental strain, the effects of various phosphates used in the biosurfactants fermentation media was preliminarily investigated on cell growth, and surface tension, and emulsifying activity of fermentation broth. Under the same total phosphorus concentration of 0.035 mol/L, KH2PO4 + Na2HPO4, KH2PO4, and Na2HPO4 was respectively used as the phosphorus source of biosurfactant fermentation at 30 °C and 160 rpm. The results showed that the bacteria grew slowly and the maximum emulsifying activity of fermentation broth reached 52.95% in the fermentation with KH2PO4 + Na2HPO4 as phosphorus source, and larger bacterial growth and 35.9% maximum emulsifying activity exhibited in the fermentation with KH2PO4, smaller bacterial growth and 24.54% maximum emulsifying activity exhibited in the fermentation with Na2HPO4. The phosphate mixture of KH2PO4 and Na2HPO4 benefits the biosurfactant fermentation by limiting the growth of Ochrobactrum intermedium strain XY-1, which might be the earliest report on the phosphorous source of biosurfactant fermentation by Ochrobactrum intermedium.

Abstract
Freshwater aquaculture is a prominent activity in Rawang sub-basin of the Selangor River. Despite the importance good water quality in daily life, there is limited study on the impact of aquaculture activities on water quality. This paper discusses water quality parameter status (pH, dissolved oxygen (DO), ammoniacal nitrogen, turbidity, total suspended solids (TSS), chemical oxygen demand (COD) and biochemical oxygen demand (BOD)) based on Water Quality Index (WQI) in the aquaculture-impacted Rawang sub-basin of Selangor River and develops the Inverse Distance Weighted (IDW) maps showing water quality status by using GIS (ArcGIS 10.2.1 software) in order to identify the potential aquaculture impacted sites. Seven river sampling sites were selected including Guntong (SR1), Guntong’s tributaries (SR2/control), Kuang (SR3 and SR7), Gong (SR4), Buaya (SR5), and Serendah (SR6) using random sampling techniques based on accessibility and proximity to aquaculture farms. Seven water quality parameters were recorded and analysed on a bi-monthly basis. Results revealed that Guntong, Kuang, Buaya and Serendah rivers had moderate water quality, whereas Gong River was significantly polluted. The control river recorded clean water quality status. One-way analysis of variance (ANOVA) showed that there were significant differences in all measured water quality parameters among sampling sites (P<0.05).

Abstract
Ecologically, mangroves play an important role because they have high primary and secondary productivity so they can support the existence of flora and fauna that live in mangrove ecosystems. Mangrove as a feeding ground is appropriate habitat for macrofauna associated in mangrove such as macrozoobenthos. The objectives of the present study were to assess the community structure included species abundance, biological indices, and the distribution pattern of macrozoobenthos species as a study of secondary productivity in mangrove non-rehabilitation and rehabilitation. The different characteristics of mangrove ecosystems cause the differences not only species richness but also the abundance of macrozoobenthos. The research started from May to September 2018. The determination of research stations was carried out by a purposive sampling method and there were 6 observation stations with 3 replications. Sampling was conducted in 1 x 1 m2 of square transects. The results of the study found 15 species of macrozoobenthos and the commonly number of species and species abundance found was higher in diurnal than nocturnal time. The highest abundance was Faunus ater (64.7 individuals/m2), and they were found mostly at station 4 (mangrove rehabilitation) which was 32.7 individuals/m2 (nocturnal) and 18.7 individuals/m2 (diurnal). On average, the diversity index (H’) was moderate both in diurnal and nocturnal time. The evenness index value implied that the total number of individuals in the species was almost the same and there was probably no domination of certain species at field study. The species distribution pattern was random. In conclusion, the community structure of macrozoobenthos in the present study was in moderate condition.

Abstract
Quality inspections in agricultural product industries is a critical step to ensure high standard of the products. The main purpose of this present study is to apply the near infrared spectroscopy as a rapid and simultaneous method in determining inner quality parameters of intact mango fruits as vitamin C and total acidity. Absorbance spectra data of mango samples were acquired using a portable sensing device NIRS in wavelength region of 1000-2500 nm and resolution windows 0.02 nm. On the other hand, actual vitamin C and total acidity contents of mango fruit were measured by means of standard laboratory procedures. Prediction model were built using raw and enhanced spectra data with partial least square regression approach. The results showed that both quality parameters can be determined simultaneously with maximum correlation of 0.92 for vitamin C and 0.94 for total acidity. It may conclude that near infrared spectroscopy can be employed for a rapid and environmental friendly approach in mango quality inspections.

Abstract
A low emission development strategy (LEDS) is designed to develop action programs and policies to place a country on a development pathway that is resilient to climate change while working towards measurable long-term reduction of greenhouse gas emissions. Aceh’s efforts to protect forests have shown a steady rate of reduction in deforestation from 2013-2017. However, the threat still exists, so that an integrated strategy with other sectors is needed to ensure that the goals of tackling climate change and reducing deforestation can be achieved. The data sources for this study are primary and secondary in nature and were carried out by following the basic structure of the ‘SWOT’ analysis (Strengths, Weaknesses, Opportunities and Threats). Some of the strategies produced in this study to involve stakeholders and government are: 1) District, Provincial and National level governments implement policies and regulations that are synergistic between institutions; 2) Traders, Exporters / Cooperatives and Collectors monitor the performance of certified coffee and overcome market failures; 3) The Gayo Coffee Protection Society (MPKG), Universities and Research Institutions apply Geographical Indications in every export product and support research funds; and 4) Coffee farmers / planters undertake technological interventions, develop market-based strategies, and develop risk management schemes.
