The dynamics of urban development, followed by various opportunities and challenges for different social groups, indicate a growing sense of complexity, unpredictability, and insecurity about cities and emphasis a need to identify new sustainability strategies. This paper aims at predicting the land-use change of urban coastal areas in Banda Aceh and its impact on urban sustainability. It used an urban simulation model using Cellular Automata (CA), integrated into a LanduseSIM platform. There were three main steps as part of the research methodology: (1) preparation of current data on land uses (2015), (2) simulation of data using CA in LanduseSIM software, and (3) visualization of data and result. Accordingly, the final simulation of the year 2030 was completed, in two scenarios, as the basis to evaluate the impact of land-use change on urban sustainability in Banda Aceh. The study has revealed that the current development trend in the coastal area of Banda Aceh is consuming natural resources such as wetlands and vegetation, driven particularly by the planning of urban coastal region as a center of tourism and fishery, complemented by the upcoming Banda Aceh Outer-Ring Road project. The study recommends a reconsideration of the city strategies by decision-makers to achieve sustainability and ensure ecological balance.

Voltammetry is an electroanalytical method measure current as a function of applied potential. The working electrode in the voltammetry method dramatically affects the result of the electrochemical analysis. Modification of the working electrode can improve measurement performance. In this research, the carbon paste electrode (CPE) was modified with Bentonite (CPEB) to determine copper's level using differential pulse voltammetry technique. CPE and CPEB were used as working electrodes, handmade Ag/AgCl as a reference electrode, and Pt wire as the counter electrode. The measurement parameters were optimized, including the composition of bentonite in carbon paste and scan rates. Furthermore, the measurement conditions were validated, involved linear concentration range, detection limit (LoD), the limit of quantization (LoQ), repeatability, and recovery. The results showed that bentonite's optimum composition was 40% of the total weight of graphite and activated bentonite. The scan rate optimum for Cu2+ measurement was obtained at 20 mV/s with CPE and became faster to be 25 mV/s with CPEB. The linearity of the standard solution measurement of Cu2+ using CPE was in the range of 5 to 100 μg/L and changed to 5 to 500 μg/L using CPEB. LoD and LoQ values of standard solution Cu2+ measurement with CPEB were slower than CPE. The Horwitz ratio calculation was smaller than two for both CPE and CPEB. The recovery of Cu2+ standard measure in sample solution as the matrix was obtained 93,49 ± 6,39%. According to the Decree of the Ministry of Health Number, the level of Cu2+ in the tomato sample was found 6.019 ± 0.69 mg/kg, which is over than threshold value of Cu2+ (5 mg/kg) 03725/B/SK/VII/89.

The existence of traditional houses in Banda Aceh has been extinguished in modern times. With globalization's impact, the traditional house connotates as ‘old house style,’ and thus, the house style is not up to date. A large number of house owners demolish them and reconstruct them with new modern houses. Despite that, it is approved that the traditional houses of Aceh were survived the earthquake that frequently hit the region. As Banda Aceh is one of the regions resided on Sumatran's segment, the region has a large number of earthquakes. This paper, which is part of the previous study on the thermal comfort of traditional and modern houses in Aceh, explores a historical architectural example that reveals local experiences that involve local wisdom and expertise. This paper focuses on a traditional house located in a modern housing neighborhood in Banda Aceh city. In doing this, the paper identifies how Acehnese ancestors, through their local knowledge, have constructed a traditional Acehnese house. The article also shows how its architectural form's construction techniques respond to the region's geographical condition. In constructing this study, interview and observation toward the building as primary data collections are conducted. Also, several written sources, as secondary data, related to an Acehnese traditional house, are reviewed. This paper shows that constructing a conventional house is a responsive architecture toward hot climate and earthquake. Therefore, this architectural building type with the local wisdom value's involvement is worthy of being applied and adapted in modern life.

This research is aimed to examine the catalytic activity of Sawahlunto clay, which is enriched with Ca2+ and Cu2+ transesterification of Crude Palm Oil (CPO) to produce biodiesel. Based on the results of the analysis with X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD), Sawahlunto clay consists of about 61% Si and 24% Al with a Si/Al mole ratio of 2.7 and typical clay mineral consisting of kaolinite and illite, another mineral fund was quartz and goethite. The mineral composition changes after calcination, where kaolinite and illite disappeared. Fourier Transform Infrared (FTIR) analysis shows that calcination can remove the organic compounds Sawahlunto clay; thus, the clay was used without calcination for the next step. Clay samples can be enriched with Ca2+ ions and Cu2+ ions without damaging their mineral composition, where more Cu2+ ions are loaded than Ca2+ ions. The Sawahlunto clay enriched with Ca2+ ions showed a slightly better catalytic activity in the transesterification of crude palm oil (CPO) than its parent clay; when enriched with Cu2+ ions, the catalytic activity did not appear at all. However, the homogeneous counterpart of such catalyst, calcium nitrate, was still the most active and selective compared to all others

Pandrah Weir, built-in 1987, serves the Pandrah Technical Irrigation Area in Bireuen District, Aceh Province, with an area of 1.203 Ha. Its old infrastructure has experienced various damage that can decrease the irrigation system performance. The Pandrah irrigation system's previous performance assessment by both the MASSCOTE approach and Rapid Appraisal Procedure (RAP) evaluation suggested a service level of 3.05 (useful classification). This study assessed the effect of the variables on the Pandrah irrigation system's performance with Structural Equation Modeling (SEM) operated by the AMOS program. The four leading indicators were irrigation service, Water User Farmers Association (P3A), operator Human Resources (H.R.), and irrigation operation modernization. The refinement of irrigation system performance analysis using SEM showed that results of the four irrigation system performance indicators, namely: 0.082 (p=0.768), 0.090 (p=0.273), 0.419 (p=0.287), and 0.606 (p=0.039) for irrigation service, P3A indicator, irrigation operation modernization, and H.R. respectively. Based on the evaluation of the four indicators of irrigation system performance, it is concluded that the Pandrah irrigation system's performance is good. This performance assessment provides a clear picture of irrigation water services, H.R., P3A being an initial assessment for priorities, planning, and scheduling to start modernization programs for irrigation system operations. Irrigation modernization aims to facilitate the operation and maintenance by improving the irrigation system. This modernization means that irrigation planning, irrigation operation, maintenance, and monitoring systems have been carefully calculated before proposing a new irrigation network. The success of monitoring activities requires the use of information technology.

The water settlement has unique and distinctive characteristics, but it can become an environmental problem if the sanitary conditions are poor. The poor sanitary occurred in the water settlement, namely in Makassar Timur and Mangga Dua Utara, which were initially iconic settlements, but now, both of these settlements have environmental degradation. In line with the Sustainable Development Goals, strengthening community participation was carried out to realize clean water and proper sanitation. The research aimed to map the environmental sanitary conditions by involving community participation. This mapping describes sanitary water settlement characteristics to become a planning database to handle both areas' sustainable hygienic. The results showed that the sanitary achievement index in the two regions, above 50% of the conditions were carried or sufficient. The findings showed the mapping of settlement on the water in the two areas, revealed environment condition with the same characteristics in which the environmental conditions had experienced environmental degradation due to contamination of water bodies because of solid and liquid waste originating from residential houses deliverables from upland settlements. In the future, the settlement environment in Makassar Timur District will be planned to be completely stockpiled. As a result, this environmental area will lose its identity as a settlement on the water. Meanwhile, land conflicts occurred in Mangga Dua Utara District's settlement, resulting in the lack of government programs in this environment to structure slum environmental conditions

The use of a low-cost biosorbent prepared from Ipomoea pes-caprae stem for the adsorption of Cd(II) ions from aqueous solution at different contact times, biosorbent sizes, pH values, and initial Cd(II) ions concentration solution was investigated. The biosorbent was analyzed using Fourier-transform infrared spectroscopy (FT-IR) to find important IR-active functional groups. A scanning electron microscope (SEM) was used to examine the biosorbent morphology. The experimental results showed the highest Cd(II) ions adsorption was 29.513 mg/g under an optimal condition as initial Cd(II) ions concentration of 662.77 mg/L, 1 g dose, 80-min contact time, pH 5, 75 rpm of stirring speed, 1 atm, and 30 oC. Cd(II) ions' adsorption kinetics obeys the linearized pseudo-second-order kinetics (R2 = 0.996), and the adsorption capacity is based on the optimal condition, and the rate attained was 44.444 mg/g and 0.097 g/mg. Min, respectively. Besides, the adsorption isotherms were very well fitted by the linearized Langmuir isotherm model, and the monolayer adsorption capacity and pore volume determined was 30.121 mg/g and 0.129 L/mg, respectively. These results indicated the chemisorption nature

Publisher : Graduate Program of Syiah Kuala University

The compressive strength of concrete depends on the physical characteristics of the concrete forming materials. Oyster shells originating from Krueng Neng, Aceh Besar are very abundant, left unattended by fishermen, causing pollution of the surrounding environment. Oyster shell dust contains CaO, which can be used as a partial substitution of cement. Therefore, it is necessary to study oyster shell ash as cement replacement and fine aggregate in concrete production. This research aims to determine the compressive strength of concrete using shell ash as cement replacement and fine aggregate. The oyster shells were obtained from Krueng Neng, Lamjamee Village, Jaya Baru, Aceh Besar District. The oyster shells were crushed with a Los Angeles Test machine and sieved with sieve size 2.36 mm for fine aggregate and sieve #200 for cement replacement. The water-cement ratios (w/c) were 0.4, 0.5 and 0.6. The results showed that concrete's compressive strength with 5% cement replacement level was higher than the concrete with cement only. Meanwhile, for other replacement levels, the compressive strengths of concrete specimens were lower than control specimens.

Anoi Itam Beach (AIB), located in the eastern part of Weh Island, has the sediment characteristic of dark-sand color. Climatologically, the beach is influenced by two seasons, i.e., south-west (SW) monsoon and northeast (NE) monsoon. Sediment data are collected in the upper and lower littoral zones that are divided into six stations alongshore. Data were collected on October 2016 and April 2017, representing post (SW) monsoon and post-NE monsoon events. To examine the effect of seasonal, sediments statistics, e.g., mean, sorting, skewness, and kurtosis, have been calculated. AIB was characterized as well sorted to poorly sorted sediment. Sediments were identified as mesokurtic in October, varied to leptokurtic and platikurtic in upper littoral and lower littoral, respectively, in April. Grain size in both upper and lower littoral had increased from October to April. The impact on sediment sortation was minor due to the seasonal difference. Sediments in the upper littoral vary slightly skewed than lower littoral, which response to a more positively skewed during seasonal change from SW-monsoon to NE monsoon. The results suggested that lower littoral provide high variability of sediment characteristics depend on the season.

Gayo Lues District is known as Citronella and Arabica coffee producer in Aceh province, Indonesia. This paper aims to manage Citronella and Arabica coffee's land arrangement in the Gayo Lues District's cultivated area. This implementation is aimed at maintaining the peculiarities of citronella products and Arabica coffee. Thus, the two commodities must be separated in terms of allocated sites. The altitude for the area is 200-2,000 meters above sea level, consisting of ten classes, and the type of soils are Entisols, Oxisols, Inceptisols, and Ultisols. The area's slope between 0- to 40% (4 classes) was used to delineate the land units. There are 49 land units observed within the cultivated area of 160,017.17 ha. The guidelines for land suitability classification by the Ministry of Agriculture for Citronella and Center for Coffee and Cocoa Research, Jember for Arabica coffee were utilized. The results showed that 58,275.5 hectares of land were suitable for citronella, and 13,765.75 ha has been planted. The actual land suitability of citronella inside the area of 58,275.5 ha is suitable (S2 class) and marginally suitable (S3-class) and not suitable (N-class) with limiting factors are temperature, water availability, erosion hazard, and nutrient retention. This land suitability can be improved by providing inputs to increase the level of suitability with temperature, water availability, and erosion hazard (slope) limiting factors. Also, 48,765.3 hectares can be developed for Arabica coffee, and 4,653.5 ha has been planted. The actual land suitability for Arabica coffee is Suitable, Marginal Suitable, and Not Suitable, limiting the soil's physical properties (adequate soil depth), slope, and chemical properties of the soil. Once repaired, the land's suitability becomes Suitable (S1-class) (without limiting factor), Suitable, and marginal suitable with the slope as a limiting factor. There is an area of 44,509.75 hectares of land at 200-1,400 m above sea level within the cultivation area developed with a Citronella. There is an area of 44,111.8 ha at the height of 800-2,000 m above sea level, potentially for Arabica coffee.
