Abstract
The purpose of this research was to develop and study the results of the implementation of the Learning Management Process for Inculcating 12 Principal Values with the Sustainable Learning Concept for Secondary Schools. The samples were composed of academicians, experts, administrators, teachers and students from six regions of Thailand in the academic year 2017 – 2018. The study design used the research and development methodology with the integration of survey research, experimental research and action research, according to research that combines both quantitative and qualitative aspects. The results of this research were: 1. The Learning Management Process for Inculcating 12 Principal Values with the Sustainable Learning Concept for Secondary School having the manual process of learning to reinforce the core values are based upon the concept of learning to sustainability for secondary school. The process of learning in essence consists of three lesson plans for all 11 study plans including the following: 1) The Learning Activities consisting of honesty, sacrifice, and patience; 2) The Learning Activities are aimed at pursuing two courses of Persistence of Learning Activity; and 3) The Learning Activities consisting of seeking sufficiency. The results of the Trial Process and the Learning Development with 50 Grade 8 students at Angthong Pattamarot Wittayakhom School found that the teacher can implement learning management in planning and students shared satisfaction in the learning processes. 2. The results of the Learning Management Process for Inculcating 12 Principal Values with the Sustainable Learning Concept for Secondary Schools were to develop the testing efficiency of the process of learning to reinforce the core values for 4 regions, namely: Central, North, South, and East. The teachers had planned activities scheduled but had to improve the group of students due to the relatively short duration of the trial and the assembly time of the students in the regular class schedule and the regular activities of each school. The Trial Process was the solution by dividing students into three groups and carrying out activities while simultaneously adjusting all three events planned in the activities by the 4 school teachers at the start of the Orientation Objectives for the students. They had the opportunity to ask questions and to understand the activities as assigned. Among the activities carried out by them, the teachers had to follow the progress of a 4 week period until the deadline. The results that in Activity 1( honesty, sacrifice, patience) and Activity 2 (focus on learning and trying to learn) students can perform their activities according to the prescribed curriculum and did not find any problems or obstacles. Especially in Activity 2, the Students learned the knowledge. Notes were recorded continuously summarizing the knowledge of the students. It also showed that knowledge is applied in the daily life of students, as well as activities in the three seeking sufficiency activities broken into three parts: 1) Recorded Income 2) The vegetable garden fence sufficiency and 3) Garbage Bank. The result of data analysis of the of 194 students from all 4 secondary schools showed the students satisfaction to learning management activities were satisfied at the high level. The assessment of testing the efficiency of the Learning Management Process of the 12 Principal Values with the Sustainable Learning Concepts for Secondary Schools in 4 regions namely Central, North, East and South were evaluated by 23 experts and teachers. Their opinion was that the learning levels were high and most high overall and in various aspects, including: 1) the use of information technology in the development of effective teaching, 2) the nature of flexible learning content and links and continuity in terms of efficacy, creativity, morality and ethics, and 3) teaching that focuses on the learning process, analytical thinking, the group processes, process skills, and 4) the adoption in developing better features for all sex, ages, and class levels of learners.

Abstract
The micro-cracks that commonly occur in concrete structures are a potential source of crack propagation which leads to the possibility of catastrophic failure. Concrete cracks that occur propagating mainly along the interface zone that significantly conditioned by aggregate characteristics. Aggregate characteristics as concrete fillers have a significant role as a strain energy release medium known as fracture energy. This research is using an experimental investigation about the fracture characteristics of concrete using different gradations with a maximum diameter of 25 mm and 20 mm. The experiment includes a compressive strength test and a fracture parameter test. Three-point bend test was selected based on RILEM recommendations to calculate fracture parameters. The result has shown that the aggregate gradations used in concrete mixtures should take into account the effect on compressive strength and total fracture energy.

Abstract
Nowadays, the climate change has resulted in extreme weather events. This change happens because of the effect of global warming. One of the main factors is the carbon emissions that have exceeded the permitted limits. Many countries in the world have taken a significant action by making some commitments to fix it. One of the commitments is to give a penalty for the cost of emissions produced by a country or company. In this study, we developed an integration model between inventory and multimodal land transportation by focusing on the costs of emissions produced. To distribute products from several suppliers to several consumers, we proposed train as long distance transportation mode and truck as short distance transportation mode. The purpose of this study is to find the best solution for total system costs. The total cost consists of operational costs and emissions costs. From numerical experiments, the carbon tax rate affects the amount of carbon emissions and the total cost. The trade-off between emissions and costs will produce an optimal solution. In addition, it can be seen the impact of tax to the other decision variables such as inventory and transportation. The method used in finding the optimal condition is Mixed Integer Linear Programming.

Abstract
Biogas production from various organic wastes such as corn stover can be used as an alternative fuel. Corn stover is one of the agricultural wastes that are widely generated in Indonesia. It contains cellulose which has the potential to be used as raw material for producing biogas. The biogas production process was carried out in solid-state anaerobic digestion (SS-AD), i.e., a biological process that occurs naturally by a microorganism that breaks down molecules of organic material with a total solid content greater than 15%. This research aimed to investigate the effect of EM-4 concentration on biogas yield. The volatile solids (VS) reduction was also measured in this study. The results of the study showed that EM-4 concentration had a significant effect on biogas yield (p < 0.05). The positive linear relationship was found between EM-4 concentration and biogas yield. The highest biogas yield of 597.98 L/kg VS was obtained at EM-4 15%. The main source of biogas production during SS-AD of corn cob was the reduction of VS.

Abstract
Failure of concrete in the environment which containing sulphate causes damage to the cement bonds in the concrete. One of environment that contains sulphate is peatlands. Peat water has a low acidity (pH) and causes the water to be acidic. The acidic environment will slowly damage the concrete starting from the edges and corners of the concrete with the release of granules of concrete particles so that the concrete becomes porous. To reduce the damage, used mineral additives in the form of Ground Granulated Blast Furnace Slag (GGBFS) on Type II Cement. The purpose of this research was to determine the effect of using variations of GGBFS as an additives on Portland Cement Type II on compressive strength of high quality concrete and the optimum variation percentage using GGBFS as additives on Portland Cement Type II. This research outlines divided into several stages, i.e. material testing, manufacturing of test specimens, testing of test specimens and analysing test results. This research used a cylindrical specimen with 4 variations of the mixture that is normal concrete, concrete with the addition of 2 % ,4%, and 6% GGBFS by the weight of cement with a concrete age of 7, 14, and 28 days. Also, the treatment of specimens is carried out using peat water. From the results of this research, it can be concluded that the effect of using a GGBFS addition as an additives can increase the compressive strength of concrete from normal concrete, however it decreases with the addition of 2% GGBFS and 6% GGBFS at the age of 7 days amounting to -14.62 % and -3.47 %. The optimum variation percentage is concrete with the addition of 4% GGBFS which produces compressive strength of 40.90 MPa and the minimum variation is concrete with the addition of 0 % (normal concrete) which produces compressive strength of 33.82Mpa.

Abstract
Subgrade is part a road pavement structure designed to accept vehicle loads on it. Therefore must have an optimal carrying capacity and be able to accept the load due to traffic without experiencing significant changes or damages. The increase of heavy vehicle passing the main road cause damage on the pavement surface, such as rutting. For this reason, soil improvement is needed in order to obtain a stable subgrade to increase the performance of the pavement structure. The effort of stabilizing the subgrade soil of expansive clay has been conducted by various stabilizer, such as limestone, cement-fly ash, pozzoland material and others. One of stabilizer materials that can be used as an additive material is phosphoric acid, meanwhile other alternative material for phosphoric acid mixture is coconut shell ash. Soil sample is taken from Gedebage region and the test result on the soil is categorized as expansive soil category. In a soil stabilization with the mixture of 8% coconut shell ash + 10.5% phosphoric acid within 0 day of caring period can increase the carrying capacity of the soil and reduce damage due to fatigue cracking and grooves (rutting) which can improve the performance of flexible pavement structures.

Abstract
The potential of bamboo as one of the materials that have a high tensile strength of parallel fibres is expected to be an alternative material to replace steel reinforcement. It is very feasible to use because bamboo is a renewable resource, cheap, easily cultivated, relatively fast growth, and the use of bamboo can play an important role as a first step in realizing savings of renewable resource. This research will develop bamboo as reinforcement which is applied to the structure of reinforced concrete beams by making modifications that utilize as much as possible the strongest part of bamboo, namely on the skin. The specimens were designed in the form of reinforced concrete blocks with dimensions of 200 x 400 x 1700 mm, with 2 bars of compressive reinforcement and pulling 3 D13 rods while imperfectly shaped bamboo stirrups with dimensions of 12 x 12 mm. In the modification made on bamboo reinforcement, there are 2 types of reinforcement, namely bamboo reinforcement using 1-inch screw nails and bamboo reinforcement using 1½ inch screw nails, while the distance between screw nails is taken at 75 mm. Reinforcement area there is 4 strain gauge.

Abstract
The number of urban population in Indonesia increased about 0.7% per year (2015-2019). Likewise Bandung City, it grows around 0.43% per year.
