Urbanization is a common issue faced by many authorities. Urban population is steadily growing which requires more land for housing and other activities. Predicting urban growth pattern has been challenging efforts for planners. Many models have been developed by various researchers and practitioners to give a glimpse of possible future lookout of the city. This paper attempts to explain the basic of Bucket model, where new inhabitants will fill the more developed urban areas then spill over to less developed urban area and finally to rural areas bordering urban regions. This model is using a grid map as patches in the Agent Based Model (ABM). Each grid cell is filled with land use, population density, and other data to show its advantages compared to others. New inhabitants as the agent can move freely among the grid cells until an appropriate cell is found. Restrictions should be introduced to for each cell to limit the growth. This paper shows the initial idea of an urban growth simulation using ABM. Keywords: Urban Growth Model; Agent Based Model; Urbanization; Grid Map; Geographic Information System

Transit system had been proposed for the urban area of Honolulu. One consideration to be determined is the alignment of the transit system. Decision to set the transit alignment will have influences on which areas will be served, who will be benefiting, as well as who will be impacted. Inputs for the decision usually conducted through public meetings, where community members are shown numbers of maps with pre-set routes. That approach could lead to a rather subjective decision by the community members. This paper attempts to discuss the utilization of grid map in determining the best alignment for rail transit system in Honolulu, Hawaii. It tries to use a more objective approach using various data derived from thematic maps. Overlaid maps are aggregated into a uniform 0.1-square mile vector based grid map system in GIS environment. The large dataset in the GIS environment is analyzed and manipulated using SAS software. The SAS procedure is applied to select the location of the alignment using a rational and deterministic approach. Grid cells that are superior compared to the others are selected based on several predefined criteria. Location of the dominant cells indicates possible transit alignment. The SAS procedure is designed to allow a transient vector called the GUIDE (Grid Unit with Intelligent Directional Expertise) agent to analyze several cells at its vicinity and to move towards a cell with the highest value. Each time the agent landed on a cell, it left a mark. The chain of those marks shows location for the transit alignment. This study shows that the combination of ArcGIS and SAS allows a robust analysis of spatial data and manipulation of its datasets, which can be used to run a simulation mimicking the Agent-Based Modelling. This study also opens up further study possibilities by increasing number of factors analyzed by the agent, as well as creating a composite value of multi-factors.

Solid Waste Processing Technology at the Source (TOSS) is an alternative method in processing organic and biomass waste on a communal scale. The processing of organic and biomass waste material is carried out in three stages of the process: biodrying which utilizes the aerobic activity of microorganisms; chopping which is intended to refine the material, and pelletization to compact the material into biomass pellets. The biodrying process in bamboo boxes is able to reduce the water content in organic and biomass waste within 4-5 days. Sorting of non-organic materials can be done at an early stage before or after the biodrying process. Sorting is required before chopping and pelletizing process to avoid unnecessary machine break down. The biomass pellet which is the final product has a diameter of about 10 mm with a length between 10-40 mm, a calorific value between 3000-4000 kcal/kg, and a moisture content of up to 15%. Compared to coal, biomass pellets tend to have higher volatile and ash content, while lower ash and sulfur content.

Noise level in the classroom is a factor affecting the learning process. This study aims to determine the level of indoor noise of a private university campus in West Jakarta. Measurements were made using Sound Level Meter that can record the noise level every second with accuracy up to 0.1 dBA. Sampling was carried out in a number of classrooms in an empty condition, closed door, and air conditioning system either in off or on position. Classrooms are distinguished based on the condition of the wall, namely the window facing the outside environment and massive walls without windows to the environment. The measurement results indicate a significant difference in noise level at a 95% confidence level in an empty classroom when the air conditioning system is not functioning and when the system is running. Differences also occur in classrooms with and without windows to the environment. The difference shows that the classroom in an empty condition can experience an increase in latent noise level due to the operation of the air conditioner between 5.78-16.49 dBA. Increased noise from the environment including the highway is about 3 dBA for classrooms located on the 5th floor, with a horizontal distance about 100 meters from the highway and has thick and permanent glass windows.

Transportation is a sector that contributes significantly to CO2 gas emissions and has the potential to continue to increase along with the addition of fossil fuel vehicles. Indonesia has plans to switch to electric vehicles as an alternative to reduce greenhouse gas (GHG) emissions from the transportation sector. The battery is an important component of an electric vehicle, and there are several alternative technologies that can be used. This paper simulates the selection of a suitable battery from various type of batteries, including Lead-acid (PbA), Nickel Metal Hydride (NiMH) and Lithium-ion (Li-ion). The selection is made using the weighted objective method by presenting 5 criteria: energy density; emissions generated for battery production; energy factor of the manufacturing process; availability of critical raw materials required for cathodes and anodes; and availability of recycling facilities. Supporting data to determine the magnitude of each criterion is obtained from literature reviews. The analysis and comparison was carried out by giving weight to the assessment based on the data obtained. The results of calculations carried out in the paper show that the Lead-acid battery is a viable option for use at current time.However, if Indonesia already has NiMH and Li-ion battery recycling facilities, or is capable of producing Lithium-ion batteries, then the criteria and calculation factors can be added and improved.

Community Service (PkM) partner are located in Kp. Cipalahlar RT. 010/005 Sukaragam Village, Serang Baru District, Bekasi Regency, Jawa Barat Province. The Kp. Cipalahlar, although.it is surrounded by a residential area and not far from an industrial area in Bekasi, this village has received less attention from the Bekasi Regency Government, it can be seen the electrical cable network that is connected to the houses of the villagers is only put on trees and no electricity poles at all. So, it can be understood when in Kp. Cipalahlar does not have public street lighting facility (PJU) so when night comes the village becomes very dark. Therefore, to help residents get lighting at night, especially lighting on concrete roads, the community service (PkM0 team installed three public street lighting (PJU). The PJU is very useful for residents to carry out their activities at night such as going to the mosque for congregational prayers. The mosque will be lively with the presence of children to recite the Qur’an. The type of PJU installed is PJU based on solar cell panels because it is more practical and requires almost no maintenance in operation and has a long service life, up to 25-30 years.

Energi merupakan kebutuhan dasar manusia, yang terus meningkat sejalan dengan tingkat kehidupannya. Bahan bakar minyak/energi fosil merupakan salah satu sumber energi yang bersifat tak terbarukan (nonrenewable energy sources) yang selama ini merupakan andalan untuk memenuhi kebutuhan energi di seluruh sektor kegiatan. Kurangnya pemahaman masyarakat mengenai proses terjadinya energi listrik membuat mereka belum banyak melakukan penghematan energi listrik dalam kehidupan sehari-hari. Selama ini, sebagaian besar siswa dalam menggunakan energi listrik tidak memikirkan dampaknya terhadap kelestarian lingkungan hidup. Kegiatan sosialisasi energi baru dan terbarukan adalah merupakan upaya atau langkah yang dilakukan untuk mengurangi ketergantungan terhadap energi fosil dan sekaligus menjaga kelestarian lingkungan. Kegiatan ini merupakan kegiatan sosialisasi yang dimotori oleh para dosen STT-PLN untuk memberikan edukasi kepada masyarakat tentang pentingnya memahami penggunaan energi listrik secara bijak dalam upaya menjaga lingkungan.
