Abstract
Final Project Electrical Engineering Students at Bandung of State Polytechnic is a compulsory subject of 6 credits. It consists of the student undertaking an autonomous project under the direction of an advisor, the completion of which is intended to help the students implement the skills that they have gained during their studies and ensure that they acquire the relevant competences associated with their degree. To manage this activities is complex and time consuming for students, advisors, and committee. The final project process starts from proposed final project students, evaluation them, advising, reporting, and examination. To manage it, web based application that nowadays is very popular is applied. So, this paper presents the Final Project Student MIS Application web platform designed for Electrical Engineering Department students and their lecturer. The system is called SePaKaT TA (Sistem Pengambilan Keputusan Terpadu Tugas Akhir). The process of implementation of the system is based on the Waterfall Method that is a breakdown of project activities into linear sequential phases, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. The approach is typical for certain areas of engineering design. The Final Project Student MIS Application is a best solution because it-s support on time correctly without delays and informing online all students. In addition, the system provides with Decision Support System (DSS) to decide students eligible for examination based on requirements. Other advantages of the system is less paper usage and less people to manage

Abstract
The development of industry causes energy needs to increase. So that fossil energy reserves are increasingly depleting. This resulted in the growth of various alternative energies. One alternative energy that is being developed is biomass-based energy. Biomass is a renewable energy source that comes from plants both directly and indirectly. Indonesia is a country with a tropical climate that has a very large biomass potential. One of the methods that can be used in processing biomass is gasification, which is a process to convert solid biomass raw materials into fuels (syngas). The problem from the gasification process is the syngas produced has a low purity level. This is because there are still impurities that are contained in syngas. Therefore, a purification unit is needed in the gasification device. This research aims to make absorbents that can be used in gasification purification units. The types of absorbent used is coconut shell activated carbon. The pore structure of carbon is characterized by using an N2-sorption analyzer (Nova 2000, Quantachrome). Based on the results of characterization, it can be seen that the specific surface area of activated carbon absorbent from the coconut shell is 1320 m2/gram with an average pore diameter of 1.82 nm. The experiment device mainly consisted of gasification reactor, filter, and blower. The gasification reactor was installed to heating the biomass with the supply oxygen. The reactor had a height of 170 cm and a diameter of 50 cm in which the bagasse with the capacity of 15 kg/h was quickly burned. The gas filter contains the absorbent to clean the syngas product. The absorbent was installed in upper four holes. The blower was used to suck up the syngas. Some thermocouple and gas indicator were installed to monitor the condition in the system. The syngas production was analyzed by the GC/MS analysis. The effect of absorbent is to improve the syngas composition such as CO, H2, and CH4. The syngas contents in our experiment were CO, CH4, and H2 with a percentage of 9.294%, 1.348%, and 7.773%, respectively. These results are better than the previous research with the syngas contents are 7.891% of CO, 0.100% of CH4, and 0.889% of H2 because the previous research was not equipped the absorbent.

Abstract
Urban societys health is directly affected by environmental factors where the quality of the environment is decided by the development of urban infrastructure. Exponential growth of population in Metropolitan Cities without being matched by basic sanitation supplies will raise the deteriorating environmental conditions. Bandung metropolitan city has a high level of urbanization so that the problem of basic sanitation supply is more important. This study aims to identify sanitation problems and efforts to improve access to basic sanitation in Bandung city. This research method uses a deductive approach with quantitative and qualitative mixed analysis methods. The use of data in this study uses secondary data from the past 5 years. Our initial synthesis shows that the main problems of access to basic sanitation in Bandung are caused by technical constraints in the form of lack of suitable land and limited access to the PDAM sewer, while non-technical constraints in the form of readiness and understanding of local urban society, and budgeting. The efforts of Bandung city are currently quite massive, but the improvement of sanitation access is still not significant.

Abstract
Glycerol is widely use in the production of cosmetics, solvents for drugs, and lubricants. Glycerol can be obtained as by-product of biodiesel production from vegetable oils through the transesterification process. One of the vegetable oils with abundant raw material availability in Indonesia is corn oil. Each vegetable oil generally consists of triglycerides and free fatty acids (FFA) with different composition. The triglycerides in corn oil is round 95.59% (mostly trilinoleate and triolein), the rest are FFA (2.51%), phospholipid and phytosterol. The simulation process was designed using Aspen Hysys version 8.8. The corn oil composition was simulated as 54.30% trilinoleate, 41.35% triolein, and 3.85% oleic acid (FFA). The mole ratio of corn oil : methanol was set to 1 : 20. The transesterification process was simulated using conversion reactor with conversion 98% at temperature 60C and atmospheric. The process was followed with methanol recovery and glycerol separation from biodiesel. From the process around 84.5% of excessed methanol was recovered. Glycerol and biodiesel were separated using membrane. The simulation indicates that 100 kg/h corn oil can converted into 101.1 kg/h green diesel and 10.41 kg/h glycerol with purity 99.85%.

Abstract
High demanding of tofu as a food type containing high protein-s source in Indonesia is followed by increasing amount of tofu waste produced from this industry, both solid and liquid waste. The high amount of organic material of this wastewater (9,880 mg COD/L) results in its potential to be treated biologically by the combination of the anaerobic-aerobic process. To enhance the process efficiency and better quality of the effluent, in this study, coagulation and flocculation process was added as the finishing process after biological treatment methods. The purposes of this research were to evaluate the more effective method between aerobic process and the combination of anaerobic-aerobic process and to determine the best dose of tamarind seed as the natural coagulant. Doses variant used were 1,000 ppm, 2,000 ppm, 3,000 ppm, and 4,000 ppm. The result showed that the aerobic process had a slightly better performance of COD removal compared to the combination process (anaerobic-aerobic), which was about 89.744%. The finishing process, coagulation and flocculation was focused on lowering turbidity level of the effluent of biological process. 2,000 ppm of tamarind seed gave the best result on decreasing turbidity level for both processes, aerobic process (63.745%) and anaerobic-aerobic process (47.567%).

Abstract
Soil erosion is a problem that often occurs in watersheds. The results of erosion will enter the river as sediment. The amount of erosion and sediment are parameters that describe the critical level of a watershed. Cipunagara watershed is one of the most critical watersheds in Indonesia. Therefore we need a study of sediment control due to erosion and sediment. This study aims to determine the level of erosion in Cipunagara watershed, find out sediments in Cipunagara River, and determine the sediment control structure that can be applied in Cipunagara River. The method used in this research is quantitative descriptive method with modelling on SWAT. The analysis was performed using secondary data in 2005-2014. Modelling in SWAT divides Cipunagara watershed into 33 Sub Watersheds. The highest erosion value during years data occurred in Sub-watershed 18 of 654,402 tons/ha/ year with very severe erosion criteria and the lowest in Sub-watershed 5 of 1,075 tons/ha/ year with very mild erosion criteria. The highest sediment value is in River 25 which is 1754758.30 tons/year, and the lowest in River 7 which is 7174.40 tons/year. Sediment control in Cipunagara watershed can use check dams that place on River 18 and River 25.

Abstract
This paper aims to provide an overview of the complicated problem of skilled workers in the construction industry faced with the demands of worker-s certification. The skilled workers in question are the ones at the construction sites or known as construction workers. The number of group of workers continues to increase every year along with the increasing quantity of the countrys construction industry development. However, of the more than 8.3 million construction workers spread across various construction projects, only 7.4% are certified (Ministry of Public Works and Housing, 2019). This study used descriptive qualitative methods with interview techniques, Focus Group Discussion (FGD), and content analysis. It was found that there was a large gap between the demands of modern industry on construction workers and the prerequisites for skills certification. This had become a major problem in the employment system in the construction industry. Among the contributing factors are the traditional work culture, lack of knowledge and information about worker certification, institutional certification system, difficulty of access to education and training, and challenges to gain recognition as indicated by increased welfare regarding minimum wages.

Abstract
Practicum is an essential component in the learning process at universities, especially in the fields of science and technology. Realizing quality practicum requires a balanced amount of equipment that supports the process, but practicum participants often exceed practicum equipment. The solution is to create a remote laboratory that can be accessed from anywhere while connected to the internet. Remote laboratory consists of three important parts, namely a server that consists of a computer or laptop connected to the data processor sent by the user and then connected to the actuator, a server is also connected to the camera that the user can observe the practical work. The second part is an internet connection, and the third part is the user. All that is controlled by ThinVNC software, ngrok, and GUI that has been provided. On the server computer, GUI, ThinVNC, and ngrok are installed as controllers for the practical work, while the user can open the website to access the lab computer. Based on theory and experience, this technique is very suitable if used in PLC and pneumatic practicum. The use of remote labs makes students more skilled in facing the era of the industrial revolution 4.0.

Abstract
Virtual laboratory is a facility that allows access to laboratory equipment from anywhere and any time while connected to the internet. Remote desktop systems are the basis of the development of virtual laboratory where users can access equipment connected to the lab computer from anywhere with the agreed time. The virtual laboratory can overcome the problem of the imbalance of the number of tools available in the lab with the number of students who will do the practicum, especially the PLC, HMI, and hydraulic simulation. For accessing the lab computer, this tool uses web-based HTML and VNC (Virtual Network Computing) techniques. On the server computer, the ThinVNC server is installed, and the user, password, and port are set. ThinVNC functions as a tool that makes it easy for users to access the lab because it simply provides a web browser that supports HTML 5 such as chrome, firefox and edge without having to install any browser plugins and does not need to install RDP, so tablet or smartphone can access the lab. When it is connected, user can access the available lab equipment and can see the results made because there are cameras that monitor the course of the practicum.

Abstract
Reclamation in the former mining area is a series of ongoing activities with planned post-mining activities, so that the reclamation activity plan is adjusted to the post-mining activity plan. However, a lot of ex-mining land at this time, especially abandoned tin mine in Bangka Belitung Province is not well covered so it does not meet the applicable post-mining rules. Planning for reclamation of ex-mining land that has been abandoned or that has been re-mined by the community is a challenge to represent a concrete manifestation of sustainable management in the Indonesian mining sector, which refers to Government Regulation No. 78 of 2010 and the Minister of Energy and Mineral Resources Decree No. 1827 2018. Preliminary investigation of the condition of the land to be reclaimed is done by using a "drone", so that data collection can be done quickly and can present the original condition. "Drone" equipment is equipped with the concept of photogrammetry so that the results can be used for topographic map making. Some factors that need to be considered in the reclamation of alluvial tin mining are geological hazards, hydrological, hydrogeological, re-mining and monitoring. With good data from these aspects, good engineering can be carried out to realize the reclamation of the land of the former alluvial tin mine that is sustainable.

Abstract
The remote laboratory system allows users to conduct lab work via a remotely controlled lab computer. Each computer has a different interface to interact with the operating system. This affects the users comfort and effectiveness in accessing the remote laboratory. Based on this, we need a support system in the remote laboratory to maximize user time in practicing. The interface on the computer lab becomes an essential factor in supporting a practicum that uses computers. GUI (Graphical User Interface) is an interface that allows users to interact with the operating system or computer graphically. In contrast to the CLI (Command Line Interface), which uses the command line, the GUI uses a graphical menu, allowing users to more quickly and more efficiently interact with the operating system. The main features of the GUI are made up of three components. The components in question include time management features, application selection, and notifications. If the GUI is connected, users can easily open applications provided by the computer server. Intended uses include the CX-Programmer for Programmable Logic Controllers (PLCs), Pneumatic Pneumatic Festo, and cameras. In addition, the GUI also functions as a practical timer and notifies the user. This can be seen from the closed and automatic connection disconnection between the user and the computer server if the practicum time is up.

Abstract
A specially designed low speed generator has been developed in order to be used on low speed turbines. The axial flux permanent magnet (AFPM) generator type was chosen to meet these needs. The generator consists of a stator and a rotor. To determine the characteristics of the AFPM generator, we conducted a study of the effect of the distance between the stator and rotor, and the effect of rotational speed on the output voltage. The stator armature was made of copper wire with a diameter of 0.2 mm. The number of turns of a winding was 200 turns which produced a resistance of 100 ohms. The shape of the armature was adjusted to the shape of the magnet. The rotor disc was occupied by 18 magnets arranged symmetrically. The size of the magnet was 50 mm long, 30 mm wide and 10 mm thick. The laboratory test was conducted by placing the rotor ranging from 23 mm to 15 mm, with changes in distance of 2 mm each, from the stator. From the measurement, the linear equation of output voltage vs rpm curve was obtained as well as the output vs stator-rotor equation. From the result, it can be seen that increase of rpm and the closer the rotor-stator distance, the higher the output voltage.

Abstract. Foods that are starting to have a high demand by consumers are food that not only have good appearance and taste, but also have a functional functions. One of Indonesian functional product is tumeric and tamarind extract, however, this product have low sensory reception. Dark chocolate is one of the functional foods that have a high sensory reception, these products can be combined to get functional food with good sensory reception, the author chose to made them into Belgian Praline. The purpose of this study was to analyze differences in the level of preference of Belgian Praline products with various concentrations of tumeric and tamarind filling. The study was conducted using the CRD (Complete Randomized Design) the number of treatments (t) was 3 with 2 repetitions (r). The procedures and formulas is done by prescribing the results of consultations with traditional panelists, consultation is carried out 3 times, making 3 basic formulas and procedures. ANOVA and Duncans test result show that the level of preference for the three research products showed different results.

Abstract
Computer laboratory is an important facility that must be owned by vocational high schools to support the teaching and learning process, especially on practical lessons. Some practical assignments require students to operate computers in order to complete assignments and search various sources of information from the internet. The aim of this study was to determine the availability of computer laboratory facilities and the design of computer laboratories available at vocational high schools. Data collection uses observations and interviews. Researcher interviewed several teachers in vocational high schools to explore information on the availability of supporting facilities and infrastructure in schools for people with physical disabilities especially in computer laboratories. Researcher also interviewed two special school teachers to explore information about the needs for facilities and infrastructure for people with physical disabilities, their experiences when observing and activating with students with disabilities. The results of this study indicate the unavailability of infrastructure facilities that are friendly for people with disabilities especially computer laboratories in vocational high schools. The conclusion of this study recommends that schools make improvements and additions to facilities that support students with disabilities, especially those with physical disabilities, so that they are able to carry out activities like normal students when accessing facilities and infrastructure at school.

Abstract
Introduction: On September 28, 2019, there was an earthquake followed by liquefaction, landslides and tsunamis in Palu City, Donggala and Sigi Regencies. Disasters cause many victims and health problems. Diarrhea and dysentery were influenced by the worsened of environment and sanitation caused by disaster. Methods: Qualitative research with indepth interviews to officer of Central Sulawesi Provincial Health Office, officer of Sigi District Health Office, Head of Puskesmas. Respondents must cite operational evidence based on direct experience. Analyze results with qualitative content. The study was conducted in February - March 2019. Results: an increase of diarrhea cases from 1.76x to 4.1x after the disaster. No cases of dysentery were reported before and after the disaster. Projections of WASH disorders and diarrhea occur up to 12 months after the disaster. Dysentery are not projected as a health problem. There were increasing of refugees in the first week after the disaster from 15000 to 93000 after 4 months. There were increasing of refugee camps from 10,000 to 90,000. The number of refugee vulnerable groups is 46,961 and 57.51% of infants and children. Conclusion: There was an increase in diarrhea and WASH disruption cases in Sigi district, but no cases of dysentery were reported before and after the disaster. This relates to the number of places of refuge that is less than the number of refugees, the high percentage of vulnerable groups of infants and children.

Abstract
Vehicle generally require an optimal braking system, eddy current brake (ECB) can be used as an alternative to the conventional braking system. Unipolar Axial ECB was discussed in this paper. Performance of ECB is influenced by several factors, like the distance of the pole location to center of the shaft. The pole location determine the braking torque because the change of braking force arm. In this paper, finite element method (FEM) based modeling are used to describe the eddy current change. Size and design of ECB are based on a conventional hydraulic braking system. The standard pole location will be similar to the brake pad on a conventional hydraulic braking system. The pole location will be varied to profile the changes in braking torque. From data, it was found that the pole location near than standard tends to have good braking torque at high speeds. In reverse, at low speeds it has lower braking torque compared to standard pole location. Then at the pole location far than standard give the resulting braking torque is lower in both while low speed and high speed. It is because the eddy current turn path area become narrow on the rotor when the pole location far from standard.

Abstract
According to International Diabetes Federation, Indonesia ranked 6th in country with highest diabetes patient in the world. Now, the measurement of blood glucose in Indonesia mostly done in invasive manner, which is expensive, painful, and impractical. Moreover, according to Indonesia-s Ministry of Health, there are more diabetes patient in rural areas, who have economic shortages and limited access to health care. So, a cheap and easy to use non-invasive blood glucose measurement system is needed to solve this problem. One of the current trends for developing non-invasive blood glucose measurement is the use of Near-Infrared Spectroscopy (NIR). In this paper, we discuss the development of a NIR based blood glucose monitor. The device-s sensor consists of a pair of LED and photodiode which transmit and receive light with wavelength of 940 nm. The light intensity reading from the sensor will be amplified and filtered to reduce noise, then transmitted to the smartphone. In the smartphone application, the reading result will be converted to blood glucose level using a machine learning model embedded in the application. The model used in this final project is a sequential, layer-based neural network model provided by Keras. The model was built and trained on top of TensorFlow, and then converted for mobile use with the help of TensorFlow Lite. The model achieved an acceptable result with Mean Absolute Error (MAE) of 5.855 mg/dL.
