Abstract

The purpose of this study is to describe the process and results of developing a Hydraulic Hot Press machine for molding areca palm sheath sheets into tote bags. Areca palm sheaths were selected as the sample material due to their abundance as organic waste in Sambas Regency, which has not yet been utilized in waste processing. This research was conducted through five stages: literature review, tool design, preparation of tools and materials, fabrication, and testing. The development process of the Hydraulic Hot Press included determining the dimensions, constructing the frame, assembling the heating system, and conducting functional tests. The press was designed with dimensions of 100 cm in length, 60 cm in width, and 130 cm in height. It was equipped with a heating system powered by an LPG gas cylinder as the main energy source, with heat delivered through a piping system to the main pressing point. The results indicated that when the steel base plate of the press was subjected to hydraulic pressure and direct heating, thermal expansion occurred, causing slight bending of the steel foundation. This condition led to less-than-optimal molding results of the areca palm sheath sheets into tote bags.

Abstract

Waste refers to residual materials resulting from various human daily activities or natural processes that exist in solid form. In general, the term waste denotes unwanted materials or substances considered to have lost their usefulness after a certain activity or domestic process has been completed. To date, waste management efforts in many regions have not yet achieved optimal results. The level of public awareness and concern regarding environmental issues related to waste also varies significantly, making this issue an urgent environmental challenge that requires immediate attention and solutions. This study focuses on testing the effectiveness of waste treatment methods through the combustion process. The main objective is to determine the concentration levels of carbon monoxide (CO) and other hazardous gases generated during combustion, as well as to evaluate the performance of a waste incineration machine designed to produce low-smoke emissions. Gas concentration measurements were conducted using gas detection sensors integrated with an Arduino-based microcontroller system. The research approach combines both qualitative and quantitative methods. The qualitative aspect involves reviewing and comparing previous research findings, while the quantitative approach is carried out through direct measurements using a self-designed measuring instrument. This study is part of an ongoing research program aimed at developing a Low-Smoke Waste Incinerator Machine. Preliminary results indicate that the effectiveness level of the waste incinerator remains relatively low. This condition is attributed to the high concentrations of harmful exhaust gases such as carbon monoxide (CO), nitrogen oxides (NOx), and sulfur dioxide (SO₂) produced during the combustion process. In addition, the design of the incinerator has not yet reached optimal efficiency, as reflected by the persistently high NOx and SO₂ emissions. Therefore, more precise calibration of the gas sensors is required to ensure that the measurement data obtained accurately represent the actual concentrations of combustion gases.

Abstract

Kebutuhan akan sumber energi yang ramah lingkungan mendorong pengembangan bahan bakar alternatif berbasis biomassa, salah satunya biodiesel. Pemerintah Indonesia telah mentargetkan penerapan campuran biodiesel hingga B40 sebagai bagian dari strategi transisi energi nasional. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan bahan bakar campuran biodiesel 40% (B40) terhadap konsumsi bahan bakar dan emisi gas buang pada mesin diesel tipe common Rail Direct Injection(CRDI) dibandingkan bahan bakar solar murni (B0). Pengujian dilakukan menggunakan variasi putaran mesin 800, 1500, dan 2000 rpm, dengan pengukuran parameter Fuel Consumption Ratio (FCR), dan emisi gas buang (CO, CO₂, NOx, dan O₂). Hasil penelitian menunjukkan bahwa penggunaan B40 menyebabkan peningkatan konsumsi bahan bakar sebesar 5–10% akibat nilai kalor yang lebih rendah, namun daya keluaran mesin tetap setara dengan B0 karena sistem injeksi common rail mampu melakukan kompensasi tekanan secara adaptif. Dari aspek emisi, B40 menghasilkan penurunan emisi CO hingga 30% dan penurunan NOx sebesar 15–20%, disertai dengan sedikit peningkatan CO₂ akibat pembakaran yang lebih sempurna. Kandungan oksigen residu (O₂) pada gas buang B40 sedikit lebih rendah dibandingkan B0, menandakan pemanfaatan oksigen biodiesel yang lebih efisien dalam proses pembakaran. Hasil penelitian menunjukkan bahwa mesin diesel tipe common rail mampu beroperasi secara stabil menggunakan bahan bakar B40 tanpa modifikasi sistem, sekaligus menghasilkan profil emisi yang lebih bersih dan efisiensi pembakaran yang baik.

Abstract

Leg prosthetics support the mobility of people with disabilities. Designing economical leg prosthetics is a major challenge for increasing accessibility for disabled people because the majority of them are from low income economy. Technically, the challenge is to make a cheap buat light weight prosthetics. Low cost metal raw material of prosthetics are often inversely proportional to the weight of components. One of the cheap materials, i.e. steel has a specific gravity 2.9 times higher than aluminum, which is lightweight but twice as expensive. This study examines the structural integrity of ankle prosthetic base components made of steel and aluminum when subjected to dynamic loads of the human body in a single step, using finite element method numerical computations. The goal is to determine whether the type of cheap material will be reliable in bearing the load. The computational results show that inexpensive materials such as mild steel and aluminum 6061 are able to support the mechanical structure of ankle prosthetic model to remain rigid while handling dynamic loads. The working stresses of both materials are still within safe limits, able to bear the load, even when multiplied by safety factor, the stresses are still below the yield stress value of each material. Aluminum 6061 is recommended for the production of lightweight versions of prosthetic models due to its maximum deflection that is really small as low as 4.41 x 10-3 mm, while mild steel is for the low-cost versions. Validation of the computational results was carried out using comparative literature data. Contact pressure value of 3 MPa from this research is in accordance with literature.

Abstract

The concept of green building emerged and has been promoted as a solution to reduce the impact of carbon footprints. It has evolved into an integrated approach to environmentally friendly and sustainable building design, construction, and operation. The objective of this study is to evaluate the implementation of green building principles, assess the level of achievement in meeting green building criteria, and provide recommendations for improvements to help buildings meet the standards set by the Green Building Council Indonesia (GBCI) through its Greenship rating system. This research employed methods including observation, interviews, and measurements, with the results analyzed using a descriptive approach. The assessment of Building X in Bandar Lampung revealed that it scored only 10 out of a maximum of 20 points (equivalent to 45%) for the Indoor Health and Comfort category, and 16 out of a maximum of 36 points (equivalent to 44.4%) for the Energy Efficiency and Conservation category. To improve the green building performance scores, several measures can be undertaken. These include the installation of monitoring instruments for temperature, carbon dioxide, and carbon monoxide levels; indoor air quality assessments; optimization of lighting systems; formation of an energy cluster team; enhanced energy efficiency and conservation strategies; the use of renewable energy sources such as solar panels; and the provision of sub-metering (kWh meters) for ventilation, lighting, and other electrical systems.

Abstract

Suboptimal household waste management remains a problem in various regions. Waste is generally disposed of in landfills (TPA) or burned openly, both of which have negative impacts on the environment. Open burning of waste produces air pollution in the form of carbon monoxide, dioxins, and fine particles that are harmful to health. Therefore, this study aims to design and manufacture a portable, smoke-free waste incinerator as an alternative solution for independent waste management. The research methods used include literature review, design using CAD software, component fabrication, tool assembly, and functional testing. This tool is designed with a combustion system in a furnace with controlled air flow to optimize the combustion process and reduce smoke emissions. The result of this study is a prototype of a portable waste incinerator that is easy to move. Based on the results of functional tests and visual observations, this waste incinerator can burn dry leaves, with the condition that there is still quite a lot of smoke at the beginning of the combustion and the smoke puffs are significantly reduced as the flame grows.

Abstract

This research was conducted as an effort to overcome the problem of domestic waste in Karang Mukti Village, Cipeundeuy Subang. This is to realize community self-sufficiency at the village level in managing waste independently in a better and more efficient way. The initial step, this research focuses on the design and manufacture of a prototype of a waste burner (Incinerator) that can be operated without using fuel (self-burning) and the combustion chamber suhue is designed to reach more than 800oC. With the self-burning system in this incinerator design, it is expected to save operational costs because it will be operated in the village level area. The combustion system utilizes the heat from burning the waste itself (self-burning) with a combustion chamber design lined with heat-resistant walls from materials with good insulating properties, namely refractory bricks. The air flow entering the combustion chamber is generated from natural draft by determining the diameter and height of the chimney. Based on the design results, the Incinerator has a height of 2,000 mm, a length of 1,200 mm and a width of 1,200 mm. The chimney has a diameter of 200 mm and a height of 6,000 mm. Based on the results of domestic waste combustion tests, the lowest suhue in the combustion chamber was 306oC and the highest was 1,100oC. The lowest combustion capacity was 60 kg/hour and the highest was 255 kg/hour. Suhue fluctuations in the combustion chamber and combustion capacity are greatly influenced by the mixture conditions and humidity of the domestic waste fed into the combustion chamber.

Abstract

This research discusses the optimization of Platformer Heater design on PT platforming units.X with additional Sweet Naphtha processing capacity. The main objectives of optimization are toincrease energy efficiency, maintain reaction temperature stability at an optimal level, and overcomelimited heating capacity which has the potential to cause operational problems such as flameimpingement and overfiring. The research method includes Platformer Heater efficiency analysis andheat duty calculations carried out using Microsoft Excel. The operational data analyzed shows that theheating power requirement (Total Required Heater Duty) for the five interheaters has increasedsignificantly after the after conditions compared to the before conditions. The efficiency of eachinterheater is in the range of 70% to 72%, while the efficiency of the Platformer Heater is in the rangeof 70% to 80%. Even though efficiency between devices is relatively stable, this increase in heatingpower requirements indicates an increase in workload or changes in operational conditions that requirethese devices to use more power to continue functioning optimally. For example, interheater 2 requiresheating power of 139,967 Btu/hr in the before condition, which then increases to 221,614 Btu/hr in theafter condition. This confirms that changing conditions affect the amount of energy required for heating,so it is important to consider this in planning and operating the heating system so that efficiency andperformance are maintained. This study also emphasizes the importance of controlling Mean BeamLength and gas emissivity as key factors in increasing heater efficiency. Economic evaluation based onTotal Capital Investment and Operating Cost.

Abstract

The reduction of carbon dioxide emissions, or decarbonization, across all sectors must be carried out seriously. One of these sectors is transportation, through the implementation of an electric vehicle (EV) ecosystem by converting fossil-fuel-powered motorcycles into electric motorcycles. This study aims to design and analyze the performance of a 2 kW mid-drive BLDC motor in an electric motorcycle conversion application. The transition to electric vehicles requires conversion components, such as a BLDC motor. A collaborative research project with an industrial partner, PT X, focuses on the design and modification of a 2 kW mid-drive type BLDC motor. The design process was carried out by varying the gear ratios of 0.68, 0.72, and 1.34 to obtain an electric motorcycle conversion speed suitable for urban road use. Dynotest results indicate that the gear ratio variation of 0.68 provides the best performance using 30T and 20T gears. The maximum speed achieved under this configuration was 78.8 km/h, with a torque of 24.18 Nm at 987 rpm and an output power of 2.8 kW at 1526 rpm.
