Abstract

Pengolahan sampah di Indonesia masih belum optimal ditangani. Sementara itu produksi sampah kota terus menerus meningkat setiap tahunnya termasuk kota cilegon. Fakta ini mengindikasikan desakan untuk membuat terobosan dan pengembangan pengelolaan sampah sehingga tidak terjadi dampak buruk akibat timbunan sampah. Beberapa daerah sudah membuat perencanaan untuk membuat TPA yang mengolah sampah dengan teknologi yang tepat seperti penanaman pipa pada sel TPA sebelum di isi dengan sampah sehingga nantinya akan “panen” biogas dari sampah. Bagendung sebagai TPA cilegon sudah semestinya memiliki instalasi biogas untuk pengolahan sampah.

Abstract

Pemanfaatan TPA telah terbukti efektif untuk menjadi sumber energi terbarukan. Sampah Kota Cilegon dengan karakterisstik lebih besar komposisi sampah organiknya seharusnya dapat dimanfaatkan untuk menghasilkan biogas dalam hal ini metana (CH₄). Produksi metana dari sampah organik terjadi karena aktifitas mikroba tertentu yang menguaraikan sampah organik. Seperti makhluk hidup lainnya, mikroba ini juga keberlangsungan hidupnya sangat tergantung terhadap kondisi alam sekitar untuk mikroba dapat berkembang dan beraktifitas dengan optimum. Metode yang digunakan untuk menangkap biogas dari TPA Begendung dengan pemanfaatan saluran lindi menunjukkan kadar metana yang dihasilkan hanya berkisar 14%-15%. TPA yang dapat dimanfaatkan biogasnya paling tidak mempunyai kadar metana lebih dari 50%, sehingga saluran lindi saja tidak cukup untuk memnafaatkan biogas dari sampah kota. Pengujian yang dilakukan juga menunjukkan bahwa produksi metana dipengaruhi oleh temperatur lingkungan dimana kondisi lingkungan TPA Begandung temperaturnya berkisar 28°C-34°C. Pengamatan dilapangan menunjukkan bahwa produksi biogas stabil pada temperatur 30°C.

Abstract

Sampah merupakan hasil samping kegiatan manusia yang seringkali dikesampingkan karena dianggap tidak berguna dan menjadi sumber pencemaran lingkungan. Sebaliknya dunia saat ini mengalami krisis energi akibat cadangan energi fosil yang semakin menipis. Hal ini menuntut dilakukannya pengembangan teknologi pengolahan sampah sebagai sumber energi seperti teknologi anaerobic biodigester. Paper ini menampilkan hasil eksperimen pengolahan sampah organik dengan anaerobic biodigester dengan starter kotoran sapi, kotoran  kambing dan air lindi. Hasil penelitian menunjukkan biogas yang dihasilkan dari starter kotoran kambing memiliki kadar gas metana sebesar 64,3%. Nilai sangat baik mendekati nilai maksimal standar biogas menurut Energy Resources Development Series No. 19 Esca, Bangkok dengan kisaran kandungan metana sebesar 55-65%

Abstract

Penumpukan sampah dengan metode landfill selain mencegah pencemaran lingkungan juga dapat menghasilkan biogas dengan kandungan metana (CH4) sebagai sumber energi. Penelitian ini ditujukan untuk mengetahui kualitas biogas dengan instalasi yang telah terpasang sebelumnya pada tumpukan sampah dengan metode landfill di Tempat Pembuangan Akhir (TPA) Bagendung. Pengukuran dilakukan pada pusat terminal grid dengan pompa hisap untuk zona 1A – 1C (tahap 1). Hasil pengukuran menunjukkan kualitas biogas yang ditunjukkan dengan kandungan gas metana meningkat sejalan dengan meningkatnya temperatur lingkungan. Kandungan gas metana tertinggi diperoleh saat temperatur lingkungan berkisar pada 35 – 36 ◦C mencapai 13,89 %. Nilai ini masih sangat rendah untuk dapat dipergunakan sebagai bahan bakar. Melihat kondisi dilapangan dugaan terbesar adalah terjadinya kebocoran pada pipa-pipa riser yang terpasang pada instalasi tersebut.

Abstract

One example of the current development of the plastic industry is Anti-Bacterial Plastic. Anti-bacterial plastic is a plastic that can store food well, even for a relatively long time compared to plastic in general. In the industrial world, companies are required to continue trying to find various ways and efforts to be able to compete with other companies that have the same business field. Defective products are products produced from a factory or industry where the product does not meet predetermined product quality standards. According to consumers, a good quality standard is if the product can be used according to consumer needs. However, if the product cannot be used according to consumer needs, then the product can be said to be a defective product. By analyzing defects in the antibacterial plastic manufacturing process, it can be useful to find problems that arise in the plastic packaging manufacturing process. The research method is carried out using a process of experimentation and measurement as well as checking defects visually. From the research results, three types of defects in anti-bacterial plastic products were found, namely eyelets, shrinkage and dimensional defects. These defects are characterized by spots on the plastic surface, wrinkles on the plastic surface, and dimensional differences in the plastic.

Abstract

The development of Renewable Energy (RE) has become one of the priorities that has been promoted by various governments around the world, as a step towards implementing green energy in accordance with the Paris Agreement. The sea as one of the largest parts of the territory in Indonesia must be managed for its energy because it has quite large energy potential. One of them is ocean currents. The Sunda Strait is a very strategic strait and has ocean currents that have the potential to develop energy to be used as a source of electrical energy. Therefore the development of a suitable turbine design is urgently needed in this strait area. In previous research the simulation and experimental work have confirmed that the Savonius rotor can be worked in the low speed marine current. This is will be relevant with Sunda Strait condition that have current 0.4 – 1 m/s. The experiment also shows that the rotor provided torque 0.36 Nm with 11.97 RPM therefore can generated 0.45 Watt

Abstract

Natural fiber-based composite materials are becoming an environmentally friendly alternative that continues to be developed due to their abundant availability, light weight, and low production costs. This study aims to determine the effect of volume fraction and fiber direction on the mechanical properties of empty oil palm fruit bunch (OPEFB) fiber-based composites, particularly impact toughness and flexural strength. The composite manufacturing process was carried out experimentally using hand lay-up and compression molding methods. OPEFB fibers were used as reinforcement and polyester resin as matrix, with the addition of MEKPO catalyst at 1% of the resin volume. Composites were varied based on fiber volume fraction (20%, 30%, and 40%) and fiber direction (0°, 45°, and 90°). Impact toughness testing was carried out using the Izod method referring to ASTM D256, while flexural strength was tested using the three-point bending method (ASTM D790). The results showed that a 30% volume fraction with a 0° fiber direction produced the highest flexural strength of 95.7 MPa, while a 40% volume fraction with a 45° direction showed the highest impact toughness of 28.1 kJ/m². Increasing the fiber volume fraction above 30% decreased the flexural strength due to fiber agglomeration. The 0° fiber direction was optimal for flexure, while 45° was most effective for absorbing impact energy.

Abstract

Mobile Poultry Slaughterhouse Halal (MPSH) is a mobile facility designed to carry out the process of slaughtering chickens in accordance with halal principles in the Islamic religion. Making a prototype of this tool aims to test the functionality of a system or product. The machine development designed in this research uses a drive (transmission) as a combination of pulley and v-belt. The reason for using a drive system as a pulley and v-belt is that it feels easier and more efficient in the work process. This research aims to analyze the calculation of pulley and v-belt sizes suitable for the plucker machine that was developed. This research uses an experimental design method, namely carrying out measurements, observations, and calculations of the technical specifications of the machine, then analyzing the data to obtain an idea of the machine's performance, which ultimately can provide an idea of the suitability of the machine. The research results obtained: (1) pulley sizes 100 mm and 175 mm in diameter, made from ST37 steel. (2) Required v-belt length = 1,253.95 mm. (3) V-belt axis distance = 426.25 mm. (4) The circumferential speed of the driving pulley vP = 10.99 m/s. (5) The circumferential force that arises Frate = 111.37 N. (6) The number of belts used is 1 belt.

Abstract

Clean and healthy air are major topics around the globe. It is because poor air quality hurts human health and is even responsible for the deaths of millions of people. This work develops exhaust pipes containing filters to reduce the pollutants emitted by motorcycles. There are three pollutant concentrations measured here: CO2, CO, and HC. The measurements were taken before and after the filter system so that the pollutant reduction could be calculated.  The maximum pollutant reduction of the filter system: 6.1 % of CO2, 8.0 % of CO, and 651.0 ppm of HC. The primary mechanism of this filter is the physical trapping of pollutants. When the gas flows through the exhaust pipe, the pollutants in the stream are attached to the filter due to direct contact. This change can be visually observed in the filter color, which darkens after use in the exhaust pipe. However, a limitation of this work is its short-term experiment, which lasted only five minutes, indicating a key area for future research. It is also necessary to have alternative filters that are sustainable and can work properly in high-temperature conditions.

Abstract

Agriculture waste-based materials have considerable potential as wood-based particleboard alternatives. It has been produced abundantly from nature and considers an eco-friendly material. One of the enormous resources is the paddy by-product, rice straw (about 500 million tonnes per year worldwide). In this work, the mechanical properties of rice straw-based particleboard are predicted easily and quickly using the sessile drop method.  Rice straw was crushed into 2-5 mm diameter powder-like materials, and corn starch was used as the binder. The rice straw particleboard was formed under a hot press machine (5 MPa, 180°C and 120 minutes). Conventionally, the sample mechanical property was tested through Universal Testing Machine (UTM). Unfortunately, the process is costly and difficult to access. It is necessary to have a rapid and low-cost presumption of the mechanical particleboard properties toward more efficient manufacturing. This work proposes a simple sessile drop method to indicate particleboard mechanical properties. Multiple linear regression was performed to see the correlation between sessile drop and UTM testing. It was found statistically that the sessile drop method could be used as an early prediction of particleboard mechanical properties.
