Material komposit dengan laminasi serat penguat karbon dan basalt telah diproduksi melalui proses cetakan injeksi. Tujuan penelitian adalah menganalisa laju korosi material komposit oleh air laut. Perendaman komposit hibrida untuk masing-masing variasi dilakukan pada air laut dengan durasi waktu perendaman selama 2 minggu, 4 minggu, dan 6 minggu. Hasil uji menunjukkan seluruh variasi komposit hibrida mengalami penyerapan dibuktikan dengan meningkatnya massa benda uji dari setiap durasi waktu perendaman. Peningkatan massa untuk masing-masing komposit hibrida sangat besar terjadi pada minggu ke-2 (dua) yaitu 3,9% untuk CFRP, 1,4% untuk B2C3B2C3, 1,3% untuk B4C6, 1,3% untuk C2B2C2B2C2, dan 1,5% untuk BFRP. Kemudian untuk durasi perendaman selanjutnya relatif tetap (constant). Dari hasil tersebut disimpulkan bahwa perendaman komposit hibrida dengan serat basalt/carbon/epoxy sangat rendah dari minggu ke minggu. Analisa SEM menunjukkan pada setiap komposit hibrida teramati terjadi korosi disebabkan karena serat basalt memiliki kandungan besi (Fe), tetapi laju korosi sangat rendah (< 0,5%). Efek korosi ditunjukkan dengan adanya zona delaminasi yang dapat menurunkan kekuatan dan keuletan dari komposit hibrida. Composite materials with carbon fiber and basalt fiber laminates have been produced through the injection molding process. The aim is to analyze the corrosion rate of composite materials by sea water. Immersion of hybrid composites for each variation was carried out on sea water with a duration of immersion time of 2 weeks, 4 weeks and 6 weeks. The test results showed that all variations of hybrid composites experienced absorption as evidenced by the increase in the mass of the specimen from each duration of immersion time. The mass increase for each hybrid composite was very large at the second week is 3.9% for CFRP, 1.4% for B2C3B2C3, 1.3% for B4C6, 1.3% for C2B2C2B2C2, and 1,5% for BFRP. Then for the duration of subsequent immersion it is relatively constant. From these results it was concluded that immersion of hybrid composites with basalt / carbon / epoxy fibers was very low from week to week. SEM analysis showed that each hybrid composite observed corrosion due to basalt fibers having iron (Fe) content, but the corrosion rate was very low (<0.5%). Corrosion effects are indicated by a delamination zone which can reduce the strength and ductile of hybrid composites.

This study investigated the rate of flame propagation and residue quality of epoxy composite with jute fiber reinforcement. Three layer of jute fibers were stacked as reinforcement of composites. It was manufactured by the injection method (vacuum assisted injection, VARI). In this study, the zippo oil as flame trigger was added on the specimen. This study aims to investigate the effects of zippo oil on the rate of flame propagation and residue of composites. The flame rate testing was based on ASTM D 635 standard, with repetitions of 5 times for each sample that conducted inside of the combustion chamber. Test results obtained in addition to carbon dioxide (CO2) are carbon monoxide (CO) and methane (CH4), as well as dust particles (PM10). The result of measuring the flame propagation rate with zippo fuel is 0.23 mm/s, while composite without zippo oil is 0.17 mm/s. Furthermore, CO2 residue with zippo oil addition is 1.55% and without zippo oil is 1.57%, respectively. Meanwhile, residual test results for contaminants such as carbon monoxide (CO) and Methane (CH4) from composites with the addition of zippo oil were 0.006 % and 0.008% respectively. In additional, the remaining composite burned without zippo oil has an equal value of CO and methane about 0.002%. The conclusion shows that there was an increase of flame propagation rate and residual value produced after the addition of zippo oil, and that pollutant residues exceeded threshold value.

Phase change material (PCM) is a material that can absorb and store energy and can release it based on the principle of latent heat energy storage. Beef tallow is one of the materials that can be used as PCM but its low thermal conductivity is around 0.181 W/mK. Hence, thermal conductivity is considered an important factor in the conduction heat transfer. This further affects kinetic absorption and heat release. However it is possible to increase the values by adding another material that has a high thermal conductivity. The purpose of this study is to elevate the thermal conductivity of beef tallow by adding rice husk char. This research involves direct incorporation method, where beef tallow is thawed and mixed with the rice husk char then stirred with a rotation of 100 rpm until the mixture becomes solid. Addition of rice husk char with weight fractions of 5 and 10% and grain size of 0.045 mm. Subsequently, thermal conductivity test was performed using the TQ Heat Transfer Experiment Base Unit.The results show that with the addition of rice husk can increase the thermal conductivity of PCM beef tallow. The increase obtained in the addition of 10% rice husk char is 37 times compared to the pure sample. Based on this result it is concluded that carbon-based materials such as rice husk char can be used to increase the thermal conductivity of PCM materials.

Abon is one of the people's favorite menus made from shredded chicken or beef. This reality has led to the development of many shredded products with various raw materials, such as shredded eel, shredded fish, shredded shrimp, shredded catfish, and even shredded eggs. The model for develo ping shredded eggs from egg raw materials was eyed by a women's business group in Baluk village, Negara sub - district, Jembrana district. The business group in question is the Women Farmers Group (KWT) Pitik Jaya, which began in 2014 by experimenting with their unique product, shredded eggs. The business of making shredded eggs is actually quite prospective because the egg raw materials are produced by the KWT itself. However, this group has problems related to productivity and efficiency, namely in the process of draining shredded oil which is still conventionally done by simply placing shredded coconut on aerated niru. Efforts to overcome the existing problems are carried out by replacing conventional equipment with spinner machines. This machine is multi-functional and is built by a dedicated team so that it can also be used for other product oil extraction. The result of the activity was that the team succeeded in designing and manufacturing a multi-function shredded oil spinner machine with a capacity of 420 eggs per day, so that the use of this machine increased the quality of shredded eggs produced by KWT Pitik Jaya and increased productivity by up to 450%. Keywords: spinner machine, egg shredded, multi function, productivity
