Abstract

Manufacturers are pushed to use superalloys such as titanium alloys in the aerospace part due to environmental and economic issues. The refractory properties of titanium alloys result in rapid and premature wear of the cutting tools, especially by thermal diffusion. Therefore, the purpose of this paper is to focus on understanding the characterization of TiAl6V4 in thermo-physic properties. X-ray diffraction (XRD), scanning electron microscope (SEM), electrical resistivity against temperature test, and differential scanning calorimetry (DSC) were conducted to analyze the relationship of phase transformation to thermal properties. Phase analysis showed that TiAl6V4 is composed of two-phase a and b creating a duplex microstructure in which the surface fraction contains about 92,5 % and 7,5 %, respectively. Electrical resistivity against temperature test demonstrated the phase transformation of a to b occurred at 1017°C. This study revealed that the phenomena of phase transformation affected the thermal properties, i.e., thermal capacity, thermal diffusivity, and coefficient of thermal expansion.

Abstract

The amount of rubber seed waste in Indonesia is highly yielded as a side product from a large amount of rubber trees plantation. The rubber seed was not processed become the usefull application yet,  thus it becomes a high volume of waste in each year. An initiative should be done to turn it as a practical material. The rubber seed is potential for natural composite along with the increasing attention toward natural composite application.This work aims to produce natural fibre composite based on rubber seed and characterize it's mechanical properties. In this work, the rubber seed natural composite produced by using the hand lay-up method. Polyester resin YUCALAC BQTN-157 was used as the matrix with the addition of 1% MEKP (Methyl-Ethyl-Ketone- Peroxide) as the catalyst. Mechanical properties of the composite were examined by using a tensile and bending test. Additionally, the water absorption test was performed according to the ASTM D 570. The result showed that the tensile and bending strength decrease with increasing the filler composition, which is added in the composite. The composite, which has the filler composition of 40% was generate the highest tensile strength. In contrast, the lowest tensile strength appeared at the composite with a filler of 60%. The bending strength trend also behaves similarly with the tensile strength as the filler composition increased. Water absorption ability of composites displays the acceptable value as it shows within the range of 2.22-2.96%.

Abstract

Substrat Cu dan solder SAC305 merupakan beberapa bahan semikonduktor. Sambungan solder harus memiliki kekuatan ikatan metalurgi yang baik ketika solder dan substrat disatukan. Manfaat solder nantinya akan membuat interkoneksi antara hubungan listrik dalam satu substrat yang akan membentuk senyawa atau lapisan IMC. Dimana terbentuknya senyawa intermetalik (IMC) pada hasil reaksi akan menjadi peran yang penting dari terbentuknya ikatan yang baik antara solder dan substrat. Oleh karena itu dilakukan penilitian ini guna menganalisis interfacial reaction yang terjadi antara substrat Cu dan solder SAC305 ketika disatukan. Pada tahap preparasi spesimen substrat Cu akan dipotong sesuai dengan dimensi yang telah ditentukan dan dilakukan proses cleaning pada bola solder SAC305. Setelah proses preparasi sampel dilakukan proses Interfacial Reaction Couple, substrat Cu dan bola solder SAC305 ditimbang dengan rasio 1:3 dan spesimen substrat dicelupkan kedala fluks pada kedua sisi spesimen. Setelah itu, spesimen substrat Cu dan bola solder SAC305 disusun secara teratur dan diletakkan kedalam tabung kuarsa dan dilakukan proses pemanasan didalam tungku dengan temperatur reflow 270oC, 290oC, 310oC, dan 330oC dengan waktu reaksi 50 menit. Hasil reaksi yang terbentuk antara substrat Cu dan bola solder SAC305 kemudian diamplas dan dilakukan proses karakterisasi dengan mikroskop optik untuk melihat struktur mikro yang terbentuk serta dilakukan karakterisasi material berupa SEM, EDS dan XRD. Hasil pengujian menunjukkan bahwa nilai ketebalan IMC akan meningkat seiring dengan pertambahan variasi temperatur. Serta ditemukannya fasa Cu6Sn5 yang membentuk lapisan kerang serta Cu3Sn yang terbentuk secara planar berdekatan dengan substrat Cu pada lapisan IMC.

Abstract

Pemukiman merupakan salah satu penghasil sampah domestik organik terbanyak, seperti sisa makanan dan sisa taman atau daun dan rumput. Sedangkan sampah domestik anorganik, seperti plastik, kertas, kaca, dan logam tidak banyak. Salah satu alternatif pengolahan sampah domestik organik adalah pengomposan, baik padat maupun cair. RT 37 Kelurahan Telaga Sari, Kecamatan Balikpapan Kota adalah salah satu wilayah pemukiman di Kota Balikpapan yang cukup padat penduduknya. Gagasan untuk melakukan pemanfaatan sampah domestik organik menjadi kompos cair didasarkan dari pengamatan lapangan yang melihat ketertarikan warga merawat tanaman. Oleh karena itu diharapkan dengan adanya kegiatan pembuatan kompos cair dari sampah domestik organik dapat mengurangi jumlah sampah yang dibuang ke TPS/TPA dan menjadi salah satu sumber nutrisi bagi tanaman milik warga. Dalam pelaksanaannya masyarakat sangat antusias, yang dibuktikan dengan banyaknya warga yang berpartisipasi dalam proses pembuatan kompos cair sampai dengan penerapannya pada tanaman. Hasil dari kegiatan ini adalah adanya kompos cair buatan warga RT 37 Kelurahan Telaga Sari yang digunakan untuk perawatan tanaman di rumah masing-masing. Pada akhir kegiatan, warga setempat menyarankan agar ke depannya kegiatan ini dapat dikembangkan menjadi lebih produktif, salah satunya dengan adanya komersialisasi produk kompos cair.

Abstract

This study was conducted to assess the performance of a printing machine using Overall Equipment Effectiveness (OEE) calculations. The printing machine already meets the World Class standards with availability, performance, and quality metrics set at 85%. Achieving this standard is considered indicative of good machine performance according to these benchmarks. Recommendations for improvement include implementing machine maintenance management supported by routine maintenance by machine operators to minimize issues during production. The results from the OEE calculations show that the availability, performance, quality, and overall effectiveness of the machine have not reached or exceeded the World Class OEE standards. This has caused production delays due to the machine's low performance. The low performance is attributed to the fact that the printing machine operators at CV Delimas do not fully understand the machine's maintenance procedures. The performance metric for the printing machine at CV Delimas using OEE averages only 33%. This indicates that the machine's performance is significantly below the 95% standard.

Abstract

Noncommunicable diseases (NCDs) are common in Indonesia; this is also true in Karang Jati, Balikpapan, and East Borneo. Despite this, the villagers have little knowledge about prevention, despite being aware of the grave consequences that diseases can have on their well-being and social standing. This exercise aims to raise villagers' understanding of the need to prevent non-communicable diseases. Using NCD screening with information distribution, this activity has encouraged the villagers to become more aware of the condition and motivated them to take preventative action. Most of the villagers are at high risk of noncommunicable diseases (NCDs), specifically hypertension, according to the screening results. These data have effectively supported the villagers in establishing NCD screening and management in their neighborhood through Pos Pembinaan Terpadu (Posbindu) PTM, a community-based NCD prevention and management activity.
