Abstract

The availability of oil palm empty fruit bunches in Indonesia could be an important source of biomass to be utilized as a solid fuel feedstock. In this work, the thermal behavior and degradation of oil palm emty fruit bunches was investigated with a thermogravimetric analyzer in nitrogen atmosphere. The samples were heated from room temperature to 900 oC at heating rates of 20 oC min-1. The ultimate and proximate analysis revealed that oil palm empty fruit bunches contains high volatile matter, fixed carbon and ash content while the caliric value was 17.87 MJ/kg. Thermogravic analysis results indicated thermal degradation of samples occurs in three stages, namely drying and evaporation, active degradation and passive degradation. In addition, active degradation commenced at 148 oC with a peak of degradation temperature of 322.5 oC resulting in 68.32% weight loss.

Abstract

A good coal mining process is assessed by productivity and efficiency. Productivity can also be increased by using heavy equipment accompanied by competent operators. As one of the largest coal mining companies in Indonesia, PT Bukit Asam, Tbk is required to always be at the best performance, including at the heavy equipment operator level. This research aims to determine the factors of heavy equipment use as assessed by cycle time on coal productivity. Productivity is limited to the overburden loading process by the Komatsu PC3000SE excavator at PIT 2 Swakelola Tambang Banko Barat. The greatest productivity obtained was 1099 m3 per hour and the average percent productivity was 79.4%. In this research, a match factor of 0.8 was also obtained as a basis for further research that needs to be carried out to optimize the overburden loading and dumping process for PT Bukit Asam

Abstract

Kegagalan pengereman atau rem blong merupakan penyebab umum kecelakaan yang sering terjadi. Muatan berlebih (overloading) dan temperatur tromol yang tinggi (overheating) sering dicurigai sebagai pemicu utama kegagalan pengereman. Penelitian ini memfokuskan pada pengaruh muatan sumbu roda dan temperatur tromol terhadap efisiensi sistem pengereman pada mobil Toyota Avanza. Metode yang digunakan adalah eksperimen dengan variasi tromol standar dan tromol yang telah dimodifikasi. Hasil penelitian menunjukkan bahwa dalam pengujian pengereman, temperatur pada tromol yang telah dimodifikasi menggunakan pendingin air lebih rendah dibandingkan dengan tromol konvensional, dengan perbedaan mencapai 30%. Perbedaan temperatur semakin signifikan ketika temperatur kerja rem mencapai di atas 100°C. Tromol water cooler brake bekerja dengan efektif untuk menahan peningkatan temperatur rem dengan cara menyebarkan panas dari kampas rem ke sirip-sirip tromol melalui perantara air pendingin. Penggunaan cairan pendingin berupa air biasa atau radiator kurang efektif karena rentan mengalami penurunan cepat akibat penguapan. Penelitian ini memberikan wawasan tentang peningkatan efisiensi pengereman melalui modifikasi tromol dengan pendingin air, yang dapat menjadi solusi untuk mengurangi risiko kegagalan pengereman akibat muatan berlebih dan temperatur tromol yang tinggi.

Abstract

Review draft briquettes in context philosophy knowledge this knowledge explains How to approach knowledge and can help us understand the production process, use, and impact environment briquettes. in perspective philosophy knowledge, production briquettes involve the use method scientific, like chemistry and engineering machines, to change biomass to become material burn solid. It involved understanding deep about traits chemistry and physics material standards, as well as the conversion process of energy. Impact environment from the use of briquettes. Using briquettes can influence the ecosystem and impact on the environment. Approach philosophy knowledge helps We dig questions about ethics use briquettes and effort to reduce the negative impact. The Aspect of social economy- related to the production and use of briquettes, like impact on the community local, and how knowledge can help understand the implications of this. This study gives an understanding deep about how briquettes can see through the lens of philosophical knowledge. This thing gives contribution is important in integrating knowledge, ethics, and impact socio-economic in understanding We technology energy alternatives like briquettes.

Abstract

Service is the main indicator of the sustainability of a service. The quality of services is the main factor that must be considered in maintaining the existence and competition of services, including health facility services. This research was conducted at one of the health service providers in the city of Batam. One aspect of health service quality is queuing service. Therefore, the quality of service in the queuing system in health facilities is an interesting thing to research. This research measures the level of optimality of the queuing system currently in effect at the Saffira Mitra Medika clinic. The measurement focuses on service time, the number of patients served, and the waiting time for patients to be served in the queue system. The results of measuring the current queuing system are compared with other proposed queuing system scenarios, so that the level of patient satisfaction as customers is met. The proposed queuing system was obtained through a simulation approach, with the help of Flexsim software. A simulation approach was chosen to facilitate modeling in the proposed queuing system

Abstract

Counter conveyor merupakan alat yang digunakan untuk menghitung suatu objek seperti hasil produksi keripik talas. Pada poses produksi keripik talas permasalahan yang sering terjadi adalah lupa ketika menghitung jumlah hasil produksi. Ketika hasil produksi dilakukan penghitungan biasanya sering terjadi kesalahan penghitungan sehingga menyababkan penghitungan jadi berulang kali.Hal ini menyebabkan hasil produksi lambat disalurkan ke konsumen. Dari permasalahan tersebut, maka dibuatlah solusi dengan membuat alat penghitung otomatis yang dilengkapi dengan conveyor dengan teknik counter menggunakan sensor ultrasonic HC-SR04 sebagai pendeteksi objek yang melewati sensor, NodeMCU ESP826 berfungsi sebagai otak dari proses utama system, dan LCD 16x2 sebagai media tampilan hasil perhitungan produksi keripik talas dan juga dilengkapi dengan sistem IOT (Internet Of Thing) yang mana untuk mentranfer data hitungan ke smartphone atau komputer melalui jaringan. Dengan diterapkannya rancang bangun counter conveyor ini, maka dapat disimpulkan bahwasanya dapat mempermudah perhitungan secara real dan realtime.

Abstract

The appearance of attractive packaging in a product is something that is a major factor apart from product quality. UMKM Keripik Singkong Usaho still have problems with product packaging which is still simple using ordinary plastic without any labeling. So that research and packaging design are needed using the Quality Function Deployment (QFD) method. The results of the study obtained 18 items that become consumer criteria for the packaging of chips products. The results of the House of Quality show that the greatest desire value of consumers (0.07) for the design of chip packaging is an attractive packaging shape (A1), displaying the expiration date (A7), listing the composition (A10), including the halal logo (A11), packaging materials resistant to oil and water (A12), and the position of the product logo is easy to read (A17). So that the technical criteria are variations in packaging color, variations in writing color, variants of packaging materials, and variants of packaging shapes. The proposed packaging design for the chips has two models, red packaging color for the spicy flavor and green packaging color for the original flavor, where each package includes the expiration date, product composition, and halal logo.
