Abstract

Limited Liability Company (PT) Beurata Subur Persada is a large company engaged in palm oil processing with an area of approximately 23 hectares of activity. In the processing there is a steam catter/boiler working tool. This steam boiler engine is often used as a production engine in industrial companies. Steam boiler or boiler is a container that is very tightly closed in which the heat of combustion flows until hot steam is formed. The analysis uses a data processing application, then the calculation and data retrieval starts from march 11 to August 13 2021. The results of the study state that the components of the steam boiler at a capacity of 20 Tons/hour are the most important, namely the burner, evaporator pipe, combustion chamber, water reservoir. from economizers, superheaters, steam heaters and ash or ash collection devices from combustion. Calculations at a high calorific value (HHV) of 5,691.17 Kcal/Kg and a low calorific value (LHV) of 4,608.96 Kcal/Kg used shell and fiber fuel with a ratio of 3:1 with a percentage of 25% shell and 75% fiber. Keywords: Steam Boiler,Heat Value, PT.

Abstract

Korosi merupakanpenyebab utama kegagalan dini banyak infrastuktur yang berada di daerah pesisir. akibat bencana gempa dan tsunami Desember 2004 Perubahan iklim disepanjang garis pantai Barat Selatan Aceh semakin tinggi, kerusakan tersebut berdampak pada lingkungan sekitarnya, angin menjadi lebih kencang dan kandungan garam klorida dalam udara menjadi meningkat hal ini memacu peningkatan laju korosi atmosferik pada konstruksi-konstruksi yang terbuat dari logam, Penelitian ini bertujuan untuk mengkaji dampak perubahan laju korosi atmosferik yang terjadi pada kawasan tsunami yang berjarak dibawah 5 km dari pinggir pantai terhadap kawasan yang tidak dilanda tsunami yang berjarak diatas 5 km dari pinggir pantai, untuk logam kontruksi yang sering digunakan oleh masyarakat untuk infrastruktur. Enam lokasi penelitian pengukuran laju korosi atmosferik dipilih, yaitu: Pasi Ujong Kalak, Peunaga Pasi, Kubang Gajah penelitian tahun 2014 kawasan pesisir dan Alue Peuyareng, Pasi Jambu, Paya Lumpat penelitian tahun 2015kawasan rural berdasarkanASTM G 50. Hasil penelitian lajukorosi atmosferik menunjukkan bahwa semakinjauh dengan pinggir pantai maka laju korosi atmosferik akan menurun rata-rata untuk baja tulangan 1,62 mpy, baja nako1,06 mpy, baja strip 2,95 mpy, baja siku 0,25 mpy, baja plat mencapai 0,67 mpy.

Abstract

 Environmental pollution that can cause atmospheric corrosion is the exhaust gas (exhaust fumes) generated from operating the palm oil industry. This atmospheric corrosion will reduce the volume and material mass of a machine component, so that if it reaches certain conditions the strength of the material will result in failure of industrial machine components. The corrosion rate of the construction steel can be measured using the weight loss method according to the ASTM G-50 standard and the ASTM G-1 standard. The research was conducted for one year and data collection was taken every month, the research location was at PT Agro Sinergi Nusantara Batee Puteh. The results of the study, the highest corrosion rate occurred in strip steel reaching 0.57 mpy in October and the lowest corrosion rate occurred for angled steel in September and cylindrical steel in May with a corrosion rate of 0.06 mpy. Keywords— atmospheric corrosion, palm oil industry, ASTM G-50, ASTM G-1, corrosion rate

Abstract

Penggunaan tepung bonggol pisang sebagai bahan baku pembuatan plastik biodegradable merupakan salah satu alternatif penggunaan plastik pati pisang dalam upaya mengurangisampah plastik. Pisang mengandung 66% karbohidrat, protein, air dan mineral penting. Untuk mendapatkan plastik biodegradable, ditambahkan pati bersama dengan CMC (carboxy methylcellulose), gliserol dan minyak sereh sebagai anti bakteri dan antioksidan. Pada penelitian ini dilakukan pembuatan plastik biodegradable campuran pati, CMC, gliserol sebagai plasticizer dan minyak sereh dengan memodifikasi CMC, gliserol dan minyak sereh. Penelitian ini mencakup dua variabel, yaitu variabel tetap dan variabel. Variabel tetap meliputi konsentrasi pati dengan udara 1:5, kecepatan pengadukan 100 rpm dan suhu gelatinisasi pati 70oC, sedangkan variabel yang meliputi konsentrasi CMC meliputi kadar (5,5; 6 ,5; dan 7,5 ) % (b/b), sereh wangi konsentrasi minyak termasuk (15; 20; dan 25) % (b/v), dan konsentrasi gliserol termasuk (25; 35; dan 45)% (b/v). Penelitian ini bertujuan untuk mengetahui pengaruh penambahan CMC (carboxy methyl cellulose), minyak sereh dan gliserol sebagai plasticizer terhadap sifat mekanik, morfologi,dan uji biodegradabilitas , serta aktivitas antioksidan plastik yang dihasilkan. Hasil penelitian ini menunjukkan bahwa plastik biodegradable memiliki nilai kuat tarik sebesar 0,210,38 kgf/mm2; nilai elongasi antara 16 , 3 - 54,20%; Pemeriksaan morfologi menunjukkan bahwa permukaan plastik halus dan plastik terurai sempurna dalam tanah dalam waktu 27 hari. Kata kunci - biodegradable plasti k , CMC , Minyak Sereh, Pati Pisang.

Abstract

The process of making palm oil fresh fruit bunches (FFB) into crude palm oil (CPO) goes through many processing sessions. The processing steps were tried at several stations, including reception stations, sorting stations, sterilizer stations, thresher stations, digester and press stations, and clarification stations. One very useful process lies in the sterilizer station. The quality of the resulting CPO, one of which depends on the boiling process at the sterilizer station. FFB boiling process at PT. Socfindo seunagan uses a triple peak system, with pressures near 2.5 to 3 bar. The boiling process is tried for 80 to 85 minutes. The processing time, which takes so long, will ripen the fruit to the bottom

Abstract

The west coast of Aceh region is an area that is passed directly to the Indian Ocean, the Malacca Strait and the Gulf of Bengal. The tsunami that Aceh in December 2004 has led to the greater part of the coastal region of Aceh, including the region of Aceh Barat and Nagan Raya merged in seawater and the impact on the destruction of the environment around the coast. This condition causes the infrastructure in tsunami affected area becomes more susceptible to corrosion attack. This condition is exacerbated by the fact that the Aceh region is an area that is prone to earthquakes that have corroded infrastructure can suddenly collapsed during the earthquake occurred at a smaller scale. This study aims to look at the effect on the rate of corrosion of structural steel in the region of Aceh Barat and Nagan Raya. This research is done on location Peunaga Pasi For West Aceh region and village Kubang Gajah To Nagan Raya area. Testing methods to lose weight with the exposure time period of five months. The results showed that the corrosion rate of the highest value for western Aceh region ranged from 0.74 to 4.29 mpy and to Nagan Raya ranged from 0.85 to 2.61 mpy. For all types of steel in this region the level of corrosion rate is still relatively low. Keyword : Atmospheric Corrosion, Steel Construction, Corrosion rate.

Abstract

PT. Wiratako Mitra Mulia is a company engaged in asphalt construction and road repair. At this time PT. Wiratako Mitra Mulia uses several heavy equipment to facilitate the work process, one of the heavy equipment used by PT. Wiratako Mitra Mulia is an excavator which is used for the process of dredging soil, moving materials and leveling the ground. From this, there are several obstacles or problems that occur in the excavator, such as damage to the bucket hydraulic cylinder, in which the bucket hydraulic cylinder has an oil leak, cylinder piston damage and seal leakage, therefore proper and scheduled maintenance is needed so that the damage that occurs to the hydraulic cylinder of the bucket excavator can be minimized so that the work process can run smoothly and do not experience any problems. Therefore, daily, weekly, monthly and yearly maintenance is required. For daily maintenance carried out every day by checking lubricants and performing services, for weekly maintenance inspections are carried out every 60 working hours. For monthly maintenance it is done every 250 working hours and for annual maintenance it is done every 2500 working hours.
