Throughput is the ability of a company's production unit to process raw materials into final products that have value, in accordance with established standards. Palm Oil Mill (PKS) is a processing company for raw materials in the harvest of palm oil in the form of Fresh Fruit Bunches processed into Crude Palm Oil (CPO) and Palm Kernel Oil (PKO) products and their by-products in the form of solid waste (empty bunches, fiber, shells) and liquid. PKS production can be achieved throughput produced by looking at the production process that occurs in each work unit, namely: the value of the capacity of the stew is done, sequencing time, steam boiler requirements, Material Balance. The capacity owned by PKS XYZ is 60 tons/hour, does not meet the targeted throughput, where the sterilizer capacity is only able to reach 45 tons/hour, sequencing time is 45 minutes, the steam boiler produced is not sufficient to produce 60 tons of PKS/hour, and the existing Material Balance is not met, which are 38 tons/hour.

Quality is a factor that determines the success of a product penetrate the market, in addition to other major factors such as price and service. Quality products will have great competitiveness and high quality level. Products produced from extracts of natural ingredients, one product is Black Tea extract. To maintain customer satisfaction, the company tries to emphasize the value of DPU that occurs. This study aims to analyze the defect reject from the production of Black Tea Extract for a year using SIPOC diagram (Supplier Input Process Output) and Pareto diagram. Result of research is total production during that period equal to 358 batch x 300 Kg = 107400 kg, total reject of 78 batch x 300 kg = 23400 kg, with total reject for Black tea extract 21,79%. Can be known in the process of Black Tea extract reject largest in reject brix out of spec for 93.67% and Reject Tannin out of spec 6.33%. So it can be concluded that the dominant reject of the production process for black tea extract products is reject brix out of spec.

The gel strength and profile texture was the most important physical characteristic of gelatin. Unfortunately, the gelatin based on alternative source such as bone of fish has low gel strength and profile texture value compared mammalian gelatin. In another side, the extraction gelatin method has been using more saver solvent such as citric acid and water. The aim of this research was extracted gelatin from bone of fish using pineapple waste and water. Then continued with the gel strength and profile texture analysis of gelatin crude extract. The result shown that the fish bone gelatin successful extracted using pineapple waste combined with warm water at pre-treatment and main extraction respectively. The gel strength of fish bone gelatin was 430 g.bloom. Profile texture of crude extract fish bone gelatin including hardness was 9.83 N, cohesiveness of 0.46, springiness of 2.91, gumminess of 4.52 N and chewiness of 14.30. The result suggested that liquid crude extract of fish bone gelatin was comparable toward mammalian and another fish gelatin

Bearing is a mechanical element that resembles a loaded shaft, so that rotation or back and forth motion can be smooth, safe and long lasting. Bearings should be sturdy and durable to allow the shaft and other machine elements to work properly. If the bearing is not working properly then the performance of the whole system will decline or not work properly. For this reason, materials from high-carbon steel bearings should be durable and durable. To obtain the desired properties of the metal, the Heat Treatment process, especially the outer and inner ring, is used. Hardness testing of the outer and inner ring of the bearing is performed after the Heat Treatment process. Testing the violence using the Digital Rockwell Hardness Tester, the value of the violence can be read directly on the scale of the tool. The Heat Treatment process of the outer and inner ring of the bearing can produce the mechanical properties that the manufacturer wants, namely Rockwell hardness 62-64 HRC. If the result of the hardness test is in accordance with the factory standard, then the outer and inner ring meet the manufacturer's quality requirements.

Fatigue Analysis Aluminium 6063-TF on the Rotary Bending Testing Machine Ery Diniardi; Boy Setiawan; Anwar Ilmar Ramadhan

Some of the damage that occurs in the structure and construction of engine elements that experience dynamic loading at the time of operation is caused by fatigue (fatigue), which occurs without beginning signs so that it causes great damage and loss. Fatigue strength is the process of local changes in the structure that occur permanently in accordance with the period of time caused by conditions where stress or strain occurs which results in cracks or fractures after being subjected to repetitive loads. Surface roughness factors that affect fatigue are applied in the analysis and application of machining, which are finely grinded and rough machined. Analysis was carried out on 6063-TF aluminum alloy material which is widely used for motor vehicles. To find out the effect of the above, the fatigue strength test is carried out with a Rotary Bending Fatique Test to obtain a cycle value or fatigue age and certain neighbors so that it can make a semi-log S-N diagram with statistical calculations.

Publisher : Faculty of Engineering Universitas Muhammadiyah Jakarta

Liquid organic fertilizer has been developed to reduce the dependence of cultivated plants on inorganic fertilizers. based Oil palm fruit fiber, as a by-product of processing palm oil mills, potentially used as organic fertilizers. The purpose of this study was to obtain liquid organic fertilizer from fermented oil palm fruit fiber and analyze the effect of the fertilizer on the growth of oil palm seedlings. Two stages of the research were conducted. The first stage was processing the fibre into liquid organic fertilizer by chopping the oil palm fruit fiber and adding local microorganisms as activators. The fermentation process was carried out for 7 days. The second stage was applying fermented organic fertilizer (POC) to the oil palm growing media. The Completely Randomized Design Method was applied with 5 treatments, namely: P0 (subsoil with no fertilizer), P1 (soil + NPK), P2 (soil + 20 ml POC), P3 (subsoil + 40 ml POC), P4 (subsoil + 60 ml POC). The POC was applied once every week for 16 weeks. The results showed that liquid organic fertilizer had a significant effect on the height of palm seedlings at 4 MAP at 20 ml per seed. The oil palm seed growth tend to increase in several parameters observing in plant diameter, plant biomass and leaves greeness. Liquid organic fertilizer obtained from oil palm fruit fiber can be applied as alternative fertilizer in the prenursery. Further research related to the optimization of process producing liquid organic fertilizer and its application to other cultivated plants is highly recommended.

Indonesia must face the risks of volcanic eruptions, earthquakes, floods and tsunamis, destruction of its land areas, and resulting in damage to client and server computer systems. The demand for the information technology availability and performance becomes high. Disaster recovery plan is designed to ensure the vital business processes continuation in the event that a disaster occurs. The problem is how to make the best way in selecting backup recovery strategy based on the benefits to the cost ratio so as to minimize the business losses that will be caused by the failure of an application system. The research aims to make decisions that can help make certain parties take the best decision in choosing the backup recovery strategy selection for a business continuity plan in the University Trilogy. The method used is the multi-criteria decision making and analytical hierarchy process using the expert choice software. From the data processing results can be concluded that the first order is hot standby option 59.4%, followed by cold standby option 23.3%, then the choice of warm standby option 17.4%. The data inconsistency rate is 0.02, smaller than 0.1 as the maximum value of inconsistency ratio.
