Abstract

AbstractGood harvesting technique and timing is necessary to result good productivity in oil-palm industies. The harvesting activity is mostly conducted by ‘human powered’ manual handling which quite arduous and risky in term of work safety and musculoskeletal disorders (MSD). This research deals with anthropometry and motion study to analyse manual harvesting activity in oil palm plantation so the activity can be done in more safety, efficient and productive. Motion study using Natural Range of Motion (ROM) is applied to know the level of motion risk based on ROM indeks and appropriate antropometry. Manual harvesting tasks by usingconventional tools named ‘dodos’ and ‘egrek’ were studied in this research. The aims of this research is to know the pattern and risks distribution of the work motions, and then to determine a good harvestingprocedure to minimize the risk. The anthropometry result show that the harvester posture is ideal and uniform. The ‘cutting with egrek (CuE)’ was found as the most risky work element in the manual harvestingtask, and the MSD risks occur on the neck, shoulder, forearm, back and ankle.Such work procedures should be designed and appropriate working distance and length of tool are required to prevent the risks. Work motion simulation revealed that 1.5, 2.5, 5.5, and 8.5 mare suitable working distance to harvest 3, 6, 12 dan 18 mheight of targeted bunches, respectively.Keywords: ergonomic, manual harvesting, oil palm, motion study, anthropometryAbstrakTeknik dan waktu pemanenan yang tepat diperlukan untuk mencapai produktivitas yang baik di industri kelapa sawit. Kegiatan panen sawit secara umum masih dilakukan secara manual mengandalkan tenagamanusia yang tergolong cukup sulit dan beresiko tinggi dalam hal keselamatan kerja dan gangguan muskuloskeletal (MSD). Tujuan dari kajian ini adalah untuk menganalisis kegiatan panen-muat kelapa sawit di beberapa perkebunan sawit dengan pendekatan ergonomi dan mekanisme kerja yang optimal, baik dari sudut pandang efektivitas maupun keselamatan kerja. Lingkup yang dikaji dalam kajian ini adalahberfokus pada analisis antropometri serta gerak kerja pemanenan dengan pendekatan selang gerak alami (natural Range of Motion: ROM). Kajian ini juga meliputi dua metode dan alat panen yang lazim digunakan, yaitu ‘dodos’ dan ‘egrek’. Hasil analisis antropometri secara umum menunjukkan bahwa pemanen di ketiga lokasi memiliki karakteristik postur tubuh yang relatif sama. Analisis gerak membuktikan bahwa elemen kerja yang terkait pemotongan tandan buah segar (TBS) memiliki resiko yang lebih tinggi dibandingkan dengan elemen kerja yang terkait dengan evakuasi dan pengumpulan TBS. Elemen kerja ‘cutting egrek(CuE)’ teridentifikasi sebagai pekerjaan paling beresiko, dimana segmen tubuh yang paling beresiko adalah leher, bahu, punggung-pinggang, lengan hingga pergelangan kaki. Desain ergonomis terkait prosedur danjarak kerja diperlukan untuk meminimasi resiko tersebut, dan hasil simulasi menunjukkan bahwa jarak kerja yang ideal dan aman untuk ketinggian target potong (TBS) 3, 6, 12 dan 18 m berturut-turut adalah 1,5, 2,5, 5,5 dan 8,5 m.Kata Kunci : ergonomika, pemanenan manual, kelapa sawit, studi gerak, antropometriDiterima: 02 Desember 2014 ; Disetujui: 24 Februari 2015

Abstract

An Office Boy (OB) has a big role in helping employees in a company. PT XYZ is one of modern office building located in Jakarta’s prime business district along Jalan Thamrin, Jakarta. PT XYZ has office boys, the office boy’s job includes cleaning and tidying the room and office equipment, serving requests of employees and company guests. The job of distributing gallons of water carried out by the office boy from the pantry to the 13 divisions is a tough job. It is important to know the risk and the force that occurs on the spine as well as an ergonomic risk analysis. The force received by the spine (L5/S1) is 2253.34 N, where the force is still within normal limits, but based on the REBA method the activity of lifting gallons of water poses a very high ergonomic risk. This risk can cause injury, especially if it is done for a long period of time. It is necessary to improve work posture such as lifting a lower body posture/squatting or with another device.

Abstract

Pengendalian hama dan penyakit pertanian sering dilakukan secara kimia dengan menggunakan sprayer, salah satunya adalah sprayer semi-otomatis (knapsack sprayer). Sumber tenaga dan kendali pada knapsack sprayer berasal dari tenaga manusia. Operator harus memompa cairan yang terdapat pada tangki dan menyemprotkannya ke tanaman. Hal ini sering kali menyebabkan kelelahan otot di antara para pekerja. Oleh karena itu, dibutuhkan analisis terkait beban kerja petani saat pengaplikasian knapsack sprayer. Analisis beban kerja dilakukan dengan merekam denyut jantung petani laki-laki dan perempuan. Alat yang digunakan dalam pengukuran adalah Heart Rate Monitor (HRM). Pengukuran dilakukan dua kali, yaitu pengukuran saat kalibrasi dengan menggunakan metode step test dan pengukuran di lapang saat aktivitas penyemprotan. Tujuan dari penelitian ini adalah untuk menentukan beban kerja kualitatif (tingkat kejerihan) dan kuantitatif (konsumsi energi kerja). Hasil penelitian menunjukkan bahwa perempuan memiliki tingkat kejerihan yang lebih tinggi dibandingkan laki-laki, sedangkan konsumsi energi kerjanya tidak jauh berbeda. Dari hasil tersebut, dapat disimpulkan bahwa pengaplikasian knapsack sprayer di kecamatan Wedung lebih cocok dilakukan oleh laki-laki.

Abstract

SBR Snacks, engaged in food, produces various kinds of snacks such as bread, banana chips and opak gambier. The problem in this industry is that when ordering the same product, if the manufacturing process is different for each order, there will be delays in the manufacturing process. In this study, a time study was conducted by observing three products commonly produced by the domestic industry from these snacks. Based on the time survey conducted, it was found that there is no set time standard for the manufacturing process of each product. Adjustment and tolerance procedures are used when setting the standard time. From the results of the study, the standard time for each product was 1670.34 seconds for bread products, 2205.84 seconds for banana chips, 2268.84 seconds for opaque gambier.

Abstract

Transportation has an important role in the logistics of a company, both in services and products. Increased orders in 2020 for wooden speaker products at CV. XYZ (Wonoayu-Sidoarjo) makes this company try to minimize transportation costs at their operational level. This study focuses on determining the relationship between changes in the type of fleet vehicle and the depot location on the operational costs of product delivery and the time to return to the depot in terms of adding trips. The methodology used in this study is the CVRP Multi Trip with Heterogeneous fleet vehicle and the Gravity Location Model based on the heuristic method. Saving heuristic method and nearest neighbor are heuristic methods used in computational studies to determine the order of visits to the formed sub-routes. There are 4 scenarios that are modeled to further analyze the results of these computations, namely: (1) CVRP multi-trip of old location with wings box truck, (2) CVRP multi-trip of old location with Fuso truck, (3) CVRP multi-trip of the new location with wings box truck, and (4) CVRP multi-trip of the new location with fuso truck. The results of the study concluded that there is a relationship between: (1) changes in fleet vehicle type with total traveling distance, (2) changes in depot location with total traveling distance, (3) fuel consumption rate on vehicle operating costs, (4) average vehicle speed on the time back to the depot. Scenario 4 is the best scenario in terms of traveling distance, fuel costs and delivery time. However, moving the depot center is not easy, so the scenario 2 is the most applicable condition considering that the fuso truck is available and has a higher utility than the wings box truck

Abstract

Small companies that do not pay attention to product quality will experience marketing problems such as decreased product sales. Therefore, quality control is required for each product. Banana chips, for example, are considered very difficult to manufacture and often experience product defects. The cause of product failure is a weakness of a business today. The cause of this failure is unknown until now. Banana stick production based on data from August to September 2020 shows the number of defective products is approximately 28,875 kg of the total production, which is 323 kg. Therefore this research is intended to determine the factors that affect production defects in banana sticks. While the benefit of this research is to be able to control the factors that affect defects in banana sticks and can later increase profits and work productivity. The Six Sigma method is one of the tools commonly used in product quality control, where the concept of this method is to set quality standards of up to 3.4 rejects per million possibilities. Based on the results of banana chip defect data, it was found that the type of defect was sluggish with a percentage of 61% and the type of defect was burnt with a percentage of 39%. Factors that affect the two defects include human factors, materials, machines. The suggestion from this research is that of the three most influencing factors are humans, materials and machines. Companies need to plan improvements in stages so that in the future these products can achieve lean production.
