Abstract

Based on Trans Semarang Bus Rapid Transit (BRT) traffic accident data, it is known that the Trans Semarang BRT still often experiences traffic accidents. Corridor I Trans Semarang with the Mangkang-Penggaron route service area is the Corridor with the highest accident rate compared to other corridors. The high number of accidents occurs because of human error. To solve these problems, in this study using the HEART and SHERPA methods. The HEART method is used to find out what activities constitute critical activities that have the potential to cause accidents and also the probability of human error for each critical activity. Then the SHERPA method is used to strengthen the answers of the HEART method and also to determine recommendations for improvement to fix the existing problem. After conducting research and data processing using the HEART and SHERPA methods, it is known that sub-task 6.4 be careful when driving is a sub-task with the highest probability of human error is 0.549. Furthermore, the subtask was given recommendations for improvement in the form of zero accident socialization to all BRT Corridor I Trans Semarang drivers and to make a particular lane for BRT, especially Corridor I so that the road is separated from other private or public vehicles.

Abstract

AbstractHoney extractor is a tool used by farmers group “Bunga Alam Lestari”, Batang Regency to squeeze honey from the honeycomb which has been harvested. The tool owned by the farmers is categorized simple. It is operated manually, therefore the extortion process of honeycomb takes a long time. The tool design is not ergonomic yet since the farmers have to pour the honey manually into the collecting bucket. The farmers also have to move the honey extractor from one farm to another farm during the production period. Researchers improved the existing tools referring to ergonomics concept which is collaborating between manual frame and electric motor (hybrid), increasing the number of frames from 2 to 10, creating mechanism of frame rotating termination (braking), adding of transferal tools,and improving the mechanism of the flow of honey without reversing the tool to pour the honey. The test results of the new tool show improvement of the tools performance, specifically it takes only 180 second for one extortion which producing 16.75 kg of honey. The equipment owned by the farmers needs 360 seconds for one extortion time resulting of 3.35 kg honey.Abstrak Ekstraktor madu merupakan alat yang digunakan untuk memeras sarang madu yang telah dihasilkan oleh lebah yang memiliki nilai ekonomis tinggi. Pengembangan desain dan pembuatan ekstraktor madu ini merupakan perbaikan dari alat yang dimiliki oleh Kelompok Petani Bunga Alam Lestari Kabupaten Batang. Alat yang dimiliki petani memiliki kekurangan antara lain : masih manual, tidak ergonomis, waktu pemerasan sarang madu lama dengan hasil madu yang sedikit, susah dalam pemindahan alat tersebut. Peneliti melakukan perbaikan alat yang ada dengan merujuk pada konsep ergonomi, mengkolaborasikan pemutar frame antara manual dan motor listrik (hybrid), menambah jumlah frame dari 2 menjadi 10, membuat mekanisme penghentian putaran frame (pengereman), penambahan pemindah alat, memperbaiki mekanisme aliran madu hasil pemerasan. Hasil pengujian terhadap alat yang peneliti buat satu kali proses pemerasan dibutuhkan waktu 180 detik dengan menghasilkan 16.75 kg madu sedangkan alat yang dimiliki petani waktu pemerasan 360 detik dengan madu yang dihasilkan 3.35 kg. Jadi dapat dikatakan waktu yang dibutuhkan untuk satu kali pemerasan 50% lebih cepat dengan volume berat madu 5 kali lebih besar dibandingkan dengan alat yang dimiliki petani.

Abstract

PT. Bawen Mediatama merupakan salah satu perusahaan manufaktur dibidang percetakan dibawah Kompas Gramedia Group yang berlokasi di Bawen, Jawa Tengah. Dengan bertambahnya order cetakan dalam proses produksi berlanjut, para operator mengalami kelelahan sebelum melakukan pekerjaan utamanya untuk memproduksi koran kompas beserta cetakan lainnya. Sebelum melakukan pekerjaan utama, operator perlu mengerjakan perkerjaan post press dahulu yang berkaitan dengan menghitung produk, mengontrol hasil, dan jumlah target hasil yang didapatkan. Dengan banyaknya pekerjaan yang dialami para operator dan jumlah operator yang sedikit menyebabkan target menjadi tidak tercapai. Meskipun pekerjaan secara fisik tidak begitu berat karena mesin bersifat semi-otomatis, namun karena pekerjaan yang dilakukan sangat banyak dan target yang seringkali tidak tercapai, hal tersebut membuat para operator mengalami beban kerja mental. Untuk mengatasi hal tersebut, diperlukan penelitian terkait analisis beban kerja. Penelitian ini menggunakan metode NASA-Tlx serta RSME dengan menyebarkan kuesioner yang berisikan indikator beban kerja mental kepada para operator. Hasil penelitian menunjukkan indikator beban kerja mental metode NASA-TLX yang dominan yaitu kebutuhan mental sebesar 21%, lalu diikuti oleh usaha fisik dan mental sebesar 17%, kebutuhan fisik, kebutuhan waktu, performansi sebesar 16% dan tingkat stress sebesar 15%. Sedangkan variabel usaha beban kerja mental pada metode RSME yang besar dilakukan operator mesin cetak web yaitu beban kerja, performansi kerja, dan usaha mental kerja sebesar 18%, diikuti kelelahan kerja sebesar 17%, kesulitan kerja sebesar 15% dan kelelahan kerja sebesar 13%. Usulan perbaikan yang diberikan yaitu sistem peningkatan semangat kerja pada para operator, pembagian operator jika ada pekerjaan post press, melakukan upaya penambahan karyawan pada operator mesin cetak web agar mampu mengurangi beban kerja mental pada operator mesin cetak web, pemberian alat bantu kerja untuk mempermudahkan operator dalam bekerja, serta menciptakan suasana kerja yang nyaman yang diharapkan operator tidak merasa bosan, menaikkan performansi kerja dan menumbuhkan rasa solidaritas antara operator. Kata Kunci : Beban  Kerja Mental, NASA-TLX, RSME, Indikator, Operator Mesin Cetak Web

Abstract

PT NCS LOGISTIC LINK is a Transportation Management Service company or commonly called Freight Forwarding.  PT.  NCS is also engaged in the rental of Warehouses. In the Warehouse at PT NCS LOGISTIC LINK, there is a problem with the layout of the storage of goods in the Warehouse which is still not optimal because the cost of Material Handling in the company is still high and also PT NCS LOGISTIC LINK, a company that manages warehouse rental for companies  manufacture.  The problems faced by PT NCS LOGISTIC LINK today are the problems that are often faced is the handling of incoming and outgoing goods in the company's warehouse, the company still does not have a defined system, so that the placement of goods in the warehouse is not neatly arranged so that the warehouse seems narrow.  Likewise, the warehouse line or line layout is not clear, the placement of finished goods for both export and local products is placed in one location with the material (Completely Knock Down / CKD) in one warehouse location, there is no barrier between the goods belonging to one customer and another.  other things, goods are placed to close the road area or forklift lanes and warehouse doors, and goods that have entered earlier are closed with new incoming goods, thus hampering the process of handling goods.  With limited storage space, companies are required to use space effectively and efficiently so that storage activities are not hampered and can find the best layout that is more effective and efficient and does not hamper the delivery process.  The method used in warehousing management is a shared storage approach in which the products that have the most shipping frequency and the ones that frequently go in and out are brought close to the entrance to minimize the distance of material handling movement.  The results of the shared storage approach can minimize the material handling distance of the proposed layout is 1386 m, while the previous condition, the initial layout distance was 1900 m. Has a total range of 514 meters of total mileage. This means that the layout of the proposal could shorten the mileage through which warehouse workers take goods.
