Abstract

Bandar Lampung merupakan kota besar di Indonesia yang akan berkembang menjadi kota metropolitan. Perkembangan kota dapat dipercepat dengan pembangunan infrastruktur pelayanan publik. Pengembangan transportasi umum seperti Bus Rapid Transit (BRT) di Kota Bandar Lampung diharapkan dapat meningkatkan ketertarikan masyarakat untuk menggunakan transportasi umum sehingga dapat menekan penggunaan kendaraan pribadi untuk mengurangi tingkat kemacetan dan kecelakaan lalu lintas. Pengoperasian BRT memerlukan adanya fasilitas penunjang, seperti halte. Pembangunan halte yang kurang baik mengakibatkan bertambahnya permasalahan transportasi. Masyarakat sebagai target pengguna menjadi enggan untuk menggunakan BRT karena  kesulitan saat akan memanfaatkan fasilitas tersebut. Tujuan penelitian ini adalah menentukan jumlah dan lokasi halte BRT di sepanjang rute Rajabasa-Sukaraja di Kota Bandar Lampung sehingga dapat memberikan akses yang layak ke halte terdekat kepada semua penumpang dengan jumlah halte yang minimum, tetapi dapat memenuhi semua titik permintaan di sepanjang rute (coverage area). Penentuan lokasi dan jumlah halte di sepanjang rute I BRT dilakukan dengan mengidentifikasi lokasi bangkitan yang mempunyai tingkat permintaan relatif tinggi dan kandidat lokasi halte yang memenuhi kriteria. Lokasi halte terpilih ditentukan dengan metode Set Covering Problem. Hasil perhitungan menyimpulkan terdapat 19 lokasi halte terpilih di sepanjang rute. Dalam penelitian ini juga dilakukan analisis penentuan lokasi halte ketika pemerintah memiliki keterbatasan anggaran pembangunan halte.

Abstract

Coconut sugar is one of the leading commodities in Banyumas City, coconut sugar and it is derivative processing can make a high contribution to the development of the local economy of the community. This can be seen from the history of the production of coconut sugar whose trend is always increasing, in 2013 the production of coconut sugar was 206,026 tons / day, in 2014 it increased to 240 tons / day and in 2015 the production reached 250 tons / day. This study aims to find an area of improvement for the design of tree climbing aids that are in line with the expectations of the nira hikers in the Cilongok Banyumas City. In carrying out their work, the loudspeakers did not have much safety equipment, in a day, the loudspeakers had to climb 40 trees from morning to evening. The average height of each coconut tree that is climbed is around 20 until 30 meters. This study aims to design coconut climbing aids for the nira hardener with a quality function deployment (QFD) approach. In the process of retrieving data, the researcher identifies the desires of consumers, a questionnaire that has been determined and contains attributes in accordance with the quality plan that has been determined in the framework of the thought distributed to the subject. The way to find out the user anthropometry data is by measuring height, body dimensions, age, weight and length of work, so that we can obtain a reference for designing coconut tree climbing aids that are in accordance with the expectations of the palm fruit pusher.

Abstract

GNP Snack company has problems in making raw material inventories which are sometimes not enough for 0.5 tons of cassava chips to fulfill demand. This will affect the production process carried out every day. Production needs per day 1 - 1.5 tons of production of cassava chips. The company benefits of GNP Snack are not optimal because it only produces an average profit per month of Rp. 2,000,000 therefore the right formula is needed to overcome this problem using the Branch and Bound Method and the Genetic Algebra Method. The calculation results from the branch and bound method show an increase in profits in December 2018 of Rp. 2,018,992 to Rp. 2,531,467 or a 25% increase, in January 2019 amounting to Rp. 2,247,488 to Rp. 4.247.620 or an increase of 89%, and in February 2019 Rp. 1,290,661 to Rp. 1,299,020 or experiencing a 1% increase and the results of calculations using the genetic algorithm method show an increase in profits in December 2018 of Rp. 2,018,992 to Rp. 2,555,477 or a 27% increase, in January 2019 Rp. 2,247,488 to Rp. 2,655,551 or an increase of 18%, and in February 2019 Rp. 1,290,661 to Rp. 2,810,316 or 118% increase.
