Abstract

The bin packing problem is a classic combinatorial optimisation problem that is widely used in various applications such as assembly line balancing, scheduling, and time-tabling. Metaheuristic algorithms can provide solutions to these problems faster than exact methods. Bees Algorithm, a metaheuristic algorithm inspired by the foraging activity of bees, is known for its performance in solving optimisation problems. To our best knowledge, this is the first use of the Bees Algorithm to solve a bin packing problem. In this paper, we use the basic Bees Algorithm to demonstrate near-optimal solutions and measure the accuracy of solutions to the one-dimensional bin packing problem. The algorithm procedure and parameter settings are set following the previous research. Benchmark datasets are used in the experiment, and accuracy is measured. The results indicate that the basic Bees Algorithm for bin packing problems and previous research on travelling salesman problems produce similar accuracy results.

Abstract

Forecasting broiler meat production is very important to avoid a deficit or lack of broiler meat availability so that the nutrition of the people of Cilegon city can be fulfilled. The Cilegon Livestock Service has a record of fluctuating chicken production every year. Data were obtained from the distribution of broiler production in the city of Cilegon. However, this does not guarantee that the amount of chicken production in Cilegon City follows the demand. For this reason, it is necessary to conduct research using the dynamic system method. The purpose of this study was to identify the factors that affect the availability of chickens, create a broiler availability system through a dynamic system, and calculate the level of chicken availability in the city of Cilegon. The results of the dynamic system simulation show that the research shows that in 2022-2026 the demand for broilers is experiencing an increasing trend, but the production of broilers is in deficit. In the years 2022-2026, the demand for chicken meat is increasing and the availability is insufficient with a very significant difference. Therefore, through this research, the Cilegon City Government must increase the production of broilers in Cilegon City by increasing the number of breeders and opening up import opportunities from other cities so that the needs of broilers in Cilegon City can be fulfilled.

Abstract

Manusia merupakan makhluk sosial yang memiliki kebutuhan untuk berkumpul dan bersosialisasi bersama orang lain. Salah satu tempat berkumpul yang sering digunakan sebagai tempat berkumpul adalah restoran. Restoran dapat menjadi tempat menikmati makanan dan berkumpul kepada semua orang. Pada akhir tahun 2019 dunia dikejutkan dengan munculnya virus baru Covid-19 yang memiliki tingkat penyebaran yang sangat cepat. Sehingga diberlakukan PSBB pertama di kota Cilegon yaitu pada tanggal 10 September 2020 selama 2 minggu. Restoran XYZ juga mengikuti penutupan layanan dine in saat berlakunya PSBB. Pada 1 Juni 2020 pemerintah Indonesia memberlakukan new normal, maka restoran diperbolehkan kembali membuka layanan dine in dengan kebijakan protokol kesehatan yang sangat ketat disertai dengan pembatasan jumlah konsumen. Dengan diberlakukannya new normal maka restoran XYZ dapat membuka kembali layanan dine in pada tanggal 8 Juni 2020 dengan penerapan protokol kesehatan, social distancing, dan pembatasan waktu dibukanya layanan dine in. Penelitian ini bertujuan untuk mengetahui pengaruh penerapan protokol kesehatan, pengetahuan tentang Covid-19 dan minat beli terhadap keputusan pembelian dalam melakukan dine in. Metode pengumpulan data menggunakan kuesioner dengan populasi masyarakat Cilegon yang telah melakukan dine in di restoran XYZ minimal satu kali sejak protokol kesehatan diterapkan. Sampel yang digunakan berjumlah 205 sampel. Penelitian ini menggunakan Structural Equation Modelling (SEM) dengan bantuan software LISREL 10.3. Hasil dari penelitian ini adalah penerapan protokol kesehatan dan pengetahuan tentang Covid-19 berpengaruh positif tetapi tidak signifikan terhadap keputusan pembelian dalam melakukan dine in, sedangkan minat beli berpengaruh positif dan signifikan terhadap keputusan pembelian dalam melakukan dine in.

Abstract

University Y is currently building a business center building to support lecture activities. Construction of lecture buildings is a must, while construction work is the riskiest job among other jobs. The purpose of this study is to identify potential hazards and reduce workplace accidents in the construction of a business center building and a temporary rest area for workers. This research uses the hazard identification risk assessment and risk control (HIRARC) method, with data collection through observation, interviews, and taking pictures and photos. The results showed that there were 18 potential risks, with low at 33%, moderate at 28%, high at 17%, and extreme at 22%. Risk control can be carried out through technical engineering, administratively by making SOPs, elimination, replacement of tools, and the provision of some personal protective equipment (PPE) that does not yet exist. Supervision of the use of PPE, giving safety signs, and regular meeting activities in the project environment need to be carried out so that workers know the dangers that may arise from their work and be careful at work.

Abstract

In its business process, the company involves investors as other sources of capital or company financial sources. Therefore, investors are unlikely to stick with companies that have poor financial performance conditions. The purpose of this study was to analyze the financial performance of PT Gajah Tunggal Tbk in 2017 to 2020 based on the liquidity ratio. The data used in the form of secondary data, namely the company's financial statements for the 2017-2020 period. Analysis of the data used is the liquidity ratio which consists of the current ratio, quick ratio, and cash ratio. The results obtained from the analysis of the liquidity ratio at PT Gajah Tunggal Tbk seen that the company's financial condition was not optimal. This is because of the three ratios used, only the current ratio and the fast ratio are in good condition. Meanwhile, the cash ratio is in poor condition. The reason is, the company still often runs a deficit in meeting its short-term debt. In future research, it should be analyzed with other ratios such as profitability and solvency ratios so that financial conditions can be analyzed more broadly.

Abstract

RSIA Permata Serdang merupakan salah satu rumah sakit tipe C yang mengalami penurunan kunjungan pasien dan menerima banyak keluhan. Tujuan penelitian ini untuk menentukan faktor dominan dan tipe waste yang menjadi sumber ketidakpuasan pasien serta menentukan perbaikan dari waste kritis yang terjadi terhadap pelayanan rawat jalan RSIA. Penelitian ini menggunakan kerangka Six Sigma yaitu DMAIC (Define, Measure, Analyze, Improvement, Control). Tahapan penelitian dilakukan dengan menghitung nilai gap setiap atribut kepuasan pelanggan, menganalisis akar penyebab ketidakpuasan dan memberikan rekomendasi perbaikan lean healthcare untuk mereduksi pemborosan pada sistem pelayanan. Berdasarkan metode tersebut diperoleh waste kritis yaitu waiting, unnecessary inventory dan overproduction. Pengurangan dan eliminasi waste yang telah terindikasi dilakukan menggunakan Root Cause Analysis (RCA). Setelah itu, disusun action planning dari penyebab terjadinya waste tersebut dengan menggunakan Failure Mode And Effect Analysis (FMEA). Usulan perbaikan yaitu membuat loket khusus atau membuat loket tambahan untuk pasien yang menggunakan asuransi kesehatan serta perekrutan petugas pendaftran rawat jalan, mengalokasikan sumber daya dengan mencocokkan kapasitas yang tersedia, meninjau ulang jadwal praktek dokter, memaksimalkan penggunaan database pasien secara elektronik dan menerapkan visual management (kode warna) pada tiap rak penyimpanan rekam medis, membuat display tata letak ruangan serta membuat display penunjuk ruangan sehingga dapat meningkatkan kualitas sistem pelayanan.

Abstract

Energi sudah menjadi kebutuhan yang tidak dapat dipisahkan dalam kehidupan manusia. Saat ini, sumber energi masih didominasi oleh sumber daya yang tidak dapat diperbaharui (unrenewable resources) yang dapat habis seiring dengan waktu. Industri manufaktur, sebagai salah satu sektor yang mengkonsumsi energi dalam jumlah besar, dituntut untuk dapat melakukan konservasi energi dalam kegiatan operasionalnya. Penjadwalan dapat digunakan sebagai metode konservasi energi. Penelitian ini membahas penjadwalan banyak tujuan flow-shop untuk meminimasi biaya pemakaian listrik dan total tardiness. Kecepatan mesin dapat diubah untuk mengurangi atau menambah waktu proses sebuah job. Apabila waktu proses sebuah job dikurangi, maka job dapat selesai lebih cepat. Akan tetapi, mengurangi waktu proses sebuah job memerlukan energi yang lebih banyak. Oleh karena itu, akan muncul trade-off antara total tardiness dan konsumsi energi. Algoritma memetic multi-obyektif (MOMA) dikembangkan untuk memecahkan masalah multi-tujuan. Percobaan numerik dilakukan untuk mengevaluasi performansi MOMA menggunakan masalah yang dibangkitkan secara acak. Hasil dari percobaan numerik menunjukkan bahwa MOMA efektif dalam menyelesaikan masalah penjadwalan multi-tujuan flow-shop.

Abstract

Penelitian yang membahas antrian di apotek maupun bagian farmasi rumah sakit telah banyak dilakukan. Namun penelitian yang menggunakan shift kerja dan bertujuan mengurangi waktu menunggu sekaligus meningkatkan utilisasi pegawai masih belum banyak dilakukan. Penelitian sebelumnya telah mengusulkan penambahan jumlah pegawai dan perbaikan layout di sebuah apotek untuk meningkatkan service level dan mengurangi waktu antrian. Namun ternyata waktu menunggu proses peracikan obat menjadi lebih lama karena masih dilakukan oleh satu orang. Dalam penelitian ini akan diusulkan pengaturan shift kerja sehingga total waktu menunggu menjadi lebih singkat dan utilisasi pegawai meningkat. Skenario yang diusulkan adalah penerapan dua shift kerja dimana masing-masing shift menggunakan satu orang pegawai (skenario 1) dan penggunaan dua orang pegawai pada jam sibuk serta penerapan dua shift kerja di luar jam sibuk (skenario 2). Berdasarkan hasil penelitian, diketahui bahwa skenario usulan 1 unggul dalam utilisasi hari Jumat dan Sabtu serta waktu menunggu obat, sedangkan skenario awal unggul dalam rata-rata waktu mengantri. Skenario usulan 2 hanya unggul dalam utilisasi hari Senin–Kamis. Oleh karena itu, apabila ingin memperoleh tingkat utilisasi terbesar dan waktu menunggu obat yang paling singkat, maka sebaiknya menerapkan skenario usulan 1. Namun apabila ingin memperoleh rata-rata waktu mengantri pelanggan yang paling singkat, maka sebaiknya menggunakan skenario awal.
