Abstract

BULOG (Indonesian Bureau of Logistics) Regional Division West Java is a state-owned public company that regulates and maintains a supply of rice in order to meet the needs of all Indonesian people. Currently, BULOG distributing rice from one SubDivre warehouse to another SubDivre warehouse (point-to-point system) so shipping costs are higher because the frequency of transportation used is higher and the total distance traveled is higher. To reduce the cost of distribution, we propose consolidation model based on hub and spoke network topology. Hub and spoke system is done by determining which points become the hubs and which points become the spoke. The problem in determining the location of the hub and spoke is known as the hub location problem. In this problem, single allocation p-hub median problem is used. We use AMPL to get the solution. Various number of hubs (5,6,7) are tested and evaluated based on total shipping cost. The number of hubs which gives the minimum total shipping cost is 7. Delivery system using the hub and spoke network model can reduce the total cost of distribution by 13,94%.

Used cooking oil or commonly called used minyak jelantah is classified as waste that can pollute the environment. For this reason, this waste cannot be disposed directly into the environment. One way to process this waste is to recycle it, or to make other products that are more useful and valuable, such as candles from used cooking oil. This community service activity consist of, socialization, training and assistance for making candles from used cooking oil for the ALMA Sisters community: Bhakti Luhur Orphanage, Bandung. This activity was successful according to plan and the most important thing is that through this activity, there was success which had a positive impact on service partners. This activity is considered useful and provides new knowledge for partners. Moreover, with the help of tools and materials for producing candles from used cooking oil provided, the partners were able to produce a thousand candles which were ready to be marketed. This service activity will not stop with training and mentoring activities only. In the future, the service team will continue to train and assist partners, especially in terms of marketing, packaging and production of other products using used cooking oil as raw material.

Abstract

Dunia pendidikan di Indonesia saat ini telah memasuki Kurikulum Merdeka, begitu juga dengan Sekolah Menengah Atas. Kurikulum Merdeka dinilai lebih sederhana dan fleksibel sehingga membuat siswa lebih aktif. Jenis-jenis aktivitas yang ada di dalam kurikulum ini lebih relevan dan banyak memberikan ruang untuk tugas berbasis proyek. Namun munculnya Kurikulum Merdeka ini menimbulkan permasalahan yaitu belum siapnya sekolah mengimplementasikan Kurikulum Merdeka khususnya dari segi mata pelajaran dan sumber daya. Begitu juga terjadi pada SMA Santa Maria 1, Bandung. Sekolah sangat membutuhkan kerja sama dengan Universitas dari segi keilmuan dan juga sumber daya.  Dengan perancangan Kurikulum Merdeka yang baik dengan didukung mata pelajaran berbasis proyek yang menarik minat siswa tentunya dapat meningkatkan kompetensi siswa dan menarik minat calon siswa. Oleh karena itu, Program Studi Teknik Industri Universitas Katolik Parahyangan hendak menjalin kerja sama untuk menghasilkan mata pelajar berbasis proyek, khususnya yang berhubungan dengan keilmuan Teknik Industri. Dengan demikian, selain membantu sekolah, Program Studi Teknik Industri UNPAR juga dapat meningkatkan eksistensi dan menarik minat siswa SMA untuk melanjutkan studi di Program Studi Sarjana Teknik Industri UNPAR. Tahapan dalam pelaksanaan ekstrakurikuler adalah identifikasi kebutuhan, perancangan produk alternatif, pembuatan prototype, dan evaluasi perancangan.  Hasil program ini adalah 9 disain produk, yaitu Level Up Hydration Bottle: Botol Minum bagi Gamers, Fan Moji: Cooler dan Power Bank handphone untuk gamers, Spila: Spidol lancar, mudah diisi ulang, hemat tinta dan penghapus papan tulis, Cuka: Alat cuci kuas lukis dan pengering kuas, Too AM: Bantal tangan leher untuk pelajar, Headset kipas dan noise reduction untuk gamers, Matras: Reusable notebook untuk menghemat kertas, Kacamata anti fog dan minyak, dan Cable organizer.

Abstract

Toko X merupakan sebuah perusahaan ritel di Kota Bandung yang bergerak di bidang industri kain. Toko X seringkali mendapatkan penurunan harga sementara dari pemasok. Penurunan harga ini dimanfaatkan oleh Toko X dengan membeli kain sesegera mungkin dan dalam jumlah yang lebih banyak dari biasanya. Persediaan yang lebih banyak menyebabkan adanya penambahan biaya penyimpanan dan semakin lama stok kain keluar dari gudang. Toko X ingin mengurangi waktu penyimpanan kain dengan menetapkan harga jual yang dapat memberikan profit optimal. Penelitian ini bertujuan untuk mengembangkan model persediaan pada periode penurunan harga sementara dari pemasok. Pengembangan model dilakukan dengan mempertimbangkan adanya diskon yang diberikan kepada konsumen pada periode yang terbatas. Parameter yang digunakan dalam pengembangan model terdiri dari harga jual kain, besaran penurunan harga sementara dari pemasok, biaya pembelian kain, biaya penyimpanan per unit, dan tingkat permintaan. Variabel keputusan yang digunakan dalam pengembangan model adalah besaran diskon dan jumlah kain yang terjual dengan harga reguler setelah diskon. Berdasarkan model matematika yang telah dirancang, diperoleh hasil bahwa adanya penurunan harga sementara dari pemasok, Toko X akan memesan sejumlah 59.069,96 yard kain. Kemudian, Toko X dapat menawarkan diskon sebesar 4,5% dengan harga jual kain sebesar Rp33.425,00 kepada konsumen agar waktu penyimpanan kain menjadi berkurang sebesar 20% menjadi elama 3,97 bulan danRp738.448.855,57.

Abstract

The Bhakti Luhur Alma Orphanage cares for people with disabilities—including those with physical, visual, and hearing impairments—who are homeless. The mobility of the orphanage residents is currently hindered by inadequate vehicle interiors. This study aims to identify the specific needs of the users, design vehicle interiors tailored to those needs, and evaluate the results. The method used is design thinking with inclusive principles, which includes the stages of understand, observe, define point of view, ideate, prototype, and test and reflect. In the understand and observe stages, seven main needs were identified, including ample space for movement, safety features, and self-reliance indicators. Through a concept scoring process of three design alternatives, a combined concept with the highest weighted score of 4.55 was selected. Some features of the final design include an ergonomic folding seat, a cross-body safety belt, a wheelchair restraint, audio/visual indicators, and guiding blocks. The design was evaluated by a mechanical engineer, a special education teacher, and a manufacturing expert. The evaluation indicated that the design is feasible and meets the needs of people with disabilities.
