Abstract

Intisari—Proyek Bendungan “Y” yang saat ini dikerjakan oleh PT. ABC terdiri dari dua aktivitas besar, yaitu Proyek Pabrikasi dan Proyek Instalasi. Saat ini proyek Pabrikasi sudah terselesaikan dan akan segera dilanjutkan Proyek Instalasi Komponen Hidromekanikal Bendungan “Y” yang berlokasi di Konawe, Sulawesi Tenggara. Berdasarkan data yang didapatkan dari Wawancara dengan Manajer Proyek, diketahui bahwa pelaksanaan Proyek Pabrikasi Bendungan mengalami keterlambatan 30 hari dalam pelaksanaannya. Hal ini tentu menjadi sebuah peringatan sekaligus acuan bagi tim Proyek untuk memastikan bahwa untuk proyek lanjutan yaitu Proyek Instalasi Bendungan, jangan sampai terjadi keterlambatan seperti yang terjadi pada proyek sebelumnya. Tujuan dari penelitian ini adalah untuk membuat perencanaan dan penjadwalan Proyek Instalasi Komponen Hidromekanikal Bendungan “Y” menggunakan pendekatan Critical Path Method (CPM). Metode tersebut ditujukan untuk menganalisis aktivitas kritis yang dapat menjadi acuan untuk mengetahui durasi total proyek keseluruhan, dimana pada aktivitas kritis tersebut tidak boleh ada keterlambatan. Berdasarkan hasil penelitian, diketahui bahwa Proyek Instalasi Komponen Hidromekanikal Bendungan “Y” memiliki jumlah aktivitas sebanyak 58 aktivitas, dan 29 diantaranya tergolong dalam aktivitas kritis yang tidak memiliki waktu longgar (slack time) untuk terjadinya penundaan atau keterlambatan. Total durasi Proyek Instalasi Komponen Hidromekanikal Bendungan “Y” secara keseluruhan yang diperoleh dari pendekatan CPM adalah 209 hari. Abstract—The “Y” Dam Project which is currently being carried out by PT. ABC consists of two major activities, namely Fabrication Project and Installation Project. At present the Fabrication project has been completed and will soon be continued by the "Y" Dam Hydromechanical Component Installation Project located in Konawe, Southeast Sulawesi. Based on the data obtained from the Interview with the Project Manager, it is known that the implementation of the Dam Manufacturing Project has been delayed by 30 days in its implementation. This certainly serves as a warning as well as a reference for the Project team to ensure that for the follow-up project, namely the Dam Installation Project, there should not be delays as happened in the previous project. The purpose of this research is to plan and schedule the "Y" Dam Hydromechanical Component Installation Project using the Critical Path Method (CPM) approach. This method is intended to analyze critical activities which can be used as a reference to determine the total duration of the entire project, where there should be no delay in these critical activities. Based on the research results, it is known that the "Y" Dam Hydromechanical Component Installation Project has a total of 58 activities, and 29 of them are classified as critical activities that do not have slack time for delays or delays. The total duration of the overall “Y” Dam Hydromechanical Component Installation Project obtained from the CPM approach is 209 days.

Abstract

National Waste Management Information System shows that the amount of waste handled in Semarang City over the last three years has decreased with an average decline index of 1.06% per year. This is reinforced by the results of interviews with the Semarang City Environmental Service, that the handling of organic waste is still very limited because so far the handling has been more focused on an-organic waste. Therefore, it is necessary to evaluate supply chain performance to determine the constraints in organic waste management from upstream to downstream. Based on the research results using the Interpretive Structural Modeling (ISM) method through a focus group discussion process involving eight experts in the field of waste management, it is known that the supply chain performance for handling organic waste in Semarang City has 11 elements of constraints, which are divided into seven priority levels. The element with the highest priority is related to the availability of organic waste supplies, while the element with the lowest priority is technological innovation and the application of appropriate technology. Improving the performance of organic waste management supply chains should focus on elements according to priority.

Abstract

The accumulation of waste in Indonesia continues to increase over time, especially organic waste such as food waste. With the environmental problems being faced in Indonesia, PT. XYZ provides a solution so that this problem can be helped. PT. XYZ is a start-up that focuses on developing bioconversion technology using Black Soldier Fly (BSF) or maggot flies to process organic waste into high-value products. Supply chain flow is very important in the production process so that the flow from supplier to consumer is structured. Based on observations that have been made, several problems were found at PT. XYZ, namely that there are problems when collecting waste from partners A, B, C, D, and E because these partners are located far from each other so that the arrival of organic waste at PT. XYZ there was a delay. So that these problems can be overcome, it is necessary to approach the problem using the Supply Chain Management method so that the flow of the supply chain can be mapped so that the problem can be resolved. The results of this research obtained a cost reduction of 41.9% after implementing this solution.

Abstract

One of the work stations at PT. ABC is the Bioconversion work station (maggot enlargement). At this work station out were approximately 10 minutes for each biopond tank in 1 working day, with a total of 21 tanks. Workers often experience fatigue, especially in the back and neck areas. Therefore, an analysis was carried out on the fatigue factors experienced by workers. In this study, the method used to analyze worker posture is Rapid Entire Body Assessment (REBA). The REBA method is used to analyze overall body posture, and then the results will be tested using Ergofellow software. The results obtained from the investigation of worker posture at the bioconversion work station using Ergofellow software got a score of 6, with a moderate risk. This is because the biopond design is less than ideal. So, the proposed improvement given is to redesign the biopond design, with the hope that workers will no longer bend over when doing work and can minimize the risk of injury.

Abstract

Permintaan tinggi terhadap produk pangan mendorong Pabrik Tahu H. Fadhol untuk meningkatkan kualitas produknya dengan mengurangi jumlah produk cacat, yang saat ini rata-rata mencapai 29 tahu per hari. Jika kondisi ini terus berlanjut, dapat berdampak pada penurunan penjualan dan potensi kerugian. Untuk mengatasi permasalahan ini, digunakan metode Statistical Process Control (SPC) guna mengkaji sejauh mana efektivitas proses produksi yang berjalan serta mengidentifikasi kekurangan dan kelemahannya. Dari hasil kajian melalui diagram Pareto, tingkat kerusakan tertinggi adalah cacat kepotong dengan total 222 potong atau 37,88%, serta kerusakan hancur yang mencapai 364 potong atau 62,12%. Sedangkan capaian kemampuan proses (process capability) saat ini memiliki Cp sebesar 0,00 dengan indeks Cpk -1,54, yang menunjukkan bahwa proses produksi belum mampu menghasilkan tahu sesuai standar. Oleh karena itu, pabrik tahu H. Fadhol perlu mengendalikan proses produksinya agar mencapai nilai indeks kapabilitas Cpk minimal 1. Faktor utama penyebab produk cacat produksi tahu ini adalah aspek manusia dan metode. Rekomendasi perbaikan diperlukan seperti pelatihan SDM dan perbaikan metode kerja sebagai langkah peningkatan kualitas

Abstract

Intisari— Biaya distribusi produk yang masih cukup tinggi dan juga lokasi konsumen yang tersebar di berbagai wilayah Pulau Jawa menjadi sebuah tantangan yang cukup kompleks bagi UKM Mina Indo Sejahtera, agar dapat selalu memenuhi mayoritas bahkan seluruh demand dari konsumen potensialnya dengan biaya yang seefisien mungkin. Oleh karena itu, diperlukan sebuah desain jaringan supply chain yang optimal bagi UKM Mina Indo Sejahtera, agar seluruh konsumen dapat tetap terlayani dengan total biaya distribusi yang tetap efisien. Metode yang digunakan yaitu dengan menggunakan formulasi model matematis haversin dan juga Center of Gravity (COG) Adjusting. Koordinat lokasi yang dihasilkan terbukti mampu meminimalkan total jarak tempuh dan juga total biaya yang harus dikeluarkan UKM Mina Indo Sejahtera untuk mendistribusikan produknya ke seluruh market khususnya di Pulau Jawa. Hasil penurunan total jarak tempuh dan total biaya distribusi bulanan yang didapatkan melalui formula haversin dan metode COG Adjusting yaitu sebesar 22% dan 24%. Sehingga, apabila UKM Mina Indo Sejahtera memusatkan distribusinya pada lokasi baru tersebut, total jarak yang ditempuh ke seluruh pasar di Pulau Jawa dapat diminimalkan menjadi sejauh 1.720, 4 kilometer, dengan total biaya distribusi bulanan yang dikeluarkan hanya sebesar Rp Rp 11.736.455,-.. Abstract— The cost of product distribution is still quite high and also the location of consumers spread across various regions of Java Island is a fairly complex challenge for Mina Indo Sejahtera SMEs, in order to always meet the majority and even all demands from potential consumers at the most efficient cost possible. Therefore, an optimal supply chain network design is needed for Mina Indo Sejahtera SMEs, so that all consumers can still be served with efficient total distribution costs. The method used is by using a haversin mathematical model formulation and also Center of Gravity (COG) Adjusting. The resulting location coordinates are proven to be able to minimize the total distance traveled and also the total costs that must be incurred by Mina Indo Sejahtera SMEs to distribute their products to all markets, especially in Java. The results of the reduction in total mileage and total monthly distribution costs obtained through the haversin formula and the COG Adjusting method are 22% and 24%, respectively. Thus, if Mina Indo Sejahtera SMEs concentrated their distribution in the new location, the total distance traveled to all markets on Java Island could be minimized to 1,720, 4 kilometers, with a total monthly distribution cost of only Rp. 11,736,455,-.

Abstract

Kualitas layanan yang diberikan oleh sebuah perusahaan memiliki dampak besar terhadap tingkat kepuasan yang dirasakan oleh pelanggan. Ketika permintaan melebihi kapasitas yang ada, maka menimbulkan sebuah antrian. Sehingga dilakukan observasi pada SPBU Madukoro yang berlokasi di Jl. Jenderal Sudirman, Kota Semarang, pada kendaraan roda dua dan roda empat dengan mengabaikan jenis bahan bakar yang diisi dengan durasi pengamatan adalah 1 jam 15 menit. Ukuran performa yang dievaluasi meliputi jumlah antrian, waktu tunggu, dan nilai utilitas. Berdasarkan data yang diamati dan diolah menggunakan software Arena, hasilnya menunjukkan adanya antrian di server keempat dengan nilai utilitas yang hampir mencapai satu, menandakan tingkat kesibukan yang tinggi. Untuk meningkatkan efisiensi utilitas SPBU, disarankan merancang model perbaikan dengan menambah jumlah server di stasiun pengisian roda empat. Diharapkan penambahan ini dapat mengurangi nilai utilitas secara signifikan, menjadikannya di bawah angka satu. Perbaikan ini dapat berdampak pada kepuasan layanan konsumen saat langkah-langkah perbaikan dilakukan untuk mengatasi antrian.
