“…Metode CPM (Critical Path Method) adalah suatu metode yang bertujuan untuk menganalisis waktu dan biaya proyek melalui percepatan pekerjaan. Sebuah algoritma baru yang menggabungkan evaluasi diferensial yang ditingkatkan dan metode jalur kritis (CPM) berdasarkan strategi solusi terpisah multivariabel, diajukan untuk mencari solusi optimal global secara lebih efisien (Chen et al, 2015).…”

Perencanaan pembangunan proyek tentunya memerlukan analisis yang tepat dan sesuai dengan kebutuhan yang diinginkan. Kegiatan ini sangat dibutuhkan karena untuk mengukur berapa biaya yang akan dikeluarkan dan berapa kemampuan biaya untuk membangun proyek tersebut. Pembangunan jalan di Indonesia saat ini sedang berkembang pesat apalagi pada era sekarang ini. Keberhasilan ataupun kegagalan dari pelaksanaan proyek pembangunan jalan sering kali disebabkan kurang terencananya kegiatan proyek serta pengendalian yang kurang efektif sehingga kegiatan proyek tidak efisien. Pengoptimalan waktu pembangunan bertujuan untuk pencegahan keterlambatan proyek dan meminimalisasi biaya serta percepatan kegiatan proyek pembangunan. Pada proyek pembangunan jalan Tol Becakayu Seksi 1BC dengan menggunakan metode CPM terdapat jalur kritis dimana kegiatan pekerjaan tersebut adalah Pekerjaan pembebasan lahan, Pekerjaan pembangunan direksi kit dan gudang, Pekerjaan pondasi, Pekerjaan kolom, Pekerjaan stressing girder, Pekerjaan slab, Pekerjaan pelapisan aspal, Pekerjaan lain-lain dan Pekerjaan finishing. Perusahaan mendapatkan peluang sebesar 79.67 % untuk menyelesaikan proyek pembangunan jalan Tol Becakayu Seksi 1BC setelah melakukan pengolahan data dengan menggunakan metode PERT (Program Evaluation Review Technique).

Project management is a new thing with the development of two analytical techniques used for planning, scheduling, and decision making on projects to be carried out so that they can be carried out optimally and efficiently. These two analytical techniques are the Critical Path Method (CPM) and Project Evaluation and Review Technique (PERT). Network optimization for the project is very important for the production of with "Aeta" brand Bottled Mineral Water produced by drinking water company in Madiun. This optimization is carried out in order to find out the production schedule of bottled water, there are 4 packages produced namely cups, 1.5 L bottles, 600 ml bottles, and gallons. After scheduling using the Critical Path Method, ie bottled water production will be more profitable if more products are in Gallon packaging. Because the Gallon packaging will save time this happens because the Gallon packaging does not go through cardboard packaging.

Ventilation plays a key role in underground mining. It is essential due to the natural hazards and technological processes that come with the nature of mining. However, it is highly energy consuming and generates significant operating expenditures. Fan station parameters are selected based on the needs of a particular mine but mainly consider the requirements for the period of developed mining activities. When the period of mine decommissioning begins, the parameters of the main fan station often exceed its needs. In Poland, many mines have been closed in recent years. However, sometimes, due to the necessity of pumping underground water, it cannot be done thoroughly. In such a situation, it usually turns out that the parameters of the existing fan station significantly exceed the mine’s needs. The main fan stations are devoid of control systems, and even if they have them, they do not allow for a significant reduction of their volume flow rate. Modernising of the station to meet new requirements of the mine is expensive and time consuming. Solving the presented problem is possible by developing a fan station to replace main fans that are too big. The idea is easy to implement and consists of connecting it to an existing upcast shaft or downcast shaft, which will then be changed to upcast. The solution presented in the article has been implemented in two Polish coal mines and is in progress in a third mine. The examples presented in the article clearly show the energy benefits of replacing main fans that are too large.
