Abstract

PT. Perkebunan Nusantara VII (Persero) merupakan salah satu Badan Usaha Milik Negara (BUMN) yang mengemban tugas untuk mewujudkan ketahanan di bidang perkebunan. Kapasitas pengolahan pabrik rencana saat ini adalah 50 Ton/Tandan Buah Segar/Jam. Akan tetapi, periode 2014 – 2019 rata – rata kapasitas olah pabrik hanya sebesar 38,13 Ton/TBS. Salah satu permasalahan yang dihadapi adalah kurangnya pasokan air untuk proses pengolahan, sementara potensi air yang dikelola berasal dari embung yang tersedia di dekat lokasi pabrik. Penelitian ini dilaksanakan untuk mengkaji neraca air pada embung serta mengusulkan untuk melakukan optimalisasi fungsi embung dengan caramembandingkansimulasi perhitungan kapasitas tampung embung sebelum dan sesudah normalisasi kedalaman embung. Hasil analisis dan perhitungan data menunjukkan bahwa konsumsi uilitas pengolahan sawit menjadi CPO saat ini adalah sebesar 1,73 ton air/TBS dimana kondisi normal membutuhkan sebesar 1,8 ton air/TBS. Perhitungan kapasitas tampung embung eksisting adalah sebsar 50.428 m3 dengan ketinggian air rerata di kolam sebesar 1,5 m  hanya mampu mencukupi produksi rata – rata selama 23,67 hari setiap bulannya sehingga tidak dapat memenuhi target produksi yang diharapkan. Usaha optimalisasi dari 4 (empat) embung eksisting dengan mengembalikan kedalaman embung menjadi 3 m menghasilkan kapasitas tampung rata – rata sebesar 195.762 m3 atau terjadi peningkatan sebesar 389,85% dari kapasitas tampung embung rata – rata saat ini yaitu sebesar 49.953,13 m3.

Abstract

Water is the largest natural resource in Indonesia and it is easy to use in its utilization. Water that can be utilized directly from the river or by collecting rainwater in a tando pond orreservoir and then flowing it to turn a turbine. To utilize the available water resources, thegovernment always builds and maintains its facilities and infrastructure, including bybuilding dams. Unpredictable rain intensity, especially in the Lampung area, can cause a lackof optimal water release. If the release of water is not optimal, then the need for water willnot be obtained optimally, but the presence of water in the reservoir cannot always be fulfilledwhen it is needed. The Batu Tegi Dam is an important dam for the needs of the surroundingwatershed and Tanggamus. When building a system, optimization is an importantcomponent. System design can reduce processing time, among others through optimization.Mathematical functions are usually used to describe optimization problems. The process ofmaximizing or minimizing the objective function while taking into account the existingconstraints is known as optimization. This calculation uses the Microsoft Excel 2021application. By analyzing the optimal release discharge, as well as displaying the optimaldischarge value in 2022 using the Genetic Algorithm method. This method is the expertise offlexibility and accuracy when maximizing complex systems. The results of this study obtainoptimal discharge before and after using the Genetic Algorithm (GA) method with a timeseries of 2018 to 2022, making a discharge discharge curve in 2022. Keywords: Genetic Algorithm, Dam, Release Optimization
