"[Kenaikan tarif listrik PLN sebesar 13% perdua bulan pada tahun 2014 berdampak bagi PT.Semen Padang yang mengandalkan pasokan utama dari PLN. Dampak kenaikan tarif adalah peningkatan biaya belanja listrik ke PLN untuk produksi semen sebesar 33,4%. Penelitian ini bertujuan untuk membangun model untuk mengetahui kelayakan pembangunan captive power plant pada PT. Semen Padang dengan tetap berpegang pada prinsip “good quality of energy at the lowest possible cost” untuk menurunkan belanja listrik. Model yang dibangun adalah metode deterministik dan probabilistik dengan simulasi Monte Carlo. Penelitian ini berhasil membuktikan hipotesis bahwa pembangunan captive power plant layak untuk dilakukan dikarenakan nilai dari NPV > 0 dan IRR > MARR, tetapi dari hasil perhitungan probabiitas resiko menunjukkan probabilitas mendapat NPV > 0 adalah 59.10% sementara probabilitas mendapat IRR > MARR adalah 55,78%, sehingga sebaiknya tidak dibangun pada saat ini menunggu menguatnya nilai tukar rupiah terhadap dollar Amerika.

Increasing of electricity tariff by 13% per two months in 2014 will impact to PT Semen Padang that rely on the main supply from PLN. The impact of the tariff increase is the increase in the cost of electricity to PLN for cement production by 33,4%. This research objective to build a model to determine the feasibility of the construction of captive power plant at PT. Semen Padang by sticking to the principle of "good quality of energy at the lowest possible cost" in order to reduce electricity cost. The model which will be built is deterministic and probabilistic methods by Monte Carlo simulations. This research was able to prove the hypothesis that the development of captive power plant is feasible because the value of NPV> 0 and IRR> MARR, but from the calculation of risk indicates taht the probability to get NPV > 0 is 59.10% while the probability to get IRR> MARR is 55.78% , so it should not be built at the time being waiting for the strengthening of the rupiah against the US dollar., Increasing of electricity tariff by 13% per two months in 2014 will impact to PT

"PT. XYZ merupakan salah satu BUMN yang memiliki trend outstanding biaya listrik yang meningkat dari tahun ke tahun. Penelitian ini bertujuan untuk menganalisis faktor – faktor penyebab outstanding transaksi pencatatan biaya listrik di PT XYZ, risiko yang timbul dan tindakan perbaikan yang harus dilakukan oleh Manajemen Perusahaan PT. XYZ. Penelitian dilakukan dengan melakukan pengumpulan data internal perusahaan dan wawancara semi-struktur kepada informan sebelum dan setelah perusahaan mengimplementasikan Shared Services. Metode penelitian menggunakan metode kualitatif dengan pendekatan studi kasus eksploratif. Berdasarkan hasil penelitian, terdapat tujuh risiko, yaitu understated expense, over budget, over payment, kerugian perusahaan, abnormal balance account payables (saldo debit), tidak tepatnya pencatatan, dan reputasi perusahaan menurun. Hasil penelitian menunjukan bahwa risiko mengalami penurunan setelah dilakukan mitigasi risiko menggunakan model bisnis Shared Services dan teknologi Robotic Process Automation (RPA). Penulis menyarankan agar PT XYZ menerapkan roadmap Enterprise Risk Management (ERM) dalam proses bisnis, dan secara konsisten melakukan pengelolaan proses bisnis pencatatan biaya listrik sesuai dengan kebijakan dan prosedur yang telah ditetapkan.

PT. XYZ is one of the state-owned enterprises that has a trend of outstanding electricity costs that increase from year to year. This study aims to analyze the factors that cause outstanding transactions for recording electricity costs at PT XYZ, the risks that arise and corrective actions that must be taken by the company management of PT. XYZ. The research was conducted by collecting company internal data and semi-structured interviews with informants before and after the company implemented Shared Services. The research method uses qualitative methods with an exploratory case study approach. Based on the results of the study, there are seven risks, namely understated expense, over budget, over payment, company losses, abnormal balance of account payables (debit balance), inaccurate recording, and declining company reputation. The results showed that the risk decreased after risk mitigation was carried out using the Shared Services business model and Robotic Process Automation (RPA) technology. The author suggests that PT XYZ implement a roadmap in business processes, and consistently manage the business process of recording electricity costs in accordance with established policies and procedures."

"Penelitian ini bertujuan untuk mengurangi biaya listrik sektor industrimelalui penambahan daya PLTS sebagai sumber energi alternatif. Berbagaiskenario load management dibandingkan untuk mendapatkan keuntungan optimaldengan mempertimbangkan penggunaan baterai, Time of Use (ToU) Tariff, waktuoperasional pabrik serta Feed in Tariff (FIT). PLTS tanpa baterai lebihmenguntungkan dibandingkan PLTS dengan baterai karena mampu menghemattagihan listrik sebesar 24% dengan IRR 10,7%, NPV sebesar Rp.36,4 Miliar sertamampu mengembalikan investasi hanya dalam 9 tahun. Selain itu, PLTS jenis inimemiliki biaya perawatan tahunan yang rendah dan secara teknis lebih mudahuntuk diterapkan.

This research aimed to reduce industrial electricity cost by injecting PV

system as an alternative power generator. Various load management scenarios

were compared to obtain optimum savings by considering battery usage, the time

of use (ToU) tariff, factory working hours and feed in tariff (FIT). Most profitable

result was shown by PV system without battery with 24% of cost reduction,

10,7% of IRR, Rp.36,4 Billion of NPV and able to recoup investment within 9

years only. Besides, this type of PV had low annual maintenance cost and easier

to be implemented."

"Salah satu upaya untuk mengatasi krisis energi adalah mengurangi ketergantungan terhadap sumber energi fosil dengan cara memanfaatkan sumber energi alternatif. Salah satu energi alternatif yang dapat digunakan adalah energi angin. Energi angin dapat dimanfaatkan pada pembangkit listrik tenaga angin. Pembangkit listrik tenaga angin merupakan suatu metode untuk membangkitkan energi listrik dengan cara memutar turbin angin yang dihubungkan ke generator, kemudian energi listrik yang dihasilkan oleh generator disimpan dalam elemen penyimpan energi listrik (baterai). Energi listrik yang tersimpan dalam elemen penyimpan akan dibebankan kepada beban beban rumah tangga yang berdaya rendah sehingga dengan pembangkit ini akan terlihat penggunaan sistem pembangkit listrik tenaga angin ini dengan turbin angin berporos vertikal tipe savonius.

One effort to overcome the energy crisis is to reduce dependence on fossil energy sources by utilizing alternative energy sources. One of the alternative energy that can be used is wind energy. Wind energy can be utilized in wind power. Wind power is a method for generating electrical energy by rotating wind turbines connected to generators, and electrical energy generated by the generator is stored in the elements of electrical energy storage (batteries). Electrical energy stored in the storage element will be charged to expense burden of households with low power so that this generation will be seen savings on residential electricity costs. "
