Abstract

Electrical energy is a primary need at this time, which almost all human activities require electricity. The electrical energy we use today is a conversion from other energy, partly derived from fossil energy, which is energy that cannot be renewed and will run out if it is continuously explored and exploited. Solar energy is a renewable energy source that has the potential to be converted to electrical energy using solar panels or so-called photovoltaics. Photovoltaic has a drawback in its use, namely the output value is very dependent on environmental conditions. To maximize the power efficiency between the photovoltaic output and the power to be used by the load, a method is needed, namely Maximum Power Point Tracking (MPPT). In the application of this MPPT DC-DC Zeta converter is used with a hill climbing algorithm to achieve the value of the output voltage and current at maximum power. With this method, it is expected that MPPT control is reliable and easy to apply. In this study, the type of photovoltaic module used is the 60 Wp monocrystalline type with sampling data once an hour from 09.00 - 17.00 WITA, the tracking speed data obtained by the modified hill climbing algorithm is 0.142 seconds on average with an average efficiency of 99.969 %.

Abstract

Resulting output voltage is not constant due to light intensity and surface temperature of the solar panels. To overcome the output voltage of solar panels that tends to fluctuate, is to add a DC-DC converter to the output side of the DC-DC Converter used in this study is the Quadratic Boost Converter type which has a role to increase the output voltage of the monocrystalline type solar panel so that it remains constant at 24V DC. using Mamdani Fuzzy Logic Control as a method of controlling PWM switching. The results obtained from this study are that the quadratic boost converter can keep the output voltage of the solar panel constant at 24V, with low ripple voltage and overshoot. The Mamdani fuzzy logic method used can produce a constant output voltage value with a rise time of ± 5 seconds. The efficiency obtained from this converter hardware is quite good, ranging from 76% - 88%.

Abstract

Electrical energy has a very important role in the economic, industrial and social development of the community, this causes an increase in the demand for electrical energy in line with the increase in people's welfare, economic and industrial growth. On the other side, energy sources that are commonly used for power generation are increasingly expensive and limited in availability and cause environmental pollution. Based on these considerations, it is necessary to implement an energy management program to preserve energy resources and use energy effectively. Energy consumption intensity (ECI) is a term used to determine the amount of electrical energy consumption in a room. The calculation of the intensity of energy consumption carried out at the Tojo Una-una regent's office in Central Sulawesi consists of 3 buildings with 129 rooms, it was found that 7 rooms were categorized as quite efficient and wasteful.

Abstract

Energi matahari (solar) memberikan banyak manfaat bagi kehidupan manusia. Salah satu pemanfaatan energi surya yang dapat diimplementasikan adalah dalam bentuk Pembangkit Listrik Tenaga Surya (PLTS). Universitas Tadulako berkomitmen untuk melaksanakan PLTS secara mandiri. Salah satu upaya yang dilakukan adalah dengan memanfaatkan lahan yang luas sebagai lahan PLTS yang saling terhubung, yang sering disebut dengan PLTS on-grid atau grid-connected. PLTS on-grid merupakan sistem PLTS yang terhubung dengan jaringan distribusi PLN. Pada sistem ini, jaringan listrik PLN berperan sebagai penyalur atau penyambung arus listrik yang berasal dari panel surya yang disalurkan ke beban. Dari hasil pengukuran diketahui luas lahan kosong Universitas Tadulako menurut masterplan UNTAD sekitar 5 hektar. Melalui software PVSyst total daya yang dihasilkan oleh PV sebesar 5544 kWp dan total daya inverter sebesar 4620 kWac dengan total PV terpasang sebanyak 10080 panel. Panel tersebut terhubung dengan 42 inverter. Setiap satu unit inverter mempunyai 12 string dan setiap string pada inverter terdiri dari 20 panel surya. Dari hasil tersebut, investasi sistem PLTS di Universitas Tadulako diperkirakan mencapai Rp. 75.907.251.114,00.
