Abstract

Indonesia is blessed with around 27.510 MWe of geothermal resources. Amongst the numbers, some resources are identified as small-scale geothermal resources. The development of small-scale geothermal resources is quite challenging either to government or private developers due to their low selling price that varies from USD 6.50 cent/kWh to USD 9.76 cent/kWh depending on the location and capacity. The challenges can be multiplied in the case of the electricity produced from a geothermal power plant that located isolated grid, where the electricity is unable to be transmitted to another load areas. Therefore, the electricity production will be limited to only serve the demand in the island that consequently will limit the revenue from electricity sales. This study analyzes the financial aspect of a binary geothermal power plant with gross installed capacity of 5 MW located in isolated island. The analysis shows the power plant will be financially feasible when the electricity selling price is over USD 30 cent/kWh that will generate 12% of IRR which is assumed as feasible target for this project. Furthermore, if environmental benefit is included the project can be feasible at lower selling price of USD 25 cent/kWh.

Abstract

Kecemasan bisa terjadi pada siapa saja, orang dewasa maupun remaja. Salah satu contoh kecemasan pada siswa adalah kecemasan akademik. Saat merasa cemas siswa akan melakukan hal-hal seperti perilaku menyimpang, kurangnya konsentrasi saat proses pembelajaran, sering mengeluh, perasaan was-was, sering ke toilet karena merasa tidak nyaman, jantung berdebar ketika akan menghadapi tugas, tidak percaya diri dalam menghadapi tuntutan akademik yang lebih tinggi dan lain sebagainya. Penelitian ini bertujuan untuk menyelidiki pengaruh kecemasan terhadap hasil belajar siswa kelas X pada pelajaran fisika, melalui pendekatan kuantitatif, populasi dalam penelitian ini adalah seluruh siswa SMA Inshafuddin Banda Aceh. Pengambilan sampel dalam penelitian ini menggunakan teknik Purpposive Sampling, yaitu dengan mengambil sampel pada siswa kelas X IPA I dan X IPA II yang berjumlah 68 siswa. Instrumen yang digunakan dalam penelitian ini adalah angket kecemasan dan dokumentasi untuk hasil belajar siswa pada pelajaran fisika. Untuk mengetahui pengaruh antar variabel menggunakan teknik analisis regresi linear sederhana diperoleh hasil Fhitung = 7166,570 > Ftabel = 3,986 bahwa model regresi adalah linear, kemudian dilakukan uji korelasi r = -0,83. Selanjutnya dilakukan uji hipotesis t dua arah sehingga diperoleh thitung > ttabel, dengan demikian Ha diterima sehingga dapat disimpulkan bahwa terdapat pengaruh negatif signifikan antara kecemasan terhadap hasil belajar siswa kelas X pada pelajaran fisika di SMA Inshafuddin.

Abstract

The independent learning curriculum is implemented in 2021/2022 and not all schools have implemented this independent curriculum so that there are still few references, especially at the junior high school level. Physics teachers in implementing the Independent Curriculum at SMPN 1 Susoh Aceh Barat Daya, SMPN 3 Susoh Aceh Barat Daya, and MTsN 1 Aceh Barat Daya face obstacles, namely teachers do not have experience with the concept of the Independent Learning Curriculum. This study aims to find out what are the difficulties of science teachers in implementing the independent curriculum and how science teachers overcome them in implementing the independent curriculum. This study uses a descriptive research method with a qualitative research method approach. The results of the study indicate that the difficulties of science teachers in implementing the independent curriculum that occur in the application of Physics subjects at SMPN 1 Susoh Aceh Barat Daya, SMPN 3 Susoh Aceh Barat Daya, and MTsN 1 Aceh Barat Daya are in planning, implementing learning and assessment. Science teachers' efforts to overcome this include attending meetings with (KKG), attending training, coordinating with fellow teachers, teachers do not require students to memorize but must understand the material, teachers write the material on the board and make student worksheets, students take notes, continue class projects at home, look for references on assessments and attend training on implementing the Independent Learning Curriculum.

Abstract

Tofu industrial wastewater contains a high level of chemical oxygen demand (COD), which may cause negative impacts if not treated before being discharged into the environment. Filtration is one of the simple and effective methods for COD removal in tofu industrial wastewater, utilizing filtration media such as sand and activated carbon. The objective of this research is to evaluate the performance of spent coffee grounds (SCG) activated carbon and river sand as filtration media in COD removal from tofu industrial wastewater. The research was carried out using a dual media filtration unit composed of SCG activated carbon and river sand, with media thicknesses of 15 cm and 30 cm, respectively. The results show that the combination of SCG activated carbon and river sand as filtration media can reduce the COD level in tofu industrial wastewater from 928 mg/L to 307 mg/L (66.92%), although it still does not meet the quality standard (300 mg/L). Based on the findings, it can be concluded that the combination of SCG activated carbon and river sand has the potential to lower COD levels in tofu industrial wastewater, but further improvement is required to enhance its effectiveness.
