No full textFeasibility studies are essential tools used to assess the viability and potential success of a project or investment. These studies provide critical information that helps stakeholders make informed decisions by analyzing various factors such as costs, benefits, risks, and potential returns. One specific type of project that often undergoes feasibility evaluation is housing development. In many cases, the feasibility assessment of housing projects is typically conducted by estimating the number of units sold without necessarily examining actual sales data. This approach can lead to inaccuracies and misguided conclusions. To address this gap, our research aims to re-evaluate the investment feasibility of ongoing housing projects by incorporating actual sales data and predicting future sales figures. By doing so, we can provide a more accurate and reliable assessment of the project's viability. The findings from this re-evaluation indicate that the investment in housing development remains highly feasible. Key financial metrics support this conclusion: the project has a Payback Period (PP) of just 0.55 years, meaning the initial investment is recovered in a little over half a year. Additionally, the Net Present Value (NPV) stands at Rp 103,917,111,414, reflecting the project's substantial profitability. Furthermore, the Internal Rate of Return (IRR) is an impressive 81.73%, far exceeding typical investment benchmarks. Lastly, the Benefit-Cost Ratio (BCR) of 1.53 demonstrates that the benefits of the project significantly outweigh the costs, confirming its overall financial soundness. These results underscore the importance of using comprehensive data analysis in feasibility studies to ensure accurate and effective investment decisions

The Use of E-Modules to Improve Critical Thinking Skills of Physics Education Students
No full textCritical thinking skills are essential in physics education, particularly in understanding abstract concepts like wave functions in quantum mechanics. However, traditional teaching methods often fail to foster these skills effectively. This study explores the use of an interactive e-module titled Quantum Physics: Wave Function to enhance critical thinking skills among students in a physics education program. A quasi-experimental design was employed with an experimental group using the e-module and a control group following conventional methods. Pretest and posttest results showed a significant improvement in critical thinking skills for the experimental group (average increase: 26.30) compared to the control group (average increase: 11.70). Statistical analysis confirmed the e-module's effectiveness (t = 2.95, p = 0.01). The e-module fostered active participation, problem-solving, and independent exploration, demonstrating its potential to improve critical thinking and engagement in complex physics topics. These findings highlight the value of integrating technology into physics education to enhance learning outcomes
Viability of Entomopathogenic Fungi (Metarhizium anisopliae) in Residual Media Maggots and Pupa Shell Waste
No full textMetarhizium anisopliae is a fungus that acts as an entomopathogen, commonly used to control pest insects (Biological Control Agent). This saprophytic mushroom requires sufficient organic nutrients in the growth medium. Typically, rice or corn is used as the media; however, this poses a challenge as these grains are also consumed by humans as staple foods. Additionally, the price of rice and corn has been increasing steadily. Alternatively, organic materials like maggot residue and pupa shells are byproducts from maggot cultivation that contain high nutritional value but are not utilized optimally. This research aims to identify effective alternative media for the multiplication of Metarhizium anisopliae. The research method involved controlled, homogeneous, and sterile experimental conditions, using a completely randomized design with four treatments and six repetitions. The fungus showed a high conidia density in the control media (rice corn), measuring 15.5 x 108. In chicken manure, a high density of 14.4 x 108 was observed, while the media made from maggot residue and pupa shells showed very low densities of 2.08 x 106 and 6.25 x 106, respectively. This suggests the presence of antimicrobial peptides (AMP), fatty acids, various bacteria, and lignocellulose compounds in the maggot residue and pupa shells. Overall, the organic materials from maggot residue and pupa shells are not effective as growth mediums for the fungus Metarhizium anisopliae.Metarhizium anisopliae merupakan salah satu cendawan entomopatogen yang banyak digunakan dalam pengendalian hama serangga (Agen Pegendali Hayati). Cendawan ini memiliki sifat saprofit, sehingga membutuhkan nutrisi yang cukup pada media bahan organik agar dapat tumbuh. Media bahan organik yang umum digunakan adalah beras jagung. Namun, saat ini penggunaannya bersaing dengan manusia yang juga mengonsumsinya sebagai makanan pokok. Selain itu, harga beras jagung juga relatif terus meningkat. Media bahan organik residu maggot dan cangkang pupa merupakan limbah sisa hasil dari budidaya maggot yang tinggi kandungan nutrisi. Namun, masih belum dimanfaatkan secara optimal. Penelitian ini bertujuan untuk menemukan potensi media alternatif yang efektif dalam perbanyakan cendawan Metarhizium anisopliae. Metode penelitian yang digunakan adalah metode eksperimental dalam konidisi terkontrol, homogen, dan steril menggunakan Rancangan Acak Lengkap (RAL), dengan 4 (empat) perlakuan, dan ulangan sebanyak 6 (enam) kali. Cendawan Metarhizium anisopliae menunjukkan nilai kerapatan konidia yang tinggi pada media kontrol beras jagung yaitu 15,5 x 108. Media bahan organik kotoran ayam menunjukkan nilai kerapatan yang tinggi yaitu 14,4 x 108, sedangkan pada media bahan organik residu maggot dan limbah cangkang pupa menunjukkan nilai kerapatan yang sangat rendah yaitu 2,08 x 106 dan 6,25 x 106. Oleh karena adanya antimikroba peptide (AMP), asam lemak, beberapa kandungan bakteri dan senyawa lignoselulosa pada kedua media tersebut. Media bahan organik residu maggot dan cangkang pupa kurang efektif untuk digunakan sebagai media pertumbuhan cendawan Metarhizium anisopliae
