Abstract

Salah satu sumber energi alternatif yang menjanjikan adalah biomassa. Biomassa mengacu pada bahan organik, di mana bahan organik ini pada umumnya berasal dari tumbuhan maupun hewan. Adapun bahan organik ini termasuk limbah pertanian, limbah kayu, jerami, limbah makanan, dan banyak lagi. Dalam konteks ini, penggunaan biomassa sebagai sumber energi dapat menjadi solusi yang menarik. Salah satu keunggulan biomassa adalah ketersediaannya yang melimpah di wilayah pedesaan. Dengan memanfaatkan biomassa ini, desa-desa dapat memperoleh sumber energi yang terbarukan dan dapat diperbaharui secara berkelanjutan. Adapun metode yang tim penulis gunakan untuk menyusun artikel ini adalah dengan metode studi pustaka. Setelah meneliti beberapa jurnal terkait, tim penulis mendapatkan hasil yang menarik. Ternyata, biomassa cenderung efektif untuk digunakan sebagai energi alternatif pembangkit listrik di wilayah pedesaan. Hal ini sangat didukung mengingat mayoritas penduduk desa bekerja sebagai petani dan peternak. Maka, secara keseluruhan, penggunaan biomassa sebagai sumber energi alternatif pembangkit listrik di wilayah pedesaan memiliki potensi untuk menjadi solusi yang ramah lingkungan dan berkelanjutan. Bahan baku biomassa mudah didapat dari limbah pertanian atau sampah organik. Penggunaan energi biomassa juga dapat mengurangi ketergantunglran terhadap energi berbahan fosil, sehingga dapat meminimalisir dampak lingkungan dari penggunaan bahan bakar fosil.

Abstract

Fatigue is an important factor in ergonomics because it can affect the work ability of human resources. The term work fatigue leads to the condition of workers who are weakened to complete their work, resulting in a decrease in work capacity, endurance and work productivity. Work fatigue that occurs needs to be given special attention by the company in order to avoid hazards and risks that endanger workers and ongoing operational activities. One activity that has hazards and risks is driving. Driving fatigue is one of the factors causing accidents in the transportation sector so that it provides a high mortality rate. Therefore, this research was conducted at Mikrotrans JakLingko Koperasi Purimas Jaya to analyze the factors of work shifts, tenure, age and sleep quality that cause fatigue using the Subjective Self Rating Test method from the IFRC. The results showed that work shifts and fatigue had a value of 0.043 < 0.05, tenure and fatigue 0.874 > 0.05, age and fatigue 0.071 > 0.05 and sleep quality and fatigue 0.150 > 0.05. It is concluded that work shift and fatigue have a significant relationship. Meanwhile, tenure, age and sleep quality have no relationship to fatigue.

Abstract

Resort Hotel Anyer is a star hotel with a resort type which is located close to several other star hotels which offer various different service quality standards. Resort Hotel Anyer has not been able to compete with existing competitors, resulting in income and the number of tourist visits to Resort Hotel Anyer becoming very unstable due to limited market share. Therefore, it is necessary to design a company strategy to find out what strategy is most suitable to be implemented. The methods used in this research are the IFE matrix, EFE matrix, IE matrix, SPACE matrix, SWOT matrix, and QSPM. The research results showed 16 strengths, 5 weaknesses, 10 opportunities and 7 threats. The position of the Anyer Hotel Resort, in the IE matrix, is in quadrant IV in the grow and build category and in the SPACE matrix it is in quadrant I in the aggressive category.

Abstract

Bintang CCTV store is a retail business that specializes in digital security, namely CCTV cameras. Bintang CCTV store is a result of the development of Bintang Komputer store, which is also located in Jagakarsa. After one year of operation, sales have not been stable, so a feasibility analysis is needed to assess the financial, non-financial, sensitivity, and Business Model Canvas aspects. The results of the financial aspect calculations were applied to three sensitivity conditions: optimistic, best, and pessimistic. Under optimistic conditions, the business is considered feasible with a NPV of Rp236,483,715, a PP of 2 year and 7 months, a PI of 1.51, an IRR of 78,8%, and a BEP of Rp173,641,626. Under best conditions, the business is also considered feasible with a NPV of Rp71,108,423, a PP of 4 years and 4 months, a PI of 1.23, an IRR of 23,8%, and a BEP of Rp173,641,626. However, under pessimistic conditions, the business is considered not feasible with a NPV of -Rp116,747,029, a PP is longer than the target, a PI of 0.93, an IRR of -15,9%, and a BEP of -Rp116,747,029. The non-financial aspects include management and organization, market and marketing, and technical and operational aspects. The Business Model Canvas classifies nine business elements based on the results of interviews.

Abstract

PT Mitra Sarana Mahadana is a company engaged in the sale of PVC ceilings, PVC ceiling trim, and hollows. However, the products stored at this company are stored randomly, causing product damage when product pick-up is carried out. In addition, this random placement also causes a long search time to find a particular product so that time causes product retrieval to be inefficient and product damage causes storage to be ineffective. Therefore, improvements are needed using dedicated storage methods, class-based storage, and proposed improvements simulated using Arena. This study resulted in a conclusion in the form of a dedicated storage method succeeded in reducing the travel distance by 46.56% from the actual distance of 9,056.57 meters to 4,840.05 meters. From the simulation results, it was found that the dedicated storage method succeeded in reducing the product transfer process time by 79.85% from the actual time of 130 seconds to the proposed condition time of 26.2 seconds.

Abstract

The XYZ factory is a factory that produces GRC Krawangan products. From observations, there are inefficiencies caused by disorganized layout, irregular material handling, unnecessary movements, and waiting times. The identified waste can be analyzed for its causes and minimized to enhance production efficiency through Lean Manufacturing approaches. This research employs methods such as Value Stream Mapping (VSM), Value Stream Analysis Tool (VALSAT), Process Activity Mapping (PAM), Failure Mode Effect and Analysis (FMEA), and Fault Tree Analysis (FTA). The research results revealed a ranking of the 7 wastes, with the highest being waste in transportation, unnecessary motion, and waiting. These wastes were then assessed using VALSAT, and PAM emerged as the selected tool. Subsequently, FMEA data collection identified 7 sub-wastes exceeding Critical RPN. These sub-wastes were further analyzed using FTA. Based on the waste analysis through various methods, improvement proposals were made. These include enhancing facility layout with BLOCPLAN software, increasing the layout score from 0.72 to 0.99. The research also suggests the use of adjustable desk aids, successfully reducing the REBA score from 9 to 6. Additionally, in PAM, total activity improvement amounted to 129 by eliminating 9 activities, leading to a decrease in activity time from 98,862.69 to 97,495.72 seconds
