Abstract

In Indonesia, motorcycle ownership is more than other motorized vehicles. However, the more motorbikes are used, the more vehicle emissions are released. So we need transportation solutions that are more environmentally friendly and energy efficient such as electric motorbikes which can be obtained with a converter kit by still utilizing existing conventional motorbike parts as provided by PT. A B C. However, many challenges were encountered in the commercialization of the converter kit from PT ABC, such as limited and uncertain suppliers, limited introduction to the market, and unpreparedness of Human Resources in product management. This study aims to analyze the constraints on the commercialization process of converter kit products as a basis for designing supply chain engineering proposals and appropriate business engineering. Based on the analysis of TRL and Goldsmith, it shows that the product is at TRL 8 or has fulfilled the requirements, but still has various obstacles. Based on the SWOT analysis, the company still has several shortcomings due to limited market interest, marketing strategies implemented, and price volatility. The results show that there is a business strategy design using the Business Model Canvas method to accelerate technology commercialization, one of which is through the expansion of existing partnership and marketing systems.

Abstract

Pengabdian kepada Masyarakat (PkM) berlokasi di Kabupaten Magetan, Jawa Timur, wilayah yang memiliki potensi Energi Baru Terbarukan (EBT) yang melimpah dan memiliki rencana investasi pada bidang elektrifikasi. Namun, adopsi-difusi teknologi elektrifikasi dan EBT dari masyarakat masih rendah, diantaranya dapat ditunjukan dengan rendahnya pemanfaatan energi surya dan rendahnya elektrifikasi kendaraan listrik. Solusi yang ditawarkan melalui PkM ini adalah mengembangkan simulator adopsi-difusi teknologi penyim­pan­an energi dan kendaraan listrik untuk media pembelajaran akses energi yang berkelanjutan bagi masyarakat. Metode pelaksanaan PkM dilakukan melalui: merancang media pembelajaran; memasang di taman refugia; menyusun modul dan pelatihan; pendampingan pengelolaan; serta peng­ukuran tingkat penerimaan. Sistem alat peraga yang dikembangkan terdiri dari: 1. etalase PLTS Atap, 2. Stasiun Penukaran Baterai Kendaraan Listrik Umum (SPKLU), 3. sepeda motor listrik, dan 4. smart farming). Media pembelajaran dapat digunakan untuk learning by doing dan selanjutnya dievaluasi perseps­inya terhadap kemudahan akses teknologi energi terbarukan. Pelak­sanaan PkM diharapkan menurunkan “chasm” atau jurang hambat­an adopsi tekno­logi dan masyarakat dapat menerima keberadaan inovasi teknologi. Berdasarkan survei sebelum dan sesudah kepada pengunjung, terlihat ada­nya peningkatan pemahaman akan pentingnya akses energi berkelanjutan yang signifikan dibuktikan dengan uji wilcoxon signed rank dan ditunjukkan kemanfaatannya dari nilai Benefit Cost Ratio (BCR), dimana hasil perhitungan menunjukkan nilai 4,57 sehingga layak diterapkan (BCR > 1,0).

Abstract

The usage of advertising as a medium for marketing products/services is used by various businesses to increase profits. The advertising medium mainly used is billboards, which still use fossil energy as an energy source. The Indonesian government's 2060 Net Zero Emission Program promotes using renewable energy (RE) as an energy source, such as photovoltaic (PV) as electrical energy from solar heat. As with RE, the development of PV still has problems in products and business, but PV is ready to be used as an energy source to reduce electricity bill costs. The business idea of PV installation in the advertising company sector emerged to support the government program Net Zero Emission, making advertising companies "green jobs" and absorbing human resources from vocational schools. Business conceptual design with value chains, business model canvas, and lean canvas expected can provide an overview of business opportunities with EBT for Indonesia that are environmentally friendly and energy independent.

Abstract

In Indonesia, construction accidents have occurred during the construction of bridges and elevated roads, peaking in 2017. The lifting of girder beams has failed in several construction projects, and the formwork has failed during pier construction. The reasons for these work accidents are human and equipment factors, which caused material losses and loss of life. A risk assessment model for bridge construction work accidents in construction projects is proposed in this paper, with the work breakdown structure (WBS), risk breakdown structure (RBS), analytic hierarchy process (AHP), and rating being integrated to assess the risk of bridge construction work accidents. This model is expected to improve safety in bridge construction by providing effective safety planning, especially in the accident risk assessment process. The study results indicate that the WBS and RBS can outline and explain the identification of construction safety risks for bridges and provide insight into the interrelationship of construction phases and the potential risks. The relationship between the WBS and RBS is created in the form of a coupling matrix, and we identify the potential risky activities at each phase and the corresponding construction phases. The AHP can be used to calculate the weights and priorities of the WBS and analyze the magnitude of the risk index for its related risky activities; then, the rating method can be used to analyze the risk index. Girder and diaphragm installation work involves a high risk of workers falling during the erection of girders. Doi: 10.28991/CEJ-2025-011-01-010 Full Text: PDF

Abstract

Operasi pasar murah minyak goreng curah dimaksudkan untuk menstabilkan harga dan membantu menjaga ketersediaannya di masyarakat. Akan tetapi, terkadang penentuan jumlah minyak goreng curah yang dijual di operasi pasar juga belum direncanakan sehingga operasi pasar tidak sesuai sasaran. Tujuan dari artikel ini adalah menentukan lokasi operasi pasar yang strategis atau merupakan titik terdekat dari lima kecamatan dan kuantitas minyak goreng yang dibutuhkan untuk tercapainya operasi pasar dengan harga yang diinginkan dan mencapai stabilisasi harga. Metode yang digunakan untuk menentukan lokasi operasi pasar adalah metode pusat gravitasi satu titik dan dua titik. Sedangkan untuk penentuan kuantitas minyak goreng yang dibutuhkan untuk operasi pasar ditentukan berdasarkan hukum keseimbangan pasar. Dengan pengkombinasian metode pusat gravitasi dan teori keseimbangan pasar dapat ditentukan lokasi dan kuantitas yang tepat untuk operasi pasar minyak goreng curah di Kota Surakarta. Implikasi manajerial dari model yang telah disusun dapat digunakan sebagai bahan pertimbangan bagi Dinas Perindustrian dan Perdagangan serta Tim Pengendali Inflasi Daerah (TPID) dalam menentukan lokasi dan kuantitas minyak goreng yang dibutuhkan untuk operasi pasar.Kata kunci : Hukum Keseimbangan Pasar, Metode Pusat Gravitasi, Minyak Goreng Curah, Operasi Pasar, Stabilisasi Harga

Abstract

Optimization of distribution routes is intended to allocate products to each high school in Surakarta as well as to choose the route that has the biggest time savings so that transportation costs can be optimized. The route currently used is quite long, so the time needed for the distribution is long. Determination of distribution routes using the Djikstra algorithm method is carried out on the distribution of LKS in CV ABC. The Djikstra algorithm method allows route optimization by taking into account vehicle capacity and number of demand from each customer. The data used are the distance between the warehouse to each high school and the distance between high schools, the quantity delivery per customer, and the vehicle capacity. The results of this study are that if implementing the shipping allocation by prioritizing the closest distance in advance it will save more travel time than applying the allocation used by this company. Based on the analysis, it was found that the optimal shortest route in the distribution of LKS to SMA was to save fuel needs by 1.21 liters and save transportation costs by Rp. 9075 or 17.89% of the initial transportationcosts.

Abstract

Procurement of machinery is a facilitation to overcome auction problems in accordance with the strategic plan of the Dinas TPHPKP to maintain and improve the quality or quality of commodities so as to increase the selling value. To carry out this facilitation with limited funds, other sources of subsidized funds are needed, the government needs tools to determine the nominal funding decision, the decision to place the machine, and the feasibility study of the model. Based on surveys, interviews, and previous research, the research data was processed using goal programming with Excel and ILOG CPLEX. This study chooses scenario three as the optimal scenario because the nominal subsidy of funds is smaller than scenarios one and two, but results in machine option decisions on each quality improvement function with a positive benefit deviation value of Rp. 20,014,000. This study succeeded in formulating a fund allocation model, determining five locations for placing machines and stating the feasibility of a fund allocation model with a Benefit Cost Ratio value of 1.49. Future research is expected to be able to consider the cost of energy consumption in the next use of the machine, consider the form of village assets as a candidate for placing the machine, and calculate other feasibility study parameters.
