Judul: Scale Up and Financial Feasibility Analysis of Low Cholesterol Salted Egg Production in Cilincing - North Jakarta
Abstrak: Telur asin merupakan produk olahan telur yang digemari oleh mayoritas masyarakat, tetapi mengandung kadar kolesterol melebihi batasan asupan harian bagi manusia. Produk telur asin rendah kolesterol menjadi jawaban atas keresahan masyarakat. Data permintaan telur bebek asin di 6000 gerai Indomaret Jabodetabek menunjukkan adanya kebutuhan pasokan harian minimum sebanyak 6000 butir/hari ke setiap gerai. Pemenuhan kebutuhan pasokan di gerai Indomaret dilakukan dengan penggandaan skala proses produksi dari skala laboratorium ke skala industri. Penggandaan skala menggunakan acuan proses produksi skala laboratorium sejumlah 120 butir dengan formulasi pemeraman selama 12 hari dalam larutan garam dengan perbandingan garam dan air adalah 1:2 yang dicampur bawang putih, sereh, dan daun jeruk cincang, perendaman dalam larutan soda 20% selama empat jam, dan pengukusan selama satu jam yang ditingkatkan skala proses produksinya menjadi kapasitas produksi skala industri sebesar 3000 butir. Peralatan yang digunakan pada titik fokus penggandaan skala proses adalah jacketed mixing tank, container box, rak pemeraman, tangki larutan soda, soda generator, dan steamer. Pendirian industri telur asin rendah kolesterol dikatakan layak dengan kriteria NPV sebesar Rp5.405.113.928, IRR sebesar 14,37%, Net B/C sebesar 1,18, dan PBP selama 1,5 tahun. Analisis sensitivitas menunjukkan penurunan harga jual dengan nilai switching value 16,68% memiliki pengaruh yang lebih sensitif terhadap perubahan arus kas dibandingkan peningkatan biaya operasional produksi dengan nilai switching value 30,32%., Salted eggs are a processed egg product favored by the majority of the population, but they contain a cholesterol level that exceeds the daily intake limit for humans. Low-cholesterol salted egg products provide an answer to the concerns of the community. Data on demand for salted duck eggs at 6000 Indomaret outlets in Jabodetabek shows a minimum daily supply requirement of 6000 eggs per day per outlet. The fulfillment of supply needs at Indomaret outlets is achieved by scaling up the production process from laboratory scale to industrial scale. Scaling up is based on a production process reference from the laboratory scale of 120 eggs with a 12-day curing formulation in a salt solution with a salt-to-water ratio of 1:2, mixed with chopped garlic, lemongrass, and citrus leaves, soaked in a 20% soda solution for four hours, and steamed for one hour. This scaled-up production process increases the industrial-scale production capacity to 3000 eggs. The equipment used at the focal point of the scaling-up process includes a jacketed mixing tank, container box, curing rack, soda solution tank, soda generator, and steamer. The establishment of a low-cholesterol salted egg industry is deemed feasible with an NPV criterion of Rp5,405,113,928, IRR of 14.37%, Net B/C of 1.18, and PBP of 1.5 years. Sensitivity analysis shows that a decrease in selling price with a switching value of 16.68% has a more sensitive impact on cash flow changes compared to an increase in production operational costs with a switching value of 30.32%.

Judul: Layout Design of Low Cholesterol Salted Egg Industry  in Cilincing - North Jakarta
Abstrak: Telur asin merupakan produk olahan telur yang cukup digemari masyarakat. Diketahui setiap harinya terdapat permintaan sebesar 6000 butir telur asin untuk gerai Indomaret di Jabodetabek. Industri telur asin rendah kolesterol di Cilincing, Jakarta Utara merupakan industri yang baru akan didirikan. Agar memperoleh izin edar produk dan sertfikasi NKV untuk unit usaha produk hewan, maka harus dilakukan perancangan tata letak yang sesuai dengan peraturan yang berlaku. Selain itu, perlu dilakukan perancangan tata letak untuk menjamin efisiensi proses dalam jangka panjang. Perancangan tata letak dilakukan dengan metode Systematic Layout Planning (SLP) dan algoritma Corelap. Perancangan tata letak dilakukan dengan memperhatikan aspek yang disyaratkan dalam CPPOB dan sertifikasi NKV. Hasil rancangan tata letak terdiri dari sembilan area produksi, tiga gudang, satu toilet, satu ruang ganti, dan satu kantor. Total luas yang diperlukan hasil penyesuaian sebesar 133,71 m2. Hasil simulasi menggunakan perangkat lunak Flexsim didapatkan total jarak perpindahan material sebesar 1111,76 m untuk kapasitas 3000 butir dan ketika kapasitas gudang telur dan gudang produk digunakan sepenuhnya., Salted eggs are a processed egg product that is quite popular among the community. It is known that there is a daily demand of 6000 pieces of salted eggs for Indomaret outlets in the Jabodetabek area. The low-cholesterol salted egg industry in Cilincing, North Jakarta, is a newly established industry. In order to obtain product distribution permits and NKV (Animal Products) certification for the animal product business unit, a layout design must be created in accordance with the applicable regulations. Additionally, a layout design is necessary to ensure long-term process efficiency. The layout design is carried out using the Systematic Layout Planning (SLP) method and the Corelap algorithm. The layout design takes into account the aspects required in the CPPOB and NKV certification. The resulting layout design consists of nine production areas, three warehouses, one toilet, one changing room, and one office. The total required area after adjustments is 133.71 m2. Simulation results using Flexsim software indicate a total material movement distance of 1111.76 m for a capacity of 3000 pieces when both the egg warehouse and product warehouse capacities are fully utilized.

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
