Judul: Design of layout Production Room and Equipment at the Purple Potato Chips Production House in Ciloto Village
Abstrak: Unit usaha keripik ubi ungu Desa Ciloto merupakan unit usaha yang memproduksi keripik yang saat ini mulai banyak digemari masyarakat, sebagai makanan ringan (snack). Terdapat beberapa masalah pada tata letak ruang produksi yaitu terdapat dwifungsi ruang produksi dengan pesantren, ketidaksesuaian allowance, area kerja terpisah, adanya backtracking, dan higienitas tempat produksi. Permasalahan tersebut menyebabkan produksi keripik ubi ungu belum maksimal dan belum memenuhi standar CPPOB (Cara Produksi Pangan Olahan Yang Baik). Penelitian ini bertujuan memberikan rekomendasi usulan tata letak kepada rumah produksi keripik ubi ungu Desa Ciloto. Metode yang digunakan dalam perancangan ulang tata letak pada penelitian ini adalah BLOCPLAN (Block Layout Overview with Layout Planning). Hasil dari penelitian berupa prototipe tata letak ruang produksi sejumlah 5 departemen/ruang produksi keripik ubi ungu dengan luas total ruang produksi sebesar 53,63 m2 total jarak penanganan bahan 78,48 m dan efisiensi tata letak sebesar 0,87., The Purple Sweet Potato Chips business unit in Ciloto Village is a business unit that produces chips which are now starting to be popular with the public, as snacks. There are several problems in the layout of the production room, namely there is a dual function of the production room with a boarding school, inappropriate allowances, separate work areas, backtracking, and hygiene of the production site. This problem causes the production of purple sweet potato chips has not been maximized and has not met the CPPOB standard (Good Processed Food Production Methods). This study aims to provide recommendations for the layout of the purple sweet potato chips production house in Ciloto Village. The method used in redesigning the layout in this study is BLOCPLAN (Block Layout Overview with Layout Planning). The results of the study were in the form of a prototype production room layout of 5 departments/rooms for purple sweet potato chips production with a total production area of 53.63 m2, a total material handling distance of 78.48 m and a layout efficiency of 0.87.

Judul: Layout Design of Production Facilities at Mashed Potato and Potato Flour Production Unit in Modoinding
Abstrak: Perancangan pengembangan unit produksi kentang tumbuk dan tepung kentang di Kecamatan Modoinding, sebagai tindak lanjut dari riset adaptif program UPLAND, menjamin keberlanjutan bisnis. Tahap awal pengembangan memerlukan kajian tentang susunan fasilitas produksi di dalam unit untuk mencapai efisiensi produksi, terutama dalam alur berurutan dari proses dan bahan-bahan. Penelitian ini bertujuan untuk memberikan rekomendasi tata letak untuk Unit Produksi Modoinding. Metode desain tata letak yang digunakan adalah BLOCPLAN (Blok Layout Overview with Layout Planning). Hasil dari penelitian ini menyajikan tata letak prototipe untuk fasilitas produksi, dengan memanfaatkan total luas area 137 m2 dengan 12 area kerja dan 1 fasilitas tambahan, menghasilkan jarak total penanganan bahan sebesar 149,25 m. Upaya ini bertujuan untuk meningkatkan efisiensi produksi dan berkontribusi pada kesuksesan jangka panjang program UPLAND., The design and development of a mashed potato and potato flour production unit in the Modoinding Subdistrict, as a follow-up to the adaptive research of the UPLAND program, ensures business sustainability. The initial phase of development requires a study of production facility arrangements within the unit to achieve production efficiency, particularly in the sequential flow of processes and materials. This research aims to provide layout recommendations for the Modoinding Production Unit. The layout design method used is BLOCPLAN (Block Layout Overview with Layout Planning). The results of this research present a prototype layout for production facilities, utilizing a total area of 137 m2 with 12 work areas and an additional facilities, resulting in a total material handling distance of 149,25 m. This effort aims to enhance production efficiency and contribute to the long-term success of the UPLAND program.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
