Judul: Analisa dan Desain Sistem dari Mobile Digital Business Traceability pada Pabrik Makanan.
Abstrak: Interaksi bisnis secara digital dalam traceability, mencangkup identifikasi, dokumentasi, dan penelusuran, dilakukan oleh aktor bisnis yang ada dalam rantai pasoknya. Perusahaan X, salah satu produsen biskuit multinasional, memiliki traceability yang sudah ditunjang Business Planning and Control System (BPCS). Walaupun sudah mencangkupi upstream dan downstream rantai pasok, traceability yang dimiliki oleh perusahaan masih dirasa kurang efektif. Hal ini dilihat dari hasil evaluasi yang dilakukan perusahaan melalui prosedur mock recall. Penelitian dengan metode analisa proses bisnis menggunakan Business Process Model and Notation (BPMN) terhadap sistem traceability, akan menemukan titik permasalahan traceability dalam prosedur mock recall. Hasil yang didapat menunjukkan bahwa traceability yang dimiliki masih kurang efektif karena terdapat aktivitas yang dilakukan secara manual, serta memakan waktu yang banyak. Oleh karena itu pada tahapan selanjutnya, dilakukan sebuah pengembangan desain sistem mobile traceability. Sistem ini dikembangkan dengan perhitungan cosine similarity, serta dilakukan verifikasi model dan validasi black box. Berdasarkan verifikasi dan validasi sistem terhadap kebutuhannya, menunjukkan sistem mobile traceability mampu meningkatkan efektivitas traceability perusahaan, serta dapat diterapkan dalam rantai pasok internal.

Judul: Analysis and Design of Mobile Traceability System for Frozen Meat Quality Surveillance at PT X
Abstrak: The quality surveillance process at PT X involves many activities. It makes QA/ QC inspectors unable to focus on the documentation process and traceability, especially on frozen meat products produced at PT X. Manual documentation and non-integrated system also hurdle to establishing efficient traceability operations. This research aims to analyze the necessary process of quality surveillance activity along each stage of PT X products, design components of the traceability system, prototype system components, and evaluate system performance in terms of verification and validation. This research designed a traceability architecture with a one-step-forward and one-step-back approach and analyzed the workflow using BPMN and UML diagrams. The traceability activity and documentation involve collecting the supplier's material information, conducting incoming checking, processing checking, outgoing checking, and summarizing the result to the traceability system to provide product information and history. The application's functionalities are documentation, manual and QR code tracking, and tracing. The mobile traceability system has been validated and verified towards the performance and behavior components, and the results were running well. Hence this mobile traceability system could be implemented as a traceability tool at PT X.

Judul: Lejeuneaceae Subfamily Ptychanthoideae (Hepaticae) in  West Java
Abstrak: Subfamily Ptychanthoideae of the family Lejeuneaceae (Hepaticae) in West Java is still poorly known. Publications on this subfamily are out of dated and written in the 19th or early of 20th century. The last taxonomic treatment of Ptychanthoideae of West Java was in 1933, many species names have changed since then. Studies on Ptychanthoideae of West Java are urgently needed. Studies on the Ptychanthoideae were based on the specimens collected from West Java. A total number of 361 of specimens deposited in the Herbarium Bogoriense (BO), Herbarium Biotrop (BIOT), Gottingen Herbarium (GOET) and Bangi Herbarium (UKMB) were examined, those are old and several recent specimens collected in West Java. Recent collections were made from Telaga Warna, Ciater, Gunung Halimun Salak National Park, Cibodas Botanical Garden, Bodogol Education Center and Conservation (Gunung Gede Pangrango National Park), University of Indonesia Campus Depok, including several collections from Banten Province. Twenty four species of Lejeuneaceae subfamily Ptychanthoideae are known from West Java, belonging to 8 genera namely Acrolejeunea (Spruce) Schiffn. (2 species), Archilejeunea (Spruce) Schiffn. (1 species), Lopholejeunea (Spruce) Schiffn. (10 species), Mastigolejeunea (Spruce) Schiffn. (3 species), Ptychanthus Nees (1 species), Schiffneriolejeunea Verd. (1 species), Spruceanthus Verd. (2 species) and Thysananthus Lindenb. (4 species). Two new records of Ptychanthoideae: Mastigolejeunea indica Steph. and Thysananthus minor Verdoorn are reported for Java. A determination key to the species is presented including their descriptions and illustrations.
