Judul: Design of Layout Improvement in Food Canning Factory Sharing
Abstrak: PT Kita Satu Rasa sebagai suatu factory sharing memiliki tantangan untuk menyediakan produk pangan yang berkualitas melalui proses produksi yang lancar, aman, dan bermutu. Namun, dalam pengamatan langsung masih ditemukan permasalahan utamanya pada kondisi tata letak yang dapat memengaruhi kelancaran proses produksi. Permasalahan yang dihadapi PT Kita Satu Rasa pada tata letak pabrik pengalengan saat ini yaitu penempatan aktivitas yang terpencar, aliran backtracking, dan ketidaksesuaian allowance pada area kerja. Penelitian ini bertujuan mengidentifikasi kondisi awal tata letak pabrik pengalengan dan menganalisis perbaikan tata letak pabrik pengalengan. Perancangan perbaikan tata letak dilakukan dengan metode SLP (Systematic Layout Planning) dan algoritma CORELAP (Computerized Layout Planning). Tata letak usulan pada pabrik pengalengan menghasilkan peningkatan efisiensi jarak perpindahan material sebesar 28,89% berdasarkan hasil simulasi., PT Kita Satu Rasa, as a sharing factory, has challenges providing quality food products through a safe and quality production process. The problems PT Kita Satu Rasa faced in the current layout of the canning factory are the placement of scattered activities, backtracking flow, and inappropriate allowances in the work area. However, in direct observation, the main problem is still found in the layout conditions that will affect the safety and quality of the final product. This study aims to identify the initial conditions and analyze the improvement of the cannery layout. The layout improvement design uses the SLP (Systematic Layout Planning) method and the CORELAP (Computerized Layout Planning) algorithm. The proposed layout of the cannery increased the efficiency of the material transfer distance by 28.89%, based on the simulation results.

Judul: Perancangan Sistem Pencatatan dan Pengendalian Persediaan di Factory Sharing Pengalengan Pangan
Abstrak: Inventory control is very crucial in ensuring the smoothness of production activities in a company. PT Kita Satu Rasa as a food canning factory sharing needs to have a systematic inventory control system to cope with uncertain demand and improve their service performance. This study aims to identify the need for an inventory control system at PT Kita Satu Rasa and to design an inventory control system that is able to meet the company's needs. The inventory control system is designed with the aim of maintaining the availability of cans so that the company will always be able to meet customer’s demand. The method used are the determination of safety stock and reorder point as a reference for the precise order time to the can supplier. The system is designed on Microsoft Excel software and tested for feasibility and suitability to meet company needs through usability testing, simulation, and interview. The results of usability testing show that the system is classified as very feasible with an acceptance percentage of 90%. Through simulation, the system is proven to be able to prevent stock outs compared to the method used by the company. The system is well received by the company and its implementation is expected to contribute to the improvement of the company’s performance and service as a canning service provider for MSMEs.

Judul: Distribution and Diversity of Ectoparasite Mites on Geckos in Indonesia
Abstrak: Data on the diversity and dispersal of parasitic mites on house geckos in Indonesia are very scarce. In this work, the distribution and diversity of mites living on three species of house geckos, namely Cosymbotus platyurus, Hemidactylus frenatus, and H. garnotii collected throughout Indonesia, has been elaborated. Geckos and mites were captured and immediately preserved in 70% ethanol. Whole mount of the mites was prepared by clearing in lactophenol followed by mounting on polyvinyl lactophenol solutions. The SEM preparation was conducted to examine the detail morphological characters of the mites. The results showed that among 448 individuals of geckos, 221 geckos were infected by Geckobia mites. Prevalences of C. platyurus, H. frenatus, and H. garnotii infested by mites were 14.8%, 50.69%, and 79.6%, respectively. Three different spesies of Geckobia (G1, G2, and G3) could be differentiated; and based on similarities of their morphological characters to ones described in published literatures, Geckobia G2 is Geckobia glebosum and Geckobia G3 is Geckobia bataviensis while G1 could not be identified to the species level. The highest mean intensity of Geckobia G1 infestation was found on H. garnotii (I=7.0), G. glebosum infestation on H. frenatus (I=3.5), and G. bataviensis infestation on H. garnotii (I=11.8). In general, C. platyurus was infested by the least number of mites. Geckobia G1 were found living on the skin folds on the claws, G. glebosum were found mainly on the body and thigh, and G. bataviensis were found on almost all parts of the host’s body. Geckobia mites are distributed randomly throughout Indonesian Archipelago, following the pattern of distribution of their hosts. So it is concluded that Geckobia G1, G. glebosum, and G. bataviensis are sympatric.
