Judul: Analisis dan Desain Sistem Perencanaan Produksi dengan Macro VBA Excel pada Produksi Beras di MRMP Perum BULOG Subang.
Abstrak: Modern Rice Milling Plant (MRMP) Subang merupakan salah satu Unit Bisnis (UB) di bawah naungan Perum BULOG berupa pabrik penggilingan padi dengan infrastruktur modern. Hasil eksplorasi permasalahan yang terjadi di MRMP Subang yaitu pemenuhan permintaan beras yang belum optimal karena belum adanya perencanaan produksi yang dilakukan oleh perusahaan. Produta ini bertujuan untuk mendapatkan rekomendasi dan rancangan penyelesaian masalah terkait manajemen perencanaan produksi di MRMP Subang melalui aplikasi perencanaan produksi. Analisis perencanaan produksi diawali dengan melakukan forecasting permintaan beras dengan metode time series. Hasilnya digunakan untuk perencanaan produksi dengan merumuskan model goal programming karena mempertimbangkan beberapa tujuan yang ingin diselesaikan. Model perencanaan produksi diimplementasikan dengan analisis dan desain sistem menggunakan metode Framework for the Application of System Thinking (FAST) dengan data flow diagram dan use case diagram. Desain sistem dibuat bentuk fisiknya menggunakan Macro VBA Excel dan Excel solver di Microsoft Excel. Hasil analisis dan desain sistem perencanaan produksi dapat membantu memberikan rekomendasi penyelesaian masalah terkait perencanaan produksi beras di periode yang akan datang agar kegiatan produksi dapat lebih terencana. Hasil validasi sistem serta analisis sensitivitas menunjukkan bahwa aplikasi sudah layak digunakan. Sistem perencanaan produksi dapat diimplementasikan pada MRMP Subang dengan melakukan sosialisasi menggunakan modul penggunaan aplikasi dan video., Modern Rice Milling Plant (MRMP) Subang is one of the Business Units (UB) under the auspices of Perum BULOG in the form of a rice mill with modern infrastructure. The problems that occurred at MRMP Subang were fulfilling the demand for rice which was not optimal because there was no production planning carried out by the company. This project aimed to obtain recommendations and design solutions to problems related to production planning management at MRMP Subang. The method used with engineering design consists of five phases, namely the exploration phase, problem definition, ideation, prototype development, and validation. The analytical tools used were forecasting time series methods and goal programming models while the system design used the Framework for the Application of System Thinking (FAST) method with data flow diagrams and use case diagrams. System development into physical form using Macro VBA Excel and Excel Solver. The results of the analysis and design of the production planning system can help provide recommendations for solving problems related to rice production planning in the coming period so that production activities can be more planned. The results of system validation and sensitivity analysis show that the application is feasible to use. The production planning system can be implemented in the Subang MRMP by conducting socialization using application and video modules.

Judul: Design for Performance Improvement and Value Addition in Rice Supply Chain at Modern Rice Milling Plant Perum BULOG Subang
Abstrak: Modern Rice Milling Plant (MRMP) Subang merupakan perusahaan penggilingan padi yang mulai beroperasi pada bulan Oktober tahun 2022 sehingga belum pernah melakukan identifikasi terhadap kondisi rantai pasoknya. Proyek desain utama ini bertujuan mengidentifikasi situasional, kinerja, dan nilai tambah rantai pasok beras, merumuskan strategi peningkatan kinerja dan nilai tambah rantai pasok beras dan merancang ulang model rantai pasok baru. Analisis situasional rantai pasok menggunakan pendekatan Food Supply Chain Management (FSCM). Analisis kinerja rantai pasok menggunakan metode Supply Chain Operations Reference Digital Standard (SCOR DS). Nilai kinerja rantai pasok pada MRMP Subang dan mitra penyalur berturut-turut adalah 76,85% dan 68,54%. Nilai tambah dianalisis menggunakan metode hayami dan didapatkan nilai tambah sebesar Rp843.000/ton Gabah Kering Panen (GKP) atau sebesar 12,41%. Kinerja dan nilai tambah rantai pasok beras dapat ditingkatkan menggunakan model Analytical Network Process (ANP).Strategi peningkatan kinerja dan nilai tambah terpilih adalah penerapan sistem perencanaan produksi dan penerapan sistem jaminan mutu yang dimasukkan pada rancangan model rantai pasok yang baru., Modern Rice Milling Plant (MRMP) Subang is a rice milling company that started operations in October 2022 and has never identified its supply chain conditions. This major design project aims to identify the rice supply chain's situational, performance, and added value, formulate strategies to improve the performance and added value of the rice supply chain, and redesign a new supply chain model. The situational analysis of the supply chain used the Food Supply Chain Management (FSCM) approach. Supply chain performance analysis using the Supply Chain Operations Reference Digital Standard (SCOR DS) method. The supply chain performance scores for Subang MRMP and supply partners were 76.85% and 68.54%, respectively. The added value was analyzed using the Hayami method and obtained an added value of IDR 843,000/ton of Harvested Dry Grain (GKP) or 12.41%. The performance and value-added of the rice supply chain can be improved using the Analytical Network Process (ANP) model. The selected performance improvement and value-added strategies are the implementation of a production planning system and a quality assurance system incorporated in the design of the new supply chain model.

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.
