Judul: Analysis of Production Efficiency and Maintenance System of Modern Rice Milling Plant Perum BULOG Kendal
Abstrak: Modern Rice Milling Plant (MRMP) merupakan sarana penggilingan modern yang terintegrasi mulai dari pengeringan, penyimpanan gabah dan pengolahan padi menjadi beras hingga gudang beras. Permasalahan downtime mesin yang tinggi dapat menyebabkan produktivitas menurun. Oleh karena itu analisis efisiensi produksi dan sistem pemeliharaan (maintenance) diperlukan untuk menilai kinerja produksi dan mesin. Penelitian ini bertujuan untuk menganalisis tingkat produktivitas kerja mesin dryer dan Rice Milling Unit (RMU) melalui perhitungan nilai Overall Equipment Effectiveness (OEE), analisis six big losses, analisis fishbone diagram, dan identifikasi sistem pemeliharaan melalui penerapan Total Productive Maintenance (TPM), dan memberikan alternatif solusi berupa rekomendasi perbaikan untuk meningkatkan kinerja produksi dan mesin. Terdapat tiga faktor utama dalam perhitungan OEE yaitu ketersediaan mesin dan peralatan(availability), kinerja (performance), dan kualitas (quality). Rata-rata pencapaian nilai OEE pada mesin dryer dan Rice Milling Unit (RMU) di Modern Rice Milling Plant (MRMP) BULOG Kendal masih dibawah standar dari perusahaan kelas dunia yaitu sebesar 85%. Analisis six big losses menunjukkan bahwa reduce speed losses merupakan faktor dominan yang menyebabkan rendahnya nilai OEE pada mesin dryer dan RMU. Reduce speed losses terjadi karena kinerja mesin yang kurang optimal. Untuk mengatasi masalah, maka perlu dilakukan perbaikan pada mesin dryer dan RMU seperti membuat jadwal pergantian komponen mesin, menambah teknisi pemeliharaan mesin untuk mempercepat penanganan kerusakan mesin, dan melakukan peningkatan terhadap penerapan TPM sehingga dapat tercapainya efisiensi produksi dan perusahaan mampu memproduksi beras dengan optimal. Kata kunci: efisiensi, modern rice milling plant, overall equipment effectiveness, total productive maintenance, Modern Rice Milling Plant (MRMP) is a modern integrated milling facility starting from drying, grain storage and processing of paddy into rice to rice warehouses. The problem of high machine downtime can cause decreased productivity. Therefore an analysis of production efficiency and maintenance systems is needed to assess production and machine performance. This study aims to analyze the work productivity level of the dryer machine and the Rice Milling Unit (RMU) by calculating the Overall Equipment Effectiveness (OEE) value, analyzing six big losses, analyzing fishbone diagrams, and identifying maintenance systems through the implementation of Total Productive Maintenance (TPM), and provide alternative solutions in the form of proposed improvements to improve production and engine performance. There are three main factors in calculating OEE, machine and equipment availability, performance, and quality. The average OEE score for dryer machines and Rice Milling Units (RMU) at BULOG Kendal's Modern Rice Milling Plant (MRMP) is still below the standards of world-class companies, which is 85%. The analysis of six big losses shows that reduced speed losses are the dominant factor causing the low OEE value on the dryer and RMU machines. Reduced speed losses occur due to less than optimal engine performance. To overcome this problem, it is necessary to make improvements to the dryer and RMU machines such as making a schedule for replacing machine components, adding machine maintenance technicians to speed up handling machine damage, and making improvements to the application of TPM so that production efficiency can be achieved and the company is able to produce rice optimally.

Abstrak: Modern Rice Milling Plant (MRMP) Lampung merupakan infrastruktur modern pengolah beras yang baru saja beroperasi untuk mengolah beras premium. Namun, saat ini diketahui produktivitas produksi beras premium masih rendah dan informasi mengenai efektivitas rangkaian mesin MRMP Lampung juga masih kurang. Oleh karena itu, perlu dilakukan pengukuran Overall Equipment Effectiveness (OEE) untuk mengetahui seberapa baik mesin moden ini bekerja. Six Big Losses adalah enam kerugian yang harus dihindari oleh setiap perusahaan yang dapat mengurangi tingkat efektifitas suatu mesin. MRMP Lampung memiliki empat stasiun atau line produksi utama yaitu: line intake gabah, line pengeringan, line penggilingan, dan line pengemasan, pada penelitian ini pengukuran nilai OEE dan Six Big Losses. Rata-rata pencapaian OEE pada line intake gabah bernilai 48.27% yang disebabkan oleh Defect Losses, Rata-rata pencapaian OEE pada line pengeringan bernilai 62.01% yang disebabkan oleh Idle and Minor Stoppage Losses, pencapaian ini belum memenuhi standar JIPM. Rata-rata pencapaian OEE pada line penggilingan (RMU) bernilai 63.57% yang disebabkan oleh Idle and Minor Stoppage Losses, pencapaian ini juga belum memenuhi standar JIPM. Rata- rata OEE pada line pengemasan sudah baik dan memenuhi standar JIPM dengan pencapaian sebesar 94.26%., Modern Rice Milling Plant (MRMP) Lampung is a modern rice processing infrastructure that has just started operating to process premium rice. However, currently known that the productivity of premium rice production is still low and information regarding the effectiveness of the Lampung MRMP machine series is lacking. Therefore, necessary to measure Overall Equipment Effectiveness (OEE) to find out how well these modern machines work. Six Big Losses are six losses that must be avoided by every company can reduce the level of effectiveness of machine. MRMP Lampung has four main production stations or lines, namely: grain intake line, drying line, milling line, and packaging line. In this study, OEE and Six Big Losses values were measured. The average OEE achievement at the grain intake line is 48.27% by Defect Losses, the average OEE achievement at the drying line is 62.01% caused by Idle and Minor Stoppage Losses, this achievement does not meet JIPM standards. The average OEE achievement on the milling line (RMU) is 63.57% caused by Idle and Minor Stoppage Losses, this achievement also does not meet JIPM standards. The average OEE on the packaging line is good and meets JIPM standards with an achievement of 94.26%.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
