Judul: Rancang Bangun Sistem Total Productive Maintenance dengan Fuzzy Analytical Hierarchy Process
Abstrak: Total Productive Maintenance (TPM) adalah suatu sistem perawatan mesin yang melibatkan semua departemen termasuk produksi, pengembangan produk dan administrasi. Overall Equipment Effectiveness (OEE) merupakan metode alat ukur dalam penerapan sistem TPM guna menjaga mesin pada kondisi ideal dengan menghapuskan six big losses. Penelitian ini bertujuan untuk memperoleh nilai OEE mesin 5 in 1 sebagai dasar ukuran efektifitas mesin dan memperoleh strategi peningkatan OEE menggunakan fuzzy AHP. Rata-rata hasil evaluasi menggunakan Overall Equipment Effectiveness periode Oktober 2016-Desember 2016 menunjukkan nilai 49%. Berdasarkan hasil penilaian pakar menunjukan bahwa strategi terbaik peningkatan OEE adalah memperbaiki perencanaan produksi (0.4082), sehingga tujuan mesin bekerja efektif (0.3701). Aktor yang paling berperan adalah Departemen Produksi (0.3546) dan faktor yang paling berpengaruh yaitu keamanan (0.3225). Penelitian ini menyarankan strategi terbaik meningkatkan nilai OEE dengan memperbaiki perencanaan produksi yaitu menerapkan metode heijunka (tingkatan produksi) pada proses produksi serta single minutes exchange dies (SMED) pada proses setting up.

Judul: Analisis Overall Equipment Effectiveness sebagai Upaya untuk Meningkatkan Produktivitas di PT XYZ
Abstrak: Tingginya biaya pemeliharaan peralatan pada perusahaan umumnya disebabkan karena usaha perbaikan yang tidak menyentuh akar permasalahan dengan tepat. Overall Equipment Effectiveness (OEE) adalah salah satu metode yang dapat memberikan informasi untuk mengidentifikasi dan mengklarifikasi penyebab dari rendahnya kinerja suatu peralatan sehingga mampu menyelesaikan permasalahan dan menyentuh akar permasalahan dengan tepat. Penelitian ini bertujuan untuk mengidentifikasi tingkat produktivitas kerja mesin, menganalisis masalah yang menyebabkan adanya kerugian (losses), dan memberikan alternatif solusi bagi perusahaan untuk meningkatkan produktivitas pada lini 6 yang merupakan lini dengan jumlah masalah atau trouble yang tinggi. Terdapat tiga faktor utama dalam perhitungan OEE yaitu ketersediaan (availability), kinerja (performance), dan kualitas (quality). Rata-rata pencapaian nilai OEE di PT XYZ sebesar 50,11%, pencapaian nilai OEE ini masih dibawah standar perusahaan dunia yaitu 85%. Masalah utama yang menyebabkan rendahnya nilai OEE adalah tingginya waktu rehat selama produksi yang berupa minor stoppages. Metode Analitycal Hierarchy Process (AHP) digunakan untuk menemukan prioritas kriteria dan alternatif terbaik untuk menurunkan minor stoppage. Strategi yang dihasilkan dengan AHP untuk menurunkan minor stoppages sebagai upaya peningkatan OEE adalah melatih operator dalam menangani kerusakan, sehingga permasalahan mesin dapat cepat terselesaikan dengan bobot paling tinggi yaitu 0.331.

Judul: Morfologi dan filogeografi of Clavularia inflata Schenk, 1896 Schenk, 1896 (Karang Lunak: Stolonifera) in daerah pesisir Indonesian
Abstrak: The Coral Triangle is recognized as the center of the world’s marine biodiversity, with species richness declining gradually from this region to the east across the Pacific Ocean and west across Indian Ocean. This region covers many countries, such as Indonesia, Malaysia, Philippines, Brunei, East Timor (Timor Leste), Papua New Guinea, and Solomon Islands. There are around 96 genera and 23 families of soft coral in the Indo-Pacific. In Indonesia around 219 species, 28 genera, and 4 families of soft corals have been recorded. Clavularia is spread widely throughout the Indian and Pacific Ocean, stretching from the Red Sea and East Africa across the Indo-Pacific, reaching as far east as Micronesia. Clavularia is stoloniforous zooxanthellae soft coral, each one of the polyps is connected to the base. Polyps are pink to brownish gray and about 30 mm in diameter. Stolons are brown to dark red, and are often covered with algae or sponges. Genetic connectivity is the key of conservation because it plays important roles in maintaining populations and the potential for restoring damage to the marine environment. The connectivity patterns of sessile animals are affected by reproduction and larval spread. The stage of pelagic larvae is the initial stage of life for recruitment, so that it can maintain its population from extinction. Besides, the pattern of genetic connectivity can help in designing management plans for marine protected areas, which in turn can help to preserve biodiversity. Genetic connectivity between coral reefs is often overlooked when designing an area, but it is very important to ensure the continuity of populations or protection of biodiversity. This study aimed to confirm the identity of 25 colonies collected from 13 Indonesian coral reef location putatively identified as Clavularia inflata using molecular tools, and to describe them morphologically to verify defining characteristics and describe their morphological plasticity. Specimens were morphologically described based on their sclerite characteristics and compared between sites. All specimens were confirmed as Clavularia inflata by molecular identification using mitochondrial DNA with the mtMuts gene. Sclerite observations were divided into four parts for each colony, namely pinnules (finger-like extensions along the tentacless sides), crowns (tentacles covering the upper side of polyps, located between tentacles and calyx), calyx (the middle part of polyps), and stolons (branching between polyps). The form of sclerites found in Clavularia inflata comprised various forms such as rods, fingers, sticks, and brackets. The shortest size sclerites were found in the pinnule. These sclerites had a variety of sclerites such as grains with various geometric shapes such as platelet or finger biscuit shape. In the crown, the form of sclerites found was spindle-shaped sclerites (oval shaped with a shaft in the middle) with a curved shape. The middle part of the polyp (the calyx) is mostly covered by rod-shaped sclerites. Morphometric measurements of Clavularia inflata showed specimens from Kepulauan Seribu, Jakarta had the largest pinnule, calyx, and stolon compared to other locations. The maximum mean length of pinnule, calyx, and stolon were 145.1±19.27 µm, 1605.6±30.58 µm, and 749.5±52.8 µm, respectively. The maximum mean length of crown was 672,6±39.58 µm, found in Maluku
