Abstrak: Manajemen persediaan berkaitan dengan kelancaran proses produksi dan kemungkinan terjadinya kehilangan penjualan. Jika persediaan berlebihan maka perusahaan akan mengeluarkan biaya lebih untuk biaya penyimpanan dan biaya pemesanan. Akan tetapi, jika terjadi kekurangan persediaan maka dapat menghambat kelancaran proses produksi. Penelitian ini bertujuan untuk menganalisis pengendalian persediaan yang efisien guna meminimalkan biaya persediaan. Metode yang digunakan yaitu peramalan permintaan dengan multiplicative seasonal model untuk mengetahui permintaan di masa yang akan datang, serta metode EOQ dan POQ untuk pengendalian persediaan bahan baku dengan bantuan Software Microsoft Excel dan POM-QM for Windows. Hasil perbandingan pengendalian persediaan menunjukkan metode EOQ atau POQ dapat menjadi alternatif pengendalian persediaan perusahaan. Bahan baku glucose menghasilkan penghematan biaya persediaan sebesar 50.91% atau Rp11,622,406. Bahan baku oil menghasilkan penghematan biaya persediaan sebesar 23.79% atau Rp4,538,990. Sedangkan bahan baku powder menghasilkan penghematan biaya persediaan sebesar 37.81% atau Rp13,558,947.

Abstrak: One of the constraints in the cultivation of giant gouramy is the lack of fry availability, necessitating the development of fry production engineering technology to address these issues. Engineering technology of fry production through the surrogate broodstock generated by testicular cells transplantation technique has been developed in salmonid. Testicular cells transplantation technology requires a suitable recipient that can accept and support the development of spermatogonia donor cell. This study examined the potential of Nile tilapia as a recipient for donor giant gouramy cells by observing its colonization in the gonads of Nile tilapia. Fish donor of 598,82 grams body weight with Gonado Somatic Index (GSI) of 0,013% and spermatogonial cells percentage of 28,22% was used. Testicular cells in amount of 20.000 cells/0,5 μl PBS were injected into peritoneal cavity of 4-day-old tilapia larvae. The success of transplantation and donor cell colonization were analyzed using PCR method with DNA template that have been extracted from tilapia larvae of 1 day post injection and the gonad of 2 months old fish. PCR was performed using a set of specific primer for the giant gouramy growth hormone gene and tilapia β-actin as an internal control of DNA loading. PCR results showed that the transplanted tilapia has a DNA band in the same size with giant gouramy, and not in untransplanted control. The success rate of transplantation in larvae was 100% (5/5) and the percentage of individual recipients containing donor cells in their gonad was 60% (3/5). This indicates that donor cells from giant gouramy was successfully injected and can be colonized in the gonads of Nile tilapia, so the Nile tilapia potentially be used as recipient for giant gouramy testicular cells transplantation. Further analysis needs to be conducted to observe the ability of spermatogonial cells develop into sperm and eggs in the gonad of tilapia recipient.
