Judul: Value Chain Model of Anchovy (Stolephorus commersonnii) Industry with Sustainability Business in Sumenep Regency, Madura, East Java
Abstrak: Permasalahan perikanan di Kabupaten Sumenep sangat kompleks, dimulai dari penangkapan hingga pemasaran. Masalah utama meliputi penurunan produktivitas, kurangnya fokus pemerintah pada pengelolaan rantai pasok ikan teri nasi, dan keterbatasan informasi relevan. Penelitian bertujuan menciptakan model rantai pasok yang efisien, bisnis berkelanjutan, dan menguntungkan semua pelaku usaha, termasuk nelayan dan pengrajin teri nasi. Pendekatan sistem mencakup analisis kebutuhan, formulasi masalah, dan rekayasa model awal dengan diagram causal loop dan input-output. Hasil menunjukkan rantai pasok ikan teri nasi di Sumenep melibatkan tujuh pelaku utama: nelayan, pengepul, pemasok besar, industri ekspor, perusahaan induk, pengolah teri nasi krispi, dan konsumen akhir. Selanjutnya, ada tiga aliran utama: barang (hulu ke hilir), uang (hilir ke hulu dan hulu ke hilir), dan informasi (hulu ke hilir dan hilir ke hulu). Analisis nilai tambah pengolahan teri nasi di Sumenep rendah, rata-rata kurang dari 50%. Model menunjukkan target minimum produksi dan keuntungan untuk setiap pelaku usaha, termasuk nelayan pemilik kapal (1.538 kg, Rp33.846.154), pengepul (3.304 kg, Rp111.000.000), pemasok besar (314 kg, Rp35.000.000), perusahaan chirimen (1.094 kg, Rp218.776.551), dan pengolah teri nasi krispi (2 kg, Rp275.735), yang mana tiap mata rantai membutuhkan volume sekian dengan jumlah keuntungan tersebut untuk mendapatkan target minimum produksi yang ideal.

Judul: Analisis Bioekonomi Pengelolaan dan Pemanfaatan Sumberdaya Ikan Teri (Stolephorus sp.) di Perairan Kabupaten Asahan, Provinsi Sumatera Utara
Abstrak: Anchovy is one of important pelagic species produced in Asahan Regency. Anchovy production not only to supply local needs, but also it has been exported to neighboring countries. Based on the analysis of the declining of achovy production showed that there is problem in resource management. The objectives of this research were to study proper anchovy resource management in the Asahan sea. Analytical approaches were used bioeconomic and variance analyses. Bioeconomic analysis using Gordon-Schaefer model approach obtained the actual catchment condition (h) is 725.94 tons/year, effort (E) 947.22 trips/year and the economic rent of Rp 12,648,510,194/year. Catch of MSY level (h) is 1,200.92 tons/year, effort (E) 834.96 trips/year and the economic rent of Rp 22,951,655,440/year. Catch of MEY level (h) is 1,198.41 tons/year, effort (E) 796.75 trips/year and economic rent of Rp 23,004,560,220/year. Current exploitation rate has exceeded sustainable levels of optimal exploitation both in terms of MSY or MEY which lead to overfishing. Based on the estimation of degradation and depreciation rate, the anchovy resource in the Asahan sea has not been degradated and depreciated. This is indicated by the value of degradation and depreciation rate coefficient are 0.27774 and 0.28790. The factors that significantly correlated with fishers perception to anchovy resource are fishing gears, government programs, and the environment are the education levels, fishing experience, and the participation in fisher's organizations. Anchovy resource management can be directed toward MEY conditions to obtain the maximum benefit, but this policy has an impact on the reduction of labor. In order to absorb the larger employment and the sustainability of resource, the resource management policy is directed toward MSY level by reducing fishing gears as much 112,26 units anchovy purse seine from the current level of exploitation. This policy must be supported by clear rule/ regulations and continuous monitored by all parties.

Judul: Aktivitas Beberapa Antimikotik terhadap Microsporum gypseum sebagai Penyebab Dermatofitosis pada Kuda
Abstrak: Dermatophytosis is a superficial cutaneous fungal infection that attacks the keratin layer of the skin caused by a group of fungi known as dermatophytes. Microsporum gypseum is a geophilic dermatophyte that suspected to cause this infection in horses. In this research, isolation and identification of sample from the horse that was suspected to be infected with dermatophytosis caused by M.gypseum was done. As an effort to treat dermatophytosis, antimycotics are widely used. The aim of this study is to be able to diagnose accurately the cause of dermatophytosis in horses and the agent that causes it.The procedure of this research included rapid isolation and identification, using KOH 10%, isolation onto DSA media and identification using Riddle’s slide culture method. The antimycotic test was done using disk diffusion assay method and the antimycotics used in the test were ketoconazole, amphotericine, voriconazole, fluconazole, griseofulvin, and miconazole, producing inhibition zones with diameters 0 mm, 0 mm, 8.5 mm, 0 mm, 17.25 mm, and 12.25 mm respectively at the end of the test. This study revealed that griseofulvin has the best antimycotic activity against M.gypseum and can be used as the drug of choice for the treatment of dermatophytosis caused by the fungi.
