Judul: Adaptive Decision Support System For Potato Commodity Supply Chain Risk Management (Case Study: Wonosobo District)
Abstrak: Kentang merupakan salah satu komoditas unggulan di Kabupaten Wonosobo yang berpotensi untuk dikembangkan diiringi oleh pengelolaan risiko yang tepat. Penelitian ini bertujuan menganalisis kinerja rantai pasok, mengidentifikasi dan menyusun strategi mitigasi risiko rantai pasok, serta merancang model penunjang keputusan manajemen risiko rantai pasok kentang. Pengukuran kinerja rantai pasok kentang dengan pendekatan Supply Chain Operation Reference (SCOR) dan Analytical Hierarchy Process (AHP). Hasil tersebut menunjukkan bahwa tingkat kinerja untuk petani (91.93%), pengepul (93.05%), dan industri UKM (89.15%) sangat baik. Identifikasi sumber risiko dengan House of Risk (HOR) 1 dan pendekatan fuzzy Failure Mode Effect Analysis (FMEA). Hasil identifikasi didapatkan 7 sumber risiko prioritas pada petani, 5 sumber risiko prioritas pada pengepul, dan 5 sumber risiko prioritas pada industri UKM. Upaya mitigasi risiko diidentifikasi dengan pendekatan HOR 2 dan Fuzzy Inference System (FIS). Hasil menunjukkan terdapat 7 prioritas aksi mitigasi pada petani, 4 prioritas aksi mitigasi pada pengepul, dan 5 prioritas aksi mitigasi pada industri UKM. Penyusunan strategi mitigasi risiko dengan fuzzy AHP menunjukkan 3 aksi mitigasi terpenting yaitu 3 aksi mitigasi pada petani. Model sistem penunjang pengambilan keputusan merupakan pemodelan berorientasi objek yang dapat membantu pengguna dalam melakukan evaluasi kinerja dan pengambilan keputusan dalam manajemen risiko rantai pasok yang lebih efisien., Potatoes are one of the leading commodities in Wonosobo Regency which have the potential to be developed with good risk management. This study aims to analyze supply chain performance, identify and develop supply chain risk mitigation strategies, and design a decision support model for the management of potato supply chain risk. Measuring the performance of the potato supply chain using the Supply Chain Operation Reference (SCOR) and Analytical Hierarchy Process (AHP) approach. These results indicate that the level of performance for farmers (91.93%), collectors (93.05%), and the industry (89.15%) is very good. The risk agent identification was done by using House of Risk (HOR) and fuzzy Failure Mode Effect Analysis (FMEA) approach. It found 7 priority risk agents in farmer’s level, 5 risk agents in collector’s level, and 5 risk agent in industries level. HOR 2 and Fuzzy Inference System (FIS) approaches were used in identifying risk mitigation. The result showed there were 7 preventive acton priorities to the farmers, 4 priority mitigation action on the collectors, and 5 priority mitigation action on the industry. The formulation of risk mitigation strategies using fuzzy AHP shows the 3 most important mitigation actions that can be implemented. The decision support system model is an object-oriented modeling that can assist users in evaluating performance and making decisions in a more efficient supply chain risk management.

Judul: Pemodelan sistem pendukung pengambilan keputusan cerdas manajemen risiko rantai pasok produk/ komoditi jagung, Intelligent decision support system modeling for corn supply chain risk management
Abstrak: Manajemen rantai pasokan produk pertanian umumnya berbeda dengan manajemen rantai pasokan produk manufaktur, karena produk pertanian mudah rusak, ketersediaannya bergantung pada musim, bentuk dan ukurannya yang bervariasi, dan juga kamba sehingga sulit untuk ditangani. Kompleksitas yang tinggi dari jaringan rantai pasok dan karakteristik produk menjadikan manajemen rantai pasokan produk pertanian lebih rentan terhadap munculnya risiko kerugian. Untuk memenuhi kebutuhan jagung nasional pada industri pakan yang membutuhkan kelangsungan penyediaan bahan baku dengan kuantitas tertentu sepanjang tahun, dalam kondisi produksi jagung nasional yang berfluktuasi, maka diperlukan perencanaan pasokan dan metode penyimpanan untuk menghindari risiko pasokan jagung berupa krisis kekurangan pangan atau kenaikan harga pakan. Ketidaksesuaian pola penjadwalan tanam akan menyebabkan penurunan produksi dan persediaan yang tidak konsisten, dan kemudian dapat menyebabkan penumpukan produk pada saat panen raya dan kelangkaan produk pada saat yang lain yang menimbulkan risiko fluktuasi harga. Risiko itu tidak hanya diderita oleh produsen, tetapi juga akan mempengaruhi pencapaian organisasi lain yang terhubung dalam jaringan rantai pasok. Oleh karena itu, perlu adanya manajemen pola penjadwalan yang optimal untuk dapat mengatasi kemungkinan risiko tersebut.

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
