Judul: Pemodelan Kuantitatif Penanganan Risiko Pasokan dan Mutu pada Rantai Pasok Tanaman Hias Mini
Abstrak: Mini floricultures are agricultural commodities that have high economic value, especially if that are produced in unique forms such as parcels, souvenirs and others. This plants can be damaged or decrease in quality since its products enjoyed by consumers in the form of live or fresh products. This thesis contains quantitative models for mitigation of supply and quality risk of mini floricultures which can be used to solve the problems of risk in agro commodities. Stages in this study were identification and analysis of risks of supply and quality of mini floricultures using fuzzy failure mode and effect analysis (fuzzy FMEA) to acquire a risk profile, and then to design models for risk mitigation of supply and quality in mini floricultures supply chain. Primary members of the supply chain consists of Ciapus and Lembang farmers as floriculture’s suppliers, Rumah Teduh Green Souvenir as an industry, and customers in general are event organizers, hotels, offices, public, individual and so on. Products of Rumah Teduh are economical and exclusive souvenirs, parcels, pot scapings dan dishplants. Secondary members of the supply chain are the other farmers that have specific floricultures (that are not owned by Lembang and Ciapus farmers) as well as suppliers of packaging material such as mica, pot (plastic and ceramic), baskets, the sand for accessories, zeolit stones dan other materials. Handling product quality of mini plants conducted from handling quality of plants at the farmer up the handling quality of processes and products at the industry level. Handling quality of plants at farmers aim to produce plants with desired standards and criteria by the industry which are plants have attractive shapes and colors, can display a mini form with about 10 cm tall plants, plants look lush, plant growth is relatively slow, easy maintenance, relatively resistant in conditions of Jakarta nature, pest-resistant, and easy packaging. The results showed that the risks priorities to be addressed in Ciapus farmer were climate/weather disruption, damage to and deterioration of seeds / plants at the reception, the limitations of seedling, floricultures and cultivation facilities, lack of capital, dan shortage of stocks and supplies of mini plants, whereas in Lembang farmer, the risks priorities to be addressed were the lack of capital, attack of pests and plant diseases, damage and deterioration during seed breeding, and climate/weather disruption. The supply and quality risks in the industry level priorities to be addressed were the change in the number of requests, increasing the number of orders unexpectedly, the high price of packaging, overlapping processes for different customers, shortage of supplies of floricultures and auxiliary materials, and manpower shortages. Quantitative models for mitigation of supply and quality risk of mini floriculture were built to minimize risk by maximizing the fulfillment of product demand and minimizing production costs, so as to maximize profits. Efforts to meet the demand of the products were done by ensuring the availability of supplies of raw and auxiliary materials, ie by minimizing production costs and optimizing existing resources, so that the risks of the supply and quality of the products can be handled well.

Judul: Pengelolaan Risiko Produksi Buncis Mini pada PD Pacet Segar, Kabupaten Cianjur
Abstrak: One of the important commodities of the horticulture sub-sector and has the opportunity to be developed includes vegetables. Mini bean, one type of vegetables, tends to increase its total production annually. Mini bean cultivation cannot be separated from production risks. PD Pacet Segar is one of the companies cultivating mini bean in Cianjur. This study is aiming at identifying risk sources of mini bean production, analyzing the possibility of risk occurrence and impact of risk source of mini bean production towards its revenue, as well as analyzing appropriate alternative strategies to address the mini bean production risks. The data analysis method used descriptive analysis and risk analysis. This study used primary data and secondary data, all of data is qualitative and quantitative data. Based on the field observations, the sources of risks in mini bean production included weather changes, seed quality, diseases, and pest attacks. Weather changes are a source of risk that may occur and have the greatest impact. The results of the risk mapping results indicated that there were two kinds of treatment strategies including preventive and mitigation strategies

Judul: Sintesis Superkonduktor YBCO dengan Metode Evaporasi dan Karakterisasinya
Abstrak: Telah berhasil dibuat pelet superkonduktor YBCO-123 dengan metode evaporasi dengan menghasilkan Tc = 100 K. Sintesis dilakukan dengan mencampur garam-garam nitrat Y(NO3)2, Ba(NO3), Cu(NO3)2 di dalam pelarut H2O pada suhu 150 oC. Setelah melalui proses pirolisis pada 350 oC selama 1 jam, prekursor dikalsinasi pada 900 oC selama 4 jam kemudian serbuk dikompaksi dengan tekanan hidrolik 5 ton untuk membentuk pelet dengan diameter 1,5 cm dan tebal 0,24 mm. Sintering dilakukan pada suhu 940 oC selama 20 jam. Efek meissner menunjukkan fenomena levitasi pada temperatur sekitar 80 K. Hal ini menunjukkan fasa superkonduktor telah terbentuk. Data XRD memberi mengkonfirmasi bahwa fasa kristal 123 telah terbentuk. Nilai konduktivitas didapat dari hasil pengukuran dengan LCR pada temperatur 300 K sebesar 4 x 10-5 S/cm. Pada penurunan temperatur dari 100 K ke 80 K terjadi kenaikan nilai konduktansi yang tajam dari 4.2 x 10-4 S/cm ke nilai 1.309 x 10-1 S/cm.
