Judul: Root endophytic fungi of tomato and their role as biocontrol agents of root-knot nematodes Meloidogyne incognita (Kofoid and white) Chitwood and growth promotion in tomato plants (Lycopersicon esculentum Mill):
Abstrak: Nematoda puru akar, (Meloidogyme incognita) adalah salah satu OPT utama tomat (Lycopersicon esculentum Mill) di seluruh dunia. Tujuan penelitian ini adalah untuk (1) mengeksploitasi cendawan endofit (2) melihat pengaruh cendawan endofit terhadap nematoda puru akar (Meloidogyne incognita) serta pemacu pertumbuahan pada tanaman tomat, (3) menginvestigasi mekanisme cendawan endofit menekan nematoda puru akar secara in-vitro.

Judul: Potential of Bacterial as Biocontrol Agent for Root-Knot Nematode Meloidogyne incognita and Growth Promoter of Tomato Plant
Abstrak: Meloidogyne incognita atau nematoda puru akar (NPA) adalah nematoda endoparasit akar tanaman. Penggunaan nematisida dinilai efektif, namun berbahaya bagi kesehatan manusia dan lingkungan. Bakteri memproduksi metabolit sekunder dan enzim litik yang bersifat nematisidal. Penelitian bertujuan mengisolasi dan menskrining bakteri yang berpotensi sebagai agen biokontrol M. incognita pada kondisi in vitro dan pemacu pertumbuhan tanaman. Tahapan penelitian meliputi isolasi bakteri, skrining in vitro sel bakteri, uji reaksi hipersensitivitas dan hemolisis, uji in vitro filtrat bakteri terpilih, uji pengaruh bakteri terpilih terhadap pertumbuhan tanaman tomat, serta karakterisasi dan identifikasi molekuler isolat terpilih. Sebanyak 44 isolat terdiri dari 11 bakteri endofit dan 33 bakteri rizosfer berhasil diisolasi serta 14 isolat diantaranya menyebabkan mortalitas J2 sebesar 55,3% hingga 74,2% dan penetasan telur sebesar 6,5% hingga 12,1%. Uji hipersensitivitas dan hemolisis memperoleh dua isolat rizosfer, Z2.1R dan Z1.3R, yang tidak berpotensi patogenik bagi tanaman dan manusia. Filtrat Z2.1R dan Z1.3R yang disaring menyebabkan mortalitas J2 berturut-turut sebesar 70,1% dan 22,2% serta penetasan telur berturut-turut sebesar 10,8% dan 12,8%. Kedua isolat mampu meningkatkan pertumbuhan tinggi tanaman tomat di rumah kaca berturut-turut sebesar 38,2% dan 42,0% dibandingkan dengan kedua kontrol Temik 5G dan akuades steril. Kedua isolat memiliki karakter koloni bundar, tepian rata, elevasi datar, dan termasuk dalam bakteri Gram positif. Identifikasi molekuler menunjukkan bahwa Z2.1R memiliki kemiripan 99,7% dengan Lysinibacillus xylanilyticus dan Z1.3R memiliki kemiripan 95,5% dengan L. sphaericus. Kedua isolat berpotensi menjadi agen biokontrol M. incognita dan memacu pertumbuhan tanaman sehingga perlu diuji lanjut kemampuannya dalam menekan gejala puru akar dan populasi NPA.

Judul: Analisis Optimisasi Persediaan Mata Uang Riyal untuk Musim Ibadah Haji (Studi Kasus di Bank Syariah Mandiri Cabang Bekasi)
Abstrak: SAR or Saudi Arabian Real is the currency of Saudi Arabia is widely used to meet the requirements during the pilgrimage. In 2011, the number of Hajj is dominated fleet departure from Jakarta-Bekasi embarkation fleet as much as 85 groups or 37,740 worshipers. This has resulted in high demand for SAR in several local banks to provide more SAR during the pilgrimage season, one of which is a Bank Syariah Mandiri Bekasi Branch has provided SAR more than other Bank Syariah Mandiri Branch, in the amount of 210,000 SAR. The amount of inventory that has been prepared BSM Bekasi branch sometimes not in line with the level of demand for SAR because of the uncertain state of demand. This condition, triggering BSM Bekasi Branch excess inventory, so that the necessary proper inventory management. This study aims to (1) Studying the patterns of demand and supply SAR for the Hajj season, (2) Selecting inventory models SAR for the Hajj season, (3) Calculating the optimal inventory levels SAR. The primary data used in this study were obtained through direct interviews with the BSM Bekasi Branch and the Ministry of Religious based list of questions directly. Secondary data obtained from historical data company, literature studies, articles or research related literature. Qualitative data analysis is done by analyzing the patterns of demand and supply patterns, as well as the BSM condition Bekasi Branch. Quantitative data analysis is done by calculating the optimum supply quantity of demand that has been forecast. Based on the pattern of inventory, ordering SAR does not occur every month because the supply is only focused on the pilgrimage season. Hajj month period can be determined based on the high demand SAR in a given month. Pattern of demand and supply patterns, forecasting can be done about the number of reservations by observing the pattern of demand SAR during the Hajj months to avoid excess or shortage of inventory. Forecasting demand of 158,682 SAR in the period from Hajj performed by using the moving average method. Judging from the conditions that existed at BSM Bekasi branch, where demand SAR during the Hajj season varies and can not be known with certainty, a two-day lead time, order frequency as needed, the inventory method that can be applied BSM Bekasi branch is continuous method probabilitic EOQ. Determination of optimum quantity obtained through iteration, that is equal to 101,244 SAR with reorder levels and inventory reserves amounted to 16,592 SAR and 11,302 SAR. The optimal conditions can anticipate the resulting excess inventory inefficiencies, as well as inventory shortages resulting in loss of customer trust, so that the Bekasi branch of Bank Syariah Mandiri to optimize profitability and create customer loyalty.
