Judul: Penjadwalan Karyawan Menggunakan Goal Programming: Studi Kasus di Divisi Contact Center PLN
Abstrak: Masalah penjadwalan karyawan merupakan masalah praktis yang muncul di suatu instansi. Selama ini penjadwalan kerja karyawan masih banyak yang dilakukan secara manual (metode konvensional), akibatnya penjadwalan membutuhkan waktu yang relatif lebih lama. Penjadwalan yang tidak tepat dapat menyebabkan karyawan kelelahan dan berdampak buruk pada pekerjaan. Hal tersebut juga dapat menimbulkan kerugian bagi instansi. Faktor-faktor yang terlibat dalam masalah penjadwalan ini antara lain, keterbatasan banyaknya karyawan, pembagian shift, hari libur, dan sebagainya. Oleh karena itu, penjadwalan kerja secara efisien menjadi sangatlah penting. Permasalahan penjadwalan dalam karya ilmiah ini dapat dimodelkan sebagai masalah nonpreemptive goal programming. Fungsi objektifnya yaitu meminimumkan total kekurangan dan/atau kelebihan (deviasi) terhadap sasaran yang ingin dicapai. Sasaran tersebut salah satunya berupa keinginan karyawan, misalnya karyawan mendapat sedikitnya 2 hari libur dalam 8 hari. Dalam karya ilmiah ini diperoleh penjadwalan karyawan yang memenuhi semua aturan perusahaan dan sedapat mungkin memenuhi keinginan semua karyawan.

Judul: Penjadwalan Pegawai Apartemen Menggunakan Goal  Programming
Abstrak: Masalah penjadwalan pegawai sering ditemukan pada suatu instansi. Penjadwalan perlu memperhatikan beberapa faktor di antaranya adalah jumlah pegawai, kebutuhan pegawai pada tiap sesi, hari libur pegawai, dan lainnya. Dalam penelitian ini dibahas masalah penjadwalan pegawai di Apartemen Cibubur Village dan diselesaikan menggunakan goal programming. Penelitian ini memiliki dua skenario; Skenario 1 menggunakan data yang sudah ada dan Skenario 2 dengan menambahkan banyaknya pegawai dengan memperhatikan keperluan manajemen. Dari dua skenario diperoleh penjadwalan pegawai yang memenuhi pegawai chief security yang sudah mendapatkan Shift Malam-Pagi tidak mendapatkan Shift Pagi-Malam esoknya, setiap pegawai dari tim yang sama mendapat hari libur yg sama, dan pegawai pada setiap tim bekerja maksimal 6 hari berturut-turut.

Judul: Merremia dennstedt ex endlicher (Convolvulaceae) in Sumatra.
Abstrak: Merremia is a small genus in the family Convolvulaceae. Merremia is a perennial or annual herb or woody liana with stems creeping or twinning on trees or rocks, put out milky white sap when injured and some species with tubers. Merremia is often confused with genus Ipomoea, due to they have resemblance in funnel shaped or campanulate corolla and straight anther. Phenetically, some members of Merremia have yellow flower whereas Ipomoea has white, purple or purplish white. Merremia is also confused with Operculina due both have non-spinulose pollen and dehiscent capsule. Nevertheless, Operculina characterized by circumciselli capsule and Merremia characterized by valve capsule. The important character in Merremia is the spread of the hairs on corolla that can be easily observed at the mature flower bud. The genus Merremia is found in the tropical regions of both hemispheres. Merremia wildly distributed throughout the tropical regions of Asia, Africa, Australia, North and South America and approximately there were 80 species of Merremia in the world. A Total of 175 sheets (164 collection numbers) which are deposited in Herbarium Bogoriense, 97 sheets (95 collection numbers) which are deposited Andalas University Herbarium (ANDA) and 9 sheets (4 collection numbers) which are deposited in BIOTROP Herbarium (BIOT) were studied. It composed of all specimens of Merremia in Sumatra. Additional specimens were collected by the author 28 sheets (15 collection numbers) from North Sumatra, West Sumatra and Lampung, which are stored in BO and BIOT. The digital data that consist of type specimens and distributions of species from JSTOR Plant Science and Convolvulaceae Unlimited were also used here. All the hebarium specimens were studied based on their morphological characters following de Vogel (1987) and Rifai (1976). The terminology of morphological characters followed Lawrence (1955), Veldkamp (1987), Harris and Harris (1994), Hickey and King (2005) and Stearn (1983). Information on the habitat, ecology, distribution, vernacular names and uses were noted from the specimens label and literatures. Taxonomic studies in Sumatra were conducted. There are eight species, one subspecies, one varietas and two forma from nine previously species (M. cissoides, M. dissecta, M. emarginata, M. hirta, M. peltata, M. quinquefolia, M. tridentata, M. tuberosa and M. vitifolia), two subspecies (M. umbellata ssp. orientalis and M. tridentata ssp. hastata), one varietas (M. boisiana var. sumatrana) and two forma (M. hederacea f. pubescens and M. hederacea f. barbata) can be recognized. One species (M. tridentata) and subspecies (M. tridentata ssp. hastata) are excluded because they have been proposed to different new taxa Xenostegia by Austin and Staples. The existence of M. emarginata was noted as new record in Sumatra and M. cissoides was noted as new record in Indonesia. A phylogenetic analysis using PAUP*4.Ob10 was undertaken based on morphological characters, using Evolvulus nummularius and Porana volubis as the out group. The phylogenetic analysis used 35 morphological characters was resulted consistency index (CI) = 0.60, homoplasy index (HI) = 0.40, retention index (RI) = 0.56 and Rescaled consistency index (RC) = 0.34. Phylogenetic tree used morphological characters divided taxa into two groups. The separation support M. boisiana var. sumatrana, M. cissoides, M.
