Judul: Peranan sub sektor perkebunan rakyat dalam pembangunan wilayah Kabupaten Deli Serdang Propinsi Sumatera Utara
Abstrak: Pembangunan pertanian yang mencakup tanaman perkebunan, di samping bertujuan untuk meningkatkan hasil dan mutu produksi, meningkatkan pendapatan dan taraf hidup petani, juga ditujukan untuk memperluas kesempatan kerja dan kesempatan berusaha, menunjang sektor industri serta meningkatkan ekspor.

Judul: Kesempatan kerja, pendapatn petani dan distribusi pendapatan : Studi perbandingan antara desa binaan dengan desa non binaan PT. Tehnusamba Indah, Kabupaten Garut, Jawa Barat
Abstrak: Peranan sub sektor perkebunan dalam sektor pertanian sebagai bagian integral dari sistem pembangunan nasional dalam periode Pembangunan Jangka Panjang Tahap Kedua (PJPT II) diperkirakan akan semakin penting dan strategis sebagai akibat semakin menyusutnya sumber daya dan dana pembangunan nasional dari migas yang selama ini menjadi tumpuan. Teh sebagai komoditi andalan perkebunan yang cukup penting dalam perekonomian nasional perlu mendapat perhatian karena mampu menjadi sumber devisa yang mantap dan menjadi sumber mata pencaharian masyarakat banyak di- samping dapat manjaga kelestarian sumberdaya alam. Perkebunan teh rakyat sebagai bagian terbesar yaitu 39.6 persen dari total perkebunan teh nasional yang me- nyangkut hajat hidup orang banyak perlu diperbaiki sesuai azas Trilogi Pembangunan khususnya aspek pemerataan. Per- hatian tersebut dapat dituangkan melalui pengembangan industri pengolah teh rakyat. Pengembangan agroindustri teh rakyat dilakukan karena mempunyai kaitan (linkage) yang kuat dengan perkebunan teh rakyat dalam bentuk sumber input atau output yang digunakan, sekaligus untuk mengantisipasi berdampak negati dari transformasi struktural yang sedang terjadi...

Judul: Model’s Dynamics for Lymphocytes Recovery on the HIV presence with Protease Inhibitor Therapy.
Abstrak: HIV is a member of retrovirus that especially attacks lymphocytes or white blood cells, known as CD4+ T cells. New T cells created from sources within the body such as the thymus and by proliferation of existing T cells. In this paper, influence of protease inhibitor therapy in HIV dynamics will be analyzed. The influence can be categoried in three models, which are model HIV without drug therapy, model HIV with protease inhibitor and model T cell recovery. In the models, three parameters which are uninfected cells population, infected cells population and virus population are studied. From HIV without drug therapy model it is obtained two types fixed point which are uninfected fixed point and infected fixed point. The stability of fixed point depends on basic reproduction number which is influenceed by the total number of virus produced by a cell during its lifetime. From HIV with protease inhibitor therapy model it is obtained two type fixed points. The stability of fixed point depends on basic reproduction number. Other than influenceed by the total number of virus produced by a cell during its lifetime, basic reproduction number of this model also affected by the effectiveness of a protease inhibitor. Basic reproduction number of this model is smaller than that of model HIV without drug therapy. In the model T cell recovery, new T cells created only from sources within the body, and T cells can be invulnerable to HIV infection after the therapy. From the model it is obtained only one fixed point that is uninfected fixed point. The stability of fixed point depends on basic reproduction number. The total number of virus produced by a cell during its lifetime and the effectiveness of a protease inhibitor determine the basic reproduction number. Basic reproduction number of this model is smallest than that of other models.
