Tanaman kopi merupakan salah satu jenis tanaman perkebunan yang memiliki nilai ekonomis tinggi. Kopi terdiri dari beberapa jenis diantaranya  Arabica, Robusta,  Liberika dan Excelsa. Sesuai dengan Iklim, tanaman kopi yang dikembangkan di Indonesia adalah arabika dan robusta. Salah satu lokasi pengembangan kopi arabika di Indonesia adalah di Kabupaten  Dogiyai. Produksi kopi di dogiyai, sudah dilakukan hingga menjadi kopi bubuk, dan  siap dijual. Kualitas kopi arabika bubuk dapat ditentukan dengan sifat fisik dan kimia yang dimiliki. Sifat fisik diperoleh dengan melakukan uji organoleptik, sedangkan sifat kimia diperoleh dengan melakukan analisis proksimat. Penelitian ini bertujuan untuk menganalisis sifat kimia dari kopi arabika bubuk asal kabupaten Dogiyai. Pengambilan Sampel dilakukan di kampung Bomomani dan Moanemani.  Sampel kemudian dianalisis di Laboratorium Analisis dan Kalibrasi Balai Besar lndustri Agro, Bogor. Komponen kimia yang dianalisis adalah kadar air (2,32%-3,64%), kadar abu(4,10% – 4,54%), protein(12,6% – 13,7%), lemak (11,5% - 14,7%), karbohidrat (65 % - 68,3%), sari kopi(22,2% - 25,6%), dan kadar kafein (1,17% - 1,32%). Semua komponen kimia kopi tersebut telah memenuhi Standar Nasional Indonesia.

The objective of this study is to know the ripeness level of small chilli and the right temperature during storage as far as the quality of small chilli can to defend until marketing.

Papua is rich in biodiversity. The indigenous Papuans utilize most of endemic plants as food, board and medicines. One of the plants used as medicine is Laportea, sp, that locally known as Daun Gatal. The plant however, has not been developed commercially; this might due to lack of scientific providence of medicine content in this plant. The aims of this research is to (1) explore the types of Laportea growing in Papua, (2) conduct bio molecular character, which observes phylogeny relationship or genetic morphology in order to obtain data on the number of species found in Manokwari and Nabire. Bio molecular analysis is performed by PCR. Genetic analysis in this study was conducted through several phases, as follow: (a) Isolation of genomic total, (b) amplification of genes that encoded Rbcl, (c) sequencing the nucleotide sequence of the

<em>Penelitian ini bertujuan untuk mengidentifikasikan sistem budidaya dan pemanfaatan sayur hitam (Rungia Klossii ) oleh suku Ekari di Kabupaten Dogiyai serta memberikan informasi nutrisi yang terdapat pada sayur hitam (Rungia Klossii). Metode yang digunakan adalah metode deskriptif dengan tehnik observasi langsung pada tanaman sayur hitam di lapang dengan mengamati sistem budidaya dan kandungan nutrisi tanaman. Prosedur analisa menggunakan Gravimetri dan Spektrofotometri Serapan Atom. Analisis dilakukan di Laboratorium Kimia, Fakultas MIPA, Universitas Papua bulan April 2016.  Peubah yang diamati berdasarkan metode tersebut  meliputi identifikasi sistem budidaya dan kandungan nutrisi pada tanaman yang dianalisis pada bagian daun.   Sistem pertanian yang diterapkan oleh masyarakat dalam menanam sayur hitam (Rungia klosii) adalah sistem pertanian campuran. Berdasarkan hasil analisis kandungan nutrisi Rungia klossii meliputi kadar air, kadar minyak lemak, kadar besi, kadar mangan, kadar kalsium, dan kadar magnesium. Kandungan magnesium pada tanaman Rungia klossii adalah yang tertinggi yaitu 272, 0892 mg/L.</em>

One of the arabica coffee producing areas in Indonesia is in the Dogiyai regency. Several communities in the regency, especially the district Kamuu have coffee plantations that are managed since the 1960s. Farmers (producers) sell coffee beans to the traders. Arabica coffee beans are made into powder and marketed. In the process of marketing, business administration analysis is needed. It is conducted to know the channels and business administration functions, margins, business administration costs, profits, efficiency, as well as fees received by farmers (producers). Data was collected using the method of observation and interviews, and data collected in the form of primary and secondary data. Data is processed using tabulation. The Arabica coffee trading channel in Kamuu district is a one-level channel consisting of consumer-producer-trader traders. The trade system function at the farmer (producer) level is the financing function, while at the level of the trader, it consists of the financing function, physical function, and facility function. The Arabica coffee marketing margin is Rp. 200,000 / kg. The average cost of the trading system is Rp.31,250 / kg with a profit of Rp.168,750 / kg. Arabica coffee trading system in Kamuu district is already efficient with the fees received by farmers (producers) reached 50 percent.
