Kopi merupakan salah satu komoditas perkebunan yang memiliki nilai ekonomi yang cukup tinggi. Kegiatan magang bertujuan mempelajari teknik budidaya tanaman dan pengelolaan perkebunan kopi, mempelajari dan menganalisis permasalahan yang dihadapi di lapangan mengenai pengelolaan pemangkasan serta solusi mengatasinya. Pemangkasan bertujuan agar pohon tetap rendah sehingga mudah perawatannya, dan membentuk cabang-cabang produksi yang baru. Kegiatan magang dilaksanakan di Kebun Blawan, Bondowoso, Jawa Timur, mulai bulan Februari sampai dengan Juni 2014. Pengumpulan data primer diperoleh melalui pengamatan dan praktik kerja secara langsung meliputi kegiatan pemeliharaan tanaman yaitu pemangkasan lepas panen (pengamatan cabang-cabang tanaman, tinggi tanaman, jumlah tunas yang tumbuh), sedangkan data sekunder diperoleh melalui laporan manajemen perusahaan. Analisis data yang dilakukan secara deskriptif, rata-rata dan persentase. Pemangkasan yang dilakukan termasuk dalam kategori pemangkasan ringan. Tanaman kopi yang memiliki kondisi cabang yang merata dan seimbang sangat mempengaruhi hasil taksasi produksi. Banyak cabang harus dipangkas karena cabang-cabang yang sudah tua dan terserang penyakit. Setelah melakukan pemangkasan, tanaman menghasilkan tunas-tunas baru.

Forest cloves (Syzygium aromaticum (L.) Merr. & L. M. Perry.) are classified as wild and endemic clove to Maluku islands. So far, the studies on utilization of clove oil as an essential oil are still limited. This study aims to provide information on the physicochemical properties of clove oil from three clove accession groups in Maluku. Clove oil is obtained through the distillation of parts of the plant such as flowers bud, flower stalks, and leaves. The physicochemical components of clove oil in this study were compared to those of the standard type of cultivated clove oil, for there is no standard for forest clove oil. The results of the characterization of the physicochemical properties of clove oil revealed that the oils of the three clove accession groups met the standard of clove oil in several parameters, namely color (yellow to dark brown), specific gravity (0.9559-1,101 g ml−1), refractive index (1.5075-1.5467), β-caryophyllene (0.74-11.79%). However, they did not meet the standard of clove oil solubility in ethanol 70% (1:10) and total eugenol (20-28%). The clove accession groups had high oil content (in the distillation) from the flower bud section (1.33-3.00%), followed by the flower stalks (0.40-1.0%), and leaves (0.44-0.93%).

Forest clove (Zyzygium aromaticum) is a type of wild clove found in Moluccas. The increasing interest of farmers in cultivating this plant leads to complete their information of morpho-agronomical characteristics which could provide diversity reflecting morpho-agronomical their distribution areas. This study aimed to characterize the morpho-agronomical traits of Forest clove plants in Moluccas. By survey, Forest clove more than 15 year old tree totalling of 50 populations were observed their 54 morpho-agronomical characteristics in two areas (Ambon and Seram) from March to June 2018. Two aromatic cloves, namely Tuni and Zanzibar were used for comparative analysis. The results showed that Forest cloves had a similarity of 78% among the population and grouped into 3 groups with a morpho-agronomical variation of 22%. On the contrary, Forest cloves and comparators (Tuni and Zanzibar) had morpho-agronomical differences of 58%. Based on the main component analysis, there were 11 most influential characters of Forest cloves (leaf size index, leaf length, leaf width, leaf area, petiole length, flower length, diameter of flower tube, ripe flower weight, fruit length, fruit width, and fruit weight) which could be descriptors for this plant species.

Kegiatan yang dilaksanakan di Pelantaran Agro Estate (PAGE), Kota Waringin Timur, Center Borneo dimulai dari 14 Februari 2011 hingga 14 Juni 2011. Tujuan kegiatan ini adalah menganalisa pengelolaan panen pada perkebunan Kelapa Sawit. Pengelolaan panen Kelapa Sawit penting dalam upaya mencapai kuantitas dan kualitas minyak kelapa sawit yang tinggi. Data primer diperoleh dengan mengikuti keseluruhan kegiatan di perkebunan ini, pengamatan di lapangan, wawancara, dan diskusi langsung atau tidak langsung dengan staf. Data sekunder diperoleh dari laporan manajemen. Berdasarkan pengamatan selama kegiatan di PAGE dapat disimpulkan bahwa sudah memiliki pemahaman yang baik tentang kriteria buah masak. Ini bisa dilihat dengan buah mentah yang dipanen 0%, 1,5% di bawah matang, lebih matang 4,9%, 1,7% abnormal dan 91,9% buah matang. Namun masih ada kesalahan dengan pemanen seperti tangkai panjang yang masih lebih dari 2,5 cm, buah yang tidak dikutip masih 77 buah / ha, dan tandan yang tidak dipanen. Proses pengangkutan buah di PAGE sudah cukup baik. Hal itu bisa dilihat dengan mempercepat proses pengangkutan TBS (Fresh Bunch) dan buah-buahan ke PKS (pabrik kelapa sawit) dengan menggunakan bantuan kontraktor pengangkutan buah sehingga tidak ada buah yang tidak ditranspor.

<p style="text-align: justify;">The purpose of the research was to study the effect of plant population on productivity and water consumption of amaranth in hydroponic technique. Research was conducted in Parung Farm, Bogor, from April to May 2011. The research used Nutrient Film Technique (NFT) hydroponic system that modificated with gravel as its planting medium. The research was arranged in Randomized Complete Block Design with one factor, i.e. , 1, 2, 3, or 4 seedling numbers per hole. The research was divided into two experiment. The first was experiment to study the effect of plant population on plant productivity, and the second was experiment to study the effect of plant population on water consumption of plant. The result showed that plant with one seedling in the planting hole gave the best response on growth of amaranth (plant height, leaves numbers), but for plant productivity, the best result was obtained from plant with three seedlings in the planting hole. Water consumption was highest in plants with one seed per planting hole. Apparently, the more the population, the less consumption of water is needed. This is due to poor root conditions in densely populated. Plant roots will adversely affect the absorption of water.</p><p>Keywords : gravel, hydroponic kit, seedling numbers, the planting hole</p>
