Judul: Monitoring Serangan Hyblaea puera Cramer Pada Tanaman
Abstrak: INTRODUCTION. Jati Unggul Nusantara (JUN) is a type of teak trees which is developed from Perhutani Superior Teak (JPP) and is developed further and produced by PT Setyamitra Bhaktipersada and Cooperative of Perumahan Wanabakti Nusantara. Plantation of teak trees often faces the problem of attack by pest. One of the pests which attack teak plantation is Hyblaea puera Cr, which often severely defoliates teak plantation in the beginning of rainy season. According to information the JUN planted by the Cooperative of Perumahan Wanabakti Nusantara (KPWN), is currently attacked by H. puera. The extent of infestation and the development of this pest on JUN plantation owned by KPWN has not been known. Therefore, monitoring of the infestation of H.puera on this plantationis badly needed. MATERIALS AND METHOD. This research comprised the activities of determining observation plots; labeling of trees; and field observation in each plot which include measurement of tree height and diameter, counting the number of trees attacked by H. puera every 2 weeks, counting the total number of leaves and number of young leaves attacked by H.puera in each tree, counting the number of larvae of H. puera present in each tree in each observation plot, and observing other pests occurring in each observation plot. RESULTS AND DISCUSSION. Research results showed that percentage of occurrence of H. puera attack was increasing during the observation period. The highest occurrence at the last observation, 9 October 2008, namely as much as 93.1 %. Intensity of infestation showed fluctuation, with ranged of 12.2 to 12.6 %. Number of H.puera larvae per tree during observation period fluctuated from 0.08 to 1.30 individuals. Number of larvae per 0.1 ha fluctuated from 4.75 to 64.5 individuals. Attack by H.puera during observation did not significantly affect the height and girth of teak stems. Other pests found in this study, beside H. puera were Xyleutus sp, Agrius sp, and white grub of Lepidiota stigma. These pests were considered as being not dangerous yet (insignificant). CONCLUSION. Percentage of occurence by H. puera exhibited increase with time, and intensity of infestation fluctuated from time to time. Number of larvae per tree and per hectare exhibited fluctuation which was due probably to environmental condition, particularly the existence of young leaves which constituted the insect’s food, that could affect the life of H.puera. Attack by H. puera during the observation, did not affect height and girth of teak stems.

Judul: Inventarisasi Hama dan Penyakit pada Pembibitan Tanaman Eucalyptus di Sentra Pembibitan 2 PT RAPP, Kabupaten Pelalawan, Riau
Abstrak: Perkembangan industri pulp dan kertas di Indonesia terus meningkat dari tahun ke tahun sehingga perlu adanya teknologi dan bahan baku yang cukup serta memadai. Bahan baku yang umumnya digunakan berupa jenis kayu hardwood yang telah dipersiapkan di area Hutan Tanaman Industri (HTI). Tanaman Eucalyptus sp. merupakan salah satu jenis tanaman prioritas yang dikembangkan dalam pengelolaan HTI yang diperuntukkan sebagai kayu serat. Salah satu masalah yang dapat mengganggu pertumbuhan tanaman dan mengakibatkan kerugian adalah serangan dari organisme pengganggu tanaman (OPT). Dalam beberapa kasus, serangan penyakit pada tanaman dapat mengakibatkan terhambatnya pertumbuhan tanaman, menurunnya kualitas kayu, bahkan kematian tanaman. Penelitian bertujuan mengetahui jenis-jenis hama dan penyakit, serta budi daya tanaman Eucalyptus dari sampel bibit bergejala yang diambil dengan metode purposive sampling di Sentra Pembibitan 2 PT RAPP, Kecamatan Pangkalan Kerinci, Kabupaten Pelalawan, Riau. Identifikasi patogen dilakukan dengan membandingkan hasil pengamatan gejala serta tanda di lapangan dan laboratorium dengan literatur. Inventarisasi hama dilakukan dengan studi literatur berdasarkan data hama ditemukan yang telah tersedia. Penyakit yang menyerang bibit Eucalyptus adalah bercak daun Quambalaria, bercak daun dan batang Cylindrocladium, bercak daun Kirramyces, layu pucuk dan daun Rhizoctonia, dan hawar daun Xanthomonas. Hama yang ditemukan menyerang bibit tanaman Eucalyptus, yaitu ulat penggulung daun (Strepsicrates macroptena), tungau, kutu kebul (eucalyptus whitefly), thrips (Thrips autralis), wereng, kutu daun, dan Helopeltis theivora., The development of the pulp and paper industry in Indonesia continues to increase from year to year, which requires adequate technology and raw materials. Raw materials that are generally used are hardwood species that have been prepared in the Industrial Plantation Forest (HTI) area. Eucalyptus sp. is one of the priority plant species developed in HTI management which is intended as fiber wood. One of the problems that can interfere with plant growth and cause losses is the attack of plant pest organisms (OPT). In some cases, disease attacks on plants can result in inhibition of plant growth, decreased wood quality, and even plant death. This study aims to determine the types of pests and diseases, as well as the cultivation of Eucalyptus from symptomatic seedling samples taken by purposive sampling method at PT RAPP Nursery Center 2, Pangkalan Kerinci District, Pelalawan Regency, Riau. Pathogen identification was carried out by comparing observations of symptoms and signs in the field and laboratory with the literature. Pest inventory was conducted by literature study based on available pest data. Diseases that attack Eucalyptus seedlings are Quambalaria leaf spot, Cylindrocladium leaf and stem spot, Kirramyces leaf spot, Rhizoctonia shoot and leaf wilt, and Xanthomonas leaf blight. Pests found attacking Eucalyptus seedlings were leafroll caterpillars (Strepsicrates macroptena), mites, whitefly (eucalyptus whitefly), thrips (Thrips autralis), leafhoppers, aphids, and Helopeltis theivora.

Judul: Sifat fisik dan kandungan Fe Meatloaf yang menggunakan tepung daging sapi sebagai bahan baku
Abstrak: Meatlof merupakan produk yang serupa dengan sosis. Hal yang membedakannya ialah pada meatloaf dilakukan pengisian ke dalam loyang dan dipanggang pada suhu 180 °C selama 30 menit. Meatloaf biasanya terbuat dari daging segar, yang memiliki nilai gizi yang tinggi, baik dari segi nilai biologis, kecernaannya maupun kelengkapan asam aminonya dibandingkan bahan nabati, namun masih dinilai sebagai bahan pangan yang sifatnya perishable (mudah rusak). Pembuatan tepung daging melalui proses freeze drying bertujuan untuk meningkatkan umur simpan dan memudahkan pemanfaatannya dalam pembuatan produk olahan. Penggunaan tepung daging sapi dalam pembuatan meat loaf daging sapi diharapkan menjadi alternatif dalam pemenuhan kebutuhan protein hewani dan menjadi langkah awal untuk inovasi teknologi pembuatan meatloaf daging sapi yang praktis.
