Judul: Yield Models of Perhutani’s Teak Plus Plantation in KPH Balapulang and KPH Pemalang Regional Division of Central Java.
Abstrak: Jati Plus Perhutani (JPP) is a superior variety of teak that has been widely planted and spread in the Perum Perhutani area. The superior type of JPP is expected to replace the conventional teak, which has a very long rotation. This research aims to develop the yield models, and the yield table of JPP stands according to the quality class in which it was grown. The yield model was built based on sample plots that were spreadly ditributed, representing all growing conditions in KPH Balapulang and KPH Pemalang Perum Perhutani Regional Division of Central Java. Selection of the best yield model using non linear regression analysis. The best yield model for estimating growth in diameter, total height, over height, basal area, volume and stand biomass is the Vanclay model. This stand yield model is useful for determining the rotation and yield regulation and as a consideration in silvicultural actions so that the production of Perhutani’s Teak Plus wood can be optimal., Jati Plus Perhutani (JPP) merupakan varietas jati unggul yang sudah ditanam secara luas dan tersebar di wilayah Perum Perhutani. Jenis unggulan JPP diharapkan menggantikan jati konvensional yang memiliki daur sangat panjang. Penelitian ini bertujuan menyusun model hasil dan tabel hasil tegakan JPP sesuai dengan kelas kualitas tempat tumbuhnya. Model hasil dibangun pada plot contoh yang tersebar dan mewakili kondisi tempat tumbuh di KPH Balapulang dan KPH Pemalang Perum Perhutani Divisi Regional Jawa Tengah. Pemilihan model hasil terbaik menggunakan analisis regresi non linear. Model hasil terbaik dalam menduga pertumbuhan diameter, tinggi, peninggi, luas bidang dasar, volume dan biomassa tegakan adalah model Vanclay. Model hasil tegakan ini bermanfaat untuk penetapan daur dan pengaturan hasil serta sebagai pertimbangan dalam tindakan silvikultur agar produksi kayu Jati Plus Perhutani dapat optimal.

Judul: Site Index Identification Perhutani’s Teak  Plus (JPP) Plantation at KPH Pemalang and KPH Balapulang, Regional Division  Perhutani Central Java
Abstrak: Perhutani dengan Jati Plus Perhutani (JPP) menjadi salah satu jenis yang diunggulkan karena cepat tumbuh dan sudah banyak ditanam. Penelitian ini bertujuan menyusun persamaan pertumbuhan peninggi tegakan dan indeks tempat tumbuh untuk tegakan JPP di KPH Pemalang dan KPH Balapulang. Adapun pengukuran diambil pada tegakan JPP berumur 1-20 tahun dengan total 200 plot contoh. Dalam praktiknya, plot contoh dibuat proporsional menurut kelas umur dan kondisi tempat tumbuh yang diambil dari setiap petak tegakan JPP. Indeks tempat tumbuh (ITT) diduga dari peninggi tegakan. Model pertumbuhan peninggi dianalisis menggunakan analisis regresi non-linier dengan tiga model, yaitu Schumacher (1939), Lohrey (1987), Chapman-Richards (Chapman 1961 dan Richard 1959). Model Lohrey menjadi model yang digunakan untuk model pertumbuhan peninggi sekaligus model penduga ITT. ITT tumbuh dibuat dalam 3 kelas, yaitu ITT I untuk kualitas tempat tumbuh baik, ITT II untuk kualitas tempat tumbuh sedang, dan ITT III untuk kualitas tempat tumbuh jelek., Perhutani with Perhutani’s Teak Plus (JPP) is one type that is superior because it grows fast and has been widely planted. The purpose of this study is to compose the equation for the growth of dominan height and growth site index for JPP stands in KPH Pemalang and KPH Balapulang. The measurements were taken on JPP stands aged 1-20 years with a total of 200 sample plots. In practice, sample plots are made proportionally according to age class and site conditions from each JPP stand plot. The ITT is estimated from its dominan height. The growth model was analyzed using non-linear regression analysis using three models, namely Schumacher (1939), Lohrey (1987), Chapman-Richards (Chapman 1961 and Richard 1959). The Lohrey model is the model used for the growth model as well as the site index estimator model. The ITT is made in 3 classes, namely ITT I for good-growing quality, ITT II for moderate growing quality, and ITT III for bad-growing site quality.

Judul: Sarcosporidiasis in slaughter animals
Abstrak: Sarcocystis which belong to the generally occuring parasites for they are found almost all over the countries of the world. Infection of Sarcocystis usually throught inges- tion of feces or flesh of infected animals. The pathogenesis of Sarcosporidiasis is considered as benign but when the Sarcocystis die in a host, sarcocystin or sarcosporidin is liberated thereby which lead to condemnation of meat in the abattoir. Besides condemnation of meat, Sarcocystis also causes: loss of appetite, anemia, lameness, weakness in the lion, diarrhea, fever, pyrexia, paralysis, emaciation, neuro logical disturbances, etc. " Amprolium "at the rate of 100 mg/Kg body weight per day has been practiced for prevention or to minimize Sarco- sporidiasis. Treatment must be started during incubation period. Shedding of Sarcocystis sporocysts in the feces of carnivores is the key factor in the spread of Sarcocystis infection. Therefore, control efforts must be based primarily on measures designed to break the cycle of Sarcocystis.
