Judul: Penilaian Model Jaringan Jalan untuk Pengangkutan Kopal dan Getah Pinus di Hutan Pendidikan Gunung Walat Sukabumi Jawa Barat
Abstrak: There are three types of transportation in Gunung Walat University Forest (GWUF), which are copal carrying, pine resin carrying, and pine resin transportation. Roadnetwork and other opening forest area construction are built to support the copal and pine resin transportation. Roadnetwork in GWUF are consist of main road, branch road, and pathway. Data was collected by two methods, they are field data collection and measurement and planning alternatives roadnetwork of copal and pine resin transportation on maps using ArcView GIS 3.3 software, which is appraised by three aspects, they are ecological, economic, and social. Based on three aspects are specified as the basis for quantification of several indicators. Intensity of opening forest area in GWUF is fall under the mid-level category with the main road density is 15,90 m/ha and the branch road density is 18,10 m/ha. The status quo FJP score is 1,87 with JPS as far as 988,52 m and JPT as far as 528,12 m. The three alternative model have a mid-level PWH intensity. Alternative III has the smallest FJP score in 1,28 with JPS as far as 716,24 m and JPT as far as 561,69 m. The cost of road construction of alternative I, alternative II, alternative III, respectively is Rp. 315.359,00, Rp. 991.697.019,00, and 1.682.150.385,00. Alternative III has the highest cost due to the redesigning of the entire status quo roadnetwork. Alternative III has the highest productivity per km on pine resin carrying and pine resin haulage, which is, respectively, 137,55 kg/km/hour and 275,42 kg/km/hour. On the other hand, model of transportation with the highest productivity of copal carrying is alternative II with 801,61 kg/km/hour. Based on the benefit value analysis method, alternative III is chosen as the best copal and pine resin transportation alternative due to the highest total of the sum of class placement.

Judul: Evaluation Of Forest Road Network in RPH  Wungu Perum Perhutani KPH Madiun East Java
Abstrak: Kegiatan utama pembukaan wilayah hutan adalah pembuatan dan pemeliharaan jalan yang didalamnya memerlukan perencanaan yang tepat sehingga mampu menjamin kelancaran pengelolaan hutan khususnya pemanenan. Penelitian ini dilakukan di RPH Wungu, BKPH Dungus, Perum Perhutani KPH Madiun Jawa Timur yang merupakan kelas perusahaan kayu jati. Karakteristik jaringan jalan angkutan pada RPH Wungu digambarkan oleh beberapa parameter PWH yaitu kerapatan jalan (WD), spasi jalan (WA), jarak sarad rata-rata secara teoritis (REo), jarak sarad rata-rata terpendek di lapangan (REm), jarak rata-rata sebenarnya di lapangan (REt), kerapatan jalan optimal (Dopt) dan persen pembukaan wilayah (E %), yang besaran nilainya bergantung dari panjang jalan yang dibuat dan luas wilayah hutan. Hasil perhitungan karakteristik jaringan jalan pada PWH mempunyai kerapatan jalan (WD) = 21,61 m ha־ˡ, spasi jalan (WA) = 462,74 m, jarak sarad rata-rata teoritis (REo) = 115,68 m, jarak sarad rata-rata sebenarnya di lapangan (REt) = 195,92 m, jarak sarad rata-rata terpendek (REm) = 134,19 m, tebal lapisan pengerasan jalan minimal = 13,07 cm, persen pembukaan wilayah hutan (E %) = 86,7 %, dan kerapatan jalan optimal (Dopt) = 20,67 m ha־ˡ. Secara umum jaringan jalan hutan pada PWH tingkat RPH sudah dapat melayani kegiatan pengelolaan hutan terutama kegiatan pemanenan., The main activity of forest opening is a building and maintaining road needed to ensure forest mangement especially for forest harvesting activites. The research is conducted in RPH Wungu, BKPH Dungus, KPH Madiun, Perum Perhutani Regional Division East Java which is forest plantation for producing teakwood. The harvesting road in RPH Wungu is depicted by some parameters forest opening which aare road density (WD), road spacing (WA), the skid distance theoretical average (REo), the shortest average skid distance (REm), the average skid distance (REt), optimum road density (Dopt) and percent clearing forest area (E %) which is the value depends on road lenght built and forest area. The calculation result of the transportation road network characteristics in forest opening is road density (WD) = 21,61 m ha־ˡ , road spacing (WA) = 462,74 m, the skid distance theorical average (REo) = 115,68 m, the average skid distance (REt) = 195,92 m, the shortest average skid distance (REm) = 134,19 m, thickness road pavement = 13,07 cm, percent clearing forest area (E %) = 86,7 % , and optimum road density (Dopt) = 20,67 m ha־ˡ. To sum up, forest road system in forest opening for compartement sample has accomodated all forest management activities mainly for forest harvesting activities

Judul: Enteric Collibacillosis Pada Anak Babi Baru Lahir: Patogenesa dan Perubahan-Perubahan Patologisnya
Abstrak: Diare disebabkan oleh infeksi bakteri Escherichia coli pada anak-anak babi baru lahir yang peka terhadap en terotoksin produk bakteri tersebut. Dikenal sebagai colibacillosis. Patogenesa dari colibacillosis anak babi baru lahir adalah (1) infeksi oleh E. coli patogen, (2) proliferasi E. coli di lumen usus halus, (3) produksi dan pelepasan enterotoksin, dan (4) aktifitas toksin pada usus halus. Dalam proses proliferasi, adanya antigen pili K88 sangat penting karena memungkinkan bakteri perlekatan dengan epitel mucosa usus halus. mengadakan Setelah ko lonisasi dan proliferasi segera toksin dilepaskan. Akti- fitas toksin menginduksi sekresi yang berlebihan dari u- sus sehingga banyak cairan yang dikeluarkan ke lumen usus. Hal ini mengakibatkan banyak cairan dan elektrolit hilang sehingga timbul diare, dehidrasi dan asidosis yang sering menyebabkan kematian. Perubahan-perubahan patologis yang umum adalah dis tensi usus halus, dilatasi lambung dan infark pada kurva- tura mayor. Perubahan-perubahan histologis yang terjadi adalah enteritis hemorrhagica acuta, oedem dan kongesti pembuluh darah di lamina propria, akumulassi leukosit inti polimorf, sel monosit, dan inti sel mengalami piknosis Thrombus pada vena dan degenerasi serta desquamasi sel epitel usus….
