Abstract

ABSTRAK Penelitian ini  bertujuan untuk mendapatkan model hipotetis penjarangan hutan tanaman jenis ekaliptus (Eucalyptus  grandis  Hill  ex  Maiden)  berdasarkan  pendekatan  analisis  sistem.  Pada  saat  ini  di  lokasi penelitian kegiatan penjarangan belum dilakukan karena orientasi pengusahaan masih pada hasil biomassa. Model sistem yang dibangun digunakan untuk mengetahui waktu dan intensitas penjarangan yang optimal. Berdasarkan simulasi terhadap berbagai skenario preskripsi penjarangan, intensitas penjarangan 25 % dengan rotasi penjarangan 15 tahun memberikan hasil maksimal sebesar 40,7 m3 per ha per tahun atau 610,5 m3 per ha tegakan dengan rata-rata diameter 39,0 cm. Hasil total tersebut diperoleh dari kegiatan penjarangan sebesar 80,1 m3  per ha dan hasil tebangan akhir daur sebesar 530,4 m3  per ha. Model yang dibangun merupakan model hipotetis sehingga validasi sangat perlu dilakukan dengan membangun petak ukur penjarangan di lapangan.

Abstract

ABSTRAK Penelitian ini bertujuan untuk mendapatkan model analisis sistem dinamika struktur tegakan dan pengaturan hasil hutan rawa tidak seumur di Riau. Model disusun berdasarkan pada seri data petak ukur permanen di hutan alam bekas tebangan pada kawasan pengusahaan hutan PT. Diamond Raya Timber, Provinsi Riau. Dinamika struktur tegakan terdiri atas ingrowth, upgrowth, dan mortality. Model yang dibangun didasarkan pada kelompok jenis (Dipterocarpaceae, non-Dipterocarpaceae, dan non-komersial). Hasil simulasi menunjukkan bahwa dengan siklus tebang 35 tahun, tegakan pada siklus tebang kedua belum mencapai kondisi semula. Memperpanjang siklus tebang hingga 40 tahun atau menurunkan limit diameter hingga kelas diameter 40 cm merupakan alternatif untuk menjaga kelestarian hasil. Siklus tebang yang semakin panjang ini juga didukung oleh riap diameter yang lebih kecil dari satu cm/tahun yang menjadi dasar penetapan siklus tebang 35 tahun.

Abstract

ABSTRAK Penelitian ini  bertujuan untuk  mendapatkan informasi tentang persepsi dari berbagai lembaga strategis terhadap  setiap  kriteria  indikator Pengelolaan Hutan  Alam Produksi  Lestari (PHAPL),  hasil  pengujian penerapan kriteria dan indikator, permasalahan yang muncul, dan hasil perumusan berbagai strategi pengelolaan hutan lestari. Hasil menunjukkan bahwa pemenuhan kriteria prasyarat memiliki bobot tertinggi terhadap pencapaian pengelolaan hutan lestari khususnya indikator kepastian kawasan unit manajemen. Disadari oleh masing-masing stakeholder bahwa kepastian status unit manajemen merupakan dasar dari kepastian pengusahaan hutan dan ketidakpastian, hal ini merupakan akar dari konflik yang terjadi antara masyarakat dengan pemegang konsesi Hak Pengusahaan Hutan (HPH). Masalah ini juga diakibatkan oleh tidak terakomodasikannya kepentingan masyarakat terhadap sumberdaya hutan. Oleh karena itu strategi pemecahannya harus diarahkan pada penetapan kepastian kawasan, perbaikan pasar perkayuan (termasuk pengatasan illegal trade), dan pengikursertaan masyarakat dalam kegiatan pengelolaan hutan. Dalam implementasi penilaian kriteria dan indikator PHAPL, mekanisme penilaian yang terlalu spesifik dan kaku cenderung menyulitkan penilai untuk mengakomodasikan dinamika perubahan yang terjadi dan juga cenderung lebih bersifat teknis  prosedural, sehingga diperlukan perumusan kembali  terutama berkaitan dengan berbagai aspek gangguan dan kondisi spesifik hutan alam produksi.

Abstract

Salah satu jenis potensial untuk rehabilitasi hutan dan lahan di DTA Danau Toba adalah Macadamia integrifolia. Selain adaptif pada lahan kritis, pohon ini menghasilkan buah yang dapat dimakan dan bernilai ekonomi. Sehingga diperlukan upaya pembangunan sumber benihnya di kawasan ini. Tujuan kegiatan ini adalah untuk pengetahui karakteristik buah, benih dan penyemaian Macadamia (Macadamia integrifolia) yang berasal dari Hutan Penelitian Sipisopiso, Danau Toba Sumatera Utara. Penelitian yang dilakukan meliputi penanganan buah; penangan benih/biji dan penyemaian benih. Hasil penelitian menunjukkan rata-rata berat buah basah adalah 7,51 g atau terdapat 141 buah per 1 kg. Berat rata-rata benih adalah 5,83 atau 181 biji dalam satu kilogramnya. Benih mulai berkecambah pada hari ke 26 dengan masa kecambah benih selama 70 hari. Daya kecambah tertinggi terdapat pada benih yang tidak mendapat perlakuan perendaman (kontrol). Perlakuan peretakan benih mampu mempercepat perkecambahan benih. Benih yang direndam dengan air dingin selama 24 jam mampu meningkatkaan daya kecambah hingga 78%. Berdasarkan pertumbuhan awal selama 6 bulan di persemaian, kecambah memiliki tinggi rata-rata 13,7 cm dengan  diameter 3,2 mm.

Abstract

The aim of the study was to determine the effect of the administration of probiotics Em-4 and the length of ripening on the digestibility of dry matter and organic matter from complete feed made from basal sugarcane leaves in vitro. The implementation of in vitro research, analysis of dry matter and organic materials was carried out in the Lab. Nutrition and Feed of Universitas Brawijaya Malang. The research design used was Factorial Completely Randomized Design (CRD) with 6 treatments and 4 replications consisting of: factor I: complete feed with basal sugar cane leaf ingredients Factor II: Duration of curing, so that the number of experiments was 24 units. The parameters observed in this study were dry matter digestibility (DMD), digestibility of organic matter (OMD). The results showed that the old treatment for ten days of ripening could produce 49.42% organic matter digestibility and 43.07% dry matter digestibility. Further research is needed for the use of complete sugar cane leaves with the addition of feed additives that can improve dry matter digestibility and digestibility of organic matter. Tujuan penelitian untuk mengetahui pengaruh pemberian probiotik Em-4 dan lama pemeraman terhadap kecernaan bahan kering dan bahan organik pakan komplit berbahan basal daun tebu secara in vitro. Pelaksanaan penelitian in vitro, analisa bahan kering dan bahan organik dilaksanakan di Lab. Nutrisi dan Pakan Universitas Brawijaya Malang. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) Pola Faktorial dengan 6 perlakuan dan 4 ulangan, terdiri dari: faktor I:pakan komplit dengan bahan basal daun tebu Faktor II:Lama pemeraman, sehingga jumlah percobaan sebanyak 24 unit. Parameter yang diamati dalam penelitian ini adalah kecernaan bahan kering (KcBK), kecernaan bahan organik (KcBO). Hasil penelitian menunjukkan perlakuan lama pemeraman sepuluh hari dapat menghasilkan kecernaan bahan organik sebesar 49,42 % dan kecernaan bahan kering sebesar 43,07 %. Diperlukan penelitian lebih lanjut penggunaan pakan komplit daun tebu dengan penambahan feed additive yang mampu memperbaiki kualitas kecernaan bahan kering dan kecernaan bahan organik.

Abstract

Macrobrachium rosenbergii (De Man, 1879) is a freshwater prawn species that have a high economic value because of its relatively large size compared to the other freshwater prawn species. Exploration to find this species in the Maraja River, Toli-Toli, Central Sulawesi was carried out in January 2019. Sample collected using tray net. Two male specimens of M. rosenbergii were found in the river, with maximum size of carapace length reaching 45.94 mm. Macrobrachium rosenbergii has been found in habitats with clay substrate and slow flowing current. This record extended the distribution of M. rosenbergii, whose spread in Sulawesi has been known only in the southern part of the island, such as in Makassar, Bone, Pinrang, Wajo and Luwu. In this paper, the morphological characters and line drawing of some character M. rosenbergii from the Maraja River were provided.
