Abstract

The Growth of Teak Plantation Forest in East Kalimantan. Teak is one of the most important tropical timber in the international timber market because of the various advantages it has and the type of wood that is very valuable for forestry plants. Teak has been known and cultivated for a long time, particularly in Java. In East Kalimantan, Teak has been developed by public and private companies , with a growth of diverse.The growth of teak stands in East Kalimantan in general showed a decline in growth with increasing stand age; diameter and height growth of stands highest in the early phase of growth in the range of 1-5 years of age, then decline gradually and growth has declined after the 12 year old stands; up to 12 year old stands generally teak growth in East Kalimantan showed growth (increment) in diameter and a height higher than the other locations teak plantation in Java.

Abstract

The Important Ecosystem Area of ​​Mesangat Suwi Wetlands has a total area of ​​around 14,722.69 ha located in East Kutai Regency, East Kalimantan. These wetlands have a strategic role as a regulators of the upstream water system, a source of freshwater fisheries, and a habitat for important protected animals. This study aimed to determine the rate of suspended sediment transport and river water quality. The study was conducted in two stages, the first was data and sample collection in the field, and the second was laboratory testing. The results of the study showed that the river water discharge and TSS in the Suwi and Masangat Rivers at the study location were directly proportional to the height of suspended sediment. The total average of suspended sediment in Suwi was smaller, it's 0.79 tons/year compared to Masangat at 2.64 tons/year. suspended sediment grains could settle and become bottom sediment. The rate of sedimentation in the river would accelerate the shallowing process which affected the wetlands ecosystem. The reduction in vegetated or forested areas in the Masangat wetlands was due to high human activity compared to Suwi. Currently, the water quality in the study areas, including COD, BOD, TDS, and TSS, is generally still below the standard quality threshold and is categorized as class two, namely water that can be used for freshwater fish farming, recreational facilities, livestock farming, and can be used to irrigate crops or rice fields.

Abstract

Kebakaran hutan berdampak terhadap sifat fisika, kimia tanah, biologi tanah, erosi, kapasitas menyimpan air tanah, penghilangan serasah serta humus. Tujuan penelitian ini adalah untuk mengetahui dampak kebakaran hutan terhadap sifat fisik dan sifat kimia di Prevab, Taman Nasional Kutai. Tujuan penelitian didekati dengan membandingkan areal bekas terbakar dan areal tidak terbakar. Pengujian sampel tanah dilakukan di laboratorium, selanjutnya dilakukan analisis data dengan mengacu pada kriteria penilaian sifat fisik dan kimia tanah yang telah ditetapkan. Berdasarkan penelitian ini diperoleh hasil bahwa sampai 19 tahun setelah terbakar, diketahui kebakaran hutan berdampak terhadap sifat fisik tanah, yaitu meningkatnya kerapatan lindak/Bulk Density, penurunan porositas dan permeabilitas tanah serta tekstur tanah dengan fraksi pasir lebih dominan. Sifat kimia tanah memiliki kriteria yang sama antara areal bekas terbakar dan tidak terbakar yaitu pH sangat masam, DHL sangat rendah dan KTK rendah, sedangkan untuk kation-kation basa secara umum lebih tinggi pada areal tidak terbakar dibandingkan dengan areal terbakar, kecuali untuk Kalium (K).

Abstract

Dalam budidaya tanaman kehutanan, tanah merupakan media pertumbuhan tanaman yang utama. Berbagai tipe penggunaan lahan (tanah) dapat mempengaruhi sifat-sifat tanah, antara lain sifat morfologi dan fisik tanah. Tujuan Penelitian untuk mengetahui perkembangan morfologi tanah pada tegakan jati, yang diharapkan dapat mendukung upaya keberlanjutan pengelolaan tanah dan tegakan. Dengan membuat profil tanah, maka pengamatan dan identifikasi sifat morfologi tanah dapat dilakukan. Hasil penelitian menunjukkan bahwa tanah memiliki kedalaman yang dalam, batas horizon berombak dengan peralihan horizon baur; warna tanah semakin terang dan perakaran tanaman semakin berkurang dengan bertambahnya kedalaman tanah; bercak tanah dijumpai pada horizon 3 dan 4; tingkat kemantapan struktur dan konsistensi tanah semakin meningkat dengan bertambahnya kedalaman tanah. Penelitian serupa dapat dilakukan pada jenis tanah dan tutupan lahan yang berbeda, secara berkala dan sifat-sifat tanah yang lain (fisik, kimia dan biologi).
