    Abstract: Sago plants can be used from leaves, fronds, and stems with the main product of sago starch from the stem. In the production process, the sago plants used are 7-8 years old. The productivity of sago palms in Pemakuan Laut village is around 200 kg starch/stem with a selling price of Rp. 3,500/kg in wet conditions and Rp. 7,500/kg of dry sago flour. Sago processing waste has not been utilized yet by the community even though the waste can still be used for other purposes such as animal feed, hardboard, fuel, plant growth media, and fertilizer. Sago waste is a problem in the Pemaku Laut village environment because the waste has accumulated while the location for disposing of it is limited. Therefore, in this community service activity training was carried out in making animal feed (poultry) using sago dregs. The method used is fermentation. From the activities carried out, it was known that all the participants had started to utilize sago dregs, but the preliminary process had not been carried out, the dregs were directly given to livestock. In this training, sago dregs processing is carried out using the fermentation process. From the training, it can be seen that the community already knows the process of processing the dregs before giving it livestock to increase its nutritional value.

    Abstract: Kayu jelutung ( 〈 i 〉 Dyera costulata 〈 /i 〉 ) merupakan salah satu jenis tanaman endemik di Kalimantan yang mulai langka. Tujuan penelitian ini adalah untuk menganalisis karakteristik pertumbuhan kayu jelutung yang dibudidayakan oleh masyarakat di Kalimantan Tengah di lahan gambut. Pengolahan lahan dengan tanpa bakar menjadikan hutan tanaman rakyat (HTR) ini ramah lingkungan. Sebanyak 38 pohon jelutung dari 1 blok HTR diukur diameter dan tinggi pohonnya, selanjutnya dikelompokkan dalam kategori pertumbuhan cepat, sedang, dan lambat. Dari masing-masing kelompok diambil 1 pohon yang memenuhi persyaratan. Sampel setebal 2 cm diambil dari ketinggian 1,3 m dari permukaan tanah dan setiap 2 meter ke arah ujung pohon untuk pengukuran kadar air (KA), berat jenis (BJ), anatomi kayu, nilai turunan serat, dan kandungan kimia kayu. Hasil pengujian menunjukkan bahwa kayu jelutung memiliki BJ rendah dan serat pendek sehingga termasuk kelas 2 untuk pembuatan pulp dan kertas. Kandungan kimia kayu jelutung menunjukkan kandungan ektraktif larut alkohol benzena yang cukup rendah dan bisa digunakan sebagai bahan baku pulp dan kertas. Selain itu, kayu jelutung juga sesuai untuk digunakan sebagai bahan kayu lapis. Characteristics of Jelutong Wood (( 〈 i 〉 Dyera costulata 〈 /i 〉 ) from Community Forest in Central KalimantanAbstractJelutong wood ( 〈 i 〉 Dyera costulata 〈 /i 〉 ) is one of the endemic tree species in Kalimantan which is starting to become scarce. This research aims to analyze the growth characteristics of jelutong wood planted by the community in peatland in Central Kalimantan. Land processing without burning makes this community plantation forest environmentally friendly. Thirty-eight trees of jelutong from one block were measured diameter and three height, end then categorized to fast, medium, and slow-growing. One tree from each category was harvested. Two centimeters of the disk were collected from each harvested trees from a 1.3 meter height and continued every 2 meters to the peak of trees to measure water content, specific gravity, anatomical properties, derived wood, and chemical content of jelutong wood. From the analyses, jelutong has low specific gravity and short fibers, categorized into class two for pulp and paper raw materials. Extractive content in alcohol benzene from jelutong wood was low that preferable for pulp and paper. On the other hand, jelutong wood is suitable for plywood raw materials.

    Abstract: This study aims to determine the color of a sample qualitatively on jelutung wood including the base, middle, tip, and bark. Changes in color using a photometer are not only found in every type of wood, but also affect the position of the height on the stem. Color changes are generally influenced by extractive composition, temperature, humidity, light, and storage conditions (Sahin 2011). The color of the wood needs to be considered for pulp and paper, because the brighter the color of the wood, the better the quality of the pulp and paper produced. Jelutung wood has a smooth texture, the direction of the fibers is straight, and the slippery surface is slightly glossy so it is suitable for writing paper. And it can also be used as pulp and paper with the addition of chemicals and advanced treatment. Color change usually occurs due to the presence of substances that react before and after treatment on a sample.Penelitian ini bertujuan untuk mengetahui warna suatu sampel secara kualitatif  pada kayu jelutung meliputi pangkal, tengah, ujung, dan kulit. Perubahan warna menggunakan fotometer  pengukurannya tidak juga  terdapat pada suatu jenis kayu yang berbeda, tetapi juga berpengaruh pada letak ketinggian pada batang. warna yang berubah pada umumnya dipengaruhi oleh sifat komposisi dari kadar ekstraktif, suhunya, kelembabannya, cahaya matahari, dan kondisi dimana sampel kita simpan (Sahin 2011). Kayu yang berwarna perlu diperhatikan pada pulp dan kertas, sebab warna kayu yang semakin cerah akan menentukan kualitas pulp dan kertas yang bagus pula. Kayu jelutung memiliki tekstur halus, arah seratnya lurus dan permukaan licin sedikit mengkilap sehingga cocok diperuntukkan sebagai kertas tulis. Dan juga bisa diperuntukkan menjadi kertas dan pulp dengan menambahkan bahan bahan kimia juga dilakukan perlakuan lebih lanjut. Colour Change atau perubahan warna biasa terdeteksi sebab terdapatnya kandungan yang bereaksi antara zat sesudah dan sebelum perlakuan pada sampel.
