The aim of this research is to measure the light intensity change under the tree due to the change of crown tree density in agro forestry system. The factorial completely randomized block design with four replications was applied on this research. The first factor were species in agro forestry system namely: mahagony (Switenia mahagony), teak (Tectona grandis), para-serianthes (Paraserianthes falcataria) and mangium (Acacia mangium). The age of the species mentioned above is five years old. Second factor were crown tree pruning including; without pruning (0%), pruning 50%, and pruning 75%. The result showed that the light intensity in open area is 1150 μmole m-2 sec-1.The average of light intensity under the crown tree of mahagoni, teak, paraserianthes and mangium were 830, 607, 443 and 403 μmole m-2sec.-1, respectively. The light intensity under the tree without pruning was 497 μmole m-2 sec-1, whereas with 50% and 75% of pruning increased light intensity up to 554 and 661 μmole m-2 sec.-1, respectively. Cassava tuber yield in agro forestry system were 5.4; 3.2; 3.7 and 1.2 Mg ha-1 respectively under mahagony, teak, paraserianthes and mangium, respectively. The yield of cassava in agro forestry system was lower than monoculture system (26.9 Mg ha-1). Keywords: crown tree, mahagony, teak, paraserianthes, mangium, cassava, agroforestry system

Peatland is a unique ecosystem with water saturation; peatland regulates hydrological processes, climate, environmental conditions, and biodiversity. Poor management practises regarding peatlands can lead to land degradation, and peatland degradation typically has negative effects. Recent tropical peatland research in Indonesia has predominantly revolved around the examination of the ecological consequences resulting from various management approaches. There is little study on farmers' agroforestry efforts to preserve and restore degraded peatlands. A comprehensive examination was undertaken to assess a range of facts, information, and scholarly articles pertaining to the practise of agroforestry on peatlands in Indonesia. The primary incentive for farmers to adopt agroforestry systems originates from their recognition of the impending scarcity of trees. By integrating intercrops with cultivated trees, farmers anticipate generating adequate money to fulfil their family's economic requirements. Farmers who choose intensive intercropping practises are motivated by market demand, whereas farmers who do not adopt this approach tend to favour crops that necessitate less rigorous management. The provision of governmental assistance holds significant importance, and there is a pressing need for additional guidance and support. The potential for rehabilitating degraded peatlands by the implementation of agroforestry practises of native tree species is considerable. Their growth patterns contribute to enhanced vegetative coverage, resulting in heightened moisture levels, reduced temperatures, diminished fire hazards, and improved peat soil quality. The relationship between the physiography of the land and the depth of the peat is directly associated with the patterns and components of agroforestry in peatland environments.

The purpose of this training is to increase the understanding of journal managers regarding journal management, especially with regard to national and international indexing, and improve journal management competence (skills) related to how to manage journals, especially related to national and international indexing. Based on the results of the analysis of the responses of the training participants, it can be concluded that: The scientific journal management training that was carried out was very useful in improving the quality of scientific journal management in the IAIN Palangka Raya area in particular and in the city of Palangka Raya in general. of course Have a direct positive impact on increasing the acceptance of scientific journals. In addition, from the participants' responses during the training and mentoring it was concluded that: Improving the quality of management of scientific journals is a very basic component affecting the quality of published journals

Pertumbuhan tanaman pakcoy sangat bergantung pada tingkat pH tanah media tanam. Salah satu upaya untuk meningkatkan pH tanah gambut rendah adalah dengan menggunakan serbuk cangkang telur ayam yang mengandung kalsium (Ca) sebesar 35,1-36,4%, lebih tinggi dibandingkan dengan kandungan kalsium pada kapur dolomit yang sebesar 21,70%. Tujuan penelitian ini adalah untuk menguji respons pertumbuhan dan hasil tanaman pakcoy terhadap pemberian serbuk cangkang telur ayam. Kemudian juga berupaya untuk menentukan dosis serbuk cangkang telur ayam yang dapat memberikan hasil terbaik pada tanaman pakcoy di tanah gambut. Selain itu, penelitian ini juga bertujuan untuk menguji respons pemberian serbuk cangkang telur ayam dalam meningkatkan pH tanah gambut pada budidaya tanaman pakcoy. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktor tunggal untuk mengetahui perbedaan respons serbuk cangkang telur (T) terhadap dosis yang diberikan. Dosis serbuk cangkang telur yang digunakan sebanyak 1 t ha-1, 2 t ha-1, 3 t ha-1, 4 t ha-1, dan 5 t ha-1. Penelitian ini menunjukkan adanya korelasi positif antara dosis serbuk cangkang telur dengan pertumbuhan dan hasil tanaman. Secara khusus, dosis 5 t ha-1 serbuk cangkang telur memberikan hasil yang paling baik dalam hal lebar daun tanaman (7,1 cm) dan hasil tanaman (186,5 g tanaman-1). Selain itu, peningkatan dosis lebih lanjut dapat memberikan hasil yang lebih optimal pada tanaman pakcoy. Penambahan serbuk cangkang telur ayam pada tanah gambut menghasilkan kenaikan pH sebesar 0,89-1,59 poin sehingga menaikkan pH tanah dari 3,21 menjadi 4,8 dengan dosis 5 t ha-1.

The cultivation of oyster mushrooms is an activity that can be introduced to early childhood as an effective learning medium. This activity not only familiarizes children with the growth process of oyster mushrooms but also increases their awareness of the importance of the environment and sustainability. At the Experimental Garden Installation of the Faculty of Agriculture, University of Palangka Raya, this program is designed to provide a fun and educational learning experience for the Early Childhood Education (PAUD) Tiara Az Zahra. Through the introduction of oyster mushroom cultivation, it is expected that children can develop observation skills, knowledge about the life cycle of mushrooms, and awareness of the importance of mushrooms as a nutritious vegetable source in everyday life. Additionally, this activity also aims to bring children closer to the world of science from an early age, as well as teach values of cooperation and responsibility through practical and interactive activities.
