Abstract

This research aims to find out the best formulation of pine cones in making biopesticides, find out the processing of pine waste in overcoming pest problems in spinach plants and the growth of spinach plants that have been given biopesticide made from pine cones. biopesticide standard. The treatment used was a combination of biopesticide and pine cones with a ratio of L0 = control (without biopesticide), L1 = 1:10:3:1, L2 = 1:10:3:3, L3 = 1:10:3:6, Each treatment was repeated 3 times. Making biopesticide uses 250 ml of acetone solution, 6 liters of clean water, and pine fruit waste according to a predetermined formulation. It is hoped that the results of this research will be able to utilize pine cones in everyday life to become an economically valuable product to ensure the fulfillment of food needs in supporting food security and independence programs.

Abstract

Arbuscular Mycorrhiza Fungi (AMF) can be used as a biofertilizer or biological fertilizer so that it increases the absorption of nutrients needed by plants such as P, K, Ca, Mg, Fe. The purpose of this study was to test the effectiveness of the use of arbuscular mycorrhizal fungi fertilizer on the growth of matoa seedlings in post-gold mining soil media. This study used a Randomized Block Design (RAK) with arbuscular mycorrhizal fungi treatment on each plant, including: Control (A), 5 g AMF (B), 10 g AMF (C), 15 g AMF (D). The results showed that the inoculation treatment of 15 g AMF was able to increase the average percentage of root colonization (72.21%), plant height (5.19 cm), diameter (0.80 mm), dry weight of shoots (1.93 g), and seedling quality index (0.26). Therefore, AMF can play a role in increasing the growth of matoa seedlings in nutrient-poor soil, especially post-gold mining soil on a plastic house scale. Therefore, FMA can play a role in increasing the growth of matoa seedlings in nutrient-poor soil, especially post-plastic house-scale gold mining soil.

Abstract

The Royal Palm (Roystonea regia) is a type of monocotyledonous plant that is widely planted, especially as an ornamental plant that is part of the urban landscape. However, in its growth, there is a natural cycle where the royal palm leaves will fall and end up as waste. In this case, the royal palm leaf sheath is thought to have potential as a composite reinforcement material. However, in its utilization as a composite reinforcement material, basic information such as the physical and mechanical characteristics of the material needs to be known. The purpose of this study was to evaluate the physical and mechanical properties and potential utilization of the royal palm leaf sheath. The research shows that the green royal palm leaf sheath's water content and density are higher than the brown leaf sheath. In addition, the dimensional stability of the green leaf sheath is higher than that of the brown leaf sheath. The tensile strength of the green conditions is lower than that of the brown conditions, and the strength decreases towards the core of the royal palm leaf sheath. Meanwhile, the tensile strength of the fibers from the two leaf sheath conditions is not significantly different. This test shows that the royal palm leaf sheath fiber is classified into fiber class II. This shows that the royal palm leaf sheath has the potential as a composite reinforcement material.

Abstract

This research is descriptive qualitative research that aims to explore and analyses the role of benefits, obstacles and involvement of Fire Care Community (MPA) formed by Regional Technical Implementation Unit (UPTD) of Balikpapan Protected Forest Management Unit (KPHL). Primary data consists of interviews, observations and documentation and secondary data comes from literature, reports or documents from related institutions, while the object of research is five MPA groups in Karang Joang Village Balikpapan City, East Kalimantan Province selected by purposive sampling and analyzed using a Likert Scale. The research shows that Fire Care Community (MPA) in Karang Joang Village. It is crucial in promoting awareness about the risks of forest fires through impactful outreach and education, fostering a shift in people’s behavior toward more eco-friendly practices. The existence of MPA provides significant benefits, such as ecosystem preservation, improved air quality, public health, as well as supporting sustainable agricultural practices that strengthen local economic welfare. Although MPAs face barriers such as limited resources and weak law enforcement, these challenges can be overcome with stronger collaboration. MPA engagement has also proven effective in reducing the frequency and scale of forest fires through regular patrols, early detection and rapid response

Abstract

This research aims to determine community perceptions in forest management based on forest characteristics and forest management models in the Liawan Sub-watershed, Mamasa Watershed. Management and utilization of Indonesia's forest potential must be accompanied by maintaining and restoring previously existing ecosystem functions in order to maintain the preservation of forest ecosystems. Nevertheless. Local communities also act as conservator agents apart from only utilizing the potential of forest resources as well as a component of its management. Until the early 1970s, the local wisdom of very diverse communities still dominated forest management systems throughout Indonesia, especially outside Java. Indigenous communities, which have not had much intervention from exploitative government policies, still manage their customary forests autonomously to ensure the continuity of community life. The local knowledge of the people who live in the Liawan Sub-watershed is very important to know that the people still maintain the proper order of water sources. People living in the Liawan Sub-watershed area are very dependent on forests which contain water sources from Mount Sareong for clean water, agriculture and electricity generation purposes. There are many applications of local community knowledge in forest management around the Liawan watershed that need to be published as teaching materials and additional knowledge.
