Anna Juliarti Anna — 2024-01-09

One of the solutions to reduce pressure on the need for agricultural land is to implement an agroforestry system. Agroforestry is an integrated land concept that uses the interaction of agricultural and forestry crops. From the gardens owned by farmers, they can meet their daily needs in the form of agricultural products, firewood, building materials, fruit product, and others. Rokan Hulu Regency, especially Tandun District, has contributes local fruit needs. Fruit are produced from farmer’s gardens from monoculture or agroforestry gardens. The productivity of land owned by farmerscontributes to increase income. Based on research, farmers’ perceptions of the develompent of fruit crops with agroforestry system are categorized as good.the most dominant combination of agroforestry patterns of fruit plants and agricultural crops is the longan and banana with the largest household income being longan fruit as much as IDR 104.160.000 / year

Eni Suhesti — 2024-01-09

Information about the characteristics of honey on the market, including kelulut honey, is not widely known by consumers, even though the characteristics or quality of honey that meet quality standards is very important for consumers. This study aims to 1) test the characteristics of kelulut honey (Heterotrigona itama) from Ghimbo Pomuan Customary Forest, Kampar Regency, 2) compare the characteristic parameters of kelulut honey with standard values in SNI 8664-2018. The procedure for testing the characteristics of honey refers to the Indonesian National Standard (SNI) 8664─2018. Data analysis was carried out descriptively. The results showed that the characteristics of kelulut honey in the study had a distinctive smell and taste of honey, enzyme activity above 0 DN, Hydroxymethylfurfural (HMF) <0.0015 mg/kg, water content 29% w/w, reducing sugar 54.27% w/w, sucrose 1.31% w/w, acidity 201.91 mL NaOH/kg, water-insoluble solids 0.04% w/w, ash 0.30% w/w, lead contamination (Pb) 0.71 mg/w kg, and cadmium (Cd) contamination <0.16 mg/kg. Variable characteristics of kelulut honey that meet the quality incision values of SNI 8664─2018, namely HMF, sucrose, water-insoluble solids, ash, lead metal and cadmium metal contamination. The characteristic variables that do not meet the quality requirements are the activity of enzymes above, reducing sugars, water content, and acidity.

Storage of raw materials affects the production of Cajuput oil as well as the resulting yield. If raw materials are abundant but the production capacity of the cauldron for refining Cajuput leaves and twigs at PMKP Jatimunggul is inadequate, this will cause a decrease in yield because the raw materials are stored for days and the transportation time from BKPH supplier to PMKP Jatimunggul takes a long time. Meanwhile, raw materials are always delivered every day from the supplier KPH. Harvesting Cajuput leaves and twigs that do not comply with the SOP can also reduce the yield of Cajuput oil. Data analysis uses SWOT with questionnaires. Strategies for managing raw materials have a total strength internal factor score of 3.892; weakness of 3,785; opportunity of 3,906; and threats of 3,489. Based on the values obtained, the strategic position for managing Cajuput raw materials and Cajuput oil is located in quadrant I with coordinate values (0.107; 0.417). Strategy Aggressive Strategy (Strengths – Opportunities) to find opportunities from BKPH Subang dan PMKP Jatimunggy by their strengths. Then the company will increase production of raw material from Melaleuca cajuputi leaf-twig.

Model Pendugaan Diameter Pohon Eucalyptus Pellita Clone EP0077AA Berbasis Citra Foto (Unmanned Aerial Vehicle)

Muhammad Vio Mohta — 2024-01-09

The use of remote sensing to estimate the potential of forest stands continues to develop and one of them is using unmanned aerial vehicle (PUTA) technology. But such an important parameter as the diameter of the trunk at chest level cannot be measured from the orthopoto. This research aims to determine a correlation model of aerial crown diameter with trunk diameter at breast height in PUTA-based trees. This research began in October to November l 2022 in the PT area. Arara Abadi, Minas District, Riau region. Aerial measurements of crown diameter were carried out on orthophotos of 36-month-old eucalyptus (Eucalyptus pellita) forest stands, while stem diameter at breast height was carried out terrestrially. The correlation model equations used are Linear, Power, Exponential, Polynomial, and Logarithmic. The research results show that the best model is a non-linear (polynomial) model with a positive linear correlation between stem diameter and aerial crown diameter with the equation y ꞊ 0.2537x – 0.0058x2 – 0.4812 with a coefficient of determination (R2) 0.9047 and a coefficient of correlation (r) of 0.9511. This explains that the variable diameter at chest height influences the diameter of the aerial canopy by 90.47%
