The growth of avocado and its yield can be achieved by fulfilling requirements for the growth and maintenance of the plant well. Planting on dry land requires the addition of organic fertilizer and optimal water requirements to increase organic matter content and plant fertility. This research aims to obtain the optimal dosage of compost and watering intervals for the growth of avocado (Persea americana). The research was carried out in the Greenhouse Faculty of Agriculture, Universitas Sumatera Utara. This research used a factorial completely randomized design (F-CRD) with the addition of compost fertilizer doses (K0:0 kg, K1:0.5kg. K2: 1 kg. K3: 1.5 kg and K4: 2 kg) and watering intervals (A1: once a day. A2: once every three days. A3: once every five days and A4: once every seven days) with parameters of observation of height, diameter, top fresh weight, root fresh weight, top dry weight and root dry weight. The results showed that the interaction of compost and watering intervals significantly affected the height and diameter increase, root fresh weight, and root dry weight of avocado plants. The interaction of giving 1.5 kg of compost and watering intervals every day had the best effect on the growth and quality of avocado seedlings","PeriodicalId":479486,"journal":{"name":"Global Forest Journal","volume":"11 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140482435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method used in this research is a qualitative approach. Data was obtained through in-depth interviews involving key informants who were selected and determined using snowball sampling and analyzed using SWOT analysis of Strengths, Weaknesses, Opportunities and Threats, which includes Natural Resources and Human Resources. The results of this research show that the total value of the influence of internal strategies has a value difference of 0.32. Likewise, the external value has a difference of 0.11. Then, combining the two values of the difference between strengths and weaknesses and opportunities against threats, a coordinate point is obtained, namely the coordinate point (0.32; 0.11). The strategy that must be implemented in Sumber Nadi Village, Ketapang, is to support aggressive growth policies (growth-oriented strategy).

This research aims to determine the processing of rubber latex in agroforestry carried out by the community in Menggala Mas Village, Lampung Province, Indonesia. This research approach is qualitative. Data was obtained by observation, in-depth interviews, and documentation studies. Then, the data was processed by making data transcripts, coding, categorizing, drawing temporary conclusions, triangulating, and drawing conclusions so that the results obtained could be analyzed to determine the data processing. Local communities carry out rubber in agroforestry. The research results showed that three applications of agroforestry planting patterns were found, namely alley cropping (alley pattern), Trees along border (fence pattern), and random mixture (random pattern). The dominant combination in alley cropping is rubber-pulai, and rubber-mentru-afrika wood. The dominant combinations in Trees along the border are rubber-acacia, rubber-jackfruit-cempedak, rubber-petai-teak. The dominant combinations in the random mixture are rubber-jengkol, rubber-petai-jengkol-acacia, rubber-jackfruit-cempedak, rubber-pulai-noni-jengkol, rubber-banana-gadung-sungkai. The rubber latex processing process in agroforestry is carried out traditionally, starting from the tapping process, sap acidification, sap harvesting (napeu), sap separation, and sales and harvesting of agroforestry crops. The community's local knowledge has been passed down from their parents to reduce the costs of processing rubber latex from expensive materials so that the community can gain more profits. This has been proven if local communities can manage their land well, which can become a long-term source of livelihood. The government needs to assist with strategies for processing rubber latex as well as managing rubber agroforestry land to increase farmers' knowledge and harvest yields","PeriodicalId":479486,"journal":{"name":"Global Forest Journal","volume":"50 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140480417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this research was to investigate the floristic composition and carbon stock of R. apiculata in the Pasar Rawa Village restoration area, Langkat Regency, North Sumatra Province. This study employed the vegetation analysis approach and carbon estimates based on diameter breast height (DBH) and total vegetation height. The study's findings indicate low floristic diversity in the research area. At the seedling stages, the greatest IVI (113.68%) was discovered in Achanthus ilicifolius, and the only species found in the sapling stage with an IVI value of 200% was R. apiculata. The study of diversity indices revealed very low values at the seedling stage (H'= 0.806) and no diversity at the sapling stage. The total carbon stored estimation in R. apiculata stands relatively low, at 8.56 tonnes/ha.
