“…Cardamom grows and develops in the Asian continent, such as Indonesia, Sri Lanka, Nepal, Tanzania, Guatemala, and India (Garg et al, 2016;Abu-Taweel et al, 2018). Qonita et al (2018) reported that traditionally Java cardamom is often used as a spice in certain dishes, herbal medicines, health drinks, and aromatherapy. The use of herbal medicine and cooking spices from Java cardamom is related to the secondary metabolite content in the essential oil of cardamom (Silalahi, 2017).…”

Java cardamom is an herbal medicinal plant known as the "queen of spices." This research aims to determine the influence of shading and nitrogen fertilizer dose on the total phenolics, flavonoids, and antioxidant activity of Java cardamom stems and rhizomes. The study employed a split-plot design with two factors: the level of shading (0, 25, 50, and 75%) as the main plot and the dosage of nitrogen (N) fertilizer (0, 0.9, and 1.36 g polybag-1) as the subplots. Twelve months after planting, the rhizome and stem dried powder were extracted using the sonication-maceration technique with ethanol as the solvent. The 75% shading affected the more outstanding production of total phenolics (1.65 ± 0.59 mg GAE g-1 DW), DPPH antioxidant (4.95 ± 0.50 µmol TEAC g-1 DW), and FRAP antioxidant (8.94 ± 2.56 µmol TEAC g-1 DW) activities of the rhizomes cultivated with 0 g/polybag N in comparison to the stems of the plants. Contrary to phenolics and antioxidant activities, total flavonoids cultivated at 0% shading with 1.36 g polybag-1 N of the stems increased concentration than the rhizomes. The results indicated that the 75% shading affected the Java cardamom rhizome's phenolic content and antioxidant activities.

“…Kapulaga merupakan salah satu golongan tanaman rempah (Qonita et al, 2018) yang buahnya mempunyai nilai ekonomis tinggi (Murugan et al,2022) dan berprospek pasar yang baik (Siarudin et al, 2021) karena diminati oleh banyak konsumen, baik konsumen dalam negeri maupun konsumen internasional (Direktorat Sayuran dan Tanaman Obat, 2019). Buah kapulaga selain dapat dimanfaatkan untuk bumbu masak dan bahan kosmetik (Nurzaman et al, 2020), juga dapat dimanfaatkan sebagai bahan obat alamiah yang diyakini oleh masyarakat memiliki banyak manfaat atau kegunaan untuk pengobatan tradisional (Janani, 2019;Mohammad et al, 2022) misalnya untuk penyegar napas, anti radang, dan menyembuhkan batuk (Mohammad et al, 2022).…”

Cardamom can live under the shade of stand, but require adequate shade for optimum growth. Therefore, this research aims to determine the relationship between the percentage of solar radiation under the shade of stand on the growth of cardamom, and to estimate the percentage of solar radiation that affects the optimum growth of cardamom. The research was conducted in 5 farmer-cultivated areas planted with cardamom in Tahura Wan Abdul Rachman. In each farmer's arable area, 3 plots of 5 m x 5 m were made, which were placed randomly to observe the growth of cardamom. The data collected includes: growth of cardamom, tree species that make up forest garden stands, solar radiation under the shade or in the open, air temperature, and humidity. The data were analyzed by quadratic regression at the 5% significance level. The results showed that the difference in the shade of stands had a significant effect on the growth of cardamom. All cardamom growth variables were significantly correlated with the percentage of solar radiation under the shade of stand. The optimal number of stems is 49.5 stems at a percentage of 63% solar radiation. The optimal plant height of 146.74 cm at a percentage of 67% solar radiation. The optimal number of leaves per clump is 235.296 leaves at 60% solar radiation percentage. The number of flower bunches per cluster is optimal as much as 23.4 bunches at the percentage of solar radiation 60.5 %. The optimal number of fruits per fruit bunch is 8.7 fruits at the percentage of solar radiation 56 %. Thus, cardamom plants will grow optimally under the shade of the standing canopy with a percentage of solar radiation from 56% to 67%.Keywords: cardamom; forest gardens; growth; shade; standABSTRAKHubungan Persentase Radiasi Matahari di Bawah Naungan Tajuk Tegakan dengan Pertumbuhan KapulagaKapulaga dapat hidup di bawah naungan tegakan, akan tetapi membutuhkan naungan yang memadai untuk pertumbuhan optimal. Oleh karena itu, penelitian bertujuan untuk mengetahui hubungan persentase radiasi matahari di bawah naungan tegakan kebun hutan dengan pertumbuhan kapulaga, serta mengestimasi persentase radiasi matahari yang berpengaruh terhadap pertumbuhan optimum kapulaga. Penelitian dilakukan di 5 areal garapan petani yang ditanami kapulaga dalam Tahura Wan Abdul Rachman. Data yang dihimpun meliputi: pertumbuhan kapulaga, jenis pohon penyusun tegakan kebun hutan, radiasi matahari di bawah naungan maupun di tempat terbuka, temperatur udara, dan kelembapan udara. Data dianalisis regresi kuadratik pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa perbedaan naungan tegakan kebun hutan berpengaruh nyata terhadap pertumbuhan kapulaga. Semua variabel pertumbuhan kapulaga berhubungan nyata secara kuadratik dengan persentase radiasi matahari di bawah naungan tegakan. Jumlah batang per rumpun yang optimal sebanyak 49,5 pada persentase radiasi matahari 63%. Tinggi kapulaga yang optimal 146,74 cm pada persentase radiasi matahari 67%. Jumlah daun per rumpun yang optimal sebanyak 235,296 helai pada persentase radiasi matahari 60%. Jumlah tandan bunga per rumpun yang optimal sebanyak 23,4 pada persentase radiasi matahari 60,5%. Jumlah buah per tandan yang optimal sebanyak 8,7 pada persentase radiasi matahari 56%. Dengan demikian, kapulaga akan tumbuh secara optimal di bawah naungan tegakan yang persentase radiasi matahari sebesar 56% hingga 67%.Kata kunci: kapulaga; kebun hutan; naungan; pertumbuhan; tegakan
