    PENINGKATAN DAYA KECAMBAH KAPULAGA LOKAL DENGAN SKARIFIKASI ASAM SULFAT
    (Elfitra, 2023-01) Basri, Intan; Sujarwati, Sujarwati
    Difficulty on germination of local cardamom (Amomum cardamomum Willd) is caused by the hard seed coat leading to dormant period. Breaking dormancy in hard seed coats can be done by chemical scarification, one of which is using sulfuric acid. This study aimed to determine the effect of sulfuric acid concentration and soaking time on local cardamom germination and to determine the effective concentration of sulfuric acid and soaking time to increase the germination of local cardamom. This study used a factorial completely randomized design with two factors i.e. concentration of sulfate acid with 6 levels (0%, 60%, 70%, 80%, 90% and 100%) and soaking time with 4 levels (5 minute, 10 minute, 15 minute and 20 minutes). Variables observed were germination percentage, germination time and vigor index. The results showed that the combination of 60% sulfuric acid treatment for 15 minutes resulted in the highest germination percentage of 62.50% with a germination time of 29.10 days and vigor index of 1.36 seeds germinated/week.

    STRUKTUR ANATOMI PERBANDINGAN AKAR BIBIT KELAPA SAWIT (Elaeis Guineensis Jacq.) DENGAN CEKAMAN PENGGENANGAN DI LAHAN GAMBUT DAN TANPA CEKAMAN PENGGENANGAN
    (2020-11) Septiani, Andi Astri; Sujarwati, Sujarwati
    The palm oil plant (Elaeis guineensis Jacq.) has survival in flooding conditions on peatlands. However, the connection between oil palm resistance and responses to the anatomical structure of the root was still unknown. Changes in root anatomy under flooding conditions can be observed by comparing the root anatomical structure which experienced flooding stress to root tissue structures that do not experience flooding stress. The purpose of this research was to observe the comparison of the root anatomical structure of oil palm which experienced flooding stress on peatlands and without flooding stress. Samples of the palm oil plant roots were treated with flooding experience for 30, 50, 70 and 90 days. Root anatomical preparations used paraffin method. The results showed that the root anatomical structure of the palm oil plant seedlings consisted of epidermal, hypodermal, sclerenchyma, cortex, endodermis, and stele tissue, in which there were vascular bundles and pith. Anatomical structure of the roots of palm oil plant seedlings showed that experience flooding in peatlands could not be observed, because the anatomical conditions of the roots were shrinking and the root cortex tissue was damaged, which were caused by the delay in fixation of the root samples after dismantling the palm oil plant seedlings, so that the samples underwent dehydration or dryness.

    TEKNIK BUDIDAYA MICROGREENS DARI BIJI PEPAYA (Carica papaya L. var. Callina) MENGGUNAKAN MEDIA KOMPOS
    (Elfitra, 2023-05) Wulandari, Retno Ayu; Sujarwati, Sujarwati
    Microgreens contain higher level of micronutrients and bioactive compounds compared to mature plants. Papaya fruit is widely consumed, as a result a lot of papaya seed waste is not utilized. Papaya seeds have a complex nutritional content, therefore they are suitable to be cultivated as microgreens. This study aimed to cultivate microgreens from papaya seeds of Callina cultivar under compost media. This study involved preparation of planting media, seed preparation, seedling, maintenance and harvesting of papaya seed microgreens. Data were analyzed with a qualitative descriptive method. Results showed that papaya seed microgreens could grow well on compost media, although some parts of seedlings were contaminated by fungi. In addition, growth of microgreens were not at uniform rate. However, these problem could be overcome immediately. This study suggested that it is necessary to carry out further research with several combinations of planting media to find the best response from the growth of microgreens.
