Gamal (Glericida manuculata) is used by farmers as a coffee shade plant and as animal feed, kirinyuh (Eupatorium odoratum) grows as a weed. Both plants have allelopathic substances that inhibit the growth of cultivated plants. Gamal plants produce allelopathic substances from the saponin and polyphenol groups. Kirinyuh plant produces allelopathic substances such as flavonoids, alkaloids, tannins, and limonene. The aim of the research was to determine the effect of allelopathy of gamal and kirinyuh plant species on mung bean germination. The method used extracts of gamal and kirinyuh plants with concentrations of 46%, 36%, and 26%. The results showed the effect of allelopathic plant species on the growth of mung bean epicotyl, extract treatment of gamal plant on the 10th day of longest epicotyl length was 36% concentration, which was 29.7 mm, the shortest was 46% concentration of 6.7 mm. Kirinyuh plant extract on day 10 of the shortest epicotyl growth with 46% extract was 16 mm, while the longest epicotyl growth was 36% at 21mm. Radicle length on day 10 for the shortest gamal plant extract was treated with a concentration of 46% at 17 mm, while the shortest kirinyuh plant extract was a concentration of 26% at 24 mm. The effect of allelopathic plant species on the percentage of mung bean germination for the 100% gamal extract treatment, namely the extract with a concentration of 36% and 26%, while the 46% extract had 93.33% germination. Kirinyuh plant extract had the highest germination percentage at 36% concentration treatment.
Indonesia occupies the 4th position of the 5 main coffee producing countries in the world. Coffee plants are a high foreign exchange earner in the Indonesian economy. Data from the Central Statistics Agency (BPS) show that Indonesia's coffee production in 2021 was the highest in the last decade, reaching 774.6 tonnes. This number increased by 2.75% from the previous year of 753.9 thousand tonnes. Coffee seed germination takes a long time due to seed dormancy. Coffee growth can be optimal with the provision of growth regulators. Good planting media can produce quality coffee seeds, because in good media there are nutrients needed by plants. The research was conducted at the Jember State Polytechnic Soil Wire House Laboratory in February-May 2022. Data were analyzed using Factorial RAK with a 5% BNJ follow-up test. The results showed that the combination treatment of planting media and natural ZPT concentrations had a significant effect on the generative growth of Robusta coffee (Coffea canephora L) including germination percentage, root length, height and seedling diameter.
Penggunaan pupuk anorganik pada lahan tebu yang tidak berimbang dan pemberian secara terus menerus dapat menurunkan kesuburan dan produktivitas tanah. Pemberian pupuk anorganik secara terus menerus dapat menekan aktivitas mikroorganisme tanah, menurunkan kandungan bahan organik dan dapat merubah tekstur tanah menjadi padat. PG Pradjekan sebagai Mitra dalam Pengabdian pada Masyarakat menjadi salah satu produsen gula yang menghasilkan limbah hasil pengolahan tebu dalam bentuk molase dan blotong yang tidak dimanfaatkan dengan optimal. Upaya dalam meningkatkan kesuburan dan produktivitas tanah lahan tebu dan menambah nilai manfaat dari limbah hasil pengolahan tebu Tim Pengabdian pada Masyarakat dilakukan dengan memberikan penyuluhan dan pelatihan perbanyakan dekomposer untuk pupuk organik blotong. Hasil kegiatan penyuluhan dan pelatihan di PG Pradjekan memberikan manfaat kepada peserta pelatihan untuk menambah wawasan dan pemahaman akan pentingnya penggunaan pupuk organik pada tanah, meningkatkan keterampilan dalam pembuatan dekomposer dan pupuk organik bloton serta memanfaatkan limbah organik menjadi nilai tambah
Jember is known as the region that produces the source of coconut in abundant yet it is not utilized optimally in processing. The research was carried out in May to November 2020 at Jember: 1) in the lowland Wuluhan and Puger subdistrict with a height of 10-100 m above sea level; 2) in Medium region in Arjasa and Silo Subdistrict with an altitude of 100-350 m above sea level and 3) High region in Sumberjambe and Panti subdistrict, with an altitude 400 m above sea level. The measurement of the fruit was analyzed by using a ruler and digital weighing, involved 1) the weight of coconut, 2) fiber of the coconut, 3) water, 4) shell, 5) flesh coconut, and 6) Copra. Data of research are by description. Physical characteristics include the weight of the coconut fruit, the weight of coconut water, the weight of coconut flesh, the weight of the coconut shell, the weight of the copra and the thickness of the coconut flesh. The coconut showed optimally physical characteristics in the medium region (100-350 m above sea level).
Virgin coconut oil (VCO) merupakan produk olahan dari daging kelapa yang berupa cairan berwarna jernih, tidak berasa, dengan bau khas kelapa. Tujuan dari penelitian ini untuk mengetahui pengaruh lama penyimpanan buah kelapa terhadap mutu VCO yang dihasilkan. Terdapat 5 perlakuan pada penelitian ini yaitu P0, P5, P10, P15, dan P20 dengan ulangan 6 kali dan dianalisa menggunakan rancangan acak lengkap non factorial dan uji BNJ. Perlakuan terbaik yaitu P20 (lama penyimpanan 20 hari) rendemen 15,65%; kadar air 0,2%; kadar asam lemak bebas 0,05%; viskositas 6,692 Pa.s.
