Cocoa seeds are recalcitrant seeds, namely seeds that cannot tolerate drying, and are sensitive to low temperatures and humidity. Naturally, cocoa seeds do not have dormancy, have low shelf life and are sensitive to changes in the storage environment. Therefore, proper handling is required after the seeds arrive at their shipping destination (after the seeds have been stored during shipping). Among them is by providing growth regulator (ZPT) treatment, so that seed vigor can be maintained. Cocoa plants can grow well if planted in media with a composition of organic materials and nutrients needed by the plants. This research aims to look at the interaction of natural growth hormones and planting media on cocoa seeds which experience a decrease in quality on the growth of cocoa seedlings. This research used a split plot design with a RAL pattern consisting of a main plot which was a combination of planting media and sub plots which were natural growth hormones, each treatment was repeated 3 times. Each experimental unit consisted of 3 seed samples, so that 90 seeds were obtained. The research results showed that there was no interaction between the use of natural growth hormones and the composition of the planting medium on the parameters of seed water content, vigor index, germination power, growth speed, seed height, number of leaves, leaf area and root volume, as well as seed dry weight. The best hormonal treatment for the parameters of leaf area, root volume and dry weight of seedlings is a hormone from tomato extract. The best planting media composition is alluvial topsoil + chicken manure + husk charcoal (1 : 1 : 1).

Tanah aluvial dalam bidang pertanian memiliki kekurangan seperti nilai pH yang rendah, struktur tanah yang jelek, kapasitas tukar kation dan permeabilitas tanah yang rendah. Upaya mengatasi kendala pada tanah aluvial tersebut salah satunya dapat dilakukan dengan penerapan ameliorasi. Bahan-bahan yang dapat digunakan sebagai sumber ameliorasi yaitu biochar tandan kosong kelapa sawit (TKKS) dan fly ash batu bara. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian biochar TKKS dan fly ash batu bara terhadap sifat kimia tanah aluvial. Metode penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) faktorial dengan 3 ulangan yang terdiri dari 2 faktor yakni penggunaan fly ash (a0 =tanpa fly ash, a1=fly ash 25% dan a3=fly ash 50%) dan pemberian biochar (b0=tanpa biochar, b1= biochar 5% dan b2= biochar 10%). Hasil penelitian menunjukkan bahwa terdapat interaksi antara perlakuan fly ash dan pemberian biochar. Interaksi fly ash 50% dan biochar TKKS 10% memberikan perubahan sifat kimia tanah yang paling baik yakni dapat meningkatkan pH tanah (6,76), meningkatkan kandungan P2O5 (38,29 mg/kg), meningkatkan KTK tanah (23,65 cmol/kg) dan menurunkan kandungan Cu (0,21%). Penambahan ameliorasi biochar TKKS dan fly ash batubara terbukti dapat memperbaiki kualitas tanah aluvial sehingga dapat digunakan untuk mendukung pertumbuhan tanaman secara optimal.

The productivity of rubber plants in Indonesia is relatively low, so efforts to increase productivity need to be made, one of which is by improving cultivation technology, the limitation of nutrients in the soil of former gold mines is overcome by providing vegetable waste compost. Vegetable waste compost has a C-organic content of 28.89%, N 1.57%, P 1.39%, K 0.69%. This study aims to determine the effect of vegetable waste compost on the growth of rubber seedlings on the soil of former gold mining land. The research was conducted at the Sukaharja Experiment Garden, Gg. Pandan, from April to July 2024. The study used a non-factorial Complete Random Design (RAL) consisting of 5 groups and 5 replicates, there were 25 experimental units, each experiment consisted of 3 samples so that the total number of samples was 75 samples. The parameters observed were the height of the seedlings, the diameter of the stems, the number of umbrellas, and the dry weight of the seedlings. The data is statistically analyzed with Analysis of Variance (ANOVA), if obtained has a real effect, then the Duncan Multi Range Test (DMRT) is continued at the level of 5%. The results of the fingerprint showed that the treatment of vegetable waste composting had a real influence on the variables of seedling height, stem diameter, number of umbrellas, and root volume. The results of the DMRT test at 5% level show that treatment with a dose of vegetable waste compost of 640 g/polybag is able to provide good growth for the growth of rubber seedlings.

Golden apple snails are pests and can be processed into liquid organic fertilizer due to their ability to improve soil quality and provide nutrients to plants. Golden apple snails contain compounds that can be used as plant nutrients, including the amino acid tryptophan, phosphorus (P), and calcium (Ca), making them suitable raw materials for liquid organic fertilizer. This study aimed to determine the effect and optimal dosage of golden apple snail POC on rubber seedling growth in peat media. The study was conducted from March to June 2024 at the Tempurukan Village experimental garden. The study used a non-factorial Completely Randomized Design (CRD) with 5 treatments and 4 replications. Each treatment consisted of 4 plants, resulting in 80 experimental units. Observation parameters included plant height (cm), number of umbrellas (stalks), stem diameter (cm), root length (cm), and plant dry weight (g). Data analysis used ANOVA and a 5% DMRT follow-up test using the DSAASTAT application. The results showed that golden apple snail POC application significantly affected plant height, stem diameter, number of umbrellas, root length, and dry weight of rubber plants. A dose of 40 golden apple snail POC per plant was the best treatment for increasing rubber seedling growth, with an average seedling height of 63.12 cm, stem diameter of 0.44 cm, number of parasols of 3, root length of 54.50 cm, and plant dry weight of 10.14 g.
