Tanaman tomat termasuk ke dalam tipe tanaman yang dapat tumbuh pada berbagai tipe tanah. Produksi tomat di Provinsi Riau masih rendah yang dapat disebabkan oleh jenis tanah PMK yang memiliki kandungan nutrisi dan unsur hara yang rendah. Untuk memperbaiki sifat fisik, kimia dan biologi tanah PMK dapat diberikan bahan organik salah satunya yaitu asam humat dan dapat dikombinasikan dengan pupuk KCl sebagai penyedia unsur hara bagi tanaman. Tujuan penelitian ini adalah untuk mengetahui pengaruh dan mendapatkan dosis terbaik pada interaksi pemberian asam humat dan pemberian pupuk KCl terhadap pertumbuhan dan produksi tanaman tomat ceri (Solanum lycopersicum var. cerasiforme) pada tanah PMK. Penelitian ini dilaksanakan secara eksperimen dengan menggunakan Rancangan Acak Lengkap (RAL) faktorial, yang terdiri dari dua faktor yaitu A (Asam humat), terdiri dari 3 taraf yaitu A0 (0g/L), A1 (0,15 g/L) dan A2 (0,30 g/L), dan faktor K pupuk (KCl) terdiri dari 3 taraf yaitu K0 (0 g/polybag), K1 (6 g/polybag) dan K2 (12 g/polybag), masing-masing terdiri dari 3 ulangan, Jumlah satuan percobaan sebanyak 27 plot, setiap plot terdiri dari 4 tanaman dan 2 tanaman sebagai sampel. Berdasarkan hasil penelitian Interaksi pemberian asam humat dan pupuk KCl berpengaruh nyata terhadap semua parameter pengamatan yaitu tinggi tanaman, diameter batang, jumlah buah/tanaman, jumlah cabang produktif dan bobot buah/tanaman. Dosis terbaik untuk asam humat adalah perlakuan A2 0,30g/L dan dosis terbaik untuk pupuk KCl adalah 12 g/polybag, dosis terbaik untuk interaksi asam humat dan pupuk KCl adalah A2K2 yaitu asam humat 0,30 g/L dan pupuk KCl 12 g/polybag.

Bananas is a tropical fruit that is quite popular because of their freshness and can be consumed directly or processed as a snack. Banana cultivation is increasing along with the increasing demand for bananas in the market. As a climacteric fruit, bananas ripen quickly so they spoil quickly and have a low shelf life. To extend shelf life, ethylene gas in the surrounding environment must be controlled, for example, using active packaging made from ethylene gas absorbent. Several studies used activated carbon from coconut shells, chitosan, and teak leaves as ethylene absorbent material to extend the shelf life of climacteric fruit (e.g., guava, avocado, and tomato) with various types of packaging and doses of absorbent materials. This study examines the shelf life of bananas packaged in active packaging that absorbs ethylene using activated charcoal from coconut shells. As a result, activated charcoal with the addition of KMnO4 to absorb ethylene could extend the shelf life of bananas for 6 days longer than without activated charcoal.

Thermoplastic starch (TPS) is a biofilm made from starch and cellulose. The advantage of thermoplastic starch is easily degraded. TPS has weaknesses in high water affinity and low mechanical properties, so it is necessary to add polyvinyl alcohol (PVA) in making TPS packaging. The mechanical properties of TPS-PVA can be further improved by modifying it into a composite with coconut fiber cellulose. This research was purposed to produces a film containing cellulose from coconut fiber as a reinforcing material for film composites as well as to evaluate the biodegradation properties of the resulting film. It is known that the addition of 5% w/v coconut cellulose fiber is the formulation with the best yield when compared with the 1% and 3% w/v formulations. Applying TPS film to chilies can increase the shelf life of chilies. As a product that spoils quickly, one of the efforts made to maintain the quality of chilies is to use packaging made from TPS. Storing chilies at different temperature conditions using TPS-PVA film packaging with the addition of 5% w/v coconut fiber cellulose was able to maintain the shelf life and quality of chilies for 19 days at cold temperatures.

The shallot plant is an important vegetable commodity because it contains high nutrition, raw material for medicines, and as a complement to cooking spices, and has many vitamins and acts as an enzyme activator in the body. Shallot production, especially in Riau Province, is still not sufficient for the people's needs. The low production yield is due to low soil fertility and sub-optimal cultivation methods. For this reason, efforts are needed to increase shallot yields in Riau Province. In order for the land to be productive, it is necessary to make efforts to improve it by adding ameliorants, which are materials that can increase soil fertility by improving the physical, chemical and biological conditions of the soil. The purpose of this study was to determine the effect and obtain the best dose of Humic Acid, NPK Mutiara 16:16:16 fertilizer, and its interaction on the growth and production of shallots. This research was carried out experimentally using a factorial Completely Randomized Design (CRD), which consisted of two factors, namely H (Humic Acid) which consisted of 3 levels, and factor N (NPK fertilizer) which consisted of 3 levels, and each of them had 3 repetitions, the number of experimental units is 27 plots, each plot consists of 3 plants and 2 plants as samples, so the number of plants is 27x3 = 81 plants. The parameters observed were as follows: "Plant Height" (cm), "Number of Leaves" (strands), "Number of tubers (cm2), Diameter of tubers (cm), Number of tubers (fruits) and Weight of tubers (grams). And the interaction of humic acid and NPK fertilizer with doses of H2N2 (giving 2 g/polybag of humic acid and 20 g/polybag of NPK) gives the best results.

This study aims to determine the effect and obtain the best dose of ZPT Growtone on the growth of oil palm seedlings (Elaesis guineensis Jacq) in pre-nursery. This research was carried out experimentally using a completely randomized design (CRD) with 5 treatments and 4 replications namely G0 (without treatment), G1 (ZPT Growtone 2 gr/l), G2 (ZPT Growtone 4 gr/l), G3 (ZPT Growtone 6 gr/l), G4 (ZPT Growtone 6 gr/l). The number of experimental units was 20 plots consisting of 16 plants and 4 plants as samples, the parameters observed were plant height, number of leaves, stem diameter and leaf area. The results of this study were that the administration of ZPT Growtone had a very significant effect on the growth of oil palm seedlings on the parameters of plant height, number of leaves, stem diameter and leaf area. The best growth of oil palm seedlings was found in the G3 treatment with a concentration of 6 g/l.
