Abstract

Weeds are undesired plants to grow so weed management is expected to overcome losses caused by weeds. One way to manage weeds using herbicides is the chemicals used for weed management in plants. This study aims to determine the influence of weed management using herbicides on corn yields. The research was conducted in Sekoci Village, Besitang District, Langkat Regency, North Sumatra in April-June 2021. This study used a non-factorial Randomized Block Design (RBD), with 4 treatments and 3 replications, namely contact, systemic, weeding and weeds without management. The results showed that herbicide management significantly affected 100 seed weight, cob weight per plot and seed weight per plot, but had no significant effect on weed without management. It indicates that the treatment of weed management using herbicides affects plant growth and yield. Weed management for farmers is very important to prevent competition for nutrients between weeds and corn.

Abstract

Lettuce is a popular leafy vegetable among the community. The expansion and potential of lettuce cultivation require efficient growing techniques. The production of plants using a hydroponic system is closely linked to the availability of nutrient solutions. This study aimed to examine how various fertilizer formulations affect the macronutrient (P, K, Ca, Mg, S) and micronutrient (Fe, Zn, Mn, Cu, B) content of hydroponically grown lettuce plants. A completely randomized design (CRD) was employed, and the Wet Digestion Method was used to prepare dry plant samples by breaking them down with a mixture of strong acids and heat. Nutrient concentrations were then analyzed using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). Statistical analysis of the nutrient data was performed using ANOVA to identify significant differences between treatments. The results indicated that the AB fertilizer and the O38 treatment were the most effective in increasing the majority of nutrients in the plants. Fertilizers with the highest phosphorus content were observed in the AB and O38 treatments, while the highest potassium content was found in the AB and O39 treatments. The highest calcium (Ca) and magnesium (Mg) levels were also recorded in the O38 treatment, highlighting the formulation’s efficiency in supplying macronutrients. Regarding micronutrients, the highest iron (Fe) content was detected in the O37 treatment, whereas the highest zinc (Zn), copper (Cu), and boron (B) contents were found in the AB treatment. This study demonstrated the superiority of the AB fertilizer, which performed best and most consistently. However, the O38 formulation shows potential as a future alternative to commercial AB fertilizers, pending further improvements.

Abstract

Kajian ini bertujuan untuk mensintesis literatur mengenai posisi, pengolahan, standardisasi mutu, dan potensi ekonomi simplisia nabati dalam sektor pertanian di Indonesia. Kajian literatur naratif dilakukan terhadap sepuluh sumber utama yang terdiri atas artikel penelitian empiris, laporan pengabdian kepada masyarakat, dan pedoman teknis nasional yang terbit antara tahun 2011 hingga 2025. Hasil kajian menunjukkan bahwa simplisia berfungsi sebagai komoditas pertanian bernilai tambah yang menghubungkan kegiatan budi daya di lahan dengan industri obat tradisional, dengan tanaman rimpang famili Zingiberaceae mendominasi baik pasokan hasil budi daya maupun perdagangan di pasar tradisional. Mutu produk ditentukan oleh rangkaian terpadu antara praktik budi daya yang baik, tahapan penanganan pascapanen (sortasi, pengerikan, perajangan, pengeringan di bawah suhu 60°C, penggilingan, dan penyimpanan), serta parameter mutu terstandar seperti kadar air, yang menurut beberapa pengujian gravimetri terbukti dapat dipertahankan di bawah ambang batas 10% sesuai persyaratan farmakope nasional. Pengolahan simplisia berbasis masyarakat dan pemasaran digital, seperti produksi serbuk kunyit, terbukti mampu meningkatkan pendapatan rumah tangga, meskipun ketergantungan musim dan pasokan dari tumbuhan liar yang sebagian berstatus konservasi masih menjadi kendala utama. Kajian ini menyimpulkan bahwa penguatan sumber bahan baku berbasis budi daya, standardisasi pascapanen, dan akses pasar menjadi kunci untuk memposisikan simplisia sebagai komoditas pertanian yang berkelanjutan.
