Abstract

Cayenne pepper is a commodity that is quite high in demand in Indonesia. The problem in chili nurseries is to ensure that the plants grow vigor after the transplanting process is carried out. For this reason, it is necessary to provide vitamins to accelerate the adaptation process so that chili plants can grow optimally. To overcome this problem, in this study the application of vitamin B1 (thiamine) was carried out at the beginning of transplanting cayenne pepper seedlings from the nursery. The purpose of this study was to determine the effect of the application of vitamin B1 on cayenne pepper seeds and the best concentration of vitamin B1. This research will be carried out for three months, from early June to the end of August 2023. The research will be conducted in Kelurhan Sidomulyo, Kecamatan Medan Tuntungan, Kota Medan. The research design was a completely randomized design with 1 factor and 3 replications. The treatment factor was the concentration of vitamin B1 with 4 levels. V0: control; V1: 0.5 ml/l vitamin B1; V2: 1 ml/l vitamin B1; and V3: 1.5 ml/l vitamin B1. The results showed that the administration of vitamin B1 (thiamine) during transplanting had an effect on the growth of cayenne pepper seedlings.

Abstract

Limbah kulit pisang dapat menjadi POC mengandung makro dan mkro yang bermanfaat  pertumbuhan dan hasil pada tanaman, dan di aplikasikan kepada tanaman bayam merah. Tujuannya untuk mengetahui  lama fermentasi, kosentrasi, dan interaksinya  POC  Fermentasi kulit buah pisang lilin terhadap pertumbuhan dan hasil  tanaman bayam merah. Metode RAK dengan 2 faktor. Faktor I Lama Fermentasi kulit Pisang, dengan simbol L, taraf L0  (tanpa hari), L1 (1 Minggu), L2 (2 Minggu), L3 (3 Minggu). Faktor II Kosentrasi, simbol K dengan taraf K0 : 0 ml ( kontrol), K1 (15 ml),K2 (25 ml), K3 (35 ml).  Hasil penelitian lama fermentasi  POC terhadap pertumbuhan  tidak beda nyata  kecepatan tumbuh dan jumlah daun,  tinggi tanaman 7 sampai 12 HST dan beda nyata 18 sampai 28 HST,  diameter batang  7, 12 18 HST dan beda nyata  24 sampai 28 HST. Konsentrasi,  tinggi tanaman tidak beda nyata 7 sampai15, dan   beda nyata 18, 14 dan 28 HST, serta diameter batang tidak beda nyata 7, 12, 18 HST dan beda nyata 24, 28. HST. Hasil,    fermentasi 3 minggu (L3) berat kotor 103,33 g/sampel, 868,18 g/plot dan berat bersih 82,19 g/sampel, 666,27 g/plot.  Lama fermentasi 3 minggu (L3) yang terbaik,  konsentrasi pengaruh beda nyata parameter yang diujikan, terbaik menggunakan konsetrasi 35 ml (K3) rata-rata 72,81, konsentrasi 15 ml dengan rata-rata 66,82. Untuk pertumbuhan yang baik. Tidak ada pengaruh  interaksi semua parameter yang diamati adalah dengan menggabungkan yang terbaik  (L3K3).

Abstract

This study aims to modify the design of a coffee bean huller machine to enhance the efficiency and quality of the hulling process. The background of this research lies in the importance of agricultural technology development in improving productivity and the quality of agricultural products, particularly in coffee processing. Existing huller machines have several drawbacks such as low hulling efficiency and damage to the coffee beans produced.  The methodology employed in this research includes literature review, user needs analysis, conceptual modification design, prototype fabrication, and machine performance testing. Various technical aspects such as machine speed, hulling design, and pressure adjustment mechanisms were considered in the modification process. The results of the study show that modifications to the huller machine design can improve the efficiency of the coffee bean hulling process and reduce bean damage. Performance testing of the machine prototype yielded increase in efficiency compared to conventional huller machines. Additionally, the quality of the coffee beans produced also improved, with lower levels of damage. Thus, the modification of the huller machine design has the potential to enhance productivity and quality in the coffee bean hulling process, contributing positively to agricultural technology development in the coffee plantation sector.
