ABSTRAK
Penelitian pengaruh kompos kulit kopi (Coffea arabica L.) dan Trichoderma sp.
terhadap pertumbuhan tanaman cabai rawit (Capsicum frutescens L.) telah
dilakukan. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk
kompos kulit buah kopi (Coffea arabica L.) yang ditambahkan Trichoderma sp.
terhadap pertumbuhan tanaman cabai rawit (Capsicum frutescens L.) dan
mengetahui dosis Trichoderma sp. yang optimal terhadap pertumbuhan tanaman
cabai rawit. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL), dengan
5 perlakuan dan 5 ulangan. Perlakuan terdiri dari kontrol (P0), pemberian kompos
kulit buah kopi + Trichoderma sp. 10 gram (P1), pemberian kompos kulit buah kopi
+ Trichoderma sp. 20 g (P2), pemberian kompos kulit buah kopi + Trichoderma sp.
30 g (P3), pemberian kompos kulit buah kopi + Trichoderma sp. 40 g (P4). Parameter
yang diamati adalah tinggi tanaman, panjang daun, lebar daun, jumlah daun dan
diameter batang. Data hasil penelitian dianalisis menggunakan Analysis of varians
(ANOVA) menggunakan SPSS 26 dengan tingkat signifikan 5% dan uji lanjut
menggunakan metode DUNCAN. Hasil penelitian menunjukkan bahwa pemberian
kompos kulit kopi dan Trichoderma sp. memberikan pengaruh yang nyata terhadap
pertumbuhan tinggi tanaman cabai, banyak daun, panjang daun, lebar daun dan
diameter batang tanaman cabai rawit. Perlakuan pemberian kompos kulit buah kopi +
Trichoderma sp. 20 g (P2) memberikan hasil yang paling efektif dalam pertambahan
tinggi tanaman, jumlah daun, panjang daun, dan diameter batang.
Kata kunci: cabai rawit, kompos, kulit kopi, Trichoderma sp.

ABSTRACT Research on the effect of coffee peel compost (Coffea arabica L.) and Trichoderma sp. on the growth of cayenne pepper plants (Capsicum frutescens L.) has been conducted. It is intended to determine the impact of applying coffee peel compost (Coffea arabica L.) supplemented with Trichoderma sp. on the growth of cayenne pepper plants (Capsicum frutescens L.) and to identified the optimal dose of Trichoderma sp. for enhancing the growth of cayenne pepper plants. This study used a Completely Randomized Design (RAL) with 5 treatments and 5 replications. The treatments consisted of a control (P0), coffee peel compost + Trichoderma sp. 10 grams (P1), coffee peel compost + Trichoderma sp. 20 grams (P2), coffee peel compost + Trichoderma sp. 30 grams (P3), and coffee peel compost + Trichoderma sp. 40 grams (P4). The parameters observed were plant height, leaf length, leaf width, number of leaves, and stem diameter. The data were analyzed using Analysis of Variance (ANOVA) with SPSS 26 at a significance level of 5% and with the advance analysis using DUNCAN method. The results showed that the application of coffee peel compost and Trichoderma sp. had a significant effect on the growth of plant height, number of leaves, leaf length, leaf width, and stem diameter of the cayenne pepper plants. The treatment of coffee peel compost + Trichoderma sp. 20 grams (P2) was the most effective in increasing plant height, number of leaves, leaf length, and stem diameter.
