UJI APLIKASI MULSA ORGANIK LEMBARAN DARI LIMBAH TANDAN KOSONG KELAPA SAWIT DAN KULIT SINGKONG SEBAGAI UPAYA PENINGKATAN HASIL TANAMAN BAWANG MERAH (Allium ascalonicum L).

Shallots (Allium ascalonicum L.) are an important horticultural commodity in Indonesia,
widely cultivated by farmers due to high demand. One way to increase production and support
agricultural sustainability is to utilize agricultural waste as the base material for organic sheet mulch.
This study aims to examine the effect of the application of organic mulch sheets made from empty
oil palm bunches (EFB) and cassava peels (CFB) waste on the growth and yield of shallots. The
research was conducted on the Rusunawa Land of Muhammadiyah University of Malang with a
simple Randomized Block Design (RAK), using 8 mulch composition treatments of Oil Palm Empty
Fruit Bunches: Cassava Husk (TKKS: KS) including plastic mulch control, and each treatment was
repeated 3 times. The parameters observed included the number of leaves, plant height, wet weight,
dry weight, and number of tubers, which were analyzed using ANOVA and the 5% Honestly
Significant Difference (HSD) test. The results of the study showed that organic sheet mulch based
on a combination of Empty Oil Palm Fruit Bunches (EFB) and Cassava Peel (CF) had a positive and
significant effect on the growth and yield of shallots compared to plastic mulch, especially in a
balanced composition of 50:50 which provided the highest leaf growth. Organic mulch from a
combination of Empty Oil Palm Fruit Bunches (EFB) and Cassava Peels (CFB) as well as plastic
mulch are both effective in improving soil moisture and providing essential nutrients for the growth
of shallots, although plastic mulch tends to be more durable because it is not easily degraded.
