N2  - Gel soil amendments such as BOCP can be used to improve the condition of
sandy soil. Providing this soil amendment can improve the physical properties of
the soil, especially its ability to hold water. The ability to hold water can change
the pore size of the soil so that it can increase the soil's capacity to store water,
change the capacity of the soil to hold and conduct water and improve the soil's
ability to hold water and nutrients so that they are not easily lost. This research
was conducted to determine the effectiveness of the application of BOCP soil
amendment on water holding capacity. This research was conducted at the Soil
Science Laboratory, Faculty of Agriculture, University of Lampung from
November 2022 to May 2023. This research was designed using a completely
randomized design (CRD) with 5 treatments and 5 replications. The first treatment
is P0: no soil amendment, second treatment (P1): 7.5 mg.L-I BOCP, third
treatment (P2): 15 mg.L-I BOCP, fourth treatment (P3): 22.5 mg. L-I BOCP, fifth
treatment (P4): 30 mg. L-I BOCP. Observation variables include water holding
capacity, macro pores, aggregate distribution, soil texture and aggregate stability.
Data were analyzed using quantitative analysis. The research results showed that
the application of BOCP soil amendment had no effect on water holding capacity
before and after treatment.

Key words: Water holding capacity, gel soil improver and sandy soil
Bahan pembenah Tanah Gel seperti BOCP dapat dijadikan bahan untuk
memperbaiki kondisi tanah berpasir. Pemberian bahan pembenah tanah ini dapat
memperbaiki sifat fisik tanah khususnya kemampuan menahan air. Kemampuan
menahan air dapat merubah ukuran pori tanah sehingga mampu meningkatkan
kapasitas tanah dalam menyimpan air, mengubah kapasitas tanah menahan dan
melalukan air serta memperbaiki kemampuan tanah dalam memegang air dan hara
agar tidak mudah hilang. Penelitian ini dilakukan untuk mengetahui efektivitas
pengaplikasian pembenah tanah BOCP terhadap water holding capacity.
Penelitian ini dilakukan di Laboratorium Ilmu Tanah, Fakultas Pertanian,
Universitas Lampung pada bulan Novembern 2022 sampai dengan Mei 2023.
Penelitian ini dirancang menggunakan rancangan acak lengkap (RAL) dengan 5
perlakuan dan 5 ulangan. Perlakuan pertama yaituP0 : tanpa pembenah tanah,
perlakuan kedua (P1): 7,5 mg. L

-I BOCP, perlakuan ketiga (P2): 15 mg.L-I BOCP,
perlakuan keempat (P3): 22,5 mg. L-I BOCP, perlakuan kelima (P4): 30 mg.L-I
BOCP. Variabel pengamatan meliputi kemampuan menahan air, pori makro,
sebaran agregat, tekstur tanah dan kemantapan agregat. Data dianalisis dengan
analisis kuantitaif. Hasil penelitian menunjukkan bahwa aplikasi pembenah tanah
BOCP belum memberikan pengaruh terhadap water holding capacity sebelum dan
sesudah perlakuan.
