“…Sehingga untuk mendapatkan tinggi tanaman yang tertinggi maka sebaiknya menggunakan konsentrasi H1 (7,5 ml). Gambar 4.7 dan Gambar 4.8 menunjukan hasil rata-rata tertinggi pada perlakuan H1 (7,5 ml) hal ini sejalan dengan pendapat Santi (2016) bawa pemberian asam humat 7,5 ml dapat meningkatan mikroorganime dalam tanah sehingga pertumbuhan tanaman menjadi lebih optimal. Peran humat adalah meningkatkan nutrisi tanah, meningkatkan kesuburan, menstimulasi mikroorganisme dalam tanah sehingga lebih efisien dalam merombak bahan organik serta meningkatkan kelembaban pada tanah KESIMPULAN 1.…”

Penelitian ini bertujuan untuk mengetahui pengaruh metode aplikasi konsentrasi auksin IBA dan dosis asam humat terhadap pertumbuhan bibit stek kopi robusta. Metode yang digunakan yaitu menggunakan pola dasar Rancangan Acak Lengkap (RAL) faktorial yang terdiri dari 2 faktor dan 3 ulangan. Faktor 1 yaitu konsentrasi IBA yang terdiri dari 4 taraf. Faktor 2 yaitu dosis asam humat yang terdiri dari 4 taraf. Data yang diperoleh akan dianalisis menggunakan analisis ragam, jika terdapat perbedaan yang nyata maka akan dilakukan uji jarak berganda duncan pada taraf kepercayaan 95 %. Hasil penelitian menunjukan (1) terdapat interaksi antara aplikasi konsentrasi hormon auksin IBA dan dosis asam humat terhadap pertumbuhan bibit stek kopi robusta berpengaruh sangat nyata terhadap variabel pengamatan volume akar dan berpengaruh nyata pada variabel pengamatan panjang akar. (2) Pemberian hormon auksin IBA pada pertumbuhan bibit stek kopi robusta berpengaruh sangat nyata terhadap variabel pengamatan diameter batang dan berpengaruh nyata terhadap variabel pengamatan tinggi tanaman (3) Pemberian asam humat pada pertumbuhan bibit stek kopi robusta berpengaruh sangat nyata terhadap variabel pengamatan volume akar dan panjang akar namun berpengaruh nyata terhadap variabel pengamatan tinggi tanaman dan jumlah daun

Ebony is one of slow-growing spe- cies), that of suspected to be the triggering factors to prone to extinction. In addition, the nature of ebony seeds is recalcitrant, so they cannot be stored for a long time. Other factors affecting seed germination are the degree of maturity, size, and weight of the seeds. Seeds harvested before the physiological maturity level would not have high viability and even could not germinate well due to the in-sufficient of food reserves, and un-perfect embryo formatio. Bio-fertilizer is used to help accelerate the growth of ebony. This study aims to analyze the combination of bio fertilizers which would be giving a better effect on the physiological activity and growth of ebony seedlings. Morphological and physiological variables measurement were used in this study. The research design used a Completely Randomized Design at a real level of 5%. If the fingerprint results obtained have a real effect, then a further test of the Duncan Multiple Range Test is carried out. Re- search results showed that seed coating treatment of 45% Penicillium microbial solution + seed coating) gave the best results in each variable of both growth and physiology of ebony seedlings, while in the treatment without seed coating, Sargassum microbial solution 30% indicates good results in each variable of growth and physiology of ebony seedlings. Treatment with the immersion of seeds in microbes can produce a high percentage in each variable.

Dinoyo sub-watershed is one of the watersheds that drain water from Argopuro Mountain through the Panti and Rambipuji Districts. Land-use changes in the upstream area have reduced the function of water absorption and increased soil erosion. It causes drought during the dry season and flooding during the rainy season which is a characteristic of critical land. This study aims to map the level of criticality of the Dinoyo sub-watershed area and its relationship to nutrient availability. This study used the scoring and weighting method of four main factors that affect the critical value of land (land cover, slope, management, and erosion level). The layers then executed using the Gis program. The result of this analysis produces a land criticality map. Based on the analysis, the up-stream section has high nutrient availability compared to the middle and downstream regions. There are two classes of land criticality, which are rather critical and substantial criticism. The area included in the rather critical was 1,723.34 ha dominated by forest land use. A coffee plantation dominates a sizeable critical area of 2,333.88 ha. From regression analysis showed that organic matter had the most influence on the criticality of land.
