“…The profit from V. cylindrica yield in steep slope was higher than A. hypogaea yield on agroforestry system of F. moluccana-A. hypogaea as reported by Karmini et al (2017). The total cost, total revenue and profit related to F. moluccana and A. hypogaea agroforestry system was Rp 10,985,000 ha -1 cs -1 , Rp 14,000,000 ha -1 cs -1 and Rp 3,015,000 ha -1 cs -1 .…”

“…hypogaea and A. cadamba-G. max are feasible and applicable to rehabilitate and conserve the critical lands. Although planting of G. max was not profitable in some critical lands, the agroforestry system of A.cadamba and G. max still had many benefits from the aspect of ecology and conservation for long terms (Karmini et al 2017).…”

“…However, growing V. cylindrica as intercrop in vegetative (F. moluccana-V.cylindrica) and terrace combination system in different slope lands is highly beneficial when compared to growing G. max in A. cadamba-G. max agroforestry system. Karmini et al (2017) reported that growing G. max in A. cadamba-G. max agroforestry system involved total cost of Rp 11,019,000.00 ha -1 cs -1 , total revenue was Rp 3,500,000 ha -1 cs -1 , and the profit was Rp (-)7,519,000.00 ha -1 cs -1 . The planting arbor trees and shrubs densely on the terrace riser slope could suppress gravity erosion, allow intensive cultivation, add economic benefits and extend development of the landscape efficiently (Cao et al 2007).…”

Abstract. Karyati, Sarminah S, Karmini, Rujehan, Lestari VFE, Panorama WS. 2019. Silvicultural, hydro-orological and economic aspects of a combination of vegetative (Falcataria moluccana-Vigna cylindrica) and terrace systems in soils of different slopes. Biodiversitas 20: xxxx. Soil and water conservation techniques involving a combination of vegetative and mechanical systems will increase the benefits from both conservation aspect as well as economic aspect. This study was aimed at analyzing the silvicultural, hydro-orological and economic aspects of a combination of vegetative (Falcataria moluccana-Vigna cylindrica) and terrace system in soils of different slopes (a steep and a very steep slope gradient). The silvicultural parameters examined in this study were the ground coverage of V. cylindrica growth and survival rate, stem diameter and height of F. moluccana trees. The hydro-orological parameters included erosion rate, erosion hazard index, erosion hazard class, and erosion hazard level. The economic parameters included total cost, total revenue, and profit. The result showed that the survival rate, diameter increment and height increment of F. moluccana, and ground coverage of V. cylindrica in the land with the steep slope (>25-45%) was 90%, 2.02 cm year-1, 1.54 m year-1, and 80-90%, respectively. The erosion rate, erosion hazard index, erosion hazard class, and erosion hazard level in this steep slope was 0.38 ton ha year-1, 0.03 (low), I (very low), and very low, respectively. In the steeper ground (>45%), the survival rate of F. moluccana reached 90%, the V. cylindrica coverage was 70-79% and the diameter and height increment of F. moluccana was 1.63 cm year-1 and 1.19 m year-1, respectively. The erosion rate was 1.81 ton ha-1 year-1, erosion hazard index of 0.13 (low), erosion hazard class was I (very low), and erosion hazard level was low in the very steep slope land. The profit from V. cylindrica was Rp 3,865,000.00 ha-1 cropping season-1 and Rp 665,000.00 ha-1 cropping season-1 in steep slope and very steep slope, respectively. The application of the proposed combination of vegetative and terrace system could reduce surface runoff and erosion rate in the long term, in addition to providing short term economic benefits.

“…The combination must not only satisfy the biogeophysical condition of the land but also be compatible with the social, economic, and cultural aspect of the local community. Karmini et al (2017) reported that sengonpeanut-based agroforestry system in East Kalimantan made a profit of Rp 3,015,000.00/ha/season (226.96 USD/ha/season).…”

Sarminah S, Karyati, Karmini, Simbolon J, Tambunan E. 2018. Rehabilitation and soil conservation of degraded land using sengon (Falcataria moluccana) and peanut (Arachis hypogaea) agroforestry system. Biodiversitas 19: 222-228. Rehabilitation and soil conservation effort on degraded lands is not always a success. Multiple factors, such as the fieldâ€™ biogeophysical conditions and the choice of suitable plant species determine the effectivity of the rehabilitation program. Our research aimed to implement agroforestry system of sengon (Falcataria moluccana) and peanut (Arachis hypogaea) on degraded land at different soil slopes (a steep and a slightly steep slope gradient) and to analyze the effect of the system on silvicultural and hydro-orological aspects of the degraded land. The silvicultural parameters examined in this study were the ground coverage of peanut growth and the stem diameter and height of sengon trees. Meanwhile, the hydro-orological parameters included potential erosion rate, erosion hazard index, and erosion hazard level. Our study revealed that on the land with the slightly steep slope (15-25%), the survival rate of sengon reached 90%, the ground coverage of the peanuts was 70-80%, the diameter and height increment of sengon trees reached 2.47 cm/year and 17.58 cm/year, respectively. Meanwhile, the potential erosion rate was 20.05 ton/ha/year, with an erosion hazard index of 0.80 (low) and a low hazard level. In the steeper ground (25-40%), the survival rate of sengon reached 90%, the peanut coverage was 50-60% and the diameter and height increment of the sengon were 2.37 cm/year and 16.41 cm/year, respectively. In the steep ground, potential erosion rate was 45.50 ton/ha/year, with an erosion hazard index of 3.25 (moderate) and a low hazard level. We concluded that the rehabilitation and soil conservation using sengon-peanut agroforestry system effectively suppressed erosion rate to a low erosion hazard.

Karmini, Karyati. 2018. The various sources of household income of paddy farmers in East Kalimantan, Indonesia. Biodiversitas 19: 357-363. Some reports showed that agricultural and non-agricultural activities contribute to farmer household income. The objectives of this study were to identify the various sources of household income of paddy farmers, the average amount of every source of income, and the contribution of paddy farm income and non-paddy farm income to household income. This study was conducted in East Kalimantan Province, Indonesia. The two-stage cluster sampling was applied to select the study areas. The number of respondents was 380 paddy households. Descriptive statistics were used to explore, summarize, and describe the data. The sources of household income of paddy farmers in the study areas are from paddy farm income and non-paddy farm income. Paddy farm income is income from paddy farming. Non-paddy income is income from non-paddy farming jobs such as annual crops farmer, perennial crop farmer, employee, seller, fisherman, breeder of livestock, carpenter, and laborer. The average paddy farm income, non-paddy farm income, and total household income of paddy farmers in East Kalimantan in 2013 was Rp. 13,487,069.21 year-1, Rp. 20,920,464.31 year-1, and Rp. 27,360,640.28 year-1, respectively. The contribution of paddy farm income and non-paddy farm income to household income of paddy farmers was 49.29% and 50.71%, respectively.
