Abstract

Lembah Palu shallot variety is a high priority commodity in Palu Valley. However, developing this commodity has faced constraints in its management. Therefore, it is important to conduct study on land suitability evaluation for Lembah Palu shallot variety cultivation based on characteristics which are environmentally specific for growing the Lembah Palu shallot variety. The aim of the research was to evaluate quantitatively and qualitatively the land suitability of Bulubaseh watershed for developing Lembah Palu shallot variety cultivation in Donggala district. Soil survey conducted in the watershed was using stratified random method approach. The stratification was determined based on the research land units obtained by overlaying different types of maps including land use, topography and soil type maps resulting in nine land units. Soil samples from each land unit were randomly taken. The quantitative land suitability evaluation was done through analysis of farming financial suitability, while the qualitative land suitability was approached parametrically. The research results showed that generally the climate of the watershed was moderately suitable (S2) and about 884.86 ha or 57.3% of the total land area of Bulubaseh watershed was classified as marginally suitable (S3) with climate, land slope, solum depth and base saturation were the main constraints. The result of the quantitative land suitability indicated that financially Lembah Palu shallot variety is suitable to be developed as a farming system for the farmers in Bulubaseh watershed, Donggala district.

Abstract

Jatropha curcas Linn., is one of the oil plant producers, which can be processed to be the substitute fuel for diesel. The purpose of this research is to gain information of accession crosses compatibility level from different selected Jatropha. The study was conducted using seven accessions of Indonesia Jatropha planting material, which has a high productivity expectations, the HS-49, SP-16, SP-38, SP-8, SM-33, SP-34, and SM-35. The seven accessions were selected mass. Jatropha accessions used as an elder in the course of this research came from Gardens Jatropha Plant Germplasm Collection located in Asembagus–Situbondo. The crossings between seven accessions are not entirely successfully producing fruit and seeds. The crossing between SP-38 X HS-49 produced the highest number of fruits and seeds and followed by the crossing between SM-35 X HS-49. Of all the 42 crossing combinations, there are 14 crossing combinations that do not produce fruit and seeds at all.

Abstract

Indonesia is widely recognised as the centre of freshwater eel diversity. The recruitment of tropical glass eels generally occurs in multi-species schools. Identification of species present and recruitment patterns at regional and watershed scales are necessary to conserve eel biodiversity and manage eel populations sustainably. Data on eel taxonomy, phylogeography and biogeography are still limited in many areas. Research over the period 2009–2012 aimed to: 1) determine the species composition of glass eels recruiting to Palu River, flowing into Palu Bay on the Central Sulawesi Makassar Straits coastline; and 2) to develop a suitable method for live glass eel identification. Sampling was carried out over 29 months: January–April 2009, May–November 2010, April–December 2011 and March–November 2012. Two species were positively identified using the ano-dorsal vertebrae count (ADV) method, Anguilla marmorata and A.bicolor pacifica. The presence of other species (possibly one to three species) is important from conservation and biodiversity aspects. Temporal variations in species composition, with no apparent consistent seasonal or annual pattern raise questions requiring a multi-disciplinary approach.

Abstract

Local communities in many places have experienced in land use decisions, especially on Agroforestry systems. We examine the communities near Lore Lindu National Park (LLNP), who practicing the Agroforestry systems. This paper presents the typology of Agroforestry of the community near LLNP in Central Sulawesi. This research used qualitative-descriptive analysis by employing Geographic Information System (GIS), and The New Environmental Paradigm (NEP) analysis. The result shows that are two dominant agroforestry typologies in the research area: home garden and mixed garden. It is found that the mixed garden is dominant (combining many trees with cocoa, coffee, fruits, ect. According to the NEP analysis, it is also found that individual attitudes in Salua villagers are more dominant than in Simoro counterparts. The orientation in Salua is dominated by economic value. In contrast, Simoro has an altruistic value, that is, the land use system is not only for the economic orientation, but also for the socio-cultural value.

Abstract

Forest degradation in Indonesia is nearly 21,9 million ha. Effort to rehabilitate those forests is always constrained by funding availability, social problems and land fertility. The aim of this research was to compare the agroforestry (mixture of Paraserianthes falcataria and paddy), intensive monoculture and conventional monocultural systems. This research consisted of three treatments each treatment consisted of 10 plots. Data were analysed using homogeneity test, ANOVA, and LSD test using SPSS 19.0. Research was conducted in forest region in Lamida Village, Balangan District, South Kalimantan Province for the period of 2 years. Research result showed that at the first years, mean annual increment (MAI) of Paraserianthes falcataria in agroforestry system was 3.45cm in diameter and 3.66 min height as good as with intensive monocultural system of 3.21cm in diameter and 3.25 min height, whereas conventional monocultural system was 1.99cm in diameter and 1.75 min height only, which was significantly differentat 0.05 level from the first and second treatment. Agroforestry system also produced mount-paddy of 3.01 ton ha-1 in the first year and 2.98 ton ha-1 in the second year. Agroforestry system is the best system because beside it produces better growth for Paraserianthes falcataria, as good as, intensive monocultural system, this plantation system also creates vocation and improves social welfare.

Abstract

The objective of this study was to find out the optimum production of vanilla and the maximum increment of agar wood cultivated in an agroforestry system and to perform financial analysis to the system. This research conducted in Bukit Raya Village, Kutai Kartanegara Regency, East Kalimantan Province. Method of this research conducted by using theory of production, scientific principles to calculate the production of vanilla and the increment of agar wood by measuring the diameter and the highest of agar wood. To find out the financial worthiness by using Pay Back Period (PP), Net Present Value (NPV), Net benefit cost ratio (Net B/C) and Internal Rate of return (IRR). Results showed that the maximum production of vanilla at the age of 9 years old with a total production was 378 kg/ha, it can be harvested at the age 3 to 11 years while the increment of agar wood can be inoculated at the age 4-5 years with the age of inoculation during 2 years and gubal Agar wood can be harvested at the age 6 years to 25 years. The optimum increment of agar wood was reached at the age 15 years old with a total maximum was 14.5 m3/ha and the cultivation maintained up to 25 years because of financial reasons. The financial cultivation analysis of vanilla which combined with agar wood by using NPV, Net B/C and IRR theory at an interest rate of 15% was 54,592,000 rupiah, 1.95 and 21.5%, respectively. Equivalent annual annuity was 8,445,350 rupiah with a scale effort of 6 ha. It proved that the cultivation of vanilla and agar wood is feasible to cultivate by using Net present value, net B/C and IRR more than MAR.

Abstract

Central Sulawesi is the first rank of cocoa beans supplier in Indonesia. Almost 99% of cocoa plantations in this province are smallholder. Unfortunately, farmers have been converted their cocoa plantation to others plantation such as oil palm and coffee plantations. It was caused by continuous decreasing of productivity of the plantation since attack of pest and disease. Thus, productivity of cocoa plantation needs important intention. However, productivity is constrained by the environment capacities. The aim of this study is to analyze response of productivity for smallholders cocoa plantation based on the agro-ecosystem criteria, particularly productivity. Analyses method is descriptive and econometric model. Data were time series data from 2000 to 2011. The secondary data included production of cocoa beans, size area of cocoa plantation, price of cocoa and coffee beans, averages of fertilizers price, averages of pesticides price, and wages for agricultural labor in rural area. The study shows all of independent variables, except pesticide price significantly influence the dependent variable. Thus, all production factors prices, except pesticide price significantly influence the productivity. It means that the productivity of smallholder cocoa plantation is possibly to be elevated. The study recommends (i) tightening in controlling for policy of ceiling price of production factors; (ii) developing program of extensification for cocoa plantation; (iii) continuation of study in estimating for efficiency of production factors from an organic and organic; and (iv) analyzing for the other criteria of agro-ecosystem in performing of cocoa plantation.
