Abstract

Puddle is one of the damaging effects that can reduce the quality of pavement. The quality of road construction with asphalt pavement is determined by its stability, flexibility, and durability which are the determinants of the quality of pavement. In this research, Buton Rock Asphalt (BRA) was used as an alternative to improve the performance of asphalt mixture that can be impacted by the mentioned determinants. BRA is Asphalt Buton type 5/20 grain Asbuton type which has penetration value 5 mm and bitumen content of 20%. The aim of this research was to measure the best percentage of BRA level from percentage of BRA substitution (25%, 50%, 75%, 100%) as filler and Marshall mix parameter value of Pen 60/70 asphalt with the best BRA Substitution on immersion water with variation of immersion time 30 minutes, 24 hours. Based on Marshall test result with BRA substitution, percentage variation obtained the best stability at 50%, BRA percentage was 1450,78 kg, density 2,45 gr / cm3, VIM equal to 4,17%, VMA equal to 21,76%, VFA equal to 80, 86% and 2.5 mm of flow, and Marshall Quentient of 583.40 kg / mm. This suggested that the use of BRA as a filler substitute material at 50% percentage was the best percentage of BRA substitution with the highest stability value and it met the requirements of other Marshall parameters. The best stability value without substitution with a muddy water bath was 1098.95 kg, with the best BRA substitution of 1476.34 kg. This indicated that the use of BRA as a filler substitute material had an effect on increasing the stability value of AC-WC asphalt mixture to muddy water immersion.

Abstract

The availability of power thresher for custom hiring services has accelerated the mechanical power use in small-scale rice threshing operation in Kampar Regency. This research attempts to determine the need, used capacity, and seasonal work of power thresher and to analyze the cost, profit, and break-even of power thresher hire services managed by farmer groups.  Data were collected from 15 power threshers from 10 custom-hiring services group selected using purposive sampling technique in seven districts of Kampar Regency. The interviews with group managers, custom operators, and mechanics were conducted during the main growing season in 2012.  The results showed that the number of power threshers on farmer groups was limited and most of them, however, still worked under capacity. The power thresher was employed only for group members with custom work about 64.9 t/season.  The seasonal work was more than break-even point of about 7.7 t/season, so the custom-hiring services of power thresher are profitable.   Therefore, the method can become an alternative source of income and also extend the power thresher adoption amongst rice farmers in the region.

Abstract

Palm oil commodity is plantation sub-sector commodity which can increase the income of farmers and communities, providers of raw material processing industries that create added value. Cultivated by smallholders self consists of land area, peatlands tidal, coastal peatlands and coastal lands. Differences typology of this land will contribute to the different productions. Generally, this study aimed to analyze the factors of production and farming oil palm, according to the typology of land Specifically aimed to analyze the production and cultivation of oil palm as well as the dominant factor affecting the production Kalapa smallholders' according to the typology of the land and to formulate policy implications of oil palm development patterns of the people in Indragiri Hilir in Riau province. To answer this research analyzed with descriptive statistics and build a multiple regression model with dummy variables Ordinary Least Square method (OLS). Memperlihatan research results that palm oil production and farming on land typology highest compared with tidal peat, peat coast, and coastal lands. Oil palm farming income on a non-pattern land typology best compared with other lands (peat tides, coastal peatlands, and coastal land). The dominant factor affecting the production of palm oil in Indragiri Hilir is the amount of fertilizer, labor, plant age, herbicides, and soil typology dummy land. Policy Implications development of oil palm plantation in Indragiri Hilir in order to increase production, productivity and farm income oil palm can be through the construction of roads production, provision of means of production and palm oil processing industry to shorten the distance and shorten the time of transport that TBS of oil palm plantations to the factory. Furthermore, the use of fertilizers, labor and land typology is very responsive to TBS production. Therefore, in the farming of oil palm cultivation should follow the recommended technical.

Abstract

Heriyanto et al, 2018. Analysis of the Production Factors of the People's Palm Oil According to the Land Typology in Indragiri Hilir Regency, Riau Province. JLSO 7(1):14-25. Palm oil commodities are one of the plantation sub-sector commodities that increase the income of farmers and the community, provide processing industry raw materials that create added value. The land cultivated by independent oil palm farmers consists of land land, tidal peatlands, coastal peatlands and coastal land. The difference in typology of this land will contribute to different production. The research aimed to analyze the oil palm production and the dominant factor affecting oil palm production according to the typology of land in Indragiri Hilir Riau Province. The data were analyzed using descriptive statistics and built multiple regression models with the dummy variable method of Ordinary Least Square (OLS). The results of the study showed that the production of oil palm cultivation on land is the highest compared to the typology of tidal peatland, coastal peat and coastal land. The dominant factors affecting palm oil production in Indragiri Hilir Regency were the amount of fertilizer use, labor, age of plants, herbicides and dummy typology of land. In order to obtain optimal production, this study recommended doing oil palm farming in accordance with the correct cultivation techniques in accordance with the characteristics of land typology. Besides that the use of balanced fertilizer (elements of N, P, and K) in accordance with the recommended needed to be applied.
