Abstract

The aims of this assessment were to evaluate the adaptation and the development of sound wave technology and sea weed nutrition application on hot pepper. The assessment for evaluating the adaptation of sound wave technology was conducted on hybrid variety (TM99) of hot pepper in Soropadan, Temanggung Regency. The hot pepper has been applied with sound wave length 3500 – 5000 Hertz and sea weed nutrition. The development of sound wave technology on hot pepper was conducted on farm level at 5 locations. Coverage area of the development was 10 hectares each. The sound wave technology development was held at Songgom Lor, Tengki, Banjaratma, Lemah Abang, and Kemurang Kulon Villages, Brebes Regency. Result of the assessment indicated that yield of the sound wave technology and sea weed nutrition application on hot pepper was 11.92 t/ha, otherwise on farmer management without sound wave technology and sea weed nutrition application was 8.36 t/ha. The sound wave technology and nutrition could increase yield of hot pepper by 42.6 %. The increasing yield of hot pepper on the development level was 26.96 %. The yield of hot pepper applied with and without sound wave technology and sea weed nutrition were 8.55 t/ha and 6.65 t/ha respectively. R/C ratio with and without sound wave and nutrition applications were 2.23 and 1.79, respectively.

Abstract

Land use changes from forest to agricultural farms have been incessantly occurring in Indonesia. This condition will have harmful effects on nature equilibrium if uncontrolled. Forest can effectively absorbed carbon, in contrast deforestation will result in the release of carbon dioxide (CO2) to the atmosphere. The research results indicated that significant carbon losses have taken place due to forest changes to agricultural farms.  Agro-forestry system can lessen these losses from vegetation, litter, soil and due to soil erosion. Agricultural farm with maize and peanut produced lower carbon than forest and vanilla agro-forestry.

Abstract

The preliminary research had been conducted to gather information on nutritive values of various plants such as kayu jawa (Lannea coramandelica), mengkudu (Morinda citrifolia), and kelor (Moringa oleifera) to be used as alternative feeds for ruminant. It was expected that the research could generate recommendation for the suitability of those plants as the sources of ruminant ration, new research plan on the comprehensive nutritive values of the plants, and agronomic tests and their procedure in dry land farming systems.  Three replicates of leave samples of 3 development phases (old leaves, well developed leaves, and young leaves along with branches) were taken from the three plant species. Therefore, the number of samples was 27. An Atomic Absorption Spectrophotometer was employed to analyze proxymat and mineral (Ca and P) content of the leaves. The research result showed that : (a) there was no interaction effect between the plant species and the leave development, (b) the content of all leave nutrients were affected by the plant species except that of fat, whereas the leave development significantly affected only the Calcium content, (c) based on the leave nutrient composition contained, M. oleifera and M. citrifolia could be used as alternative feed particularly for calcium and phosphorous supplies for ruminant in the Palu Valley to replace L. coramandelica which have been more popular, (d) As M. citrifolia and M. oleifera contained sufficiently high BETN level, these plants can be used as an alternative feed that can be mixed with other types of feeds containing non protein nitrogen (NPN), thus enhancing the overall feed nutrition. The research recommend that there is a need to proceed the research on L. coramandelica, M. citrifolia, dan M. oleifera as the source of feed for ruminant in the aspect of biological tests such as preferency and digestibitlity either in-sacco or in-vivo.  New experiments relating to growth measurements, productive and reproductive levels will comprehensively add the biological values of the three plants as the sources of ruminant feed.

Abstract

Credit aid programs can be used as a mean to improve the contribution of fishery sector. The impact of such credit on traditional fisheries was determined on the fishery productivity and their traditional fisherman income in Sulawesi Tengah Province. The research result showed that the credit was needed as an additional capital for the fishery sustainability. With such credit, the productivity of the fisheries increased as shown by sufficiently high incremental benefit which the fishermen achieved.  The  credit  also  affected  the  fisherman  household  in  making  decision  related  to  such  economic  behaviors  as productivity  activities,  working  time,  income  and  expenditure.  Thus  these  behaviors  were  analyzed  using  an  econometric approach with a simultaneous equation.

Abstract

Sheep is one of the preeminent commodities of Central Sulawesi in term of natural/pastural resources, climatic and cultural social condition. All varieties of local sheep in Central Sulawesi were generated from a cross-breeding between Fat-tail sheep (FTS) and Merbas sheep. The research was aimed at identifying the sheep phenotype characteristics as the criteria for sheep selection. The study was carried out in Palu city, and Biromaru sub district of Central Sulawesi from February to May and from November to December 2006. Data of sheep body sizes were collected from three different sites: Poboya (East Palu), Kawatuna (South Palu) and Loru (Biromaru). A total number of 412 sheep from the three sites were used and then randomly selected to obtain 102 (24%), 122 (10%), and 56 (28%) adult sheep from Poboya, Kawatuna and Loru, respectively. The research results showed that the local sheep population has been steadily decreased every year and currently there have been only 3270 sheep remained.  Among the three sites, the highest body weight of sheep was found with those from Biromaru. The average of birth weight,  weaning,  adult  males  and  females  body  were  3.25±0.53  kg,  11.25±3.33  kg,  42.00±6.245  kg,  and  30.14±6.28  kg, respectively. The body size of 18-24 month old sheep from Biromaru was also higher than those from the other sites.  Whereas for 36 month old sheep, those from  East Palu and Biromaru  were higher than those  from South Palu. The principal  Component Analysis (PCA) showed that the best criteria for sheep selection were breast diameter, body length, height of hip, and wide of tail.

Abstract

The objectives of the research were to increase the use of arenga starch and to achieve an optimal processing method of instant starch noodle made of arenga starch. In the research, the instant starch noodle was made using porridge methods. The methods of making instant starch noodle porridge including determination of starch/water ratio, duration of cooking, and optimal aging time. The starch/water ratio and duration of cooking was established based on inter-molecule binding freedom level (gelatinization and retro gradation) with a minimal score of 80% according to instant noodle requirement (SNI 01-3551-1994). While, the determination of aging time was based on physicochemical properties of instant starch noodle produced. The physicochemical properties included water content, inter-molecule binding freedom level, and cooking speed, cooking loss, tensile strength, elongation, texture and white level. The results of the research indicated that the best porridge method was done with starch/water ratio of 1:1.5 (v/v), cooking duration of 12 minute, and aging of 60 minute. Physicochemical properties of instant starch noodle porridge using such method resulting in water content of 7.62%, inter molecule binding freedom level of 82.70%, cooking speed of 2.42 minute, cooking loss of 6.15%, tensile strength of 0.018 MPa, elongation of 7.44%, texture of 10.27 N and white level of 76.30%.
