Along with the increasing the of the land-use change of the fertile agricultural land in Java, the better awareness has been subjected to the importance of function peat land for agricultural development. Cassava (Manihot esculenta Crantz) is a tuber plant that potentially developed as important carbohydrate source. The objective of this research was to identify superior cassava variety candidate of selected cassava developed by of Research Centre Biotechnology, LIPI which has high adaptation capability and yield in Central Kalimantan peat land area. This research was conducted from July 2010 through May 2011 in Central Kalimantan Province (Kalampangan dan Pulang Pisau in total of area 1.5 and 2.25 ha respectively). There were three genotypes of cassava tested, i.e. Iding (high amylose), Gebang (low amylose), and Menti (high starch) compared to Adira 4 (35 ton/ha) and Darul Hidayah (102.1 ton/ha). The variables observed were plant height (cm) and tuber weight (grams). Observations were conducted at the age of 10 months. Data was analyzed using SPSS version 16.0. The results showed that the plant height and yield were higher in Pulang Pisau than Kalampangan even though the difference is not significant (P ≤ 0,05). Darul Hidayah has highest plant height and yield, 229.8 cm and 2271 g respectively among other genotypes/varieties grown at Pulang Pisau even though the value was not significant, whereas in Kalampangan, Darul Hidayah showed the lowest yield (670 g). Based on the data obtained, the Darul Hidayah variety can be cultivated by farmers in Pulang Pisau peat land to fulfill the availability of superior cassava seedlings for food, feed and industry.

Cassava (Manihot esculenta Crantz., Euphorbiaceae) is an important dietary carbohydrate source for approximately 800 million people in the tropics. It is a potential crop for food, feed, and industry. Cassava breeding through conventional approaches are hampered with some limitations which resulted in a low number of superior varieties. The objective of this research was to generate several mutant lines with higher yield and starch content. This research intended to identify the second generation (M1V2) Jame-jame and Adira-4 variant cassava mutants from gamma ray irradiation. Jame-jame is a local genotype from Halmahera (local high yielding genotype, sweet, and potential)  and Adira-4 is an Indonesia national variety of cassava. Mutant diversity appears on the plant height, plant branching, and plant tubers that harvested at 10 months after planting (MAP). Our results showed the positive correlation between plant height, first branching height, tuber weight, number of roots, and number of economic roots. Based on tuber weight and number of economic tuber there were 9 potential mutants (putative).  Based on the stability test, there were 6 potential stable mutants (putative) by first branching height, tuber weight, total number of tubers, and total number of economies tuber, namely: V5D1-(2), V5D1-2(2), V5D1-3(2), V5D1-4(3), V5D2-2(2), and V5D2-6(2). Keywords: local genotype, M1V2, storage root, characters,  stability.

Growing dogs were divided into three groups and were fed on a control (rice) diet, a diet in which cassava (Manihot esculenta Crantz; gari) was used as the carbohydrate source, and the rice diet to which cyanide (equivalent to that present in gari) was added. Each group consumed its diet for 14 weeks, during which plasma thiocyanate concentration and plasma lipase (EC 3.1.1.3) activity were monitored. Plasma free amino acids were determined from pooled samples taken at the end of the experimental period, and the insulin status of the dogs was evaluated using the gluconeogenic index. The dogs were killed and the pancreas examined for histopathology. Dogs fed on both gari diet and the rice+cyanide diet generated significant amounts of thiocyanate when compared with the controls, with the rice+cyanide group having higher plasma thiocyanate than the gari group (P < 0.01). Plasma lipase activity rose significantly at the end of the experimental period in the dogs fed on gari (P < 0.05). Gluconeogenesis from protein was greatest in the dogs fed on gari, five times greater than that in the control dogs, while gluconeogenesis from protein in the dogs fed on rice+cyanide was approximately twice as high as that of the control dogs. Histopathological examination of the pancreas showed haemorrhage, necrosis, fibrosis and atrophy of the acinar tissue and fibrosis of the islets of Langerhans in the dogs fed on gari. The pancreas of the dogs fed on rice+cyanide showed similar lesions but haemorrhage was not prominent and fibrosis was more marked. The present study indicated that a hypoinsulinaemia developed which was more severe in the animals fed on gari than in the dogs fed on the rice+cyanide diet and that the condition was not related to the level of plasma thiocyanate or the histopathology observed.

Spatial Concept

Land allocation for agricultural lands is required when the region have potency to be developed while the same time, conservation aspects are still considered. Central Kalimantan Province with total areas of 15, 451, 287 hectares has potential land available for agricultural development. At initial stage, with a landscape scale, land resource potential is needed to be assessed for planning purposes. The aimed of this study was to design the spatial concept of agricultural landscape planning on sustained basis. Methodology used in this include concept of land capability evalution (LCE) approach and geographic information system (GIS) application. The result of evaluation showed that Central Kalimantan was classified into 6 land capability classes i.e class II, III, IV, VI, VII, and VIII with several limiting factors such as peat depth, drainage, slope, and texture. Within GIS environment, the result of spatial analysis shown that total areas of agricultural land region was 9,571,231 hectares or 61.95% of total Central Kalimantan province. This indicates that the lands are still widely available for agricultural development.  These areas are located not only in wetlands typology but also found in dryland areas. Specific program that specific to location can then be formulated in order to develop the areas.

The former quartz sand excavation land is a potential land for agricultural land. This land generally contains sufficiently high sand and very low fertility. The use of new superior varieties adaptive and tolerant can increase production. This study was carried out in the experimental field owned by BPTP in Gantong Village, East Belitung Regency, Bangka Belitung Islands Province. The design used was a randomized block design using three types of superior varieties, namely Inpari 22, Inpara 3, and Inpara 5. Each replication was repeated 3 times. Planting uses the jajar legowo system 4:1 (25 x 15) x 40 cm with 2-3 seedlings/planting holes. The fertilizer used is NPK 15:15:15 300 kg/ha and Urea 100 kg/ha. Urea fertilizer is given 3 (three) times each when plants are 7 days after planting (HST) as much as 25%, 25 HST as much as 50%, and 45 HST as much as 25% dose. Lime and organic fertilizer with a dose of 1 ton/ha each. Parameters observed included plant height, number of tillers, and production. The results of the study indicate that the growth of Inpara 5 has better than other varieties. The highest plant height and number of tillers are owned by Inpara 5, but not significantly different than Inpara 3 and Inpari 22. From the aspect of production Inpara 5 (2.23 t/ha) is significantly different from the varieties Inpara 3 (1.51 t/ha) and not significantly different from Inpari 22 (2.21 t/ha).

The North Sumatera province has the fifth largest goat population in Indonesia after Central, East, Lampung and West Java. Meanwhile, solid and liquid goat manures have great potential as a source of organic fertilizer. Therefore, this study aims to examine the potential of goat manure as a source of organic fertilizer and its role in improving soil quality, growth and crop production. The data were collected from the Central Bureau of Statistics and the results of previous studies. Furthermore, the potential of goat manure was calculated by multiplying the total goat population in North Sumatra by the goat manure production /head/day and converted to one year. The parameter measured was the total goat population in North Sumatera, goat manure production/head/day, and the covered agricultural land area. The results showed that goat manure only fulfilled 3.69% of the agricultural land area in North Sumatera. In addition, the case study in Deli Serdang District showed that the application of goat manure compost with biourine and balanced inorganic fertilizers increased red chilies’ productivity by 46%. Therefore, it was concluded that the potential of goat manure as organic fertilizer is still very low.
