Development of sorghum processing industries is essential in expanding sorghum market as wells as it’s an economic value. Fertilizer is needed in planting. Nitrogen, phosphorus, and potassium availabilities are the most limiting factors for maximum growth and yield. Sorghum (Numbu Variety) was planted to evaluate the maximum and optimum rates of N, P, and K fertilizers. The research was conducted in Cikarawang field, Darmaga, Bogor from MarchJuly 2015 with multi-nutrient response method. Each experiment evaluated different rates of N, P, and K fertilizer with randomized complete block design and three replications. The fertilizer rates were 0, 50, 100, 150, and 200% of recommendation rate (100% N = 120 kg N ha-1, 100% P = 36 kg P2O5 ha-1, and 100% K = 90 kg K2O ha-1). The result showed relative yields of sorghum increased quadratically based on y = -0,0015x2 + 0,4011x + 67,571 for N, y = -0,0012x2 + 0,2917x + 78,457 for P2O5, and y = -0,001x2 + 0,2777x + 74,457 for K2O. The maximum rate for each nutrient was 160,4-43,7-124,9 kg N-P2O5-K2O ha-1. Fertilizer recommendation based on P threshold (no P) was 36,7-0,0-13,7 kg N-P2O5-K2O ha-1, K threshold (no K) was 22,0-0,0-0,0 kg N-P2O5-K2O ha-1, and no fertilizer needed on N threshold. The optimum rate fertilizer based on the yield vs. cost rule, therefore, the most economical recommendation would be 160,4-43,7-124,9 kg N-P2O5-K2O ha-1.

Benthos macroinvertebrates have been used as bioindicators to assess the waters quality of the stream, but still are very rarely to applied in West Papua streams. Benthos macroinvertebrates can describe the stream water quality so that very well be used as bioindicators, due to each species has a different tolerance to interference organic pollutants in waters. This study aimed to assess the water quality of Nimbai stream using benthos macroinvertebrates tolerance level and several water quality parameters. Data retrieval was conducted in JuneJuly and SeptemberOctober 2012 in seven stations (L1L7) from Nimbai upstream to downstream that connected to Prafi river. The water macroinvertebrates were taken using surber with mesh size 200 μm and then was identified at the family level. At L5 station near the oil palm waste disposal installations was contains oil and fat (<1-3 mg/l), which resulted in dissolved oxygen (DO) and pH is lower than the other stations. Similarly the value of H' is low (0.83), however, the value of C (0.79) was high that dominated by Oligochaeta. Famili biotic index (FBI) value obtained showed that water quality in the L1L4 stations was in good to excellent condition, but the quality at L5 station is classified as very poor. As the distance far away from the sources of pollution in the L5 station, water quality tends to improve as shown in the L6 and L7 stations. The result of this study shows the important benefits of benthos macroinvertebrates as bioindicators for assessing the quality of stream waters, and can be described aquatic environments disturbance to the benthos macroinvertebrates habitats in Nimbai stream.

Mutation is one of the ways to improve genetic variation in plant breeding so the target traits were more easily obtained. Grains of three varieties of maize (Bisma, Madura local, and Gumarang) were treated with gamma 60cobalt irradiation doses (0, 100, 200, and 300 Gy) before sowing then planted in a split plot randomized block design with three replication, to be evaluated for their morphology and agronomic traits. The Main plot was cultivars and sub plot was gamma radiation rates. There was no interaction between gamma rates and cultivars of maize, but increasing of gamma rates caused decreasing of some traits. Some traits such as plant height and leaves number were decreased significantly when gamma rate increased 100 to 300 Gy as well yield components such as grain weight and grain number per ear. Gamma 200 caused produce more ears than other rates. Bisma exhibited greater performance than Madura and Gumarang both of morphology and agronomic traits.

Low prices of rubber have been a serious problem to rubber farmers. The rubber based intercropping system offers a practical solution to this issue and increasing overall productivity. This experiment was aimed to determine the suitable spatial arrangements in rubber planting to facilitate long-term rubber-based intercropping systems. A ﬁeld experiment was established in a smallholder rubber plantation in the Tanah Laut District, South Kalimantan Province with an area of 700 ha and Musirawas District, South Sumatra Province with an area of 400 ha. The experiment using two planting patterns of rubber clone PB260: (1) single row planting pattern (SR) by 6 x 3 m, and (2) double row planting pattern (DR) by (18 + 2 m) x 2.5 m. The experiment showed that the girth of rubber trees in the SR system at the first tapping year was slightly bigger than that in the DR system, however, it was not statistically significant. The latex yield per tree of SR system was the same as the DR system, however latex yield per hectare of SR system has higher than the DR system, because the SR system have more population than the DR system. The DR system was proved to be a suitable planting system for long-term rubber based intercropping systems.

Madura cattle was selected into three groups by Madura people, there are karapan, sonok, and beef cattle. This selection based on morphological characters and pedigree. The differences of morphological characters in Sonok and beef cattle have not been reported. This research aimed to analyze morphological characters of both types, such as the differences in behaviors. This research was conducted from January-April 2016 at Sumenep and Pamekasan region, Madura Island. Preliminary was conducted with interviews, observation, and literature studies to obtain some characters which will be observed. Eighteen characters were observed in forty-two sonok cattle and fifty beef cattle. Qualitative data was analyzed by frequency analysis and use as input for principal component analysis (PCA) in Minitab 16 Statistical Software. The result shows that all of the observed cattle are divided into two groups. It indicates that sonok and beef cattle have different color around the eye area, the existence of back line, horn direction, and the existence of hump. However, further, observation is needed to find a robust character which can distinguish sonok and beef cattle for sonok selection.
