Abstract

The research aimed to study effect the application of river sand (RS), coconut coir (CC), and banana coir (BC) on growth and yield of rice (Oryza sativa L.) in Ustic Endoaquert. The research was carried out in a green house using 3 × 3 × 3 factorial design. The RS factor consists of three treatment levels which were 0% RS, 25% RS, and 50% RS. Meanwhile, the CC and BC consist of three treatment levels, where each level were 0 Mg ha-1, 10 Mg ha-1 and 20 Mg ha-1. The results showed that RS, CC and BC applications did not have significant effect on plant height. On the other hand, all ameliorant applications had significantly increase leaf length and the highest percentage increasing was in BC (13.49%). The leaf numbers and tiller numbers had relatively similar pattern, except BC that had significantly increased leaf numbers by 77.69% and amount of tiller numbers by 49.45%. Furthermore, for yield components, RS, CC and BC applications had significant increased panicle numbers by 37.76%. It was only RS and BC that increased panicle lenght and the best increasing of 26.82% on RS. Meanwhile, the BC application only increased the rice grain numbers.

Abstract

This study aims to determine the soil mineralogy and soil chemical properties at two rainfed soil pedons in Sidomukti, Gorontalo. This study was conducted at 2 pedon of rainfed paddy soils from Sidomukti Village Mootilango District of Gorontalo Regency. Implementation of the field based on the location of the example profile (pedon). The soil profile is made and sampled in accordance with the principles of soil surveying. Result of this research showed that Pedon PNS1 had easily weathered minerals (albite, sanidin and green hornblende) more than pedon PNS2. While the clay mineral content of pedon PNS1 dominated by smectite and kaolinite. Both pedon generally pH slightly acid to slightly alkaline and negatively charged clean, C-organic content is very low, bases-dd predominantly calcium (Ca-dd) with the sequence: Ca> Mg> K> Na, cation exchange capacity and base saturation dominant high and very high. However, the pedon PNS1 was better than pedon PNS2 of soil fertility.

Keywords: Mineralogy, chemistry, properties, pedon, soil.

Abstract

The research was aimed to study effect application of sea sand (SS), coconut coir (CC) and banana coir (BC) on the growth and yield of rice (Oryza sativa L.) planted at Ustic Endoaquert soil. The pot experiment was carried out using a factorial design with 3 factors. The first factor was SS consisted of three levels i.e.: 0%, 25%, and 50%. The second and third factors were CC and BC, each consisted of three levels i.e.: 0, 10, and 20 Mg ha-1. Application of SS and BC significantly increased leaf length where the highest increasing  percentage  was  16.47%  which  was  achieved  at  25%  SS  application.  Their  effect  on  leaf numbers and tiller numbers were relatively not similar pattern where leaf number only increased about 65.52% by BC application, while tiller numbers only increased about 10.77% by SS application. Furthermore, the application of CC and BC significantly increased panicle numbers to 29.53% and 29.05%, respectively compared to control. All ameliorants significantly increased panicle numbers, but the best was CC with the increasing up to 46.49% at 20 Mg ha-1 CC compared to SS or BC application. However, only coconut coir significantly increased the rice grain numbers.

Abstract

National rice production needs to be improved and maintained to meet the demands of fast growing population. One of the ways to meet this demand is through cultivating the rain fed land in many areas which its physical characteristics are challenging factor. This research aims at finding out the feedback of the rice production on the calcium fertilizer following the administration of river sand, beach sand, coco peat, and banana peat in ustic endoaquert. This research is implemented in rain fed field composed of vertisol soil in Sidomukti village of Mootilango Gorontalo, Indonesia. The subjects are randomly chosen and the treatments are separately implemented in two sub-group of vertisol soil. There are five treatments that were repeated three times, thus, there are 15 pieces of trials in each sub-vertisol groups. This research reveals that the administration of K fertilizer following the administration of river sand, beach sands, coco peat, and banana trunks fiber has significant effect on the number of grain, the weight of 1000 grains and the total weight of the grains. Meanwhile, the administration of K fertilizer following the administration of beach sand, coco peat and banana peat has significantly influenced the number of stalk, the length of stalk, and the total weight of the grains.

Abstract

This paper aims to assess the risk and action of climate change adaptation of specific food security sectors in Boalemo Regency based on the Minister of Environment and Forestry Regulation of the Republic of Indonesia Number P.33/MENLHK/Setjen/Kum.1/3/2016 on Guidelines for Climate Change Adaptation Action Formulation. Climate change is a necessity and has happened this earth. The impact of climate change on national food security occurs coherently, ranging from negative effects on resources (land and water), agricultural infrastructure (irrigation), to production systems through decreasing productivity, planting area and harvest. On the other hand, farmers have limited resources and ability to adapt to climate change. This requires concrete action by all stakeholders collectively in addressing the issue of climate change impacts. It is proposed to the District Government of Boalemo to address local climate change events with prioritization of adaptation options based on consideration of resource availability and constraints on the implementation of each adaptation option, including: (1) building of embungs, reservoirs and bending, drip irrigation, mulch, (2) development of draenase, improvement of irrigation, (3) adaptive seed breeding, use of organic fertilizer, (4) utilization of biopesticides, (5) alternative animal feeding training, and (6) consultation with mantri, animal age recording and calculation feed requirement. These efforts will be more useful if the rate of climate change does not exceed the ability to adapt. Anticipation and adaptation efforts need to be balanced with mitigation, ie efforts to reduce the source and increase the sink (absorber) of greenhouse gases.

Keywords : Risk, adaptation, climate change, food security.
