Abstract

Perubahan iklim telah terjadi di wilayah Indonesia. Perubahan iklim memengaruhi pertanian melalui dampaknya terhadap pertumbuhan, perkembangan, dan hasil tanaman. Penelitian indikasi perubahan iklim dan dampaknya terhadap produksi tanaman padi di Indonesia (Sumatera Selatan dan Malang Raya) pada tahun 2011-2013 telah dilakukan.  Penelitian ini bertujuan untuk mengkaji adanya perubahan iklim dan bagaimana dampaknya terhadap produksi padi di Indonesia. Kajian ini menggunakan data dari temperatur, curah hujan, agroklimat, dan produksi tanaman padi serta data sosial ekonomi. Metodologi penelitian ini adalah deskriptif eksplanatori menggunakan konsep asesmen risiko dimana risiko (risk) merupakan fungsi dari bahaya (hazard) dan kerentanan (vulnerability). Hasil kajian menunjukkan bahwa di Indonesia telah terjadi perubahan iklim dengan indikasi peningkatan suhu, perubahan pola curah hujan, perubahan hitergraf, dan perubahan klasifikasi Oldeman.  Hasil penelitian juga menunjukkan bahwa pertanian sangat rentan terhadap dampak perubahan iklim dengan indikasi level bahaya yang tinggi pada penurunan produksi padi sebagai akibat peningkatan suhu dan perubahan pola curah hujan.  Beberapa daerah di Sumatera Selatan maupun Malang Raya mempunyai risiko tinggi pada penurunan produksi tanaman padi.  Umumnya Indonesia mempunyai tingkat risiko tinggi pada penurunan produksi padi dengan rerata 1,37 % per tahun dan berpotensi menyebabkan penurunan produksi pangan nasional. Climate change has been occurred in Indonesia. Climate change affects agriculture through its impact on growth, development, and crop yield. Research on climate change indication and its impact on rice production in Indonesia (South Sumatra and Malang Raya) in 2011-2013 has been done. The study aimed to assess climate change and how it impacts rice production in Indonesia. This study used data of temperature, rainfall, agroclimate, and rice production and socioeconomic. The methodology of this research was descriptive explanatory using risk assessment concept where risk was a function of hazard and vulnerability. The results of the study indicated that in Indonesia has been ocurred climate change with indications of temperature increase, changes in rainfall patterns, changes in hitergraph, and changes in Oldeman classification. The results also show that agriculture is highly vulnerable to the impacts of climate change with an indication of high hazard levels in the decline of rice production due to rising temperatures and changes in rainfall patterns. Several areas in South Sumatra and Malang Raya have a high risk of decreasing the rice production. Generally Indonesia has a high risk level on the decrease of rice production with an average of 1.37% per year and potentially causes the decline of national food production.

Abstract

Efforts to intensify oil palm (Elaeis guineensis Jacq.) are needed to increase productivity close to the actual production potential of oil palm crops. The productivity and growth of oil palm is partly controlled by the relationship between the top of the plant (the leaf) and the bottom of the plant (root). This study aims to find out the effect of root pruning and the number of fronds on the growth, production and quality of oil palm products. The research was conducted for 12 months from February 2018 to January 2019 in gardens owned by the community of Petapahan Village, Tapung District of Kampar Regency, Riau. The research was conducted experimentally using split plot design which is grouped based on different plant age (5 years, 10 years and 15 years). The main plot is the pruning of oil palm, Normal, Light, and Heavy fronds. The plot is trimming the roots of oil palm 75%, 50% and 25%. The results showed that root pruning and the number of fronds did not affect the interaction of observational premeters. Pruning the roots independently gives a noticeable influence on the content of mesocarp oil. Self-trimming of the fronds has a real effect on the total increase in oil. Plant life has a noticeable effect on enhancement, total oil, mesocarp oil and free fatty acids.

Abstract

Hanjeli has a hard rind, so it takes a peeler and polisher to process it. One of the machines used is the Hanjeli Polishing Machine AGR-RM40 in the Faculty of Agriculture, Padjadjaran University. However, this machine has the disadvantage that most of the hanjeli seeds are crushed and are not polished. This is due to the polishing space which is quite narrow so that it puts great pressure on the hanjeli seeds during the polishing. Meanwhile, the existence of not polished hanjeli was caused by friction between the cylinders and hanjeli which is not maximum. Therefore, this machine needs to be modified to improve the results of a better polishing. The method used in this research was engineering with several stages, such as designing a polishing unit, analysis, and performance testing on hanjeli batu and hanjeli pulut. The modification of the Polishing Unit on Hanjeli Polishing Machine (MPBH-0219) has a cylinder length dimension of 167 mm and a diameter of 37.9 mm. Based on the performance test, this machine is good and worth using where actual capacity is obtained 35 kg / hour, 96 % engine efficiency, 58,46 % dumping yield, 0.50 performance, and 1.30 kW actual power requirements. Keywords: Hanjeli Polishing Machine, Modification, Performance Test.

Abstract

Climate change, especially air temperature and rainfall, impacts the agricultural sector, one of which is the reduction of maize production. As an anticipatory effort to reduce maize production due to climate change, a study is needed to identify the possible hazard, vulnerability, and risk of maize yield reduction at the sub-district level in the largest maize-producing center in West Java, Garut Regency. After identifying areas with high or very high levels of potential yield reduction risk, a strategic adaptation that can be applied to deal with climate change can be identified. The method used in this research is descriptive quantitative. The data used include temperature, rainfall, planting area, harvest area, production, productivity, and socio-economic data of farmers obtained from LAPAN, BPS, Garut Regency Agriculture Office, and other related sources. The results of the study stated that the areas with a potential risk of production decrease at a very high level (IR ˃0.81) are in Wanaraja and Malangbong sub-districts; high level (IR: 0.61-0.80) are in Cisewu, Pakenjeng, Banyuresmi, and Limbangan. Meanwhile, the potential risk level of maize productivity decrease is very high (IR ˃0.81) in Cisewu, Pamulihan, Banyuresmi, Malangbong, and Limbangan; high (0.61-0.80) in Bungbulang, Singajaya, Cilawu, Bayongbong, Leles, Leuwigoong, Cibiuk, Cibatu, and Selaawi. Adaptation strategy to minimize the potential risk of reduced maize yields can be done by using superior hybrid varieties, managing planting time, water management, minimum tillage, and mixed cropping.

Abstract

The phenomenon of extreme weather events as a result of the impact of climate change can cause threats to agricultural systems, including soybean (Glycine max L.). Soybean is the main source of vegetable protein, which is sensitive and vulnerable to climate change. Therefore, research has been carried out through the identification analysis of changes in extreme weather events and analyzed for their correlation with soybean crops in Garut Regency to determine the effect of extreme weather elements on soybean production. The method used in this research is descriptive quantitative, using trend analysis on extreme weather with data on extreme weather elements such as maximum rainfall, maximum temperature, minimum temperature, wet spell, dry spell, the largest wind speed, and trend analysis on soybean production and productivity. Data for the research were obtained from BUTPAAG LAPAN Garut Regency, Garut Regency Agriculture Office, and other related sources. The correlation analysis used is the Pearson correlation with a significance level of 5%. The results showed that climate change impacts extreme weather changes in the Garut Regency area, with increasing extreme weather trends. However, extreme weather changes were not significantly correlated with soybean production. In this research, only the maximum rainfall and the largest wind speed were significantly correlated with soybean productivity.Keywords: correlation analysis, trend analysis, extreme weather, Garut regency, soybean production.

Abstract

Climate change, especially temperature and rainfall shifting can be a threat to the agricultural sector, i.e., the decrease in rice yields in Majalengka Regency as the West Java rice production center. As an anticipatory measure to deal with that problem, a study is needed regarding the level of hazard, vulnerability and risk of climate change impacts in Majalengka Regency. This research aims to identify climate change and examine the level of hazzard, vulnerability and risk of the impact of climate change on rice production in each sub-district in Majalengka Regency. The method used in this research is descriptive quantitative. The data used in the analysis of the level of hazard, vulnerability and risk of climate change include temperature, rainfall, production, productivity, planting area, harvested area and farmers' socio-economic data obtained from Statistics Indonesia; Meteorology, Climatology, and Geophysical Agency; Agriculture Office of Majalengka Regency and other relevant sources, while farmer interview data were used in analyzing strategic adaptation options. The results of the study stated that areas with a very high potential risk of decreasing rice production (Risk Index or RI > 0.80) were in Kertajati District; the risk level of rice production in the high category (RI 0.61-0.80) was in Bantarujeg and Ligung Districts. Meanwhile, areas with a very high level of risk of decreasing rice productivity (IR) > 0.80) are in Bantarujeg District; high-risk level (IR 0.61-0.80) was in the Districts of Lemahsugih, Malausma, Argapura, Kertajati, Jatipuh and Ligung. The adaptation efforts that can be made to reduce the risk of decreasing rice production are the use of superior seeds, crop rotation, intermittent irrigation systems, acceleration of land preparation by mechanization, application of the jajar legowo cropping system, and integrated pest management measures.
