Abstract

Government of Indonesia has set the rice surplus target of 10 million tons in 2014. This program requires integrated and comprehensive efforts of all stakeholders in central and local levels. The policy was set forth in form of Permentan No. 45/2011 and then implemented by the Director General of Indonesian Agency for Agricultural Research and Development (IAARD) through a decree No. 178.1/Kpts/OT.160/I/7/2012 about For- mation of Integrated Cropping Calendar and Climate Change Task Force in each Assessment Institute for Agricultural Technology (AIAT) for whole Indonesia. Additionally, IAARD has developed an Integrated Cropping Calendar Information System as a reference for policy makers in planning food crop management. The information system contains the next planting season estimation at sub-district level, which includes the initial time of planting, disaster-prone areas (flood, drought, and pests/diseases), as well as technology recommendation (varieties, seed, and fertilizer). In order to make an operational standard for AIAT Task Force, the Technical Guideline of Integrated Cropping Calendar and Climate Change is imperative. This article contains the summary of the technical guideline for AIAT Task Force in support of Permentan No. 45/2011 and climate change adaptation for food security. An implication of implementation of the AIAT Task Force is an important part in improving the content of Integrated Cropping Calendar Information System that fits the needs of farmers and extension workers in the field in order to achieve the rice surplus target.

Abstract

Waktu awal tanam padi merupakan salah satu aspek pertanian yang menggambarkan waktu mulai menanam padi yang diduga bervariasi antar tempat. Penelitian bertujuan untuk mengkaji variasi waktu tanam tanaman pangan di wilayah timur Indonesia. Awal waktu tanam tanaman pangan yang dilakukan petani pada Musim Tanam I (MH) ditentukan apabila 8 persen dari luas baku kecamatan yang bersangkutan telah ditanami, awal tanam Musim Tanam II (MK I) ditentukan pada saat 6 persen dari luas baku sawah telah ditanami. Analisis dilakukan dengan menggunakan data luas baku dan luas tanam bulanan untuk tanaman padi sawah, padi ladang, dan jagung. Data yang dikumpulkan adalah data per kecamatan untuk periode tahun 2000 sampai dengan tahun 2009 yang diperoleh dari Badan Pusat Statistik (BPS). Penelitian menunjukkan awal waktu tanam yang hampir sama untuk semua komoditas yaitu pada pertengahan sampai dengan akhir Oktober (Okt ll/lll) untuk MH. Untuk MK I, petani melakukan penanaman padi ladang dan jagung terlebih dahulu mulai akhir Januari sampai dengan awal Februari (Jan lll/Feb I)dan juga pertengahan sampai akhir Februari (Feb ll/lll) untuk padi sawah. Realisasi waktu tanam petani ini sangat ditentukan oleh awal musim hujan yang terjadi di wilayah timur Indonesia, sehingga hanya beberapa tempat yang bisa melakukan penanaman padi pada MK I, dan umumnya diganti dengan tanaman palawija. Apabila informasi awal waktu tanam ini dipetakan secara nasional, maka usaha pemenuhan kebutuhan tanaman pangan dapat difokuskan dengan memperhatikan tempat dan waktu kegiatan budidaya tanaman pangan.Planting time of food crop by farmers is expected to be varied among regions. The study aimed to examine the planting time variation of food crops in eastern Indonesia. Commencing planting time of planting season I (MH) is determined when 8 percent of the total food crop area have been planted, while commencing planting of planting season II (MK I) determined when 6 percent of the area have been planted. Analyses were performed using the food croparea and monthly planted area forirrigation paddy, rainfed paddy and maize. The collected data are distributed in each sub-district between 2000 and 2009 and obtained from the Central Statistics Agency (BPS). Research result showed commencing planting time forrainy season (MH) is almost similar forall food crops in the midto late of October(Oct II / III). For dry season (MK I), farmers plants rainfed paddy and maize crops in advance from late January to early February (Jan HI / Feb I) as wellas midto late February (Feb II / III) forirrigated paddy. Actual planting time is largely influenced bymonsoon in eastern Indonesia, therefore only a fewplaces that cultivate rice inMKI, butgenerally they plant secondarycrops. When the commence of planting time information is mapped nationally, efforts to fulfill the food crops requirement could be planned appropriately considering the local time of food crops cultivation.

Abstract

Perubahan iklim global yang berimbas terhadap pola hujan menjadi kendala bagiProgram Peningkatan Produksi Beras Nasional (P2BN). Salah satu implikasi dariperubahan iklim adalah pergeseran awal dan akhir musim tanam yang berdampak negatif terhadap pola tanam dan produktifitas tanaman. Penelitian ini bertujuan untuk menyusun atlas kalender tanam Pulau Sumatera dengan skala 1:250.000, yang dapat dijadikan sebagai panduan untuk menentukan potensi pola tanam dan waktu tanam pada tanaman semusim (terutama padi) sampai tingkat kecamatan berdasarkan potensi dan dinamika sumber daya iklim dan air. Atlas kalender tanam ini disusun melalui beberapa tahapan yaitu (i) pengumpulan data dan wawancara dengan petani; (ii) analisis waktu tanam; (iii) verifikasi lapang; dan (iv) penyusunan atlas. Selain memetakan kebiasaan waktu tanam yang diterapkan petani saat ini, atlas kalender tanam ini juga dilengkapi dengan kalender tanam berdasarkan tiga kondisi iklim, yaitu pada saat curah hujan tinggi (tahun basah), pada saat curah hujan rendah (tahun kering), dan pada saat curah hujan normal (tahun normal). Atlas kalender tanam dapat menjadi panduan bagi penyuluh pertanian maupun petani dalam menjalankan usahataninya secara berkelanjutan. Beberapa manfaat atlas kalender tanam adalah untuk menentukan waktu tanam tingkat kecamatan, menentukan rotasi tanaman berdasarkan potensi sumberdaya iklim dan air, mendukung perencanaan tanam tanaman pangan semusim, dan mengurangi dampak buruk pergeseran musim tanam terhadap kerugian petani. Global climate change causes change in the rainfall pattern and becomes a constraint to the national program on rice. The change implies both the shifting of the cropping time and the change in cropping pattern of annual crops that eventually decrease crop productivity. The aim of this research is to provide the cropping calendar map of Sumatera island at 1:250.000 scale that can be applied as reference in determining time of planting and cropping pattern for each sub district that suit to the dynamic of climate and water resources. This cropping calendar is arranged through several steps: (i) climate data collection and farmer’s interview; (ii) analysis of planting time; (iii) field verification; and (iv) mapping process by delineating of cropping pattern. This map is prepared for the farmer’s condition in different climate anomaly scenarios such as La-Nina, El-Nino, or normal. This cropping calendar map can be used as a reference for farmers and extension workers in planning a sustainable farming.Cropping calendar map serves several function, i.e. providing spatial and tabular cropping pattern for crop land at the sub-district level, determining cropping rotation in each sub district based on the existing climate and water resources, supporting the planning of cropping season and pattern, especially for seasonal food crops, and reducing the negative impact of climate anomaly and risk of farmer’s losses.

Abstract

Dalam menetapkan waktu tanam tanaman padi petani kebanyakan mengandalkan kebiasaan turun temurun, padahal kondisi iklim telah berubah akibat pemanasan global. Akibatnya petani sering menghadapi masalah sumberdaya air, terutama pada saat intensitas curah hujan tinggi dengan kurun waktu pendek atau kondisi kering yang berlangsung lama. Untuk menghindari kekeliruan dalam menentukan waktu tanam, perlu dilakukan analisis mengenai waktutanam pada beberapa kondisi ikiim yang berbeda, yang diduga bervariasi antar tempat. Penelitian ini bertujuan untuk mempelajari variasi waktu tanam tanaman padi di Sulawesi, baik waktu tanam yang dominan dilakukan petani maupunberdasarkan kondisi iklim. Awal waktu tanam petani pada musim tanam pertama dianalisis dengan menggunakan data luas tanam level kecamatan periode tahun 2000-2007, sedangkan estimasi waktutanam pada saat curah hujan di bawah normal, normal, maupun di atas normal menggunakan data curah hujan harian runut waktu periode tahun 1980-2007. Awal waktu tanam pada musim tanam pertama yang dilakukan petani di Sulawesi umumnya terjadi pada dasarian pertama dan kedua September (September l/ll) setiap tahunnya; yang sama dengan hasil estimasi pada kondisi basah dan normal walau dengan intensitas yang lebih tinggi. Hal ini menunjukkan bahwa awal waktu tanam di Sulawesi relatif tetap. Tetapi pada kondisi kering petani ebaiknya menanam agak lambat yaitu dasarian III September sampai dengan dasarian pertama Oktober (September Ill/Oktober I) dan secara bertahap dapat dilakukan sampai dengan dasarian pertama dan kedua Januari (Januari l/ll). manfaat informasi estimasiawalwaktu tanam yang tersedia untuk setiap ecamatandiharapkan dapat membantu petani menentukan awal waktu tanam sebelum tiba musim tanam. In determining planting time ofpaddy crop farmers usually use onventional traditions although climatic conditions havechangesdue toglobal warming. As a result, farmers often face water resources problem, especially during a high intensity rainfall in a short period or aprolonged dry period. To avoid inaccuracy in determining planting time, there should bea study ofplanting time on some ofthe different climatic conditions, which are suspected varied among farming sites. This research aims to study the variation in food crops planting times especially in Sulawesi Island, based on both farmer's activities andclimate condition, i.e. wet, normal, anddry years. The existing planting time is determined byusingplanting area data of each sub-district during the period of 2000 to 2007 obtained from Statistics Indonesia. Planting time is considered commencing when 8 percent ofpaddy fields in a sub district have been planted. Planting time estimation on wet, normal, or dry years uses the ten-day rainfall data during the period of 1980 to 2007. The results show that farmer in Sulawesi generally plant rice starting on September in the first and second ten-days (September l/ll) every year. This issimilar to the estimation results on wet and normal years, but with higher intensity. This circumstance shows that early time plant in Sulawesi is relatively constant. Nevertheless in dry condition, farmers have to plant gradually on September Ill/October Iup to Jan l/ll. Information ofinitial planting time ofall sub-districts of Sulawesi is available on cropping calendar map. This information is expected to become the base information in determining planting time of each sub-district to avoid crop failures.

Abstract

Peatland fires are a significant environmental issue, impacting local ecosystems and contributing to global climate change. This study evaluates the Peat Fire Vulnerability Index (PFVI) for sapric and hemic maturity levels under oil palm plantations in Pangkalan Pisang Village, Riau Province. Data on groundwater level, soil moisture, rainfall, and maximum temperature were collected from December 2021 to December 2022. The PFVI, modified from the Keetch-Byram Drought Index (KBDI), was calculated and correlated with these variables. The groundwater level varied from 3 cm to 76 cm below the surface, with an average of 36.23 cm. In sapric blocks, 29% of the groundwater level was less than 40 cm, while 73% were deeper. In hemic blocks, 44% were less than 40 cm, and 56% were deeper. Soil moisture in the top 10 cm layer fluctuated between 32% and 55% (v/v) Results showed significant negative correlations between PFVI and groundwater levels (r = -0.173 to -0.889) and soil moisture (r = -0.835 to -0.808), indicating that lower groundwater levels and soil moisture increase fire risk. High PFVI values in July corresponded with the lowest rainfall (59 mm) and groundwater levels below 40 cm. The study highlights the importance of monitoring hydrometeorological conditions and soil properties to effectively predict and mitigate peatland fires. Our findings are crucial for developing strategies to manage peatland sustainability and reduce fire hazards, especially in tropical regions with prevalent oil palm cultivation.

Abstract

In Indonesia, tidal swampland is potential to be developed into agricultural land uses. Water management is the key success of farming on the tidal swampland. In the tidal swampland of Kalimantan, Indonesia, a fork irrigation system is widely applied in the water channels to supply irrigation water to the land. Besides irrigation, soil physical characteristics play an important role in controlling water availability for crops. The ability of soil to store water will determine the amount of available water that can be taken up by plants. This research aimed to determine the soil physical properties that are related to water availability in the soils from different land uses in a tidal swamp land area applied with a fork irrigation system. The experiment was conducted in dry season 2012, in Belawang, Barito Kuala district, South Kalimantan province. The soil samples were taken from four land uses, namely rice field, rubber plantation, mixed cropping, and unmanaged land. The soil physical properties, namely soil bulk density, particle density, porosity, texture, pF 1, pF 2, pF 2.54, pF 4, water content, total pore space, rapid drainage pores, slow drainage pores, available water, groundwater level were measured. In addition, the mineralogical properties of the soils were measured as well. The results showed that the physical properties of the soils taken from different land use varied, however, the change of the land use did not cause changes in the soil mineralogical properties. The mineralogy of the soils from different land uses are relatively the same, namely: quartz, illite, and chlorite.

Abstract

Carbon stock on peatlands are large and will be easily emitted if the land is opened or drained, therefore the measurements of  carbon stocks and ash content are important to know the amount of emissions and agricultural sustainability in peatlands. This study aimed to determine carbon stock and ash content on peatlands in the Indonesia Climate Change Trust Fund (ICCTF) located in South Kalimantan on the geographic position S. 03°25’52" and E. 114°47’6.5". The experiment consisted of six treatments of ameliorant materials namely; mineral soil, peat fertilizer A, peat fertilizer T, manure, ash, and control.  The results showed that the variation of peat soil properties was very high at this location. Peat thickness ranged from 36-338 cm, and this led to high variations in carbon stocks ranged between 161.8 – 1142.2 Mg ha-1. Besides ash contents of the soil were also highly varied ranged from 3.4 – 28.5%. This natural variation greatly affected the ICCTF study design. Mineral soil treatment had a mean carbon stock (961.3 ± 61.5 Mg ha-1) which was higher and different from other treatments. High ash content was obtained in the ash treatment (18.6 ± 2.5%) and manure (15.7 ± 3.6%).  It is recommended that the analysis of plant responses and greenhouse gas emissions using a single regression analysis and multiple regression with ash content as one of the independent variables are needed.Keywords: Ash content, carbon stock, peatland,  peat thickness[How to Cite: Nurzakiah S, F Agus, and H Syahbuddin. 2013.

Abstract

Salah satu faktor penentu keberhasilan budidaya pertanian di lahan rawa pasang surut adalah waktu tanam.Waktu tanam tanaman pangan terutama padi mempunyai peranan yang sangat penting pada produksi akhir hasilpertanian. Di Indonesia saat ini dikenal 3 Musim Tanam, yaitu musim hujan, antara bulan November-Pebruari,musim kemarau I, antara bulan Maret-Juni; dan musim kemarau II, antara bulan Juli-Oktober. Akan tetapi,dinamika perubahan iklim seperti kekeringan (El Nino) dan kebasahan (La Nina) yang tidak menentu, berimbaspada pergeseran awal dan akhir musim tanam serta berdampak negatif bagi produktivitas tanaman padi. Adanyahal tersebut, analisis tentang waktu tanam padi di lahan rawa pasang surut Pulau Kalimantan perlu dilakukan.Waktu tanam di lahan pasang surut dimulai setelah jumlah air hujan mencukupi untuk melarutkan kadar besi yangada di dalam air. Realisasi tanam di Provinsi Kalimantan Barat umumnya terjadi pada Dasarian 28 (Oktober),Kalimantan Timur pada Dasarian 31 (November), serta Kalimantan Selatan dan Kalimantan Tengah pada Dasarian7 (Maret). Waktu tanam di lahan rawa pasang surut menunjukkan tingkat kekukuhan yang tinggi terhadapperubahan iklim, dimana waktu tanam tidak terlalu berubah selama 10 tahun pada kondisi iklim yang berbeda.Kata kunci: dasarian, luapan, air hujan, kekukuhanABSTRACTOne of the critical factors for agricultural cultivation in tidal swamp land is cropping time. Paddy croppingtime has a very important role in the final production of agricultural cultivation. Currently, there are 3 croppingtime in Indonesia, in the rainy season (November to February), first of dry season (March to June), and second ofdry season, (July to October). However, the climate change dynamic such as drought (El Nino) and wetness (LaNina), shifting the cropping time and resulting a negative impact on the productivity of paddy rice. Therefore, ananalysis of the rice cropping time needs to be done on Kalimantan tidal swampland area. Cropping time in thetidal swampland area began after the amount of rain was sufficient to dissolve the levels of iron in water. In WestKalimantan, the cropping time realization generally occurs in Dasarian 28 (October), while East Kalimantan onDasarian 31 (November), and South Kalimantan and Central Kalimantan on Dasarian 7 (March). Cropping timein tidal swamp land showed a high level of resistance to climate change, in which planting time did not changefor 10 years in different climatic conditions.Key words: decadal, tidal, rainwater, substantiality
