Abstract

DOI:10.17014/ijog.9.2.195-208The most potential soil order in Indonesia is dominated by Inceptisols, whereas the topography combined with a climatic factor are the main factors to regulate pedogenetic process. This research was intended to determine the pedogenetic process and soil development on various terrain positions at the southeast toposequence of Mount Manglayang areas that have hilly topography. The researched area was 28.83 ha. Based on those conditions, this research aims to study the pedogenetic process and soil development in the southeast slope toposequence of Mount Manglayang, the relationship between the physical, chemical, and mineralogical soil properties, the soil classification to family level based on soil taxonomy, National Soil Classification, and FAO soil classification systems. This research used survey, descriptive, and comparative methods. The result showed that the pedogenetic processes identified were the formation of B horizon through clay accumulation, soil colour, and soil structure development, and the formation of amorphous kaolinite and halloysite minerals. Based on soil taxonomy, the soil were classified as Fluventic Humudepts, coarse-loamy, kaolinitic, isohyperthermic at the upper slope and Fluventic Dystrudepts, fineloamy, kaolinitic, isohyperthermic at the middle and lower slopes. According to National Soil Classification, the soil is Humic Cambisol at the upper slope, Distric Cambisol at the middle slope, and Cromic Cambisol at the lower slope. FAO classified the soil as Umbric Cambisols at the upper slope and Dystric Cambisols at the middle and lower slopes.

Abstract

ABSTRACT The current implementation of land suitability classification of Cocoa is based on the national standard of growing plant. Therefore the implementation of the land use at the specific location was not acceptable. It is important to evaluate the land suitability  of  the  cocoa  growing  areas.  This  study  was  conducted  at  Kolaka  Regency Southeast Sulawesi Province. This research was performed using a survey method based on the observation unit. Which is consist of 93 observation units.   The climate, soil and environment observations were following the Soil and Agroclimate Research Centre ( PPTA, 1993); Department of Agriculture (DEPTAN, 1993 dan 2003) and the Indonesian Coffee and Cocoa  Research  Centre  (PPKKI,  2008).  The  analysis  of  land  suitability  is  base  on  the threshold factor using the mínimum. The results showed that the land suitability of the cocoa growing areas according to  PPTA dan DEPTAN (1993) were classification full into 76.34% marginal suitable (S3), 12.90% currently not suitable (N1) and 10,75% was permanently not suitable (N2). On the other had based on the DEPTAN (2003) the cocoa growing areas were 83.87% S3 and 16.13% not suitable (N). While according to the PPKKI  (2008) the S3 was 63.44% and the N was 36.56%. Key word: land suitability classification and cocoa

Abstract

Climate is an important factor which influences the growth and productivity of oil palm. The current oil palm cultivation system is vulnerable to climate change. For example, there was a decline in global oil palm production in 2015 due to ENSO, particularly affecting Southeast Asia. Extreme drought causes oil palm plants to experience water stress, while forest fires due to drought inhibit the photosynthesis process. A comprehensive study of the Systematic Literature Review was carried out using bibliometric analysis, systematic review and Meta-Analysis (PRISMA) methods, using the search engines Scopus and ScienceDirect with the keywords “palm AND oil AND production AND climate AND change”, “impact AND climate AND change AND coconut palm AND oil”, “palm AND oil AND adaptation AND climate AND change”, “palm AND oil AND mitigation AND climate AND change”. A thorough scientific literature review obtained 1331 papers from Scopus and ScienceDirect. Out of these, only 26 articles were selected for further examination. Based on the literature, there are several strategies for increasing oil palm productivity in the era of climate change. These strategies can be done through agronomic management, providing fertilizer from oil palm biomass, and maintaining irrigation for water availability. This literature study provides recommendations for strategies for increasing oil palm productivity in the face of climate change.

Abstract

Kopi Arabika adalah komoditas ekspor perkebunan yang berperan penting bagi perekonomian Indonesia. Namun, produksi kopi arabika ini masih tergolong rendah yaitu 800 kg/ha. Salah satu sentra kopi Arabika di Jawa Barat berada pada daerah aktivitas geothermal Pembangit Listrik Tenaga Panas Bumi (PLTP) Kamojang. Penelitian ini bertujuan untuk mengetahui dampak uap dari aktivitas geothermal terhadap iklim mikro dan produksi kopi Arabika. Penelitian dilakukan dengan pengamatan parameter iklim yaitu suhu udara, kelembapan udara, dan intensitas cahaya matahari pada lima lokasi berdasarkan jarak berbeda dari pusat geothermal PLTP Kamojang yaitu Lokasi 1 (0-250 m), Lokasi 2 (250-500 m), Lokasi 3 (500-750 m), Lokasi 4 (750-1.000 m) dan Lokasi 5 sebagai lokasi kontrol (kira-kira berjarak 3 km) yang memiliki karakteristik lahan yang sama. Hasil penelitian menunjukkan bahwa uap panas bumi berpengaruh terhadap kondisi iklim mikro yaitu menurunkan suhu udara sebesar 8,8, 8,3, 6,9 dan 1,8% dibandingkan kontrol, menurunkan intensitas cahaya matahari sebesar 62, 50, 36 dan 19% dibandingkan kontrol serta menaikkan kelembapan udara sebesar 11, 5, 4 dan 1% dibandingkan kontrol untuk masing-masing Lokasi 1-4. Kondisi iklim mikro tersebut berpengaruh terhadap penurunan produksi kopi Arabika (kg/ha) pada Lokasi 1, 2 dan 3 masing-masing sebesar 33, 19 dan 13% dengan radius kurang dari 750 m dari pusat geothermal PLTP Kamojang. Berkurangnya intensitas matahari berdampak pada penurunan suhu udara, dan pada gilirannya kelembaban relatif meningkat. Suhu yang lebih rendah dapat memperlambat pertumbuhan tanaman kopi. Kelembaban yang tinggi juga dapat meningkatkan risiko kejadian penyakit pada tanaman kopi.
