“…Hujan umumnya terjadi pada sore dan malam hari, hal ini sangat menguntungkan untuk budidaya kelapa sawit. Hasil perhitungan menunjukkan bahwa lokasi penelitian mengalami defisit air pada tahun 2014-2017 berturut-turut sebesar 214 mm, 251 mm, 63 mm, dan 0 mm, yang berarti masih sesuai (favourable) untuk pengembangan tanaman kelapa sawit (Rhebergen et al, 2016).…”

Pertumbuhan dan perkembangan tanaman bergantung pada pengaruh kondisi lingkungan (termasuk di dalamnya suhu udara). Pengaruh kondisi lingkungan terhadap periode fase-fase perkembangan tanaman dikenal dengan istilah fenologi. Konsep umum yang digunakan untuk mengetahui pengaruh suhu terhadap kondisi fenologi secara kuantitatif adalah thermal units. Penelitian ini bertujuan untuk mengamati karakter fenologi perkembangan tandan buah segar pada delapan varietas yang dirilis Pusat Penelitian Kelapa Sawit (PPKS) berdasarkan konsep thermal units. Penelitian ini juga membahas implikasi dari karakteristik masing-masing varietas terhadap pemilihan varietas kelapa sawit spesifik lokasi agroklimat. Penelitian dilakukan di Demonstrasi Plot (Demplot) Varietas Kebun Benih Adolina PT Perkebunan Nusantara IV, Kabupaten Serdang Bedagai, Sumatera Utara dengan ketinggian 10 mdpl pada 11 September 2014 – 30 Juni 2018. Hasil penelitian menunjukkan bahwa kemunculan daun pertama hingga tandan siap dipanen pada varietas DxP Avros, DyP Dumpy, DxP LaMe, DxP Langkat, DxP PPKS 540, DxP PPKS 718, DxP Simalungun serta DxP Yangambi memerlukan jumlah thermal units (oC hari) dan durasi (hari) berturut-turut adalah 5.785 dan 457; 5.756 dan 454; 6.050 dan 476; 5.903 dan 467; 5.775 dan 452; 6.164 dan 484; 6.105 dan 478; serta 6.084 dan 479. Varietas DxP PPKS 540 cenderung lebih sesuai untuk digunakan pada wilayah dengan kondisi suhu rata-rata harian yang rendah (18-23oC). Pada wilayah dengan suhu rata-rata 24-32oC, semua varietas kelapa sawit yang dirilis PPKS akan dapat tumbuh dengan optimal. Sementara itu, khusus untuk wilayah dengan suhu rata-rata 30-32oC, sebaiknya dipilih varietas yang memiliki potensi jumlah tandan yang lebih banyak seperti DxP Avros, DxP LaMe, DxP Langkat, DxP PPKS 540, DxP Simalungun dan DxP Yangambi.

Plantations development in KPH UPTD Boalemo Unit V area should be supported by community readiness and land suitability. This study analyzed the potential of masoyi plantations in the UPTD KPH Boalemo Gorontalo Unit V based on community readiness and land suitability. The level of community readiness was measured through in-depth interviews with key informants. Land suitability analysis was carried out using species matching method on the plant growth requirements of masoyi. Land characteristics were obtained from secondary data, direct field measurements, and soil analysis. The results showed: 1) community readiness is at level seven to nine; Ayuhulalo Village, Bendungan Village, Botumoito Village, and Rumbia Village have the highest community readiness, 2) land suitability is divided into: suitable 15.93%, moderately suitable 53.82%, and 24% unsuitable, 3) an area of 22,644 ha have the potential for development of masoyi plantation because it has a high level of community readiness and land suitabiliy level at moderately suitable, 4) an area of 7,041 ha is a priority area for the development of masoyi because it has a high level of community readiness and land suitability class at suitable, 5) Bendungan Village and Butomoito Village have the best community readiness and land suitability, 6) production forest area is dominated by marginally suitable land; land improvement/ manipulation is needed towards the limiting factors to support successful planting.

“…Sustainable production projects should also sensitize small-scale plantations to desist from encroaching on river banks and swampy areas to cultivate oil palm. A study by Rhebergen et al (2016) also found opportunities for large-scale oil palm plantation development is limited, however, and recommended smallholder production or yield intensification on land already planted as a feasible strategy for oil palm expansion in Ghana. This could also reduce the requirement for further land clearance for new plantations to meet the growing demand for palm oil.…”

“…The high demand for palm oil and it products have resulted in a rapid expansion of oil palm cultivation across the world. Due to the lack of land availability in Southeast Asia, large expansion of the oil palm industry is expected in sub-Saharan Africa, particularly in West-Africa where land with suitable agroecological conditions is available (Rhebergen et al, 2016). The oil palm industry in Ghana has developed over the last two decades into an important industry in the agricultural sector of the economy (Kabutey et al, 2013).…”

The oil palm industry has many positive benefits, particularly as a key source of livelihoods for rural dwellers, but it also has negative impacts on the society and environment. For instance, poorly planned oil palm cultivation can increase the rate of natural forest loss, and contribute to unfair labour conditions on plantations and processing mills. It is therefore important for sustainable oil palm project initiators to understand the environmental and social effects of the industry, to be able to design appropriate interventions. Using a survey method, questionnaires were administered to different stakeholders in selected oil palm plantations and processing mills to generate both qualitative and quantitative data for assessing the social and environmental impacts of the industry. The environmental and social impact assessment was done within the framework and guidelines of the Roundtable on Sustainable Palm Oil (RSPO). The assessment also applied a holistic approach by diagnosing the direct, indirect and sector-wide cumulative impacts. It was found that, in most cases, the social and environmental indicators assessed from the respondents do not comply with the guidelines of national legislation and the Ghana interpretation of the RSPO principles. It is prudent for sustainable oil palm projects to provide opportunities for plantation and mills owners and workers to acquire, and share knowledge on the effects of their activities on the society and environment. Project interventions must be formulated to mitigate negative impacts of the activities of production and processing to ensure sustainability of the oil palm industry.
