“…Sistem sertifikasi yang banyak digunakan untuk produksi kopi antara lain Fair Trade, 4C Common Code, (3) Rainforest Alliance, Organic, dan Utz Certification. Agroekosistem kopi bernaungan dadap atau gamal memberikan nilai keberlanjutan yang tinggi baik dari segi usahatani (Evizal et al, 2010) maupun dari segi agroekosistem.…”

Agronomy not only studies cultivation technology and agricultural production, but also examines the application of agricultural concepts and systems that continue to develop. The rapid and fundamental transformation of the agricultural system called the green revolution is based on the use of high inputs to increase agricultural production. The use of inputs that are not environmentally friendly and the emergence of environmental awareness encourages the transformation of agricultural systems into environmentally friendly agriculture such as ecofarming, organic farming, alternative farming, sustainable agriculture and regenerative agriculture. This article reviews the concepts of sustainable agriculture, degenerative agriculture, regenerative agriculture and the practice of implementing regenerative agriculture on coffee plantations. Degenerative agriculture is an agricultural practice that causes productivity to continue to decline as a result of a decrease in the carrying capacity of the agroecosystem, including soil, plants and other flora, fauna, microbes, climate and society. Sustainable agriculture aims to maintain a desired or improved level of ecosystem function, while regenerative agriculture aims to regenerate, renew, and further improve soil function and ecosystem capabilities in an ever-increasing process. The ecological pillars of regenerative agriculture include (1) soil health, (2) biodiversity, and (3) livestock-crop integration. Regenerative coffee plantation practices include the use of superior clones or varieties, grafting, planting shade trees and mixed crops, and livestock integration.Keywords : Biodiversity, degenerative, integrated, sustainable, regenerative agriculture

“…Perkebunan sawit mencapai luas 14,3 juta ha pada 2018, terdiri dari perkebunan swata 51,4%, perkebunan rakyat 42,3% dan sisanya perkebunan negara. Produktivitas yang tinggi dicapai oleh perkebunan swasta dengan produktivitas aktual 19,7 ton TBS per hektar atau 62% dari potensi produksi (Evizal et al 2021). Meskipun demikian, budidaya tanaman tahunan seperti sawit menghadapi permasalahan yang lebih rumit dan beragam dibandingkan dengan tanaman semusim sebagai konsekuensi dari investasi, budidaya, produksi, biaya, dan penerimaan usahatani yang dilakukan selama periode yang panjang.…”

Oil palm is Indonesia's mainstay plantation commodity as a source of income for farmers and plantation companies and a source of foreign exchange. Oil palm is a plant with the highest productivity of vegetable oil with a production age beyond 30 years. To evaluate the productivity of old plants of oil palm, a comparative study was carried out based on the number of different populations per unit area of land. The calculation of oil palm plant production in the form of fresh fruit bunches (FFB) was carried out in old plant population areas with different population numbers per hectare due to population reduction after the productive age of the plants had passed. The calculation results show that the productivity of old oil palm plants (34 and 35 years) is influenced by the number of populations per hectare. Oil palms aged 35 years with higher productivity per unit area were 115 and 118 trees per hectare, but the areas with 100 and 115 populations of oil palms per hectare produced a higher weight of FFB per bunch. For oil palm plantations aged 34 years, populations with higher productivity were 100 and 118 trees per hectare, but a higher average weight of FFB per bunch was found in the areas with 85 and 100 populations per hectare.

“…A valid method for calculating water balance can provide information on water availability and accurate production predictions. The previous study did not consider the value of available water content (AWC) and critical deficit of each soil type in calculating water balance in oil palm plantations (Afandi et al, 2022;Ardiyanto et al, 2021;Darlan et al, 2016;Evizal et al, 2021;Kaeng et al, 2017;Monzon et al, 2022). Most of the AWC values used are the same, which refers to Ultisols, even though the area has different soil types.…”

The same rainfall can cause different degrees of water stress depending on soil type, so the production response shown by plants can be different. This study is essential for growers, especially in predicting oil palm production based on water deficit for each soil type. The study was conducted on oil palm plantations in Central Kalimantan, Indonesia, with four soil types in 1,446.15 ha (40 blocks). The source of data collected from oil palm plantations included bunch number, average bunch weight, rainfall, and soil physical and chemical properties for the last 15 years (2007 - 2021). This experimental study used a two-stage cluster sampling method. The results showed that the best productivity, bunch number, and average bunch weight were found on Ultisols. The four soil types tested showed the same annual production distribution dynamic, but the response rate from each soil type showed differences. Entisols and Spodosols were more prone to drought stress due to water deficit than Ultisols and Histosols because of the differences in soil texture. Water deficit causes a decrease in oil palm productivity by 5 - 22% in the first year (Ultisols 12 - 22%; Entisols 12 - 22%; Spodosols 7 - 19%; Histosols 5 - 15%) and 1 - 8% in the second year (Ultisols 3 - 7%; Entisols 2 - 4%; Spodosols 5 - 8%; Histosols 1 - 5%) compared to previous years production. A decrease in oil palm productivity occurs at 3 - 5 months (bunch failure phase), 1 year (abortion sensitive phase), and 2 - 2.5 years (sex differentiation phase) after a water deficit appears.
