“…Petani dan perusahaan perkebunan sawit dihadapkan kepada permasalahan ketika tanaman memasuki tahap penurunan produksi; selaku produsen harus memutuskan kapan dan berapa persen dari jumlah tanaman yang harus diremajakan untuk memaksimalkan arus pendapatan dari waktu ke waktu (Mariyah et al 2018) Kondisi tanaman yang sudah tua dan tidak produktif menyebabkan produktivitas menjadi rendah, output menjadi stagnan dan mempengaruhi suplai industri kelapa sawit (Wahid dan Simeh, 2010). Peremajaan sebagai upaya menggantikan tanaman tua dengan tanaman baru dan merupakan praktek manajemen tanaman tahunan untuk memaksimumkan dan menstabilkan pendapatan (Kotagama et al 2013) harus dilakukan dan direncanakan secara tepat.…”

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.

“…It is worth noting that we distributed the questionnaire to over 1000 respondents; however, we received a response from only 122 participants. This is because the willingness of farmers to participate in research in Oman has been consistently low, a fact that has been highlighted by several previous studies (Al-Mezeini et al, 2020;Kotagama et al, 2014;Zekri et al, 2007). Furthermore, farm visitation allowed direct observation of the farming practices and management (e.g.…”

Soil Use and Management

Soil salinity threatens agricultural sustainability globally and is a significant challenge in Oman. Previous studies in Oman focused on examining the causality and spatiotemporal variation of groundwater and soil salinity, neglecting farmers' perceptions and attitudes toward salinity management. Therefore, this study evaluates (i) perceptions and attitudes of landowners and farmers toward soil salinity and its management, and (ii) determinants of willingness to use elemental sulfur to alleviate soil salinity in Oman. A questionnaire survey (122 responses) assessed perceptions, attitudes, and knowledge using Likert scales and qualitative questions. Binary Logistic Regression analyzed determinants of willingness to use elemental sulfur. Results reveal variations in perceptions, attitudes, knowledge, and management practices. Most of the respondents were aware of adequate nutrient and water requirements for crops (P<0.05). Respondents rely on social media (38.5%), fellow farmers (32.1%), and personal experiences (11.5%) for knowledge acquisition about soil salinity management. Half of the respondents did not monitor soil salinity, while the other half relied primarily on visual observation. A substantial number (62.6%) of the respondents did not implement any techniques to alleviate soil salinity, while among those who acted, a majority preferred cultivating date palms (55%) or fodders (29.4%). Awareness of the national salinity management strategy and commercial products is lacking. However, when introduced to elemental sulfur as a soil amendment for salinity, 74.8% of the respondents demonstrated a willingness to utilize it. Most (82.4%) preferred elemental sulfur products within the lowest price range. Being a full‐time farmer, owning a farm, awareness of the national strategy, and low‐price preferences were positive determinants, while <1 year farming experience was negative determinant to willingness to use elemental sulfur. These findings inform future research on socio‐economic perceptions of salinity in Oman, the Gulf region, and similar arid areas facing food production limitations.

“…Menurut Setyamidjaja (2006), teknik budidaya kelapa sawit terdiri dari beberapa tahapan, antara lain: pembibitan, pembukaan lahan, rancangan kebun, penanaman, tanaman penutup tanah, pemeliharaan tanaman belum menghasilkan (TBM), pemeliharaan tanaman menghasilkan (TM), dan peremajaan. Menurut (Kotagama et al 2013) peremajaan kelapa sawit merupakan praktek budidaya dalam pengelolaan tanaman tahunan untuk memaksimalkan dan menstabilkan pendapatan antar waktu. Sedangkan peremajaan dini diartikan sebagai penggantian tanaman sawit muda berumur 10-25 tahun milik petani atau perkebunan rakyat yang menghadapi masalah produktivitas rendah < 10 ton per hektar akibat kesalahan bibit, dengan tanaman kelapa sawit yang baru (Arsjad 2017).…”

The decision to replant oil palm is a complex decision for smallholder farmers in Teluk Merbau Village who are members of the Tunas Muda KUD, Siak Regency, Riau Province. Oil palm replanting needs to be done because the age of oil palm plantations for KUD Tunas Muda farmers on average has reached a planting age of >30 years with a production yield of only 1.47 tons per hectare per year. The implementation of oil palm replanting is carried out through the People's Palm Oil Rejuvenation (PSR) program. This research aims to examine the applicable regulations regarding the implementation of oil palm replanting at KUD Tunas Muda and analyze the perception of smallholder farmers on the implementation of oil palm replanting. Data were analyzed using gap analysis and qualitative descriptive analysis. Adjusted to the Director General of Plantation Decree No.29/KPTS/KB.120/3/2017 concerning guidelines for the implementation PSR. The results of the analysis of the perception farmers indicate input aspects, financial aspects and institutional aspects that influence farmers' decisions in the implementation of oil palm rejuvenation. The stakeholder involvement aspect consists of 3 components: related stakeholders, stakeholder rights and stakeholder obligations. The implementation PSR program is very helpful and this program can only be accepted by oil palm farmers who are members of the Tunas Muda KUD membership.
