Abstract

Currently, the government continues to encourage the development of oil palm plantation areas with the aim of boosting domestic economic activity. Nagari Lubuk Karak has a large area of land and has the potential to be developed into plantations, especially oil palm plantations. This regency has a land area of 1056 ha. Therefore, an evaluation of land suitability needs to be carried out in order to know the actual and potential land suitability class recommendations for oil palm plantations in that village. The stages in the research included secondary data collection, pre-survey, main survey and soil analysis in the laboratory. Land suitability classification is done by matching method. From the research results it is known that the limiting factors in the actual land suitability class at the study site were temperature, water availability, nutrient retention, and erosion hazard. After improvements have been made with good land management, the land suitability class can be increased with a potential land suitability class, which was previously classified as S3, increased to S2, and previously classified as S2, can be increased to S1. Thus, to obtain good oil palm growth in this region, it is necessary to improve the limiting factors on each land.

Abstract

Alih fungsi lahan sawah menjadi lahan kelapa sawit dengan status kesuburan tanah yang rendah diduga menyebabkan degredasi lahan. Makrofauna tanah merupakan salah satu tolak ukur yang cukup sensitif pada perubahan lingkungan, sehingga makrofauna tanah sangat cocok sebagai bioindikator kesuburan tanah. Penelitian ini bertujuan untuk mengetahui tingkat keanekaragaman makrofauna tanah dan jenis makrofauna tanah yang mendominasi pada kebun kelapa sawit yang merupakan alih fungsi dari lahan sawah. Penelitian ini dilakukan pada lahan sawah dan lahan yang merupakan alih fungsi sawah menjadi kelapa sawit dengan umur tegakan 7 tahun. Pengamatan makrofauna tanah dilakukan dengan metode hand sorting menggunakan monolith berukuran 30 x 30 cm dengan kedalaman 20 cm. Dari penelitian ini diketahui nilai indeks keanekaragaman pada lahan alih fungsi sawah menjadi kelapa sawit termasuk pada kategori sedang dan indeks kemerataan jenis yang stabil, akan tetapi memiliki nilai kekayaan jenis yang rendah. Ordo yang mendominasi pada lahan alih fungsi sawah menjadi kelapa sawit adalah Hymenoptera sedangkan ordo yang mendominasi pada lahan sawah adalah Opisthopora. Terdapat korelasi yang positif terhadap alih fungsi lahan sawah menjadi kebun kelapa sawit dengan keanekaragaman makrofauna (r=0,383). Dengan demikian dapat diketahui bahwa alih fungsi lahan sawah menjadi kebun kelapa sawit akan meningkatkan keanekaragaman makrofauna tanah.

Abstract

Coffee is one of the plantation commodities that has significant economic value. A factor that needs to be considered in coffee plant cultivation is good planting media composition. This study aims to determine the effect of planting media composition on the growth of robusta coffee seedlings. This study used a Completely Randomized Design with treatments M0= Soil: 100%, M1= Soil: 50% + Coffee Husk Compost: 25% + Rice Husk: 25%, M2= Soil: 25% + Coffee Husk Compost: 50% + Rice Husk: 25%, M3= Soil: 25% + Coffee Husk Compost: 25% + Rice Husk: 50%. The analyses conducted were compost analysis and initial and post-incubation soil analysis. Observation data were analyzed using the F test followed by DNMRT at the 5% level. The research results show that the provision of coffee husk compost and rice husks affects the chemical properties of the soil and the growth of coffee seedlings. The planting media composition of Soil: 25% + Coffee Husk Compost: 50% + Rice Husk: 25% proved to increase the pH of the planting media from 5.5 to 6.6, increase in total N-value from 0.2% to 0.5%, available P from 18.6 ppm to 38.5 ppm and the soil CEC from 7.6 me/100g to 36.6 me/100g. This planting media composition also makes it possible to enhance the growth of robusta coffee seedlings in plant height, stem diameter, number of leaves, leaf width, and root volume. Thus, this planting media composition is a suitable medium for the growth of robusta coffee seedlings.

Abstract

Limbah tandan kosong kelapa sawit (TKKS) merupakan limbah padat yang dihasilkan dari sisa pengolahan di pabrik kelapa sawit. Seiring dengan bertambahnya luas lahan kebun kelapa sawit menyebabkan jumlah limbah TKKS semakin meningkat. Meningkatnya jumlah limbah ini secara terus menerus akan menyebabkan terjadinya pencemaran lingkungan, seperti polusi udara akibat bau yang tidak sedap. Akan tetapi, limbah TKKS dapat memberikan manfaat jika diolah dengan baik. Salah satu cara yang bisa dilakukan dalam pengolahan limbah TKKS adalah dengan merubah limbah tersebut menjadi biochar. Biochar dari TKKS dapat dimanfaatkan untuk memperbaiki kualitas lahan di kebun kelapa sawit rakyat. Kegiatan pengabdian masyarakat yang terintegrasi dengan mahasiswa Kuliah Kerja Nyata (KKN) ini bertujuan untuk memberikan pelatihan cara membuat biochar dari limbah TKKS kepada kelompok tani Semoga Jaya yang berada di Kenagarian Koto Beringin Kecamatan Tiumang Kabupaten Dharmasraya. Melalui pelatihan ini, diharapkan petani dapat mengelola limbah tersebut secara mandiri dan berkelanjutan, serta memanfaatkannya dengan baik untuk perbaikan kualitas lahan kelapa sawit rakyat. Kegiatan pelatihan diikuti dengan antusias oleh petani, hal ini dapat dilihat dari banyaknya pertanyaan yang muncul selama kegiatan pelatihan berlangsung. Hal ini menunjukkan bahwa para petani sangat tertarik untuk menerima ilmu yang disampaikan, dan ingin mencoba  dan mengaplikasikan pembuatan biochar ini pada kebun kelapa sawitnya masing-masing.

Abstract

The optimal utilization of oil palm empty fruit bunch (OPEFB) waste holds significant potential for biomass bioconversion via slow pyrolysis, presenting a promising alternative for producing high-quality biochar as a soil ameliorant. This study investigates the effects of slow pyrolysis temperatures (≤ 300 °C) on the physicochemical properties of biochar derived from OPEFB and evaluates its efficacy as a soil ameliorant. This study utilized a completely randomized design (CRD) with three replications across two experiments. The first experiment assessed the effect of slow pyrolysis temperature on the quality of biochar derived from OPEFB, with treatments set at four temperatures (150, 200, 250, and 300 °C) levels. The second experiment evaluated the impact of the selected biochar on the surface charge of oil palm plantation soil, applying biochar at five different doses (0, 20, 40, 60, and 80 tons ha-¹). The potential temperature of 200 °C in slow pyrolysis had a significant effect on the quality of biochar from OPEFB with a yield ratio of 27.84% char; proximate (91.95% volatile matter and 0.81% fixed carbon), cation exchange capacity (CEC) [167.73 cmol(+) kg-1], and macro and micronutrients (e.g., C, N, P, K, Ca, Si, Fe, Cu, Zn, and Mn). The potential of O-H, N-H, C-H, and C=O functional groups of biochar from OPEFB for nutrient availability and absorption efficiency proven by the effect of 40 tons ha-1 biochar from OPEFB which significantly increased 80% of soil surface charge [pH by 0.80; organic matter (OM) composition by 19.8%, CEC by 11 cmol(+) kg-1] and nutrients [0.93% C; 0.04% N; 17.57 ppm P2O5; 0.65 cmol(+) kg-1 K] on Inceptisols.

Abstract

Indonesia needs to diversify cane sugar into brown sugar to reduce imports of cane sugar. Excessive consumption of cane sugar is one of the causes of the increase in diabetes mellitus sufferers. The sugar palm plant as a producer of brown sugar has the potential to be developed as a substitute for cane sugar. Identification of sugar palm plants is carried out to determine genetic diversity. High genetic diversity also has high adaptability. This research aims to determine differences in the morphological characteristics of sugar palm plants based on different altitudes and identify the level of uniformity of morphological characteristics in sugar palm plants. The results of these observations are used as initial data to determine the parent tree that will be used as propagation material. The research was conducted in North Lintau Buo District, Tanah Datar Regency, West Sumatra from September to October 2024. Sampling locations were taken based on different altitudes with three plant samples per altitude until nine plant accessions were obtained. The research results showed that the quantitative and qualitative characters of sugar palm plants had relatively narrow phenotypic variability values. The kinship analysis of sugar palm plants has a level of similarity with a coefficient value of 10.13 – 80.39%. The closest relationship distance is shown in accession 8 and accession 9, with a similarity level of 80.39%. Meanwhile, accession 4 has a distant relationship with accessions 1, 3, 2, 7, 8, 9, 6, and 5 with a similarity level of only 10.13%. PCA analysis shows that accession 4 is different from other accessions based on the characteristics of bark color, frond shape, petiole shape, and build leaflets.

Abstract

The area of oil palm plantations in Dharmasraya Regency is not in line with the amount of production obtained by farmers. This is due to the large number of parthenocarpic fruits caused by the few pollinators and male flowers, so the pollination process in oil palm plantations is not optimal. This activity aims to train farmers in Koto Beringin Village, Tiumang District. The activity method is carried out through counseling and demonstration plots on applying hatch & carry techniques for Elaeidobius kamerunicus to improve the pollination process so that oil palm production can increase. In this activity, farmers are expected to be able to produce products in the form of oil palm pollen and Elaeidobius kamerunicus breeding cages. From the activities that have been carried out, it is known that farmers' knowledge of hatch & carry techniques for Elaeidobius kamerunicus is still very minimal. Through counseling and demonstration plot activities, farmers have been able to breed Elaeidobius kamerunicus and collect oil palm pollen. From the results of observations in people's oil palm fields, it is known that after the application of the Hatch & Carry technique was carried out, there was an increase in the number of Elaeidobius kamerunicus pollinators from 524 individuals/Ha to 21,137 individuals/Ha and will continue to increase if the application of the Hatch & Carry technique continues to be carried out. If farmers apply the hatch & carry technique of Elaeidobius kamerunicus correctly, it can increase the number of pollinators that play a role in pollination.
