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

Trees of sugar palm (Arenga pinnata Merr.) can grow at an altitude of 0-1400 m above sea level. The best growth of the trees is at an altitude of 500-700 m above sea level. Sugar palm trees also have a wide adaptability to various environmental conditions. The purpose of this research was to determine the morphological characteristicss of sugar palm plants grown at an altitude of 500, 650, and 900 m above sea level so that the kinship relationship can be known. This research was conducted at three altitudes in Lareh Sago Halaban District, Lima Puluh Kota Regency, West Sumatra, namely Nagari Labuah Gunung (altitude 900 m above sea level), Nagari Bukik Sikumpa (altitude 650 m above sea level), and Nagari Tanjung Gadang (altitude 500 m above sea level) from July to August 2023. The method used was a survey with a purposive sampling technique. Identification was carried out on 36 morphological characters, including stems, leaves, fibers, fruits, and seeds. The data obtained were analyzed for their diversity and similarity. The results of the identification and characterization of qualitative and quantitative morphological characters at three different altitudes showed a relatively narrow diversity value. The overall morphological characters of the sugar palm plants were divided into 2 large groups with a coefficient value of 0.72 or 72% similarity distance.

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 present study was conducted in Tebing Tinggi Village, Pulau Punjung Sub-district, Dharmasraya District was motivated by a desire to exploit land resources, especially open access land that was formerly a gold mine by cultivating oil palm plants. The objectives of this study were to determine the characteristics of soil chemical properties, the soil fertility level, and the level of mercury (Hg) contamination in former gold mining land by compared with the soil chemical fertility of oil palm plantations. The research method was a survey by purposive sampling. The Soil sampling for analysis of soil chemical properties was carried out by drilling of 0-40 cm deep with 12 sample points divided into 4 locations, where 3 locations in the former gold mine area that were grouped into three segments, namely segments 1, 2 and 3 and one location was in oil palm land. The parameters of soil chemical properties observed were pH, Al-dd, C-organic, C / N Ratio, N, P, K and Hg (Mercury). The results of this research, shows that the characteristics of soil chemical properties in the former gold mining area have decreased the level of soil fertility, characterized by the very low pH value and C-organic content, ​​so that the nutrients contained in the land are very limited when compared to the soil fertility in oil palm land. This is indicated by the fact that the oil palm land has a high C-organic content and a moderate level of N-total content. The utilization of the land resources of the former gold mine, it is necessary to do land improvementsin terms of soil physically, chemically and biologically.

Abstract

Cameroon and Angola, accession palms oil, were two plants with different flower architectures such as bunch size, bunch length, number of spikelets and flowers, and volatile compounds produced. The difference in flower characteristics was thought to affect the presence of flower-visiting insects in the two palm oil accessions. The study aimed to determine the insects that visit Cameroon and Angola palm oil flower accessions. Insects that visit flowers were collected directly, using yellow pan traps, swing nets, and aspirators. Collected flower-visiting insects were identified as species. Diversity and evenness were calculated using the Shannon diversity index and the Simpsons’ evenness. The total number of flower-visiting insects collected was 2039 individuals. In the Angola accession, 150 individuals were found consisting of 5 orders, 10 families, and 14 species. Insects that visited Cameroon’s accession of palm oil flowers were 1889 individuals consisting of 8 orders, 16 families, and 22 species. Angola accessions’ diversity and evenness index were higher than Cameroon’s, namely 1.50; 1.14 and 1.14; 0.52. Flower-visiting insects that act as pollinators were Elaeidobius kamerunicus, Pyroderces Sp, and Thrips hawaiiensis.
