Abstract

This research aim was toevaluate land suitability for dragon fruit plantation in  Maku village, Dolo sub district, Sigi Regency, Central Sulawesi Province. Seven land units were evaluated for their suitability. Survey was conducted in seven land units for observation on soil drainage, slope, stones, and root depth. Undisturbed and disturbed soil sample were taken from each land unit for physical and chemical analyses in the Soil Laboratory of Agriculture Faculty Tadulako University.  Of the seven land units, one land unit was classified as actual N1 (currently not suitable), another one land unit as S2 (moderately suitable) whereas the other five land units were categorized as actual S3(marginally suitable). The limiting factorsconsisted of texture, water, and soil pH. By correcting all the limiting factors existing in all land units, the actual classes of N1, S3 and S2 can be changed into the potential classes of S3, S2, and S1, respectively.

Abstract

The objective of this research was to assess the potassium nutrient status in lowland rice fields. The study was conducted in Ranteleda Village, Palolo Sub District, Sigi District, from January to June 2021. Soil samples was analyzed at the Soil Science Unit Laboratory, Faculty of Agriculture, Tadulako University, Palu. A survey method was employed in this research, and a purposive sampling technique was used to determine soil sampling locations. The soil sampling was carried out at two different depths: 0-20 cm and 20-40 cm. Each sampling point was considered as a replicate. The results revealed that soil K-Total content ranged from 38.54 to 36.62 mg/100g (moderate). The soil pH was moderately acidic, with a range of 6.23 to 5.08. The organic carbon content (C-organic) ranged from 3.31% to 2.58% (moderate). The soil CEC was found to be in the range of 13.19 to 10.54 me/100g (low). The exchangeable bases showed very low K (0.11 me/100g), very low Ca (1.16 me/100g), moderate Mg (1.15me/100g), and a moderate Na (0.31 me/100g).

Abstract

This study aimed to determine the distribution of organic matter status as a basis for soil fertility management across different land uses in Bakubakulu Village, Palolo Subdistrict, Sigi District. Soil analysis was conducted at the Soil Science Laboratory Unit, Faculty of Agriculture, Tadulako University, from July to August 2022. Soil samples were collected from various land use types, including primary dry land forest, secondary dry land forest, mixed dry land agriculture, and bushes. A total of 16 soil samples were taken and composited into eight samples. The analysis revealed that land unit (LU) 2.2 had the highest organic matter status (3.75%) and C-Organic content (2.18%), meeting moderate criteria. The results also showed that soil pH was highest in LU 1.2 (6.67), while N-total was highest in LU 3.2 (0.31%). Soil texture varied across the samples, with different land use types exhibiting distinct textures, ranging from sandy loam to loamy sand. The findings of this study provide valuable insights for optimizing soil fertility management strategies across different land uses in the region.

Abstract

Penelitian ini bertujuan untuk mengetahui sebaran hara fosfor (P) di lahan kakao pada kedalaman yang berbeda di Istalasi Penelitian dan Pengkajian Teknologi Pertanian Sidondo III. Penelitian dilaksanakaan di Lahan kakao di Desa Sidondo III Kecamatan Sigi Biromaru Kabupaten Sigi. Analisis tanah dilakukan di Laboratorium Ilmu Tanah sekitar 4-5 bulan, Fakultas Pertanian Universitas Tadulako. Hasil penelitian menunjukkan sebaran P-total pada kedalaman berbeda nilai tertinggi diperoleh pada kedalaman 21-60 cm dengan nilai 64,75 mg/100 g dan terendah pada kedalaman 61-100 cm dengan nilai 54,49 mg/100 g berada pada kriteria tinggi sampai sangat tinggi.

Abstract

Corn is a very important food ingredient after rice. Central Sulawesi corn production data is in the form of time series data which every year in certain months increases or decreases in production. Therefore, the method that can be used for forecasting is the winter multiplicative method. This study aims to build the best model for forecasting corn production in Central Sulawesi using the winter multiplicative method. The results of this study are used to explore corn production for the next period. Modeling is done by selecting the best combination of parameters and the best combination of model parameters is obtained with a mean absolute percentage error (MAPE) of 18% with a value of α = 0,5; γ = 0,1; and β = 0,1. The data plot of the forecasted corn production shows fluctuations which indicate seasonal factors and trends in it

Abstract

Tanaman Padi (Oryza sativa L.) merupakan bahan pangan strategis di Indonesia diolah menjadi beras sebagai makanan pokok. Di dalam tanah, khusunya pada daerah rhizosfer suatu tanaman umumnya terdapat berbagai macam mikroorganisme yang hidup dan menguntungkan bagi pertumbuhan suatu tanaman. Rhizosfer merupakan daerah perakaran yang menyediakan berbagai bahan organik yang dapat merangsang pertumbuhan mikroba sehingga rhizosfer adalah habitat yang sangat baik bagi pertumbuhan mikroba. Tujuan dari penelitian ini adalah untuk mengetahui Beberapa karakteristik jamur rhizosfer tanah yang terdapat pada tanaman padi gogo di Desa Ampera Kecamatan Palolo Kabupaten Sigi. Metode yang digunakan dalam penelitian ini adalah metode deskriptif eksploratif dengan cara purposive sampling untuk pengambilan sampel tanah yaitu pengambilan sampel tanah yang lokasinya ditentukan berdasarkan pertimbangan peneliti. Pelaksanaannya dilakukan dengan survei lapangan dengan mengambil 5 Sampel tanah. Penelitian ini dilakukan di dua tempat yang pertama pengambilan sampel tanah di Desa Ampera Kecamatan Palolo, Kabupaten Sigi, lalu yang kedua adalah analisis tanah yang dilaksanakan di Laboratorium Ilmu Tanah, dan Laboratorium Hama Penyakit Fakultas Pertanian, Universitas Tadulako, Palu. Penelitian ini dilaksanakan pada bulan Desember 2024 sampai Februari 2025. Hasil analisis pH tanah pada H2O pada jenis sampel PTL, Delima, PB, dan BU berada pada kisaran agak masam dan pada sampel PPB pada kisaran masam, dan pada analisis pH tanah KCL yaitu pada jenis sampel PTL, Delima, BU berada pada kisaran masam, sedangkan PPB sangat masam dan PB agak masam. Hasil C-Organik tanah pada lima sampel tersebut memiliki kriteria sangat rendah hal ini disebabkan beberapa faktor yaitu pengolahan tanah yang tidak tepat. Hasil isolasi jamur rhizosfer tanah pada Padi Gogo terdapat 469 jumlah koloni dari sampel keseluruhan dan mempunyai karakteristik yang berbeda-beda. Berdasarkan pengamatan secara makroskopis dugaan sementara ada 2 genus yang terdapat pada 5 sampel tersebut yaitu Genus Penicillium, Aspergillus dan Trichoderma.

Abstract

Stunting or chronic malnutrition is a nutritional problem due to a lack of nutritional intake from food that lasts for a long time. Loru Village is one of the villages located in the Biromaru Health Center Working Area, Sigi Regency, Central Sulawesi Province, where Sigi Regency is the district with the highest stunting cases in Central Sulawesi Province and Biromaru Health Center is the Health Center with the highest stunting cases in Sigi Regency. In addition, Loru Village is one of the pumpkin producing areas in Central Sulawesi Province. So through this PKM activity, the partners or cadres of the integrated health post who will be empowered are 20 people, then this group will become a role model for the community. The goal for partners is to innovate Additional Food products in the form of pumpkin-based biscuits to prevent and control stunting and also improve community welfare, The results of this activity are an increase in knowledge and skills for partner groups, both in terms of increasing knowledge about stunting and its impacts, increasing knowledge about the benefits of pumpkin as additional food for toddlers, increasing skills in making biscuits from pumpkin and increasing skills about sustainable food gardens.
