Abstract

Persepsi dapat mempengaruhi petani dalam mengambil keputusan pada kegiatan usahataninya.  Persepsi yang keliru atau negatif terhadap suatu produk akan menyebabkan sikap yang negatif, perilaku yang kurang bagus terhadap produk tersebut dan tentunya akan mempengaruhi pada keputusan untuk menggunakan atau tidak menggunakan produk tersebut.  Oleh karena itu, sangatlah penting untuk menganalisis persepsi tersebut. Penelitian ini bertujuan untuk menganalisis persepsi petani terhadap pupuk organik. Sampel dalam penelitian ini berjumlah 258 orang petani padi yang ada di Kecamatan Walenrang Utara Kabupaten Luwu. Hasil penelitian memperlihatkan bahwa persepsi petani terhadap pupuk organik adalah ramah lingkungan, tidak ada kandungan zat kimianya, harganya lebih murah,  mudah di dapat, mudah di buat, produk yang dihasilkan lebih banyak di cari orang, simbol dari gaya hidup yang sehat, harga dari produk yang dihasilkan lebih mahal, hasil yang banyak dalam jangka panjang, pupuk yang dianjurkan oleh pemerintah, harga dari produk yang dihasilkan mahal, produk yang dihasilkan lebih bergengsi, pupuk yang terbuat dari kotoran hewan dan bahan alami lainnya serta tidak mengandung bahan kimia, pupuk organik terbatas produksinya dan susah didapatkan apabila dibutuhkan dalam jumlah yang banyak sekaligus.  Dan tingkat persepsi petani terhadap pupuk organik adalah negatif (35,3).

Abstract

The mangrove ecosystem is one of the many ecosystems found along tropical beaches that have a function as a buffer area between land and sea and produce organic matter. There are several factors that influence the spread of mangrove plants, namely the physical factor of the soil. This study aimed to determine the soil carbon content in the mangrove ecosystem in the village of Temmalebba, South Sulawesi. The data collected in the form of bulk density (BD), organic matter (BO) and percent C for analysis of carbon content was obtained from the analysis of soil samples taken from 10 points with 3 replications for composite samples. The sampling point was determined based on the growth and density of mangroves. Furthermore, the data was analyzed using the organic C equation and carbon content. The results showed that the highest bulk density was found at a depth of 60–100 cm with a value of 1.28 g/cm3. The highest percent of organic matter content found at a depth of 0-30 cm with a value of 9.18%. The highest soil carbon content found at a depth of 60–100 cm with a value of 225.38 (MgC ha-1). Soil carbon content in the mangrove ecosystem of Bone Bay, Temmalebba village is strongly influenced by several factors, including soil depth, bulk density, organic matter, and soil texture.

Abstract

This study aims to determine the comparison of the growth of porang plants managed by agroforestry and monoculture. This research took place from April to May 2021. The data was collected in the form of primary data and secondary data. This study was a completely randomized design consisting of 2 treatments and eight replications on agroforestry and monoculture land so that there were 32 experimental units. Treatment using media M1=Soil (100%) and M2=Soil + husk charcoal. Furthermore, analysis of variance (Manova) was carried out; the analysis of variance showed that on agroforestry land, the treatment had a very significant effect on stem height and substantially impacted the number of leaves. In contrast, in monoculture, the treatment significantly impacted stem height and had no significant effect on the number of leaves. Based on the results of the research, the best porang plant growth was found on agroforestry land that used soil + husk charcoal in terms of plant height parameters and a number of leaves with an average plant height value of 27.2 cm and gave the best results on the number of leaves with an average value of 3 strands. At the same time, the lowest porang plant growth was on monoculture land with an average plant height value of 19 cm and the number of leaves with an average value of 1 strand.

Abstract

The low infiltration rate causes most of the rainwater that falls to the ground to become surface runoff, and only a small portion of the water can enter the ground as groundwater storage. The infiltration in the Tandung Billa IUPHKm location includes the use of forest land, shrubs, and mixed gardens, and the management carried out by the community at the Tandung Billa IUPHkm location is the cultivation of agricultural/plantation crops under tree stands in hilly or slightly sloping areas. Land use in the Tandung Billa Community Forest Utilization Business Permit (IUPHKm) consists of forest land, shrubs, and mixed gardens; each land use affects soil and land conditions, which in turn will affect the infiltration rate of the land. Therefore it is necessary to know how the infiltration rate in forest land use, mixed garden shrubs. Measurement of the infiltration rate was carried out by taking soil samples for physical properties, and soil moisture content in three different land uses, namely forest, shrub, and mixed garden land use; the measurement was carried out using a double-ring infiltrometer. The results showed that the infiltration rate on forest land was classified as medium-fast, namely = 83 mm / hour, with clay texture, then the infiltration rate in shrubland was classified as moderate, namely = .62 mm / hour, with clay soil texture and clay. The infiltration rate in mixed garden land/agroforestry is classified as moderate, namely = 53 mm / hour with a dusty clay texture.

Abstract

This study aims to measure the throughfall of Anthocepalus macrophyllu. The research was conducted in the experimental garden of SMK Neg 4 Luwu, Baramamase Village, Walenrang District, Luwu Regency. The materials used were 6 samples of Anthocephalus macrophyllus trees with a device consisting of a manual rainfall gauge, a hose, a collection bucket, a measuring cup, nails, machetes and a stopwatch. The data collected were rainfall and rainfall at 30 rain events. Of the 30 rainfall events, the throughfall data were selected for rainfall of 100, 150, 300, 400 and 500 cm3, each with 3 replications. Rainfall data is obtained by placing a manual rain gauge at the research location to measure every time it rains. Throughfall measurement is done by placing the collection bucket on the inside under the canopy. The highest average throughfall of 42.67 cm3 is found in the 500 cm3 rainfall with the regression equation y = 0.086x + 1.202 and determination (R2) = 0.8099. While the largest proportion of throughfall with a value of 13.05% occurs in 300 cm3 of rainfall, the regression equation y = 0.0022x + 8.186 and determination (R²) = 0.0247

Abstract

Land use affects changes in peak discharge so that it has the potential to cause or prevent flooding. Sago has morphological characteristics that have the potential to absorb more water. This study aimed to determine the magnitude of the change in peak discharge in the upstream watershed after sago planting. Observations were made on the three growth phases of sago palms (initial, middle, and mature phases). The research stages included calculating the runoff coefficient value under sago stands at three growth phases. Peak discharge of the existing conditions (settlements, rice fields, mixed gardens, shrubs, sand dunes, forests, and water bodies) was estimated after three scenarios of sago land use. The scenarios consisted of 25% of the land area planted with sago (scenario 1), 50% for scenario 2, and 100% for scenario 3. The data were analyzed quantitatively by comparing peak discharge in the existing conditions with scenario results. The results showed that the peak discharge in the existing conditions was 52.36 m3 hour-1. Peak discharge in the initial phase of scenario 1 was 18.94 m3 hour-1, scenario 2 was 37.88 m3 hour-1, and scenario 3 was 75.77 m3 hour-1. Peak discharge in the middle phase of scenario 1 was 19.01 m3 hour-1, scenario 2 was 38.02 m3 hour-1, and scenario 3 was 76.04 m3 hour-1. Peak discharge in the mature phase of scenario 1 was 6.38 m3 hour, scenario 2 was 12.76 m3 hour-1, and scenario 3 was 26.55 m3 hour-1. The peak discharge in the upstream watershed decreased after the scenarios with the use of sago land for all growth phases, except for scenario 3 of the initial and middle phases.

Abstract

The composition and structure of vegetation is one of the parameters that must be considered in forest planning activities. It can also be defined that the structure of vegetation as a result of spatial planning by the components of the stand and the life form of the vegetation which is described through the conditions of diameter, height, distribution in space, canopy diversity, and species continuity. In order to be able to withstand the occurrence of landslides, especially those in sloping areas, it is very important to analyze the vegetation to determine the composition and structure of vegetation types so that the forest is maintained (Fahrul, 2007). The purpose of this study was to determine vegetation in the existing area around the landslides in Palopo city. Research methods. The method of determining plots is purposive sampling, to find out vegetation and tree classification based on the growth rate of the method, namely by making observation plots and placing them by census at the top of 12 landslide points with a size of 20 m x 20 m for trees, 10 m x 10 m for poles, 5 m x 5 m for saplings and 2 m x 2 m for seedlings. The results obtained for the growth rate of trees found 35 species with the highest IVI Litsea sp 95.94%, the growth rate of poles found 28 species with the highest IVI Litsea sp 71.15%, the growth rate of saplings found 62 species with the highest IVI Cinnamomum camphora 45.62 %, and the level of seedlings found 51 species with the highest IVI Nephrolepis cordifolia 40.78%.

Abstract

The distribution of mangrove plants is influenced by various factors, including the physical characteristics of the soil. The study was conducted to determine the physical characteristics of the soil in the mangrove ecosystem in Bone Bay, Palopo City. Soil sampling was performed using the purposive sampling method in five points with three replications based on the equations of growth and density of mangrove vegetation. Physical characteristics of the soil sample, including texture, color, permeability, bulk density, and soil porosity, were analyzed in the laboratory. The results showed that the dominant soil textures were squirming and sandy loam. The dominant soil color was very dark gray. Soil permeability is high and belongs to the fast criteria, with the highest value of 20.0 cm/hour at the fourth depth point of 0-30. The highest bulk density at the fourth depth point is 31-60 cm, with a value of 0.81 gr/cm3. At the same time, the porosity of the soil is classified as a high or good criterion, with the highest value found at the third depth point of 0-30 cm with a value of 77%. In the future, soil physical characteristics data can be used as preliminary information or databases for the government to organize and preserve mangrove forests.
