Abstract

Production of paddy in a different place is caused by several factors such as soil type, soilnutrient content, pests and diseases, climate change and cultivation techniques. Because ofthese differences, to find out the productivity of land in a large area needs technology so thatthe results are more appropriate. For this reason, this study was conducted with the aim ofestimating land productivity using technology that reflects plant reflectance in several croppingpatterns. , taking a portrait of land appearance and measuring grain productivity to be used asvalidation data. The data is processed by linking reflectance (vegetation index), color, plantdensity and productivity of paddy rice in the same area. The results show that there is arelationship between plant density with the productivity of paddy fields (tons/ha) with acoefficient of determination (R2) that is 0.7. Rice plants in Legowo 2-1 cropping pattern havemore influence on the index increase compared to the Tegel planting pattern. The relationshipbetween the vegetation index and rice productivity (tons/ha) is weak in SR, NDVI, SAVI, MSAVI,and IPVI and is strong in RDVI

Abstract

Pemotongan padi saat panen secara manual dengan sabit menyebab tingkat kehilangan mendekati 5%. Sekitar 1000 ha persawahan yang ada di kecamatan Tompobulu berada pada ketinggian 500 meter dari permukaan laut (mdpl) dengan petakan-petakan kecil (<0,15 ha) dan berpola sawah terassering. Masalah utama yang dihadapi petani di kecamatan Tompobulu kabupaten Bantaeng dalam penanganan panen padi adalah tingginya susut (losses) baik secara kuantitatif maupun kualitatif. Permasalahan tersebut berakibat adanya kecenderungan tidak memberikan insentif kepada petani untuk memperbaiki tingkat pendapatannya. Padi atau gabah yang kadar airnya tinggi mempunyai sifat mudah rusak dan akan mengalami susut pada saat penanganan panen. Menurut BPS (2021) angka produksi gabah sebesar 75 juta ton GKG (Gabah Kering Giling) sesungguhnya dapat lebih tinggi lagi apabila dilakukan penanganan yang baik pada saat panen (2). Hasil survei Badan Pusat Statistik (BPS, 2021) menunjukkan bahwa susut hasil panen padi di Indonesia saat ini masih cukup tinggi, yaitu 9,5% yang terjadi pada saat panen dan 4,8% saat perontokan (2). Penanganan panen yang baik dan tepat dapat menekan susut dan menghasilkan kualitas gabah/beras yang tinggi sehingga dapat meningkatkan harga jual gabah/beras petani. Teknologi penekanan kehilangan hasil yang dipilih untuk diterapkan harus teknologi yang sesuai dengan spesifik lokasi. Secara umum metode atau teknologi untuk menekan kehilangan hasil panen dapat ditempuh dengan sistem panen beregu, yang dilengkapi dengan unit alat pemotong dan perontok dengan penerapan proses yang baik. Pada daerah dengan pemilikan lahan sempit, penerapan teknologi yang dapat dilakukan yaitu dengan cara pengembangan sistem panen yang dilengkapi dengan mesin pemotong padi (power rice cutter) dan perontok padi atau Power Thresher.

Abstract

One of the basic needs, especially for the people of Indonesia, is rice. This causes the demand for rice to increase day by day in accordance with population growth. Therefore, rice production in Indonesia is expected to meet the basic needs of the Indonesian population. Estimating the level of rice production is important to determine the level of food availability in an area. Image data obtained from drones and sentinel images can be analyzed to obtain vegetation indices and used to predict rice production. The purpose of this research is to see the relationship between the RGB vegetation index of drone imagery and the NIR-based index of sentinel imagery with rice production. in this study, a regression analysis was conducted between the vegetation index values ​​obtained from drone imagery and sentinel-2 imagery with rice paddy production then the equation obtained from the regression analysis was used to estimate rice paddy production on the rice fields used as test samples. Correlation analysis was also conducted where this analysis was used to see how strong the relationship is between the vegetation index used and rice production. As for the results obtained, there are three levels of relationship obtained from the results of correlation analysis between several vegetation indices used, namely strong, medium and very strong levels. The TGI vegetation index shows a moderate level of relationship, while the strong level consists of the VARI, ExG, RGBVI and GLI vegetation indices. And at a very strong level shown by the NGRI, NDVI and NDRE vegetation indices. Estimation of rice production can be predicted with the NDRE vegetation index which has the highest determinant value, which is 84.06%. Validation of the NDRE vegetation index shows a result of 55.97%, where more data is under estimate which means the estimation results are smaller than the results obtained in the field.

Abstract

Land cover changes occurring in a watershed will affect the ecosystem in that area. The Soil and Water Assessment Tool (SWAT) model is a tool that can be used to predict the impacts of land use on water, sedimentation, and chemical levels in a watershed. The Mamasa watershed is one of the sub-watersheds of the Saddang watershed, covering approximately 105,253 ha. This study aims to determine the land cover changes in the Mamasa watershed and their impacts on water discharge using the SWAT model. Several steps were undertaken, including image interpretation to obtain an overview of land cover in the years 2011, 2016, and 2020, which were then used to form Hydrology Response Units (HRU). Next, the SWAT model was run, involving delineating the watershed boundaries, defining HRU, integrating climate and HRU data, running SWAT simulations, and performing validation. The results of land cover classification from 2011 to 2016 showed an increase in secondary forest land by 4,896.68 ha (4.65%) and a decrease in shrubland by 9,500.60 ha (9.03%). The land cover classification from 2016 to 2020 indicated a decrease in secondary dry forest land by 6,349.43 ha (6.03%), with an increase in paddy field area by 3,141.92 ha (3%). These land cover changes led to a decreasing trend in water availability, as evidenced by increased discharge fluctuations from 16.50 to 21.65, in accordance with the SWAT simulation results, which increased from 6.73 in 2011 to 9.93 in 2020. The validation results of the SWAT model for the year 2011 showed a Nash-Sutcliffe Efficiency (NSE) value of 0.58 and and R2 value of 0.61. The validation for the year 2016 resulted in an NSE of 0.6 and an R2 of 0.68, while the validation for the year 2020 produced an NSE of 0.6 and an R2 of 0.65. All three validations fall under the satisfactory category, indicating that the SWAT model can be used to simulate the discharge of the Mamasa watershed.

Abstract

Spectrometer is one of the tools that can produce a spectrum of light with certain wavelengths. A wavelength produced by measurements using a spectrometer will produce absorbance, reflectance and transmittance values. The result of light absorbed by the object is called absorbance, the light reflected by the object is called reflectance, while that which is not absorbed and not reflected by the object is called transmittance.Objective. The purpose of this study are the wavelength, absorbance value, reflectance and its relationship to color in the post-harvest process so that it is expected to be a reference and can provide information about wavelength, absorbance value, reflectance and its relationship to color in the post-harvest process.Methods. Measuring wavelenght, absorbance and reflectanceduring the postharvest process, both before treatment and after treatment. Results. The results obtained are the absorbance value of fresh green coffee of 0.98%, fresh yellow coffee of 0.18% and red coffee of 0.27%. However, after going through the post-harvest process there is a change in the absorbance value where green coffee that has been dried using the yellow honey method has decreased by 0.92% and the black honey method is 0.38% while yellow and red coffee beans have increased at wavelengths ranging from 300-400 nm and 400-500 nm, as well as roasted coffee. While the reflectance value can be seen that fresh green coffee has a reflectance value of 92%, yellow coffee is 89% and red is 69%. However, after going through the post-harvest process where green and yellow coffee that has been dried using the black honey and yellow honey methods has decreased and red coffee beans have increased at wavelengths around 900-1000 nm, as well as roasted coffee, therefore, can be concluded that the post-harvest process causes the absorbance and reflectance values to change at the same wavelength.These findings are expected could provide the information regarding the change of wavelength, absorbance and reflectance during coffee processing.

Abstract

Kuliah Kerja Nyata (KKN) adalah respons terhadap tuntutan zaman yang menekankan bahwa perguruan tinggi harus berperan lebih dari sekadar pusat pendidikan, tetapi juga sebagai agen perubahan dalam masyarakat. KKN menyediakan kesempatan bagi mahasiswa untuk mengaplikasikan ilmu dan keterampilan yang telah dipelajari selama di kampus ke dalam situasi nyata di masyarakat salah satunya di Desa Kaluku, Kecamatan Batang, Kabupaten Jeneponto, di mana sebagian besar penduduk bekerja sebagai petani karena desa tersebut memiliki lahan yang luas. Tanaman yang banyak dibudidayakan di daerah ini meliputi padi, jagung, kacang tanah, pisang, dan kacang hijau. Namun, para petani masih menggunakan teknik tradisional, khususnya dalam proses pemupukan, yang dilakukan secara manual menggunakan tangan. Metode ini memakan banyak waktu, tenaga, dan sumber daya manusia. Untuk menjawab tantangan tersebut, hadir inovasi lokal berupa alat penabur pupuk. Alat ini dirancang untuk mempermudah proses pemupukan dengan tingkat akurasi yang tinggi, sehingga nutrisi dapat tersebar merata ke seluruh tanaman. Selain menghemat waktu dan tenaga, alat ini juga mengurangi pemborosan pupuk dan berpotensi meningkatkan produktivitas hasil panen. Penggunaan teknologi ini memberikan solusi praktis bagi petani untuk menghadapi tantangan dalam sektor pertanian.
