ABSTRACT In Desa Timuhun, eventhough papaya is not primary fruit product, but usually papaya is planted among the other plants and easily to grow. Papaya has good potency to be processed to become food product. Matured papaya fruit is usually fresh served for desk fruit. On the other hand, for papaya which is not mature yet, usually used for vegetable. Papaya has high water content, so it makes papaya fruit easy to experience damage. With papaya processing, papaya which is originally assumed improper to be sold or to be consumed (mechanical damage, diseased, acid, physical damage) and will only to be thrown, finally can be used. The making of papaya dry candy is one of effort to preserve and to vary form of papaya serving. It also improves the economic value of papaya. The making of papaya can be conducted in big or small scale. The activity objectives are to introduce and give additional knowledge to society about papaya processing technology, to increase economic added value of papaya and the using of papaya which is improper to be sold or to be consumed becoming valuable food product .Realization of the objectives above are by performing an information sharing and discussion with the society about process of the making dry candy from papaya, training of papaya dry candy making, introduce simple technology of dry candy papaya making. This activity was performed at the head of Desa Timuhun office, on Friday, September 14, 2007 and was attended by 26 persons, including association of woman farmer and the staff in that office. The result of this activity shows that there was positive response of people who attend this activity, because by processing papaya fruit into dry candy, have a lot of advantage compare to sale it freshly. Beside that, this dry candy is healthy snack, without synthetic preservation, enriched with vitamins which is useful for health, also this dry candy is still good up to 1 month and of course it could to improve economic value compared to be sold freshly

ABSTRAK Ketidakseimbangan unsur hara dan kualitas tanah yang kurang optimal merupakan permasalahan umum di lahan pertanian, namun pemantauan unsur hara memerlukan analisis laboratorium. Tujuan penelitian adalah memperoleh hubungan untuk mengestimasi pH tanah, kandungan nitrogen total, karbon total dan bahan organik tanah berdasarkan konduktivitas listrik tanah, serta mengevaluasi potensi penggunaan konduktivitas listrik tanah sebagai indikator estimasi parameter-parameter tersebut. Penelitian menggunakan machine learning berbasis Python dengan algoritma regresi linear, di mana 70% data digunakan untuk membuat persamaan pendugaan dan 30% untuk validasi kinerja model. Hasil penelitian menunjukkan bahwa konduktivitas Listrik (EC) dapat digunakan untuk memprediksi nilai pH dengan persamaan pH = 0,3107 EC - 1,2 (nilai R² = 0,9707), untuk memprediksi nilai karbon total dengan persamaan TC = 0,3525 EC - 0,1 dan untuk memprediksi nilai bahan organik, dengan persamaan BOT = 0,2045 EC - 0,1 dengan nilai R² = 0,9126. Namun, nilai EC dinyatakan lemah untuk memprediksi nitrogen total dengan nilai R² = -0,0030. Validasi kinerja model menunjukkan nilai kesalahan yang sangat kecil pada persamaan untuk memprediksi pH berdasarkan nilai EC yaitu MSE = 0,0006; MAE = 0,0164), serta pada persamaan untuk memprediksi karbon total dan bahan organik tanah berdasarkan nilai EC diperoleh masing-masing nilai MSE = 0,0017 dan MAE = 0,0357). Namun nilai EC kurang efektif untuk memprediksi nilai nitrogen total karena hasil validasi kinerja model menunjukkan nilai MSE = 0,0195 dan MAE = 0,1190. Hasil ini menunjukkan bahwa konduktivitas listrik tanah dapat digunakan sebagai indikator yang baik untuk mengestimasi pH tanah, karbon total, dan bahan organik tanah. ABSTRACT The imbalance of soil nutrients and suboptimal soil quality are common issues in agricultural land; however, monitoring soil nutrients typically requires laboratory analysis. This study aims to establish relationships for estimating soil pH, total nitrogen content, total carbon, and soil organic matter based on soil electrical conductivity (EC), as well as to evaluate the potential use of EC as an indicator for estimating these parameters. The research employed a machine learning approach using Python with a linear regression algorithm, where 70% of the data was used to develop estimation equations and the remaining 30% for model performance validation. The results indicate that EC can be used to predict pH with the equation pH = 0.3107 EC - 1.2 (R² = 0.9707), total carbon with the equation TC = 0.3525 EC - 0.1, and soil organic matter with the equation BOT = 0.2045 EC - 0.1 (R² = 0.9126). However, EC was found to be a weak predictor for total nitrogen, as indicated by an R² value of -0.0030. Model validation results showed very low error values for the pH prediction equation (MSE = 0.0006; MAE = 0.0164), as well as for the equations predicting total carbon and organic matter (MSE = 0.0017 and MAE = 0.0357, respectively). In contrast, EC was less effective in predicting total nitrogen, as reflected in higher error values (MSE = 0.0195; MAE = 0.1190). These findings suggest that soil electrical conductivity can serve as a reliable indicator for estimating soil pH, total carbon, and organic matter content.

Land processing activities in Subak can reduce the develo pment of weeds, loosen the soil, and condition the biophysical properties of the soil. Subak in Bali is generally processed using hand tractors (either equipped with singkal plows or rotary plows). I f using a singkal plow, the stages of tillage include mak al (turning the soil), nyacahin (reducing the size of the chunks of soil), and then ngasahan (leveling). This research aims to determine the efficiency of land processing in the second stage of land processing in Subak using singkal tractors and rotary tra ctors. This research uses the observation method and measures the real (field) working capacity of the tractor used during land processing. Some of the assumptions used in this research are that the technical condition of the tractors used, the tractor acc essories used, and the operator's skills are assumed to be the same. The results showed that the performance efficiency of the rotary tractor in the nyacahin process (second stage of tillage) in Suba k was 41% and the performance efficiency of the singkal t ractor was 17.8%.

The purpose of this study was to maintain minimum moisture content for switchgrass bales that were inoculated with Pleurotus ostreatus, a white-rot fungus, in order to start the breakdown of lignin for conversion to ethanol. The moisture content was to be maintained above 50%, which would be monitored using load cells to determine the weight. Three bales were used, and thermocouple wires and hose system were placed at four points inside each bale. In addition, the ambient temperature and relative humidity inside the building were monitored. Bales were inoculated with 1%, 2%, and 3% grain spawn by mass. The inoculation was carried out by taking the bale apart in four places and sprinkling or spreading the fungal spawn over the bale. In order to continuously record the voltage readings from the strain gauges, NI USB-6225 data logger and National Instruments’ LabVIEW program was used to record and control the system. The develop automatic weighing and watering system had been able to maintain the bale moisture within the acceptable range and the fungus were observed growing. Some issues related to voltage readings and uniformity of water distribution must be addressed for future work
