Abstract

At this time, the leaf authentication method is widely used in the classification process of herbal plants. Basically, the leaf authentication method compares the image to be identified and the reference image created in the dataset. This paper aims to identify the leaves of herbal plants using an artificial intelligence method, namely Convolutional Neural Network (CNN) that is embedded on Raspberry Pi. CNN has an advantage that it does not require feature extraction, because in CNN, automatic feature extraction already exists. This paper uses seven types of leaves from different herbal plants. Leaf images are taken using a camera and processed by Raspberry Pi, which is integrated with CNN. Identification was carried out on seven types of herbal plants divided into two-thirds of training data and one-third of testing data. The identification process results will be validated with other data not included in the training data and testing data, as well as leaf data other than the seven types of leaves identified. The CNN method shows good results in the authentication process, with an accuracy rate of 93.62% for testing data offline and 91.04% for testing data online.

Abstract

Pada proses penggilingan padi menjadi beras dihasilkan 8-10% dedak padi. Pemanfaatan dedak padi umumnya baru sebatas sebagai pakan ternak. Padahal pada dedak padi terdapat minyak sekitar 10-26% dari berat dedak padi. Minyak dedak padi dilaporkan sebagai minyak nabati unggul karena minyak tersebut didoninasi oleh asam lemak tak jenuh. Minyak dedak padi mengandung sekitar 32-35% asam linoleat. Asam linoleat dilaporkan mampu menurunkan kolesterol darah dan mencegah aterosklerosis. Berbagai metode ekstraksi telah diterapkan untuk mengekstraksi minyak dedak padi. Metode ekstraksi soxhlet merupakan metode yang dianggap paling cocok untuk mengektraksi minyak dedak padi. Namun metode tersebut umumnya hanya diterapkan pada ekstraksi skala kecil. Tujuan penelitian ini adalah memodifikasi metode ekstraksi soxhlet menjadi metode ekstraksi kolom unggun tetap, dan mempelajari pengaruh jenis pelarut dan ketinggian unggun (dedak padi) terhadap rendemen dan sifat fisiko-kimia dari minyak dedak padi yang dihasilkan. Hasil penelitian menunjukkan bahwa penggunaan pelarut etil asetat menghasilkan rendemen minyak dedak padi lebih banyak dibandingkan dengan pelarut etanol untuk semua variasi ketinggian unggun dedak padi. rendemen maksimum minyak dedak padi sebanyak 18,2% diperoleh pada ekstraksi dengan pelarut etil asetat dan pada ketinggian unggun dedak 5 cm. Pada kondisi ekstraksi tersebut dihasilkan minyak dedak padi dengan sifat fisiko-kimia paling optimal, yaitu dengan bilangan asam, bilangan penyabunan, bilangan iod, densitas, indeks bias, dan viskositas berturur-turut sebesar 48,3 mg KOH/g, 252,1 mg KOH/g, 105,4 g I2/100 g, 0,910 g/mL, 1,463, dan 6,3 mPa s.

Abstract

Biodiesel, which is a methyl ester of fatty acids, has been considered as a renewable fuel that is environmentally friendly because it is able to support the sustainability of the carbon dioxide cycle. Biodiesel is conventionally synthesized from oil or fat with a homogeneous base catalyst, such as potassium hydroxide or sodium hydroxide. However, the use of homogeneous catalysts has several drawbacks, such as: it requires a tight free fatty acid content, is prone to oil saponification reactions, is relatively difficult to separate, and cannot be regenerated. Therefore, heterogeneous catalysts in biodiesel synthesis are considered as a substitute for homogeneous catalysts. Calcium oxide is a solid heterogeneous catalyst that has been proven effective in assisting the transesterification reaction of oil into biodiesel. Calcium oxide can be synthesized from calcium carbonate, which is widely found in waste, such as blood clam and egg shells. This study aims to synthesize and characterize calcium oxide from egg and crab shells as a catalyst in the synthesis of biodiesel from used cooking oil. Calcium oxide was obtained by calcination to blood clam and egg shells at 800 oC for 8 hours. The calcination results were further characterized by the method of x-ray diffraction and BET (Brunauer-Emmet-Teller) isotherm adsorption-desorption to determine the type of oxide phase formed and the surface characterization. The synthesis of biodiesel was carried out at a reaction time of 2 hours, a temperature of 60 oC, a molar ratio of oil to methanol 1:12, and a catalyst content of 10%. The results showed that calcium oxide was successfully synthesized from blood clam and egg shells waste with different characteristics. Calcium oxide from the two wastes is able to catalyze the transesterification reaction of used cooking oil into biodiesel, and biodiesel is produced according to SNI 7182-2015 concerning biodiesel quality standards.

Abstract

Copper ion as one of the pollutants in industrial wastewater can be treated by the adsorption method. One type of adsorbent can be prepared from rice husk. Rice husk as agricultural waste contains carbon and silica which can act as metal adsorbents. The purpose of this study was to synthesize and characterize silica/carbon composites, as well as test their adsorption as adsorbent on copper (II) ion adsorption by determining the optimum composition of silica/carbon, adsorption capacity, and model of isotherm adsorption. The research method consisted of gasification of rice husks, extraction of silica from rice husk charcoal with potassium carbonate as solvent, manufacture of silica/carbon composites, and adsorption tests. The results showed that the mass ratio of silica to carbon of 2:1 was the optimum composition in the synthesis of silica/carbon composites as adsorbent for the adsorption of copper (II) ion. The silica/carbon composite adsorbent in this composition had the highest adsorption capacity for copper (II) ion and surface area is 75.88 mg/g and 233.45 m2/g, respectively. The optimum adsorption time was obtained for 40 minutes and the model of adsorption isotherm in the form of Freundlich adsorption with R2 = 0.9582.   Abstrak Ion tembaga sebagai salah satu polutan dalam air limbah industri dapat ditangani dengan metode adsorpsi.

Abstract

As an elementary school teacher, we sometimes encounter problems in learning science. Through reflection activities, the teacher realized that in class IV SDN 3, Karangrandu's mastery of Energy and Heat Transfer material was still low. In the 2022/2023 academic year, out of 30 students, only ten students, or around 33% of students, achieved the minimum standard of completeness. To increase learning outcomes, a class action research step is needed through the inquiry method. The subjects of this classroom action research were students in class IV of SDN 3 Karangrandu, Pecangaan District, Jepara Regency, with 30 students recorded, with details of 20 female students and ten male students. This improvement in science learning will be carried out in the 2022/2023 academic year semester I for class IV. Research on pre-cycle found that 33% of students completed it. Then, in the first cycle of learning improvement, there was another increase, which was proven by the evaluation results of students who reached 77% and the KKM. Finally, cycle II improved the skills and understanding of Energy and Heat Transfer, and students can mention examples of conduction, convection, and radiation. Twenty-eight students obtained a score range of 70-80, meaning their completeness level reached 94%.

Abstract

Changes in land use and cover of an area significantly affect the quality of the area, especially from a socio-economic perspective. If city and regional governments are unable to anticipate these changes, it can greatly impact the security of the area, such as a lack of availability of public facilities, increased crime, and other social aspects. Research on changes in land use and cover has mostly focused on agriculture and rarely addresses regional security. Therefore, this study focuses on changes in land use, particularly in the type of urban residential land use in Bekasi city. The data used are Landsat satellite images from two different years for the Bekasi city area, utilizing trend change analysis with the Idrisi Selva application. Initially, a land cover classification process was carried out using the Iterative Self-Organizing Clustering (ISOCLUST) method, followed by reclassification with the same application into five classes: agriculture, vacant land, buildings, vegetation, and water bodies. The results show the direction of land change development where residential areas increase in the direction according to the degree of trend change, namely to the lower middle for the third degree and to the northwest and lower middle for the fifth degree. The research results can be used by regional planners in creating Spatial and Regional Plans (RTRW) as well as Detailed Spatial Plans (RDTR).
