Limbah kulit mete dapat manfaatkan sebagai bahan baku salah satu industri cat genteng dan minyak rem. Proses ekstraksi konvensional sebagian besar kurang memberikan perpindahan massa sehingga proses ekstraksi lambat dan tidak maksimal untuk mendapatkan minyak kulit mete. Pelarut dalam jumlah yang berlebihan sering digunakan namun membuat proses menjadi mahal dan mencemari lingkungan. Solusi yang tepat dalam mengekstraksi yaitu dengan bantuan ultrasonik. Penelitian ini bertujuan untuk mendapatkan optimasi proses ekstraksi minyak kulit mete dengan mengunakan gelombang ultrasonik dengan fekuensi 42 kHz. Pengaruh yang dipelajari adalah rasio serbuk kulit mete terhadap pelarut n-heksana, dan waktu ekstraksi. Metode permukaan respon dengan rancangan Central Composite Design digunakan untuk memperoleh model matematis yang menggambarkan hubungan antara rendemen minyak kulit mete terhadap rasio dan waktu ekstraksi. Hasil penelitian menunjukkan bahwa kondisi optimum ekstraksi minyak kulit mete pada komposisi perbandingan serbuk kulit mete terhadap pelarut n-heksana sebesar 1:3,25 (g/g) selama 90 menit dengan rendemen sebesar 36,15%. Minyak kulit mete mengandung asam anakardat, kardanol, dan senyawa fenol lainnya. Kata Kunci: kulit mete; ekstraksi; n-heksana; gelombang ultrasonik; asam anakardat ABSTRACT: Cashew shell waste can be utilized as a raw material for one of the tile paint and brake oil industries. The conventional extraction process mostly provides less mass transfer, so the extraction process is slow and not maximal. Excessive amounts of solvents are often used but make the process expensive and pollute the environment. The right solution in extracting is with the help of ultrasonic. This study aims to obtain an optimization of cashew oil extraction process using ultrasonic waves with a frequency of 42 kHz. The effect studied was the ratio of cashew powder to n-hexane solvents and extraction time. The surface response method with the design of Central Composite Design was used to obtain a mathematical model that illustrates the relationship between the yield of cashew shell oil to the ratio and time of extraction. The results showed that the optimum condition of cashew nut oil extraction in the comparison composition of cashew skin powder against n-hexane solvent was 1: 3.25 (g / g) for 90 minutes with a yield of 36.15%. Cashew skin oil contains anacardic acid, cardanol, and other phenol compounds.

Publikasi merupakan tahap akhir yang penting dilakukan dalam penulisan karya ilmiah. Publikasi adalah cara yang dilakukan agar karya atau hasil temuan dapat dikenal secara luas, sehingga dapat menambah dan mengembangkan ilmu pengetahuan. Guru dituntut tidak hanya mengajar tetapi juga menghasilkan karya atau temuan. Salah satu bentuk pengembangan profesi guru adalah pengembangan kemampuan guru dalam membuat karya tulis ilmiah. Kemampuan ini dapat dilihat dari publikasi para guru yang dimuat dalamberbagai media, khususnya jurnal ilmiah. Namun sebagian besar guru tidak mau menyusun dan melakukan publikasi karena membutuhkan waktu dan tenaga, sehingga guru hanya menyusun karya ilmiah tanpa melakukan publikasi. Program ini berupa sosialisasi mengenai publikasi karya ilmiah dimaksudkan untuk memberi pengetahuan dan memotivasi guru agar melakukan publikasi karya ilmiah ke dalam jurnal. Selain itu, dilakukan juga pelatihan publikasi karya ilmiah ke dalam jurnal sehingga dapat dilakukan sendiri oleh guru-guru khususnya guru SMK Al-Inabah. Hasil kegiatan ini yaitu pengetahuan guru tentang publikasi artikel makin meningkat.

AbstrakPerkembangan penyakit pada manusia saat ini semakin beragam dan berjalan relatif cepat. Salah satu penyebab timbulnya berbagai penyakit tersebut yaitu mikroorganisme seperti bakteri Escherichia coli. Pengobatan yang biasa dilakukan masyarakat yaitu menggunakan obat-obatan kimia, yang dapat menimbulkan efek resisten pada bakteri bahkan efek samping bagi pasien, sehingga penting untuk dilakukan usaha pemanfaatan tanaman sebagai bahan obat herbal dengan memanfaatkan limbah biji buah jeruk manis sebagai antibakteri. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri biji jeruk (Citrus sinensis) terhadap bakteri Escherichia coli. Jenis penelitian ini adalah eksperimental laboratorium dengan menggunakan metode difusi untuk uji aktivitas antibakterinya. Penelitian dilakukan dengan tahapan sebagai berikut: (1) preparasi sampel berupa serbuk biji jeruk, (2) maserasi serbuk biji jeruk dengan pelarut n-heksana dan etanol, (3) uji antibakteri. Hasil penelitian menunjukkan bahwa biji jeruk menghambat pertumbuhan bakteri E.coli dengan zona hambat ekstrak n-heksan dan etanol sebesar 7,93±1,90 mm dan 18,27±2,40 mm. Biji jeruk manis (Citrus sinensis) memiliki potensi sebagai antibakteri. AbstractDevelopment of disease in humans is increasingly diverse and runs quickly. One cause of the incidence of various diseases are microorganisms such as Escherichia coli. The usual treatment is the use of chemical drugs, which can cause the effects of resistance to bacteria and even side effects for patients, so it is important to do business utilization of plants as herbal medicinal materials by utilizing the waste of sweet orange seeds as an antibacterial.

Buluharjo Village, Magetan Regency is a rural area, the majority of which are horticultural crops. Shallots are one of the commodities in the region. The productivity of shallots for the last three years has decreased due to the reduction in agricultural land caused by the construction of housing projects. The decline in shallot production is caused by the lack of land and the presence of plant pests such as worms, caterpillars, fungi and bacteria. The use of high chemical fertilizers, improper selection of seeds makes the quantity and quality of shallot production not optimal. The purpose of the activity is to provide training on red onion cultivation with verticulture techniques as a solution for using narrow land. The method used is pre survey, survey, socialization and training. The activity was carried out for 6 months. The result of the activity is an increase in understanding of modern agricultural techniques, namely verticulture in the field of red onion farming. Public understanding of modern agricultural systems, and increasing the productivity of shallots. The community is very enthusiastic and actively involved in applying vertical culture techniques. The community can apply the shallot verticulture technique on narrow land.

Genitri (Elaeocarpus sphaericus Schum.) is an endemic plant of Indonesia that has not been widely cultivated and utilized. The use of genitri is usually as road shade, firewood, seeds for jewelry. The results showed that the diversity of chemical compounds genitri had potential for health. The aim of the study was to analyze the potential of genitri to leukocytes and lung tissue structure of wistar rats induced by influenza virus. The study used an experimental approach, with experimental animals in the form of 24 male wistar rats in 4 treatment groups, P0 negative control, P1 influenza virus induction (positive control), P2 influenza virus induction and given genitri leaf, and P3 influenza virus induction and given genitry seeds. Virus induction on day 0 and day 14. Leaves and seeds were given on the 3rd day. Surgery was performed on day 5 and day 33. The number of leukocytes were calculated using microhematocrit, and identified leukocytes and lung tissue structure staining with HE staining. The results showed that genitry seeds could increase the number of leukocytes up to 13,000 cells/µL, the size of the alveoli diameter was 31.48 m, the size of the alveolar septum was 12.02 m.  Keywords: Antiviral, Elaeocarpus Sphaericus Schum, Genitri, Leukocytes, Pulmo
