Traditionally, ketapang plants are widely used by people to treat diseases of the skin such as scabies, ringworm, and other skin diseases caused by bacteria and fungi. Phytochemical screening on ethanol extract and ketapang leaf extract that grows in Pekanbaru City has never been done. The purpose of this study was to identify active compounds in ethanol extract and extract fraction of ketapang leaves that grew in Pekanbaru City. Based on phytochemical screening results, it is known that ethanol extract of ketapang leaves contains alkaloids and flavonoids, in the hexane fraction contains steroids and ethyl acetate fractions contain flavonoids.

Papaya (Carica papaya L) is a very popular and important fruit in the tropical part where as a nutritious plant that can cure diseases. every part of papaya plants can be utilized start, roots, stems, leaves, fruit and even seeds of fruit. Traditionally papaya seeds can be used as a roundworm drug indigestion, diarrhea, skin diseases, colds, and as a source to get oil with fatty acid content. This research uses extract and steep seeds on papaya fruit with Escherichia coli test bacteria, Salmonella typhi, and Staphlycoccus aureus. From this research we get the result of inhibitory power : Escherichia coli at concentrations of 20%, 40%, 60% 80% and 100% were 8.72 mm; 9.53 mm; 10.61 mm; 10.99 mm; and 12.19 mm. Salmonella thypi at concentrations of 20%, 40%, 60% 80% and 100% were 7.07 mm; 8.63 mm; 9.54 mm; 9.78 mm; and 10.16 mm. Staphylococcus aureus at concentrations of 20%, 40%, 60% 80% and 100% was 6.4 mm; 6.8 mm; 7.8 mm; 7.9 mm; and 10.1 mm.

In this paper we studied the bioactive compounds of Flavonol-D-alanil D-alanin dekarboksipeptidase receptor interactions In silico. First, prepared three dimensional structure of D-alanil D-alanin dekarboksipeptidase as receptor. Preparation of fourth bioactive compounds of flavonol which will be as ligands, klokasilin and D-alanil D-alanin as a comparison. The fourth bioactive compounds of flavonol, klokasilin and D-alanil D-alanin were docked with D-alanil D-alanin dekarboksipeptidase until energy values were obtained. The fourth bioactive compounds of flavonol had lesser binding energy values than D-alanil D-alanin, Quercitrine and rutin also predicted to have greater binding energy and binding affinity than klokasilin (antibiotic) and D-alanil D-alanin (nature ligand).

Sebagai penyambung generasi muda di masa yang akan datang, pendidikan harus diberikan dengan baik pada anak sejak dini. Pendidikan yang baik dapat dimulai dengan meningkatkan kemampuan dan minat baca anak karena membaca adalah jendela dunia. Lemahnya kemampuan dan minat baca anak dapat memengaruhi kualitas anak dalam mengikuti perkembangan ilmu pengetahuan dan informasi selama menempuh pendidikan. Maka dari itu, Program Kemitraan Masyarakat Stimulus (PKMS) ini bertujuan untuk dapat meningkatkan minat baca dan pengetahuan anak-anak di Panti Asuhan Darul Ilmi Pekanbaru. Program PKMS dilakukan dengan tiga kegiatan utama yaitu peningkatan minat baca melalui donasi buku bacaan anak, peningkatkan pengetahuan anak melalui penyuluhan obat dan workshop kartu kuartet anti penyalahgunaan obat, serta evaluasi minat baca dengan metode observasi dan evaluasi tingkat pengetahuan anak-anak panti dengan menggunakan kuesioner. Berdasarkan hasil observasi, donasi buku bacaan anak dapat meningkatkan minat anak untuk membaca karena buku yang diberikan sesuai dengan usia dan kebutuhan anak-anak yang ada di panti asuhan. Penyuluhan dan workshop kartu kuartet juga menunjukkan adanya peningkatan skor rata-rata antara sebelum dan setelah pelaksanaan penyuluhan obat dan workshop kartu kuartet. Hal ini menunjukkan minat baca dan pengetahuan anak-anak panti asuhan mengalami kenaikan setelah penyelenggaraan program PKMS ini.

One of the primary food from Indonesia is sago, and one of the sago producers is the Meranti islands. In addition to processed sago products into foodstuffs, sago products are also sold as sago starch. This study discusses the three factors that influence the market price of sago starch are the number of sago farmers, the area of sago land and annual production. Machine learning approach used is the linear regression. After training data, it can be observed that there are two factors that have a significant influence on the market price of sago starch. The results can be reference material for the industrial and trading offices of Meranti islands in observing the annual sago price so that the farmers and sago entrepreneurs can get the appropriate price of sago starch.
