Abstract

radiation, fast food, limited exercise time, stress due to work cannot be avoided, and also from the results of oxidation processes in the body. The development of degenerative diseases caused by free radicals can be inhibited by antioxidant compounds which are able to ward off free radicals. Therefore, the body needs important substances - antioxidants - that help protect it from attacks by free radicals and radical compounds. At certain concentrations, antioxidants can inhibit or slow down the damage caused by oxidative processes. Brewing time has an important role in determining the taste, aroma and active compound content of tea. The need for clear guidance regarding brewing times is becoming increasingly important, especially with the increasing interest in premium tea drinks and the influence of healthy lifestyles. This research aims to know the relationship between brewing time and tea quality in terms of dissolved antioxidant bioactivity content.  This research activity tested the antioxidant activity of Sapar leaf tea with different brewing times, namely 3, 5, 10, 15, 20 and 30 minutes. Antioxidant activity testing uses the DPPH (1,1-Diphenyl-2-picrylhydrazy,) method. From the test results it was found that Sapar leaf tea (Fordia splendidissima (Miq) Buijsen) with a brewing time of 3 minutes had the highest antioxidant bioactivity with a radical inhibition value of 81.46% and the antioxidant bioactivity decreased as the brewing time for the leaf tea became longer.

Abstract

This research is based on the background that oil palm plantations are a form of community farming that cultivates oil palm plants with production in the form of fresh fruit bunches (FFB) as one of their sources of livelihood, although investment in oil palm plantations requires a relatively long period of time compared to oil palm plantations. with other plantation commodities. The purpose of this study was to determine the oil palm farming business in Saliki Village based on FFB production and palm oil prices. The data collection method used in this study is a qualitative method, which is a research that is used if the research factors cannot be quantified or cannot be calculated so that the variables cannot be expressed with numbers such as perceptions, opinions, assumptions and so on. According to qualitative research theory, in order for the research to be of really high quality, the data collected must be complete, namely primary data and secondary data. From the results of this study, it can be concluded that oil palm farming in Saliki Village based on the production of fresh fruit bunches and the price of palm oil really helps farmers increase their income from farming by selling large quantities of produce and high selling prices. The income they generate from oil palm plantations can meet their daily needs. In addition, the community (oil palm farmers) can buy vehicles, renovate and even build houses from the results of the oil palm plantations. The results of this study are to provide information to the community in Saliki Village in order to be able to improve oil palm farming.

Abstract

Background: Berkuranganya lahan subur, cekaman alam dan biotik terhadap lahan pertanian di Kalimantan Timur menuntut tindakan adaptasi yang bermuara pada peningkatan produktivitas dan keberlanjutan usaha pertanian. Adaptasi dan keberlanjutan menuntut inovasi kreativitas yang didasarkan riset, dengan adanya kegiatan produksi kompos biochar menggunakan mesin pencacah maka kuantitas hasil produksi akan semakin bertambah yang akan berpengaruh pada jumlah dan kualitas hasil pertanian. Tujuan dari kegiatan pengabdian ini adalah untuk memberikan pemahaman kepada masyarakat mengenai upaya peningkatan produksi kompos biochar pembenah tanah melalui rekayasa konstruksi mesin pencacah bahan organik. Mitra pada kegiatan pengabdian ini adalah Lembaga Swadaya Masyarakat (LSM) P4S Puri Leisa. Metode: Untuk mengatasi permasalahan maka diadakan penyuluhan dan pelatihan terhadap 15 – 20 orang petani dan mahasiswa, dengan materi teori dan praktek pembuatan kompos biochar selama 1 hari (4 jam) antara lain Penyiapan Alat Pirolysis, Pemilihan Bahan Biochar, Proses Pembakaran, Pemantauan Suhu dan Pemadaman, Penjemuran, Aktivasi dan Penepungan, Analisis dan Distribusi.  Hasil: Pada tahap awal kegiatan pengabdian, para peserta pelatihan mendapatkan kulsponsi penjelasan prosedur cara membuat kompos biochar dari instruktur. Tahap kedua adalah praktik dengan memasukkan bahan-bahan organik yang berasal dari limbah pertanian dan serasah kehutanan ke mesin pencacah untuk menghasilkan serbuk yang seragam sebelum akhirnya diproses menjadi biochar.  Limbah pertanian serta limbah kehutanan atau limbah alami organik lainnya tidak membutuhkan perlakuan khusus maupun perlakuan pendahuluan seperti dengan menjemurnya atau membuatnya menjadi bagian-bagian dengan ukuran lebih kecil. Kesimpulan: Melalui penggunaan mesin pencacah bahan alami, produktivitas kompos meningkat menjadi 800 kg per hari dibandingkan sebelumnya hanya berkisar 100-200 jika menggunakan tenaga manual.

Abstract

One of the endemic plants of East Kalimantan, kapur (Dryobalanops aromatica) belongs to the Dipterocarpaceae family and is typically used by the locals for essential oils. Solid waste is only used as a natural fertilizer, while the leaves and bark of Kapur (Dryobalanops aromatica) are often only used for the essential oil extracted. Research on solid waste from distilling kapur (Dryobalanops aromatica) has never been done. This investigation aimed to find the possible concentration of secondary metabolite chemicals and antioxidants in the ethanol extract of solid waste from distilling Kapur leaves and bark (Dryobalanops aromatica). The ethanol extract of Kapur leaves and bark (Dryobalanops aromatica) will undergo phytochemical testing utilizing a qualitative test method to ascertain the presence of secondary metabolite chemicals. The ethanol extract of Kapur leaves and bark (Dryobalanops aromatica) will be tested for antioxidant activity against DPPH and ABTS free radicals using a UV Spectrophotometer. The results of the phytochemical analysis showed that the ethanol extracts from the leaves and bark contained alkaloids, flavonoids and tannin. Triterpenoids are only found in the bark extracts, while saponins and steroids are only found in the leaves extracts. Antioxidant activity of Dryobalanops atomatica extract showed that ethanol extract displayed an ability to inhibit DPPH free radical in both the leaves and bark ethanol extracts, with percentages of 83.24% and 94.91% at 25 ppm concentration, respectively. Antioxidant activity of Dryobalanops atomatica extract showed that ethanol extract could inhibit DPPH free radical in the leaves and bark ethanol extracts, with percentages of 83.24% and 94.91% at 25 ppm concentration, respectively.
