The production of grapes should be increased by using cuttings because the provision of seeds from seeds is relatively slow. Propagation of plants by cuttings is limited by the number of cuttings that form roots. This can be caused by a lack of root-forming hormones. As a substitute for synthetic auxin, onion can be used. This study aimed to analyze the effect of the concentration of shallot extract (Allium cepa L.) and soaking time on the growth of grape cuttings (vitis vinifera L.). The design used in this study was a factorial completely randomized design consisting of 2 factors. The first factor is onion extract which consists of 5 concentrations, namely 0, 25, 50, 75, and 100% shallot extract and the second factor is soaking time which consists of 4 levels, namely 6, 12, 18 and 24 hours so that there are 20 treatments. , each treatment was repeated 3 times. Parameters observed in this study were number of roots, shoot length, number of leaves, root length, percentage of live cuttings, wet weight and dry weight of the plant.

The method used in this research is the DPPH method. Based on the results of the study, it can be concluded that the temperature of 31.6°c in young leaves according to calculations is categorized as a strong antioxidant because it provides a calculated value of 82.778 ppm and 165.093 ppm on old leaves and classified as moderate antioxidants, while temperature of 44°c give dominant level under 31.6°c with IC50 values 123.78 ppm for young leaves and 165.170 ppm for old leaves and classified as moderate antioxidants according to the theory that compounds that have very strong antioxidant activity values IC50 values are less than 50 ppm, strong if the IC50 are between 50 and 100, moderate antioxidant if the IC50 values are feasible 100-250 ppm, weak if the IC50 value is 250-500 ppm and inactive if the IC50 value is more than 500 ppm. and vice versa related to the selection of leaf age also affects the level of antioxidant activity seen from the comparison of results from the two treatments that young leaves have a higher level of antioxidant activity than old leaves in counteracting free radicals.Keywords : Temperature, Antioxidant, Olive (Olea europaea L.), DPPH.ABSTRAKPenyebab penyakit degeneratif disebabkan karena aktivitas dan pola hidup yang kurang sehat. Pola hidup kurang sehat yang pada akhirnya memicu radikal bebas. Radikal bebas adalah molekul yang tidak teroksidasi yang menyebabkan terbentuk molekul baru yang dapat merusak sel tubuh. Radikal bebas dapat diatasi dengan pemberian antioksidan salah satunya dari tumbuhan zaitun (Olea europaea L.). Tujuan dari penelitian ini adalah untuk mengetahui pengaruh perlakuan suhu terhadap aktivitas antioksidan pada daun zaitun berdasarkan umur daun melalui perhitungan nilai IC50. Metode yang digunakan dalam penelitian ini adalah metode DPPH. Berdasarkan hasil penelitian dapat disimpulkan bahwa perlakuan suhu 31.6°C pada daun muda  menurut perhitungan IC50 dikategorikan sebagai antioksidan kuat karena memberikan nilai hasil perhitungan IC50  sebesar 82.778 ppm dan 165.093 ppm pada daun tua dan tergolong antioksidan sedang, sementara pada perlakuan suhu 44°C memberikan pengaruh lebih rendah dibandingkan dengan perlakuan suhu 31.6°C dengan nilai IC50 sebesar 123.78 ppm untuk daun muda dan 165.170 ppm untuk daun tua dan tergolong antioksidan sedang sesuai teori bahwa senyawa yang memiliki nilai aktivitas antioksidan sangat kuat jika nilai IC50 kurang dari 50 ppm, kuat apa","PeriodicalId":346598,"journal":{"name":"Jurnal SAINS ALAMI (Known Nature)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130352785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The potential for methane gas for fuel that has been used is currently around 3% to 5% of the existing potential. Based on information from the Department of Hygiene and Landscaping, Malang City Government has provided gas connection pipes including stoves for free to 59 houses in 2012 and 408 houses in 2013. This study uses tools and materials, namely questionnaires to obtain perception data from the public or respondents, digital cameras for documentation, documents on the use of methane gas at the Talangagung TPA, and stationery. The results of interviews with biogas managers show that the management of organic waste into methane gas is an alternative gas (biogas) used by the community in the TPA (Final Disposal Site) Kepanjen Malang Regency This is applied based on an energy utilization system (energy waste). Based on the results of the Percentage Graph, it states that the percentage of people's perceptions who answered the questionnaire on average showed strong or very high scores, very high and/or very strong scores were almost indicated in all respondents' answers.Keywords: Methane Gas, Perception, Talangagung LandfillABSTRAKPotensi gas metan di TPA dapat menjadi sumber energi terbarukan untuk memenuhi kebutuhan energi penduduk Kota Malang. Potensi gas metan untuk bahan bakar yang sudah dimanfaatkan saat ini sekitar 3% sampai 5% dari potensi yang ada. Berdasarkan keterangan dari Dinas Kebersihan dan Pertamanan Kota Malang, Pemerintah Kota Malang sudah memberikan pipa sambungan gas termasuk kompornya secara gratis kepada 59 rumah pada tahun 2012 dan 408 rumah pada tahun 2013. Penelitian ini menggunakan alat dan bahan yaitu kuesioner untuk mendapatkan data persepsi dari masyarakat atau responden, kamera digital untuk dokumentasi, dokumen pemakaian gas metan di TPA Talangagung dan alat tulis. Hasil wawancara dengan pihak pengelola biogas menunjukkan bahwa pengelolaan sampah organik menjadi gas metana sebagai gas alternatif (biogas) yang digunakan oleh masyarakat di TPA (Tempat Pembuangan Akhir) Kepanjen Kabupaten Malang ini di terapkan berdasarkan sistem pemanfaatan energi (waste to energy).
