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

Secara historis masyarakat Dayak Bulusu tidak bisa dilepaskan dari sumber daya hutan. Secara ekonomi, lahan hutan menjadi tempat masyarakat berladang yaitu pertanian pada lahan kering dengan sistem gilir balik, menggunakan kearifan lokal dan tahapan perladangan yang dipraktekkan secara turun temurun. Fenomena perubahan iklim yang terjadi saat ini berdampak terhadap makhluk hidup dan lingkungan, termasuk ancaman bagi pertanian masyarakat. Penelitian ini bertujuan untuk mengkaji kalender musim perladangan dalam 1 periode tanam di tengah masa perubahan iklim dan peran gender dalam perladangan. Penelitian ini dilakukan di Desa Pungit Kecamatan Sekatak Kabupaten Bulungan Kalimantan Utara pada Bulan Juli-Agustus 2022. Pengambilan data dilakukan dengan teknik triangulasi yaitu FGD, observasi lapangan dan kajian literatur. Analisis data dilakukan secara deskriptif kualitatif. Kegiatan berladang Dayak Bulusu Desa Pungit Sekatak dilakukan dengan tahapan tertentu dimulai dari tahap pemilihan lokasi berladang dan penebasan pada Bulan Mei; penebangan dan pemotongan dahan ranting pada bulan Juni; pengeringan selama bulan Juni-Juli; pembakaran pada bulan kering yaitu Bulan Agustus-September; penanaman dilakukan Bulan September-Oktober dimana sudah mulai musim hujan; pemeliharaan yaitu setelah masa tanam hingga memasuki Bulan Pebruari yang dilanjutkan dengan pemanenan hingga bulan Maret. Laki-laki dan perempuan berperan penting dalam setiap tahap kegiatan berladang sesuai dengan porsi dan perannya masing-masing.

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

Penelitian ini dilatarbelakangi oleh belum maksimalnya penggunaan salah satu tumbuhan hutan yang berkhasiat bagi kesehatan. Salah satu jenis tumbuhan hutan yang telah dilakukan pengujian adalah daun dan batang tumbuhan ngaung dan hasilnya menunjukkan bahwa tanaman ngaung memiliki manfaat bagi kesehatan. Oleh karena itu tujuan dari penelitian ini adalah untuk mengetahui aktivitas antioksidan, aktivitas antibakteri terhadap bakteri Escherichia coli, Streptococcus mutans dan Propionibacterium acne, serta untuk mengetahui kandungan fitokimianya yaitu flavonoid, alkaloid, tannin, saponin, triterpenoid dan steroid dan mengetahui toksisitas pada bagian akar pada tanaman ngaung (Ficus obscura Blume). Hasil penelitian menunjukkan bahwa pada pengujian aktivitas antioksidan dengan nilai IC50 pada ekstrak kulit akar ngaung adalah 19.82 ppm dan pada kayu akar ngaung adalah 14.332 ppm. Daya hambat terbesar pertumbuhan bakteri Proponibacterium acne adalah pada kulit akar konsenstrasi 100 µg/well  yaitu 8,88 mm sedangkan kayu akar penghambatan terbesar pada konsentrasi 200 µg/well  dengan penghambatan 8,66 mm. Daya hambat terbesar pertumbuhan bakteri Escherichia coli adalah pada konsentrasi 400 µg/well  yaitu sebesar 10 mm pada kulit akar dan 9,99 pada kayu akar. Hasil pengujian pada sampel uji memiliki kandungan senyawa fitokimia flavonoid, tanin, alkaloid dan triterpenoid pada kulit akar Ngaung sedangkan pada kayu akar Ngaung didapatkan senyawa flavonoid, saponin, tanin, saponin dan triterpenoid. Hasil pengujian toksisitas ekstrak kulit akar maupun kayu akar menunjukan bahwa senyawa bersifat tidak toksik.

Abstract

Project-based learning (PBL) has been increasingly adopted in vocational higher education as a pedagogical approach that integrates technical skill development with interpersonal competency formation. However, the role of cultural and religious character values in shaping student cooperation within PBL environments remains underexplored, particularly in the Indonesian vocational context. This research examines how Islamic character values, namely amanah (trustworthiness), ta'awun (mutual assistance), and musyawarah (deliberation), were expressed and reinforced within the PBL structure implemented in the Wood Engineering study at Politeknik Pertanian Negeri Samarinda, and how this contributed to the development of student cooperation skills. A qualitative descriptive case study was employed, involving 44 fourth-semester students in eleven working groups across multiple wood engineering courses. Data were collected through structured in-depth interviews, participatory observation across 32 sessions, eleven focus group discussions, and document analysis. Thematic analysis following Braun and Clarke six-phase framework was applied, with inter-rater reliability of Cohen Kappa 0.86. Findings suggest that the project structure created favorable conditions for the expression and reinforcement of these character values, though the degree of internalization varied considerably across groups and individual students. The study contributes an empirically grounded illustration of how Islamic character values and cooperative behavior interact within authentic vocational project work, while acknowledging the context-specific nature of the findings
