Abstract

A study on desiccation sensitivity of rambutan (Nephelium lappaceum L.)excised embryo has been conducted.Excised embryos were desiccated into target moisture content of 30%, 25%, 20%, 15% and 10% respectively.Results shown that the critical level for moisture content was 20% with 60% viability and 7.431% per etmal growth rate and 929ms electric conduction Further study is needed as to investigate on how long the embryo will withstand subsequent storage treatments.

Abstract

Pandanus plant is one of the important plant in Papua and Papua New Guinea. Traditionally pandanus plant is used by local people for lots of daily activities and daily needs, start from food flavoring, medicine, to religious ceremony needs. Pandan kelapa hutan fruits (P. jiulianettii Martelli.) is one of a kind of pandanus that been used from generation to generation the highlands of Papua and Papua New Guinea for the food ingredients. This research aims to determine the physicochemical properties, total phenol, total carotene,vitamin E and antioxidant activities of the forest coconut pandan oil (P. jiulianettii Martelli.) extracted using an aluminum pan. Physicochemical character that been analyzed is specific gravity, iod value, saponification value, free fatty acid content, acid value and peroxide value. Total phenol, total carotene and vitamin E measured respectively using Folin-Ciocalteu method, spectrophotometry method and colorimetric methods. Antioxidant activities is measured using a method that called DPPH. The result shows the pandan coconut oil has 1,00059 of specific gravity, 65.87 g/100gr of iod, 201,28 mg/g of saponification, 4.26% of acid and 5.64 Meq/kg of peroxide. The content of total phenols, total carotene and vitamin E respectively are 48.55 ppm, 2.75 µg/g and 5.0303 mg/100g. The antioxidant IC50 measuring result shows the value is 45.83 mg/mL.

Abstract

Pembelajaran konvensional di dalam kelas sering dianggap oleh siswa sebagai sesuatu hal yang tidak menarik dan membosankan. Hal ini merupakan salah satu penyebab rendahnya motivasi dan hasil belajar peserta didik. Untuk mengatasi permasalahan tersebut, peneliti memanfaatkan lingkungan sekitar sebagai media untuk meningkatkan hasil belajar peserta didik dengan menerapkan model Problem Based Learning (PBL). Penelitian ini bertujuan untuk mengetahui peningkatan Penguasaan Konsep peserta didik dengan model PBL yang memanfaatkan media lingkungan pada materi keanekaragaman hayati (kehati). Metode penelitian menggunakan metode design single study yaitu desain penelitian dengan kasus tunggal. Populasi dalam penelitian ini yaitu seluruh siswa kelas X, SMAN 1 Arso dan SMAN 2 Skanto tahun ajaran 2018/2019 dengan jumlah total 125 siswa. Pengambilan sampel penelitian menggunakan tekhnik purposive sampling dan dilanjutkan dengan Cluster random sample (tekhnik sampel area). Hasil penelitian menunjukan adanya peningkatan hasil belajar peserta didik dengan menggunakan PBL. Hal ini terlihat dari nilai rata-rata peserta didik yang mengalami peningkatan. Nilai rata-rata pretest untuk kelas konvensional pada penguasaan konsep kehati adalah 30,3. Nilai rata-rata postest untuk penguasaan konsep kehati adalah 62.6. Nilai rata-rata pretest untuk kelas eksperimen pada penguasaan konsep kehati adalah 33,9. Nilai rata-rata postest untuk penguasaan konsep kehati adalah 75,4. Kesimpulan dari penelitian ini adalah bahwa Penggunaan model pembelajaran PBL dengan lingkungan sebagai media pendukung pembelajaran dapat meningkatkan hasil belajar peserta didik di SMA Kabupaten Keerom.

Telah dilakukan penelitian untuk mengetahui pemanfaatan pandan-pandanan oleh masyarakat Papua di   Kepulauan Yapen, Kabupaten Jayapura, Kabupaten Lanijaya, dan Kabupaten Jayawijaya. Metode penelitian yang digunakan adalah metode kualitatif dengan teknik wawancara,  observasi, dan studi pustaka, selanjutnya data dianalisis secara deskriptif. Hasil penelitian ditemukan 11 jenis pandan-pandanan yang dimanfaatkan oleh masyarakat Papua, yaitu Pandanus amarylifolius (Pandan wangi), Pandanus conoideus Lam., Pandanus tectorius Parkinson (Pandan tikar),  Pandanus leptocaulis Merr & Perry, Pandanus jiulianetii (Pandan kelapa hutan), Pandanus polycephalus Lam., Pandanus odoardi Martelli, Pandanus sp1., Pandanus sp2. P. kaernbachii Warb., dan Sararanga sinuosa Hemsley (Pandan anggur). Buah P. conoideus Lam. dikonsumsi sebagai sumber energi, dan sebagai bahan obat, sedangkan akarnya dimanfaatkan sebagai pengikat daun sagu untuk atap rumah.  Daun P.  leptocaulis Merr & Perry dimanfaatkan sebagai tikar jahit, akar P.  tectorius Parkison dimanfaatkan sebagai alat penangkap ikan,  pucuk tunas batang  P. polycephalus Lam. dimanfaatkan sebagai obat tradisional, daun P. kaernbachii Warb, dimanfaatkan sebagai pembungkus makanan,  daun P.  odoardi Martelli dimanfaatkan sebagai bahan baku anyaman piring, daun Pandanus sp.1 dimanfaatkan sebagai bahan baku anyaman piring  dan serat akar Pandanus sp. 2 dimanfaatkan sebagai  bahan benang untuk menjahit tikar, dan untuk pakaian adat. Seluruh organ Pandanus jiulianetii (pandan kelapa hutan) dapat dimanfaatkan. Buah dikonsumsi sebagai bahan makanan tradisional, daun dimanfaatkan untuk membuat tikar dan payung tradisional,  serat akar dimanfaatkan sebagai bahan dasar pembuatan tas atau noken dan anak panah, batang dapat dijadikan papan untuk lantai atau dinding.

Abstract

Gwinjaya is a village in Bonggo District, developed from the SP4 (Settelement Unit) transmingration settlement land in Bonggo district. The people mainly make their living as farmers and mostly grow peanuts and cultivating sago flour which comes from the sago plant. The abundant harvest has not yet been processed into food which has a higher selling value and is more durable. Through training in making biscuits made from sago flour and peanuts as well as sugar and spices , it is hoped that new etreprenuers can be formed with biscuit sago commodities. Tha training was carried out by demonstrating biscuit making and continued with participants trying to make biscuits. The resulting product was then tested organaoleptically to determine the quality and preference of the biscuits produced compared to biscuits sago sold on the market. The results of the activities that have been carried out show that the mothers in the village Gwinjaya, which is part of the Gwinjaya Village-Owned Enterprices , has been able to make biscuits made from sago flour well. The results of organoleptic testing produced with three other biscuit products on the market, showing that the respondents expressed their liking for the products they produced as seen from taste, smell, aroma and color parameters

Abstract

The natural resource processing industry in Jayapura has begun to show results, especially in the form of local food and medicine products. Local product-based industrial products that have not yet reached industry players in Jayapura, such as aromatherapy candle products with essential oil extracts from plants in Papua. Aromatherapy candles are generally used to provide aromatherapy where the aroma can refresh the body and some can also repel mosquitoes, depending on the essential oils mixed into the candle making ingredients. Making aromatherapy candles is not difficult, does not take long, the raw materials are cheap and have a high selling value compared to the price of the raw materials. Based on this, it is very potential to be used as a commodity for industry players who are just starting their business. The implementation of the training in collaboration with the Jayapura BUMN House fostered by BRI Jayapura Branch, so that for the formation of new entrepreneurs who want to develop it, it has been prepared with its business funders, it is hoped that they will be able to become Micro, Small and Medium Enterprises (MSMEs), who are reliable in the aromatherapy candle industry made from essential oils from Jayapura and its surroundings. The training was conducted by providing material that was carried out with demonstrations by students who had been drilled by instructors, followed by a trial of making aromatherapy candles carried out by training participants. Evaluation was carried out by organoleptic testing of the level of preference for the resulting product in terms of aroma, texture, color, appearance using a Likert scale with a scale of 5, namely (1) Dislike, (2) Less like (3), Somewhat like, (4) Like, and Really like (5). Training participants were able to make aromatherapy candles well and liked the aromatherapy candle products from the training results.
