Seedlings is the initial part of seed plant’s growth and development including areca nut palm which germination is an essential part of it. Organic mulching is one of the utmost sustainable practices, therefore, it has been employed to enhance areca nut seedlings growth. The study aims to evaluate the effect of several types of organic mulch on areca nut seedlings shoot-root growth. The 3-month long experiment was conducted according to completely randomized design, with four treatments, namely no mulching (control) (M0), gliricidia (<em>Gliricidia sepium</em>) mulching (M1), imperata (<em>Imperata cylindrica</em>) mulching (M2) and <em>lamtoro</em> (<em>Leucaena leucocephala</em>) mulching (M3). The treatments were repeated 5 times with 20 experimental units. The findings revealed that no significant differences (p < 0.05) were found on the application of different organic mulching among all of the parameters. The treatment covered by imperata mulch tended to score the highest compared to other mulches on germination time, seedling height and shoot fresh weight while the minimum yield was recorded in M1 where gliricidia mulch was used. Application of organic mulch displayed better results for most of the parameters than that of the control resulting from an optimal growing environment for areca nut seedlings growth.
This study aims to describe the capacity of students' learning skills, provide and develop problem-solving learning skills, prepare appropriate modules that are used by students, and encourage counseling and learning development units. The method used in this action research is a qualitative research design. The research technique was carried out by using a case study approach and observation. The results showed that the students' mathematical abilities ranged from 26-50 (57.14%). Only 14% (11.43% + 2.86%) of AgtSP students have capacities in basic mathematics. Learning skills, for example, reading and writing, had lower AgtSP values, namely 37.14% and 34.29%. AgtSP is still dominated by Papuan students (86%) and a small proportion of non-Papuan students (14%). Many students enrolled in AgtSP graduated from Social Sciences (38%), some graduated from Agricultural High School (33%), and a few graduated from natural sciences 21%) and a small number of students graduated from Non. Agricultural Senior High School, namely administration interest. Student GPA has increased in the number of students who have GPA scores. 23 components affect student learning skills at the university level as experienced by AgtSP. The conclusion is the low scores obtained by mathematics, reading, and writing students enrolled in the Faculty.
Organic fertilizers have been considered as environmentally friendly fertilizers in promoting sustainable agriculture, being supported by the abundant natural resources. The study was conducted to determine the effect of type and level of dosage of organic fertilizers on soybean yield. The 4-month study was carried out in West Papua Province, Indonesia, compiled using factorial randomized block design (RBD). The factors were the types of organic fertilizer and two doses of the organic fertilizer. Parameters assessed include number of grains per pod, weight of 100 grains and weight of grains per plot. Pointed out the results of the analysis of variance, the various types of organic fertilizers used (F1, F2, F3 and F4) were significantly different in almost all components of growth and production. However, the type of goat manure (F4) gave the highest yield, while the type of fertilizer that gave the lowest yield was compost (F2). Fertilizer doses were significantly different in almost all yield parameters, namely D1 (5 tons/ha) compared to D0 (without fertilizer). The interaction with the highest yield was goat manure (F4D1), while the interaction that gave the lowest yield was without the use of compost fertilizer (F2D0). Given that high soybean yield can be achieved by balanced fertilization. One way to increase soil fertility in terms of providing nutrients for plants and harmless toward land and plant is by providing organic fertilizers.
<em>Radish (Raphanus sativus L.) is popular in the world as a root vegetable. In Indonesia, the yield of radish is low due to several factors such as the cultivation system. Fertilization and mulching are among the cultivation system which are widely known to improve crop growth and yield. The research aimed to study the effect of bokashi-fertilizer and mulch combination on yield of radish (Raphanus sativus L.). A field experiment was conducted at the Experimental Garden of Agriculture and Agricultural Technology Faculty, The State University of Papua, Manokwari. This experiment was set up in a randomized block design, consisting of three kinds of bokashi namely firewood/ashwood-bokashi (B1), firewood-bokashi (B2), ashwood-bokashi (B3) and four kinds of mulches consist of transparent plastic mulch (M1), black/silver plastic mulch (M2), gliricida mulch (M3) and imperata mulch (M4). The overall treatments were as follows: control, B1M1, B1M2, B1M3, B1M4, B2M1, B2M2, B2M3, B2M4, B3M1, B3M2, B3M3, B3M4. The results show that yield of radish was not affected by application of the bokashi and mulch combination. Even though, no statistically significant, the application of bokashi and mulch increased plant fresh weight by 59%, tuber fresh weight per plant 61.28%, leaf weight 45.79%, tuber length 19.38% and tuber diameter 22.38% compared to control.</em>
Kekayaan sumber daya genetik di Provinsi Papua, dengan beragam potensinya, belum dikaji dan dimanfaatkan secara berkelanjutan agar erosi genetik yang terjadi terhadap plasma nutfah dapat dikurangi dan dicegah. Dengan demikian, pengelolaan plasma nutfah yang optimal merupakan bagian tak terpisahkan dalam upaya menjaga sumber daya genetik agar tetap lestari. Salah satunya adalah tanaman gembili yang memiliki nilai budaya yang tinggi karena digunakan dalam upacara adat dan juga digunakan sebagai maskawin pernikahan dan sebagai pelengkap dalam upacara adat. Hal ini berarti, budidaya tanaman gembili sudah menyatu dalam kehidupan masyarakat Papua. Penelitian ini bertujuan untuk menguji beberapa media air terhadap respon pertumbuhan tunas dan akar tanaman gembili sebagai salah satu teknik budidaya untuk memperpendek masa dormansi dan menghasilkan bahan tanam atau bibit gembili asal Serui Papua. Penelitian dilakukan selama 2 bulan menggunakan metode Rancangan Acak Lengkap (RAL) yang terdiri dari 2 perlakuan yaitu perendaman dengan air aqua/air steril dan air sumur, perlakuan diulang sebanyak 3 kali sehingga diperoleh 6 satuan percobaan. Dari hasil pengamatan dapat disimpulkan bahwa dengan menggunakan teknik budidaya perendaman umbi dengan air steril atau air aqua dapat memperpendek masa dormansi dan memperbanyak bahan tanam atau bibit gembili (Dioscorea esculenta L.) asal Serui Papua. Hasil analisis data membuktikan pemberian media air memberikan pengaruh yang nyata dalam pertumbuhan tunas dan akar pada umbi gembili. Perbandingan perlakuan air aqua dan air sumur menunjukkan konsistensi dimana perlakuan air aqua mengekspresikan rata-rata jumlah tunas dan jumlah akar pada 4 MST, lebih banyak dibandingkan rata-rata kedua parameter pada perlakuan air sumur pada 5 MST. Direkomendasikan untuk penelitian lanjutan menggunakan perlakuan yang sama dan alternatif media tanam air lainnya dengan memperpanjang waktu pengamatan.
