Abstract

Benih kakao termasuk benih rekalsitran yang memiliki beberapa kendala seperti kadar air yang tinggi, tidak tahan desikasi dan suhu rendah, serta mudah terserang jamur sehingga menyebabkan benih tidak dapat disimpan dalam jangka waktu yang lama. Pada kondisi kadar air benih yang tinggi, perombakan cadangan makanan terjadi pada benih melalui proses respirasi benih juga tinggi yang menyebabkan terjadinya penurunan mutu benih akibatnya viabilitas dan vigor benih juga menurun. Penelitian ini bertujuan untuk mengetahui pengaruh pelapisan benih kakao dengan gel lidah buaya terhadap viabilitas dan vigor benih, dan mendapatkan konsentrasi gel lidah buaya yang mampu mempertahankan vigor dan viabilitas benih kakao selama penyimpanan. Penelitian dilaksanakan pada bulan Maret hingga Mei 2019 di Laboratorium Kampus III Universitas Andalas, Dharmasraya. Penelitian ini disusuan dalam Rancangan Acak Lengkap (RAL) dengan perlakuan beberapa konsentrasi gel lidah buaya yakni 0%, 25%, 50%, dan 75%. Setiap perlakuan tersebut diulang sebanyak 3 ulangan. Berdasarkan penelitian yang sudah dilakukan diketahui bahwa pelapisan benih dengan gel lidah buaya tidak berpengaruh terhadap viabilitas dan vigor benih kakao.

Abstract

Sorghum is one of the alternative food crop that can be developed as an effort for food diversify.One of the efforts that can be done for the development of sorghum is by using several genotypes and planting distance. This study aims to determine the growth and yield of several genotypes of sorghum at various planting distances. The research was carried out at the Experimental Garden of the Faculty of Agriculture, Andalas University, Padang, from January to May 2022. This study used an experimental method with a Randomized Block Design (RBD) consising of 2 factors. The first factor was the planting distance of the plants which consist of three levels, namely 70 cm x 10 cm, 70 cm x 20 cm and 70 cm x 30 cm. The second factor was the genotype which consist of three genotypes, namely genotype 76-1, genotype 103-1 and Bioguma5Agritan genotype. The data were analyzed by F test and if the calculated F value is greater than F table 5%, then it is continued with the Duncan’s New Multiple Range Test (DNMRT) at the 5% level. The results showed that the genotypes produced the same growth and yield. Planting distance of 70 cm x 30 cm had the best effect on stem diameter, panicle lenght, panicle fresh weight, dry seed weight per panicle and 1000 seed weight.

Abstract

The germination process is the key to plant phenology, which significantly influences the success of early plant growth. Some seeds have a dormancy, so the germination process is hampered or does not occur. However, dormancy-breaking treatments in plants have been widely reported, such as breaking the dormancy of sugar palm seeds through physical scarification. This research aims to determine the best scarification position to break the dormancy of sugar palm seeds. This research was carried out at the Seed Technology Laboratory, Faculty of Agriculture, Universitas Andalas from July to October 2023. The design was completely randomized with scarification in two position variations, the operculum (A1) and dorsal (A2) points, repeated thrice. The results showed that the position of seed scarification affected the emergence time of cotyledon petioles and coleoptiles, germination capacity, and seed moisture content. Scarification at the operculum point requires a dormancy break of 16 DAP (Days After Planting) compared to 29 DAP for the dorsal. Seed viability was good in seeds sacrificed at the operculum point, with a germination percentage of 81.94%. Keywords: dorsal, operculum, cotyledon petiole

Abstract

Upland rice is a type of rice that contributes to national rice production, but production is still categorized as low. Several problems in cultivating upland rice, such as the use of seeds produced from previous plantings and cultivation of upland rice plants which are still carried out once a year or once in one planting season, cause the seeds to undergo storage. Stored seeds have the potential to experience deterioration, which can reduce the quality of the seeds so that ultimately the plants do not grow optimally and have the potential to reduce production. This research used a completely randomized factorial design (CRD) which consisted of two factors, namely the comparison of the composition of matriconditioning plus and the length of immersion in matriconditioning plus. The combination treatment of the ratio of seed composition: rice husks ash: Trichoderma harzianum suspension (9:6:8) and soaking for 18 hours gives the best result because it can increase the maximum growth potential of the seeds to 98%, reduce the percentage of attack by pathogenic fungi to 11,67%, and have a higher test index value than other combinations. Key-words: Upland rice, seed deterioration, matriconditioning plusINTISARIPadi gogo merupakan salah satu jenis padi yang menyumbang produksi padi nasional, namun produksi masih dikategorikan rendah. Beberapa permasalahan dalam budidaya padi gogo seperti penggunaan benih yang diproduksi dari pertanaman sebelumnya dan budidaya tanaman padi gogo masih dilakukan sekali dalam setahun atau satu kali musim tanam menyebabkan benih telah mengalami penyimpanan. Benih yang disimpan berpotensi mengalami deteriorasi, sehingga dapat menurunkan mutu benih hingga akhirnya tanaman tidak tumbuh optimal dan berpotensi menurunkan produksi. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) Faktorial yang terdiri dari dua faktor, yaitu perbandingan komposisi dan lama perendaman benih dalam matriconditioning plus. Kombinasi perlakuan perbandingan benih: abu sekam padi: suspensi Trichoderma harzianum (9:6:8) dan perendaman benih selama 18 jam memberikan hasil terbaik karena dapat meningkatkan potensi tumbuh maksimum benih menjadi 98%, menurunkan persentase serangan jamur patogen menjadi 11,67% dan memiliki nilai uji indeks yang lebih tinggi dibandingkan kombinasi lainnya. Kata kunci: Padi gogo, deteriorasi benih, matriconditioning plus

Abstract

Intensive cultivation of Aren (Arenga pinnata Merr.) is needed because of its high potential in meeting the needs of food diversification in particular. Aren palm plants that have been cultivated also experience problems in the nursery phase and transfer to the field. In natural environmental conditions, aren palm requires shade to grow well. However, research on the effect of shade and planting media in the nursery phase has never been conducted. This study used a completely randomized design (CRD) with two factors arranged according to a split-plot design (RPT). The first factor or main plot is the level of shade. The second factor or subplot was planting media. There was an interaction between shade and planting media on the growth of sugar palm seedlings. The 55% shading level and soil + husk charcoal planting media gave the best interaction on the variable of time to first leaf appearance, leaf blade width, plant fresh weight, root fresh weight.  Key-words: Sugar palm, shade, planting mediaINTISARIBudidaya Aren (Arenga pinnata Merr.) secara intensif sangat diperlukan karena berpotensi tinggi dalam memenuhi kebutuhan diversifikasi pangan khususnya. Tanaman aren yang telah dibudidayakan juga mengalami kendala pada fase pembibitan dan pemindahan ke lapangan. Pada kondisi lingkungan alami, aren membutuhkan naungan untuk dapat tumbuh dengan baik. Namun, penelitian mengenai pengaruh naungan dan media tanam pada fase pembibitan belum pernah dilakukan.

Abstract

This study aims to determine the appropriate paranet shade intensity and organic planting media combination for vanilla cuttings. The experiment was designed using a Split-Plot Design within a Completely Randomized Design. The shade intensities used are 50% and 70% of paranet. The organic planting media combinations are soil + compost + rice husk, soil + compost + cocopeat, soil + goat manure + rice husk, and soil + goat manure + cocopeat (in a 2:2:1 ratio, w/w). Data was analyzed using a F-test, followed by Duncan’s New Multiple Range Test at a significance level of 5%. The results indicate no interaction between paranet shade intensity and planting media combination. The 70% paranet shade intensity yields the best outcomes in terms of live cutting percentage (100%), shoot length (20.32 cm), internode length (3.24 cm), number of internodes (6.07), and leaf count (6.07 leaves). While different planting media may not significantly.

Abstract

The village of Sungai Nanam, Lembah Gumanti, is an area in Solok Regency, West Sumatra, that produces significant organic waste from horticultural agriculture. If not managed properly, this waste can cause environmental and aesthetic issues. However, this waste can be converted into an eco-enzyme. An eco-enzyme is a liquid enzyme produced by fermenting organic waste. Eco-enzyme has many benefits, including being used as a liquid organic fertilizer, cleaner, and pest repellent. This community service aims to educate and train the community, especially the women farmers group, named Kelompok Wanita Tani (KWT) Rimbo Data Sejahtera, on converting organic waste into eco-enzymes. The program used three methods: socialization, demonstration, and mentoring. It has been proven to be an effective way to educate and train the community, particularly KWT Rimbo Data Sejahtera, on proper waste management. This program is a perfect fit for their needs and is very useful in reducing the impact of pollution.

Abstract

Dry gambier extract obtained from gambier plants contains tannins at relatively low levels. Tannins can be obtained by extracting dry gambier using water to achieve high yields within a relatively short processing time. This study aims to analyze the interaction between extraction time and microwave power in the tannin extraction process from gambier using the microwave-assisted extraction (MAE) method to maximize tannin yield.  The research method employed was a factorial design (AxB). Factor A was extraction time, consisting of five treatments (1; 2; 3; 4; and 5 minutes) and factor B was microwave power, consisting of five variations (180W; 300W; 450W; 600W and 850W). The results showed that the gambier extraction process using MAE demonstrated an interaction between extraction time and microwave power on the yield produced, but not on the tannin content. The most optimal temperature and power that can be used is 4 minutes at 600W microwave power with a yield of 44.66%. The treatment of temperature and microwave power in the gambier extraction process showed a significant interaction with the extract yield.

Abstract

SummaryAttempts to improve productivity of cacaoplantations lead us to study the molecularmechanism of flowering. In the model speciesArabidopsis thaliana as well as some otherspecies, LEAFY is a central regulatory gene forthe transition of shoot apical meristems toflowering meristems. Different from that ofArabidopsis, cacao inflorescence is acauliflorous type, by which flowers can developrepeatedly from the same flower cushion on thetrunk. In this research, a LEAFY homolog wasisolated from active flower cushion with RT-PCRusing a pair of DNA primer specifically designedto isolate its complete cds. Gel electrophoresisexamination indicated the presence of a 1.2 kbamplicon. Purified from the gel, this DNAfragment was cloned into competent cells ofE. coli XL1 Blue using pGEM-T Easy cloningvector at an orientation according to the T7promoter of the plasmid. Sequence analysis usingBLASTX, showed that the amplicon was LEAFY(LFY) homolog. Alignment analysis using ClustalW indicated that the cTcLFY highly homologousto those from other perennial crops such ascitrus, grape, apple and poplar. The highesthomology (conserved region) was found in the Cterminal of the encoded proteins.RingkasanUsaha untuk meningkatkan produktivitasperkebunan kakao telah mendorong penelitianmolekuler tentang mekanisme pembungaankakao. Pada tanaman model Arabidopsis thalianadan lainnya, LEAFY merupakan gen kunci dalamtransisi meristem tunas jadi meristem bunga.Berbeda dengan sistem pada Arabidopsis,pembungaan kakao termasuk tipe cauliflorous,bunga dapat muncul dari bantalan bunga yangsama sepanjang tahun. Dalam penelitian inihomolog LFY diisolasi dari bantalan bunga aktifmenggunakan RT-PCR dengan sepasang primerspesifik yang dirancang berdasarkan sekuenDNA di kedua ujung gen tersebut. Pemeriksaangel elektroforesis menunjukkan adanya amplikontunggal berukuran 1,2 kb.
