Abstract

Procurement of quality seeds and seedlings quickly available for consumers in sugar palm plantations still has many obstacles. Sugar palm seeds take a long time to germinate due to the dormancy period. One effort that can be done is scarification physically and chemically, including using gibberellins. This study aimed to determine the effect of scarification treatment and various concentrations of gibberellin (GA3) on breaking dormancy and germination of sugar palm seeds. This research was carried out in the Seed Technology Laboratory, Faculty of Agriculture, Andalas University, from March to August 2022. The design was used by completely randomized design (CRD) in factorial 3x4x3. The first factor was the scarification technique which consisted of three levels with using sandpaper, hand grinding, and sitting grinding. The second factor was soaking the seeds in GA3 solution with four levels which consisted of 0 ppm, 50 ppm, 100 ppm, and 150 ppm. The results of this reseach showed that the seed scarification technique had effected on the seeds water content and the electrical conductivity of the sugar palm seeds, while seed scarification and gibberellin immersion had effected the dormancy time of the sugar palm seeds, but it didnot effect the germination ability of the sugar palm seeds. Seed scarification used a sitting grinding machine and gibberellins with concentration of 100 ppm would have efficiented the fastest breaking dormancy of sugar palm seeds in 18.67 days.INTISARIPengadaan benih bermutu dan bibit yang cepat tersedia bagi konsumen pada tanaman aren masih memiliki banyak kendala. Benih tanaman aren memerlukan waktu yang cukup lama untuk berkecambah yang disebabkan terjadinya masa dormansi. Salah satu upaya yang dapat dilakukan adalah dengan melakukan skarifikasi secara fisik dan kimia diantaranya dengan penggunaan giberelin. Tujuan penelitian ini adalah untuk mengetahui pengaruh perlakuan skarifikasi dan berbagai konsentrasi giberelin (GA3) terhadap pematahan dormansi dan perkecambahan benih aren. Penelitian ini telah dilaksanakan di Laboratorium Teknologi Benih Fakultas Pertanian Universitas Andalas pada bulan Maret hingga Agustus 2022. Rancangan yang digunakan adalah rancangan acak lengkap (RAL) dalam faktorial 3x4x3. Faktor pertama adalah teknik skarifikasi yang terdiri dari tiga taraf yaitu menggunakan kertas amplas, gerinda tangan dan gerinda duduk dan faktor kedua adalah perendaman benih dalam larutan GA3 dengan empat taraf yaitu: 0 ppm, 50 ppm, 100 ppm dan 150 ppm. Hasil penelitian menunjukkan bahwa teknik skarifikasi benih berpengaruh terhadap kadar air benih dan daya hantar listrik benih aren, sedangkan skarifikasi benih dan perendaman giberelin berpengaruh terhadap waktu patah dormansi benih aren, namun tidak mempengaruhi daya berkecambah benih aren. Skarifikasi benih menggunakan mesin gerinda duduk dan giberelin konsentrasi 100 ppm menghasilkan waktu pematahan dormansi benih aren tercepat yaitu 18,67 hari.

Abstract

One of the limiting conditions for shallot plants to grow optimally is dry land conditions. Indigenous AMF application is one way to overcome this condition. This study aimed to determine the effect of indigenous AMF application on the morpho-physiological characters of two shallot varieties which are sensitive and tolerant to drought stress conditions. The study was carried out for 6 months on a wirehouse and laboratory scale. The Experiment used a completely randomized design with two factors. The first factor was varieties of shallots, i.e. Brebes (Sensitive) and Kuning (Tolerant) varieties of shallots. The second factor was the application of indigenous AMF which consisted of 5 levels i.e. Glomus sp1, Glomus sp2, Glomus sp3, a mixed those three isolates and control treatment (without application of AMF). The morpho-physiological observation parameters included header dry weight, root weight, and leaf proline content. From the observations, it can be concluded that under stressed conditions, the leaf proline content of the sensitive variety accumulated higher in the header than the tolerant variety, because the tolerant variety was better able to produce higher root and header weights when adapting than the sensitive. AMF inoculation did not show significant differences with the treatment without AMF inoculation on leaf proline. However, there was a tendency that inoculation of a mix of AMF isolates (Glomus sp1+Glomus sp2+ Glomus sp3) decrease the proline content in the leaves, both in sensitive and tolerant varieties so that plants are more resistant to drought stress.

Abstract

The application of true shallot seed cultivation technology with the planting spacing and number of seedlings per planting hole is expected to increase the productivity of shallots in Indonesia. The research was carried out at KP Sukarami-AIAT West Sumatra from January to June 2021. The aim of the study was to obtain recommendations for the appropriate planting spacing and number of seedlings per planting hole in increasing the growth and yield of true shallot seed in West Sumatra. The study used a 2-factor factorial design in a randomized block with 3 replications. The first factor is the planting spacing (JT), which consists of 3 types, namely: JT1 (10 cm x 10 cm), JT2 (10 cm x 15 cm), and JT3 (15 cm x 15 cm). The second factor is the number of seedlings per planting hole (JB) which consists of 5 types, namely: JB1 (1 seedling), JB2 (2 seedlings), JB3 (3 seedlings), and JB4 (4 seedlings). The results showed that there was not significant interaction between the planting spacing and the number of seedlings per planting hole on the yields of true shallot seed. The highly significant interaction was only found in the growth components and yield components. The best planting spacing is 10 cm x 10 cm and 10 cm x 15 cm, while the best number of seedlings is 1-2 seedlings per planting hole. It is recommended to use a planting spacing of 10 cm x 10 cm or 10 cm x 15 cm with 1-2 seedlings per planting hole in true shallot seed in the highlands of West Sumatra.

Abstract

Conductivity test is a test to physically measure the electrolyte leaking from seeds and be classified as vigor test. However, some factors may affect the result of the test; therefore, standardized procedures should be defined for its accuracy and consistency. The research reported here was aimed at obtaining specific method of conductivity test for wheat seeds and to study the correlation between conductivity test result with seed germination and field emergence. The experiments were conducted at the laboratory of BBPPMBTPH, Cimanggis, Depok from February to June 2013. The experiment was designed to identify the correct amount of wheat seeds and the volume of water used to soak the seeds. The experiment was assigned according to a completely randomized design (CRD) with 20 wheat seed lots and three replicates. Data collected including seed germination (SG), vigor index (IV) or First Count Test (FCT), field emergence (FE) at 8, 14, and 21 days, tetrazolium test (TZ), and conductivity test for nine combinations of wheat seed amount and the water volume for soaking (50, 75, and 100 seeds in 100, 150, and 200 mL of water). Results show that soaking 75 wheat seeds in 200 mL of water was best for conductivity test. This soaking condition resulted in negatively significant correlation between seed germination and field emergence. Moreover, low value of conductivity resulted in high values of SG, IV, FE, and TZ. Wheat seed germination and field emergence can be estimated using the equations of y = 0.028x2 – 3.321x + 104.9 and y = 0.022x2 – 2.704x + 87.96, respectively.

Abstract

The process of making domestic chicken egg white flour can be done by drying using an oven at 105 0C. To avoid the Maillard reaction, fermentation was carried out with Rhizopus sp. first. In this study, Rhizopus sp. concentrations of 0.2 %, 0.4 %, 0.6 %, 0.8 % and fermentation times of 6 hours, 12 hours and 24 hours were used. The aim of the research was to analyze the effect of the concentration of Rhizopus sp. yeast and the length of fermentation time on the characteristics of the egg white flour produced. The results showed that the concentration of Rhizopus sp. yeast and the length of fermentation time had an effect on the yield of egg white flour (P<0.05). The highest yield was obtained from using a concentration of 0.8 % and a fermentation time of 24 hours, namely 14.40 %. The lowest water content value was obtained from using a concentration of 0.2 % and a fermentation time of 6 hours, namely 5.66 %. The highest brightness test value was at a concentration of 0.8 % and a fermentation time of 24 hours, namely 63.4 %..

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

Kegiatan penambangan memberikan nilai keuntungan ekonomi yang cukup besar bagi suatu negara, salah satunya tambang batu bara. Akan tetapi, dampak kerusakan lingkungan yang ditimbulkan juga relatif besar. Upaya revegetasi lahan dapat dicapai antara lain dengan penggunaan fungi mikoriza arbuskular (FMA). Penelitian ini bertujuan untuk memperoleh FMA indigen dari lahan bekas tambang batu bara di Kecamatan Talawi, Kota Sawahlunto untuk dikembangkan sebagai sumber inokulum, sehingga dapat diaplikasikan dalam upaya revegetasi lahan. Penelitian dilakukan dengan mengambil sampel tanah dari lahan bekas tambang batu bara sebanyak sepuluh titik yang dibedakan menjadi lima macam tipe kelerangan yaitu datar, landai, curam, agak curam, dan sangat curam. Hasil analisis tanah menunjukkan bahwa lahan bekas tambang batu bara tergolong tanah marginal dengan tingkat kesuburan rendah ditandai dengan dominasi fraksi pasir, pH rendah, kadar hara P, N, K, Ca, Mg, dan KTK yang rendah serta memiliki kandungan unsur logam Al dan Pb yang tinggi. Adapun dari lima kategori kelerengan ditemukan empat jenis spora FAM yaitu Glomus sp., Acaulospora sp., Gigaspora sp., dan Sclerocystis sp. Lereng datar memberikan jumlah spora tertinggi dibanding lereng lainnya. Glomus sp. memiliki kemampuan adaptasi yang lebih tinggi di semua tipe lereng dibandingkan jenis lain. Semakin tinggi pH dan kadar P dalam tanah, jumlah dan keanekaragaman spora akan semakin menurun. Sementara itu, semakin tinggi nilai KTK tanah, jumlah dan keanekaragaman spora akan semakin tinggi sampai batas optimal tertentu bergantung dari kemampuan adaptasi masing-masing spora FMA.
