Abstract

Citronella grass (Cymbopogon nardus L) is one of the essential oil-producing plants from the Gramineae group. This research was conducted in the Greenhouse of the Faculty of Agriculture, Andalas University, Padang from August 2017 until January 2018. This study aimed to determine the effect of Acaulospora sp and different water treatments on the growth of citronella grass in ultisol. A completely randomized design with two factors was used. The first factor was treatment with or without Acaulospora sp. The second factor was the water supply which consisted of three treatments (saturated, three quarters saturated and half saturated soil). Every treatment was repeated three times. Data were analyzed by analysis of variance using the F-test at the 5% level. Significant differences were further tested using Duncan’s New Multiple Range Test also at the 5% level. Treatment with Acaulospora sp and 75% saturated soil gave the best number of leaves and canopy to root ratio. Treatment with Acaulospora sp showed the best results for the number of tillers, stem diameter, root dry weight, and dry weight of the citronella plants. Acaulospora spp promote the growth of citronella grass.

Abstract

Analisis klaster merupakan salah satu analisis multivariat metode interdependensi dikarenakan tidak ada perbedaan antara variabel bebas dan variabel tak bebas. Analisis klaster terdiri dari metode hierarki dan non hierarki. K-Means merupakan salah satu metode analisis klaster non hierarki. Namun, metode K-Means terbatas pada data numerik. Sehingga dibutuhkan metode untuk mengolah data kategorik. Salah satu metode non hierarki untuk data kategorik yang sering digunakan adalah K-Modes. Penelitian ini bertujuan untuk menerapkan analisis klaster K-Modes pada data pasien COVID-19 di RSUD Dr. H. Abdul Moeloek Provinsi Lampung yang berjumlah 560 data pasien dengan variabel jenis kelamin, usia, cara masuk, dan kondisi saat keluar dari RSUD Dr. H. Abdul Moeloek Provinsi Lampung. Dengan menggunakan Davies-Bouldin Index (DBI) dan metode Silhouette, diperoleh hasil nilai  optimal untuk analisis klaster K-Modes adalah sebanyak 8 klaster, yaitu terdiri dari 145 pasien klaster 1, 227 pasien klaster 2, 16 pasien klaster 3, 30 pasien klaster 4, 30 pasien klaster 5, 74 pasien klaster 6, 4 pasien klaster 7, dan 34 pasien klaster 8. Karena anggota klaster 1 dan 2 terbanyak jika dibandingkan dengan klaster lainnya, maka diperlukan penanganan yang lebih optimal untuk klaster 1 dan 2.

Abstract

Garlic is a horticultural commodity that has high economic value. However, the development of garlic in West Sumatra is still limited due to the difficulty in obtaining quality seeds. Quality seeds can determine production, productivity levels and quality of production. Quality seed is also the key to seed acceptance by farmers. The purpose of community service is to introduce quality seeds to farmer groups in Nagari Sungai Nanam, Solok Regency. Sangga Sembalun seed is one of the short-lived national superior varieties. These seeds are suitable for planting in the agro-climatic conditions of Nagari Sungai Nanam, Solok Regency. Through this community service activity, it is hoped that the seeds can be reused as a source of seeds by farmers. The results obtained from these service activities are farmers giving a positive response to these service activities. Sangga Sembalun variety is accepted as seed to be developed by farmers. The farmer group also planted Sangga Sembalun seeds to be used as a source of seeds by group members for the next planting.

Abstract

In principle, shallot can adapt to all altitudes. But in West Sumatera, it is generally cultivated in the highland. The problem is the area in the highland is very limited while the area in lowland land is dominated by Ultisol soils. The type of soil in Agricultural Faculty experimental field at Andalas University is Ultisol (250 asl) but the chemical properties slightly change, such as nitrogen, phosphor and potassium higher than usual otherwise SO42- and Ca-dd is still very low. This study aimed to obtain the best organic fertilizer and ZA fertilizer on the growth, yield and quality of shallot bulb on recovered Ultisols. The research was a-two factorial experiment with 3 replications in Completely Randomized Design. The first factor is the application of various types of organic fertilizer, which include three levels which are guano, chicken manure, and oil palm empty bunches (OPEB). The second factor is ZA fertilizer dosage (0, 100, and 200 kg/ha). Data were analyzed using the F test with a 5% level, and if there were significant differences, the analysis continued with the Duncan’s New Multiple Range Test (DNMRT) at a 5% level. The result showed that the development of shallots on recovered Ultisols brings hope. The yield of chicken manure and guano are higher than oil palm empty bunches and in accordance with the description of Bima Brebes varieties around 9 t/ha. Even guano could produce dry bulbs around10,54 t/ha without giving ZA. Moreover, guano fertilizer gave the best Sulphur content on every dose of ZA.

Abstract

The Nagari Manggopoh is a central area for agricultural product corn, mainly corn for livestock, in Lubuk Basung District, Agam Regency, West Sumatra, Indonesia. The corn kernels produced are sold to animal feed processing factories. However, the corn stalk waste left after harvest is typically burned, leading to land biota damage and air pollution. This community service project aims to raise awareness and demonstrate the process of converting corn plant waste into compost. The project involved socializing, training, and practical demonstrations on composting corn crop waste. These activities have been conducted through counseling sessions, focus group discussions, and hands-on training from June to August 2022. Following the activities, an evaluation was conducted through discussions with the participants. The project's initial result was that ten stakeholders participated in the socialization of using corn crop waste for composting. Additionally, 15 Batang Piarau Jorong Sago farmer group members in Kenagarian Manggopoh have received training and successfully produced compost from corn stalk waste generated from animal feed crops.

Abstract

This research aims to determine the interaction between IBA concentration and growth media composition. Apart from that, determine the provision of IBA and the best composition of growing media for the formation of roots and shoots of rose cuttings. This research was carried out for 4 months, starting from March to June 2022 at the UPT Farm Experimental Garden, Faculty of Agriculture, Andalas University, Padang. The design used was a Factorial Design with 2 factors arranged in a Completely Randomized Design (CRD). The first factor is the provision of IBA which consists of 4 levels (0; 50; 100; 150 ppm). The second factor is the composition of the growing medium which consists of 3 levels: (soil + charcoal husk + cow manure; soil + coconut fiber powder (cocopeat); soil + sand + cow manure). The research data were analyzed statistically using the F test at the 5% level. If the calculated F is greater than the F table of 5%, then proceed with the Duncan's New Multiple Range Test (DNMRT) at level 5. The results of the research show that there is no interaction between the concentration of IBA (Indole-3 butyric acid) and the composition of the growing media in root formation and rose cuttings. The best IBA concentration for forming roots and shoots from rose cuttings is a concentration of 100 ppm, while the best growing medium for forming roots and shoots from rose cuttings is soil + sand + cow manure.
