Shallot is the most produced vegetable in Indonesia. The consumption of shallot per kg/capita/year is continuously increasing, therefore there is a need to ensure enough supply. The lack of nutrients in the soil is a problem in shallot production. Shallot needs macronutrients such as Nitrogen (N), Phosphorus (P), Potassium (K), and Calcium (Ca) to improve its yield and quality. The application of liquid organic fertilizer from coconut husk and dolomite can be the solution. This study was conducted using Factorial Randomized Block Design consisting of two factors, concentration of liquid organic fertilizer (0%, 10%, 20%, and 30%) and dolomite (with dolomite or without). The results showed that the application of 20% liquid organic fertilizer, the application of dolomite, and the combination of both (P2D1) had the highest value on fresh shallot bulbs weight per clumps and bulb weight after storage parameters, and had the lowest value on weight loss percentage parameter.

The yellow sap is produced naturally in mangosteen organ except in the root. The yellow sap contaminated the aryl and rind if the epithelial cell walls rupture due to deficiency of calcium (Ca). Calcium is one of structural component of cell walls, whereas naphthaleneacetic acid (NAA) has its role in improving cell division and cell elongation. Interaction of Ca and NAA can improve sink strength and capacity because the newly formed cells need Ca to construct wall structure. This experiment aimed at finding out the effect of Ca and NAA applications in reducing the contamination of yellow sap in mangosteen. The experiment was conducted by using factorial random block design consisting of 2 factors and 3 replications. The first factor was Ca dosage (0 and 4.8 kg/tree), and the second factor was NAA concentration (0, 200, 400 and 600 ppm). The results showed that application of 4.8 Ca/tree and 200 ppm NAA as much as 5 ml / fruit effectively improve the content of Ca pectate in pericarp, reduced the percentage of yellow sap contamination on the fruit segment, aryl and rind to 0% and 12.3% respectively compared to control (17.8% on fruit segment, 36.8% on aryl and 56.1% on rind).Key words: aryl, Ca pectate, cell wall, middle lamela.ABSTRAKGetah kuning adalah getah yang dihasilkan secara alami pada setiap organ manggis, kecuali pada akar. Getah kuning akan keluar dan mencemari aril serta kulit jika dinding sel epitel pecah karena kekurangan kalsium (Ca). Kalsium adalah komponen dinding sel, berperan dalam struktur dan permeabilitas membran sedangkan asam naftalenasetat (NAA) berperan penting dalam meningkatkan pembelahan dan pembesaran sel. Interaksi keduanya dapat meningkatkan kapasitas sink buah karena sel yang baru terbentuk membutuhkan Ca dalam menyusun struktur dinding sel. Percobaan bertujuan untuk mengetahui pengaruh aplikasi Ca dan NAA dalam menurunkan cemaran getah kuning manggis. Percobaan menggunakan rancangan acak kelompok faktorial 2 faktor dengan 3 ulangan. Faktor ke-1 yaitu dosis Ca (0 dan 4.8 kg Ca/pohon) dan faktor ke-2 yaitu konsentrasi NAA (0, 200, 400 dan 600 ppm) dengan volume semprot 5 ml perbuah. Hasil percobaan menunjukkan bahwa aplikasi 4.8 kg Ca/pohon dengan NAA 200 ppm sebanyak 5 ml/buah efektif meningkatkan kandungan Ca pektat perikarp dan menurunkan persentase buah tercemar getah kuning menjadi 0% pada juring dan aril serta 12.3% pada kulit dibandingkan dengan perlakuan kontrol (17.8% pada juring, 36.8% pada aril dan 56.1% pada kulit buah).Kata kunci: aril, Ca pektat, dinding sel, lamela tengah

Cayenne pepper is a vegetable plant that has great potential to be developed in Indonesia because it can meet the needs of households, domestic industries, exports, and raw materials in the pharmaceutical industry. One way to increase the yield of cayenne pepper is by giving liquid organic fertilizer (POC) for bamboo shoots. This study aims to determine the response of cayenne pepper toward the application of POC and gets the best POC concentration to support the growth and production of cayenne pepper. This study used a randomized block design with treatment in the form of POC concentrations consisting of 5 levels (0; 25 ml / L water; 50 ml / L water; 75 ml / L water; 100 ml / L water). Each treatment consisted of 4 replications so that there were 20 experimental units. The results show that the application of POC had a very significant effect on the number of flowers, fresh weight of fruit, and growth rate of cayenne pepper with the best treatment was 75 ml / L of water.

This activity aims to develop partners' knowledge and skills regarding liquid organic fertilizers (LOF) and growth regulators (GR) through counseling and training in the form of technical assistance and guidance. Implementation methods included extension, manufacture of LOF and GR, application to plants, and evaluation. The target of the implementation of this service was patchouli farmers in Nggawia Village. The initial evaluation instrument was in the form of a questionnaire, while the final evaluation was only in the form of questions and answers during the implementation of the activity. In addition, a simple experiment was carried out on patchouli plants to determine the effectiveness of LOF and GR. The questionnaire, discussion, and experiment results were described based on the data obtained and the experimental parameters. This activity showed that the training on making LOF and GR has succeeded in increasing the knowledge and skills of farmers in Nggawia Village, West Tojo District, Tojo Una-Una Regency. The average plant height and number of shoots applied by POC and POC coconut water was higher than control, and only POC or ZPT was used singly.
