Selada (Lactuca sativa) merupakan tanaman hortikultura yang banyak dibudidayakan petani secara intensif. Tanaman tersebut merupakan tanaman semusim yang dapat di budidayakan di daerah lembab, dingin, dataran rendah maupun dataran tinggi. Penelitian ini merupakan percobaan Faktorial dengan 2 faktor yang disusun menggunakan Rancangan Acak Lengkap (RAL). Faktor pertama adalah dosis Kompos Azolla (K) yang terdiri atas 4 taraf dosis dan faktor kedua adalah dosis pupuk urea (U) yang terdiri atas 4 taraf dosis. Perlakuan kombinasi dari dua perlakuan dihasilkan 16 kombinasi perlakuan yang masing-masing diulang 3 kali, sehingga terdapat 48 satuan percobaan, dimana masing-masing satuan percobaan diamati 3 tanaman. Penelitian ini dilatarbelakangi oleh menurunya jumlah produksi tanaman selada setiap tahunya. Penurunan nilai produksi selada dikaitkan dengan buruknya teknik budidaya yang dilakukan. Kompos Azolla dan pupuk urea menjadi solusi terbaik untuk meningkatkan jumlah prosuktifitas tanaman selada serta meminimalisir peggunaan pupuk kimia yang berlebihan.

Marketing strategy is an essential component of any business operation. Whether a business is successful depends on whether its marketing strategy is effective for its needs. Therefore, the selection of a marketing strategy requires precise calculations and analysis. According to the title observed, the method used in this study is a qualitative research method that generates descriptive data through observations, interviews, and documentaries. Cordova Living is a housing community that employs a sharia payment system, eliminating the BI checking system so that there are no interest, usury, confiscation, or fines. Based on the fact that Cordova Living was the pioneer of sharia-compliant housing in Tasikmalaya, the sharia marketing strategy is a great fit for marketing its products. As evidenced by the marketing mix, implementing sharia marketing strategies can increase sales figures and the selling value of Cordova Living housing. In terms of price (price) has advantages for consumers to negotiate because of the khiyar rights. In terms of products, transparency from start to finish, detailed explanations, and the freedom to bargain and negotiate can eliminate the element of fraud. The strategic place (location) close to the city center and education center provides added value for Cordova Living. The promotion (promotion) used by Cordova Living is friendly and applies 3S (senyum/smiles, salam/greetings, and sapa/greetings) and friendly service by applying Islamic rules.

The konjac plant (Amorphophallus oncophyllus Prain.) contains high glucomannan with many benefits. This experiment aimed to study effect of paclobutrazol dose and seedling size on the growth and yield of konjac plants. The research was arranged factorially based on a Completely Randomized Design with two factor. The first factor (paclobutrazol dose) consisted of P0: 0.0 g/plant, P1: 0.05 g/plant, P2: 0.10 g/plant, P3: 0.15 g/plant, P4: 0.20 g/plant. The second factor (seed size) consisted of U1: 20-50 g/seed, U2: 100-150 g/seed, U3: 200-250 g/seed. Observation parameters included plant height, canopy diameter, stem diameter, stem sturdiness, number of buds, weight and diameter of tubers. Results showed that paclobutrazol dose of 0.20 g/plant had a significant effect on stem sturdiness, weight and diameter of the tubers. The maximum of tuber weight obtained by paclobutrazol application of 0.2 g/plant was estimated to be 1,533 g with tuber diameter of 167 mm. Small size seed (20-50 g) produced the largest number of buds and did not differ markedly from those of medium size seed (100-150 g). Large size seed (200-250 g) produced the best konjac plants in term of canopy diameter, stem sturdiness, weight and diameter of tubers. Keywords : Dosage, Konjac, Paclobutrazol, Seed Size, Tuber Size

This study aims to determine the best of combination treatment of pruning type and concentration of liquid organic fertilizer (LOF) on the growth and yield of pepper plants whose production is still low and has not yet achieved its production potential which can reach 20 tons/ha. The factorial study with 2 factors was arranged in a completely randomized design (CRD) which was repeated 3 times. The first factor is the type of pruning (P) which consists of 3 levels, namely: P0 = Not pruned (control), P1 = Pruning shoot tip, P2 = Pruning axillary shoot, while the second factor is the concentration of LOF NASA which consists of 3 levels , namely: K0 = 0 ml/l (control), K1 = 2 ml/l, and K2 = 4 ml/l. The results showed that there was a significant interaction between the combination of shoot pruning treatment and LOF NASA concentration on the number of branches and the number of productive branches. The combination of shoot trimming treatment and LOF NASA concentration of 2 ml/l water (P1K1) resulted in the best growth of pepper. Meanwhile, the single factor type of shoot tip pruning (P1) and LOF NASA concentration of 2 ml/l (K1) produced the best number of fruits and fruit weight of papper compared to other treatments.

Avocado is a fruit crop that is commercial and potential to be widely cultivated. Market demand for avocado was increased so production of avocado seed must increase too by grafting. The problem of grafting is often found in the connection between scion and rootstock that showed like elephant foot phenomenon, so it was necessary to study the linkage process between scion and rootstock. This research leads up to an increased percentage of finished graft seedlings that were ready for planting in the field. This method used a factorial experiment consisting of 2 factors. The first factor was the stages of entres (flushing, endodormancy, and ecodormancy), and the second factor was the grafting method (cleft graft, wedge graft, and splice graft). The research design used Complete Randomized Design with 4 replications and ANOVA with BNJ 5% test. The results showed all observations parameters interacted. Stage ecodormancy in splice graft resulted of vascular tissue (xylem and phloem) between scion and rootstock recovered better than other combination treatments by producing the best-grafted avocado seedlings growth with an increased percentage of grafted seedling by 42.50%, an interval of flushing by 4.91 days, and increased frequency of flushing by 1.83 times compared to stage flushing in cleft graft.

Empowerment of Sumber Abadi Forest Farmer Groups through Innovation of Porang Nursery Techniques. Forest Farmers Group (FFG) Sumber Abadi is located in Panglungan Village, Wonosalam District, Jombang Regency, whose area is 500-750 m asl and daily temperature of 20° C. The conditions of socio-economic need to be improved, considering that their livelihoods depend on forest products and half of the population belongs to the category of pre-prosperous families. Panglungan village has the largest porang area and has the potential for a profitable porang seed business, encouraging farmers to carry out traditional nurseries to fulfill the increasing demand for seeds. Porang is a super strategic commodity and prospectus as a healthy food, low carbohydrates and high fiber, and a high tuber selling price (Rp 10,000,-/kg). Obstacles in the porang nursery business in Panglungan Village, namely: (1) lack of understanding of proper nursery techniques, (2) weak innovation of porang nurseries, (3) lack of understanding of seed supply chain management, and (4) weak of institutional functioning. The aim of the activity is to increase empowerment through innovative porang nursery techniques. Empowerment methods include: (1) training on innovation in porang nursery technology on various seed sources, (2) demonstration plots for porang nurseries, (3) economic empowerment of rural communities, (4) training on marketing porang seeds online. The results of the empowerment of FFG Sumber Abadi showed that there were 2 groups of porang seed breeders who were innovative in seeding techniques and marketing with a volume of more than 2 million seeds that lasted for 5 months.

Pressure vessel is a container for a fluid, both liquid fluid and pressurized gas. In designing a pressure vessel, there are several things that must be considered, namely the stress that appears on the vessel wall due to the pressure caused by the fluid in the vessel, the weight of the vessel itself, or due to pressure arising from external factors. The process of making pressure vessels is carried out using the rolling process and the assembly welding process. The welding process must be considered based on the level of density, leakage and at the same strength. Planning the welding procedure to be carried out on the pressure vessel, the first welding process carried out is Head, Shell 1 body, Shell 2 Body, Shell 3 cone, Shell 4 cone, and Bottom Plate. The material to be used is SA 516 GR 70 according to ASME (American Society of Mechanical Engineers) section II D. Welding process using GMAW (Gas Metal Arc Welding), welding connection planning, welding parameters and everything related to the welding process is determined and summarized on WPS (Welding Procedure Specification) based on ASME (American Society of Mechanical Engineers) section IX. Testing on the welding results is carried out in several stages starting from the penetrant test, radiography test, peneumatic test, and hydrostatic test. The test is carried out to determine the quality of the welding results. Then an analysis of the results of the welding that has been tested is carried out to really know the quality of the standardization used. Based on the results of several stages of testing on the GMAW (Gas Metal Arc Welding) welding process with the standardization used, there are still defects in the welding results.
