Abstract

Molluscicide made from areca nut is an alternative pesticide to control snail pests. Comparing the effects of solid (powder) and extract (liquid) types of molluscicide is an effort to develop these pesticides. This study was aimed to compare the effect of using molluscicide with active ingredients of fentin acetate, areca nut powder, and extracts on golden snails in rice plants. The study used a randomized block design (RCBD), with two factors. The first factor was the type of molluscicide, namely fentin acetate, powder, and areca nut extract. Meanwhile, the second factor was the dose consisting of the recommended dose and half the recommended dose. There were 6 treatment combinations that were 5 replications. The research data consisted of mortality rates, 1, 2, 3, 7, and 14 days after applications. Data were analyzed used non-parametric analysis of variances by Kruskal-Wallis and Man Whitney Test. The results showed that there were effects of fentin acetate, areca nut powder, and extract on the mortality rate of the golden snails. The mortality rate reached 50%-75% at 3 days applications and reached 98%-100% at 7 days after applications. Furthermore, there was also showed that areca nut powder molluscicide could be an alternative to synthetics molluscicide because the areca powder nut powder tended to be more effective than other pesticides with half the recommended dose.

Abstract

Rice is the leading food and a carbohydrate source for most of the world's and Indonesia population, but most rice tends to have a high glycemic index (IG). A product with a low IG is better, not only for people with diabetes but also for healthy people. Resistant starch (RS) functions as a new food ingredient that has a low glycemic index. RS is a part of starch or starch products resistant to digestion when through a gastrointestinal tract. RS has the same physiological effects as dietary fiber, can affect body weight and energy balance, increase lipid excretion to reduce calorie intake and reduce serum lipid levels, zero caloric content so that it can be used as a low-calorie food additive that can control body weight effectively. RS can be made through starch modification by physical treatment (heat treatment), chemical treatment, enzymatic treatment, and a combination of heat and enzymatic. Factors that influence RS's formation include starch properties, starch interactions with other components, processing conditions, heat processes, other treatments, and storage conditions. Therefore, the rice starch modification that contains a lot of RS needs to be known. Rice starch Hydrolysis with the dual enzyme α-amylase and pullulanase (DMT) can increase the highest RS level (51.0%) due to the increased degree of starch crystallinity. High RS results in an increase in gelatinization temperature, ΔH and phase transition temperatures, and a decrease in the speed of starch hydrolysis and weight loss.

Abstract

Tujuan dari penelitian ini adalah menganalisis pengaruh kemiringan pipa outlet terhadap efisiensi pompa hidram, mengetahui debit aliran, kecepatan aliran  pada bagian pipa outlet hasil dari pemompaan pompa hidram. Penelitian ini dilakukan dengan menggunakan metode eksperimental dengan proses trial dalam skala laboratorium. Batasan masalah pada penelitian ini adalah menggunakan pipa inlet dengan panjang 4 m dengan diameter 1 inch dan panjang pipa outlet 4 m dengan diameter ½ inch. Ketinggian head pemasukan adalah 1,5 m. Kemiringan sudut pipa outlet yang digunakan adalah 120o, 140o, dan 160o. Pengukuran parameter pada penelitian ini dilakukan dengan mengukur volume air yang keluar dari pipa outlet dan yang keluar dari katup limbah. Volume yang didapatkan digunakan untuk menghitung debit aliran, kecepatan aliran, bilangan reynolds serta nilai head losses. Data yang telah diperoleh dianalisis menggunakan pendekatan matematik yang diselesaikan menggunakan program Ms excel dan secara manual menggunakan kalkulator. Berdasarkan hasil pembahasan diketahui bahwa nilai debit mengalami kenaikan  karena dipengaruhi oleh sudut kemiringan pipa outlet yang semakin besar. Bilangan reynolds pada hasil pemompaan memiliki jenis aliran laminar. Nilai efisiensi yang mendekati 100% didapatkan pada sudut outlet 160o yaitu sebesar 99,51% (Efisiensi Rankine) dan 99,67% (Efisiensi D’Aubuission) dengan panjang pipa yang sama.

Abstract

Plant growth-promoting rhizobacteria are names that contribute directly or indirectly to plant growth. This group of bacteria will stimulate plant growth through the synthesis of phytohormones (bio-stimulant). Indole acetic acid (IAA) plant endogenous auxin is one of the phytohormone type that these bacteria can generate. IAA has functions for root elongation, cell division and plant growth and development differentiation. This research aims to obtain possible isolates that can generate IAA to optimize the viability of germinating red pepper seed. Bacteria have been isolated by serial dilution spread of Nutrient agar medium was incubation over a 24-hour period at 28oC (room temperature). The amount of IAA was measured by spectrophotometric analysis, selected isolate on the basis of the results, used to encourage the germination of red pepper seed. Ten out of sixteen bacterial isolates could produce IAA in the range of 7.96 ppm - 47.23 ppm. The RC 3 isolate produced the highest IAA while the RC 12 was the other way round. The isolate chosen using this experiment showed an increase in the viability of red pepper seed compare seed germination to 33%, growth spontaneity 37%, vigor index 10%, growth rates 6% and max. growth 13%. IAA isolates could therefore increase the viability of red pepper and got potential of a biofertilizer component.

Abstract

The development Slow Release Compost Tablet can be used as a solution for the management of cow dung bioslurry by farmers. Bioslurry is a reject product from processing waste into biogas. The purpose of this study was to determine the physical characteristics of tablet compost made from cow dung Bio-slurry. The research design used a completely randomized design (CRD) with two factors, namely the composition of the addition of hydrogel  and silica from geothermal waste from the eruption of Mount Rinjani with five levels of treatment, namely; T1 (30gr hydrogel : 50gr silica powder); T2 (60gr hydrogel : 40gr silica powder); T3 (90gr hydrogel : 30gr silica powder); T4 (120gr hydrogel : 20gr silica powder); T5 (150gr hydrogel : 10gr silica powder). The results showed that the dimensions, weight, and hardness of tablet compost were not significantly different. The treatment without the addition of hydrogel  has the highest hardness value. The higher the hydrogel  addition, the lower the tablet compost hardness value.
