This study was carried out experimentally consi…
ABSTRACT Peptone is a protein hydrolysate that is easily damaged when stored at room temperature. This situation underlies the need for storage in the refrigerator to extend the storage length. The study aimed to obtain the optimal shelf life of halal peptones from catfish waste at a temperature refrigerator by looking at the growth characteristics of lactic acid and pathogenic bacteria inocul…
ABSTRACT This study aims to analyze the right strategy for oil palm fruit collectors in increasing competitiveness using the Strength Weaknesses Opportunity Threats (SWOT) and Analytical Hierarchy Process (AHP) methods. The method used in this study is observation with a qualitative descriptive approach. Qualitative descriptions were obtained through direct interviews with collectors using a p…
Mung bean (Vigna radiate L.) is an important arable crop commodity and potential to be cultivated in Indonesia. Seed of mung bean contain almost complete nutrition including carbohydrate, protein, lipid, vitamins and trace elements. Production of mung bean in Indonesia and specifically in Riau Province tended to decrease from year to years in the last several years. The decrease in mung bean pr…
This research was conducted to study the performance of Banting Dura x Pisifera Avros (DxP) progenies on yield and oil analysis components that planted on inland soil at Siak, Riau. Ten DxP progenies and two DxP controls were used for this study. They were evaluated for fresh fruit bunch (FFB), fruit components and oil content traits. FFB production for most of the progenies compare to the …
Differences in soil types, water table regimes, and technological inputs in smallholder oil palm plantations on acid sulfate soil lead to the formation of distinct land units within the plantations. There are four different land units identified, each with its unique characteristics. These differences in characteristics result in variations in the properties and performance of oil palm plan…
Peat soil fertility is classified as low which is characterized by soil chemical properties, including low pH (acid), availability of macro (K, Ca, Mg, P) and micro (Cu, Zn, Mn, and Bo) nutrients, low cation exchange capacity (CEC) is high but Base Saturation (BS) is low. In increasing nutrient availability and absorption in plants, mycorrhizal materials are needed which can increase the ab…
This study aimed to evaluate the improvement in growth and yield of M8 generation mung bean plants (Vignaradiata L.) resulting from gamma ray mutation, in an effort to obtain plants with synchronous pod maturity characteristics and high pod weight production. The study employed a completely randomized design (CRD), involving a population of parent plants and 4 progenies, namely M8-18-3-1-6…
Green beans (Vigna radiata L.) is a plant that is widely cultivated in Kampar Regency, Riau. Mung bean productivity in Indonesia and the Kampar district tends to be stable every year, but mung bean farmers in the Kampar district generally cultivate green beans from the local Kampar strain which have low yield, have trichomes and pods that break easily. One of the efforts that can be made to…
Soil macrofauna measuring > 2 mm consists of milliapoda, isopods, insects, molluscs and earthworms (Maftu'ah et al., 2005). Soil macrofauna has an important role in the decomposition of soil organic matter in the provision of nutrients. Macrofauna will crumble dead vegetable matter, then the material will be excreted in the form of feces. The presence of soil macro, meso and microfauna has a ro…
Peatlands in Indonesia are widely used for the development of plantation crops, one of which is oil palm. The development of peatlands faces many obstacles, such as the reaction of acidic to very acidic peat soils with high cation exchange capacity (CEC) and the availability of nutrients in a bound form. These conditions do not support plant growth in general. The solution to solve the problem…
Oil palm is an important plantation commodity in Indonesia which has high productivity. The growth of oil palm is inseparable from disease disturbances. Oil palm stems base rot disease is caused by the fungus Ganoderma sp. Morphological identification determines the success of stem rot disease control efforts. Trichoderma sp. is a fungus that is antagonistic to Ganoderma. Trichoderma origi…
Acacia crassicarpa A.Cunn. ex Benth is a type of fast-growing tree species that is highly adaptable and tolerant of extremely environmental conditions. Acacia crassicarpa is a type of forest plant that has harvested period of approximately 5 years. Economically, the acacia is used as a wood source for processed into wood pulp, paper, and fuel potential for charcoal production. One of the e…
ABSTRACT Biodegradable plastics is plastic made from renewable resources and can be decomposed by the action of living organisms. Biodegradable plastic can be made from starch from cassava peels and cellulose from pineapple leaves. The purpose of this study was to obtain the best ratio of cassava peel starch and pineapple leaf cellulose to the characteristics of the resulting biodegradable pla…
ABSTRACT This study aims to obtain the best characteristics of biodegradable plastic made from sago starch with the addition of palm frond fiber cellulose. This research was conducted experimentally using a completely randomized method (CRD) with four treatments and four replications. The treatment in this study was the addition of cellulose fiber from palm fronds 10%, 20%, 30% and 40%. Tests …
ABSTRACT Banana bunch is a potentially large biomass and is only disposed of as waste. Banana bunch can be utilized in high-value-added products such as pectin. Pectin is an industrial material obtained by extraction from plant tissue and can be influenced by various factors, including temperature extraction. Temperature extraction is one factor that will determine pectin's properties and feat…
ABSTRACT Robusta coffee has higher caffeine than other types of commercial coffee. High levels of caffeine in robusta coffee can hurt health. One of the efforts to reduce this impact is by the decaffeination process. Decaffeination can be carried out enzymatically with the bromelain. Bromelain from pineapple peel can hydrolyze caffeine molecules that have a structure similar to proteins. The s…
