North Lampung Regency is the main producer of Lampung black pepper, which is generally in the form of a poly-culture system of pepper cultivation. This study aims to study the performance and productivity of the pepper plant which is intercropped with coffee by farmers in North Lampung. This study used a survey method and conducted in North Lampung by taking 2 samples of the sub-districts purposively, namely Abung Barat and Abung Tengah. From each district, 2 villages were selected purposively. Primary data were collected by interviewing 93 sample farmers who were randomly sampled. To deepen the performance of planting, visits and observations of farmers' fields were conducted. The results of this study concluded that: (1) 96% of farmers applied a poly-culture pepper plantation system. Intercropping pepper plantations have a lower pepper plant population but the presence of intercropping can cause land use efficiency to increase by up to 30%;(2) The poly-culture pepper fields  are managed less intensively as indicated by the low fertilizer dosage and the high mortality rate of pepper, which reaches 7-10% of plants per year; (3) The productivity of this intercropping system is pepper yield (conversion of SPH 1600 trees / ha) reaching 230-260 kg / ha or based on factual population reaching 155-267 kg/ha, coffee yield 166-221 kg/ha, and yield of Pithecellobium jiringa 24 -28 kg/tree; (4) According to farmers' perceptions, the main constraints faced by farmers (80.2% of farmers) were the attack of pepper foot rot disease, low prices for pepper, and high mortality of pepper trees. However, most farmers (88.9% of farmers) said they would not replace pepper with other crops.Keywords: Black pepper, coffee, Pithecellobium jiringa, poly-culture, yield

Foot rot disease epidemic on black pepper in variety of environmental conditions. The foot rot disease on black pepper caused by Phytophthora capsici Leonian, is often destructive to farmers of black pepper. This research aims to study the infection rate and the pattern of development of the black pepper foot rot disease in various condition of the environment. The research was conducted in the areas of black pepper cultivation in the Ultisol and Entisol soils. In each location plots were set with few (<25%) and abundant (>75%) weeds. Variable observed was disease incidence. The data were used to analyze model of development of the black pepper foot rot disease and infection rate. Results of the research showed that the model of development of the black pepper foot rot disease was not affected by soil type, but the type of soil affected the infection rate. At the pepper plantation with abundance of weeds, the disease development followes Gompertz model. At the plantation with few weeds, however the disease developed in a logistic model. The rate of disease infection on the black pepper plant with abundant weeds lower compared with those with few weeds.

Abstract. Prayoga GP, Aini SN, Mustikarini, ED, Rosalin Y. 2020. Diversity of black pepper plant (Piper nigrum L.) in Bangka Island (Indonesia) based on agro-morphological characters. Biodiversitas 21: 652-660. Black pepper (Piper nigrum L.) production in Bangka Belitung Islands Province continued to decrease in 2014-2017. Efforts to increase black pepper production was carried out by providing superior varieties that began with an increase in the genetic diversity of black pepper plants. Increasing the genetic diversity of black pepper can be done through black pepper germplasm exploration activities followed by characterization. The research aimed to obtain the agro-morphological characteristics of black pepper plants in Bangka island. Exploration was carried out by survey method in four regencies in Bangka Island. The research method used a survey method with convenience sampling technique. Observation of agro-morphological characters was carried out in accordance with the descriptor for black pepper from IPGRI (1995). The results of exploration of black pepper plants in Bangka Island have found 9 accessions of black pepper plants, consisting of 5 cultivars were Lampung Daun Lebar (LDL), Lampung Daun Kecil (LDK), Chunuk, and Jambi and 4 landraces namely Bogor, Peremis, Keriwil, and Merapin Daun Kecil (MDK). There were morphological differences in 9 accessions of black pepper plants, namely leaf lamina shape, leaf vein, leaf margin, lateral branch habit, leaf base shape, ripe fruit color, hanging vines, ground vines, and stem shape. Agro-morphological relationship of 9 accessions of black pepper plants can be divided into 5 clusters at a 50% similarity level. Based on this study, black pepper breeding program on Bangka Island could be done accessions of Peremis, Bogor, Nyelungkup, and Jambi as genetic sources. Furthermore, selection would be better to use length of petiole, length of stem segment, fruit size, percentage of perfect fruit, weight of 1000 fruits, and the weight of 1000 dried seeds as the selection criteria.

Wild pepper of Piper colubrinum Link is used as rootstocks for grafted black pepper (Piper nigrum/Piper colubrinum) because its resistance to fungi that cause root rot disease. Grafted black pepper nurseries and plantations began to be developed by farmers in Lampung. This research aims to study the growth characteristics of wild pepper and grafted black pepper plants. The research was conducted in the field of wild pepper and grafted black pepper owned by farmers in Air Kubang Village, Air Naningan District, Tanggamus, Lampung, using survey method. Plant samples were determined randomly in the fields. The results showed that: (1) Wild pepper plants starts at the age of 1 year form plagiotropic branches with small diameters every 1-2 orthotropic branches, but slowly form orthotropic branches; (2) After the second pruning (of harvesting cuttings) 22% of the plants form orthotropic branches. The yield of pepper cuttings from the first to third harvests increased by 21-25% compared to the previous yield. In the third harvest, the production of cuttings reached 5066 cuttings (2 nodes) per 400 m2 land area or equivalent to 126,650 cuttings per ha of land harvested every 2 months; (3) At the age of 18 months, compared to non-grafted, grafted black pepper showed a greater greeness leaf index, larger stem diameter, larger plagiotropic branch diameter, higher number of orthotropic and plagiotropic branches, and 15.6% of grafted black pepper plants were flowering. Key words : Black pepper, cutting, flowering, growth, grafting, Piper colubrinum

The purpose of this study was to find out the function of cold storage in stabilizing fish prices in Ambon City, analyzing optimal production levels of various types of dominant fish, and analyzing the level of efficiency of utilization of cold storage and auxiliary machinery. This study uses the survey method. Primary data collection through questionnaires is built empirically while secondary data is obtained from several agencies related to this study. The research sample was drawn by exhausting sampling, amounting to 6 cold storage units in Ambon City. The role of cold storage to stabilize fish prices was analyzed using a qualitative descriptive approach, while the quantitative techniques used included analysis of optimization of cold storage production with linear programming and analysis of the efficiency of utilization of cold storage. The results of the study show that cold storage has not played a role properly to stabilize fish prices in Ambon City. To achieve optimal use of production factors, the cold storage management needs to reduce the raw material by 24,915.9 kg / month; 7 HOK / month workforce; cold storage storage space capacity of 2.09 kg / month; and demand for flying fish 1,402.6 kg / month, while the use of production factors efficiently (fully utulized) is the capacity of the freezing machine, demand for tuna, skipjack, and cob. The level of technical efficiency of the utilization of cold storage facilities is reached, the total use of installed capacity must be proportional to the capacity used.


The study was conducted using purposive cum random sampling technique and two hundred respondents comprised of 100 each borrowers and non-borrowers were selected from two block of district including marginal, small and medium categories of farm size. Primary data were collected through personal interview technique and required secondary information was taken from the record available at district and block level. Simple tabular and functional analysis and Garrett ranking were done to draw inferences. As per the result obtained from the study, no much difference was seen between the resource use efficiency of borrower and non-borrower farms and constraints faced by borrower. Since banana is a cash crop and it needs initial costs for its establishment, and after harvesting the crop regular source of income was generated by selling of suckers (seed) plant and its fruits. It’s by-product, leaves, etc. also used for various purposes. Minute inspection of the analysis showed that finance played important role for initiating the cultivation of banana crops showed the resource use efficiency that there is no considerable difference found on sample farms of borrower and non-borrower categories. Constraints faced by majority of the farmers were mainly delay in disbursement of loan and lack of the repayment period insufficient and improper management for withdraws on KCC.

ABSTRACT THE EFFECT OF HOUSEHOLD INCOME ON MEAT CONSUMPTION (BEEF, PORK AND CHIKEN) AT THE VILLAGE OF SEA I, PINELENG DISTRICT.This study aims to determine the magnitude of meat consumption (beef, porl and chiken) of household based on income levels in the Village of Sea I, Pineleng district and to determine the effect of household income on meat consumption (beef, porl and chiken) in the Village of Sea I, Pineleng district. Formulation of research problem is how much they purchased meat (beef, porl and chiken) consumption household in the Village of Sea I, Pineleng district. This study was conducted in the Village of Sea I, Pineleng district. Study was conducted using a survey method, and data were obtained through primary data and secondary data. Determination of the location (rural sample) in the study was conducted by purposive sampling method. Number of samples used in this study were 30 people. Data of this study were analyzed by descriptive and mathematical analysis methods. Income indicated the amount of income earned in a month household, whether they were from the household head or sourced from other household members who work and earn income. From the money earned, the highest number of respondents had incomes between 1.000.000 to 3.000.000/month with the percentage of 70 %, while the number of respondents with the smallest income was less than 1.000.000/month with the percentage of 16.67 %. The difference of income held by the respondents in the Village of Sea I, would have an impact on the amount of meat purchases each month. This was in accordance with the opinion Sukirno (2002) stating that most of the disposable income is used to buy food and clothing. Most of the meat consumed by people in the Village of Sea I was pork and chicken meat compared to beef, it was because the price of beef was relatively expensive compared to the price of pork and chicken meat. Based on research results, pork was the most meat consumed by family respondents about 21 families with the percentage of 70 % of respondents, followed by chicken meat about 18 families with the percentage of 60 % of respondents, and beef by 8 families with the percentage of 26 respondents, 67 % of domestic poultry and meat about 6 families with the percentage of 20 % of respondents. Based on the results of research, it can be concluded that household income significantly affect the consumption of meat in the Village of Sea I, Pineleng district and the average consumption of meat in the Village of Sea I, Pineleng district was about 8,9  kg/capita/year, below the national target of 10,3  kg/capita/year.   Key Words : Household income, meat consumption, Sea I Village.

Rapid urbanization has provided a strong impetus for the economic growth of China, but it has also caused many problems such as inefficient urban land use and environmental pollution. With the popularization of the concept of green and sustainable development, the Environmental-Social-Governance (ESG) assessment concept is widely accepted. The government and residents are paying more and more attention to environmental issues in urban development, and environmental protection has formed an important part of urban development. In this context, this study takes 26 cities in the Yangtze River Delta as examples to build an evaluation system for urban land-use efficiency under green development orientation. The evaluation system takes into account the inputs of land, capital, labor, and energy factors in the process of urban development. Based on emphasizing economic output, the social benefits and undesired outputs brought about by urban development are taken into account. This paper measures urban land use efficiency by the super-efficiency SBM model, and on this basis, analyses the spatial-temporal evolution characteristics of urban land-use efficiency. Further, this paper measures urban land use efficiency without considering undesired outputs and compares the two evaluation methods. Again, the comparison illustrates the rationality of urban land use efficiency evaluation system under green development orientation.

The construction and operation of high-speed rail (HSR) has become an important policy for China to achieve efficiency and fairness and promote high-quality economic growth. HSR promotes the flow of production factors such as labor and capital and affects economic growth, and may further affect urban land use efficiency (ULUE). To explore the impact of HSR on ULUE, this paper uses panel data of 284 cities in China from 2005 to 2018, and constructs Propensity Score Matching-Differences in Differences model to evaluate the effect of HSR on ULUE. The result of entire China demonstrates that the HSR could significantly improves the ULUE. Meanwhile, this paper also considers the heterogeneity of results caused by geographic location, urban levels and scales. It demonstrates that the HSR has a significantly positive effect on ULUE of Eastern, Central China, and large-sized cities. However, in Western China, in medium-sized, and small-sized cities, the impact of HSR on ULUE is not significant. This paper concludes that construction and operation of HSR should be linked to urban development planning and land use planning. Meanwhile, the cities with different geographical locations and scales should take advantage of HSR to improve ULUE and promote urban coordinated development.
